How to Overcome Math Anxiety

How to Overcome Math Anxiety Do you feel a little flushed when you think about doing math homework? Do you think youre no good at math? If you find yourself putting off your math work or dreading math tests, you may suffer from math anxiety. What Is Math Anxiety? Math Anxiety is a type of fear. Sometimes fear is merely the dread of some unknown that lurks out there. How do you conquer this type of fear? You isolate it, examine it closely, and understand what its made of. When you do this, youll soon find that the fear goes away. There are five common factors and feelings that make us avoid math. When we avoid it, we lose confidence and then start building up dread and fear. Lets confront the things that cause us to avoid math! Im Just Not Cut Out for Math Sound familiar? Actually, there is no such thing as a brain type that makes one person better than another at math. Yes, studies show that there are different brain types, but those types just concern your approach at problem solving. Your approach can be different from another students, but it can still be just as effective. One factor that affects math performance more than any other is confidence. Sometimes a stereotype can make us believe that we are naturally less capable than others. Studies have shown that math stereotypes are not true! Interestingly, studies do show that positive thinking can improve math performance. Basically, there are two things that you can do to really and truly improve your math performance: Dont accept stereotypes about mathThink positive thoughts. If you are smart at any skill at all, then you can be smart at math. If you are good at writing or foreign language, for instance, that proves you can be smart at math. Building Blocks Are  Missing This is a legitimate cause for anxiety. If you avoided math in lower grades or you just didnt pay enough attention in middle school, you may be feeling stressed out because you know your background is weak. There is good news. You can overcome this problem easily by skimming through a textbook that was written for a level slightly lower than your current class. First, youll be surprised at how much you do know. Secondly, youll find there are only a few skills you need to practice before youre completely caught up. And those skills will come easily! Want proof? Think about this: There are many, many adult students who start college after being out of class for ten and twenty years. They survive college algebra by brushing up quickly on forgotten (or never acquired) basic skills using old text books or a refresher course. Youre not as far behind as you think you are! Its never too late to catch up. Its Just So Boring! This is a false accusation. Many students who like the drama of literature or social studies may accuse math of being un-interesting. There are many mysteries in math and science! Mathematicians enjoy debating approaches to long-unsolved problems. From time to time, somebody will discover the solution to a problem that others have sought for years. Math poses challenges that can be amazingly gratifying to conquer. Additionally, there is a perfection to math that cant be found in many places on this earth. If you like mystery and drama, you can find it in the complexity of math. Think of math as a great mystery to solve. It Takes Too Much Time It is true that many people suffer real anxiety when it comes to setting aside a certain span of time and committing to it. This is one of the factors that often leads to procrastination, and it manifests in people of all ages. For example, many adults put off tasks when they know they will have to devote themselves completely for an hour or two. Perhaps, deep down, were afraid well miss out on something. There is just a certain amount of anxiety or fear that comes with stepping out of our life for an hour or two and focusing on one specific thing. This explains why some adults put off paying bills or doing odd jobs around the house. This is one of those fears that we can overcome, just by acknowledging it. Realize that its normal to resist devoting an hour of your thoughts to your math homework. Then simply think your way through your fear. Think about the other things in your life that youll need to set aside. Youll soon realize that can do without them all for an hour or two. Its Too Complex to Understand It is true that math involves some very complex formulas. Remember the process for overcoming any fear? Isolate it, examine it, and break it down into little parts. Thats exactly what you have to do in math. Every formula is made of little parts or skills and steps that youve learned in the past. Its a matter of building blocks. When you come across a formula or process that seems too complex, just break it down. If you find that youre a little weak on some of the concepts or steps that make up one element of the formula, then just go back and work on your building blocks.

Admiral Edward Vernon of the Royal Navy

Admiral Edward Vernon of the Royal Navy A distinguished officer in the Royal Navy, Admiral Edward Vernons career commenced in 1700 and spanned a period of 46 years. This saw him learn his trade under Admiral Cloudesley Shovell before establishing himself as a rising star in the ranks. Vernon saw active service in the War of the Spanish Succession (1701-1714) and later in the War of Jenkins Ear and the War of the Austrian Succession. Though he won a triumph at Porto Bello in 1739, he is best remembered for his invention of grog, a rum and water mixture, that was provided to the sailors in his fleets. Grog would go on to become a staple of Royal Navy life until 1970. Early Life Career Born November 12, 1684 in London, Edward Vernon was the son of James Vernon, secretary of state to King William III. Raised in the city, he received some education at the Westminster School before entering the Royal Navy on May 10, 1700. A popular school for the sons of well-placed Britons, Westminster later produced both Thomas Gage and John Burgoyne who would play key roles in the American Revolution. Assigned to HMS Shrewsbury (80 guns), Vernon possessed more education than most his peers. Remaining aboard for less than a year, he shifted to HMS Ipswich (70) in March 1701 before joining HMS Mary (60) that summer. War of the Spanish Succession With the War of the Spanish Succession raging, Vernon received a promotion to lieutenant on September 16, 1702 and was transferred to HMS Lennox (80). After service with the Channel Squadron, Lennox sailed for the Mediterranean where it remained until 1704. When the ship was paid off, Vernon moved to Admiral Cloudesley Shovells flagship, HMS Barfleur (90). Serving in the Mediterranean, he experienced combat during the capture of Gibraltar and Battle of Malaga. Becoming a favorite of Shovell, Vernon followed the admiral to HMS Britannia (100) in 1705 and aided in the capture of Barcelona. Rapidly rising through the ranks, Vernon was elevated to captain on January 22, 1706 at the age of twenty-one. First assigned to HMS Dolphin (20), he shifted to HMS Rye (32) a few days later. After taking part in the failed 1707 campaign against Toulon, Vernon sailed with Shovells squadron for Britain. Nearing the British Isles, several of Shovells ships were lost in the Scilly Naval Disaster which saw four ships sunk and 1,400-2,000 men killed, including Shovell, due to a navigational error. Saved from the rocks, Vernon arrived home and received command of HMS Jersey (50) with orders to oversee the West Indies station. Member of Parliament Arriving in the Caribbean, Vernon campaigned against the Spanish and broke up an enemy naval force near Cartagena in 1710. He returned home at the wars end in 1712. Between 1715 and 1720, Vernon commanded various vessels in home waters and in the Baltic before serving as commodore at Jamaica for a year. Coming ashore in 1721, Vernon was elected to Parliament from Penryn a year later. A staunch advocate for the navy, he was vocal in debates regarding military matters. As tensions with Spain increased, Vernon returned to the fleet in 1726 and took command of HMS Grafton (70). After cruising to the Baltic, Vernon joined the fleet at Gibraltar in 1727 after Spain declared war. He remained there until fighting ended a year later. Returning to Parliament, Vernon continued to champion maritime matters and argued against continued Spanish interference with British shipping. As relations between the two countries worsened, Vernon advocated for Captain Robert Jenkins who had his ear cut off by the Spanish Coast Guard in 1731. Though wishing to avoid war, First Minister Robert Walpole ordered additional troops to be sent to Gibraltar and ordered a fleet to sail for the Caribbean. War of Jenkins War Promoted to vice admiral on July 9, 1739, Vernon was given six ships of the line and ordered to attack Spanish commerce and settlements in the Caribbean. As his fleet sailed west, Britain and Spain severed relations and the War of Jenkins Ear began. Descending on the poorly defended Spanish town of Porto Bello, Panama, he quickly captured it on November 21 and remained there for three weeks. The victory led to the naming of Portobello Road in London and public debut of the song Rule, Britannia!. For his achievement, Vernon was hailed as a hero and was granted Freedom of the City of London. Old Grog The following year saw Vernon order that the daily rum ration provided to the sailors be watered down to three parts water and one part rum in an effort to reduce drunkenness. As Vernon was known as Old Grog for his habit of wearing grogham coats, the new drink became known as grog. Some have argued that Vernon dictated the addition of citrus juice to the mixture which would led to much-reduced rates of scurvy and other diseases in his fleet as it would have added a daily dose of Vitamin C. This appears to be a misreading of his original orders and was not part of the original recipe. Failure at Cartagena In an effort to follow up Vernons success at Porto Bello, in 1741 he was given a large fleet of 186 ships and 12,000 soldiers led by Major General Thomas Wentworth. Moving against Cartagena, Colombia, British forces were hampered by frequent disagreements between the two commanders and delays ensued. Due to the prevalence of disease in the region, Vernon was skeptical of the operations success. Arriving in early March 1741, British efforts to take the city were plagued by a lack of supplies and rampaging disease. Endeavoring to defeat the Spanish, Vernon was forced to withdraw after sixty-seven days which saw around a third of his force lost to enemy fire and disease. Among those to take part in the campaign was George Washingtons brother, Lawrence, who named his plantation Mount Vernon in the admirals honor. Sailing north, Vernon captured Guantnamo Bay, Cuba and desired to move against Santiago de Cuba. This effort failed due to heavy Spanish resistance and Wentworths incompetence. With the failure of British operations in the region, both Vernon and Wentworth were recalled in 1742. A Return to Parliament Returning to Parliament, now representing Ipswich, Vernon continued to battle on behalf of the Royal Navy. Critical of the Admiralty, he may have authored several anonymous pamphlets which attacked its leadership. Despite his actions, he was promoted to admiral 1745, and took command of the North Sea Fleet in an effort to prevent French aid from reaching Charles Edward Stuart (Bonnie Prince Charlie) and the Jacobite Rebellion in Scotland. Having been refused in his request to be named Commander-in-Chief he elected to step down on December 1. The following year, with the pamphlets circulating, he was removed from the Royal Navys list of flag officers. An avid reformer, Vernon remained in Parliament and worked to improve the Royal Navys operations, protocols, and fighting instructions. Many of the changes he worked for aided in the Royal Navys dominance in the Seven Years War. Vernon continued to serve in Parliament until his death at his estate in Nacton, Suffolk on October 30, 1757. Buried at Nacton, Vernons nephew had a monument erected to his memory at Westminster Abbey.

Operation manegement (term paper) Term Paper Example | Topics and Well Written Essays - 1250 words

Operation manegement ( ) - Term Paper Example Though, services are not as fruitful for businesses and as fulfilling for customers as they could be. In addition, the business services encompass a design issue. Business professionals in the service region require recognizing that they are concerned in design as well as utilize service design to enhance it. Services have exclusive characteristics. They are not substantial, are not able to be owned or stored, utilization takes place instantly as productions as well as they are a difficult understandings that occur with the passage of time. As a result, designing services necessitates special concerns. Additionally, the service design is able to tackle the unique contests that the service financial system is experiencing. However, design is not simply crafting features of products any further. On the other hand, it is an area that designs difficult and interactive procedures, experiences as well as systems. Thus, it engages skills and professionals from the related areas and clients in the design procedures. It utilizes unique procedures, techniques and tools for service design (Mortiz, 2010). This paper presents a detailed analysis of some of the prime aspects of the service design. This paper presents a historical development in this area, after that it will analyze the companies that are applying the service design for its better assessment. ... le, a hotel can choose to encompass a service design agency transforms the means and its list of options is defined, or modify the outline of the hotel to develop customer's experience. Additionally, the customers are able to involve paying clients, however as well are able to be inside a business, on stipulation that they are the direct beneficiaries of a service. For instance a business establishes a novel payroll interface intended for its employees - so the workers are able to efficiently handle and manage 'customers' as well as payroll interface. However, to carry out this activity, service design methodologies are employed to prepare and systematize arrangement, people, and communication and material mechanism employed in a service. On the other hand, the rising significance and size of the service sector, together in terms of people engaged and financial significance necessitates services to be precisely planned sequentially for service suppliers to hang about competitive as w ell as to persist to attract diverse clients (Saco & Goncalves, 2008), (Tatum, 2010), (Shostack, 1982), (Shostack G. L., 1984) and (Mortiz, 2010). Historical Development In our daily activities we are surrounded by services. There are services those have been for us for centuries and the ancient Romans and Greek had servants and even before them those services were offered and as well paid for. Yet, we are responsive that a number of things have altered radically in the previous 25 years. In the 19th century the large industrial units, new discoveries and techniques pushed a collection of less costly commodities in the marketplace. The business revolution shaped an ocean of less costly as well as enhanced products in developed nations. Nowadays, the industrial revolution has changed society

Economic Forecasting Essay Example | Topics and Well Written Essays - 250 words

Economic Forecasting - Essay Example The telecommunication network also allows individuals in one institution to search databases, including library catalogues, in any other institution’s computer that has been made available for such use (Carnot, Koen, Tissot, & Carnot, 2011). Non-print media is also a resource that can be used in gather historical data, as well as economic forecasting data. CDs, videodisks among other resources provide large storage space for information and thus can be used to retrieve economic information stored as well as store the information being gathered. Print media such books, journals, magazines, as well as newspapers, are important resources to use while gathering economic forecasting. Books written by an economist in the past can be useful in studying the history of economic thoughts that were used in the past to help explain various economic trends (Higgins, 2011). Newspapers always have resourceful economic articles written by a knowledgeable economist. Since newspapers are produced on a daily basis, they would provide sufficient and current information that would be helpful in economic forecasting. The dialogue could also be resourceful while gathering information on the economic history of economics, as well as economic foresting. Face to face interviews with economists and other key players in the economy could complement information gathered from internet print and non-print media (Carnot et al.,

Types of Volleyball Practice Essay Example for Free

Types of Volleyball Practice Essay †¢ massed practice and distributed practice †¢ whole practice and part practice †¢ blocked practice and random practice †¢ varied and constant practice †¢ drill and problem solving Massed Practice; is a training routine in which a skill is practised continuously and consistently. E.g. 50 softball pitches, 25 basketball free throws, volleyball 40 serves. A barrier to massed practice includes fatigue and motivation and is usually undesirable to beginners. Distributed Practice; consists of short, frequent practice sessions with rest intervals. This type of practice is effective for learning skills. E.g. 5 sets of 20 chest passes with 2 minute rests. Most evidence indicates that distributed practice is more effective in improving performance. Whole Practice; is the learning of the skill in its entirety. This type of practice is effective in skills that are high in complexity and low in organisation such as jump shot or skating. Part Practice; is the learning of each of the separate components of the skill. It is particularly effective when the skill being taught is complex and has clearly defined components e.g. golf swing. Both Part and Whole Practice can be used to teach the same skills e.g. breaststroke. Blocked Practice; is where learners attempt the same skill repeatedly in order to refine and improve their performance. E.g. Tennis –15 forehands,15 backhands, 15 volleys. More effective for learners in the cognitive stage. Random Practice; is when all components of the multi task skill are practiced in random order within each practice session. Constant Practice; refers to the practice of only one skill without any variation e.g. kicking a ball to a target 10 away. Varied Practice; refers to practicing a class of skills using variations within the one practice session. E.g. kicking to a target 10m away then 20m away and 30m. Drills; Learning through repetition (eg. Dig, Set, spike drill we do in class) Problem Solving; learning through investigation and discovery.

A Patriarchal World Essay -- essays papers

A Patriarchal World John Bodnar says it well when he suggests that "the center of everyday life was to be found in the family-household. It was here that past values and present realities were reconciled, examined on an intelligible scale, evaluated and mediated." This assertion implies that the immigrant family-household is the vehicle of assimilation. I will take this assertion a step further and examine more specifically the powerful role of the patriarchal father within Anzia Yezierska's book Bread Givers and Barry Levinson's film Avalon. Yezierska's theme vividly depicts the constraint of a patriarchal world, while Levinson illustrates the process of assimilation and the immigrant, now American, family and its decline. In this paper, I will exemplify how the patriarchal father, Sam Kochinsky (Armin Mueller-Stahl) and Reb Smolinsky are the key determinant of the dynamics by which the family assimilates. In assimilation, you are said to conform to your surroundings. Assimilation is a process by which you reconcile the ideal with reality. Dealing with virtually three generations of an entire Jewish American immigrant experience, Levinson illustrates not necessarily the merging of two cultures, but possibly the tainting of authenticity, clouding (memories of) the familiar-the villain being the television. The happy community of extended family is, in the end, supplanted by the glowing idiot box that kills conversation and turns its suburban audience into zombies. In Yezierska's work, she epitomizes the struggle between the Old World and the New World. The patriarchal father, representing traditional Jewish ways, and Sara Smolinsky, the heroine, struggling against her father with the desire to reconcile with reality. In Bread Givers, Yezierska symbolically depicts Sara as the immigrant parting her ways as she embarks anew on the journey that was given to her when she arrived by which to transform her life-dealing with the daily transformation as she struggles to hold together the wants of society and her (families) authenticity in these days of deep troubles. The head of the family, Reb Smolinsky is an immovably Orthodox Jewish rabbi, who lives by the Holy Torah, and expects his family to do the same. His reign over the family reinforces Old World, traditional values and beliefs. Reb holds to the Torah belief that "if they [women] let... ...ggested an adaptation in the hopes that Jules would simply have a better life than that of a wallpaper-hanger. In putting television in place a New World, Levinson portrays how a cheap, gaudy, poor substitute somehow seduced and enraptured the family. Perhaps Levinson is saying that although it may be the easier to converge, assimilation is too costly. On the other hand, you have Reb whose stubborn beliefs and male superiority coupled with a passive wife allow him to claim control over his daughter's lives. Resentment is quite damaging and separates families as well. Either way you look at it the outlook is favorable for neither assimilation nor isolation. And so I conclude in saying that the patriarchal father has an especially important role and while he needs the strength found in Yezierska's character, Reb, (in order to hold the family together) he must also be willing to adapt to a changing reality. Immigration is neither a call for assimilation nor isolation. Indivi duality is important, but why resist change when you can better yourself in the process. Bibliography: Levinson, Barry.

Disraeli’s second ministry Essay

â€Å"Disraeli’s second ministry deserves the title a great reforming ministry† Discuss how far you agree with this view in relation to Gladstone first Ministry. A great reforming ministry is a government which manages to radically alter the political and social scene, aiming to deal with the most pressing problems and creating a long term legacy whereby later ministries aim to protect and improve what has been achieved instead of trying to alter radically. This is why it becomes clear that Gladstone ministry and not Disraeli’s should be considered a great reforming ministry. The aims of both ministries were radically different. Gladstone’s aims for his ministry when he came into power in 1867 were to try and create a more efficient and meritocratic society which removed privileges and advocated individualistic self-reliance. This ideology of beliefs were formed due to Gladstone long held religious beliefs which drove him and in the liberal ideas of equality of opportunity, tolerance and individualism he saw the best system to try and create a society based on Christian morals. Throughout all his legislation Gladstone aimed for the fair and just decision explaining his desire to try and pacify Ireland. This is in contrast to Disraeli’s aims as Prime Minister from 1874. Disraeli had managed to finally get the conservatives elected after being out of power for over ten years, and he achieved this through radically modernising the Conservative party which was represented in his Tamworth manifesto speech where he proclaimed the aims of the Conservative party were to protect institutions and traditions, strengthen the empire and alleviate the condition of the people. However Disraeli never had a clear agenda of reforms before he came into power instead his main aims were ensuring the continuation of power for the Conservative power, this meant Disraeli aimed not to disrupt his key support base of the middle and upper class and focused on reducing taxes. Additionally although due to his promise of alleviating the condition of the people he was forced to create social legislation to ensure minimal government intervention he aimed to make the acts permissive weaken their impact and focussed on areas which were non-controversial and where mild reforms could be implemented. This contrast reflects the differing impacts the two ministries wanted to achieve. Gladstone’s ministries reforms had a substantial impact. The 1870 education act with the setting up of board schools to complement the existing structure of voluntary religious schools reflect Gladstone’s desire to try and create equality of opportunity and to encourage individual self-reliance. This reform became the very foundations of the mixed school system which is present today, reflecting the long term impact this reform had. Additionally Gladstone introduced key reforms to remove privilege and create a more efficient government and army with the 1871 civil service reforms which meant entry to the civil service could only be achieved through examination and the army reforms that were carried out between 1870-1872 whereby the act of purchase was abolished and instead officer class could only be achieved through merit and amount of time privates would have to spend in the army was reduced to encourage higher uptake. This reflects the impact Gladstone was trying to achieve he didn’t shy away from attacking key sectors of power within society because he believed it was morally right and fair to remove privilege from the upper classes. This was particularity important for a working class which aimed to be free individuals who wanted the vote and an equal footing. Whilst Disraeli’s legislation although Important was hampered due to Disraeli’s desire to minimise the impact of reform and to only focus on non-controversial areas. The 1875 Artisans dwelling act is a clear example of weak legislation, the act meant that councils could compel owners of slums to sell their property and allow the council to knock-down the slums and then sell the land to private building firms. However the legislation was permissive so the council didn’t have to ensure slums were removed and it required councils to give compensation to the landowners and so by the end of Disraeli’s term the act had only been used in 10 councils making its impact very mild. Whilst other acts such as the 1875 Agriculture holdings act show Disraeli is unable to make truly effective legislation because he wishes to protect the power base of the upper class. The act should of ensured that tenants that improve their land receive compensation but Disraeli made the act permissive and stated that if there was a condition in contract which stated the landowner didn’t have to pay compensation then the landowner didn’t have too. Due to this again the impact of the legislation was minor. Other legislation shows Disraeli’s opportunistic nature and aim to keep power such as the 1875 conspiracy and protection of property act which reformed a piece of Gladstonian legislation which banned peaceful picketing this act allowed peaceful picketing which Disraeli hoped would give the Conservative support from the trade unions, to try and weaken the threat from the Liberal party. Even when Disraeli produced legislation which was aimed at alleviating the condition of the people such as the 1874 Factory Act which meant that by law women and children weren’t allowed to be made to work more than nine and half hours in a day but deliberately avoided the majority of the working population which was male and although the legislation had the impact of forcing factories to close earlier which effected male working hours as well it wasn’t the intention. Overall examining the legislation shows the difference in impact the two different ministries legislation had with Gladstone causing a huge impact whilst Disraeli’s showing only a very minor effect focusing on refining Gladstone previous legislation or reforming on very specific small issues to try and gain support. However both ministries were flawed though, for all Gladstone large and influential reforms he was voted out in 1874 and although Disraeli aimed not to lose any support he also was voted out in 1880. The reason why Gladstone was voted out were that his legislation was so wide ranging it impact on nearly every sector of society and as such Gladstone also lost his wide spectrum of support. The upper classes disliking his aims of efficiency feeling that they were breaking the traditional power structure of society against their favour. The middle and working classes were effected by Gladstone’s controversial legislation which was highly unpopular at the time such as the Licensing Act of 1872 and the 1871 Criminal Amendment Act. Both of these act reflects sometimes Gladstone misjudgement on what was beneficial for the people and how to create a fairer society. Also Gladstone failed in one of his key aims which was to pacify Ireland but he was the one of the few politicians who was truly trying to find a workable solution instead of coercion. Whilst Disraeli was voted out not because he had made a massive impact but because he was Prime Minister whilst the economy entered recession, this meant that his mild measure had even less impact and his expensive imperialistic aims were highly controversial. So due to the recession Disraeli failed to alleviate the condition of the people and his other aims meant his government appeared to stall resulting in his popularity dropping. Overall although his legislation was occasionally flawed the overall improvement and effect that Gladstone’s ministry had on the country reflect a great reforming ministry. Gladstone’s Liberal beliefs in meritocratic and individual society have become corner stones of British society reflecting the ministries long term impact and legislation such as the licensing act although unpopular at the time has only been amended never removed by later governments as they see the positive impacts of the restriction of alcohol. This reflected against Disraeli’s achievement of mildly modify Gladstone’s legislation and avoiding awkward decision domestically or trying to alter the status quo shows that his ministry cannot be considered a great reforming ministry. As such I disagree with the view that Disraeli’s government was a great reforming government instead arguing that it was his predecessor Gladstone that was clearly the great reforming ministry.

Seminar on Ubiquitous Computing

UBIQUITIOUS COMPUTING Varun. R USN- 1RE08EC110 Reva Institute of Technology and Management Bangalore. [email  protected] com Abstract- The highest ideal of ubicomp is to make a computer so imbedded, so fitting, so natural, that we use it without even thinking about it. One of the goals of ubiquitous computing is to enable devices to sense changes in their environment and to automatically adapt and act based on these changes, based on user needs and preferences.The technology required for ubiquitous computing comes in three parts: cheap, low- power computers that include equally convenient displays, a network that ties them all together, and software systems implementing ubiquitous applications. Keywords— ubicomp, nanotechnology Introduction Ubiquitous computing (often abbreviated to â€Å"ubicomp†) refers to a new genre of computing in which the computer completely permeates the life of the user. In ubiquitous computing, computers become a helpful but invisible force, assisting the user in meeting his or her needs without getting in the way.Mark Weiser, the originator of the term â€Å"ubiquitous computing†, â€Å"described it this way: â€Å"†¦ [Ubiquitous computing’s] highest ideal is to make a computer so imbedded, so fitting, so natural, that we use it without even thinking about it. † It is also referred to as Pervasive computing. Pervasive computing environments involve the interaction, coordination, and cooperation of numerous, casually accessible, and often invisible computing devices. These devices will connect via wired and wireless links to one another as well as to the global networking infrastructure to provide more relevant information and integrated services.Existing approaches to building distributed applications, including client/server computing, are ill suited to meet this challenge. They are targeted at smaller and less dynamic computing environments and lack sufficient facilities to manage changes in the network configurations. Networked computing devices will proliferate in the user’s landscape, being embedded in objects ranging from home appliances to clothing. Applications will have greater awareness of context, and thus will be able to provide more intelligent services that reduce the burden on users to direct and interact with applications.Many applications will resemble agents that carry out tasks on behalf of users by exploiting the rich sets of services available within computing environments. Our preliminary approach is to activate the world and provide hundreds of wireless computing devices per person per office, of all scales. This has required network in operating systems, user interfaces, networks, wireless, displays, and many other areas. We call our work as â€Å"ubiquitous computing†. This is different from PDA’s, dynabooks, or information at your fingertips.It is invisible; everywhere computing that does not live on a personal device of a ny sort, but is in the woodwork everywhere. Nanotechnology and Wireless Technology If computers are to be everywhere, unobtrusive, and truly helpful, they must be as small as possible and capable of communicating between themselves. Technological movements supporting these goals are already well underway under the rubrics nanotechnology and wireless computing. Nanotechnology The trend toward miniaturization of computer components down to an atomic scale is known as nanotechnology.Nanotechnology involves building highly miniaturized computers from individual atoms or molecules acting as transistors, which are the heart of the computer chip. The number of transistors in a chip is indicative of its power. Therefore, nanotechnology’s extreme miniaturization of transistors allows for impressive levels of computing power to be put into tiny packages, which can then be unobtrusively tucked away. Wireless Computing Wireless computing refers to the use of wireless technology to connec t computers to a network.Wireless computing is so attractive because it allows workers to escape the tether of a network cable and access network and communication services from anywhere within reach of a wireless network. Wireless computing has attracted enormous market interest, as witnessed by consumer demand for wireless home networks, which can be purchased for several hundred dollars. Context-Awareness and Natural Interaction Small computers that communicate wirelessly provide a necessary infrastructure for ubiquitous computing. However, infrastructure is only half of the battle.As noted above, the ubiquitous computing movement aims to make computers more helpful and easier to use. Indeed, computers should be able to accurately anticipate the user’s needs and accommodate his or her natural communication modes and styles. These themes are captured with-in the ubiquitous computing movement’s focus on context-aware computing and natural interaction. Context-Awarenes s The promise of context-awareness is that computers will be able to understand enough of a user’s current situation to offer services, resources, or information relevant to the particular context.The attributes of context to a particular situation vary widely, and may include the user’s location, current role (mother, daughter, office manager, soccer coach, etc. ), past activity, and affective state. Beyond the user, context may include the current date and time, and other objects and people in the environment. The application of context may include any combination of these elements. For example, a context-aware map might use the information that the user is away from home, has no appointments, and that the time is 6:00 in the evening to determine that the user could soon be interested in dinner.It would then prepare to offer the user guidance to nearby restaurants should he or she makes such a request. Natural Interaction Currently, using the computer is part of the task we are attempting to accomplish—something else to focus on, learn, or do in order to accomplish a goal. The idea behind natural interaction is for the computer to supply services, resources, or information to a user without the user having to think about the rules of how to use the computer to get them. In this way, the user is not preoccupied with the dual tasks of using the computer and getting the services, resources, or information.Donald Norman, a well-known researcher in human–computer interaction, once said that he doesn’t want a word processor; he wants a letter writer—something that will allow him to get the job done of writing a letter, without the instrument getting in the way. UbiquiTrain The UbiquiTrain system is based on a database of training content to which users connect via desktop computers and wireless handheld systems. UbiquiTrain loads training content according to an algorithm that includes a number of context-related cues. The first cue centers on the user’s schedule.For example, if there is an upcoming meeting called by the user, UbiquiTrain would load training content on how to lead meetings. As the meeting time approaches, this training content floats to the top of the list of topics available. A second cue invokes the context of the user’s current activities. If the user is working on a task related to an item on his or her to-do list, UbiquiTrain would load corresponding content, as well. For example, the user working on a proposal would cue UbiquiTrain to call up training content on written communication in general and proposal writing in particular.UbiquiTrain holds content at the ready should users ask for it. The system does not demand the user’s attention. As befits the nature of ubiquitous computing, users interact with UbiquiTrain in the way that feels most natural to them. Some users talk to the system, asking it to show them a particular piece of training content. Other s, not yet comfortable with talking to a computer, use the touch screen. UbiquiTrain reacts to the user, as well. Noting the confusion on the user’s face as it explains how to deal with attendees who derail meetings, for example UbiquiTrain tries explaining the concept a different way.It then offers a short video example. Observing that the user is nodding, UbiquiTrain resumes the normal course of training. Of course, if users are looking for information on a particular topic, they can skip straight to the content simply by asking for it. UbiquiTrain is flexible enough to understand the different ways users might request a given piece of content. UbiquiTrain is more than a means to deliver already-developed training content. The system also offers important benefits in training needs assessment by monitoring trends in training content demands across users.The system takes action when it senses a trend in demand for certain broad areas of training content among members of part icular departments or among workers with similar duties across different departments. As a means of respecting user’s privacy, the system polls them and asks if they would like to request in-depth training on the topic, taking suggestions for areas in which users might want particular detail. If sufficient interest is found, the results are then forwarded to the group responsible for training in the organization. By observing trends in content demand, UbiquiTrain can also sense when its database is incomplete.If users ask for content that doesn’t exist in the database, the request is logged. If a sufficient number of similar requests are received, the system generates a requisition for new content. In this way, the database stays current with the needs of its users. Finally, UbiquiTrain can help evaluate the training it has delivered. The most overt way is to ask the user for feedback on the training received. A second way is have the user request relevant coworkers to evaluate him or her in a given area at a given time, if appropriate. The rating task, of course, is administered by UbiquiTrain through the coworkers’ computers or handhelds.Raters can choose to make their ratings and comments anonymous, if they wish. Once all of the data are compiled, UbiquiTrain feeds them back to the user and offers appropriate development suggestions. The system makes use of the data, as well, to track the effectiveness of the training it has delivered. Clearly, UbiquiTrain offers important benefits to all constituents. Users have a convenient, up-to-date training tool that unobtrusively responds to their needs. At the corporate level, the training needs within the organization are easily tracked and clearly delineated and can be analyzed to fine detail. Current Embedded TechnologyEmbedded technology is the process of introducing computing power to various appliances. These devices are intended to perform certain specific jobs and processors giving the c omputing power are designed in an application oriented way. Computers are hidden in numerous information appliances which we use in our day to- day life. These devices find there application in every segment of life such as consumer electronics, avionics, biomedical engineering, manufacturing, process control, industrial, communication, defence etc†¦ Embedded systems, based on there functionality and performance requirement are basically categorized as: i.Stand alone systems ii. Real time systems iii. Networked systems iv. Mobile devices Stand alone systems work in stand alone mode, taking inputs and producing desired outputs. They do not have any dependence on other systems. Embedded systems in which some specific work has to be done in a specific time period are called Real time systems. Meeting the dead line is the most important requirement of a real time system. In Hard real time systems, missing a deadline may lead to a atastrophe and in Soft real time systems such proble m is not present.Systems which are provided with network interfaces and accessed by networks such as LAN or the Internet are called Networked Systems. Networking may be wired or wireless. Mobile devices are devices which move from one location to another, like mobile phones, PDA’S etc. Today, many people carry numerous portable devices, such as laptops, mobile phones, PDAs and mp3 players, for use in their professional and private lives. For the most part, these devices are used separately i. e. , their applications do not interact.However, if they could interact directly, participants at a meeting could share documents or presentations, business cards would automatically find their way into the address register on a laptop and the number register on a mobile phone, as commuters exit a train, their laptops could remain online; likewise, incoming email could now be diverted to their PDAs. In such a distributed environment where several embedded devices has to communicate and c o-ordinate with each other. For this a communication link is required which may be wired or wireless.In initial stages of Networked embedded system environments wired connection was preferred as it provided a safer and faster channel for communication. But the cost, immovability and the cables running around the floorboards became less attractive. On top of this, dishing out the cash for network cards, cables and a hub/switch reserved this practice to the more elite computer users, until wireless networking hit the scene. Infrared communication was initially used for wireless communication because of the low cost offered by it. But it suffered from the limitation that it can be used only within Line Of Sight. IEEE introduced 802. 1 as the international standard for wireless LANs. This used a 2. 4GHz transmission band while maintaining a steady 1-2 Mbps bandwidth rate. Being that this was extremely slow compared to 100Mbit wired LANs, it took a while for the 802. 11 standard to devel op into a viable solution, achieved shortly after with the 802. 11a, b and g standards, offering bandwidth ranging from 11Mbps to 54Mbps. Although this is still considerably short of the 100Mbit found in cabled networks, 802. 1 x wireless technologies is now literally regarded as the future of networking. Bluetooth, Wi-Fi, Wi-Max are the latest solutions, under the 802. x standard, for wireless communication over short, medium and long range communication respectively. Pervasive Computing Earlier in this paper, we characterized a pervasive computing environment as one saturated with computing and communication capability, yet so gracefully integrated with users that it becomes a ‘‘technology that disappears. ’’ Since motion is an integral part of everyday life, such a technology must support mobility; otherwise, a user will be acutely aware of the technology by its absence when he moves. Hence, the research agenda of pervasive computing subsumes that of mob ile computing, but goes much further.Specifically, pervasive computing incorporates four additional research thrusts into its agenda, as illustrated by Figure 1. Effective Use of Smart Spaces The first research thrust is the effective use of smart spaces. A space may be an enclosed area such as a meeting room or corridor, or it may be a well-defined open area such as a courtyard or a quadrangle. By embedding computing infrastructure in building infrastructure, a smart space brings together two worlds that have been disjoint until now [16]. The fusion of these worlds enables sensing and control of one world by the other.A simple example of this is the automatic adjustment of heating, cooling and lighting levels in a room based on an occupant’s electronic profile. Influence in the other direction is also possible — software on a user’s computer may behave differently depending on where the user is currently located. Smartness may also extend to individual objects, whether located in a smart space or not. Invisibility The second thrust is invisibility. The ideal expressed by Weiser is complete disappearance of pervasive computing technology from a user’s consciousness. In practice, a reasonable approximation to this ideal is minimal user distraction.If a pervasive computing environment continuously meets user expectations and rarely presents him with surprises, it allows him to interact almost at a subconscious level [46]. At the same time, a modicum of anticipation may be essential to avoiding a large unpleasant surprise later — much as pain alerts a person to a potentially serious future problem in a normally-unnoticed body part. Localized Scalability The third research thrust is localized scalability. As smart spaces grow in sophistication, the intensity of interactions between a user’s personal computing space and his surroundings increases.This has severe bandwidth, energy and distraction implications for a wireless mobile user. The presence of multiple users will further complicate this problem. Scalability, in the broadest sense, is thus a critical problem in pervasive computing. Previous work on scalability has typically ignored physical distance — a web server or file server should handle as many clients as possible, regardless of whether they are located next door or across the country. The situation is very different in pervasive computing.Here, the density of interactions has to fall off as one moves away — otherwise both the user and his computing system will be overwhelmed by distant interactions that are of little relevance. Although a mobile user far from home will still generate some distant interactions with sites relevant to him, the preponderance of his interactions will be local. Like the inverse square laws of nature, good system design has to achieve scalability by severely reducing interactions between distant entities. This directly contradicts the current etho s of the Internet, which many believe heralds the ‘‘death of distance. ’’Masking Uneven Conditioning The fourth thrust is the development of techniques for masking uneven conditioning of environments. The rate of penetration of pervasive computing technology into the infrastructure will vary considerably depending on many non-technical factors such as organizational structure, economics and business models. Uniform penetration, if it is ever achieved, is many years or decades away. In the interim, there will persist huge differences in the ‘‘smartness’’ of different environments — what is available in a well-equipped conference room, office, or classroom may be more sophisticated than in other locations.This large dynamic range of ‘‘smartness’’ can be jarring to a user, detracting from the goal of making pervasive computing technology invisible. One way to reduce the amount of variation seen by a us er is to have his personal computing space compensate for ‘‘dumb’’ environments. As a trivial example, a system that is capable of disconnected operation is able to mask the absence of wireless coverage in its environment. Complete invisibility may be impossible, but reduced variability is well within our reach. [pic]This figure shows how research problems in pervasive computing relate to those in mobile computing and distributed systems. New problems are encountered as one move from left to right in this figure. In addition, the solution of many previously-encountered problems becomes more complex. As the modulation symbols suggest, this increase in complexity is multiplicative rather than additive — it is very much more difficult to design and implement a pervasive computing system than a simple distributed system of comparable robustness and maturity. Note that this figure describes logical relationships, not temporal ones.Although the evolution o f research effort over time has loosely followed this picture, there have been cases where research effort on some aspect of pervasive computing began relatively early. For example, work on smart spaces began in the early 1990’s and proceeded relatively independently of work in mobile computing. Figure 1: Taxonomy of Computer Systems Research Problems in Pervasive Computing Example Scenarios What would it be like to live in a world with pervasive computing? To help convey the ‘‘look and feel’’ of such a world, we sketch two hypothetical scenarios below.We have deliberately chosen scenarios that appear feasible in just a few years. These examples use Aura as the pervasive computing system, but the concepts illustrated are of broad relevance. Scenario 1 Jane is at Gate 23 in the Pittsburgh airport, waiting for her connecting flight. She has edited many large documents, and would like to use her wireless connection to e-mail them. Unfortunately, bandwid th is miserable because many passengers at Gates 22 and 23 are surfing the web. Aura observes that at the current bandwidth Jane won’t be able tofinish sending her documents before her flight departs.Consulting the airport’s network weather service and flight schedule service, Aura discovers that wireless bandwidth is excellent at Gate 15, and that there are no departing or arriving flights at nearby gates for half an hour. A dialog box pops up on Jane’s screen suggesting that she go to Gate 15, which is only three minutes away. It also asks her to prioritize her e-mail, so that the most critical messages are transmitted first. Jane accepts Aura’s advice and walks to Gate 15. She watches CNN on the TV there until Aura informs her that it is close to being done with her messages, and that she can start walking back.The last message is transmitted during her walk, and she is back at Gate 23 in time for her boarding call. Scenario 2 Fred is in his office, fr antically preparing for a meeting at which he will give a presentation and a software demonstration. The meeting room is a ten-minute walk across campus. It is time to leave, but Fred is not quite ready. He grabs his PalmXXII wireless handheld computer and walks out of the door. Aura transfers the state of his work from his desktop to his handheld, and allows him to make his final edits using voice commands during his walk. Aura infers where Fred is going from his calendar and the campus location racking service. It downloads the presentation and the demonstration software to the projection computer, and warms up the projector. Fred finishes his edits just before he enters the meeting room. As he walks in, Aura transfers his final changes to the projection computer. As the presentation proceeds, Fred is about to display a slide with highly sensitive budget information. Aura senses that this might be a mistake: the room’s face detection and recognition capability indicates tha t there are some unfamiliar faces present. It therefore warns Fred. Realizing that Aura is right, Fred skips the slide.He moves on to other topics and ends on a high note, leaving the audience impressed by his polished presentation. Missing Capabilities These scenarios embody many key ideas in pervasive computing. Scenario 1 shows the importance of pro activity: Jane is able to complete her e-mail transmission only because Aura had the foresight to estimate how long the whole process would take. She is able to begin walking back to her departure gate before transmission completes because Aura looks ahead on her behalf. The scenario also shows the importance of combining knowledge from different layers of the system.Wireless congestion is a low-level system phenomenon; knowledge of boarding time is an application or user-level concept. Only by combining these disparate pieces of knowledge can Aura help Jane. The scenario also shows the value of a smart space. Aura is able to obtain k nowledge of wireless conditions at other gates, flight arrival/departure times and gates, and distance between gates only because the environment provides these services. Scenario 2 illustrates the ability to move execution state effortlessly across diverse platforms — from a desktop to a handheld machine, and from the handheld to the projection computer.Self-tuning, or automatically adjusting behavior to fit circumstances, is shown by the ability to edit on the handheld using speech input rather than keyboard and mouse. The scenario embodies many instances of pro activity: inferring that Fred is headed for the room across campus, warming up the projector, transferring the presentation and demonstration, anticipating that the budget slide might be displayed next, and sensing danger by combining this knowledge with the inferred presence of strangers in the oom. The value of smart spaces is shown in many ways: the location tracking and online calendar services are what enable A ura to infer where Fred is heading; the software-controlled projector enables warm up ahead of time; the camera-equipped room with continuous face recognition is key to warning Fred about the privacy violation he is about to commit. Perhaps the biggest surprise in these scenarios is how simple and basic all the component technologies are.The hardware technologies (laptops, handhelds, wireless communication, software-controlled appliances, room cameras, and so on) are all here today. The component software technologies have also been demonstrated: location tracking, face recognition, speech recognition, online calendars, and so on. Why then do these scenarios seem like science fiction rather than reality today? The answer lies in the fact that the whole is much greater than the sum of its parts. In other words, the real research is in the seamless integration of component technologies into a system like Aura.The difficult problems lie in architecture, component synthesis and system-l evel engineering. Difference between traditional networking and pervasive computing These connections are fundamentally unlike those we associate with networks. Rather than using the network to connect computers that are being used directly by people, these appliances communicate over networks such that people do not directly monitor the communication between machines and programs.The majority of these communications will occur in an end-to-end structure that does not include a human at any point. The number of machines connected to the Internet has been increasing at an exponential rate and will continue to grow at this rate as the existing networks of embedded computers, including those that already exist within our automobiles, are connected to the larger, global network, and as new networks of embedded devices are constructed in our homes and offices.The kinds of devices that will be used to access the Internet are no longer confined to desktops and servers, but include small de vices with limited user interface facilities (such as cell phones and PDAs); wireless devices with limited bandwidth, computing power, and electrical power; and embedded processors with severe limitations on the amount of memory and computing power available to them. Many of these devices are mobile, changing not only geographic position, but also their place in the topology of the network. Unlike traditional Desktop Computers and existing networks, the new devices will have the following characteristics: 1.Many will have small, inexpensive processors with limited memory and little or no persistent storage. 2. They will connect to other computing elements without the direct intervention of users. 3. Often, they will be connected by wireless networks. 4. They will change rapidly, sometimes by being mobile, sometimes by going on and offline at widely varying rates. Over time, they will be replaced (or fail) far more rapidly than is now common. 5. They will be used as a source of infor mation, often sending that information into the center of the network to which they are attached.Ubi-Finger Here, in contrast, Ubi-Finger is the gesture-i/p device, which is simple, compact and optimized for mobile use. Using our systems, a user can detect a target device by pointing with his/her index finger, and then control it flexibly by performing natural gestures of fingers (Fig. 1). [pic][pic][pic] | | | | |By pointing a light and making| |The light will turn on! | |a gesture like â€Å"push a | | | |switch†. | | |Figure- 1 An example to control Home Appliances | [pic] Figure- 2 As shown in fig. 2, ubi-finger consists of three sensors to detect gestures of fingers, an infrared transmitter to select a target device in real world and a microcomputer to control these sensors and communicate with a host computer. each sensor generates the information of motions as follows: (1) a bending degree of the index finger, (2) tilt angles of the wrist, (3) operations of touch senso rs by a thumb.We use (1) and (2) for recognition of gestures, and use (3) for the trigger mechanism to start and stop gesture recognitition. Information Hoppers and Smart Posters Once these zones are setup, computers on the network will have some interesting capabilities. The system will help to store and retrieve data in an Information hopper. This is a timeline of information that keeps track of when data is created. The hopper knows who created it, where they were and who they were with. Another application that will come out of this ultrasonic location system is the smart poster.A convention computer interface requires us to click on a button on your computer screen. In this new system, a button can be placed anywhere in your workplace, not just on the computer display. The idea behind smart posters is that a button can be a piece of paper that is printed out and struck on a wall. Smart posters will be used to control any device that is plugged into the network. The poster will know where to send a file and a user’s preferences. Smart posters could also be used in advertising new services.To press a button on a smart poster, a user will simply place his or her bat in the smart poster button and click the bat. The system automatically knows who is pressing the poster’s button. Posters can be created with several buttons on it. Ultrasonic location systems will require us to think outside of the box. Traditionally, we have used our files, and we may back up these files on a network server. This ubiquitous network will enable all computers in a building to transfer ownership and store all our files in a central timeline. HAVi- An Implementation in Consumer Appliance EnvironmentHAVi is a standard for home appliances consisting of a set of APIs, services, and a standard for communication. HAVi’s primary goal is providing a dynamic service environment in which software components can discover and interact with other. It provides mechanisms fo r devices to discover, query and control other appliances on the home network, and provides system services such as message and event. Eight major consumer electronics manufacturers have come up with an open standard enabling home entertainment devices to communicate intelligently with each other.The HAVi(Home Audio Video Interoperability) standard promises to bring true platform independent interoperability to consumer devices using high bandwidth IEEE 1394 (FireWire) as the connecting medium. Major consumer electronics, software, semiconductor and computer manufacturers, namely Grundig, Hitachi, Panasonic, Philips, Sharp, Sony, Thomson and Toshiba along with now over 30 other participants, have formed a non-profit organization called HAVi (Home Audio Video Interoperability) for promoting the development of interoperable consumer products.The goal of HAVi organization is to provide a standard open architecture for intelligent audio and video devices to interoperate with each other regardless of manufacturer, operating system, CPU or programming language used for implementation. The simplest example can be time synchronization between different devices. TV set might get the correct time from the broadcast stream and the other devices can query the TV and set their own clocks according to it. Setting the VCR to record a program is a familiar situation users usually have problems with.With HAVi enabled devices this task can be made very easy. User can select the program he wishes to record with the Electronic Program Guide (EPG) residing on a digital TV set (or set top- box). The TV then locates an available recorder (e. g. , a VCR or a recording DVD device) and commands it to record the program supplying it with the time, length and channel parameters taken from the EPG. Thus, the user doesn’t need to program or touch the recording device in any way. The advantages of Pervasive Computing:We increasingly rely on the electronic creation, storage, and trans mittal of personal, financial, and other confidential information, and demand the highest security for all these transactions and require complete access to time-sensitive data, regardless of physical location. We expect devices — personal digital assistants, mobile phones, office PCs and home entertainment systems — to access that information and work together in one seamless, integrated system. Pervasive computing gives us the tools to manage information quickly, efficiently, and effortlessly.It aims to enable people to accomplish an increasing number of personal and professional transactions using a new class of intelligent and portable appliances or â€Å"smart devices† embedded with microprocessors that allow users to plug into intelligent networks and gain direct, simple, and secure access to both relevant information and services.. It gives people convenient access to relevant information stored on powerful networks, allowing them to easily take action an ywhere, anytime.Pervasive computing simplifies life by combining open standards-based applications with everyday activities. It removes the complexity of new technologies, enables us to be more efficient in our work and leaves us more leisure time and thus pervasive computing is fast becoming a part of everyday life. Concerns The power ubiquitous computing promises carries with it significant risks. One such risk is associated with the amount of privacy that must be sacrificed to see the benefits of truly helpful computers.Another is that early, â€Å"bleeding edge† applications of ubiquitous computing will turn out to be more ambitious than effective, leading some to prematurely conclude that the idea is a failure. We address each of these concerns below. Privacy Issues Simply put the more software tracks users, the more opportunities exist to trample on their right to privacy. To some degree, these issues are already being argued in the contexts of corporate e-mail snooping and the use of IT software that can track user activity down to the level of individual keystrokes.However, factoring in the idea of software that can track and act upon a user’s physical presence and form of activity leads to privacy concerns of a magnitude beyond those currently debated. The privacy implications of ubiquitous computing implementations must always be accorded the most careful consideration. Without powerful standards surrounding user privacy, the future world of ubiquitous computing may very well shift from one of ease and convenience to one where each of us has an inescapable sense of being watched, at best, and no control over our personal information, at worst.Such prospects are clearly far from desirable. Growing Pains Systems that can act as subtly as those described will not come without a substantial developer learning curve. As system developers learn from their mistakes, there will undoubtedly be at least one premature declaration that truly ubiqui tous computing is an impractical ideal and that the interim efforts are too riddled with problems to be usable. We cannot guarantee that ubiquitous computing will fulfill its promise. However, we would argue that it ought to do so, based on the strong trend we have observed toward more powerful, more usable software.The first author recalls a word processor from about 1984 that required the manual entry of printer codes for boldface and italic fonts. Advanced ideas like templates and styles—and, come to think of it, tables—were far from consideration as features. Modern word processors are very powerful, flexible, and easy to use compared to anything that has come before. Usability is definitely a recognized goal in software design, and much has been learned to make new software—even unique, new applications—very easy to use.It should only get better. Ongoing Research: A number of leading technological organizations are exploring pervasive computing. Xero x's Palo Alto Research Center (PARC), for example, has been working on pervasive computing applications since the 1980s. Although new technologies are emerging, the most crucial objective is not, necessarily, to develop new technologies. IBM's project Planet Blue, for example, is largely focused on finding ways to integrate existing technologies with a wireless infrastructure.Carnegie Mellon University's Human Computer Interaction Institute (HCII) is working on similar research in their Project Aura, whose stated goal is â€Å"to provide each user with an invisible halo of computing and information services that persists regardless of location. † The Massachusetts Institute of Technology (MIT) has a project called Oxygen. MIT named their project after that substance because they envision a future of ubiquitous computing devices as freely available and easily accessible as oxygen is today.What is this next generation going to look like? Today the uses of Internet are limited a s its users look for read-mostly information. As we move to a world where the Internet is used as an infrastructure for embedded computing, all this will change. We can hypothesize that the individual utility of mobile communication, wireless appliances and the respective mobile services – pervasive technologies in general – will be exploited through a digital environment that is – †¢ aware of their presence sensitive, adaptive and responsive to their needs, habits and emotions †¢ and ubiquitously accessible via natural interaction. Increasingly, many of the chips around us will sense their environment in rudimentary but effective ways. For Example – ? Cell phones will ask the landline phone what its telephone number is and will forward our calls to it. ? Remote computers will monitor our health statistics and will determine when one is in trouble and will take appropriate action for rescue. Amplifiers will be implanted and used in the inner ear . ? New machines that scan, probe, penetrate and enhance our bodies will be used. ? Refrigerators will be connected to the Internet so one could find out, via cell phone or PDA, what is in it while one is at the store. A refrigerator may even sense when it is low on milk and order more directly from the supplier or rather than this, the connection will enable the manufacturer to monitor the appliance directly to ensure that it is working correctly and inform the owner when it is not. Stoves will conspire with the refrigerators to decide what recipe makes the best use of the available ingredients, and then guide us through preparation of the recipe with the aid of a network-connected food processor and blender. Or they will communicate to optimize the energy usage in our households. ? Cars will use the Internet to find an open parking space or the nearest vegetarian restaurant for their owners or to allow the manufacturer to diagnose problems before they happen, and either inform the owner of the needed service or automatically install the necessary (software) repair. Wrist watches will monitor our sugar. [pic] ? Digi-tickers or implanted heart monitors in heart patients will talk wirelssly to computers, which will be trained to keep an eye open for abnormalities. [pic] In a nutshell, our personal network will travel around with us like a surrounding bubble, connecting to the environment through which we move and allowing our mobile tools to provide us with more functionality than they ever could alone. Conclusion: Pervasive computing provides an attractive vision for the future of computing.Well, we no longer will be sitting down in front of a PC to get access to information. In this wireless world we will have instant access to the information and services that we will want to access with devices, such as Smartphones, PDAs, set-top boxes, embedded intelligence in your automobile and others, all linked to the network, allowing us to connect anytime, anywhere s eamlessly, and very importantly, transparently. Computational power will be available everywhere through mobile and stationary devices that will dynamically connect and coordinate to smoothly help users in accomplishing their tasks.We are heading toward a reality that plays like a scene from Star Trek. We may have difficulty envisioning these possibilities, but they are not remote anymore. Technology is rapidly finding its way into every aspect of our lives. Whether it’s how we shop, how we get from one place to another or how we communicate, technology is clearly woven into the way we live. Indeed, we are hurtling â€Å"towards pervasive computing†. When Edison finally found a filament that would burn, did he see the possibility of silent but pervasive electrical current flowing throughout our homes, cars and communities?An easy way to comply with the conference paper formatting requirements is to use this document as a template and simply type your text into it.

lasswells model of communicat essays

lasswell's model of communicat essays An Evaluation of the 2004 Philippine Election Campaign Using Lasswells Model of Communication Comparing the recent Philippine election with the past ones, one would notice the great dependence on media during the campaign of the candidates in the recent race. It seems that most candidates really knew the extent of medias influence in the outcome of the elections. Moreover, the results of the election further indicate how much media plays a part in our decisions for our country. Harold Lasswells communication model can be used to evaluate this recent event and see why some candidates prevailed and others did not. The first stage of Lasswells model, Who, seeks to explain who is in control. It would be reasonable to argue that those who were in control in the campaign period were those who won seats in the government. In relation to George Gerbners model, those who were in control were those who had access to the media. During the campaign period, TV audiences were bombarded with political advertisements, of which candidates spent millions for, especially during prime time. Because of this expensive way of campaigning, we can conclude that riches played a great part in the recent elections. Money was one way of gaining access to the media in order to reach people of different sectors. Their frequent appearances have helped them gain recognition. Gloria Macapagal-Arroyo reportedly spent P333 million while Fernando Poe Jr. used up 92.1 million. Noli de Castro was said to have spent P89.6 million while his main vice presidential rival, Loren Legarda spent P64.9 million. Another VP candidate, Herminio Aquino declared in his statement of expenditures and contributions a total of P6.58 million, way below compared to that of the other two other candidates expense. Among the senatorial bets, Manuel Mar Roxas, the candidate with the most vote...

Linguistic Typology

Linguistic Typology Linguistic Typology is the analysis, comparison, and classification of languages according to their common structural features and forms. This is also called cross-linguistic typology.   The branch of linguistics that studies the structural similarities between languages, regardless of their history, as part of an attempt to establish a satisfactory classification, or typology, of languages is known as typological linguistics (Dictionary of Linguistics and Phonetics, 2008). Examples   Typology is the study of linguistic systems and recurring patterns of linguistic systems. Universals are typological generalizations based on these recurring patterns.Linguistic typology took off in its modern form with the ground-breaking research of Joseph Greenberg, such as, for example, his seminal paper on a cross-linguistic survey of word order leading to a series of implicational universals (Greenberg 1963). . . . Greenberg also attempted to establish methods for quantifying typological studies, in order that linguistic typology could meet scientific standards (cf. Greenberg 1960 [1954]). Furthermore, Greenberg re-introduced the importance of studying the ways languages change, but with the emphasis that language changes give us possible explanations for language universals (cf., for example, Greenberg 1978).Since Greenbergs pioneering efforts linguistic typology has grown exponentially and is, as any science, continuously being enhanced and redefined as to methods and approac hes. The last few decades have seen the compilation of large-scale databases with the help of ever more refined technology, which have led to new insights as well as given rise to new methodological issues.(Viveka Velupillai, An Introduction to Linguistic Typology. John Benjamins, 2013) Tasks of Linguistic Typology Among the tasks of general linguistic typology we include . . . a) the classification of languages, i.e., the construction of a system to order natural languages on the basis of their overall similarity; b) the discovery of the mechanism of construction of languages, i.e., the construction of a system of relationships, a network by means of which not only the obvious, categorial mechanisms of language can be read but also the latent ones.(G. Altmann and W. Lehfeldt, Allgemeinge Sprachtypologie: Prinzipien und Messverfahren, 1973; quoted by Paolo Ramat in Linguistic Typology. Walter de Gruyter, 1987) Fruitful Typological Classifications: Word Order In principle, we might pick on any structural feature and use it as the basis of classification. For example, we could divide languages into those in which the word for a canine animal is [dog] and those in which it isnt. (The first group here would contain exactly two known languages: English and the Australian language Mbabaram.) But such a classification would be pointless since it wouldnt lead anywhere.The only typological classifications which are of interest are those which are fruitful. By this, we mean that the languages in each category should turn out to have other features in common, features which are not used to set up the classification in the first place.[The most celebrated and fruitful of all typological classifications has proved to be one in terms of basic word order. Proposed by Joseph Greenberg in 1963 and more recently developed by John Hawkins and others, word-order typology has revealed a number of striking and previously unsuspected correlations. For example, a language with SOV [Subject, Object, Verb] order is highly likely to have modifiers that precede their head nouns, auxiliaries that follow their main verbs, postpositions instead of prepositions, and a rich case system for nouns. A VSO [Verb, Subject, Object] language, in contrast, usually has modifiers that follow their nouns, auxiliaries that precede their verbs, prepositions, and no cases.(R.L. Trask, Language, and Linguistics: The Key Concepts, 2nd ed., edited by Peter Stockwell. Routledge, 2007) Typology and Universals [T]ypology and universals research are intimately related: if we have a set of significant parameters whose values none the less show a high degree of correlation, then the network of relations among these parameter values can equally be expressed in the form of a network of implicational universals (absolute or tendencies).Clearly, the more widespread the net of logically independent parameters that can be linked in this way, the more significant is the typological base being used.(Bernard Comrie, Language Universals, and Linguistic Typology: Syntax and Morphology, 2nd ed. The University of Chicago Press, 1989) Typology and Dialectology There is evidence from linguistic varieties around the world, including Greek dialects, to suggest that the distribution of structural characteristics over the worlds languages may not be entirely random from a sociolinguistic point of view. For example, we have seen indications that long-term contact involving child bi-lingualism may lead to increased complexity, including redundancy. Conversely, contact involving adult second language acquisition may lead to increased simplification. Furthermore, communities with dense, tightly-knit social networks may be more likely to demonstrate fast-speech phenomena and the consequences of this, and more likely to experience unusual sound changes. I would like to suggest, moreover, that insights of this type can complement research in linguistic typology by giving an explanatory edge to the findings of this discipline. And I would also suggest that these insights should give some sense of urgency to typological research: if it is true that cert ain types of linguistic structure are to be found more frequently, or possibly only, in dialects spoken in smaller and more isolated communities, then we had better research these types of communities as rapidly as we can while they still exist.

Literary Research Paper Essay Example | Topics and Well Written Essays - 1750 words

Literary Research Paper - Essay Example ions of the Soviet Union, the chaos and violence that occur as a result have long-lasting, often life or death, consequences for those who have taken part (Stern, 1975). Although racial tensions between the Turks and the Cypriots have always proven difficult to manage, which is highlighted in the short story â€Å"Gregory† written by Panos Ioannides in 1963, the choices made by the individuals within the short story serve to indicate that these tensions might not have reached such violent proportions had a few different choices been made on either side. The short story itself is simple enough to summarize. A narrator soldier tells his thoughts and feelings as he follows his orders and performs his duty. The tension involved in this job is revealed from the beginning lines of the story, â€Å"My hand was sweating as I held the pistol. The curve of the trigger was biting against my finger† (648). Although he has obviously held a pistol before, the concept that his hand is sweating around it indicates that either he is in a very warm climate or the presence of the pistol is creating a strong conflict within the man holding it. That the latter interpretation is probably correct is immediately reinforced by the idea that the trigger was ‘biting’ against his finger, fighting against him, injuring him and making him decidedly uncomfortable. The task he faces is made difficult not only because his orders are to execute another man, difficult enough in itself, but also because the man he is ordered to execute is an innoc ent, a friend and a man who had saved the narrator’s life only a few days earlier. In trying to relate the difficulty of the task in front of him, the narrator illustrates the various aspects of both his own life as the unit’s designated executioner and what that has done to his own psyche, but also the aspects of Gregory’s life that make it so difficult for the narrator to squeeze the trigger. Most of these attributes were brought about

The Impact of Stress on Workers Essay Example | Topics and Well Written Essays - 1000 words

The Impact of Stress on Workers - Essay Example The arrival of stress, in the same way, is directly related to excessive work or persistent boredom which can be observed so very often in any workplace’s environment fraught with an unchanging aura. What makes the work-related stress a serious and hazardous issue is the worst kind of depression it can lead a worker to and profoundly impact his/her life. Therefore, it can be said that though stress itself may not be called a disease, but the consequential problems it gives birth to become worth addressing once they mature into gravely complicated issues like physical unfitness and psychological disorders. Relentless work pressures and increased competitiveness: Given the unbelievably quick rise observed in industrialism and materialistic public approach in the recent years, this would not be hyperbolical to state that work pressures both on the employers and employees have increased proportionately. That is the same reason why so much research has been done on the influence th is work pressure produces on the workers to the point that â€Å"one in 20 cases of depression or anxiety annually is attributable to high stress at work† (NHS, 2007). ... No sooner do the helpless workers exposed to insane work pressures come out of one complex problem, does another fall down on their heaving shoulders. Recurring headaches, angry cramps in the neck and back especially, distorted thinking, terrible memory, sleeping difficulties, and dark hopelessness are just some of the deplorable physical and mental consequences produced by work stress on the workers as identified by (Workers Health Centre, 2005). Emotional turmoil and layoff fear induced by work stress: Work stress is justifiably proved to be a powerful and influential emotional roller for workers around the globe, as a result of excessive competitiveness and unpredictable employment opportunities. It remains undeniable that competitiveness has peaked in the present age in all employing firms and fear of layoff is what keeps haunting the workers persistently, which leads them to work more and more in order to keep their employers happy and escape the looming prospect of unemployment . All this pandemonium created by work-related stress induces the workers to go into realm of bizarre fantasy and some may even opt to find solace by engaging themselves in a hedonistic lifestyle, thus deviating from the right path and hitting the perturbed one, all the while influenced by that same cursed work-related stress. Recent research consolidates the hazardous consequences produced by excessive work pressures by bringing up the fact that â€Å"regardless of occupation, seniority, or salary level, we’re spending more and more of our work days feeling frazzled and out of control, instead of alert and relaxed† (Segal, Smith, Robinson, & Segal, 2011). Disorientation is one of the most powerful influences which grips the workers as soon
