Wearable computers

Wearable computing facilitates a new form of human--computer interaction comprising a small body--worn computer (e.g. user--programmable device) that is always on and always ready and accessible. In this regard, the new computational framework differs from that of hand held devices, laptop computers and personal digital assistants (PDAs). The ``always ready'' capability leads to a new form of synergy between human and computer, characterized by long-term adaptation through constancy of user--interface. What is a wearable computer A wearable computer is a computer that is subsumed into the personal space of the user, controlled by the user, and has both operational and interactional constancy, i.e. is always on and always accessible. Most notably, it is a device that is always with the user, and into which the user can always enter commands and execute a set of such entered commands, and in which the user can do so while walking around or doing other activities. The most salient aspect of computers, in general, (whether wearable or not) is their {\em reconfigurability} and their {\em generality}, e.g. that their function can be made to vary widely, depending on the instructions provided for program execution. With the wearable computer (WearComp), this is no exception, e.g. the wearable computer is more than just a wristwatch or regular eyeglasses: it has the full

History of Computer Architecture and Operating System.

History of Computer Architecture and Operating System Humans do not have the ability to solve all problems, and even if they do, not as fast as a computer can do. A digital computer is a machine that follows algorithms written by humans. Following an algorithm means solving a problem by carrying out instructions of how to solve it. The earliest electronic digital computers were launched in the 1940s. These machines had no operating system. The programs had to be entered one bit at a time on rows of mechanical switches. The language programs of the machine were entered on punch cards, and the programming process were speed by developing the assembly languages. The first Operating System was implemented in 1950s by the General Motors Research Laboratories. The systems were called single - stream batch processing systems because the programs and data submitted were in groups or batches. An Operating System is the software that controls the hardware. The hardware includes processors, storage, Input/Output devices, communications devices and data. Hardware only specify the physical devices that a computer uses to accomplish a task, provides computer power, but cannot use it. To make the power that the hardware provides useful, an Operating System is needed because it makes this power usable. Operating System, which are resource managers, manage the computer hardware and

IT at the Table.

PART A Have to use Nolan's Growth Model PART B IT at the Table Involving the IS professional in the merger and acquisition team early is essential. During initial meetings between the two entities, many of the general legal and business issues discussed could have potentially devastating effects on information system scope and design development. Being present to determine the language of the acquiring or ceding company is important for the IS executives. Items as mundane as provider networks can become cumbersome during implementation if one company's definition of a provider network differs from the other's. Clearly defining operational terms during the early stages helps IS executives incorporate them into a commonly understood scope document. The resulting design document will reflect a more realistic timeline and personnel estimate to be included in the overall economic analysis of the new formation. Information system assessment procedures greatly enhance the probability of a successful implementation. The need to integrate new systems quickly can be an extremely difficult task for a number of reasons: . Corporate planning does not always include IS personnel in the planning process. In addition, IS integration - related planning typically does not occur until the merger is over, thus delaying the process (Stylianou et.al., 1999). 2. The new corporate

What is the meaning of p<0.05?

Deakin University Faculty of Health and Behavioural Sciences School of Psychology What is the meaning of p<0.05? Jessica Jacques Submitted as an assessment for Research Methods C (HPS 742) Due Date: Tuesday 26th April 2005 Word Count: 1, 497 Hypothesis testing based on statistical significance has dominated behavioural and social science graduate programs for over 40 years and as a current psychology student I can promise you it still does (Huberty, 1996). A closer review of the history and current status of our beloved significance tests and their computed p value, revealed to me that one can probably say that few methodological issues in social science research have generated as much controversy. In fact as Anderson, Burnham, & Thompson (2000) note, across the years and throughout disciplines, the frequency of published criticisms has grown substantially. However before the feeling of the rug being pulled from underneath overwhelms me, one must ask the question what in fact is the meaning of the p value such as 0.05? Put more precisely what is being tested and where does it fit into data analysis and research if at all? This essay will unravel what exactly is tested by statistical significance tests, the role of replicability to the progression of scientific knowledge, significance testing based on the falsificationist approach to science and the topic of effect

Computational Linguistics.

Computational Linguistics Brian Junker Computational linguistics is a highly advanced and up-to-date profession. The occupation, around for nearly sixty years, has focused on many things, including machine translation and other types of natural language computer processing. Today, computational linguists pilot forward new technologies, allowing humans to more effectively communicate with machines as well as other people. Straight out of high school, linguists must begin on an extremely rigorous academic preparation. A four-year Bachelor of the Arts degree in college and a Ph. D. in graduate school are essential. The job serves as a bridge between the typically academic career of a linguist and that of a computer scientist. The combination yields high salaries, interesting workplaces and a bright future. In 1946, first endeavors were made at using computers to process human speech. During the cold war, when there was much tension between the United States and the Union of Soviet Socialist Republics, each country wanted to find a quick, non-man-requiring way to translate one language to the other (Baucher). Computers seemed a viable tool; however, when these machine translation systems became active, their performance was far under the expectation. Thus, computational linguistics, the science of perfecting these and other natural language processing systems, was born (Ball).

How do people contribute to the catastrophic breakdown of complex automated technologies?

How do people contribute to the catastrophic breakdown of complex automated technologies? As scientific knowledge progresses and technological advances are made, greater dependence is placed upon automated systems and their complexities are, necessarily, increased. Whilst the systems themselves may be rigorously tested to ensure they operate correctly, errors can enter the system via the weak link in the chain - the human designers and operators. Unlike the machines that they operate, humans are not very good at doing the same task for a prolonged period, or at doing two things at once, and their performance becomes impaired if asked to do so, e.g. Casali & Wierewith 1984. Human errors therefore become almost an inevitability in a complex system and this has lead to much research into the causal factors behind errors and new ways of implementation to minimise their occurrence. Reason (1990) distinguishes between two types of error; latent errors, problems caused by poor design or implementation at a high level which may not be immediately apparent, and active errors, errors caused by front line operators which are often inherited from latent errors, although the consequences here are usually seen on site and are more immediately apparent. Latent errors are the more serious category for complex automated systems as they may not be apparent at the initial onset of system
