... the design considerations for a private video on demand implementation. INTRODUCTION The Initiative for Worldwide Multimedia Teleconferencing and Video Server Standards The market for multipoint multimedia teleconferencing and video server equipment is poised for explosive growth. The technology for this necessary and much- anticipated business tool has been in development for years. By the turn of the century, teleconferences that include any combination of video, audio, data, and graphics will be standard business practice. Compliance with teleconferencing standards will create compatible solutions from competing manufacturers, feeding the market with ...
... large drawings using mylars would cease to be, thus helping provide a paper less environment. Another improvement as a result of CAD would be that of achieving much tighter tolerances in building new products. Using a CAD system, part designs could be received in an electronic format such as a math model. These models are currently in use by customers such as GM, BMW and Mercedes. The effect of having math models of all new products would enable a quicker turnaround in both quoting and production of products. CAD Vendors & Hardware Suppliers: Upon observing the various systems used by several customers and suppliers, the major CAD vendors worth consideration ...
... set an impressive performance standard with its pipelined, superscalar microarchitecture. The Pentium processor's pipelined implementation uses five stages to extract high throughput from the silicon - the Pentium Pro processor moves to a decoupled, 12-stage, superpipelined implementation, trading less work per pipestage for more stages. The Pentium Pro processor reduced its pipestage time by 33 percent, compared with a Pentium processor, which means the Pentium Pro processor can have a 33% higher clock speed than a Pentium processor and still be equally easy to produce from a semiconductor manufacturing process (i.e., transistor speed) perspective. The Pent ...
... making a wise purchase decision. A computer has only one purpose; to run programs. Some programs require more computing power than others. In order to figure out how powerful a computer the consumer needs, therefore, a person must first determine which programs he wants to run. For many buyers, this creates a problem. They cannot buy a computer until they know what they want to do with it, but they cannot really know all of the uses there are for a computer until they own one. This problem is not as tough as it seems, however. The consumer should go to his local computer store, and look at the software that's available. Most programs explain their minimum hardwa ...
... even used to design and build faster and build faster computers. Computers can be classified as analog or digital. Both types process data, but in different ways. Analog computers are best suited to solving problems in which several quantities vary continuously over a period of time, making exact answers difficult or impossible to obtain. Digital computers are capable of providing exact answers to problems. The basic concept of a computer is very simple. A computer processes step by step, performing one operation at a time. For example, a computer reads a number from memory, stores it, reads another number from memory, stores it, retrieves the first number, adds it ...
... during the cold war in 1969. It was developed by the US Department of Defense's (DOD) research people in conjunction with a number of military contractors and universities to explore the possibility of a communication network that could survive a nuclear attack. It continued simply because the DOD, DOD's contractors, and the universities found that it provided a very convenient way to communicate (Wendell). The ARPANET was a success from the very beginning. Although originally designed to allow scientists to share data and access remote computers, e-mail quickly becomes the most popular application. The ARPANET became a high-speed digital post-office as people ...
... general pattern for the wireless link is as follows. Physical layer An RF carrier signal that is digitally modulated to create a bit stream. This bit stream incorporates forward error correction, interleaving and other techniques to mitigate the effects of interference and weak signals that can produce high-bit-error rates. Link layer Usually a specialized radio protocol that employs a form of medium access optimized for the radio environment. Most link protocols involve interactions between the wireless modem and a base station, and mobile units do not communicate directly with each other. Network layer Some wireless WANs, such as RAM Mobile Data and A ...
... where the pilot's fixation is, it mage there. The technology to make this possible was developed by a research team headed by Professor Richard Frecker and Professor Moshe Eizenman. The work was carried out in collaboration with CAE Electronics Ltd. of Montreal with financial support from the Natural Sciences and Engineering Research Council of Canada. Their eye-tracker can record and analyze accurately up to 500 eye positions per second. The system works by means of capturing and processing the reflections of a low-level beam o f invisible infra-red light shone onto the eye. Multi-element arrays capture the image of the eye and digitize the ...
... though of late they are becoming more aggressive. Computer Criminals tend to usually be "between the ages of 14-30, they are usually bright, eager, highly motivated, adventuresome, and willing to accept technical challenges."(Shannon, 16:2) "It is tempting to liken computer criminals to other criminals, ascribing characteristics somehow different from 'normal' individuals, but that is not the case."(Sharp, 18:3) It is believed that the computer criminal "often marches to the same drum as the potential victim but follows and unanticipated path."(Blumenthal, 1:2) There is no actual profile of a computer criminal because they range from young teens to elders, ...
... by the computer simulation program or database driving the creation of the scene. Thus the visual quality of a VR experience is dependent on the speed of both the graphics-rendering hardware/software and the computer system itself. (Gump) There are four major types of devices currently in use: the head-mounted display (HMD), the binocular omni-oriented monitor (BOOM), the workstation "desktop" model (DEERING), and the projection model (CAVE). The HMD is a tracked helmet worn by the user that provides small television screens properly placed in front of the eyes. Although modest in comparison with other VR devices, it is not lightweight enough to prevent fatig ...
