This seminar presents a feasibility study for performing virtual address translation without specialized translation hardware. Removing address translation hardware and instead managing translation in software has the potential to make the processor design simpler, smaller, and more energy-efficient at little or no cost in performance.

The purpose of this seminar is to describe the design and quantify its performance impact. Trace-driven simulations show that software managed address translation is just as efficient as hardware managed tran ....etc

Rapid change is under way on sever fronts I medicine and surgery. Advance in computing power have enable continued growth in virtual reality, visualization, and simulation technologies. The ideal learning opportunities afforded by simulated and virtual environments have prompted their exploration as learning modalities for surgical education and training. Ongoing improvements in this technology suggest an important future role for virtual reality and simulation in medicine.


Medical virtual reality has come a long way in the past 10 y ....etc

The rapid progress of internet-based networking technologies enables a remote access to engineering lab-oratory equipment and instruments. Since control engineering education should combine theory with practice, this feature can be especially useful to provide students with an Internet access to various experimental setups located in control laboratories. This paper discusses the various concepts related to development of remote accessible control laboratory with the help of the concept of virtual instrumentation. This also looks in detail to ....etc

ABSTRACT:- In the autumn of 1969, we decided to try a new approach to the design of a virtual machine operating system. Until that time, most installations using Virtual Machine Monitors merely ran operating systems that already existed for €œstand-alon use. Few, if any, installations had attempted to design and create an operating system that took advantage of its running environment. The Virtual Machine Monitor we were using was a highly modified version of CP-67 which was designed to operate on an IBM S/360 Model ....etc

VPNs have emerged as the key technology for achieving security over the Internet. While a VPN is an inherently simple concept, early VPN solutions were geared towards large organizations and their implementation required extensive technical expertise. As a consequence, small and medium-sized businesses were left out of the e-revolution. Recently, VPN solutions have become available that focus specifically on the needs of small and medium-sized businesses. Historically, the term VPN has also been used in contexts other than the Inter ....etc

Controlling and Assisting Activities in Social Virtual Worlds
1. Introduction
Since its beginning, web technology has advanced from a text-based to a visual-based
interaction. This evolution has been facilitated by both high speed internet connections and
PC's graphical power. Virtual world (VW) technology began as standalone applications
(e.g.. virtual simulations) but soon evolved into web-based applications. Nowadays, home
users for entertainment and wide-spread enterprises or institutions for business can ex ....etc

Based on internet technology, intranets are becoming an essential part of corporate information systems today. However, internets were not originally designed with businesses in mind. It lacks the technology required for secure business transactions and communications. A challenge therefore arises for businesses with intranet, i.e. how to establish and maintain trust in an environment which was originally designed for open access to information. More specifically, a way has to be found to secure an intranet without impinging on its ....etc

Abstract

In this paper we present a multimodal interface for navigating in arbitrary virtual VRML worlds. Conventional haptic devices like keyboard, mouse, joystick and touchscreen can freely be combined with special Virtual-Reality hardware like spacemouse, data glove and position tracker. As a key feature, the system additionally provides intuitive input by command and natural speech utterances as well as dynamic head and hand g ....etc

A mobile virtual reality service (VRS) will make the presence and presentation of the sounds and sights of an actual physical environment virtually available everywhere in real time through the use of mobile telecommunication devices and networks. Furthermore, the VRS is the conversion of a physical system into its digital representation in a three-dimension (3D) multimedia format. This paper addresses one aspect of the notion of bringing an actual multimedia environment to its virtual presence everywhere in real time .

An inte ....etc

Virtual Reality (VR),
system that enables one or more users to move and react in a computer-simulated environment. Various types of devices allow users to sense and manipulate virtual objects much as they would real objects.

This natural style of interaction gives participants the feeling of being immersed in the simulated world.

Virtual worlds are created by mathematical models and computer programs. ....etc
