In grid environment, resources and users from different administrative domains are integrated and coordinated each other. Grid uses open standard, general-purpose protocols and interfaces to provide nontrivial quality of services. Videoconferencing is communication between two or more people from geographically different locations by simultaneous two-way video and audio transmissions. This is a...

The privacy of personal information on the Internet has become a major concern for governments, businesses, media, and the public. Platform for Privacy Preferences (P3P), developed by the World Wide Web Consortium (W3C), is the most significant effort underway to enable web users to gain more control over their private information. P3P provides mechanisms for a web site to encode its data-colle...

This paper will review the device physics governing the operation of the industry standard ETOX flash memory cell and show how it is ideally suited for multiple bit per cell storage, through its storage of electrons on an electrically isolated floating gate and through its direct access to the memory cell. The device and reliability physics aspects of the three key technology features of multip...

Researchers have often been confronted with contradictory reactions to the implementation of a new technology within a single setting. For example, Walsham (2002) documents a technology transfer case that resulted in a variety of contradictory reactions including partial acceptance, outright resistance, and conflict, all within the same organization. The literature documents numerous situations...

Purpose – One of the critical issues for change management, particularly in relation to the implementation of new technologies, is the existence of prior knowledge and established mental models which may hinder change efforts. Understanding unlearning and how it might assist during organizational change is a way to address this resistance. The purpose of this paper is to present research design...

CORDIC algorithms have long been used in digital signal processing for calculating trigonometric, hyperbolic, logarithmic and other transcendental functions. The algorithm requires only shift and add operations and this simplicity encourages its implementation in hardware. Traditional CORDIC architectures have focused on radix-2 implementations because of their higher accuracy. However these ar...

This paper looks at the mutual interplay between information technology (IT) and its environment. Exploring specifically the issues surrounding innovations in the field of corporate IT systems we show that a distinction has to be made between different categories of information technology (IT) systems regarding their introduction, subsequent diffusion, and particularly their corporate usage. We...

As the important implementation of biometric technology, palmprint verification is one of the most reliable personal identification methods. In this paper, a new approach to palmprint verification based on line feature matching and datum point invariance is presented. The datum points of palmprint, which act as the important registrations, are defined owing to their remarkable advantage of inva...
