In this paper, an educational methodology based on collaborative and competitive learning is proposed. The suggested approach has been successfully applied to an undergraduate communication networks course, which is part of the core curriculum of the three-year degree in telecommunications engineering at the University of Valladolid in Spain. This…

The nation's critical infrastructure, information systems, and telecommunication networks are vulnerable and threatened by an ever-growing number of attacks in cyberspace. An essential element of the nation's comprehensive approach to cybersecurity is the ability for the Department of Defense to protect and defend its information enterprise.…

The remarkable development in ICT (Information and Communication Technology) was observed in the past decades that it has an increasing impact on economic and social activities in the world. ICT have had a significant role in the economic growth for developed and developing countries. The countries have been very dynamic in recent years in East…

This dissertation deals with a multiterminal source model for secret key generation by multiple network terminals with prior and privileged access to a set of correlated signals complemented by public discussion among themselves. Emphasis is placed on a characterization of secret key capacity, i.e., the largest rate of an achievable secret key,…

Pervasive computing is an emerging concept that thoroughly brings computing devices and the consequent technology into people's daily life and activities. Most of these computing devices are very small, sometimes even "invisible", and often embedded into the objects surrounding people. In addition, these devices usually are not isolated, but…

The correlation between ICT-supported education system and economic development of a developing country has been documented by several studies (Anderson, 2009; Selwood et al, 2003; and Unwin, 2009). Today's Information and Communication Technology can significantly and positively impact the educational and economic landscape of the Democratic…

Language immersion from birth is crucial to a child's language development. However, language immersion can be particularly challenging for hearing parents of deaf children to provide as they may have to overcome many difficulties while learning sign language. We intend to create a mobile device-based system to help hearing parents learn sign…

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity for lighting an LED. No battery or complex circuitry is required. The device can form the basis of a range of interesting experiments on the physics and technology of mobile phones. (Contains 5 figures.)

Purpose: The purpose of this paper is to describe and analyse what retail and hospitality industry employers want from training and trainers. Design/methodology/approach: The research project was undertaken for Service Skills Australia, the Australian Industry Skills Council that oversees formal training for a range of service industries in…

"Necessity is the mother of invention," as the saying goes, and in this case, it surely was. A telecommuting faculty for a Midwest public university wanted to see a graduate student's presentation as a guest speaker in an instructional technology course on campus. However, this faculty lives in another state, so that was impossible. As a daily…

For thousands of years before the invention of reliable clocks, humans measured their days by the motion of the sun. Astronomically, one day was the length of time it took for the sun to return to the same position in the sky. With the advent of precise mechanical chronometers such as Harrison's timekeepers (Sobel and Andrewes 1998), which ran at…

Analysis of survey data from 995 undergraduates at a large southeastern university revealed that 93% reported owning a cell phone and a statistically significant difference between women and men (95% versus 91.2%) and between Whites (95.1%) and Blacks (87.7%). In addition, Blacks were twice as likely as Whites to be bothered by their partner's use…

Printed books are losing out to digital resources, bringing profound change to school libraries while provoking a fierce debate over the very act of reading. This article discusses what James Tracy, the headmaster of Cushing Academy, a prep school about 90 minutes west of Boston, did. He began to rid the campus library of virtually all of its…

In this paper, an innovative educational approach to introducing undergraduates to both digital signal processing (DSP) and field programmable gate array (FPGA)-based design in a one-semester course and laboratory is described. While both DSP and FPGA-based courses are currently present in different curricula, this integrated approach reduces the…

This paper presents findings from a survey that sought the post-treatment support preferences of a group of outpatient alcohol and other drug treatment clients. The client group (n = 83) were presented with six possible models of post-treatment support and were asked to express their level of interest in using or receiving each model and, if…
