Under pressure to keep spending down but also keep pace with rapid technology changes, many districts are future-proofing their schools--trying to get the most out of tech spending by providing solutions they can use now and in the future without major, expensive infrastructure overhauls. In the Folsom Cordova (California) Unified School District,…

With the projected higher demand for Network Systems Analysts and increasing computer crime, network security specialists are an organization's first line of defense. The principle function of this paper is to provide the evolution of Collegiate Cyber Defense Competitions (CCDC), event planning required, soliciting sponsors, recruiting personnel…

Teaching a computer security course which includes network administration and protection software is especially challenging because textbook tools are out of date by the time the text is published. In an effort to use lab activities that work effectively, we turned to the internet. This paper describes several resources for teaching computer…

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,…

The Service Oriented Computing (SOC) paradigm, defines services as software artifacts whose implementations are separated from their specifications. Application developers rely on services to simplify the design, reduce the development time and cost. Within the SOC paradigm, different Service Oriented Architectures (SOAs) have been developed.…

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…

Network technology provides access to various sources of information from across the world. Network technology allows the higher education system to bring the lab to the classroom, rather than making students move to separate classrooms when they need to use computers. It, therefore, saves cost and makes students more productive. Students and…

Student engagement--it's what every educator strives for. When a lesson includes showing a movie and involving students in a discussion about it, it's even harder to get--and keep--students engaged. What if there was a free, easy way to engage one's students during lessons like this, meeting them "where they live" with technology, effortlessly…

The work presented here demonstrates the feasibility of using the single-mode fibers of an optical Internet network to deliver visible light between separate laboratories as a way to perform remote spectroscopy in the visible for teaching purposes. The coupling of a broadband light source into the single-mode fiber (SMF) and the characterization…

People live in an era of social, enterprise-oriented, and increasingly cloud-based technology; a dramatic shift away from stand-alone isolated silos that previously dominated. Computing systems can flourish today only when built to easily exchange data and services. An application that stands alone may provide practical functionality but may not…

Laboratory experience is a key factor in technical and scientific education. Virtual laboratories have been proposed to reduce cost and simplify maintenance of lab facilities while still providing students with access to real systems. It is important to determine if such virtual labs are still effective for student learning. In the assessment of a…

The word "wisdom" is rarely seen in contemporary technology and learning discourse. This conceptual paper aims to provide some clear principles that answer the question: How can we establish wisdom in complex learning networks? By considering the nature of contemporary calls for wisdom the paper provides a metatheoretial framework to evaluate the…

The use of radio frequency identification (RFID) technology is increasingly common. Its use for specific applications has been mandated by a number of major retailers, as well as by the U.S. government; however, core RFID technologies and networks lack consistent approaches to maximize the efficiency and security of RFID applications. The purpose…

Ethnographic and interview data from a long-term study of "NetU," a wired community and college, are used to investigate the effects of computer-mediated communication on social relationships. During the course of this research "LAN" residents of NetU are compared with a similar group of non-LAN residents who lived in the same neighborhood, but…

Education facilities managers are faced with a daunting set of challenges: They must find new ways to reduce energy consumption and carry out greener energy policies. HVAC typically accounts for more than 30% of a building's electricity costs, so there is a clear incentive to eliminate unnecessary heating and cooling of unoccupied rooms. With more…
