The XO computer is a rugged, low power, low cost laptop intended for educating children aged 6-12 in developing countries. One Laptop per Child, a non-profit programme originally created at Massachusetts Institute of Technology in America, distributes them to governments of developing countries that are committed to funding and supporting its programme to enable learning through collaboration, ...

An ad-hoc network is the cooperative engagement of a collection of (typically wireless) mobile nodes without the required intervention of any centralized access point or existing infrastructure. To provide optimal communication ability, a routing protocol for such a dynamic self-starting network must be capable of unicast, broadcast , and multicast. In this paper we extend Ad-hoc On-Demand Dist...

The relevance of this article can be described by the rapid development in computer technology which has resulted in widespread use of laptop computers. Consequently the population is now more exposed to the electromagnetic fields, emanating from such devices. The aim of this article is to test various intervention measures which would help to reduce the exposure. The authors focus only on the ...

BACKGROUND Scrotal hyperthermia has been identified as a risk factor for male infertility. Laptop computers (LC) have become part of a contemporary lifestyle and have gained popularity among the younger population of reproductive age. LC are known to reach high internal operating temperatures. We evaluated the thermal effect of LC on the scrotum. METHODS Right and left scrotal temperature (Sc...

This paper introduces the OWL stage effects pedal and aims to present the device within the context of Human Computer Interaction (HCI) research. The OWL is a dedicated, programmable audio device designed to provide an alternative to the use of laptop computers for bespoke audio processing on stage for music performance. By creating a software framework that allows the user to program their own...

Wireless networks are very common, both for organizations and individuals. Many laptop computers have wireless cards pre-installed for the buyer. The ability to enter a network while mobile has great benefits. However, wireless networking has many security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into non-wireless net...

As a systems administrator on call at any time of day, I want to explore ways to manage the environment and handle emergencies remotely. In this paper, I look at a number of options for remote administration using compact devices. While the most obvious form of remote administration is a laptop computer, not every organization has the budget to provide these to their systems administrators. Als...

The majority of today’s college students enter their first computer science course with a working knowledge of computers, primarily PC/Windows based. Their experience with PC systems as their “native language” is then reinforced in the many universities that require laptop PCs or distribute them to incoming freshmen. Teaching students the Unix environment thus has become more difficult as stude...

T HIS ARTICLE provides an overview of the successful laptop implementation in the College of Education at the University of South Florida (USF). The pilot initiative began with one cohort of preservice teachers in 2003; since then, the program has expanded throughout the college. Through a chronological outline of the issues, formative evaluations, modifications, and expansion of the project as...
