In this study, the capabilities of an IEEE 802.11 wireless LAN are measured. For the test phases, three wireless laptop computers, a wireless and wired desktop computers and an access point (AP) are used. In addition to these computers, products of Lucent Technologies have been used as the wireless communication adapters. Our metric that is the criteria used to evaluate the performance of our W...

Lecture slides are commonly used in university to support teaching and learning. An effective way to organize and access slides will enhance the education quality. This paper presents a software system that allows instructors to index slides for student search and enquiry. The web-based system can be accessed with multiple channels of wireless handheld devices and wired desktop and laptop compu...

Most relatively modern desktop or even laptop computers contain a graphics card useful for more than showing colors on a screen. In this paper, we make a case for why you should learn enough about GPU (graphics processing unit) computing to use as an accelerator or even replacement to your CPU code. We include an example of our own as a case study to show what can be realistically expected.

Eighty-four students distributed between two different courses at a major research university (one a communication course, the other a computer science course) were given laptop computers with wireless network access during the course of a semester. Awide variety of data (from questionnaires, e-mail logs, proxy server logs, and diaries) regarding students’ use of the laptops for electronic comm...

An eight-channel surface stimulation system, designed for paraplegic stepping was adapted for paraplegic cycling on a newly developed tricycle. The stimulation system consists of two four-channel modules an Inter Integrated Bus (I2C) to RS232 interface for direct stimulator control and data exchange and a standard laptop computer. A software package for personal computers with a comfortable gra...

Users who operate in the field (e.g., maintenance personnel, geologists, archaeologists, tourists, first responders) bring often with them paper sheets (e.g., city maps, forms, technical plans, object descriptions) containing data needed for their activities. Even when this data is available in digital form, the mobile condition of these users makes them prefer more portable and manageable solu...

Loop scheduling on parallel and distributed systems has been thoroughly investigated in the past. However, none of them considers the feature of multicore architecture dominating the current markets of desktop computers, laptop computers, servers, etc. On the other hand, although there have been many studies proposed to employ the hybrid MPI and OpenMP programming model to exploit different lev...

Global active noise control has been obtained on the tonal noise from a small centrifugal blower, similar to those used in laptop computers. Compact control systems were investigated for two configurations. The blower was mounted in both a short rectangular duct and in a mock laptop case that was modeled as a two-dimensional rectangular enclosure. Secondary sources and error sensors were locate...

The demand and use of mobile phones, PDAs and smart phones are constantly on the rise as such, manufacturers of these devices are improving the technology and usability of these devices constantly. Due to the handy shape and size these devices come in, their processing capabilities and functionalities, they are preferred by many over the conventional desktop or laptop computers. Mobile devices ...

Many schools and educational institutions are using wireless Wi-Fi and Tablet technologies in their education. Recently WHO IARC classified radiofrequency (RF) radiation ‘possibly carcinogenic to humans’. Currently guidance levels for electromagnetic fields (including RF) are based on thermal effects while effects have been reported on non-thermal levels. Possibly these biological, non-thermal ...
