conclusions the study results are indicative of the impact of electromagnetic fields on computer users’ health, and it is thus advisable to avoid leaving computers switched on unnecessarily in addition to observing the minimum distance of 60 cm from computer monitors to control the adverse effects of electromagnetic fields. materials and methods electric and magnetic field intensities were meas...

The academic world is at the beginning of a major shift in the library computing paradigm. Librarians have participated in the movement from paper-based systems to mainframe computing. This was followed by the movement to personal computing based on ever more sophisticated and powerful personal computers. In the past few years we have begun to see the development of the use of portable laptop c...

BACKGROUND Survey data are traditionally collected using pen-and-paper, with double data entry, comparison of entries and reconciliation of discrepancies before data cleaning can commence. We used Personal Digital Assistants (PDAs) for data entry at the point of collection, to save time and enhance the quality of data in a survey of over 21,000 scattered rural households in southern Tanzania. ...

When it comes to making of certain decisions everyday/routine or specific, which often imply planning, programming, selection the most favorable alternative, financing realization business task, is mostly based on data analysis. Criteria are imposed that occasion diverse and sometimes mutually opposed. Problems posed decision maker unstructured so there no mathematical algorithm for solving the...

This demo will showcase LifeJoin, a system that collects raw sensor data from phones and laptop computers to generate interesting events. Given the raw sensor data, LifeJoin implements a number of activity recognition algorithms to generate higher-level events. Furthermore, it uses supervised learning techniques to learn from users’ feedback to generate only events of interest. In this demo, th...

Erythema ab igne is a pigmented reticular skin lesion with telangiectasias caused by prolonged exposure to heat. This report describes the case of a 12-year-old adolescent girl with erythema ab igne induced by a laptop computer. The paper also discusses how computers generate heat and how important it is for the manufacturers of these devices to warn consumers of the potential hazards that coul...

Palmtop computers which consume very little power, have very small size, and are much cheaper compared to their laptop counterparts are proliferating in the market. However, there exist no satisfactory wireless connectivity solution in terms of cost and power consumption to connect these devices to the network. This paper describes a cost-effective, low-power wireless connectivity solution for ...

Mobile 1 computer usage is increasing rapidly and laptops now come equipped with the latest microprocessors, color displays, large disks and other energy-intensive devices. Unfortunately, the batteries that power all this portability are lagging behind in their ability to meet these increasing power requirements. As a result mobile computers suuer from short battery life and require frequent re...

It has been suggested that exposure to heavy school backpacks is a relatively recent phenomenon. Factors such as reduced use of student lockers secondary to security concerns, an increased use of laptop computers, and increased carrying of non-educational loads such as musical instruments and sports equipment have potentially increased student exposure to heavy load carriage. It is therefore pl...
