oday, as data sets used in computations grow in size and complexity, the technologies developed over the years to deal with scientific data sets have become less efficient and effective. Many frequently used operations , such as Eigenvector computation, could quickly exhaust our desktop workstations once the data size reaches certain limits. On the other hand, the high-dimensional data sets we ...

T oday the average health care consumer gets more health and medical information from the Internet than from his or her own physician.' As the t ime consumers spend in actual conversation with doctors shrinks, they are turning increasingly to the Web—and expecting their physicians to follow them. In fact, main' consumers have become so attached to the Web, they are wil l ing to change physician...

In this paper, field measurements from the GSM and UMTS networks are analysed in a road traffic information context. The measurements indicate a p otentially large improvement using UMTS signalling data compared to GSM regard ing handover location accuracy. These improvements can be used to generate real-time traffic information with higher quality and extend the geographic usage area for cellu...

T oday, few firms could survive for very long without their computer systems. IT has permeated every corner of firms. Firms have reached the current state in their use of IT because IT has provided myriad opportunities for firms to improve performance and, firms have availed themselves of these opportunities. Some have argued, however, that the opportunities for firms to improve their performan...

T ODAY, MOTION CONTROL TECHNIQUE is utilized in many industrial systems such as machine tools, industrial robots, positioning stages, material handling systems, electric transportation, disk drives, rolling mills, printers, film molding machines, etc. Since performance of Motion Control system employed in such machines affects their all-out performance, advances in Motion Control system are imp...

ODAY, high resolution analog to digital converters (ADC) are often used for precision measurements of voltage and current. The measurement uncertainty of the RMS value of the analog sinusoidal signal depends on the quality of the ADC and on the algorithms used for RMS estimation. This paper will focus only on the algorithms for RMS estimation of the sinusoidal signal. The comparison of classica...

oday, not a few university rectors are conscious their inadequacy to deal with the complex situation of higher education. I join the group, but my courage to put some educational thoughts on paper derives from the fact that I am kept on my rectorial toes by the impact of a young, dynamic university. I hope to be able to share my worries with the vanishing race of non-gowned university members w...

due to the extensive research in the emerging field of ontologies. Ontologies Driven Information Systems (ODIS) were introduced by N. Guarino in 1998 [Gua98], and recently is finding rather a great attention from numerous, diversified fields such as Web-based information systems, information integration, and the Semantic Web. This paper introduces the notion of contextual ontologies which it ca...

enabled access to up-to-date surgical materials. However, we oday, the medical degree certificate only gives new graduaes a permit to continue studying and improving themselves, ince it is impossible, over the six years of the course, to resent students with the vast amounts of material that make p the various medical specialties. This completion of training is done in a variety of ways and y a...

T oday, important information is scattered in so many places, formats, and media, that getting the right information at the right time and place is an extremely difficult task. Developing a single software product, for example, includes the creation of documents ranging from the requirements specification and project schedules to marketing presentations , multimedia tutorials, and more. Each do...
