The performance demands of new systems are forcing new approaches to solving complex power management problems. Solutions will require a system approach where portions of the power management circuitry will exist in the form of traditional separate chips and portions will be literally embedded with the system chips themselves. This paper will explore two such high performance systems, multi-GHz...

Content-based image retrieval is a fairly new discipline. Yet research in this field has highlighted many approaches that show good performance in specific subproblems using single filtering criteria, such as color based histograms, shape description or texture analysis. Most systems built so far use multiple access methods although they compose them according to a pre-defined strategy. In this...

Internet and Web technology already penetrates many aspects of our daily life and its importance as a medium for business transactions will grow exponentially during the next years. B2B market places provide new kinds of services to their clients. Simple 1-1 connections are being replaced by n-m relationships between customers and vendors. However, this new flexibility in electronic trading als...

A model of the hippocampus is presented which forms rapid self -organized representations of input arriving via the perforant path, performs recall of previous associations in region CA3, and performs comparison of this recall with afferent input in region CA 1. This comparison drives feedback regulation of cholinergic modulation to set appropriate dynamics for learning of new representations i...

Information quality (IQ) plays a critical role in ecommerce consumers’ purchase decisions, and product-related user-generated content (PUGC) is an increasingly important source of information. Nevertheless, vendors currently do not take full advantage of PUGC since PUGC is mainly used for evaluation purposes. Integrating PUGC into earlier phases of the purchase-decision process might be promisi...

Balancing regional and national electronic health record (EHR) approaches requires cooperation between clinical and technical experts at different organisational levels. Bridging is necessary to achieve interoperability between regional EHR systems, without neglecting the clinical usefulness. This study has investigated the approaches chosen in modelling the clinical content of EHRs in two out ...

The possible interactions among tourism organizations, their customers and other organizations are considered in this article. Based on these interactions, three drivers of an integrated e-business strategy in the tourism sector are suggested: (1) customizing tourist products, personalizing services and supporting mobile services, (2) sharing tourism information and operational data, and (3) of...

In this paper the architecture of a mobile network messaging system where Multimedia Messages (MMS) can be sent to a web page or application for creation of content by users is investigated. The currently specified architecture of MMS is evaluated and it is shown that the IP data based nature of the service makes it ideal for user created content services. The billing and charging issues for MM...
