This chapter introduces a new radio resource management technique based on distributed dynamic channel assignment, and sharing load among Access Points (AP). Deploying wireless LANs (WLAN) at large scale is mainly affected by reliability, availability, fairness, scalability, and performance. These parameters will be a concern for most of managers who wanted to deploy WLANs. In order to address ...

Due to business innovation and IT, information systems (IS) are made up of distributed autonomous subsystems running on heterogeneous IT platforms. These subsystems implement differently same business objects and processes. Thus pieces of data and processes are overlapping and replicated. Moreover, informational and computational resources are locked i.e. they do exist, but they are not accessi...

PURPOSE To evaluate currently available, no-cost, Web-based patient support resources designed for those who have recently undergone ostomy surgery. DESIGN Descriptive, correlational study using telephone survey. SAMPLE AND SETTING The sample comprised 202 adults who had ostomy surgery within the previous 24 months in 1 of 5 hospitals within a large healthcare organization in the Midwestern...

The advancements of technology have led to the use of electronic reading systems for digital text. Research indicates similarities and differences in reading performance and comprehension in digital formats compared to paper formats. This study compared vocabulary understanding and reading comprehension scores from two reading sources (electronic story book and paper-based book). This study als...

Knowledge management intrinsically involves communication and information sharing, which can be strongly affected by the context in which it is viewed and interpreted. This situation gets worst when complex domains are considered, as it is the case of the Construction Industry domains. The development of ontologies to unify and to put into context the different concepts and terms of the sometim...

The number of available DSS within organizational Intranets will soon require efficient retrieval functionality. While Web retrieval technology performs excellent on documents, computational services need approaches that capture the semantics of resources. We present a retrieval approach that uses a variant of Structured Modeling to represent resources. It allows the use of similarity of models...

BACKGROUND A study about healthcare resources can improve decisions regarding the allotment and mobilization of medical resources and to better guide future investment in the health sector. AIM The aim of this work was to design and implement a decision support system to improve medical resources allocation of Bejaia region. METHODS To achieve the retrospective cohort study, we integrated e...

Programming non-embarrassingly parallel scientific computing applications such as those involving the numerical resolution of system of PDEs using mesh based methods for grid computing environments is a complex and important issue. This work contributes to this goal by proposing some MPI extensions to let programmers deal with the hierarchical nature of the grid infrastructure thanks to a tree ...
