Currency crises appear to spread regionally. In this paper we use Bayesian methodology on data from four waves of currency crises in the late twentieth century to examine the mechanism by which currency crises spread from one country to another. In particular, we examine whether trade linkages, “other” unquantifiable linkages proxied for by relative geographical distance, or macroeconomic and f...

Geographical Bioinformatics Systems (GBS) represent the marriage between two distinct and well established fields, GIS & Bioinformatics. Bioinformatics refer to the use of computers to handle biological information—that is, the use computers to store, compare, retrieve, analyze and predict the composition or structure of biomolecules. On the other hand, the term Geographic Information Systems (...

Data modeling is defined as the process of discretizing spatial variation, but is often confused with issues of data structure, and driven by available software rather than by a concern for accurate representation. We review the alternative data models commonly available in spatial databases, and assess them from the perspective of accurate representation of geographical reality. Extensions are...

introduction: oral diseases are the most prevalent diseases probable at any age. they are chronic in nature and expensive to care.  accurate, comprehensive, well-structured, well-managed data is required to control and prevent oral diseases, clinical audit, quality of patient care, and administrative, financial, research and legal goals fulfillment we need. in dentistry, data collection would p...

Assigning geographical coordinates to shared content has become a popular activity on the Web, but nevertheless there are still huge amounts of media data without any geographical tags. Our approach enables these media data to be geotagged with the help of recently tagged media and knowledge-based collaborative systems. It includes three different methods–querying collaborative systems, documen...

Quality spatial load forecasting is a major prerequisite for energy distribution systems planning. The load evolution outline depends on the urban expansion and its land usage. This paper presents a methodology for knowledge extraction of the data provided by a GIS (Geographical Information Systems) platform. The main goal consists of developing studies that lead to the understanding of the inf...

Recently, the demands on information services have been increasing significantly. This is mainly due to the popularization of computer and mobile telecommunication devices and the rapid improvements on wireless communication technology. Specially, information services and their corresponding management for mobile devices, such as Location Based Service (LBS) and Telematics, become more and more...
