Geographic information (also called geo-information, spatial information or geospatial information) plays an increasingly important role in our society. Location Based Services, applications for urban planning, disaster management systems rely on geo-data and in many cases up-to-date geo-information is crucial, e.g. in disaster response systems. In this paper we focus on a special kind of geo-i...

Geo-neutrinos emitted by heat-producing elements (U, Th and K) represent a unique probe of the Earth interior. The characterization of their fluxes is subject, however, to rather large and highly correlated uncertainties. The geochemical covariance of the U, Th and K abundances in various Earth reservoirs induces positive correlations among the associated geo-neutrino fluxes, and between these ...

The field of Mobile Adhoc Network (MANET) has become very popular because of the deep research done in that area in last few years. MANET has advantage of operating without fixed infrastructure and also it can tolerate many changes in the network topology. The MANET uses different routing protocols for End to End Packet delivery. This paper is subjected to the Reactive routing protocols on the ...

In this paper we introduce non-abelian zeta functions and more generally non-abelian L-functions for number fields, based on geo-arithmetical cohomology, geo-arithmetical truncation and Langlands’ theory of Eisenstein series. More precisely, in Chapter I, we start with a new yet natural geo-arithmetical cohomology and a geo-arithmetical stability in order to define genuine non-abelian zeta func...

A cross-sectional study of the nutritional status of schoolchildren aged 7-10 years from the Kuala Betis Resettlement Scheme in Gua Musang, Kelantan was done. A total of 291 schoolchildren were examined but only 183 (62.9%) fecal samples were returned for geo-helminth infection analysis. The prevalence of stunting was 40.4% and underweight was 28.4%. A total of 127 schoolchildren (69.4%) were p...

New generation remote sensing technologies open today new application areas and demonstrate their effectiveness providing geo-information in support to disaster management. In the same time, new challenges can be identified and among them has a crucial role the validation of geo-information under the new specific constraints dictated by the disaster management application area. In the frame of ...

In this paper we present the research objectives and methodology for a running project of distributed web processing geo-services for spatio-temporal analysis of geo-data, the case of Lloyd’s lists. We introduce the current problems and discuss the solutions in means of theoretical and practical perspectives. Initial results from geo-data modeling using Unified Modeling Language (UML) is presen...

This paper describes our participation at GeoCLEF 2005. We detail the main software components of our Geo-IR system, its adaptation for GeoCLEF and the obtained results. The software architecture includes a geographic knowledge base, a text mining tool for geo-referencing documents, and a georanking component. Results show that geo-ranking is heavily dependent on the information in the knowledg...
