Energy expenditure has become a significant fraction of data center operating costs. Recently, “geographical load balancing” has been suggested as an approach for taking advantage of the geographical diversity of Internet-scale distributed systems in order to reduce energy expenditures by exploiting the electricity price differences across regions. However, the fact that such designs reduce ene...

Currently there are thousand container events happening daily on more than 20 000 locations in the World. Some of these locations are big international ports and others are just little cities with not precise coordinates in the free available Data Bases (DB). Verification and validation these locations are at the same time a very important task and a challenging one. This paper describes the de...

The rapid emerging of mobile Internet provides new opportunities for information services. One of the service types is tied to mobile location technology that allows defining the geographical location of a mobile user. It enables the development of new class geographical information services. Location-based applications require careful development of the general architecture as well as a data f...

The value of geographical information systems and remote sensing as tools for land and resource management is now widely recognised and their application well documented. Better integration of the technologies offers the potential, however, for developing more powerful and useful tools for land and resource management. This paper focuses on the integration of image data with geographical inform...

Current geographical information applications increasingly require managing spatial data through the Web. Users of geographical information application need not only to display the spatial data but also to interactively modify them. As a result, the security risks that face geographical information applications are also increasing. In this paper, a secured framework is proposed. The proposed fr...

Many real-world spatially related problems, including river-basin planning and management, give rise to geographical information system based decision making, since the performance of spatial policy alternatives were traditionally and are still often represented by thematic maps. Advanced technologies and approaches, such as geographical information systems (GIS), offer a unique opportunity to ...
