Mobility management is a leading factor in personal communications services networks. Thus, it is important to verify that the mobile unit receives all services whenever moving from one place to another. This paper deals with the study and analysis of the optimal transmission power at a specific zone through a GSM cellular network. The definition of coverage area is constructed by a proper anal...
BACKGROUND Mali is endemic for all five targeted major neglected tropical diseases (NTDs). As one of the five 'fast-track' countries supported with the United States Agency for International Development (USAID) funds, Mali started to integrate the activities of existing disease-specific national control programs on these diseases in 2007. The ultimate objectives are to eliminate lymphatic filar...
Advances in sensor and communication technologies have made it possible to manufacture small sensors with sensing, processing, and wireless communication capabilities in a costeffective fashion. A sensor network can be formed by deploying specialized sensors in the region of interest to perform certain sensing and networking tasks. Application scenarios of wireless sensor networks include battl...
In this work we attempted to determine the relative importance of the geographical and WordNet-extracted terms with respect to the remainder of the query. In our system, geographical terms are expanded with WordNet holonyms and synonyms and indexed separately. We checked the relative importance of the terms by multiplying their weight by 0.75, 0.5 and 0.25. The comparison to the baseline system...
We present bio-inspired computation techniques, such as genetic algorithms, for real-time self-deployment of mobile agents to carry out tasks similar to military applications. Under the harsh and bandwidth limited conditions imposed by military applications, self-spreading of autonomous mobile nodes becomes much more challenging. In our approach, each mobile agent exchanges its genetic informat...
Geographic Proximity, Trade and International Conflict/Cooperation This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically close, but has a greater effect on coo...
