Especially scenarios like public safety or battle field require reliable Multicast (voice) communication. There are different ways to choose and maintain the groups of receivers. One alternative for certain use cases, especially for areas of danger, is Geocast. Using Geocast, a receiver is defined by its geographic position. Especially for mobile ad hoc networks (MANETs) there are several Geoca...

INTRODUCTlON ,. . The foundation of most evolutionary theory rests upon inferences drawn from geographic variation or upon the verification of predictions made about it. The study of geographic variation occupies a central position in evolutionary biology. .. because geographic variation is ordinarily the smallest amount of evolution that can be detected in nature and because evolutionary theor...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

having a comprehensive and correct understanding of grazing behaviour of livestock helps to maximize livestock products. moreover, a good understanding of livestock behavior allows us to predict the effects of livestock on rangeland and finally we can do livestock grazing management the best possible. recognition of grazing behavior of animals can provide solutions enables the optimal use of ra...

At the end of the Middle Miocene the Caucasus represented a land forepart, the geographic position of which induced the development of peculiar flora and fauna in Eastern Georgia. On the territory of Eastern Georgia several reference fossil vertebrate sites are discovered, among them its worth mentioning Udabno (Maeotian), Dzedzvtakhevi (Maeotian), Iaghludja (Sarmatian-Maeotian), Kvabebi (Akcha...
