a study was conducted to determine habitat suitability of goitred gazelle (gazella subgutturosa) in kalmand-bahadoran protected area during four seasons of year 2003-2004.the geographic position of dispersal points of gazelle herds was recorded with global position system. the data were transmitted into attributed tables in arc view software and their layers were created. the maps of slope, alt...

Location services are used in mobile ad hoc and hybrid networks either to locate the geographic position of a given node in the network or for locating a data item (content). One of the main usages of position location services is in location based routing algorithms. In particular, geographic routing protocols can route messages more efficiently to their destinations based on the destination n...

ASSTRACT.--Intraspecific variation in plumage was used to test the null hypotheses that geographic variation in 280 species of elevationally restricted Andean forest birds is independent of elevation and is not a function of patchy geographic distribution. Both null hypotheses were rejected. At most taxonomic levels, geographic variation in plumage was correlated positively with both the mean o...

A focus of the scientific community is to design network oriented position-based routing protocols and this has resulted in a very high number of algorithms, different in approach and performance and each suited only to particular applications. However, though numerous, very few position-based algorithms have actually been adopted for commercial purposes. This article is a survey of almost 50 p...

Geographic routing has received an increasing attention in the context of Wireless Sensor Networks since it frees the network from the energy-demanding task of building and maintaining a structure. It requires however each node to know its position, which may be a prohibitive assumption for many applications. To this end, some prior work has focused on inferring a node’s location from a set of ...

Current approaches to the formal representation of geographical reality are characterized by their static character. GIS representations are representations of the world at a given time, reflecting the fact that geographic information systems have their roots in printed maps. Yet, geographical reality, like all other domains of reality, is essentially dynamic. We here outline a theory that is d...

In this paper we present a routing scheme for on-demand construction of multiple non-interfering paths in wireless sensor networks. One usage of this multipath scheme is to provide a source the ability to increase the likelihood that its data reaches the sink by sending a copy of a packet on more than one path. The routing scheme is based on the assumption that the sensor nodes are aware of the...

conclusions the mental foramina were most commonly located between the first and second premolars and below the apex. a continuous appearance was the most common appearance for the mental foramen, which was similar in males and females. background the position of the mental foramen is critical for surgery and local anesthesia. objectives this study was conducted to assess the position of the me...
