Geographical routing protocols have been received serious attention due to their advantages as compared to conventional routing protocols. They require information about the physical position of nodes to be available. Commonly, each node determines its own position through the use of Global Positioning System (GPS) or some other type of positioning service. Greedy Perimeter Stateless Routing (G...

background: leiomyomata is the most frequent gynecological neoplasm. one of the major complications of myomectomy is intrauterine adhesion (synechiae). objective: to evaluate and compare the rate and severity of synechiae formation after myomectomy by laparotomy and laparoscopy. materials and methods: in this non-randomized interventional trial, hysteroscopy was performed in all married fertile...

Recent years have witnessed an increasing availability of heterogeneous sensor networks that consist of a large number of resource constrained nodes (sensors) and a small number of powerful resource rich nodes (actors). Such heterogeneous Wireless Sensor Actor Network (WSANs) offer improvement of sensor networks' capacity/coverage, energy conservation and network lifetime. This paper investigat...

Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

1. introduction from cultural and land point of view, national heterogeneity is the characteristic of many countries. so that the vast majority of countries are facing regionalism based on their width and number of population which sometimes they challenge the legitimacy of the government. because of its special geographical situation, iran has been the dwelling of people with various language ...

b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristic...

A geographical information system (GIS) is a framework capable to assemble, keep, process and display specific information, identified by geographical location, which can combines layers of information to give the user a better understanding about that location. Intelligent agents prove to be a useful tool for data mining in geographical distributed knowledge bases. In this paper we present a m...
