Wireless Sensor Networks are the new generation of networks that typically are formed great numbers of nodes and the communications of these nodes are done as Wireless. The main goal of these networks is collecting data from neighboring environment of network sensors. Since the sensor nodes are battery operated and there is no possibility of charging or replacing the batteries, the lifetime of ...

Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). The discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as “Marrara syndrome”. In current study, the prevalence of infection with L. serrata nymphs in mesenteric lymph nodes (...

a wireless sensor network (wsn) is a wireless decentralized structure network consists of many nodes. nodes can be fixed or mobile. wsn applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in wsn. wireless localization used to determine the position of nodes. the precise localization in wsns is a co...

In this paper, a supply chain network design problem is explained which contains environmental concerns in arcs and nodes of network. It is assumed that there are some routes such as road, rail and etc. in each pair of nodes. In this model decision variables are choosing facilities to open, environmental investment level in each facility and flow of products between nodes in each route. A multi...

a wireless sensor network consists of many inexpensive sensor nodes that can be used toconfidently extract data from the environment .nodes are organized into clusters and in each cluster all non-cluster nodes transmit their data only to the cluster-head .the cluster-head transmits all received data to the base station .because of energy limitation in sensor nodes and energy reduction in each d...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

A communication coprocessor that provides highbandwidth low-latency inter-node communication is a key component of multicomputer systems composed of hundreds of computing nodes interconnected by point-to-point links. For high reliability, interdependency between nodes is minimized by using a separate clock at each node. Thus, the coprocessor must handle asynchronous inputs with a very low proba...

the efficacy of bacterial cultures and is900-specific polymerase chain reaction (pcr) was compared for the detection of mycobacterium avium subsp. paratuberculosis (map) from the mesenteric lymph nodes of goats. samples were collected from 75 goats slaughtered in ilam, in southwest of iran. tissue homogenates were inoculated onto four media. the genomic dna was extracted directly from mesenteri...
