Clustering is an effective approach for managing nodes in Wireless Sensor Network (WSN). A new method of clustering mechanism with using Binary Gravitational Search Algorithm (BGSA) in WSN, is proposed in this paper to improve the energy consumption of the sensor nodes. Reducing the energy consumption of sensors in WSNs is the objective of this paper that is through selecting the sub optimum se...

We present first calculations of new long-distance contributions to Bs → γγ decay due to intermediate Ds and D ∗ s meson states. The relevant γ vertices are estimated using charge couplings and transition moment couplings. Within our uncertainties, we find that these long-distance contributions could be comparable to the known short-distance contributions. Since they have different Cabibbo-Koba...

In this paper, we analyse the joint impact of pathloss, shadowing and fast fading on wireless networks. Taking into account the pathloss and the shadowing, we first express the SINR distribution of a mobile located at a given distance from its serving base-station (BS). The moments of this distribution are easily computed, using the Fenton-Wilkinson method, and a fluid model that considers the ...

The purpose of this study is to evaluate the present status of Mashhad’s Bicycle Sharing (BS) Program's stations, and to locate future stations, taking into account the 7 criteria of “proximity to subway stations”, “proximity to other stations”, “distance from important intersections”, “distance from population centers”, “proximity to educational, recreational and commercialcenters”, “slope lev...

Korea has made a plan to transfer from analog television to Digital Television (DTV). Therefore, TV White Spaces (TVWS)are the unused TV broadcast channels which can be available for wireless communication systems. This paper assumes that DTV operates on Channel 34 and Long Term Evolution (LTE) is assumed that it uses Frequency Division Duplexing (FDD), and then upper 4 MHz of Channel 32 and ch...

The formation of base-pairing between the branch-site (BS) sequence and the U2 snRNP is an important step in mRNA splicing. We developed a new algorithm to identify both the BS sequence and the polypyrimidine tract (PPT) and validated its predictions experimentally. To assess BS conservation between human and mouse, we assembled and analyzed 46 812 and 242 constitutively and alternatively splic...

Base Station (BS) location and physical topology of a network play an important role in a Wireless Sensor Networks (WSN) because the BS position governs the lifetime of networks. Optimizing the topology reduces the issues that arise due to the location of the destination node. During network formation, some nodes have tends to have that have longer distance to BS. In this case, data has to trav...
