In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...

The aggregate capacity of wireless mesh networks can be improved significantly by equipping each node with multiple interfaces and by using multiple channel in order to reduce the effect of interfaces .Wireless Mesh Networks (WMNs) have the potential for improving network capacity by employing multiple radios and multiple channels (MRMC).Several efforts have been made to increase capacity. One ...

This paper addresses questions about how the distribution of the generalized coherence (GC) estimate formed with data from several noisy channels is aaected by prior knowledge about the presence of a signal on one or more of the channels. In particular, the distribution of the estimate is shown to be invariant to the statistics of one of the channels under established signal-absent hypotheses o...

the main objective of this article is to present the result of a research on industrial distribution network in iran which for the first time is being carried out for the purpose of recognizing the industrial goods distribution network, estimation of the volume of transaction in each case, and to study the impact of certain elements. the factors and variables which their impact on the volume of...

Redistribution of sodium channels along demyelinated pathways in multiple sclerosis (MS) could be an important event in restoring conduction prior to other reparative mechanisms such as remyelination. Sodium channels in human multiple sclerosis lesions were identified by quantitative light microscopic autoradiography using tritiated saxitoxin (STX), a highly specific sodium channel ligand. Demy...

The Weibull distribution is a flexible statistical model for describing multipath fading channels in both indoor and outdoor radio propagation environments. A new closed-form expression is derived for the moment generating function of the Weibull distribution, valid when its fading parameter assumes integer values. The performance of digital linear modulations operating on Weibull channels is s...
