The application of the Industrial Ethernet brings up issues of both the reliability and behaviour of the networks under a demanded load, while preserving the permitted time delay in the whole network. We propose an algorithm that designs the network topology, which meets the required fault tolerance and allows reliable communication between the parts of the control system. For this purpose, we ...

Active contour models have been part of extensive research since their introduction in the late eighties, because their concept of coupling the image data with shape control is a powerful method to delineate non-rigid curves. Various applications and enhancements have been examined using this technique, for example the development of multiple and coupled active contour models. Latest research d...

a neural network is developed for the determination of leaky confined aquifer parameters. leakage into the aquifer takes place from the storage in the confining aquitard. the network is trained for the well function of leaky confined aquifers by the back propagation technique and adopting the levenberg–marquardt optimization algorithm. by applying the principal component analysis (pca) on the a...

We have understood more precise about the Internet characteristics by the rapid development of the measure, which help us to design new network. In this paper, we analysis the characteristics, including the power-law, hiberarchy and community structure mainly. We propose a new model based on hierarchical framework in accordance with the actual process of internet construct. The model can genera...

This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

The topology control is one of the research focuses in wireless sensor networks. Different network topologies will have different effects on the properties of the network, such as the reliability, energy consumption and latency. In order to study the relationship between the topology and the network performance, in this paper we have designed three kinds of topology models which are regular hex...

We present a method for inferring the topology of a sensor network given non-discriminating observations of activity in the monitored region. This is accomplished based on no prior knowledge of the relative locations of the sensors and weak assumptions regarding environmental conditions. Our approach employs a two-level reasoning system made up of a stochastic Expectation Maximization algorithm...
