Topological optimization of computer networks is concerned with the selection of a subset of the available links such that the reliability and fault-tolerance aspects are maxhized while meeting a cost constraint. In this case. the problem is stated as opthiring the reliability and fault-tolerance of a network subject to a maximum cost constraint. Existing iterative-based techniques consider the...

One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...

introduction: the internet and other digital sources of information are widely used tools for research. citations allow readers to locate and further explore sources you consulted, show the depth and scope of your research and give credit to authors for their ideas. in this study, documenting electronic sources in journals of medical sciences universities in 1378-81 was investigated.’ methods: ...

Messages transported within a sensor network are subject to losses due to a number of factors. These factors include losses in the wireless channel, MAC layer collisions, node error or failure and losses due to incorrect routing. This paper describes these sources of data loss and discusses the various strategies available to prevent data loss. The effectiveness of each of the strategies to pre...

This paper introduces the development and implementation of a new methodology for optimizing reliability measures of a computer communication network within specifi ed constraints. A genetic algorithm approach with specialized encoding, crossover, and mutation operators to design a layout topology optimizing source-terminal computer communication network reliability is presented. In this work, ...

background: visualattention is known as acritical base for learning.thepurpose of the present study was to design, develop and evaluate the test-retest and internal consistency reliability as well as face, content and convergent validity of thecomputer- based selective visual attention test (sevat) for healthy first-grade school children.   methods :in thefirst phase of this study,the computer-...

we consider a grid network where nodes contain small buffers. a packet that faces a crowded buffer in its route will get extra latency and may be dropped. in this paper, we propose a novel flow control protocol called rfcc for grid networks. rfcc tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

binary decision diagram (bdd) is a data structure proved to be compact in representation and efficient in manipulation of boolean formulas. using binary decision diagram in network reliability analysis has already been investigated by some researchers. in this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using cudd - colorado univer...
