Although a flooding is the most commonly used method for one-toall communications, it often results in huge traffic in mobile ad hoc networks. Several optimization schemes have been proposed to alleviate this problem. However, none of them offers a complete solution and has their own limitations, such as, lack of reliability, high latency or excessive control packet overhead. In this paper, we ...

in this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. the objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. the combination of firefly algorithm, parti...

We propose a joint optimization framework for quality-of-service (QoS) routing with resource allocation in a generalized processor sharing (GPS) network. Our joint optimization framework provides a convenient way of maximizing the reliability or minimizing the jitter delay of paths. Data traffic is sensitive to droppage at buffers while it can tolerate jitter delay. On the other hand multimedia...

the concepts of structural optimization was introduced about sixty years ago. smiths from the university of los angeles (california) for the first time has offered the combination of finite element method and optimization techniques to design optimum structures (1960). at present time, this techniques are generally understood and many softwares for this perpose have been developed. in this pape...

The use of probabilistic optimization in structural design applications is hindered by the huge computational cost associated with evaluating probabilistic characteristics, where the computationally expensive finite element method (FEM) is often used for simulating design performance. In this paper, a Sequential Optimization and Reliability Assessment (SORA) method with analytical derivatives i...

In this paper a brief overview of methods to assess the reliability of mechanical systems and structures is given. A selection of computational procedures, stochastic structural dynamics, stochastic fatigue crack growth, and reliability based optimization are discussed. It is shown that reliability based methods may form the basis for a rational decision making.

In this work we study one of the possible approaches to the optimization of the distribution of reserving files at the nodes of a network based on the reliability criterion. To estimate reliability we use an approach related to the notion of a “reliability order” parameter.

Reducing the size of a logic circuit through lattice identities is an important and well-studied discrete optimization problem. In this paper, we consider a related problem of integrating several circuits into a single hypercircuit using the recently-developed concept of lattice hyperterms. We give a combinatorial algorithm for integrating k-out-of-n symmetrical diagrams which play important ro...
