Computational neurobiology is an emerging eld which employs models to simulate the behavior of real neural systems We present an environment that can be used to guide simulations using existing neural models This environment is based on Perl a powerful and standard script language It also contains a standard library of routines for common simulation tasks Included in the environment is an optim...

Recently, various sophisticated strategies adapted to current network conditions have been proposed for channel allocation based on intelligent techniques such as evolutionary and genetic algorithms. These approaches constitute heuristic solutions to resource management problems in modern cellular systems. On the other hand, the ant colony optimization approach has been proposed for solving sev...

The paper deals with the distributed solution of simulation based nonlinear constrained optimization problems in engineering on a network of workstations. This type of non-linear optimization and control problems in engineering can be generally characterized as non{convex and non-smooth. Additionally, the involved simulation introduces certain numerical "noise\ to the solution process. These ch...

The researchers made significant progress in all of the proposed research areas. The first major task in the proposal involved simulation-based and sampling methods for global optimization. In support of this task, we have discovered two new innovative approaches to simulation-based global optimization; the first involves connections between stochastic approximation and our model reference appr...

compared to conventional chlorination methods which apply chlorine at water treatment plant, booster chlorination has almost solved the problems of high dosages of chlorine residuals near water sources and lack of chlorine residuals in the remote points of a water distribution system (wds). however, control of trihalomethane (thm) formation as a potentially carcinogenic disinfection by-product ...

in this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. for these types of systems avoiding failure during the actual operation of the system is extremely important. in this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

we use a multi-resolution analysis based on a wavelet transform to upscale a 3d fractured reservoir. this paper describes a 3d, single-phase, and black-oil geological model (gm) that is used to simulate naturally-fractured reservoirs. the absolute permeability and porosity of gm is upscaled by all the possible combinations of haar, bior1.3, and db4 wavelets in three levels of coarsening. the ap...

An approach, based on queuing modeling and simulation, to resource allocation for a distributed production system is examined in the paper. The problem is formulated as an objective function minimization for a queuing network. The optimization is based on the combination of analytical modeling and simulation. The analytical model is used for primary evaluation and branching for the optimization...

discrete element method (dem) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by dem simulation. in this article, a new approach was used to assess the main paramet...
