The main objective of this paper is to introduce a new intelligent optimization technique that uses a predictioncorrectionstrategy supported by a recurrent neural network for finding a near optimal solution of a givenobjective function. Recently there have been attempts for using artificial neural networks (ANNs) in optimizationproblems and some types of ANNs such as Hopfield network and Boltzm...

in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...

In this work, an artificial neural network (ANN) model along with a combination of adaptive neuro-fuzzy inference system (ANFIS) and particle swarm optimization (PSO) i.e. (PSO-ANFIS) are proposed for modeling and prediction of the propylene/propane adsorption under various conditions. Using these computational intelligence (CI) approaches, the input parameters such as adsorbent shape (S<su...

We first present a new service network design model for freight consolidation carriers, one that both routes commodities and the resources needed to transport them while explicitly recognizing that there are limits on how many resources are available at each terminal. We next present a solution approach that combines column generation, meta-heuristic, and exact optimization techniques to produc...

The China-EU freight train is a physical link connecting the Eurasian continent in new era and bridge for expanding economic trade cooperation. Since its opening 2011, trains have developed rapidly. 2015, it has been normalized fixed, now entered stage of steady growth. Based on gravity model, this paper calculates coefficients between China rest world 2015 2019, then establishes analysis const...

In this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (SWCNT) is reported. Methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. Some physical properties of the methanol-water mixture such as r...

this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...
