Two stochastic methods for locating global minimum and optimal design parameters of a rectifier power transformer, by Genetic Algorithm (GA) and Simulated Annealing (SA) are presented. A closed form expression for actual phase current waveform of the rectifier transformer is derived and a comparison is made with the approximate waveform normally considered for fixing the transformer rating. The...

In this work a model-based methodology to solve an integrated process design and control (IPDC) problem for a bioethanol production process is presented. The IPDC problem is formulated and solved such that the economic performance is optimized in terms of a cost effective design and controllable process. The concepts of attainable region (AR) and driving force (DF) are used within this methodol...

One of the main challenges for transportation engineers is the consideration of pedestrian safety as the most vulnerable aspect of the transport system. In many countries around the world, a large number of accidents recorded by the police are composed of accidents involving pedestrians and vehicles, for example when pedestrians may be struck by passing vehicles when crossing the street. Carefu...

‎Let $f$ be a proper $k$-coloring of a connected graph $G$ and‎ ‎$Pi=(V_1,V_2,ldots,V_k)$ be an ordered partition of $V(G)$ into‎ ‎the resulting color classes‎. ‎For a vertex $v$ of $G$‎, ‎the color‎ ‎code of $v$ with respect to $Pi$ is defined to be the ordered‎ ‎$k$-tuple $c_{{}_Pi}(v)=(d(v,V_1),d(v,V_2),ldots,d(v,V_k))$‎, ‎where $d(v,V_i)=min{d(v,x):~xin V_i}‎, ‎1leq ileq k$‎. ‎If‎ ‎distinct...

Aim: In an attempt to broaden the concept that neutrophil...

In view of this situation, our research project aims at accurately locating UAVs in detection mode, effectively damaging defensive means, and constantly suppressing key technologies. The optimal anti-UAV scheme is formulated. Combining with the above program, together control relevant monitoring ZTE decision-making center, prevention command system set up camp. According to characteristics diff...

Abstract The construction of injection wells is one the direct methods artificial recharge and determining their optimal location important issues that are discussed in topics projects related to rehabilitation aquifers. In this research, a simulation–optimization model was proposed determine using Isogeometric analysis (IGA) numerical Grey wolf optimization algorithm (GWO). regard, first, grou...
