In this work we show a performance improvement of our system by taking into account the weights of the mixture of Gaussians of the Hidden Markov Model. Furthermore and independently tunning of each of the phoneme Support Vector Machine (SVM) parameters is performed. In our system the user utters a pass phrase and the phoneme waveform segments are found using the Automatic Speech Recognition Tec...

The low harmonic distortion and reduced switching losses are the advantages of using multilevel inverter. For this purpose, three-level inverter is used in paper as a three-phase four-leg shunt active power filter (SAPF). SAPF to eliminate current compensate reactive current, balance load currents under an unbalanced non-linear load. A fuzzy logic controller self-tuning filters (STF) control (A...

The plasmonic resonance frequency of metal nanoparticles (NPs) strongly depend on the geometry, size, and separation between NPs. Here, a structure is designed based film-coupled nanoparticle phenomenon analytically investigated by finite element method via COMSOL Multiphysics software tool. optical behavior studied compared for two noble metals (gold silver as case study). Simulation results c...

Numerous algorithms have been proposed for the well-known multi-constrained shortest path problem, but very few have good practical performance when there are two or more constraints. In this paper we propose a new Lagrangian relaxation algorithm that finds multiple shortest paths subject to multiple constraints. It follows the same procedure as some related work by first identifying the lower ...

The present work proposes a control parameter adjustment technique using Kalman filter applied to an adaptive control strategy. The control algorithm is based on neural networks with on-line learning to compute the next action of the manipulated process variables. The penalization parameters of the control actions are on-line optimised by the Kalman filter. The control strategy was tested on an...

Finding a efficient or correct choice of preprocessing level can reduce the search time of a constraint solver to find a solution to a constraint problem. Currently the parameters in constraint solver are often picked by hand by experts in the field. Sexual Genetic Algorithm are a algorithm which applies two different selection strategies during the mating. In this paper the efficiency of Sexua...

Abstract In this paper, a surrogate merit function (SMF) is proposed to be evaluated instead of the traditional functions (i.e., penalized weight structure). The standard format conventional needs several expensive trial-and-error tuning processes enhance optimization convergence quality, retuning for different structural model configurations, and final manual local search in case converges inf...

Asphaltene are large molecular crude constituents and their existence is related to numerous problems. However, nanofluids have proven be a very stable effective way of dealing with asphaltene agglomerations. This research addresses the effectiveness as compared traditional available (FLOW-X) commercial inhibitors. The synthesis characterization two green NPs preparation were performed successf...
