We propose a hybrid magnonic-oscillator system based on the combination of spin transfer auto-oscillator and magnonic waveguide to open new perspectives for spin-wave circuits. The is composed oscillator vortex state which dipolarly coupled nanoscale with longitudinal magnetization. In its auto-oscillating regime, emits coherent waves tunable controllable frequencies, directions, amplitudes int...

Due to the air pollution crisis and increase in greenhouse gases, emission standards are getting tougher gradually. In the other hand reducing the consumption of nonrenewable resources is one of the main goals of the automotive industries in the world. Using electric propulsion along with internal combustion engine is one of the answers. Different designs of Hybrid Electric Vehicles (HEV) have ...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

In this paper, we introduce hybrid of block-pulse functions and Bernstein polynomials and derive operational matrices of integration, dual, differentiation, product and delay of these hybrid functions by a general procedure that can be used for other polynomials or orthogonal functions. Then, we utilize them to solve delay differential equations and time-delay system. The method is based upon e...

Energy is one of the most important requirements in development of societies. In the last decade, widespread attention has been paid to renewable energies. Despite the obvious advantages of renewable energy resources, their dependence on climate change is one of the most fundamental problems facing to the development of them. Optimal design of hybrid renewable energy systems is a major issue in...

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...
