this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...

introduction: 17β-estradiol modulates nociception by binding to estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. beside its autonomic functions, paragigantocellularis lateralis (lpgi) nucleus is also involved in pain modulation. the aim of the current study was to investigate the role of the intracellular estrogenic ...

in this paper first we try to analysis the behavior ofthe soas in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. after that by employing thismodel as inline amplifier for a dwdm optical system, we havesimulated the transmission of 10 channels with bit rate 10 gb/sup to distance 3970 km with rz-dpsk modulation ...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

Introduction: It is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. Orexin plays an important role in modulation of pain and stress. Considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.We evaluated the involvement ...

Introduction: 17β-estradiol modulates nociception by binding to estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and GABAA receptors. Beside its autonomic functions, paragigantocellularis lateralis (LPGi) nucleus is also involved in pain modulation. The aim of the current study was to investigate the role of the intracellular estrogen...
