The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...

Bushehr Bay is situated along the northern Iranian coasts of the Persian Gulf, between 28°52΄ and 29°5΄ north latitude and 50°42΄ and 50°52΄east longitude. In this study COHERENS, which is a threedimensional hydrodynamic model, was employed to simulate surface and under surface currents in the Bushehr Bay. The atmospheric forces and four main tidal constituents M2, S2, K1, O1 and also boundary ...

introduction: determination of waves and the pattern of coastal currents is the first step in finding the effective physical factors on marine environments and coastal regions. moreover, wave induced currents play important roles in the determination of geometry and shape of coasts. in this research, patterns of longshore currents are simulated for situations before and after construction of je...

background: ketamine is a commonly used intravenous anesthetic which produces dissociation anesthesia, analgesia, and amnesia. the mechanism of ketamine-induced synaptic inhibition in high-level cortical areas is still unknown. we aimed to elucidate the effects of different concentrations of ketamine on the glutamatergic synaptic transmission of the neurons in the primary somatosensory cortex b...

Recently, smart grids have been considered as one of the vital elements in upgrading current power systems to a system with more reliability and efficiency. Distributed generation is necessary for most of these new networks. Indeed, in all cases that DGs are used in distribution systems, protection coordination failures may occur in multiple configurations of smart grids using DGs. In different...

All living cells have a membrane which separates inside the cell from it's outside. There is a potential difference between inside and outside of the cell. This potential difference will change during an action potential. It is quite common to peruse action potentials of skeletal muscle fibers with the Hodgkin-Huxley model. Since Hodgkin and Huxley summarized some controlling currents like inwa...

In this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (PMHS) motor has been presented. Vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...

The purpose of this study is to identify the role of sport as a soft power for Iranto facilitate its diplomatic relations after the nuclear deal. The research methodused in this study is mixed (qualitative and quantitative): in the qualitative part ofthe analysis, the study sample was selected via Snowball sampling based onpartricipants’ expertise in the sport diplomacy ...
