aces in the audience on the 25th of January! "How to win a house job" is not a subject to which there is a short answer, but rather one in which the importance lies ln the summation of a lot of minor points plus a few more major and more definite ?nes, so I shall give a general factual background and then some more detailed advice. The factual background I decided to obtain from a questionnaire...

This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...

Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...

While direct, model-free reinforcement learning often performs better than model-based approaches in practice, only the latter have yet supported theoretical guarantees for finite-sample convergence. A major difficulty in analyzing the direct approach in an online setting is the absence of a definitive exploration strategy. We extend the notion of admissibility to direct reinforcement learning ...

The paper presents a super-twisting sliding mode (STSM) regulator with neural networks (NN) of direct power command (DPC) for controlling the active/reactive power of a doubly-fed induction generator (DFIG) using a two-level space vector pulse width modulation (2L-SVPWM). Traditional DPC strategy with proportional-integral (PI) controllers (DPC-PI) has significantly more active/reactive power r...

Natural gas-diesel dual fuel combustion is a beneficial strategy for achieving high efficient and low emissions operation in compression ignition engines, especially in genset application heavy duty diesel engine at rated power. This study aims to investigate a dual fuel engine performance and emissions using premixed natural gas and early direct injection of diesel fuel. Due to the different r...

The present study aims to provide a model for financing buyer-supplier in Mehrvarzan healthcare Company. The statistical population of the study includes 300 employees of the company. According to Morgan table, 168 people are selected as the statistical sample. Available non-random sampling method has been used. For collecting the required information, the standard buyer-supplier financing ques...

Research findings suggest that the family context and communication patterns have high correlation with adolescent’s mental health indicators such as anxiety. Therefore, the current study aimed to investigate the mediator role of coping strategies in relation between family communication patterns and students social anxiety. 140 students of Shiraz guidance schools were studied they completed th...
