-Among all the speed control techniques for induction motor drives, Direct Torque Control (DTC) method is simple and efficient because DTC is independent of machine rotor parameters and free from d-q transformation. Modern DTC based drives are equipped with estimators, observers, and machine intelligence systems to improve the dynamics and efficiency of the drive. This paper is aimed to focus o...

This paper introduces analysis, control, and comparison of two benchmarking optimization approaches called Genetic Algorithm (GA) Particle Swarm Optimization (PSO) for Direct Torque Control (DTC) a three-phase Induction Motor (IM). study aims to determine the most efficient robust different metaheuristic techniques including PID-PSO PID-GA DTC IM. The purpose proposed control technique that has...

Hyperthyroidism seems to increase metabolic and cardiovascular risk, while the effects of sub-clinical hyperthyroidism are controversial. We evaluated metabolic and cardiovascular parameters in differentiated thyroid carcinoma (DTC) patients with suppressed thyrotropin (TSH) due to levo-thyroxine (L-T4) therapy. We studied DTC patients and, as a control group, patients with a history of surgery...

It is often accepted as common knowledge that military personnel benefit from decompression time between a war zone and the home station. To capitalize on the potential benefits of a decompression period paired with support services, the U.S. Air Force established the Deployment Transition Center (DTC) at Ramstein Air Base in Germany in July 2010. The DTC provides airmen returning from combat m...

background: the aim of this study was to understand any association between differentiated thyroid carcinoma (dtc) and ile3434thr xrcc7 gene polymorphism (genbank accession number: rs7830743). dtc is the most prevalent thyroid neoplasm, which includes papillary and follicular cell carcinoma. xrcc7 gene encodes a protein that functions in non-homologous end joining dna repair pathway. non-synony...

background: x-ray repair cross-complementing group 1 (xrcc1) gene is a dna repair gene and its non-synonymous single nucleotide polymorphisms (snp) may influence dna repair capacity which has been considered as a modifying risk factor for cancer development. methods: a case-control study was conducted to investigate impact of three frequently studied polymorphisms (arg194trp, arg280his and arg3...

Energy storage is a vital aspect for the successful implementation of renewable energy resources on global scale. Herein, we investigated redox cycle nickel dithiocarbamates potential use as catholytes in non-aqueous flow batteries. The unique (Ni(dtc)2) offers ability to better understand these reactions by displaying 2e- chemistry upon oxidation from Ni(II) → Ni(IV) but 1e- reduction Ni(III) ...

This paper presents a Direct Torque Control (DTC) strategy for the five-phase induction motor driven by a three-level five-phase inverter in order to improve the performance of the five-phase induction motor. In the proposed DTC technique, only 22 voltage vectors out of 243 available voltage vectors in a three-level five-phase inverter are selected and are divided in 10 sectors each with a widt...
