While creating an industrial system which has an electric motor, the designers should to be think over not only control method but also motor type to create successful and efficiency system. If created system is an electric vehicle, designers have two powerful candidates as traction motor: Brushless AC (BLAC) or Brushless DC (BLDC) motors. In this study, a comparative performance investigation ...

Background. The aims of this study were to assess patients' preferences to wait or start systemic treatment and understand how patients would make tradeoffs between certain severe adverse events (AEs) and additional months of progression-free survival (PFS). Materials and Methods. Adults in France, Germany, and Spain with a diagnosis of DTC and who have had at least one RAI treatment completed ...

Purpose. To understand the role of polymorphisms in the LEP (rs7799039 and rs2167270) and LEPR (rs1137101 and rs1137100) genes in DTC susceptibility and their effect on leptin levels. Methods. We studied 153 patients with DTC and 234 controls through TaqMan SNP Genotyping and ELISA, comparing these data to the clinicopathological data of patients with DTC. Results. Patients with AA genotype of ...

The aim of this paper is to review the origin and developments of direct torque control (DTC), an advanced control technique of induction motor drives yielding superior performance. The direct torque control is one of the excellent control strategies available for torque control of induction machine. It is considered as an alternative to field oriented control (FOC) technique. The DTC is charac...

Direct torque control (DTC) is an advanced control technique, in which the torque produced by the motor is directly controlled by controlling the inverter switching states. Each switching state represents a voltage vector. DTC have the following features, it does not requires current controllers, elimination of rotor position sensors, fast torque response, lesser parameter dependence, and it do...

Prophylactic central neck dissection (pCND) in differentiated thyroid carcinoma (DTC) is one of the most controversial surgical subjects in recent times. To date, there is little evidence to support the practice of pCND in patients with DTC undergoing total thyroidectomy. Although the recently revised American Thyroid Association (ATA) guideline has clarified many inconsistencies regarding pCND...

The National Centers for Environmental Prediction (NCEP) and the Developmental Testbed Center (DTC) have both developed software packages with the capability to verify model forecasts using several verification methods. NCEP employs both the NCEP Verification System (NVS) and the Quantitative Precipitation Forecast (QPF) Verification System (QVS), while the DTC uses the Model Evaluation Tools (...

This paper presents a speed sensorless direct torque control scheme using space vector modulation (DTC-SVM) for permanent magnet synchronous motor (PMSM) drive based a Model Reference Adaptive System (MRAS) algorithm and stator resistance estimator. The MRAS is utilized to estimate speed and stator resistance and compensate the effects of parameter variation on stator resistance, which makes fl...

In this article, the new closed-loop current harmonics compensation strategy is introduced in switching-table-based direct torque control (ST-DTC) of dual three-phase permanent magnet synchronous machines. The harmonic distortion major problem ST-DTC multiphase machines and typically caused by lack auxiliary x-y subspace under vector space decomposition model. synthetic vectors to obtain averag...
