Various aspects related to controlling induction motors are investigated. Different control strategies are explored. The direct torque control (DTC) strategy is studied in details and its relation to space vector modulation (SVM) is emphasized. An SVM-based DTC strategy is suggested and a controller design based on this strategy is presented. A Simulink model representing the controller is deve...

INTRODUCTION Differentiated thyroid carcinoma (DTC) in children presents different biological behavior in comparison to adults. Authors presents preliminary results of multicenter analysis concerning incidence, diagnostics and treatment of DTC in children. MATERIAL AND METHODS The study is a retrospective analysis of 107 pediatric patients from 14 academic centers based on the data from 2000 ...

The model of three-phase permanent magnet synchronous motor (PMSM) with loss of one phase or loss of one transistor is built and its fault tolerant direct torque control (DTC) is investigated. Extra-leg extraswitch inverter is put to use in the post-fault operation. Two different flux estimators are employed in order to calculate stator flux linkage & their corresponding torque and switching ta...

OBJECTIVES To analyze the clinical and histopathological features of patients with thyroid cancer in the southwest Madrid area and to identify poor prognostic factors in the subgroup with differentiated thyroid carcinoma (DTC) of the follicular epitelium. PATIENTS AND METHODS A retrospective cohort study of patients diagnosed with thyroid cancer at our hospital from 1998 to 2009. Significant ...

-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...

Although cancer outcome results from the interplay between genetics and environment, researchers are making a great effort for applying molecular biology in the prognostication of differentiated thyroid cancer (DTC). Nevertheless, role of molecular characterisation in the prognostic setting of DTC is still nebulous. Among the most common and well-characterised genetic alterations related to DTC...

BACKGROUND Linkage analyses and association studies suggested that inherited genetic variations play a role in the development of differentiated thyroid carcinoma (DTC). METHODS We combined the results from a genome-wide association study (GWAS) performed by our group and from published studies on DTC. With a first approach, we evaluated whether a SNP published as associated with the risk of ...

BACKGROUND It is unclear whether common genetic variants of the RET proto-oncogene contribute to disease susceptibility, clinical severity, and thyroid function in differentiated thyroid cancer (DTC). METHODS A total of 300 DTC patients and 252 healthy controls were enrolled in this study. Seven RET tagging single nucleotide polymorphisms were genotyped using the KASPar platform. RESULTS Su...

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...
