The Direct Torque Control (DTC) is one of the most effective control and modern methods for high performance AC drives in a wide variety of industrial application and conventional DTC technique uses two constant reference values stator flux and torque ripple. In this paper, two approach intelligent techniques such as fuzzy logic (FL) and Artificial Neural Networks (ANN) used to improving the pe...

Coexistence of differentiated thyroid cancer (DTC) and thyroid autoimmune diseases could represent a mere coincidence due to the frequent occurrence of autoimmunity, but there may also be a pathological and causative link between the two conditions. The coincidence of DTC with Hashimoto's disease has been variably reported at between 0.5 and 22.5% and of DTC with Graves' disease between 0 and 9...

Objectives. Invasion of differentiated thyroid cancer (DTC) into surrounding structures can lead to morbid procedures such as laryngectomy and tracheal resection. In these patients, there is a potential role for neoadjuvant therapy. Methods. We identified three studies involving the treatment of DTC with neoadjuvant chemotherapy: two from Slovenia and one from Japan. Results. These studies demo...

In C. elegans, germline mitosis depends on induction by the somatic distal tip cell (DTC) and on activity of the glp-1 gene. Using antibodies to GLP-1 protein, we have examined GLP-1 on western blots and by immunocytochemistry. GLP-1 is tightly associated with membranes of mitotic germline cells, supporting its identification as an integral membrane protein. Furthermore, GLP-1 is localized with...

The Caenorhabditis elegans distal tip cells (DTCs) are an in vivo model for the study of developmentally regulated cell migration. In this study, we characterize a novel role for CCDC-55, a conserved coiled-coil domain containing protein, in DTC migration and larval development in C. elegans. Although animals homozygous for a probable null allele, ccdc-55(ok2851), display an early larval arrest...

Floquet time crystal, which breaks discrete time-translation symmetry, is an intriguing phenomenon in non-equilibrium systems. It crucial to understand the rigidity and robustness of crystal (DTC) phases a many-body system, finding precisely solvable model can pave way for understanding DTC phase. Here, we propose study spin chain by mapping it superconductor through Jordan-Wigner transformatio...

This paper compares three direct control strategies por induction machines, analizing it’s performance for electric vehicle tration. The stretegies analysed are DTC, DTC with PI controllers and PTC, driving an motor a mechanical dinamic model of as the load. Simulation shows that all suitable to use in EV traction, but modulation results better current THD torque/flux ripple. Between classic pr...

This paper describes a combination of direct torque control (DTC) and space vector modulation (SVM) for an adjustable speed sensor less induction motor (IM) drive. The motor drive is supplied by a two-level SVPWM inverter. Using the IM model in the stator – axes reference frame with stator current and flux vectors components as state variables. In this paper, a conventional PI controller is des...

The effects of d-tubocurarine (dTC) on nicotinic synapses on sympathetic B and C neurons in the bullfrog were compared by recording trains of postganglionic compound action potentials (CAPs) at 0.5-20 Hz. Block by dTC was strongly use dependent in that the IC50 shifted almost 10-fold with increasing stimulus frequency. Maximum sensitivity to dTC occurred at 5 Hz in the B system and at 20 Hz in ...

PURPOSE/OBJECTIVES To obtain information about the knowledge and attitudes of oncology nurse practitioners (ONPs) concerning the effect of direct-to-consumer (DTC) advertising of prescription medications on prescribing patterns. DESIGN Exploratory survey. SETTING Oncology Nursing Society Nurse Practitioner Special Interest Group members in the United States. SAMPLE 221 of 376 ONPs complet...
