Field oriented control (FOC) and direct torque control (DTC), also called vector control, are most famous control methods in high-performance motor applications. If we want to specify the basic handicaps of both methods: the FOC has parameter dependence while the DTC has high torque ripples. This paper proposes a new adaptive bandwidth approach to reduce torque ripples in DTC controlled inducti...

Background: Differentiated thyroid cancer (DTC) is the most prevalent endocrine cancer. Evidence showed a significant association between diet and DTC. Thus, this study aimed to assess the relationship between dietary intakes and DTC. Methods: This case-control study was accomplished among 300 adult patients and 300 matched (age and gender) controls in Mashhad city, Iran. Dietary assessment was...

In the paper a new way of DTC control method analysis to explain flux and current distortion at a low speed of motor operation is discussed. As a result, a new DTC-δ algorithm is proposed. It is important that the DTC-δ algorithm uses the same switching table as the DTC method. The modified DTC algorithms are free from the disadvantages of the conventional DTC method i.e. hexagonal flux and str...

Metastasis is the final stage of cancer progression. Some evidence indicates that tumor cell dissemination occurs early in the natural history of cancer progression. Disseminated tumor cells (DTC) have been described in the bone marrow (BM) of cancer patients as well as in experimental models, where they correlate with later development of metastasis. However, little is known about the tumorige...

Induction motors are most commonly used motor type in industrial applications because of its well-known advantages like robust structure, cheaper prices etc. Today, field oriented control (FOC) and direct torque control (DTC) methods, also called vector control, are most famous control methods in high-performance applications. The main structural and behavioural differences between the both met...

Currents were elicited by acetylcholine (ACh), by d-tubocurarine (dTC), and by mixtures of ACh and dTC, from stably transformed fibroblasts that express fetal or adult muscle nicotinic receptors. dTC acted as an antagonist of ACh for activation of adult-type receptors, whereas it acted as a weak partial agonist at fetal-type receptors. The channel-blocking action of dTC was not apparent at the ...

DTC is strategy of selecting proper stator voltage vectors to reduce torque error and flux error. DTC uses hysteresis band controller whose control action has no difference between large torque error and small one. This results in high torque ripple. In order to reduce the torque ripple and to improve the performance of DTC, DTC based on Fuzzy Logic is proposed in this paper. The simulations ar...

PURPOSE Clinical significance of disseminated tumor cells (DTC) in bone marrow of early breast cancer patients has been reported, but improvements in detection methods are needed. EXPERIMENTAL DESIGN Bone marrow aspirates from 621 patients with stage I to III breast cancer were screened for cytokeratin-positive (CK+) cells. CK+ cells were categorized into DTC only if they had specific morphol...
