To realize the brush-less operation for wound field vernier machines (WFVMs), a novel self-excited topology is proposed in this paper which involves four-pole main armature winding and two-pole excitation connected series using an uncontrolled rectifier. Upon supplying current from single current-controlled voltage source inverter (VSI), procedure results magnetomotive force (MMF) components ai...
It is common for placenames to reference other named entities (e.g., names of people, names of organizations, etc.) and to be used as vocabulary words (e.g., city of Split). Apart from reference ambiguity, placenames are faced with the problem of referent ambiguity (i.e., a placename referring to multiple places). Many places are also referred to by multiple names (e.g., Netherlands vs. Holland...
Among the other dwarf galaxies with violent star formation IC10 galaxy stands out for anomalously high number of Wolf-Rayet (WR) stars. For instance, the number of WR-stars in IC10 is 20 times higher than that in LMC and spatial density of WR stars in IC10 reaches 11 WR stars per square kpc (Massey et al., 2002 [8], Massey et al., 2007 [7], Crowther et al., 2003 [4] and references in these pape...
Dipeptides absorbed by the intestinal epithelium are delivered to circulation, but their metabolic roles are not yet clearly understood. We investigated the biological activities of a dietary dipeptide, H-Trp-Arg-OH (WR), on the regulation of peroxisome proliferator-activated receptor (PPAR) α activity. Reporter gene assays revealed that WR dose-dependently induced PPARα transactivation. Surfac...
This paper offers a novel dual-mode double stator wound rotor synchronous machine for variable speed applications. The proposed motor integrates the benefits of both traditional (WRSM) and brushless (BL-WRSM). A constant torque can be attained in maximum per ampere region by operating as WRSM Mode I, power field-weakening it BL-WRSM II. Moreover, due to dual-stator structure, exhibits improved ...
PURPOSE To determine the clinical characteristics, prognosis, and treatment outcome for patients with nasal natural killer (NK)/T-cell lymphoma (N-NKTL) and Waldeyer ring NK/T-cell lymphoma (WR-NKTL). EXPERIMENTAL DESIGN A total of 145 patients with N-NKTL and 95 patients with WR-NKTL were compared. RESULTS Compared with N-NKTL, WR-NKTL exhibited distinct differences in clinical features wi...
Induction machines are perhaps the most widely used of all electric motors. They are generally simple to build and rugged, offer reasonable asynchronous performance: a manageable torque-speed curve, stable operation under load, and generally satisfactory efficiency. Because they are so widely used, they are worth understanding. In addition to their current economic importance, induction motors ...
