This paper presents a comparative study on two most popular control strategies for Permanent Magnet Synchronous Motor (PMSM) drives: field-oriented control (FOC) and direct torque control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System B...

BACKGROUND Effective management of trauma-related invasive fungal wound infections (IFIs) depends on early diagnosis and timely initiation of treatment. We evaluated the utility of routine staining, histochemical stains and frozen section for fungal element identification. METHODS A total of 383 histopathological specimens collected from 66 combat-injured United States military personnel with...

We describe a case of a preterm newborn with congenital complete atrioventricular block (CAVB), delivered for distress by cesarean section, and undergone, at 1295 grams of weight, to permanent pacemaker implantation. The pacemaker has been inserted between the upper left rectus abdominal muscle and the posterior rectus sheath and connected by two epicardial leads on the left ventricle wall. The...

To determine the efficacy of a new method called by us as "gross intra-operative evaluation (GIE)" for the assessment of surgical margin (SM) status. A total of 26 consecutive patients operated with cT1a-b renal tumors at a single center were included in this study. After the excision, the tumors were uniformly divided into two halves in the longitudinal axis ex vivo. In this way, margins were ...

Background: Enchondroma is the most frequent bone tumor of the hand, but chondrosarcoma is rare at this location. There is a high possibility of correct diagnosis of enchondroma and differentiating from its malignant counterpart by precise clinical and radiologic assessment without biopsy, a subject of debate in the literature. At the present study we substantially investigate this problem, in ...
