Analysis of the behaviour of the Brushless Doubly Fed Machine (BDFM) has received considerable attention in the literature. The BDFM is typified by its complex airgap flux distribution. This paper will build upon performance-prediction work, concentrating on the design and electromagnetic behaviour of the BDFM rotor, considering 2 different sizes of 4/8-pole stator machines and comparing test r...

PURPOSE The purpose of the present study was to compare pole and no-pole conditions during uphill backpacking, which was simulated on an inclined treadmill with a moderately heavy (22.4 kg, 30% body mass) backpack. METHODS Physiological measurements of oxygen consumption, heart rate, and RPE were taken during 1 h of backpacking in each condition, along with joint kinematic and electromyograph...

We show that if f is a transcendental meromorphic function with a finite number of poles and f has a cycle of Baker domains of period p, then there exist C > 1 and r0 > 0 such { z : 1 C r < |z| < Cr } sing(f−p) ∅, for r r0. We also give examples to show that this result fails for transcendental meromorphic functions with infinitely many poles.

Using the South Pole Acoustic Test Setup (SPATS) and a retrievable transmitter deployed in holes drilled for the IceCube experiment, we have measured the attenuation of acoustic signals by South Pole ice at depths between 190 m and 500 m. Three data sets, using different acoustic sources, have been analyzed and give consistent results. The method with the smallest systematic uncertainties yield...

this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...

When the external branch of superior laryngeal nerve (EBSLN) crosses the superior thyroid artery closer to thyroid upper pole, the EBSLN has a higher risk of getting damaged. Its anatomical position in relation to thyroid upper pole may vary with changing the height of patient and the length of larynx. We intended to test this hypothesis and predict the risk. Thirty cadavers of both sexes are d...

This work presents an application of Linear Matrix Inequalities (LMI) for the robust control of an F-16 aircraft through an algorithm ensuring the damping factor to the closed loop system. The results show that the zero and gain settings are sufficient to ensure robust performance and stability with respect to various operating points. The technique used is the pole placement, which aims to put...

Inductance profile has an important bearing on the performance of a Switched Reluctance Motor (SRM) This paper presents the results of a frequency respolse method to estimate the inductance profde of SRMs. Stator winding is energized by a variable voltage variable Frequency supply. An approximate equivalent circuit incorporating stator resistance, winding inductance and loss component has been ...

The reusability of decommissioned treated wood is primarily dependent on the residual strength of the wood after service. Determining the residual strength can provide useful information for structural design and reuse of the decommissioned treated wood. This study evaluated the residual strength of decommissioned chromated copper arsenate-treated utility pole wood. Eleven decommissioned southe...
