This paper proposes a novel brushless synchronous machine topology that utilizes stator sub-harmonic magnetomotive force (MMF) for desirable operation. The MMF component is used in this one fourth of the fundamental component, whereas, previous practices, it was half. To achieve operation, uses unique winding configuration two sets balanced 3-phase wound 3 layers. For rotor, additional placed t...

Weedy rice (WR) is found in many direct-seeded rice fields. WR possesses morphological characteristics that are similar to cultivated rice varieties in the early stage of growth, making them more difficult to control than other weeds. A comparative morphological study was conducted by collecting WR accessions from four sites within the Pulau Pinang rice growing areas. The objective of the study...

This paper presents a data-driven co-reference resolution system for German that has been adapted from IMS HotCoref, a co-reference resolver for English. It describes the difficulties when resolving co-reference in German text, the adaptation process and the features designed to address linguistic challenges brought forth by German. We report performance on the reference dataset TüBa-D/Z and in...

most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...

This paper introduces a topology for achieving the brushless operation of wound rotor vernier motor using single-phase additional winding on stator, specifically designed variable-speed applications e.g., washing machines. In proposed topology, stator consists two sets: four-pole three-phase main and an two-pole winding. On other hand, contains 44-pole field to generate effect, excitation induc...

This paper presents a new online method based on low frequency signal injection to estimate the stator resistance of Wound Rotor Synchronous Machine (WRSM). The proposed estimator provides parameter-free for estimating resistance, in which there is no need know values parameters machine model, such as and rotor inductances or flux linkage. In this method, sinusoidal current injected d axis prod...
