This research deals with a hybrid flow shop scheduling problem with parallel batching, machine eligibility, unrelated parallel machine, and different release dates to minimize the sum of the total weighted earliness and tardiness (ET) penalties. In parallel batching situation, it is supposed that number of machine in some stages are able to perform a certain number of jobs simultaneously. First...

This paper presents the design of a hybrid excited flux switching Vernier machine. machine is designed to serve in renewable energy conversion applications, such as wind turbine generator, or tidal generator. After introducing this original structure, based on finite element models conducted. The specifications correspond relatively low power direct drive applications. rated set 10 kW, with spe...

according to recent developments of predicting methodsin financial markets, and since the stock price is one of the mostimportant factors for investment decision-making, and its predictioncan play an important role in this field, the aim of this study is toprovide a model to predict the stock price movement with highaccuracy. accordingly, a hybrid model for predicting the stock pricemovement us...

This paper describes the application of static var compensators, (SVC) on an electrical distribution network containing two large synchronous motors, one of which is excited via a three-phase thyristor bridge rectifier. The second machine is excited via a diode bridge rectifier. Based on linear optimization control (LOC), the measurable feedback signals are applied to the control system loops o...

A hybrid-excited doubly salient dual-PM machine (HE-DSDPM) was presented by using the structural multi-tooth modification for an improvement of torque production. The structure HE-DSDPM clearly described. PM and stator arcs were further examined optimization. electromagnetic performance including magnetic flux distribution, linkage, back-electromotive force (back-EMF), total harmonic distortion...

This article proposes a doubly salient machine (DSM) with subslot bottom permanent magnets (PMs) to enhance the torque production. The key is that auxiliary slot-PM excitation, stator yoke dc saturation can be mitigated production capability of field meanwhile additional flux pushed into airgap, which build parallel excitation and generate effective torque. Comparing dc-excited DSM represents P...
