Thrust ripple and density greatly impact the performance of linear machine other actuators, causing positioning control precision, dynamic performance, efficiency issues. Generalized pole-pair combinations are difficult to satisfy both thrust for double salient reluctance machines. In this paper, a DC-Biased vernier (DCB-VRLM) is proposed solve abovementioned The key design reduce enhance with ...

Beach erosion is a natural phenomenon that not compensated by depositing fresh material on the shoreline while transporting sand away from shoreline. There are three phenomena have serious influence coastal structure, such as increases in flooding, accretion, and water levels. In addition, prediction of evolution used to investigate topography beach. this research, we present one-dimensional ma...
