this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

We present a method for removal of the contaminating effects of intrinsic galaxy alignments, in measurements of cosmic shear from multicolour weak lensing surveys. The method down-weights pairs which are likely to be close in three dimensions, based on spectroscopic or photometric redshifts. Results are dramatic: the intrinsic contamination of the low-redshift Sloan photometric redshift survey ...

Abstract Aiming to extract efficiently the fault features of partial discharge in process diagnosis power transformer, a method combining Empirical Wavelet Transform (EWT) with Multiscale Permutation Entropy (MPE) is advanced transformers discharge. Firstly, four different pulse signals are analyzed by EWT method, and signal decomposed according frequency domain characteristics obtain intrinsic...

Abstract In this paper we study a family of limsup sets that are defined using iterated function systems. Our main result is an analogue Khintchine’s theorem for these sets. We then apply to the topic intrinsic Diophantine Approximation on self-similar particular, define new height element $${\mathbb {Q}}^d$$ <mml:m...
