Study of the magnetocaloric effect in (Pr,Dy)2Fe17 and Pr2(Fe,Al)17 intermetallic compounds

The Pr2Fe17 compound is a potential candidate for low cost magnetocaloric materials with a significant relative cooling power (RCP) around room temperature (280 K). In this work, we present the results of the substitution of dysprosium for…

Control And Operating Point Optimization Of Hybrid Excitation Synchronous Generator Applied For Wind Application

The purpose of this paper is to evaluate the possibilities of hybrid excitation synchronous generator (HESG) for wind applications. In HESG, excitation flux is created by both permanent magnets and excitation coils, so the output voltage can be…

Design of piezoelectric transformer-based DC/DC converter to improve power by using heat transfer equipment

In this paper, we propose a new design of a piezoelectric transformer (PT) for low-profile DC/DC converter applications , which increases the output power by using heat transfer equipment. We examined several parameters, which allow us to produce a…

Fast multilinear Singular Values Decomposition for higher-order Hankel tensors

The Higher-Order Singular Value Decomposition (HOSVD) is a possible generalization of the Singular Value Decomposition (SVD) to tensors, which have been successfully applied in various domains. Unfortunately, this decomposition is computationally…
