Scientific considerations presented in this paper are related to the methods for power loss minimization in induction motor drives. The induction motor is without doubt the most used electrical motor and a great energy consumer. Three-phase induction motors consume 60% of industrial electricity and it takes considerable efforts to improve their efficiency (Vukosavic, 1998). The vast majority of...

This article introduces a new configuration of the doubly-fed induction generator (DFIG) based wind energy conversion system (WECS) employing only reduced-size rotor side converter (RSC) in tandem with supercapacitor. In proposed structure, grid (GSC) utilized conventional DFIG-based WECSs is successfully eliminated. accomplished by hydraulic transmission (HTS) as continuously variable and shaf...

As the demand for eco-friendly energy increases, hydrogen and liquid storage technologies are being developed as an alternative. Hydrogen has a lower liquefaction point higher thermal conductivity than nitrogen or neon used in general cryogenic systems. Therefore, application of to systems can increase efficiency stability. This paper describes design analysis cooling system electric propulsion...

One potential advantage of the application of superconducting materials in electrical machines is the possibility to build lighter and compact devices by removing iron. These machines find applications, e.g., in systems where cryogenics is already available, or in naturally cryogenic environments. The design of motors with high temperature superconductors (HTS) presents issues unconsidered in c...

several approaches are available to reduce pulsating torque components in permanent magnet motors. one of the known techniques is stator tooth shape modifications. this paper presents an integrated algorithm applicable for tooth shape optimization of permanent magnet motors. this method focuses on the reduced basis technique, finite element analysis and taguchi method and is conducted on tooth ...

Acute kidney injury (AKI) occurs both after traumatic brain injury (TBI) and after hypertonic saline administration; furosemide may be useful in preventing AKI indirectly. Serum neutrophil gelatinase-associated lipocalin (sNGAL) is superior to serum creatinine (sCr) in diagnosing early AKI. We compared the administration of hypertonic saline plus furosemide (HTS+F) versus hypertonic saline (HTS...

The molecular mechanism of high-temperature stress (HTS) response, in plants, has so far been investigated using transcriptomics, while the dynamics HTS-responsive proteome remain unexplored. We examined adaptive responses resilient wheat cultivar ‘Unnat Halna’ and dissected landscape. This led to identification 55 proteins (HRPs), which are predominantly involved metabolism defense pathways. I...
