In this work, various emerging core and winding materials suitable for a high frequency planar transformer (PT) has been analyzed compared. Core used in significant effect mostly the losses of transformer. Emerging like amorphous nanocrystalline cores were compared against conventional ferrite core. The results obtained showed that reduced by around 48.14% on using or instead cores. Typical cop...

While the electromagnetic aspects of hairpin windings are actively being investigated and discussed in recent literature, including design rules together with loss calculation reduction techniques, thermal performance modeling have received less attention to date. In windings, conductors (pins) comparatively larger arranged as separate components parallel within slot. contrast, randomly overlap...

Nowadays, one of the key challenges in transport electrification is reduction components’ size and weight. The electrical machine plays a relevant role this regard. Designing machines with higher rotational speeds excitation frequencies most effective solutions to increase power densities, but comes at cost increased losses cores windings. This challenge even more pronounced preformed windings,...

I consider an argument, due to Geoffrey Lee, that we can know a priori from the leftright asymmetrical character of experience that our brains are left-right asymmetrical. Lee’s argument assumes a premise he calls relationism, which I show is well-supported by the best philosophical picture of spacetime. I explain why Lee’s relationism is compatible with left-right asymmetrical laws. I then sho...

AbstractIn the present study, attempt has been made to examine the effectiveness of peer and teacher scaffolding in reading comprehension of intermediate EFL students in symmetrical and asymmetrical groups. To do so, sixty intermediate students were purposively selected out of 150 intermediate students in Hamadan Islamic Azad University and Kish Language Institute in Hamadan. They were divided ...

We address the problem of unsupervised and language-pair independent alignment of symmetrical and asymmetrical parallel corpora. Asymmetrical parallel corpora contain a large proportion of 1-to-0/0-to-1 and 1-to-many/many-to-1 sentence correspondences. We have developed a novel approach which is fast and allows us to achieve high accuracy in terms of F1 for the alignment of both asymmetrical an...

This paper investigates the potential benefits of utilizing superconducting materials in machines. The project focuses on replacing conventional copper windings with a machine. machine is modelled and simulated using ANSYS software, both windings. A 3.7kw 11kw 3 phase Induction machines are YBCO material applied to stator rotor results show that use can significantly reduce energy losses improv...
