Centrins are calmodulin-like proteins present in centrosomes and yeast spindle pole bodies (SPBs) and have essential functions in their duplication. The Saccharomyces cerevisiae centrin, Cdc31p, binds Sfi1p on multiple conserved repeats; both proteins localize to the SPB half-bridge, where the new SPB is assembled. The crystal structures of Sfi1p-centrin complexes containing several repeats sho...
Today’s automotive industry has focused its studies on electric vehicles (EVs) or hybrid (HEVs) rather than gasoline-powered vehicles. For this reason, more investment been made in motors with high efficiency, torque density, and high-power factor to be used both EVs HEVs. In study, an outer-rotor permanent-magnet-assisted synchronous reluctance motor (PMaSynRM) a new rotor topology was designe...
abstract: literature is said beautiful words of poetry or prose that excites reader’s or listener’s feel. certainly, to be effective, such a text should have certain characteristics. the four elements of the literature: thought, imagination, emotion and style make a text to be literary and effective. emotion and imagination are specific elements of literary texts, while thought and style a...
Permanent magnet Vernier motors (PMVMs) possess the advantage of high torque density for high-performance applications. However, low power factor challenge makes it unacceptable direct-drive A lack accurate modeling method based on motor sizing law, i.e., air-gap flux density, linear current and geometry parameters, raises difficulties machine designers to further conduct research performance m...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
In this article, a multiphysics simulation workflow based on the use of reduced-order models to decrease computation time is presented. Using finite-element (FE) precomputed flux-linkage and lumped force lookup-tables in function dq0 currents rotor position, an electromagnetic model permanent-magnet synchronous machine (PMSM) developed. Coupled mechanical state-space representation, complete al...
The traditional flux reversal permanent magnet (FRPM) machine has high torque ripple due to the double salient-pole structure, and effective air-gap length is increased by structure of stator tooth surface, which affects size magnetomotive force (MMF). This paper proposes an axial modular flux-reversal (AM-FRPM) with attractive capabilities. Based on magnetic field modulation theory, a method a...
abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
Diaphragm fishways are often used in fishway engineering construction. Although there an increasing number of new types fishways, other diaphragm can be derived from the combination or evolution following three basic fishways: vertical slot, overflow weir and orifice. To compare hydraulic characteristics different foundation operations slot orifice calculated by numerical simulation, we compreh...
