Strength of materials
An electromagnetic field also EM field is a classical i. The electromagnetic field propagates at the speed of light in fact, this field can be identified as light and interacts with charges and currents. Its quantum counterpart is one of the four fundamental forces of nature the others are gravitation , weak interaction and strong interaction. The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges currents ; these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz force law. From a classical perspective in the history of electromagnetism , the electromagnetic field can be regarded as a smooth, continuous field , propagated in a wavelike manner.
Almost all the structures in the fields of practical engineering are applied with various kinds of holes, for example, there are manholes in the plane wings. When the structures are subject to loads, the stress concentration will appear around the holes, which will reduce both the static strength and the fatigue strength. In this paper, in view of the orthotropic plate with manholes, the calculation model was established based on complex function, and the analytic solution of hole-edge stress of orthotropic plate with complex hole shape was figured out. By virtue of mapping function, the parametric equation which accurately describes hole boundary was obtained. As a result, based on the established model, under different fiber array, the holeedge stress of composite material plate with wing manholes was calculated, and stress distributions around the holes under two kinds of fiber array were compared. Thus this study provides theoretical reference for design of flywheel. Keywords: exact analytic solutions of stress on hole edge; orthotropic; opening problems; different fiber arrays; wing manhole; elastic solution.

Applied Strength of Materials for Engineering Technology
Magnetic memories are of great importance for cryogenic platforms that can enable exascale computing, or control of large-scale superconducting quantum processors. Most magnetic memory elements do not perform well at low temperatures, however, and cannot be interfaced directly with superconducting logic schemes. This study demonstrates that spin-orbit-torque devices can be combined with nanoconstriction elements to produce a memory cell that retains the high accuracies and fast switching speeds seen in room-temperature magnetic devices, offering a solution for main memory and cache in high-performance and beyond-Moore computing platforms. When designing a metamaterial, to obtain excellent resonance characteristics the dissipative loss of subcomponents usually should be minimized. However, this study takes the opposite approach and harnesses the dissipation.
Спереди на него быстро надвигалась стена. Такси все еще продолжало крутиться, и в ожидании столкновения он сжался в комок. Раздался оглушающий треск гофрированного металла. Но Беккер не ощутил боли.
Таких посланий она получила больше двух десятков. И все был подписаны одинаково: Любовь без воска. Она просила его открыть скрытый смысл этих слов, но Дэвид отказывался и только улыбался: Из нас двоих ты криптограф. Главный криптограф АНБ испробовала все - подмену букв, шифровальные квадраты, даже анаграммы.
