WebFeb 15, 2024 · Some incoherent phases always tend to nucleate and grow at grain boundaries, which have a great influence on the magnetic properties of the alloys [38]. HPS will not only promotes the formation of nanoprecipitates in the HEAs, but also affects the morphology, structure and composition distribution of the grain boundary phases [39]. In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow … See more Coherence was originally conceived in connection with Thomas Young's double-slit experiment in optics but is now used in any field that involves waves, such as acoustics, electrical engineering, neuroscience, … See more The coherence of two waves expresses how well correlated the waves are as quantified by the cross-correlation function. Cross-correlation … See more Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a … See more Waves of different frequencies (in light these are different colours) can interfere to form a pulse if they have a fixed relative phase-relationship (see Fourier transform). Conversely, if waves of different frequencies are not coherent, then, when combined, they … See more The coherence function between two signals $${\displaystyle x(t)}$$ and $${\displaystyle y(t)}$$ is defined as where See more These states are unified by the fact that their behavior is described by a wave equation or some generalization thereof. • Waves in a rope (up and down) or slinky (compression and expansion) • Surface waves in a liquid See more In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions. Spatial coherence describes the ability for two points in space, x1 and x2, in the extent of a wave to interfere, when averaged over time. More precisely, the spatial … See more

WebIn electrical engineering, magnetic (iron) transformer cores are used all the time to step up/down the electrical pressure (voltage) of alternating current systems. These cores were once made from single pieces of iron, but nowadays we use many layers of thin metal plates to make the transformer more efficient.
