Advanced Functional Materials, EarlyView.Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

The Journal of the Acoustical Society of America, 1971 The two traditional broad-band fan noise generation mechanisms are “noise due to incident turbulence” and “noise due to vortex shedding.” These might be called “aerodynamicists' mechanisms,” since they are both rooted in fluctuating lift concepts derived from two-dimensional incompressible unsteady aerofoil theory.

Journal of Low Frequency Noise, Vibration and Active Control, 2018 In this study, some of the optimal parameters for a new-style marine axial flow fan are defined by using numerical simulation and experimental tests with a large marine axial flow fan, based on the analysis of the blade perforation’s influences on its ...

Vibroacoustic Optimization Study for the Volute Casing of a Centrifugal Fan
Applied Sciences, 2019 A numerical optimization is presented to reduce the vibrational noise of a centrifugal fan volute. Minimal vibrational radiated sound power was considered as the aim of the optimization.

Advanced Functional Materials, EarlyView.This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

The Noise Problem in the Application of Fans [PDF]
The Journal of the Acoustical Society of America, 1935 This paper stresses the noise elements in the application of fans, particularly those of the propeller type, where the apparatus must operate in quiet surroundings. The sources of such noise are divided into the inherent noise of the fan, and the five classes of noise which tend to modify this inherent noise as follows: (1) Noise increase due to ...

Fiber‐Based Wearable Electronics as Adaptive Biointerfaces for Healthcare Applications
Advanced Functional Materials, EarlyView.Fiber‐based wearable electronics have been extensively studied as adaptive healthcare biointerfaces. In this review, we classify and introduce fiber‐based systems according to biointerface design, conductive materials, transduction mechanisms, and healthcare applications, and provide a perspective on their translation toward reliable, continuous ...

Noise from Centrifugal Fans [PDF]
The Journal of the Acoustical Society of America, 1955 The sound power radiated from the discharge of centrifugal fans of diameters between 3 and 612 inches has been measured as a function of fan dimensions and operating conditions. The measurements were made by arranging the fan under test to discharge into an 11 foot nonreflecting tube in which the static pressure could be controlled.

Advanced Functional Materials, EarlyView.Mask‐encoded UV exposure translates digital color information into pixel‐resolved structural‐color patterns in hydroxypropyl cellulose gels. Gaussian‐process‐guided calibration links UV processing conditions, wavelength, and mask opacity, enabling parallel fabrication of multicolor images in a single 10 s exposure.
