IEEE AccessWe present a real-time, diffraction-aware sound–effect framework for VR/game environments that balances physical plausibility and computational efficiency. The core idea is to approximate obstacle-induced wave behavior by (i) interior curl vectors

Application of Artificial Neural Networks to Ship Detection from X-Band Kompsat-5 Imagery
Applied Sciences, 2017 For ship detection, X-band synthetic aperture radar (SAR) imagery provides very useful data, in that ship targets look much brighter than surrounding sea clutter due to the corner-reflection effect. However, there are many phenomena which bring out false

Unfolding homoclinic connections formed by corner intersections in piecewise-smooth maps [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2016 The stable and unstable manifolds of an invariant set of a piecewise-smooth map are themselves piecewise-smooth. Consequently, as parameters of a piecewise-smooth map are varied, an invariant set can develop a homoclinic connection when its stable manifold intersects a non-differentiable point of its unstable manifold (or vice-versa).

Interface Engineering via Sb2Te3 Deposition Enables High‐Performance SWCNT Film Thermoelectrics
Advanced Functional Materials, EarlyView.SWCNTs are promising for flexible thermoelectrics but suffer from low performance. Here, cold‐pressed SWCNT films combined with deposited Sb2Te3 form engineered interfaces that enhance charge transport and energy filtering. The composite achieves a high power factor (25.82 µW cm−1 K−2) and delivers a power density of 3 mW cm−2 at ΔT = 40 K, with ...

Efficiency improvement and evaluation of a centrifugal pump with vaned diffuser
Advances in Mechanical Engineering, 2019 In order to enhance the efficiency of centrifugal pump, the structure of a centrifugal pump with vaned diffuser, whose specific speed is 190, was numerically improved by trimming back-blades of impeller and smoothing sharp corner in annular chamber.

Electro-osmotic non-isothermal flow in rectangular channels with smoothed corners
Thermal Science and Engineering Progress, 2020 Microchannel heat sinks are able to provide high cooling capabilities in terms of heat flux rates. This makes them particularly interesting for the thermal management of electronic devices, owing to the latter’s ever-increasing compactness and, consequently, power density.
