Sensors, 2012 In structural vibration tests, one of the main factors which disturb the reliability and accuracy of the results are the noise signals encountered. To overcome this deficiency, this paper presents a discrete wavelet transform (DWT) approach to denoise ...

Advanced Materials Technologies, EarlyView.A machine learning platform is developed to optimize sliced images for digital light processing 3D printing by locally tuning light intensity for higher precision printing. A reduced‐order model accurately predicts the degree of conversion in 3D space to calculate resulting shapes.

Characterization of a Class of Sigmoid Functions with Applications to Neural Networks
Neural Networks, 1996 We study two classes of sigmoids: the simple sigmoids, defined to be odd, asymptotically bounded, completely monotone functions in one variable, and the hyperbolic sigmoids, a proper subset of simple sigmoids and a natural generalization of the hyperbolic tangent. We obtain a complete characterization for the inverses of hyperbolic sigmoids using Euler'

High Contrast and High Efficiency Optical Weighting for Integrated Photonic Computing
Advanced Optical Materials, EarlyView.Herein, a combined pulse optical weighting scheme is proposed for photonic synapses. Employing a 4 μm$\umu{\rm m}$ long non‐volatile phase‐change material covered on a straight waveguide, a transmission contrast of 31.2 dB is achieved. By exploiting the non‐Arrhenius behavior of the material, the crystallization energy is reduced to 107 pJ, with ...

C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination
Advanced Optical Materials, EarlyView.This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...

Advanced Optical Materials, EarlyView.We demonstrate ultra‐fast and efficient electro‐optical switching using the isotropic phase of ferroelectric nematic liquid crystals. A moderate electric field induces a transition to polar ferroelectric nematic order, producing large field‐induced birefringence with sub‐microsecond switch‐on and switch‐off times. This advance enables new opportunities
