Sigmoid Function Model for a PWM DC–DC Converter
IEEE transactions on power electronics, 2023Considering the presence of switching devices, a pulse-width modulation (PWM) dc–dc converter is a piecewise smooth switching system that causes difficulties in stability analysis and controller design. Hence, a new modeling method that employs a sigmoid

Generalized born model with a simple smoothing function
Journal of Computational Chemistry, 2003AbstractBased on recent developments in generalized Born (GB) theory that employ rapid volume integration schemes (M. S. Lee, F. R. Salabury, Jr., and C. L. Brooks III, J Chem Phys 2002, 116, 10606) we have recast the calculation of the self‐electrostatic solvation energy to utilize a simple smoothing function at the dielectric boundary. The present GB

VAD Based on Kernel Smoothed Function of EGARCH Models
Wireless Personal Communications, 2013An algorithm for a voice activity detector (VAD) is proposed. It is based on the exponential generalized autoregressive conditional heteroscedasticity (EGARCH) filter for generalized hyperbolic (GH), Gaussian random variables, adaptive threshold values and autocorrelation coefficients.

Smooth Muscle Model For Functional Electrical Stimulation Applications
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007We present a new model of smooth muscle that can be used to simulate the effect of Functional Electrical Stimulation (FES). It is composed of a set of differential equations based on the physiological reality so that parameter's values are meaningful and can be used for quantitative and objective evaluation of the muscle state.

A Piecewise Function Smooth Strength Envelope Model
Applied Mechanics and Materials, 2012The method of trigonometric series is one of widely used methods for calculating artificial ground motion. But using this method the speed of time, it was found that the zero line must exist the phenomenon of drift. This text fore person the foundation of the research up, a kind of more perfect model of differentiable nonsingular strength envelope ...

Smoothness of the Policy Function in Discrete Time Economic Models
Econometrica, 1991Summary: The theory applying to dynamic programming has furnished a useful set of techniques for the analysis of many types of sequential models. This theory, however, has not yielded heretofore much information about the differentiability properties of optimal solutions.
