Recursive Heaviside step functions and beginning of the universe

New Astronomy, 2017
Abstract This article introduces recursive Heaviside step functions, as a potential of the known universe, for the first time in the history of mathematics, science, and engineering. In modern cosmology, various bouncing models have been suggested based on the postulation that the current universe is the result of the collapse of a previous universe.

Excitation of medium by Heaviside step function of electric field

2016 10th European Conference on Antennas and Propagation (EuCAP), 2016
An analytical solution in a closed form to the problem of excitation of a medium by Heaviside step function of electric field has been obtained. It allows for studying fields excited by impulse (non-smooth) sources. Numerical results of fields' calculation in a medium are presented.

Derivative of Heaviside step function vs. delta function in continuum surface force (CSF) models

International Journal of Multiphase Flow, 2018
Abstract In Continuum Surface Force (CSF) model for implementing surface tension forces in multiphase flows, singular delta function is used to merge two continuous sets of flow equations. Discretizing the delta function has attracted a great deal of attention and has led to developing many different approaches. It has been shown numerically that two

Analysis and Design of a $k$-Winners-Take-All Model With a Single State Variable and the Heaviside Step Activation Function

IEEE Transactions on Neural Networks, 2010
This paper presents a k-winners-take-all (kWTA) neural network with a single state variable and a hard-limiting activation function. First, following several kWTA problem formulations, related existing kWTA networks are reviewed. Then, the kWTA model model with a single state variable and a Heaviside step activation function is described and its global
