We study representations of piecewise-smooth signals on graphs. We first define classes for smooth, piecewise-constant, and piecewise-smooth graph signals, followed by a series of multiresolution ...

The design of piecewise-linear switching functions is investigated for linear, constant, lumped systems with a single ideal relay controller with respect to a transient response (minimum-time) ...

where A is a Vandermonde matrix. 3.1 Piecewise Polynomial Interpolation A quite natural and different approach to approximate a function on an interval is to first split the interval into subintervals ...

In this problem, the optimal path is one that maximizes the expected utility, with the utility function being piecewise-linear and concave. Such a utility function can be used to approximate nonlinear ...

Abstract We present wavelet bases made of piecewise (low degree) polynomial functions with an (arbitrary) assigned number of vanishing moments. We study some of the properties of these wavelet bases; ...

Research based around a simple yet fascinating, repetitive piecewise function. This repository contains multiple scripts that help explore and perform tests on numbers to try and prove the ...
