Modeling of LED using Piecewise Linear Approximation and Maclaurin series Expansion
2018 2nd IEEE International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2018LED is a light emitting semiconductor device which is nowadays, swiftly replacing conventional lighting system, owing to its high intensity and low energy consumption. In order to understand the operating characteristics of LED, its modeling is required. The very basic modeling of LED can be done by considering it as a resistor.

APPROXIMATING THE DENSITY OF THE TIME TO RUIN VIA FOURIER-COSINE SERIES EXPANSION
ASTIN Bulletin, 2016AbstractIn this paper, the density of the time to ruin is studied in the context of the classical compound Poisson risk model. Both one-dimensional and two-dimensional Fourier-cosine series expansions are used to approximate the density of the time to ruin, and the approximation errors are also obtained.

From high oscillation to rapid approximation II: expansions in Birkhoff series
IMA Journal of Numerical Analysis, 2011We consider the use of eigenfunctions of polyharmonic operators, equipped with homogeneous Neumann boundary conditions, to approximate nonperiodic functions in compact intervals. Such expansions feature a number of advantages in comparison with classical Fourier series, including uniform convergence and more rapid decay of expansion coefficients ...

Series Expansion Approximants for Singular Functions of Many Variables
1977A novel method of approximating functions of two or more variables given a finite number of coefficients of their power series expansions is explained. The method — partial differential approximation — is effective in representing the characteristic singularities to be expected in functions of two or more variables (typically those arising in ...
