International Journal of Circuits, Systems and Signal Processing, 2021 This paper discusses the application of local interpolation splines of the second order of approximation for the numerical solution of Volterra integral equations of the second kind. Computational schemes based on the use of polynomial and non-polynomial

Thermoelectric transport of GaAs, InP, and PbTe: Hybrid functional with k · p ̃ interpolation versus scissor-corrected generalized gradient approximation [PDF]
Journal of Applied Physics, 2018 Boltzmann transport calculations based on band structures generated with the density functional theory are often used in the discovery and analysis of thermoelectric materials. In standard implementations, such calculations require dense k-point sampling

On the steady‐state performance of bias‐compensated LMS algorithm
Electronics Letters, 2021 Adaptive filtering algorithms are widespread today owing to their flexibility and simplicity. Due to environments in which they are normally immersed, their robustness against noise has been a topic of interest.

Relativistic Hartree-Bogoliubov Calculation of Specific Heat of the Inner Crust of Neutron Stars [PDF]
, 2001 We calculate the specific heat of the inner crust of neutron stars within a local-density approximation to an improved relativistic Hartree-Bogoliubov theory. Non-uniformness of the system enhances the specific heat in particular at low temperatures. The

Solving Poisson Equations by the MN-Curve Approach
Mathematics, 2022 In this paper, we adopt the choice theory of the shape parameters contained in the smooth radial basis functions to solve Poisson equations. Luh’s choice theory, based on harmonic analysis, is mathematically complicated and applies only to function ...

Density Problem and Approximation Error in Learning Theory
Abstract and Applied Analysis, 2013 We study the density problem and approximation error of reproducing kernel Hilbert spaces for the purpose of learning theory. For a Mercer kernel on a compact metric space (, ), a characterization for the generated reproducing kernel Hilbert space (RKHS)

Mathematical Modeling of COVID-19 Transmission Using a Fractional Order Derivative
Fractal and Fractional, 2022 In this article, the mathematical model of COVID-19 is analyzed in the sense of a fractional order Caputo operator with the consideration of an asymptomatic class. The suggested model is comprised of four compartments. The results from fixed point theory

Approximation of Parametric Derivatives by the Empirical Interpolation Method [PDF]
, 2011 We introduce a general a priori convergence result for the approximation of parametric derivatives of parametrized functions. We consider the best approximations to parametric derivatives in a sequence of approximation spaces generated by a general ...

Quadratic Interpolation and Linear Lifting Design
EURASIP Journal on Image and Video Processing, 2007 A quadratic image interpolation method is stated. The formulation is connected to the optimization of lifting steps. This relation triggers the exploration of several interpolation possibilities within the same context, which uses the theory of convex ...
