Single kick approximations for beam-beam deflections

Physical Review Special Topics. Accelerators and Beams, 1999
A six-dimensional symplectic beam-beam interaction map using finite discrete slices of a strong beam is extended to infinitesimal slices. The new map is calculated under the assumption of a longitudinal Gaussian distribution with approximations.

Finite element analysis for microscale heat equation with Neumann boundary conditions [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this paper, we explore the numerical analysis of the microscale heat equation. We present the characteristics of numerical solutions obtained through both semi- and fully-discrete linear finite element methods.

Approximate calculation of 8-point DCT for various scenarios of practical applications

EURASIP Journal on Image and Video Processing, 2021
In this paper, based on the parametric model of the matrix of discrete cosine transform (DCT), and using an exhaustive search of the parameters’ space, we seek for the best approximations of 8-point DCT at the given computational complexities by taking ...

Accuracy of Approximation for Discrete Distributions [PDF]

Journal of Probability and Statistics, 2016
The paper is a contribution to the problem of estimating the deviation of two discrete probability distributions in terms of the supremum distance between their generating functions over the interval [0,1]. Deviation can be measured by the difference of the kth terms or by total variation distance.
