On Nonlinear Preservers of Weak Matrix Majorization

Nonlinear Dynamics of Buck Converter

This paper is concerned with the problem of modeling and simulation of piecewise linear systems with the pulse width modulation control. Models of this kind of systems are widely used in engineering practice, in particular in power electronic converters. The research provides the study of chaos and bifurcations in one of the switching converters – step-down converter under voltage mode control,...

Nonlinear Instabilities in D2TCP-II

In the era of heavy-duty transmission control protocols (TCP), adapted for extremely hi-bandwidth datacenters; the fundamental question of stable interaction with either proposed/customized active queue management(AQM) or popularly discussed Random Early Detection (RED) remains a hotly debated issue. While there are claims of “oscillation” only dynamical behavior, there are equally large number...

Realization of AC-AC Converter Using Matrix Converter

The aim of this paper is to describe work involved in investigations on the implementation of single phase matrix converter (SPMC) as an AC-AC converter subjected to passive load conditions. The successful implementation of the SPMC had been conceived, designed and realized by synthesizing the output using the well known sinusoidal pulse width modulation (SPWM) technique with IGBTs as power swi...

Instabilities and bifurcations of nonlinear impurity modes.

We study the structure and stability of nonlinear impurity modes in the discrete nonlinear Schrödinger equation with a single on-site nonlinear impurity emphasizing the effects of interplay between discreteness, nonlinearity, and disorder. We show how the interaction of a nonlinear localized mode (a discrete soliton or discrete breather) with a repulsive impurity generates a family of stationar...
