We construct nonlinear extensions of Dirac's relativistic electron equation that preserve its other desirable properties such as locality, separability, conservation of probability and Poincaré ...

If one has a set of observables (z1, ··· , zm) which are bound in a relation with certain parameters (a1, ··· , an) by an equation &zgr;(z1, ··· , a1, ···) = 0, one frequently has the problem of ...

Abstract: With an emphasis on nonlinear models for energy harvesting (EH), this article examines nonlinear approaches in advanced optimization for simultaneous wireless information and power transfer ...

This work investigates the perturbed nonlinear Schrödinger equation using the modified -expansion method. The obtained results are generalized and classified into classes of trigonometric, hyperbolic, ...

Simultaneous Suspension Control and Energy Harvesting through Novel Design and Control of a New Nonlinear Energy Harvesting Shock Absorber. (arXiv:2106.10540v2 [eess.SY] UPDATED) Simultaneous ...

A basic Newton-Raphson type nonlinear equation solver for sparse or dense systems with m functions of n input variables. Is object-oriented. Works with square, under-determined, or over-determined ...

ABSTRACT: Steady state plastic flow of the ideal plastic half-space surface by sliding elliptical cylinder is numerically calculated with account of contact friction effect. Numerical solution of the ...

ABSTRACT: The Heun functions have wide application in modern physics and are expected to succeed the hypergeometrical functions in the physical problems of the 21st century. The numerical work with ...

Abstract: We introduce a new modified nonlinear simultaneous equation model to handle uneven data and proves the large-sample properties (the consistency and the asymptotic normality) of the maximum ...
