A genetic algorithm for constructing bijective substitution boxes with high nonlinearity
Information Sciences, 2020Substitution box (S-box) is one of the most important components in the design of block ciphers. In this work, different from traditional methods, we convert the construction of n × n S-box into a process of putting n Boolean functions one by one into a ...

The performance of an optical hyperlens made of metal-dielectric layers can be improved by incorporating self-focusing nonlinearity in the dielectric layers. Using a modified beam propagation method in cylindrical coordinates, we show increased bandwidth and better propagation length, which can improve the spatial and temporal resolution of the device.

Summary: We consider a gossip-based distributed stochastic approximation scheme wherein processors situated at the nodes of a connected graph perform stochastic approximation algorithms, modified further by an additive interaction term equal to a weighted average of iterates at neighboring nodes along the lines of ``gossip'' algorithms.

Adaptive Second-Order Sliding-Mode Observer for PMSM Sensorless Control Considering VSI Nonlinearity
IEEE transactions on power electronics, 2018This paper proposes an adaptive super-twisting algorithm based sliding-mode observer (STA-SMO) for surface-mounted permanent magnet synchronous machine (PMSM) sensorless control, in which voltage source inverter (VSI) nonlinearity is taken into ...

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2012
The nonlinear channelizer is an integrated circuit made up of large parallel arrays of analog nonlinear oscillators, which, collectively, serve as a broad-spectrum analyzer with the ability to receive complex signals containing multiple frequencies and instantaneously lock-on or respond to a received signal in a few oscillation cycles.

Nonlinear Computation will provide a framework for the computational science and engineering of the future. Topics such as bifurcation and chaos, and methods such as continuation and branch switching, and features such as stability and sensitivity are basic ingredients in the attempt to understand our world. Nonlinear Computation is indispensable when

Combination tones (CT's) produced by two-tone stimuli (f1 and f2) at relatively low sound levels contradict the classical view that auditory mechanics is an essentially linear process that suffers significant percentage distortion only at high sound levels.

New solitons solutions of the complex Ginzburg-Landau equation with Kerr law nonlinearity
Optik (Stuttgart), 2018In this paper, we find new solitons solutions of the complex Ginzburg-Landau equation with Kerr law nonlinearity according to the new extended direct algebraic method. When parameters involving this method are taken to be special values we can obtain the

This paper presents a broad and well-written account of some major features of nonlinear optics. It sketches the development - via the discovery of laser - of optics from a linear science to todays highly nonlinear research field, displaying the full and enormously rich phenomenology characterizing this area.
