From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Dynamic, capability-driven scheduling of DAG-based real-time jobs in heterogeneous cluster [PDF]

, 2004
In this research a scenario is assumed where periodic real-time jobs are being run on a heterogeneous cluster of computers, and new aperiodic parallel real-time jobs, modelled by Directed Acyclic Graphs (DAG), arrive at the system dynamically.

Tunability of spin-valley polarizations and magnetoresistance in a silicene monolayer modulated by electric and magnetic fields

Materials & Design
We investigate spin–valley polarization, transmittance, and tunneling magnetoresistance (TMR) in an aperiodic structure composed of a silicene monolayer under external magnetic and electrostatic fields.

Control Design Based on Generalized Lur'e Lyapunov Functions for Sampled‐Data Lur'e Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article addresses the synthesis of stabilizing control laws for aperiodic sampled‐data Lur'e systems. Based on a hybrid system representation of the closed‐loop system and a timer‐dependent generalized Lur'e–Postnikov type Lyapunov function, stabilization conditions are obtained by separating decision variables with the application of two

Synthesis of FEEDFORWARD COMPENSATOR in the combined SYSTEM OF AUTOMATIC control WITH PID-REGULATION ON the main CHANNEL circuit

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
An automatic control system for the 1st order aperiodic object is suggested. The structural scheme includes main control circuit with a PID-regulator in it and a disturbance compensation circuit realized by two additional PID-regulators.

Gradient‐ and Newton‐Based Unit Vector Extremum Seeking Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper proposes new methods for stable and efficient convergence in multivariable extremum seeking control (ESC) using sliding mode techniques. Inspired by classical sliding modes and finite‐time control, the approach integrates these ideas into gradient‐ and Newton‐based ESC schemes with sinusoidal perturbations.

Machine Learnability as a Measure of Order in Aperiodic Sequences

CoRR
Research on the distribution of prime numbers has revealed a dual character: deterministic in definition yet exhibiting statistical behavior reminiscent of random processes. In this paper we show that it is possible to use an image-focused machine learning model to measure the comparative regularity of prime number fields at specific regions of an Ulam

INVERSE CORRECTION OF FOURIER TRANSFORMS FOR ONE-DIMENSIONAL STRONGLY SCATTERING APERIODIC LATTICES

Journal of Fundamental and Applied Sciences, 2016
The accuracy of the Fourier transform (FT), advantageous for the aperiodic lattice (AL) design, is significantly improved for strongly scattering periodic lattices (PLs) and ALs.
