A planar plasma antenna with a dielectric coat [PDF]

open access: yesРадиофизика и электроника, 2020
Subject and Purpose. The coefficients of surface wave energy transformation to radiation and the radiation patterns are calculated for an open structure like a planar longitudinally inhomogeneous plasma layer located in between a metal layer and a ...

Homogeneous nonequilibrium molecular dynamics method for heat transport and spectral decomposition with many-body potentials [PDF]

open access: yesPhysical review B, 2018
The standard equilibrium Green--Kubo and nonequilibrium molecular dynamics (MD) methods for computing thermal transport coefficients in solids typically require relatively long simulation times and large system sizes.

Assessment of four strain energy decomposition methods for phase field fracture models using quasi-static and dynamic benchmark cases

open access: yesMaterials Theory, 2022
Strain energy decomposition methods in phase field fracture models separate strain energy that contributes to fracture from that which does not. However, various decomposition methods have been proposed in the literature, and it can be difficult to ...

Mach-Zehnder Interferometer Sensor Curvature Demodulation Method Based on the Orthogonal Decomposition of Spectral Curves

open access: yesIEEE Access, 2020
This paper proposes a curvature demodulation of Mach-Zehnder interferometer (MZI) sensors based on complete spectral information. An MZI sensor composed of two waist-enlarged single mode fibers (SMFs) was fabricated.

Spectral division methods for block generalized Schur decompositions [PDF]

open access: yesMathematics of Computation, 2004
We provide a different perspective of the spectral division methods for block generalized Schur decompositions of matrix pairs. The new approach exposes more algebraic structures of the successive matrix pairs in the spectral division iterations and reveals some potential computational difficulties.

Mathematical delay model based on QS with hyperexponential and Erlang distributions

open access: yesФизика волновых процессов и радиотехнические системы, 2022
This article is devoted to the study and obtaining a closed-form solution for the average delay of claims in the queue for a queuing system formed by two flows with hyperexponential and Erlang distributions of intervals.

Model parameter estimations of the multi-channel turbulence response from flutter flight tests based on autoregressive spectra

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2023
Signal processing of flutter flight test data enables verification of aircraft flutter design, and the signal from a flutter flight test excited by atmospheric turbulence is a particularly important form of the flutter test.

Spectral solution for a delay system with hyper-Erlang distributions

open access: yesФизика волновых процессов и радиотехнические системы, 2022
The article is devoted to the construction of a mathematical model for delaying claims in a queue in the form of a queuing system described by two flows with the laws of distribution of time intervals shifted to the right by hyper-Erlang distributions of
