Thermal mode of a room with integrated regulation of cooling systems

open access: yesMagazine of Civil Engineering, 2021
An air-conditioned room with automatic regulation of the climate systems serving it using complex control algorithms is one of the most difficult objects for calculating non-stationary thermal regime, so to date, this method is insufficiently studied. At

Characterizing the statistical distribution for transmission coefficient of turbulent optical orbital-angular-momentum channels.

open access: yesOptics Express, 2019
The instantaneous transmission coefficient, i.e., instantaneous transmittance, of a turbulent optical orbital-angular-momentum (OAM) channel is mathematically formulated as a weighted integration and is found to range between 0 and 1.

Bound state eigenvalues from transmission coefficients [PDF]

open access: yesEuropean Journal of Physics, 2021
Abstract Experts know that bound state energy eigenvalues of a potential well are poles of its transmission amplitude, t ( E ). The textbooks do well by solving the bound states and scattering states separately, but the connection goes

Estimation of S-Parameters and Dielectric Permittivity of Polycor and GaAs Samples Using a Vector Network Analyzer

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2023
To study the S-parameters and dielectric permittivity of polycor and GaAs samples, a vector network analyzer R4-MWM-118 with a special measuring cell and a modified Nicholson–Ross–Weir method were used.

An Impact Location Method Based on Transmission Coefficient Weighted Impact Intensity

open access: yesIEEE Access, 2020
The stiffened plate has complex influences on the propagation characteristics of Lamb waves, which causes difficulties for the impact location. In order to realize the impact location in stiffened plate, this paper proposes a transmission coefficient ...

A local scattering theory for the effects of isolated roughness on boundary-layer instability and transition: transmission coefficient as an eigenvalue

open access: yesJournal of Fluid Mechanics, 2016
This paper is concerned with the rather broad issue of the impact of abrupt changes (such as isolated roughness, gaps and local suctions) on boundary-layer transition.
