Cluster-driven non-uniform characteristic analysis of underwater target acoustic scattering field

open access: yesFrontiers in Physics
Underwater small targets typically exhibit non-centrosymmetric geometries, resulting in a highly spatially inhomogeneous acoustic scattering field under active sonar detection.

Decomposition of Acoustic and Entropy Modes in a Non-Isothermal Gas Affected by a Mass Force

open access: yesArchives of Acoustics, 2018
Diagnostics and decomposition of atmospheric disturbances in a planar flow are considered in this work. The study examines a situation in which the stationary equilibrium temperature of a gas may depend on the vertical coordinate due to external forces ...

Local magnetic measurements in magnetic circuits with highly nonuniform electromagnetic fields [PDF]

open access: yes, 2009
In this paper, local magnetic measurements are carried out in magnetic circuits with highly non uniform electromagnetic field patterns, including excitation winding and/or air gaps, as in the case of rotating electrical machines.

Approximate Methods for Calculating a Non-Uniform Travelling Field

open access: yesIEEJ Transactions on Fundamentals and Materials, 1975
Abstract The approximation methods for calculating the non-uniform travelling field, which is formed by a series of parallel cylindrical electrodes located at equal intervals on a plane and applied with balanced three-phase voltage, are presented. The substitute-charge method using line-charges located inside the cylinders as their substitute-charges

A Metamaterial-like Structure Design Using Non-uniformly Distributed Dielectric and Conducting Strips to Boost the RF Field Distribution in 7 T MRI

open access: yesSensors
Metamaterial-based designs in ultra-high field (≥7 T) MRI have the promise of increasing the local magnetic resonance imaging (MRI) signal and potentially even the global efficiency of both the radiofrequency (RF) transmit and receive resonators.

DYNAMICS OF MAGNETIC FLUID CAPILLARY RISE IN POROUS MEDIUM

open access: yesНаука. Инновации. Технологии, 2022
Bstract: In the present work the capillary flow of magnetic fluid in a single cylindrical capillary and in a porous medium under the action of a non-uniform magnetic field is studied experimentally. The dynamics of the capillary rise has been considered.

Phase-field modeling for investigating the effect of rebar positioning and uniform versus non-uniform corrosion on concrete fracture

open access: yesFracture and Structural Integrity
Rebar corrosion significantly affects the overall performance and the service life of reinforced concrete (RC) structures due to the reduction in the bond strength between concrete and rebar, leading to the delamination of the concrete cover.

Stochastic modeling of plasmonic field evolution propagating in non-uniform metallic strip arrays

open access: yesResults in Optics
The amplitude field distribution of surface plasmons propagating in an array of non-uniform metallic strips is analyzed. The study models the evolution of the amplitude function as a Markov chain, which is associated with a stochastic matrix.
