QUANTUM BREMSSTRAHLUNG IN ALMOST UNIFORM FIELDS [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989
Abstract Inhomogeneity effects in quantum bremsstrahlung, in the case of a weakly nonuniform deflecting field, are calculated in the extreme quantum limit.

Field Evaluation of Microirrigation Water Application Uniformity

open access: yesEDIS, 2012
This publication presents procedures to separately evaluate the effects of pressure variations in the pipe network (hydraulic uniformity) and variations due to the emitter characteristics (emitter performance variation) on uniformity of water ...

Numerical Investigation and Optimization of Cooling Flow Field Design for Proton Exchange Membrane Fuel Cell

open access: yesEnergies, 2022
High temperatures and non-uniform temperatures both have a negative bearing on the performance of proton exchange membrane fuel cells. The temperature of proton exchange membrane fuel cells can be lowered by reasonably distributed cooling channels.

Fermions on tori in uniform Abelian fields [PDF]

open access: yesPhysical Review D, 2002
We study Fermi fields defined on tori in the presence of gauge backgrounds carrying non-trivial topology. We show that 2k dimensional field space can alternatively be described by fields over a k-dimensional space. This dual description is particularly natural when the background is uniform and abelian.

The Effect of Zigzag Boundaries on the Reverberation Chamber Performance

open access: yesIEEE Access, 2021
The stirrer design is important in a reverberation chamber measurement system. Previous study shows that the rotating radius of the stirrer plays a key role for the stirrer performance. However, to identify the contribution from the structure, optimizing

Flow analysis and uniformity evaluation of the exhaust pipeline of a marine diesel engine

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives]In a marine diesel engine,the SCR reactor's NOx conversion efficiency is effected by the flow field uniformity at the inlet. In order to optimize the design of the exhaust pipeline of the diesel engine and the improve the SCR reactor's ...

A spatially uniform illumination source for widefield multi-spectral optical microscopy.

open access: yesPLoS ONE, 2023
Illumination uniformity is a critical parameter for excitation and data extraction quality in widefield biological imaging applications. However, typical imaging systems suffer from spatial and spectral non-uniformity due to non-ideal optical elements ...
