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 ...

Phase Space Engineering in Optical Microcavities I: Preserving near-field uniformity while inducing far-field directionality [PDF]

open access: yes, 2010
Optical microcavities have received much attention over the last decade from different research fields ranging from fundamental issues of cavity QED to specific applications such as microlasers and bio-sensors. A major issue in the latter applications is

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.

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

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 ...

The Dedekind different for a uniform set of points in Pn

open access: yesTạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2022
Given a set of s distinct points X in the projective space Pn over a field K, we are interested in studying the uniformity of X. Explicitly, we work out an algorithm for checking the uniformity of X and we apply the Dedekind different to characterize ...

Formation of uniform magnetic flux distribution for NMR magnets using HTS bulk magnets activated by pulsed-field magnetization

open access: yesMaterials Research Express, 2020
Nuclear magnetic resonance (NMR) magnets generally need an extremely uniform magnetic field in the space where the specimens will be placed. Although high temperature superconducting bulk magnets can obtain an intense magnetic field of more than 3 T, the
