Analysis on High-Power Seaport LED Luminaire with Uniform Light Distribution Based on Optimized Lens and Heatsink

open access: yesApplied Sciences, 2021
In the case of light-emitting diode (LED) seaport luminaires, they should be designed in consideration of glare, average illuminance, and overall uniformity.

Parton Saturation at Small x and in Large Nuclei [PDF]

open access: yes, 1999
Quark and gluon distributions in the light-cone wavefunction of a high energy hadron or nucleus are calculated in the saturation regime. One loop calculations are performed explicitly using the equivalence between the parton distribution in the light ...

Exploring the Vertical Distribution of Structural Parameters and Light Radiation in Rice Canopies by the Coupling Model and Remote Sensing

open access: yesRemote Sensing, 2015
Canopy structural parameters and light radiation are important for evaluating the light use efficiency and grain yield of crops. Their spatial variation within canopies and temporal variation over growth stages could be simulated using dynamic models ...

Optimal Design of Plant Canopy Based on Light Interception: A Case Study With Loquat

open access: yesFrontiers in Plant Science, 2019
Canopy architecture determines the light distribution and light interception in the canopy. Reasonable shaping and pruning can optimize tree structure; maximize the utilization of land, space and light energy; and lay the foundation for achieving early ...

Light-cone distribution amplitudes of the baryon octet [PDF]

open access: yes, 2016
We present results of the first ab initio lattice QCD calculation of the normalization constants and first moments of the leading twist distribution amplitudes of the full baryon octet, corresponding to the small transverse distance limit of the ...

Six-dimensional light-front Wigner distribution of hadrons

open access: yesPhysics Letters B, 2022
We propose a six-dimensional light-front Wigner distribution for the complete description of partonic structures of a hadron such as pion and proton, taking advantage of the recently proposed light-front variable z˜ by Miller and Brodsky.

GMLight: Lighting Estimation via Geometric Distribution Approximation [PDF]

open access: yesIEEE Transactions on Image Processing, 2022
Inferring the scene illumination from a single image is an essential yet challenging task in computer vision and computer graphics. Existing works estimate lighting by regressing representative illumination parameters or generating illumination maps directly. However, these methods often suffer from poor accuracy and generalization. This paper presents

Light-cone distribution amplitudes of light mesons with QED effects

open access: yesJournal of High Energy Physics, 2021
We discuss the generalization of the leading-twist light-cone distribution amplitude for light mesons including QED effects. This generalization was introduced to describe virtual collinear photon exchanges at the strong-interaction scale ΛQCD in the ...
