DFR-Net: Density Feature Refinement Network for Image Dehazing Utilizing Haze Density Difference [PDF]

open access: yes, 2023
In image dehazing task, haze density is a key feature and affects the performance of dehazing methods. However, some of the existing methods lack a comparative image to measure densities, and others create intermediate results but lack the exploitation of their density differences, which can facilitate perception of density.

Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density.

open access: yesPhysical Review B (Condensed Matter), 1988
A correlation-energy formula due to Colle and Salvetti [Theor. Chim. Acta 37, 329 (1975)], in which the correlation energy density is expressed in terms of the electron density and a Laplacian of the second-order Hartree-Fock density matrix, is restated ...

Comparison between Nanosecond Pulse and Direct Current Electrocoagulation for Textile Wastewater Treatment

open access: yesJournal of Water and Environment Technology, 2020
This paper proposes the utilization of a nanosecond pulsed (NSP) power supply in the electrocoagulation (EC) system for textile wastewater treatment. Four aluminum plates arranged in a monopolar-parallel configuration are utilized as electrodes in a 200 ...

A Universal Density Profile from Hierarchical Clustering [PDF]

open access: yes, 1996
We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape, independent of the halo mass, the initial density ...

A tabletop, ultrashort pulse photoneutron source driven by electrons from laser wakefield acceleration

open access: yesMatter and Radiation at Extremes, 2017
Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources. The experiment was carried out on the 38 fs, ∼0.5 J, 800 nm Ti:Sapphire laser in the 10 TW UT3 laser lab at University of Texas at ...
