Human visual system is partially adapted to the CRT monitor’s white point and partially to the ambient light, when comparing a soft-copy image with the reproduced hard-copy image. The visual experiments were performed on the effect of the ambient lighting under mixed chromatic adaptation. It was found that human visual system is 40% to 60% adapted to CRT monitor’s white point and the rest to th...
We prove that the united K-theory functor is a surjective functor from the category of real simple purely infinite C*-algebras to the category of countable acyclic CRT-modules.
Color images are usually viewed on CRT monitor screen under ambient light sources. The feeling for reproduced color on CRT monitor depends on white point of ambient light source and the CRT monitor screen'-3. Therefore, if the effect of ambient light source is not considered, then the reproduced color does not match the intrinsic color. This paper proposes a method to investigate the effect of ...
This application claims an invention which was disclosed in Provisional Application Number 60/108,100, filed November 12, 1998, entitled "Desktop Projector". The benefit under 35 USC §119(e) of the United States provisional application is hereby claimed.. 5 This application is also a continuation-in-part of Serial No. 09/323,651, filed June 1, 1999, which is also a PCT International Application...
We are currently constructing a new X-ray absorption fine structure (XAFS) beamline BL36XU at SPring-8 dedicated for the structural and electronic analysis of the dynamic events on polymer electrolyte fuel cell (PEFC) cathode catalysts for the development of next-generation PEFCs. To investigate the cathode catalyst nanoparticles in PEFCs under the operating conditions, the beamline is designed...
The effect of an 80 nm YSZ interfacial layer, deposited onto a YSZ pellet by different techniques (dip-coating, sputtering and atomic layer deposition) at the SOFC cathode/electrolyte interface to allow a maximum adhesion of the thick cathode layer, was thoroughly analysed. The LSM cathode was deposited on the solid electrolyte by painting and sintered in air at 1200°C for 2 h. The morphologica...
An electrochemically-active high-temperature form of LiCoO2 (HT-LiCoO2) is prepared by thermally decomposing its constituent metal-nitrates at 700 oC. The synthetic conditions have been optimized to achieve improved performance with the HT-LiCoO2 cathode in Li-ion batteries. For this purpose, the synthesized materials have been characterized by powder X-ray diffraction, scanning electron micros...
Systematical studies of the electrochemical performance of CF x -derived carbon-FeF2 nanocomposites for reversible lithium storage are presented. The conversion cathode materials were synthesized by a simple one-pot synthesis, which enables a reactive intercalation of nanoscale Fe particles in a CF x matrix, and the reaction of these components to an electrically conductive C-FeF2 compound. The...
Schottky CdTe X-ray detectors exhibit excellent spectroscopic performance but suffer from instabilities. Hence it is of extreme relevance to investigate their electrical properties. A systematic study of the electric field distribution and the current flowing in such detectors under optical perturbations is presented here. The detector response is explored by varying experimental parameters, su...
Criterion-free forced-choice procedures for measuring contrast sensitivity with a cathode ray tube (CRT) have low within-subject, intersubject, and test-retest variabilities, but a long test time compared with psychophysical methods that rely on the subject's criterion to determine threshold. Test time and variability of criterion-dependent methods depend on the rate at which the contrast chang...
