Abstract Dynamic irradiation is a potent option to influence the interaction between photochemical reactions and mass transport design high performant efficient processes. To systematically investigate impact of this parameter, photocatalytic reduction nitrobenzene was conducted as test reaction. realized through provoked secondary flow patterns, multiple spatially distributed light emitting di...

Extraction of filled-in information from document images in the presence of template poses challenges due to geometrical distortion. Filled-in document image consists of null background, general information foreground and vital information imposed layer. Template document image consists of null background and general information foreground layer. In this paper a novel document image registratio...

We study subvarieties of the flag variety called Hessenberg varieties, defined by certain linear conditions. These subvarieties arise naturally in applications including geometric representation theory, number theory, and numerical analysis. We describe completely the homology of Hessenberg varieties over GLn(C) and show that they have no odd-dimensional homology. We provide an explicit geometr...

z /[ANY physicians appear to be too strict and particular in the rules of diet and regimen, which they deliver as proper to be observed by all who are solicitous either to preserve or recover their health. The too anxious attention to these rules hath often hurt those who are well, and added unnecessarily to the distresses of the sick."' These are the opening sentences of William Heberden's Com...

Attempts to measure the Hubble Constant (H 0) began in the 1920's, and continue today, 70 years later. Obviously, progress was made in those rst 3{4 decades without the beneet of computers. It has become evident during the past 10 years, though, that eeorts to measure H 0 accurately require highly evolved instruments/telescopes, observing procedures, and reduction and analysis tools. Stressful ...

This paper presents a series of experiments focused on the displacement viscoplastic fluids by various Newtonian and non-Newtonian from long horizontal, eccentric annulus. The flow regimes range high Reynolds number laminar through to fully turbulent. These represent primary cementing operation in horizontal well. main objective our is gain insight into role regime fluid-fluid flows relevance c...
