This paper addresses four different aspects of the remote sensing image fusion: i) image fusion method, ii) quality analysis of fusion results, iii) effects of image decomposition level, and iv) importance of image registration. First, a new contourlet-based image fusion method is presented, which is an improvement over the wavelet-based fusion. This fusion method is then utilized withinthe mai...

SHARP (Simulation-based High-efficiency Advanced Reactor Prototyping) is a modern suite of codes to simulate the key components of a fast reactor core. The SHARP toolkit is organized as a collection of modules, each representing the key components of the physics to be modeled – neutron transport, thermal hydraulics, fuel/structure behavior – together with pre and post-processing for geometry de...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.

conclusions the relatively high prevalence of percutaneous injuries and splashes in this study emphasized the importance of improved prevention strategies, better hospital surveillance for occupational exposure, and enhanced training of healthcare workers. background healthcare workers (hcws) regularly face the risk of exposure to sharp injuries and splashes as an occupational hazard, which pre...

Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purp...
