Groundwater quality in Hyderabad has special significance and needs great attention of all concerned since it is the major alternate source of domestic, industrial and drinking water supply. The present study monitors the ground water quality, relates it to the land use / land cover and maps such quality using Remote sensing and GIS techniques for a part of Hyderabad metropolis. Thematic maps f...

International EMC standards describe the measurement environment (setup, equipment, frequencies) and applicable limits for the electromagnetic emission testing of lighting equipment, including compact fluorescent lamps (CFLs). These standards consider the compact fluorescent lamp a ‘black box’. In order to better understand the emissions from this type of light source, the operation of the equi...

We report closed-loop results obtained from the first adaptive optics system to deploy multiple laser guide beacons. The system is mounted on the 6.5 m MMT telescope in Arizona, and is designed to explore advanced altitudeconjugated techniques for wide-field image compensation. Five beacons are made by Rayleigh scattering of laser beams at 532 nm integrated over a range from 20 to 29 km by dyna...

The Windy Postman Problem consists of finding a minimum cost traversal of all the edges of an undirected graph with two costs associated with each edge, representing the costs of traversing it in each direction. In this paper we deal with the Windy General Routing Problem (WGRP), in which only a subset of edges must be traversed and a subset of vertices must be visited. This is also an NP-hard ...

ii The cover image is based on a photograph of arc spots moving on the surface of a Ti cathode, taken during the first experimental session in our new PVD research system, Hydra. The explosive plasma generation in the arc spots is central to the cathodic arc deposition technique, studied and used extensively for synthesis in the Thesis. Abstract This Thesis explores the arc deposition process a...

Magnetic fields permeate the interstellar medium and are important in star formation process. Determining 3D magnetic of molecular clouds will allow us to better understand their role evolution these stars. We fully reconstruct approximate three-dimensional (3D) field morphology Orion A cloud (on scales a few ~100 pc) using Galactic models, as well present line-of-sight plane-of-sky observation...

Unmitigated arc-faults present fire dangers, shock hazards, and cause system downtime in photovoltaic (PV) systems. The 2011 National Electrical Code® added section 690.11 to require a listed arc-fault protection device on new PV systems. Underwriters Laboratories created the outline of investigation for PV DC arc-fault circuit protection, UL 1699B, for certifying arc-fault circuit interrupters...

The feedback arc set problem plays a prominent role in the four-phase framework to draw directed graphs, also known as the Sugiyama algorithm. It is equivalent to the linear arrangement problem where the vertices of a graph are ordered from left to right and the backward arcs form the feedback arc set. In this paper we extend classical sorting algorithms to heuristics for the feedback arc set p...

Regulation of feeding behavior has been a crucial step in the interplay between leptin and the arcuate nucleus of the hypothalamus (ARC). On one hand, the basic mechanisms regulating central and peripheral action of leptin are becoming increasingly clear. On the other hand, knowledge on how brain sensitivity to leptin can be modulated is only beginning to accumulate. This point is of paramount ...
