The service system design problem arises in the design of telecommunication networks, refuse collection and disposal networks in public sector, transportation planning, and location of emergency medical facilities. The problem seeks to locate service facilities, determine their capacities and assign users to those facilities under time varying demand(More)
Gilbert's syndrome, caused by relative deficiency of glucuronyl transferase is the commonest cause of congenital hyperbilirubinemia. We report anesthetic management in a case of Gilbert's syndrome for laparoscopic cholecystectomy under general anesthesia. Avoiding drugs which use this enzyme for its metabolisim or excretion, and minimizing the stress during(More)
The effective hydrodynamic size and free mobility of particles of varying aspect ratio were evaluated by Ferguson analysis of gel electrophoresis. The ligand layer thickness was estimated from the difference between the effective size and the size of the metal core from TEM imaging. The zeta potential of the particles was calculated from the Ferguson(More)
The multi-hour bandwidth packing problem arises in telecommunication networks that spans several time horizon. The problem seeks to select and route a set of messages from a given list of messages with prespecified requirement on demand for band-width under time varying traffic conditions on an undirected communication network such that the total profit is(More)
In this paper, we model the evolution and self-assembly of randomly oriented carbon nanotubes (CNTs), grown on a metallic substrate in the form of a thin film for field emission under diode configuration. Despite high output, the current in such a thin film device often decays drastically. The present paper is focused on understanding this problem. A(More)
Owing to their distinct properties, carbon nanotubes (CNTs) have emerged as promising candidate for field emission devices. It has been found experimentally that the results related to the field emission performance show variability. The design of an efficient field emitting device requires the analysis of the variabilities with a systematic and(More)
