A new compact scheme for parallel computing using domain decomposition
No full textDirect numerical simulation (DNS) of complex flows require solving the problem on parallel machines using high accuracy schemes. Compact schemes provide very high spectral resolution, while satisfying the physical dispersion relation numerically. However, as shown here, compact schemes also display bias in the direction of convection – often producing numerical instability near the inflow and severely damping the solution, always near the outflow. This does not allow its use for parallel computing using domain decomposition and solving the problem in parallel in different sub-domains. To avoid this, in all reported parallel computations with compact schemes the full domain is treated integrally, while using parallel Thomas algorithm (PTA) or parallel diagonal dominant (PDD) algorithm in different processors with resultant latencies and inefficiencies. For domain decomposition methods using compact scheme in each sub-domain independently, a new class of compact schemes is proposed and specific strategies are developed to remove remaining problems of parallel computing. This is calibrated here for parallel computing by solving one-dimensional wave equation by domain decomposition method. We also provide the error norm with respect to the wavelength of the propagated wave-packet. Next, the advantage of the new compact scheme, on a parallel framework, has been shown by solving three-dimensional unsteady Navier–Stokes equations for flow past a cone-cylinder configuration at a Mach number of 4.Additionally, a test case is conducted on the advection of a vortex for a subsonic case to provide an estimate for the error and parallel efficiency of the method using the proposed compact scheme in multiple processors

Characterization of reconfigurable ultra-narrowband optical filters realized by localized dynamic Brillouin gratings
No full textWe experimentally demonstrate reconfigurable ultra-narrowband optical filters realized by localized dynamic Brillouin gratings in a polarization maintaining fiber. The filters are characterized in terms of bandwidth, optical signal-to-noise ratio and peak to sidelobe ratio

Antiviral Drug Target Identification and Ligand Discovery
No full textThis chapter intends to provide a general overview of web-based resources available for antiviral drug discovery studies. First, we explain how the structure for a potential viral protein target can be obtained and then highlight some of the main considerations in preparing for the application of receptor-based molecular docking techniques. Thereafter, we discuss the resources to search for potential drug candidates (ligands) against this target protein receptor, how to screen them, and preparing their analogue library. We make specific reference to free, online, open-source tools and resources which can be applied for antiviral drug discovery studies. [Abstract copyright: © 2024.

Policy Making in a Terrorist Economy
No full textThis article provides a study of the various sectors of the economy of Jammu and Kashmir since the onset of insurgency in 1990. Such a study
in a milieu of economic uncertainty and government
policies in those settings is extremely important for
a better comprehension of how agents react under
these circumstances. The lessons learnt from such a
study have policy implications and are directly linked
to the possibilities of a peace dividend.not peer reviewedSubmitted by Matt Rosenstein ([email protected]) on 2010-05-11T15:17:25Z
