In this paper, we present first, second, and third order implicit finite-volume solvers for advectiondiffusion problems based on the first-order hyperbolic system method. In particular, we demonstrate that the construction of an uniformly accurate third-order advection-diffusion scheme is made trivial by the hyperbolic method while a naive construction of adding a third-order diffusion scheme t...

A novel approach for reducing power consumption in checkers used for concurrent error detection is presented. Spatial correlations between the outputs of the circuit that drives the primary inputs of the checker are analyzed to order them such that switching activity (and hence power consumption) in the checker is minimized. The reduction in power consumption comes at no additional impact to ar...

Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid decentralisation and integration of intermittent, renewable power sources, which lead to more variability and uncertainty in the system. Today,...

Abstract. The main advantage of inverse iteration over the QR algorithm and Divide & Conquer for the symmetric tridiagonal eigenproblem is that subsets of eigenpairs can be computed at reduced cost. The MRRR algorithm (MRRR = Multiple Relatively Robust Representations) is a clever variant of inverse iteration without the need for reorthogonalization. stegr, the current version of MRRR in LAPACK...

The main challenge during night-time driving is the visibility of the road ahead. The major challenge rests in controlling accidents during night as the night conditions differ from the day in environment conditions, vehicle lighting etc. The reduced cost of cameras and optical devices helped in installing front-mounted intelligent systems for identifying forward collision avoidance and mitigat...

This paper discusses the safety challenges faced by railroads in the United States. It discusses and evaluates public policy dealing with trespassing, grade crossing collisions, occupational injuries and operational accidents. The primary conclusion is that the government oversight body, the Federal Railroad Administration (FRA), should take on the role of teacher and risk analyst rather than t...

VOLUME 37 • AUGUST 2012 • www.mrs.org/bulletin © 2012 Materials Research Society Plasmonics: Converting photons into the nanoscale Recently, photonic technologies have become universal in global data communications. 1 The unprecedented data bandwidths, ever falling power consumption requirements, and reduced cost margins of on-chip photonics 2,3 have established a photonic roadmap for scaling d...

The Information Fusion Journal (IFJ), an Elsevier publication, is planning a special issue devoted to Localized Algorithms for Information Fusion in Resource-Constrained Networks. Resource-Constrained Networks (RCNs) include a wide variety of networks in which resources – such as processing, communication, and energy – are limited. Examples of RCNs include ad hoc networks, sensor networks, mobi...

Given increased global competition and consumers’ increasing price sensitivity, apparel retailers such as J. C. Penney have begun to focus on quick response and cycle time reduction as part of their overall business strategy. Extensive use of interorganizational linkages with major suppliers has become a key component in designing more effective, responsive strategies to meet changing corporate...

In embedded systems, memory is one of the most expensive resources. Due to this, program code size has turned out to be one of the most critical design constraints. Code compression is one of the approaches to reduce the program code size; it results in smaller memories and reduced cost of the chip. Furthermore, code compression can decrease the power consumption of the chip. In this paper, a c...
