In order to design high performance circuits, the relationship between circuit performance and design parameters must be precisely established. Previously, experimental design techniques have been employed for performance modeling of MOS VLSI devices and circuits. In this paper we describe a new computer-aided methodology for characterizing a family of electrical circuits. This methodology is b...

It is becoming increasingly important to be able to verify the spatial accuracy of precipitation forecasts, especially with the advent of high-resolution Numerical Weather Prediction (NWP) models. In this paper, the Fractions Skill Score (FSS) approach has been used to perform a scale-selective evaluation of precipitation forecasts during 2003 from the Met Office mesoscale model (12 km grid len...

Thermodynamic and dynamic analyses of a variable speed reciprocating compressor have been conducted to investigate performance changes and some data related to the reliability problems such as valve velocity, PV value, bearing loci, Sommerfeld number, minimum film thickness etc. The first law of thermodynamics, continuity equations, valve dynamic equations and Helmholtz resonator method were us...

The verification of a gridded forecast field, for example, one produced by numerical weather prediction (NWP) models, cannot be performed on a gridpoint-by-gridpoint basis; that type of approach would ignore the spatial structures present in both forecast and observation fields, leading to misinformative or noninformative verification results. A variety of methods have been proposed to acknowle...

This paper presented an overview of the tools used to predict ventilation performance in buildings. The tools reviewed were analytical models, empirical models, small-scale experimental models, full-scale experimental models, multizone network models, zonal models, and Computational Fluid Dynamics (CFD) models. This review found that the analytical and empirical models had made minimal contribu...

Due to power and I/O constraints associated with extreme scale scientific simulations, in situ visualization and analysis to will become a critical component to scientific discovery. The options for extreme scale visualization and analysis are often presented as a stark contrast: write files to disk for interactive, exploratory analysis, or perform in situ analysis to save data products about p...

BACKGROUND AND PURPOSE Stroke scales are intended to measure stroke severity for the purpose of clinical trials. Scores have been used to determine trial entry, to compare patient groups within or between trials, or as a secondary end point. The use of scores as an end point in meta-analysis has not been validated, but such analyses have nevertheless been performed when equivocal results have b...

New adaptive structural systems comprised of optimal material combinations, innovative sensors and actuators, and control subsystems need to be developed and tailored for damage tolerant applications associated with severe loading conditions and harsh environments. In this position paper, fundamental considerations related to the modeling, design, and performance prediction of adaptive heteroge...
