The negative-bias temperature instability (NBTI) is a reliability problem that, in the last ten years, has risen from relative obscurity to become the most important reliability problem in advanced pMOSFET devices. Even though a significant effort has been

Rapid advances in semiconductor manufacturing and associated technologies have increased the need for optical characterization techniques for materials analysis and in-situ monitoring/control applications. Optical measurements have many unique and

A series of experiments designed to characterize fire spread and growth on flat samples of commercial non-fire-retarded flexible polyurethane foam have been performed. 1.2 m × 1.2 m square sections of foam were ignited along one edge, and the fire spread
We introduce a solver and preconditioning technique based on Domain Decomposition and the Fast Diagonalization Method that can be applied to tensor product based discretizations of the steady convection-diffusion equation. The method is based on iterative
This study compared random and t-way combinatorial inputs of a network simulator, to determine if these two approaches produce significantly different deadlock detection for varying network configurations. Modeling deadlock detection is important for
REFLEAK simulates leak and recharge processes for refrigerant zeotropic mixtures, and estimates composition changes for vapor and liquid under either isothermal or adiabatic leak conditions. Calculated vapor and liquid compositions are displayed in a

Low channel mobility is one of the biggest challenges to commercializing SiC MOSFETs. Accurate mobility measurement is essential for understanding the mechanisms that lead to low mobility. The most widely used effective mobility measurements overestimate

The hydration products of varying proportions of portland cement, fly ash, ground granulated blast furnace slag, and silica fume in blended systems were identified and quantified. The proportion of portland cement varied from 100 % down to 10 %. The
We describe three gravimetric methods for accurately measuring the mass of picoliter-sized fluid droplets generated by a piezoelectric drop-on-demand (DOD) dispenser. Optical methods are also described for co-measurement of droplet diameters. Droplets are
C-reactive protein (CRP) is a serum analyte of clinical interest in ranges which are difficult to detect using standard mass spectrometry approaches. This paper describes a measurement procedure utilizing affinity purification of intact CRP prior to

The spectral irradiance responsivity calibrations of InSb radiometers measured on the tunable-laser based Infrared Spectral Irradiance and Radiance Responsivity Calibration with Uniform Sources (IR-SIRCUS) facility are discussed. This work describes the

We have measured the temperature dependence of spin-torque-driven self-oscillations in point-contact nanooscillators for both in-plane and out-of-plane applied fields. We find that the linewidth for both field geometries is qualitatively similar. In the
A major aerospace company operates large factories that involve thousands of component parts, subassemblies, major sub-systems, tools, fixtures, and material handling equipments to assemble commercial airplanes every day. They are considered mobile assets
The Common Vulnerability Scoring System (CVSS) is a specification that is used to measure the relative severity of software vulnerabilities. CVSS version 2, which was finalized in June 2007, was designed to address several deficiencies discovered during
The National Institute of Standards and Technology (NIST) is leading an effort to develop performance standards for ur- ban search and rescue robots (US&R). An important com- ponent of developing performance standards for these robots is capturing ground
The purpose of this study is to develop relevant metrology to measure the appropriate structure-property relationship at a proper length scale to understand the interplay between nanoparticle and polymeric matrix. In this paper, we present the preliminary
This report concerns the theoretical and practical issues with automatically populating mobile devices with reference test data for use as reference materials in validation of forensic tools. It describes an application and data set developed to populate
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains
Provides some first-order techniques for analyzing matcher performance. A novel argument is used to derive the power-law as a kind of baseline for analyzing matcher performance. The power-law is then applied to two situations: a) CMC curves, and b) fusion
