Several reference materials and associated reference values have been recommended for the purposes of calibration and/or validation of differential scanning calorimetry (DSC). However, issues of available sample purity, reference-property value accuracy
Cloud computing is the next step in the continued evolution of information systems. Cloud computing allows consumers to choose what and how they want services delivered and provides billing based on usage. The resources pooling and rapid provisioning of
Paper cut-out cube, 10 cm on each side listing metric conversion information on each face covering units of length, mass or weight, area or surface, energy, volume and temperature. The bottom face lists common metric prefixes.
In this paper we introduce an approach to construct statistical metrology tools with a Microsoft Excel based interface that use the open source statistical package R as the computational engine. These metrology tools will enable Excel users to access a
We demonstrate a method to trap a selected dielectric microparticle in air using radiation pressure from a single-beam gradient optical trap. Randomly scattered dielectric microparticles adhered to a glass substrate are momentarily detached using

In October 2009, the International Organization for Standardization (ISO)/ International Electrotechnical Commission (IEC) Joint Technical Committee 1 (JTC 1) reconstituted the Study Group (SG) on Digital Content Management and Protection (SGDCMP) with
This note gives an interpretation of Dobrushin?s conditions for uniqueness and mixing Markov field in terms of a random walk with an absorbing state. An example involving Ising?s lattice gas model is discussed, and a version of the Central Limit Theorem is
This paper aims at improving the power efficiency of the CSMA/CA protocol for transmission of multimedia information over multihop wireless channels. Using a distance dependent propagation model, we present a power control scheme, which is based on the
Calculating the force on a reference mass for the electronic kilogram experiment requires using both absolute and relative gravity meters to measure the acceleration of gravity. Tests have been conducted to achieve an uncertainty of less than 1 part in 108

This paper presents the first evaluation of Spoken Term Detection technologies, held during the latter part of 2006. Spoken Term Detection systems rapidly detect the presence of a term, which is a sequence of words consecutively spoken, in a large audio
The Sixth International Comparison of Absolute Gravimeters was held from 2 July to 28 August 2001 at the Bureau International des Poids et Mesures (BIPM), S'vres. Seventeen absolute gravimeters were used to make measurements at five sites of the BIPM
Software assurance tools examine code for problems. To test such tools, we need programs with known bugs as ground truth. The Software Assurance Reference Dataset (SARD) is a publicly accessible collection of over 100,000 test cases in different

Self-compacting concrete (SCC) has become a technological preferred option for many projects that should satisfy strict fresh stage properties that are of major concern in quality assurance. To ensure stable and robust fresh stage properties, typically a
Jacob Rabinow holds 230 U.S. patents on a variety of mechanical and electrical devices. Among these are the automatic letter-sorting machine used by the U.S. Post Office, the magnetic particle clutch, formerly used in several European automobiles, in
Analysis of molecular mass distribution data for characterizing the complex synthetic polymer structure has demanded new statistical methods. As with many other high throughput measurement devices, typically only very small number of replicates can be
Book Review for: Stochastic Ageing and Dependence for Reliability, by Chin-Diew Lai and Min Xie, New York: Springer-Verlag, 2006 ISBN-10: 0-387-29742-1 and ISBN-13: 978-0387-29742-2, xx+418 pp., $100

Pre-oxidation of the bottom electrode prior to deposition of Al_{2}O_{3} or MgO is very effective as a general approach to suppressing the unidirectional coupling that is commonly observed in magnetic tunnel junctions. In this paper, we report structural
A commercial silicon powder was studied by x-ray photoelectron spectroscopy (XPS) and x-ray induced Auger electron spectroscopy (XAES). These techniques were used to determine the oxidation kinetics for this powder in the temperature range from 600 to 750

Pre-oxidation of the bottom electrode prior to deposition of Al2O3 or MgO is very effective as a general approach to suppressing orange-peel coupling in magnetic tunnel junctions. In this paper, we report structural studies on this effect using grazing
This work has two objectives. The first objective is to introduce structural engineers to the experiment design technique, whose future applications may include, among others: the total response of tall buildings, and the nonlinear response to failure of

This paper is a summary of the first CLEAR evaluation on CLassification of Events, Activities and Relationships - which took place in early 2006 and concluded with a two day evaluation workshop in April 2006. CLEAR is an international effort to evaluate
