MEASURING THE IMPACT OF EDUCATION AND TRAINING

January 15, 2013
Author(s)
Georgia L. Harris
As metrologists we are typically subject matter experts (SMEs) in a technical area of measurement. However, most of us are not experts in measuring the value or impact of education and training efforts using standard models for evaluation. This paper will

Self-aligned multi-channel silicon nanowire field-effect transistors

December 12, 2012
Author(s)
Hao Zhu, Qiliang Li, Hui Yuan, Helmut Baumgart, D. E. Ioannou, Curt A. Richter
Si nanowire field effect transistors (SiNW FETs) with multiple nanowire channels and different gate lengths have been fabricated by using a directed assembly approach combined with standard photolithographic process. The electrical characteristics of SiNW

A Grassmann Manifold-based Domain Adaptation Approach

November 20, 2012
Author(s)
P J. Phillips, Jingjing Zheng, Ming-Yu Liu, Rama Chellappa
Domain adaptation algorithms that handle shifts in the distribution between training and testing data are receiving much attention in computer vision. Recently, a Grassmann manifold-based domain adaptation algorithm that models the domain shift using

Broadband Emissivity Calibration of Highly Reflective Samples at Cryogenic Temperatures

October 15, 2012
Author(s)
Solomon I. Woods, Timothy M. Jung, Greg Ly, Simon G. Kaplan, Jie Yu
We have developed a technique for calibrating the broadband optical emissivity of high reflectivity samples at cryogenic temperatures. This measurement method employs a primary standard optical detector with high absorptance from visible wavelengths to

Concrete rheometers

May 1, 2012
Author(s)
Chiara C. Ferraris, Nicos Martys
The scope of this chapter is to introduce the current technology for measuring the rheological properties of concrete. The need to evaluate or assess the flow properties of concrete has resulted in the invention or design and standardization of hundreds of

Criteria Towards Metrics for Benchmarking Template Protection Algorithms

March 30, 2012
Author(s)
Eddy Simoens, Bian Yang, Xuebing Zhou, Filipe Beato, Christoph Busch, Elaine M. Newton, Bart Preneel
Traditional criteria used in biometric performance evaluation do not cover all the performance aspects of biometric template protection (BTP) and the lack of well-defined metrics inhibits the proper evaluation of such methods. Previous work in the

High Temperature Seebeck Coefficient Metrology

December 22, 2010
Author(s)
Joshua B. Martin, Terry M. Tritt, Winnie K. Wong-Ng, Ctirad Uher
We present an overview of the challenges and practices of thermoelectric metrology at high temperature (300 K-1300 K). The Seebeck coefficient, when combined with thermal and electrical conductivity, is a useful property measurement for evaluating the
