Fresh Concrete Rheology - Recent Developments

Author(s)
Chiara F. Ferraris, F De Larrard, Nicos Martys
The design of concrete with specified properties for an application is not a new science, but it has taken on a new meaning with the wide use of high...

Estimating the RMS of a Wavefront and Its Uncertainty

Author(s)
Angela Davies, M. Levenson
The root mean square (RMS) of the surface departure or wavefront deformation is a common value to extract from an optical test. The RMS may be a tolerance an...

H H. Ku, Joan R. Rosenblatt
ginning with the balanced incomplete block designs known as Youden Spuares, W.J. Youden created many designs tailored to the needs of the physical and...

The NIST Speaker Recognition Evaluations: 1996-2001

Author(s)
Alvin F. Martin, Mark A. Przybocki
We discuss the history and purpose of the NIST evaluations of speaker recognition performance. We cover the sites that have participated, the performance...

Hybrid Fractal Zerotree Wavelet Image Coding

Author(s)
R E. Van Dyck, T Kim, D J. Miller
In this paper, a hybrid fractal zerotree wavelet (FZW) image coding algorithm is proposed. The algorithm couples a zerotree-based encoder, such as the embedded...

Crystal Structures of Calcium Orthophosphates

Author(s)
M Mathew, Shozo Takagi
Calcium phosphates comprise the largest group of biominerals in vertebrate animals. They also have many uses in industry, medicine and everyday life...

Octacalcium Phosphate Carboxylates

Author(s)
Milenko Markovic
In the last two decades the interactions of organic molecules with different inorganic minerals have been the focus of considerable biomineralization and...

Reliability of Lead-Free Solders

Author(s)
C A. Handwerker, D Noctor, G Whitten
In the assessment of the performance of lead-free solders, the most important question is how well these materials perform under conditions of thermomechanical...

Thin Film Confinement Effects on the Thermal Properties of Model Photoresist Polymers

Author(s)
Christopher L. Soles, Eric K. Lin, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Ronald L. Jones, Wen-Li Wu, D L. Goldfarb, M Angelopoulos
The demand to print increasingly smaller microelectronic device features means that the thickness of the polymer films used in the lithographic processes must...

The 1.27 m O2 Continuum Absorption in O2/CO2 Mixtures

Author(s)
Gerald T. Fraser, Walter J. Lafferty
The collision-induced, near-infrared O 2 continuum band overlapping the weak α 1δg - X 3ς- g, v=O -0, 1.27 m discrete band of O 2 has been investigated in O 2...

Molecular Iodine Clock

Author(s)
Jun Ye, L -. Ma, J L. Hall
We demonstrate a simple optical clock based on an optical transition of iodine molecules, providing a frequency stability stability superior to most rf sources...

Coherent Raman and Infrared Studies of Sulfur Trioxide

Author(s)
E T. Chrysostom, N Vulpanovici, Tony Masiello, J Barber, J W. Niblez, A Weber, A G. Maki, Thomas A. Blake
High resolution (0.001 cm -1) coherent anti-Stokes Raman scattering (CARS) was used to observe the Q-branch structure of the IR-inactive Ņ 1 symmetric...
