Modified Slump Test to Measure Rheological Parameters of Fresh Concrete

December 1, 1998
Author(s)
Chiara F. Ferraris, F DeLarrard
The ease of placement of concrete depends upon at least two physical properties, the yield stress and plastic viscosity. Currently the most common field test is the slump test, and it is related only to the yield stress. Therefore, a simple field test

Numerical Simulation of Atomization Gas Flows

December 1, 1998
Author(s)
Pedro I. Espina, Stephen D. Ridder, U Piomelli, Frank S. Biancaniello
The gas-only flow in a close-coupled, gas-metal atomizer is Studied to determine the influence of operational parameters on The structure of the flow field. A parametric study is conducted to determine the effects of jet exit pressure ratio, jet

Parallel Algorithms for Entropy-Coding Techniques

December 1, 1998
Author(s)
Abdou S. Youssef
With the explosion of imaging applications, and due to the massive amounts of imagery data, data compression is essential. Lossless compression also called entropy coding, is of special importance because not only it serves as a stand-alone system for

Ralaxometry and Magnetometry of Ferritin

December 1, 1998
Author(s)
R A. Brooks, J Vymazal, Ronald B. Goldfarb, J W. Bulte, P Aisen
By combining nuclear magnetic ralaxometry on 39 ferritin samples with different iron loading with magnetometry, results were obtained that suggest a new interpretation of the core structure and magnetic properties of ferritin. These studies provide
