Author(s)
Emil Simiu, J P. Pinelli, C Subramanian, L. Zhang, A Cope, K Gurley, James J. Filliben, S Hamid
This paper reports progress in the development of a practical probabilistic model for the estimation of expected annual damage induced by hurricane winds in residential structures. The estimation of the damage is accomplished in several steps. First, basic

Author(s)
Paul E. Stutzman
Microscopy of portland cement clinker and cementitous materials dates to the first petrographic microscope in the late 19th century. The development of the scanning electron microscope (SEM) with x-ray microanalysis allows the petrographer to study cements

Virtual Permeametry on Microtomographic Images

November 1, 2004
Author(s)
C H. Arns, M A. Knackstedt, W V. Pinczewski, Nicos Martys
We show that accurate numerical micropermeametry measurements can be performed on three dimensional digitized images of sedimentary rock. The sample size can be very small making it possible to predict properties from core material not suited for
