Engineered porosity via tape casting, lamination and the percolation of pyrolyzable particulates
(American Ceramic Soc, 1999-07)
Sintered ceramic preforms with open pore volumes from 20% to 80% (with no alteration in sintering shrinkage) were developed by adding pyrolyzable pore-forming agents (PFAs) to a tape-casting colloidal suspension. Sintered ...
Local Nonlinear Filtering
(Springer-Verlag New York Inc, 1997)
Classical methods of filtering time series use Fourier power spectral analysis to separate signals from noise. Improved methods of signal separation can be developed by using projection techniques based on concepts of ...
KLT-Based quality controlled compression of single-lead ECG
An electrocardiogram (ECG) compression algorithm based on a combination of the Karhunen-Loeve transform (KLT) and multirate sampling is introduced. The use of multirate sampling reduces KLT computational times to those ...
Price probing in the simplex method
This paper describes remote probing, a method that employs the principle of external pivoting and evaluates points with respect to their objective values from a given basic point, i.e., without ever moving out of that basic ...
A Computational Study of Redundancy in Randomly Generated Polytopes
In this paper we first survey a number of principles used to randomly generate linear programming problems. Three major classes of LP generators are identified and on that basis five generators for further study are defined. ...

A spatial criterion as decision aid for capital projects: locating a sewage treatment plant in Halifax, Nova Scotia
This paper describes a decision tool based on a domain criterion originally designed for games against nature. We employ this technique to analyse the locational choice of a sewage treatment plant in the city of Halifax, ...
A computational investigation into shapes of polyhedra
In this paper we first derive a measure to evaluate the shape of polyhedra based on the well-known concept of roundness. The resulting roundness index expresses the degree of deformity of a polyhedron measured as the ...
The Lorenz-Krishnamurthy slow manifold
The authors scale the five-mode model introduced by Lorenz and Krishnamurthy and show how explicit solutions may be obtained in the limit of small Rossby number by using the method of multiple scales. They thus obtain a ...
Spatial variation in liquefaction risk
(Thomas Telford Services Ltd, 1998)
Basic concepts and methods of random field theory, useful for characterizing 'distributed disordered systems', are applied to a soil deposit to evaluate the spatial extent of liquefaction under typical conditions. The soil ...
