121. Deconvolving LADAR Images Of Bar Codes for Construction Site Object Recognition
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7044
Topic: Modeling
Published: 10/1/2003
Authors: David E. Gilsinn, Geraldine S Cheok, Dianne M O'Leary
Abstract: This report discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADAR optics. The first part of this report describes the experimental data collection of several bar code images along ...

122. An Optimization Approach to Multiple Sequence Alignment
Topic: Modeling
Published: 7/1/2003
Authors: Fern Y Hunt, Anthony J Kearsley, H H Wan
Abstract: The problem of multiple sequence alignment is recast as an optimization problem using Markov decision theory. One seeks to minimize the expected or average cost of alignment subject to data-derived constraints. In this setting the problem is equiva ...

124. Reconstructing Images of Bar Codes for Construction Site Object Recognition
Topic: Modeling
Published: 9/1/2002
Authors: David E. Gilsinn, Geraldine S Cheok, Dianne M O'Leary
Abstract: This paper discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADARoptics. The first part of this paper describes the experimental data collection of several bar code images along w ...

125. Comparative Statistical Analysis of Test Parts Manufactured in Production Environments
Report Number: 6868
Topic: Modeling
Published: 6/1/2002
Authors: David E. Gilsinn, Alice V. Ling
Abstract: Estimating error uncertainties arising in parts produced on machine tools in production machine shops is not a well understood process. The current study details a process of estimating these error uncertainties. A part with significant features was ...

126. Estimating Critical Hopf Bifurcation Parameters for a Second Order DelayDifferential Equation with Application to Machine Tool Chatter
Topic: Modeling
Published: 5/1/2002
Author: David E. Gilsinn
Abstract: Nonlinear time delay differential equations are well known to have arisen in models in physiology, biology and population dynamics. They have also arisen in models of metal cutting processes. Machine tool chatter, from a process called regenerative c ...

127. Constructing Sibson Elements for a Rectangular Mesh
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6718
Topic: Modeling
Published: 2/1/2001
Author: David E. Gilsinn
Abstract: This paper documents the construction of a finite element, called the Sibson element. The shape function of this element is formed on rectangular grids by C^u1^ splines defined on a triangulation of each subrectangle by dividing it into four subtri ...

128. Multiresolution Representation of Urban Terrain By L^1^ Splines, L^2^ Splines, and Piecewise Planar Surfaces
Topic: Modeling
Published: 12/11/2000
Authors: J E Lavery, David E. Gilsinn
Abstract: Cubic L^d1^ and L^d2^ interpolating splines based on C^u1^ smooth piecewise cubic Sibson elements on a tensor-product grid are investigated. Computational tests were carried out for a 102.4 km area of Fort Hood, Texas represented by a 1025 x 1025 set ...
