51. Dielectric Breakdown in a Simplified Parallel Model
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6174
Topic: Modeling
Published: 6/1/1998
Authors: H A Fowler, J E Devaney, John G Hagedorn, F Sullivan

52. Discrete Fourier Series Approximation to Periodic Solutions of Autonomous Delay Differential Equations
Topic: Modeling
Published: 1/2/2006
Author: David E. Gilsinn
Abstract: We begin this expository essay by reviewing with examples what a typical engineer already knows about statistics. We then consider a central question in engineering decision making, i.e., given a computer simulation of high-consequence systems, how ...

53. Distributed Deployment Algorithms for Improved Coverage in a Network of Wireless Mobile Sensors
Topic: Modeling
Published: 2/1/2014
Authors: Kamran Sayrafian, Vladimir V Marbukh, Hamid Mahboubi, Kaveh Moezzi, Amir Aghdam
Abstract: In this paper, sensor deployment strategies are developed for effective coverage in wireless sensor networks. In the proposed algorithms, the sensors find coverage holes within the corresponding Voronoi polygons, and then move in a proper directi ...

54. Eigenfunction expansions for a fundamental solution of Laplace's equation on R^u3^ in parabolic and elliptic cylinder coordinates
Topic: Modeling
Published: 8/14/2012
Authors: Howard S Cohl, Hans Volkmer
Abstract: A fundamental solution of Laplace's equation in three dimensions is expanded in harmonic functions that are separated in parabolic or elliptic cylinder coordinates. There are two expansions in each case which reduce to expansions of the Bessel funct ...

55. Elucidating the Effects of Adsorbent Flexibility on Fluid Adsorption Using Simple Models and Flat-Histogram Sampling Methods
Topic: Modeling
Published: 6/24/2014
Authors: Vincent K Shen, Daniel W Siderius
Abstract: Using flat-histogram Monte Carlo methods, we investigate the adsorptive behavior of the square-well fluid in two simple slit-pore- like models intended to capture fundamental characteristics of flexible adsorbent materials. The models require thermo ...

56. Erratum: "Developments in determining the gravitational potential using toroidal functions"
Topic: Modeling
Published: 10/2/2012
Author: Howard S Cohl
Abstract: We fix several errors in "Developments in determining the gravitational potential using toroidal functions" (Astronomische Nachrichten, Vol. 321, Issue 5/6, p. 363).

57. 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 ...

58. Estimating Volumes of Near-spherical Molded Artifacts
Series: Journal of Research (NIST JRES)
Topic: Modeling
Published: 5/3/2010
Authors: David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
Abstract: The Food and Drug Administration (FDA) is conducting research on developing reference lung cancer cancer lesions, called phantoms, to test computed tomography (CT) scanners and their software. FDA loaned two semi-spherical phantoms to the National In ...

59. Estimating Volumes of Simulated Lung Cancer Nodules
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7571
Topic: Modeling
Published: 7/15/2009
Authors: David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
Abstract: Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. Computed tomography (CT) shows promise in detecting lung cancers at earlier, more operable stages, when survival is better. CT scans generate multiple 2-D slice images of th ...

60. Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth
Topic: Modeling
Published: 6/29/2012
Authors: Afzal A Godil, Helin Dutagaci
Abstract: In this paper, we present an evaluation strategy based on human-generated ground truth to measure the performance of 3D interest point detection techniques. We provide quantitative evaluation measures that relate automatically detected interest point ...
