21. Biological Cell Feature Identification by a Modified Watershed-Merging Algorithm
Series: NIST Interagency/Internal Report (NISTIR)
Topic: Modeling
Published: 11/24/2010
Authors: David E. Gilsinn, Kiran Bhadriraju, John T Elliott
Abstract: Biological cells are composed of many subsystems and organelles. The subsystem called the cytoskeleton is composed of long rod-shaped structures. They give the cell form and help attach the cell to the substrate and neighbors. One of the filaments is ...

22. COMPARISON OF TWO DIMENSION-REDUCTION METHODS FOR NETWORK SIMULATION MODELS
Series: Journal of Research (NIST JRES)
Report Number: 116-5
Topic: Modeling
Published: 10/5/2011
Authors: Kevin L Mills, James J Filliben
Abstract: Experimenters characterize the behavior of simulation models for data communications networks by measuring multiple responses under selected parameter combinations. The resulting multivariate data may include redundant responses reflecting aspects of ...

23. Cell Morphology and Migration Linked to Substrate Rigidity
Topic: Modeling
Published: 1/1/2007
Authors: Yong Ni, Martin Y Chiang
Abstract: A mathematical model, based on thermodynamics, was developed to demonstrate the substrate mechanics influences the cell morphology and migration. The mechanisms by which substrate rigidity are translated into cell morphological changes and cell movem ...

24. Comment on "Frustrated Magnetization in Co Nanowires: Competition Between Crystal Anisotropy and Demagnetization Energy"
Topic: Modeling
Published: 9/15/2010
Authors: Kristof M. Lebecki, Michael J Donahue
Abstract: Bergmann et al. [Phys. Rev. B 77, 054414 (2008)] present an analytical theory explaining the behavior of ferromagnetic cobalt nanowires with perpendicular anisotropy. This theory, which predicts a sinusoidal variation of the magnetization along the l ...

25. 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 ...

26. Comparative Statistical Analysis of Test Parts Manufactured in Production Environments
Series: NIST Interagency/Internal Report (NISTIR)
Topic: Modeling
Published: 2/2/2004
Authors: David E. Gilsinn, Alice V. Ling
Abstract: Estimating error uncertainties arising in production parts isnot a well understood process. This study developed an approach to estimatethese uncertainties. Machine tool error components on a vertical turningcenter were measured. Multiple parts were ...

27. Comparing VM-Placement Algorithms for On-Demand Clouds
Topic: Modeling
Published: 11/29/2011
Authors: Kevin L Mills, James J Filliben, Christopher E Dabrowski
Abstract: Much recent research has been devoted to investigating algorithms for allocating virtual machines (VMs) to physical machines (PMs) in infrastructure clouds. Many such algorithms address distinct problems, such as initial placement, consolidation, or ...

28. Computable Error Bounds for Approximate Periodic Solutions of Autonomous Delay Differential Equations
Topic: Modeling
Published: 1/2/2007
Author: David E. Gilsinn
Abstract: In this paper we prove a result that says: Given an approximate solution and frequency to a periodic solution of an autonomous delay differential equation that satisfies a certain non-criticality condition, there is an exact periodic solution and fre ...

29. Constructing Sequence Alignments from a Markov Decision Model with Estimated Parameter Values
Topic: Modeling
Published: 1/1/2004
Authors: Fern Y Hunt, Anthony J Kearsley, Agnes (Abbie) O'Gallagher
Abstract: Current methods for aligning biological sequences are based on dynamic programming algorithms. If large numbers of sequences or a number of long ones are to be aligned the required computations are expensive in memory and CPU time. In an attempt to b ...
