32. Recommendation for Password-Based Key Derivation Part I: Storage Applications
Series: Special Publication (NIST SP)
Report Number: 800-132
Topic: Math
Published: 12/22/2010

33. Biological Cell Feature Identification by a Modified Watershed-Merging Algorithm
Series: NIST Interagency/Internal Report (NISTIR)
Topic: Math
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 ...

34. Bicubic B-Spline Surface Approximation of Invariant Tori
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7731
Topic: Math
Published: 10/20/2010
Authors: Sita Ramamurti, David E. Gilsinn
Abstract: The invariant torus of a coupled system of Van der Pol oscillators is approximated using bicubic B-splines. The paper considers the case of strong nonlinear coupling. In particular, the shapes of invariant torii for the Van der Pol coupling parameter ...

35. A New Analysis of the False-Positive Rate of a Bloom Filter
Topic: Math
Published: 10/15/2010
Authors: Ken Christensen, Allen L Roginsky, Miguel Jimeno
Abstract: A Bloom filter is a space-efficient data structure used for probabilistic set membership testing. When testing an object for set membership, a Bloom filter may give a false positive. The analysis of the false positive rate is key to understanding the ...

36. Modelling Type Ia Supernova Light Curves
Topic: Math
Published: 9/15/2010
Authors: Bert W Rust, Dianne M O'Leary, Katharine M Mullen
Abstract: Type Ia supernova light curves are characterized by a rapid rise from zero luminosity to a peak value, followed by a slower quasi-exponential decline. The rise and peak last for a few days, while the decline persists for many months. It is widely b ...

37. Practical Near-Collisions for Reduced Round Blake, Fugue, Hamsi and JH
Topic: Math
Published: 8/23/2010
Authors: Meltem Sonmez Turan, Erdener Uyan
Abstract: A hash function is near-collision resistant, if it is hard to find two messages with hash values that differ in only small number of bits. In this study, we used hill climbing methods to find near-collisions for some of the second round SHA-3 candida ...

38. Performance Measurements for Evaluating Static and Dynamic Multiple Human Detection and Tracking Systems in Unstructured Environments
Topic: Math
Published: 6/30/2010
Authors: Bodt Bodt, Richard Camden, Harry A. Scott, Adam S Jacoff, Tsai Hong Hong, Tommy Chang, Richard J Norcross, Anthony J Downs, Ann M Virts
Abstract: The Army Research Laboratory (ARL) Robotics Collaborative Technology Alliance (CTA) conducted an assessment and evaluation of multiple algorithms for real-time detection of pedestrians in Laser Detection and Ranging (LADAR) and video sensor data take ...

39. Onset of Convection in Binary Liquid Layers
Topic: Math
Published: 3/24/2010
Authors: Geoffrey B McFadden, Sam Ray Coriell, Aaron Lott
Abstract: We perform linear stability calculations for horizontal bilayers of a two-component fluid that can undergo a phase transformation, taking into account both buoyancy effects and thermocapillary effects in the presence of a vertical temperature gradien ...

40. The Solidification of an Ideal Ternary Alloy in a Mushy Layer
Topic: Math
Published: 3/24/2010
Authors: Daniel M Anderson, Geoffrey B McFadden, Sam Ray Coriell, Bruce Murray
Abstract: We consider a model for the solidification of an ideal ternary alloy in a mushy layer that incorporates the effects thermal and solutal diffusion, convection and solidification. Our results reveal that although the temperature and solute fields are ...
