171. 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 ...

172. Pose of I-Beams for Construction Site Automation
Topic: Math
Published: 9/21/2004
Authors: David E. Gilsinn, Geraldine S Cheok, Alan M. (Alan M.) Lytle
Abstract: Automation of construction processes can result in reduced project costs and increased worker safety. A process that lends itself to automation is the picking and placing of objects. However, determining the pose (position and orientation) of an ob ...

173. 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 ...

174. Precession Axis Modification to a Semi-analytical Landau-Lifshitz Solution Technique
Topic: Math
Published: 2/25/2008
Authors: Donald G Porter, Michael J Donahue
Abstract: A recent article [1] presents a semianalytical method to solve the Landau Lifshitz (LL) equation. Spin motion is computed analytically as precession about the effective field H, where H is assumed fixed over the time step. However, the exchange field ...

175. Predicted Functions of MdmX in Fine Tuning the Response of p53 to DNA Damage
Topic: Math
Published: 2/5/2010
Authors: Sohyoung Kim, Mirit I Aladjem, Geoffrey B McFadden, Kurt W Kohn
Abstract: Tumor suppressor protein p53 is negatively regulated by two structurally homologous proteins, Mdm2 and MdmX. In contrast to Mdm2, MdmX lacks ubiquitin ligase activity. Although the essential interactions of MdmX are known, it is not clear how they fu ...

176. Pseudo-Exhaustive Testing for Software
Topic: Math
Published: 4/28/2006
Authors: David R Kuhn, Vadim Okun
Abstract: Pseudo-exhaustive testing uses the empirical observation that, for broad classes of software, a fault is likely triggered by only a few variables interacting. The method takes advantage of two relatively recent advances in software engineering: algor ...

177. Quadratic Fermionic Interactions Yield Hamiltonians with Large Ground-state Energy Gaps
Topic: Math
Published: 3/24/2009
Authors: Dianne M O'Leary, Michael J. O'Hara
Abstract: Polynomially-large ground-state energy gaps are rare in many-body quantum systems, but required for adiabatic quantum computing. We show analytically that the gap is generically polynomially-large for quadratic fermionic Hamiltonians, first conside ...

178. Quantum Simulations of Classical Annealing Processes
Topic: Math
Published: 9/26/2008
Authors: Rolando Somma, S. Boixo, Howard Barnum, Emanuel H Knill
Abstract: We describe a quantum algorithm that solves combinatorial optimization problems by quantum simulation of a classical simulated annealing process. Our algorithm exploits quantum walks and the quantum Zeno effect induced by evolution randomization. It ...

179. Random-Effects Model for Meta-analysis of Clinical Trials: An Update
Topic: Math
Published: 1/1/2007
Authors: Rebecca DerSimonian, Raghu N Kacker
Abstract: The random-effects model is a useful approach for meta-analysis of clinical studies. It explicitly accounts for the heterogeneity of studies through a statistical parameter representing the inter-study variation. We discuss several iterative and non- ...

180. Randomized methods for rank-deficient linear systems
Topic: Math
Published: 2/13/2015
Authors: Josef Sifuentes, Zydrunas Gimbutas, Leslie Greengard
Abstract: We present a simple, accurate method for solving consistent, rank-deficient linear systems, with or without additional rank-completing constraints. Such problems arise in a variety of applications, such as the computation of the eigenvectors of a ma ...
