A Ball and Beam Module for a Haptic Paddle Education Platform
(2017)Single degree of freedom forcefeedback mechatronic devices, often called haptic paddles, are used in university curriculum as well as massive open online courses (MOOCs). While devices differ based on the goals of a given ... 
A Bayesian Integrative Model for Genetical Genomics with Spatially Informed Variable Selection
(2014)We consider a Bayesian hierarchical model for the integration of gene expression levels with comparative genomic hybridization (CGH) array measurements collected on the same subjects. The approach defines a measurement ... 
A behavioral approach to positive interpolation
(2005)We study interpolation by positive functions from a behavioural point of view. In particular, by considering the notion of mirror image data, the interpolation problem with passivity constraint is transformed into an ... 
A Block Coordinate Descent Method for MultiConvex Optimization with Applications to Nonnegative Tensor Factorization and Completion
(201208)This paper considers block multiconvex optimization, where the feasible set and objective function are generally nonconvex but convex in each block of variables. We review some of its interesting examples and propose a ... 
A Branch and Cut Algorithm for Nonconvex Quadratically Constrained Quadratic Programming
(199901)We present a branch and cut algorithm that yields in finite time, a globally epsilonoptimal solution (with respect to feasibility and optimality) of the nonconvex quadratically constrained quadratic programming problem. ... 
A Branch Decomposition Algorithm for the pMedian Problem
(2017)In this paper, we use a branch decomposition technique to improve approximations to the pmedian problem. Starting from a support graph produced either by a combination of heuristics or by linear programming, we use dynamic ... 
A C++ Class Supporting AdjointState Methods
(200909)The adjointstate method is widely used for computing gradients in simulation driven optimization problems. The adjointstate evolution equation requires access to the entire history of the system states. There are ... 
A cablebased series elastic actuator with conduit sensor for wearable exoskeletons
(2017)There is currently a scarcity of wearable robotic devices that can practically provide physical assistance in a range of real world activities. Soft wearable exoskeletons, or exosuits, have the potential to be more portable ... 
A CharacteristicMixed Method for Contaminant Transport and Miscible Displacement
(199202)Recently, Arbogast and Wheeler have formulated and analyzed a modified method of characteristicsmixed method for approximating solutions to convectiondiffusion equations. This scheme is theoretically mass conservative ... 
A CharacteristicsMixed Finite Element Method for Advection Dominated Transport Problems
(199211)We define a new finite element method, called the characteristicsmixed method, for approximating the solution to an advection dominated transport problem. The method is based on a spacetime variational form of the ... 
A Characterization of Compound Documents on the Web
(19991129)Recent developments in office productivity suites make it easier for users to publish rich {\em compound documents\/} on the Web. Compound documents appear as a single unit of information but may contain data generated by ... 
A Chemical Compositional Reservoir Simulator on Distributed Memory Parallel Computers: Comparative ParallelUTCHEM Simulation Performance Study (Part I)
(199411)This paper presents the application of distributed memory parallel computers to field scale reservoir simulations using a parallel version of UTCHEM, The University of Texas Chemical Flooding Simulator. The model is a ... 
A ClosedForm Technique for the Reliability and Risk Assessment of Wind Turbine Systems
(2012)This paper proposes a closedform method to evaluate wind turbine system reliability and associated failure consequences. Monte Carlo simulation, a widely used approach for system reliability assessment, usually requires ... 
A closedloop model of the ovine cardiovascular system
(2003)The conscious sheep is an important large animal model for the study of human cardiovascular and cardiopulmonary system. In this study we develop a closedloop mathematical model of its cardiovascular system. A distributed ... 
A Closer Look at Drawbacks of Minimizing Weighted Sums of Objectives for Pareto Set Generation in Multicriteria Optimization Problems
(199612)A standard technique for generating the Pareto set in multicriteria optimization problems is to minimize (convex) weighted sums of the different objectives for various different settings of the weights. However, it is ... 
A coding theoretic approach to image segmentation
(2001)Using a coding theoretic approach, we achieve unsupervised image segmentation by implementing Rissanen's concept of Minimum Description Length (MDL) for estimating piecewise homogeneous regions in images. MDL offers a ... 
A Combinatorial Abstraction of One Shortest Path Problem and Its Relationship to Greedoids
(198805)A natural generalization of the shortest path problem to arbitrary set systems is presented that captures a number of interesting problems, including the usual graphtheoretic shortest path problem and the problem of finding ... 
A Combined ShapeNewton and Topology Optimization Technique in RealTime Image Segmentation
(200407)In this paper, for solving a class of shape optimization problems, a new algorithmic concept combining shape and topological sensitivities is presented. The geometry of interest is represented by means of geometrical ... 
A common tattoo chemical for energy storage: henna plantderived naphthoquinone dimer as a green and sustainable cathode material for Liion batteries
(2018)The burgeoning energy demands of an increasingly ecoconscious population have spurred the need for sustainable energy storage devices, and have called into question the viability of the popular lithium ion battery. A ... 
A communications and interaction model for intelligent cooperating robots
(1993)In complex robotic operating environments in which robots must cooperate in a flexible and eventdriven manner, a cooperative distributed environment for intelligent control is required. We develop a realistic technique ...
