2.5 D Cavity Balancing
(200201)Cavity balancing is the process of altering the flow front within a cavity through thickness and design changes such that the desired fill pattern is achieved. The 2 dimensional (2D) cavitybalancing algorithm, developed ... 
Abnormality Detection in Retinal Images
(200401)The implementation of data mining techniques in the medical area has generated great interest because of its potential for more efficient, economic and robust performance when compared to physicians. In this paper, we focus ... 
Acceleration of Gas BubbleFree Surface Interaction Computation Using Basis Preconditioners
(200201)The computation of gas bubblefree surface interaction entails a timestepping algorithm whereby a linear system is solved at each timeiteration. In our investigation, the linear systems are derived from a desingularized ... 
AcceptabilityOriented Computing
(200401)We discuss a new approach to the construction of software systems. Instead of attempting to build a system that is as free of errors as possible, the designer instead identifies key properties that the execution must satisfy ... 
Accuracy Analysis and Improvement for Direct Laser Sintering
(200401)The accuracy issue of a rapid prototypingdirect laser sintering system is studied in this paper. The sources of errors are analyzed for their contribution to the final accuracy of built parts. The error sources are related ... 
Activation Ratios For Reconstruction Of Signal Transduction Networks
(200301)We have developed a novel framework that can be applied for the analysis of signal transduction networks, both to facilitate reconstruction of the network structure and quantitatively characterize the interaction between ... 
Active Hypothermic Growth: A Novel Means For Increasing Total Interferonγ Production by Chinese Hamster Ovary Cells
(200601)When grown under hypothermic conditions, Chinese Hamster Ovary (CHO) cells become growth arrested in the G₀/G₁ phase of the cell cycle and also often exhibit increased recombinant protein production. In this study, we ... 
Activity Recognition from Physiological Data using Conditional Random Fields
(200601)We describe the application of conditional random fields (CRF) to physiological data modeling for the application of activity recognition. We use the data provided by the Physiological Data Modeling Contest (PDMC), a ... 
Adhoc Collaborative Document Annotation on a Tablet PC
(200401)The use of technology as an effective educational tool has been an elusive goal in the past. Specifically, previous attempts at using small personal computers in the classroom to aid students as collaborative and notetaking ... 
Adaptive CacheOblivious AlltoAll Operation
(200401)Modern processors rely on cache memories to reduce the latency of data accesses. Extensive cache misses would thus compromise the usefulness of the scheme. Cacheaware algorithms make use of the knowledge about the cache, ... 
Adaptive Distributed Resource Allocation in Wireless Sensor Networks
(200601)Wireless sensor networks have emerged as a promising technology for a wide range of important applications. A major research challenge in this field is the distributed resource allocation problem, which concerns how the ... 
Adaptively Parallel Processor Allocation for Cilk Jobs
(200401)The problem of allocating processor resources fairly and efficiently to parallel jobs has been studied extensively in the past. Most of this work, however, assumes that the instantaneous parallelism of the jobs is known ... 
Addressing the Challenges of Aggregational and Temporal Ontological Heterogeneity
(200601)In this paper, we first identify semantic heterogeneities that, when not resolved, often cause serious data quality problems. We discuss the especially challenging problems of temporal and aggregational ontological ... 
Adversarial Analyses of Window Backoff Strategies for Simple MultipleAccess Channels
(200401)Backoff strategies have typically been analyzed by making statistical assumptions on the distribution of problem inputs. Although these analyses have provided valuable insights into the efficacy of various backoff strategies, ... 
Aerodynamic Shape Design of Nozzles Using a Hybrid Optimization Method
(200401)A hybrid design optimization method combining the stochastic method based on simultaneous perturbation stochastic approximation (SPSA) and the deterministic method of BroydonFletcherGoldfarbShanno (BFGS) is developed ... 
Aerodynamic Shape Design of Transonic Airfoils Using Hybrid Optimization Techniques and CFD
(200301)This paper will analyze the effects of using hybrid optimization methods for optimizing objective functions that are determined by computational fluid dynamics solvers for compressible viscous flow for optimal design of ... 
Aggregation of Synthetic Gene Delivery Vectors Enhance the Cellular Association and Uptake for in vitro Transfection
(200701)Development of safe and efficient synthetic gene delivery vectors is hampered with limited understanding the fundamental correlation of physicochemical properties of the vectors with their biological activities. Five major ... 
An Algorithm for Computing the Symmetry Point of a Polytope
(200401)Given a closed convex set C and a point x in C, let sym(x,C) denote the symmetry value of x in C, which essentially measures how symmetric C is about the point x. Denote by sym(C) the largest value of sym(x,C) among all x ... 
ALiCE: A Javabased Grid Computing System
(200301)A computational grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to highend computational capabilities. This talk is divided into three parts. Firstly, ... 
All learning is local: Multiagent learning in global reward games
(200401)In large multiagent games, partial observability, coordination, and credit assignment persistently plague attempts to design good learning algorithms. We provide a simple and efficient algorithm that in part uses a linear ...
