[20070509] Efficient User Controlled InterDomain SIP Mobility: Authentication, Registration, and Call Routing
Over the past decade, multimedia services have gained significant acceptance and played an important role in the convergence of IP networks. Supporting mobility in IP (Internet Protocol) networks is a crucial step towards ... 
[20100927] An Emotion Model for Video Game AI
Modeling human behavior in computer simulations and games is a subject which draws considerable attention. Despite the increased realism of graphics in games, poor modeling of nonplayer characters’ AI often leads to a ... 
[20060310] An Experimental Comparison of Parallel Algorithms for Ear Decomposition of Graphs using Two Leading Paradigms
Graph decomposition is an important and necessary operation when solving graphtheoretic problems on parallel computers, for instance, from computational fluid dynamics, mechanics, and astrophysics. In this paper, we design ... 
[20060310] High Performance Computing Applications in Remote Sensing Studies for Land Cover Dynamics
Global and regional land cover studies require the ability to apply complex models on selected subsets of large amounts of multisensor and multitemporal data sets that have been derived from raw instrument measurements using ... 
[20110912] Implementation of Random Parameter Filtering
Monte Carlo (MC) rendering systems can produce spectacular images but are plagued with noise at low sampling rates. In a recent paper, we observed that this noise occurs in regions of the image where the sample values are ... 
[20060310] An Improved Randomized Selection Algorithm With an Experimental Study
A common statistical problem is that of finding the median element in a set of data. This paper presents an efficient randomized highlevel parallel algorithms for finding the median given a set of elements distributed ... 
[20080308] Interconnected Hybrid Systems: A Framework for Multiagent Systems with Hybrid Interacting Dynamics
We present a new framework for describing multiagent systems with hybrid interacting dynamics where the interaction between agents occurs at both the continuous and discrete levels. We formally define these multiagent ... 
[20070507] The InterMesh Network Architecture
The rapid spread of mobile devices, the emergence of key wireless technologies, and the nomadic user and computing lifestyles on current networks are continuously evolving in synergy. MANETs, WSNs, and WMNs are examples ... 
[20060310] Kronos: A JavaBased Software System for the Processing and Retrieval of Large Scale AVHRR Data
At regional scales, satellitebased sensors are the primary source of information to study the earth’s environment, as they provide the needed dynamic temporal view of the earth’s surface. Raw satellite orbit data have ... 
[20070417] LeaderFollower Control with Odometry Error Analysis
In this paper we present a leaderfollower control law that enables a mobile robot to track a desired trajectory, and allows us to specify the position in the plane of the follower robot with respect to the leader robot. ... 
[20080701] A Model of Human Categorization and Similarity Based Upon Category Theory
Categorization and the judgement of similarity are fundamental in cognition. We propose that these and other activities are based upon an underlying structure of knowledge, or concept representation, in the brain. Further, ... 
[20060310] Neural Networks, Knowledge and Cognition: A Mathematical Semantic Model Based upon Category Theory
Category theory can be applied to mathematically model the semantics of cognitive neural systems. We discuss semantics as a hierarchy of concepts, or symbolic descriptions of items sensed and represented in the connection ... 
[20160324] The Neural Representation of Concepts at the Sensor Level
This report presents a mathematical model of the semantics, or meaning, of the connec tionist structure and stimulus activity of a neural network, whether artificial or biologi cal. The mathematical model associates ... 
[20141114] New Approaches to High Power Microwave Computation and Experimentation
This final technical report describes the conclusion of effort on the New World Vistas grant entitled "New Approaches to High Power Microwave Computation and Experimentation.' In the final year of effort we focused on ... 
[20060310] A New Deterministic Parallel Sorting Algorithm With an Experimental Evaluation
We introduce a new deterministic parallel sorting algorithm for distributed memory machines based on the regular sampling approach. The algorithm uses only two rounds of regular alltoall personalized communication in a ... 
[20060310] A New Implementation and Detailed Study of Breakpoint Analysis
Phylogenies derived from gene order data may prove crucial in answering some fundamental open questions in biomolecular evolution. Yet very few techniques are available for such phylogenetic reconstructions. One method ...
