[20060310] Applications of Quantifier Elimination Theory to Control Theory
In this paper we show how a number of interesting linear control system analysis and design problems can be reduced to Quantifier Elimination (QE) problems. We assume a fixed structure for the compensator, with design ... 
[20110322] A Categorical Model for Faceted Ontologies with Data Repositories
We present a theoretical framework for faceted ontologies equipped with data repositiories. The ontology structures, inferencing within ontologies, and repository use and updating are expressed using mathematical structures ... 
[20101026] A Comparison of a Curve Fitting Tracking Filter and Conventional Filters under Intermittent Information
This technical report accompanies the tracking filter based on geometric properties of targets' maneuvers developed in our submission for the Journal of Autonomous Robots. Herein, we compare estimation quality, processing ... 
[20141211] Comparison on Different Discrete Fractional Fourier Transform (DFRFT) Approaches
As an extension of the conventional Fourier transform and as a timefrequency signal analysis tool, the fractional Fourier transforms (FRFT) are suitable for dealing with various types of nonstationary signals. Taking ... 
[20060310] Design and Analysis of the Alliance / University of New Mexico Roadrunner Linux SMP SuperCluster
This paper will discuss high performance clustering from a series of critical topics: architectural design, system software infrastructure, and programming environment. This will be accomplished through an overview of ... 
[20080826] A Dynamic Programming Approach for Routing in Wireless Mesh Networks
The routing problem in Wireless Mesh Networks (WMNs) is concerned with finding “good” source destination paths. It generally faces multiple objectives to be optimized, such as i) path capacity, which accounts for the bits ... 
[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 ...
