[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 ... 
[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 ... 
[20060310] Non Stationary Signal Analysis, Energy Demodulation and the Multicomponent AMFM Signal Model
This report addresses the problem of nonstationary signal analysis and multicomponent AM–FM signal separation and demodulation, which are important and significant problems in the area of non stationary signal modeling. ... 
[20110510] Nonnegative Quadratic Programming Total Variation Regularization for Poisson VectorValued Image Restoration
We propose a flexible and computationally efficient method to solve the nonhomogeneous Poisson (NHP) model for grayscale and color images within the TV framework. The NHP model is relevant to image restoration in ... 
[20070417] On Discrete GaussHermite Functions and Eigenvectors of the Discrete Fourier Transform
The problem of furnishing an orthogonal basis of eigenvectors for the discrete Fourier transform (DFT) is fundamental to signal processing. Recent developments in the area of discrete fractional Fourier analysis also ... 
[20110801] On Orthogonal Modes of Continuous and Discrete Frequency Modulation
Fourier analysis techniques remain the staple tools for the processing of sinusoidal signals with stationary frequency content. These techniques however, are unsuitable for the analysis of signals with timevarying ... 
[20060310] On the Computational Complexity of the Manufacturing Job Shop and Renetrant Flow Line
This paper presents a comparison study of the computational complexity of the general job shop protocol and the flow line protocol in a flexible manufacturing system. It is shown that a certain representative problem ... 
[20101013] On the Configuration of Sensors and Actuators on a Pioneer 3AT Robot Controlled through the Robotic Operating System ROS
We present a set of technical procedures to carry out experiments involving mobile robots. The hardware and software configuration to access the sensors and actuators in the robots usually turn out to be a relatively ... 
[20060310] On the Grunbaum Commutor Based Discrete Fractional Fourier Transform
The basis functions of the continuous fractional Fourier transform (FRFT) are linear chirp signals that are suitable for timefrequency analysis of signals with chirping timefrequency content. In the continuoustime ... 
[20060310] Output Stabilizability
In this report, we provide algebraic tests to determine whether a linear Single InputSingleOutput (SISO) system, is stabilizable with a constant output feedback. 
[20060310] PhaseConvex Arcs in Root Space and Their Application to Robust SPR Problem
This paper considers the problem of identifying regions in the complexplane, such that polynomials having roots in those regions, have their phase bounded by that of a few extreme polynomials. We present sufficient and ... 
[20060310] A Practical Parallel Algorithm for Cycle Detection in Partitioned Digraphs
Graph theoretic techniques are used in variety of important computational problems in the areas of computational physics, mechanics, and fluid flow. We present a new, parallel algorithm for detecting cycles in ... 
[20110919] Pre Incident Indicator Analysis (PIIA) System
Policy leaders have identified a need for a mathematical based computational system that would support requirements of situational awareness to analyze terrorist threats and risks given the vast amount of input data in the ...

Collaborative Virtual Environments (CVEs) are distributed virtual reality systems that allow multiple geographically distant users to communicate with each other and interact with virtual objects in a shared virtual ... 
[20110311] Radiobots: Architecture, Algorithms and Realtime Reconfigurable Antenna Designs for Autonomous, Selflearning Future Cognitive Radios
In current literature, the definition of a cognitive radio (CR) seems to be different from one research community to another: For communication theorists it is about dynamic spectrum sharing (DSS), for hardware/RF ... 
[20060310] A Randomized Parallel Sorting Algorithm With an Experimental Study
Previous schemes for sorting on generalpurpose parallel machines have had to choose between poor load balancing and irregular communication or multiple rounds of alltoall personalized communication. In this paper, ...
