[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 ... 
[20060310] A Prototype System for Collaborative Virtual Environments: Design and Characterization
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, ... 
[20070417] Resource Allocation for Multiagent Problems in the Design of Future Communication Networks
A new architecture for a smarter Internet abstracts the functional components of the network from the hardware that enables it. This is done via software agents that implement such functions and are capable of relocating ... 
[20110912] A Simple Ontology for the Analysis of Terrorist Attacks
The need for shared understanding in the analysis of terrorist activity has been a clearly defined national priority for over a decade. We present a foundation for an ontology to represent adversary groups and their ... 
[20060310] SIMPLE: A Methodology for Programming High Performance Algorithms on Clusters of Symmetric Multiprocessors (SMPs) (Preliminary Version)
We describe a methodology for developing high performance programs running on clusters of SMP nodes. The SMP cluster programming methodology is based on a small prototype kernel (SIMPLE) of collective communication primitives ... 
[20060310] Speckle noise modeling and reduction of SAR Images based Markov random fields
One of the major factors plaguing the performance of synthetic aperture radar (SAR) imagery is the signaldependent, speckle noise. Grainy in appearance, it is due to the phase fluctuations of the electromagnetic returned ... 
[20060310] Speckle Reduction of SAR Images Based on a Combined Markov Random Field and Statistical Optics Approach (Version1)
One of the major factors plaguing the performance of synthetic aperture radar (SAR) imagery is the presence of signaldependent, speckle noise. Grainy in appearance, speckle noise is primarily due to the phase fluctuations ...
