[20100209] RF channel characterization for cognitive radio using support vector machines
Cognitive Radio promises to revolutionize the ways in which a user interfaces with a communications device. In addition to connecting a user with the rest of the world, a Cognitive Radio will know how the user wants to ... 
[20110208] Rheological and nanomechanical characterization of aging in polymer modified asphalt
In this study, change in rheological and nanomechanical properties of asphalt due to aging is determined in the laboratory. Asphalt binders are aged using Rolling Thin Film Oven (RTFO), Pressure Aging Vessel (PAV), and ... 
[20100909] Rights management over web mashups
Web mashups have become one of the most powerful features of the Web 2.0 revolution. Though the sources of the mashups have access control over their content, the lack of proper Rights Management over the content given out ... 
[20120424] Robust adaptive control for a class of partially known nonlinear systems
An adaptive controller is developed that takes advantage of the structure and any known dynamics of the system in order to increase speed of adaptation and relax the conditions required for convergence. The control design ... 
[20120424] Robust control of accelerators
The problem of controlling tile variations in the rf power system can be effectively cast as an application of modern control theory. Two components of this theory are obtaining a model and a feedback structure. The model ... 
[20120424] Robust Control of Particle Accelerators
Abstract In this paper, we present a new technique for controlling the electric fields of an electron particle accelerator. This new scheme has greater stability and performance robustness than was previously achieved. 
[20120412] Robust finitetime stability design via linear matrix inequalities
For linear systems with polytopic uncertainties, the problem of robust finitetime stabilization is reduced to a system of Linear Matric Inequalities. 
[20120413] Robust lateral control of highway vehicles
Vehicle lateral dynamics are affected by vehicle mass, longitudinal velocity, vehicle inertia, and the cornering stiffness of the tires. All of these parameters are subject to variation, even over the course of a single ... 
[20120329] Robust mobile robotic formation control using internetlike protocols
This work presents an internetlike protocol (ILP) to coordinate the formation of n secondorder agents in a two dimensional (2D) space. The trajectories are specified trough via points and a desired formation at each ... 
[20120412] Robust multiobjective feedback design via combined quantifier elimination and discretization
This paper deals with the application of computerized quantifier elimination (QE) methods for robust multiobjective feedback design, when design objectives are specified in the frequency domain. The class of design problems ...

[20130131] A robust patchbased synthesis framework for combining inconsistent images
Current methods for combining different images produce visible artifacts when the sources have very different textures and structures, come from far view points, or capture dynamic scenes with motions. In this thesis, ... 
[20120330] Robust stability of time delay systems: Theory
Given that a timedelay system is stable for some delay h0 > 0, a procedure is given to find the stability interval [h1 ; h2 ] such that h0 2 [h1 ; h2] and for all h satisfying h1 < h < h2 the system is stable. Further, ... 
[20120407] Robust, nonfragile and optimal controller design via linear matrix inequalities
In this article, we introduce a robust nonfragile state feedback controller which is also optimal with respect to a quadratic performance index, using linear matrix inequalities (LMI). The uncertainties are assumed to be ... 
[20120424] A Routhlike algorithm in system identification and adaptive control
This paper introduces algorithms to be used for finding the Cauchy index of a transfer function and for solving the Diophantine equation. The algorithms are similar to the RouthHurwitz array in structure and are simple ...
