[20120407] Robust nonfragile LQ controllers: the static state feedback case
This paper describes the synthesis of nonfragile or resilient regulators for linear systems. A general framework for fragility is described using statespace methodologies, and the LQ/H2 static statefeedback problem is ... 
[20120410] Robust nonfragile LQ controllers: the static state feedback case
This paper describes the synthesis of nonfragile or resilient regulators for linear systems. The general framework for fragility is described using statespace methodologies, and the LQ/H2 static statefeedback case is ... 
[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 ... 
[20130130] S band narrowwall slotted waveguide antenna For highpower applications
This work seeks designs of novel antennas, such as the rectangular waveguide narrowwall longitudinalaperture antenna arrays for S band high power applications. This antenna is designed to perform as a uniform array with ... 
[20120703] Seasonal influent characterization, model calibration, SRT and energy usage for nitrogen removal at a full scale wastewater plant
This study focused on factors affecting biological denitrification in wastewater treatment. Denitrification is a process in which heterotrophic bacteria use nitrate as an electron acceptor (in the absence of oxygen) and ... 
[20100909] Second law analysis of a natural gasfired steam boiler and cogeneration plant
A second law thermodynamic analysis of a natural gasfired steam boiler and cogeneration plant at Rice University was conducted. The analysis included many components of the plant including piping, valves, boilers, turbines, ... 
[20110702] Selective epitaxial growth techniques to integrate highquality germanium on silicon
Highquality GeonSi heterostructures have been actively pursued for many advanced applications, including nearinfrared photodetectors, highmobility field effect transistors, and virtual substrates for integrating IIIV ... 
[20120703] Selective salt recovery from reverse osmosis concentrate using interstage ion exchange
A treatment process for reverse osmosis concentrate was developed to recover selected salts and increase fresh water recovery. The process utilizes cation and anion exchange to exchange all ions in the concentrate stream ... 
[20080709] Semiconductor yield analysis and prediction using a stochastic layout sensitivity model
Spot defects represent the main challenge for enhancement of semiconductor manufacturing yield. As a result, the yield of modern integrated circuits is associated with the layout sensitivity to defects. The term “layout ... 
[20110208] Sensitivity of MEPDG Using Advanced Statistical Analyses
Recently, pavement design has changed from old method based on empirical relation to a new method called Mechanistic Empirical Pavement Design Guide (MEPDG). It is essential to perform a detailed sensitivity analysis of ... 
[20120827] Sensitivity study of turbulent flow simulations over a rotating disk
With increasing demand for renewable energy, there is a need for accurate and reliable simulations of a flow around a wind turbine. To be of use as an engineering design and planning tool, such simulations should be ... 
[20120131] Seven Deadly Factors Associated with Technology Company Failure
Seven factors associated with technology company failure (or death) are described along with features that distinguish each factor. A company is commonly defined to have failed when it passes through a stage of insolvency ... 
[20110830] Short & long term properties of selfconsolidating concrete incorporating fly ash and local aggregate
Selfconsolidating concrete (SCC) is a high performance concrete that flows under its own weight so that filling forms containing congested reinforcement is possible without mechanical vibration within placements. There ... 
[20070909] SIMD pipelined processor implemented on a FPGA
The goal of this thesis was to create a processor using VHDL that could be used for educational purposes as well as a stepping stone in creating a reconfigurable system for digital signal processing or image processing ... 
[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)
