Automated Algorithm For The Identification Of Artifacts In Mottled And Noisy Images, Onome Augustine Ugbeme, Eli S. Saber, Wencheng Wu, Kartheek Chandu Dec 2006

Automated Algorithm For The Identification Of Artifacts In Mottled And Noisy Images, Onome Augustine Ugbeme, Eli S. Saber, Wencheng Wu, Kartheek Chandu

Articles

We describe a method for automatically classifying image-quality defects on printed documents. The proposed approach accepts a scanned image where the defect has been localized a priori and performs several appropriate image processing steps to reveal the region of interest. A mask is then created from the exposed region to identify bright outliers. Morphological reconstruction techniques are then applied to emphasize relevant local attributes. The classification of the defects is accomplished via a customized tree classifier that utilizes size or shape attributes at corresponding nodes to yield appropriate binary decisions. Applications of this process include automated/assisted diagnosis and repair of …

The Complexity Of Computing The Size Of An Interval, Lane A. Hemaspaandra, Christopher M. Homan, Sven Kosub, Klaus W. Wagner Dec 2006

The Complexity Of Computing The Size Of An Interval, Lane A. Hemaspaandra, Christopher M. Homan, Sven Kosub, Klaus W. Wagner

Articles

Given a p-order A over a universe of strings (i.e., a transitive, reflexive, antisymmetric relation such that if (x, y) ∈ A then |x| is polynomially bounded by |y|), an interval size function of A returns, for each string x in the universe, the number of strings in the interval between strings b(x) and t(x) (with respect to A), where b(x) and t(x) are functions that are polynomial-time computable in the length of x. By choosing sets of interval size functions based on feasibility requirements for their underlying p-orders, we obtain new characterizations of complexity classes. We prove that the …

Re-Examining The Politics Of U.S. Intervention In Early 20th Century Nicaragua: José Madriz And The Conservative Restoration, Yann Kerevel Dec 2006

Re-Examining The Politics Of U.S. Intervention In Early 20th Century Nicaragua: José Madriz And The Conservative Restoration, Yann Kerevel

Research Papers

This research re-examines the U.S. intervention in Nicaragua in 1909-10. Most literature of this period argues that the United States forced the dictator Zelaya out of office in 1909; however, I contend that the argument that U.S. intervention caused the fall of Zelaya does not clearly match up to the historical record. Instead, I argue it is much more compelling to examine U.S. policy toward José Madriz to understand the impact of the intervention. It is clear that U.S. policy was the decisive factor in the fall of Madriz, while it is less convincing in the case of Zelaya.

Performance Comparison Of Hyperspectral Target Detection Algorithms, Adam Cisz Dec 2006

Performance Comparison Of Hyperspectral Target Detection Algorithms, Adam Cisz

Theses

This thesis performs a performance comparison on existing hyperspectral target detection algorithms. The algorithms chosen for this analysis include multiple adaptive matched filters and the physics based modeling invariant technique. The adaptive matched filter algorithms can be divided into either structured (geometrical) or unstructured (statistical) algorithms. The difference between these two categories is in the manner in which the background is characterized. The target detection procedure includes multiple pre-processing steps that are examined here as well. The effects of atmospheric compensation, dimensionality reduction, background characterization, and target subspace creation are all analyzed in terms of target detection performance. At each …

The Incorporation Of Atmospheric Variability Into Dirsig, Brian Dobbs Dec 2006

The Incorporation Of Atmospheric Variability Into Dirsig, Brian Dobbs

Theses

The goal of this research can be divided into two main areas. The first is to improve the existing manner in which DIRSIG samples and references the atmosphere. The second is to give DIRSIG the ability to incorporate atmospheric inhomogeneities, as well as the ability to accurately model them. DIRSIG has limitations in how it currently samples the atmosphere. From a geometric standpoint, it does not fully sample the energy which is scattered by the atmosphere towards the sensor (upwelled radiance). There are also other geometric issues which lead to inaccurate modeling results. One significant inaccuracy is the fact that …

A Program Of Self-Esteem Development For Deaf Children In Rural Areas, Candi Daviton Dec 2006

A Program Of Self-Esteem Development For Deaf Children In Rural Areas, Candi Daviton

Theses

Deaf children in rural areas often lack the development of self-esteem essential to their overall development of social and academic skills. Deaf children in rural communities generally have low interpersonal communication and leadership skills. Being isolated with no role model for their identification (deafness) could limit their language acquisition and identity development. The purpose of this project is to develop a special curriculum project which would help initiate a program that would enable deaf children in rural areas to develop self-esteem skills through a one week summer camp program focusing on learning about themselves and related essential self-esteem skills through …

Discrete Asymptotic Abstractions Of Hybrid Systems, Chaouki T. Abdallah, Jorge L. Piovesan, Herbert G. Tanner Dec 2006

Discrete Asymptotic Abstractions Of Hybrid Systems, Chaouki T. Abdallah, Jorge L. Piovesan, Herbert G. Tanner

Electrical & Computer Engineering Faculty Publications

In this paper we introduce the notion of finite time mode abstraction to relate a hybrid automaton to a timed automaton that preserves the stability and reachability properties of the former. The abstraction procedure discards the continuous dynamics of each mode in the hybrid automaton completely, keeping only the information about the maximum time in which the continuous state makes a discrete jump. This information is used to construct a timed automaton, based on the original hybrid automaton, and to prove that the stability and reachability properties of the original system are retained in the abstract timed automaton. In the …

We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints on cosmological parameters from the Wilkinson Microwave Anisotropy Probe (WMAP). We employ a matrix-based power spectrum estimation method using Pseudo-Karhunen-Lo`eve eigenmodes, producing uncorrelated minimum-variance measurements in 20 k-bands of both the clustering power and its anisotropy due to redshift-space distortions, with narrow and well-behaved window functions in the range 0.01 h/Mpc < k < 0.2 h/Mpc. Results from the LRG and main galaxy samples are consistent, with the former providing higher signal-to-noise. Our results are robust to omitting angular and radial density fluctuations and are consistent between different parts of the sky. They provide a striking confirmation of the predicted large-scale CDM power spectrum. Combining only SDSS LRG and WMAP data places robust constraints on many cosmological parameters that complement prior analyses of multiple data sets. The LRGs provide independent cross-checks on m and the baryon fraction in good agreement with WMAP. Within the context of flat CDM models, our LRG measurements complementWMAP by sharpening the constraints on the matter density, the neutrino density and the tensor amplitude by about a factor of two, giving m = 0.24±0.02 (1 ), Pmν < 0.9 eV (95%) and r < 0.3 (95%). Baryon oscillations are clearly detected and provide a robust measurement of the comoving distance to the median survey redshift z = 0.35 independent of curvature and dark energy properties. Within the CDM framework, our power spectrum measurement improves the evidence for spatial flatness, sharpening the curvature constraint tot = 1.05±0.05 from WMAP alone to tot = 1.003±0.010. Assuming tot = 1, the equation of state parameter is constrained to w = −0.94±0.09, indicating the potential for more ambitious future LRG measurements to provide precision tests of the nature of dark energy. All these constraints are essentially independent of scales k > 0.1h/Mpc and associated nonlinear complications, yet agree well with more aggressive published analyses where nonlinear modeling is crucial.

Graphical Microcode Simulator With A Reconfigurable Datapath, Brian Vanburen Dec 2006

Graphical Microcode Simulator With A Reconfigurable Datapath, Brian Vanburen

Theses

Microcode is a symbolic way to simplify control design that allows changing, testing and updating the control unit of processors. By changing the microcode, the same datapath can be used for an entirely different application, such as supporting a completely different instruction set. For these reasons, a majority of control units in modern day processors are microcoded. The object was to investigate and implement a graphical microcode simulator with a reconfigurable datapath and microcode format. By allowing a wide configuration of the datapath, many types of logical processors can be designed and simulated. The resulting implemented simulator is able to …

The Acs Virgo Cluster Survey. Xiv. Analysis Of Color-Magnitude Relations In Globular Cluster Systems, Steffen Mieske, Andres Jordan, Patrick Cote Dec 2006

The Acs Virgo Cluster Survey. Xiv. Analysis Of Color-Magnitude Relations In Globular Cluster Systems, Steffen Mieske, Andres Jordan, Patrick Cote

Articles

We examine the correlation between globular cluster (GC) color and magnitude using HST/ACS imaging for a sample of 79 early-type galaxies (−21.7 < MB < −15.2 mag) with accurate surfacebrightness fluctuation distances from the ACS Virgo Cluster Survey. Using the KMM mixture modeling algorithm, we find a highly significant correlation, z ≡ d(g−z) dz = −0.037 ± 0.004, between color and magnitude for the subpopulation of blue GCs in the co-added GC color-magnitude diagram of the three brightest Virgo cluster galaxies (M49, M87 and M60). The sense of the correlation is such that brighter GCs are redder than their fainter counterparts. For the single GC systems of M87 and M60, we find similar correlations; M49 does not appear to show a significant trend. There is no correlation between (g − z) and Mz for GCs belonging to the red subpopulation. The correlation g ≡ d(g−z) dg for the blue subpopulation is much weaker than z. Using Monte Carlo simulations, we attribute this finding to the fact that the blue subpopulation in Mg extends to higher luminosities than does the red subpopulation, which biases the KMM fit results. The highly significant correlation between color and Mz, however, is a real effect: this conclusion is supported by biweight fits to the same color distributions. We identify two environmental dependencies which influence the derived color-magnitude relation: (1) the slope of the color-magnitude relation decreases in significance with decreasing galaxy luminosity, although it remains detectable over the full luminosity range of our sample; and (2) the slope is stronger for GC populations located at smaller galactocentric distances. These characteristics suggest that the observed trend is, at least partially, shaped by external agents. We examine several physical mechanisms that might give rise to the observed color-magnitude relation including: (1) presence of contaminants like super-clusters, stripped galactic nuclei, or ultra-compact dwarfs; (2) accretion of GCs from low-mass galaxies; (3) stochastic effects; (4) the capture of field stars by individual GCs; and (5) GC self-enrichment. Although none of these scenarios offers a fully satisfactory explanation of the observations, we conclude that self-enrichment and field-star capture, or a combination of these processes, offer the most promising means of explaining our observations.

Impact Of Foliar Fungicides On Yield And Net Returns In Soybeans, Benjamin L. Spinks Dec 2006

Impact Of Foliar Fungicides On Yield And Net Returns In Soybeans, Benjamin L. Spinks

Theses and Dissertations

Field studies were conducted in 2003, 2004, and 2005 in the Mississippi delta at 12 locations across common production practices to evaluate the impact of 12 single applications of fungicides at the R3 and R5 growth stage on soybean yield, seed quality, and net returns. Averaged across locations, azoxystrobin alone and mixed with other fungicides increased yields 161 to 343 kg/ha compared to the nontreated control. Fungicide applications made at R3-R4 were more efficacious and resulted in larger yield increases than applications made at R5-R6. Plots treated at the R3-R4 growth stage with 0.11kg ai/ha azoxystrobin alone or in combination …

Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain Dec 2006

Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain

Theses and Dissertations

Traditional clustering is typically based on a single feature set. In some domains, several feature sets may be available to represent the same objects, but it may not be easy to compute a useful and effective integrated feature set. We hypothesize that clustering individual datasets and then combining them using a suitable ensemble algorithm will yield better quality clusters compared to the individual clustering or clustering based on an integrated feature set. We present two classes of algorithms to address the problem of combining the results of clustering obtained from multiple related datasets where the datasets represent identical or overlapping …

Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis Dec 2006

Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis

Theses and Dissertations

Heart valve disease is currently one of the leading forms of heart disease. Current literature has shown that endothelin I, angiotension II and 5-HT are vasoactive agents which cause concentration dependent contractions in aortic valve leaflet tissue. This study tested the mechanical properties of leaflets cut in the radial direction after they were exposed to the agents at varied concentrations or for 0.5, 6 or 24 hours. The elastic modulus, ultimate tensile strength and the yield strength were calculated. In the time trials the elastic modulus and the ultimate tensile strength both showed a significant increase at 24-hours. However, there …

Functional Role Of Recombinant Cysteine Protease On Spodoptera Frugiperda Peritrophic Matrix, Srinidi Mohan Dec 2006

Functional Role Of Recombinant Cysteine Protease On Spodoptera Frugiperda Peritrophic Matrix, Srinidi Mohan

Theses and Dissertations

Fall armyworm larvae (FAW), which are serious pests in the southern United States, show retarded growth when they feed on insect-resistant maize inbreds Mp704 and Mp708. These maize genotypes are not only resistant to FAW, but to a number of other lepidopteran pests. In these genotypes, a unique, extracellular, 33-KDa cysteine protease (Mir1-CP) rapidly accumulates in the whorl in response to insect feeding. Initial morphological studies on larvae feeding on resistant maize plants over-expressing the cysteine protease showed severe damage in insect?s first line of defense, the peritrophic matrix (PM). But it is not known whether the cysteine protease has …

Reduction Of Volatile Organic Compounds Emitted During Kiln Drying Of Southern Yellow Pine Lumber, Joseph Martin Dahlen Dec 2006

Reduction Of Volatile Organic Compounds Emitted During Kiln Drying Of Southern Yellow Pine Lumber, Joseph Martin Dahlen

Theses and Dissertations

The objective of the research is to reduce the volatile organic compounds (VOCs) emitted during kiln drying of southern yellow pine (SYP) lumber. Three treatment methods were explored to determine their effect on VOC emissions. The three methods were configured at the air exhaust of a pilot-scale dry kiln. 1) A steel reactor containing copper tubing heated to 100°, 200°, and 240° Celsius was evaluated. Temperature did not statistically affect VOC emissions (p-value = 0.1674). The average reduction of VOCs at 240° C was seven percent. 2) The use of hydrogen peroxide and ultra-violet (UV) light did not reduce VOCs …

Development Of Power Flow With Distributed Generators And Reconfiguration For Restoration Of Unbalanced Distribution Systems, Sarika Khushalani Dec 2006

Development Of Power Flow With Distributed Generators And Reconfiguration For Restoration Of Unbalanced Distribution Systems, Sarika Khushalani

Theses and Dissertations

With the increasing interest in distribution automation, distribution power flow is important for applications like VAR planning, switching, state estimation and especially optimization. Typically, a distribution system originates at a substation and continues to a lower voltage for delivery to the customers. There are several tools for transmission system analysis. These tools include Newton Raphson, Gauss Seidel and fast decoupled techniques. These techniques however sometimes fail to converge when applied to distribution systems due to their higher resistance/reactance (R/X) ratio of the lines, making them ill conditioned. Distribution systems typically have a radial topological structure where the loads are not …

Multi-Agent Based Control And Reconfiguration For Restoration Of Distribution Systems With Distributed Generators, Jignesh M. Solanki Dec 2006

Multi-Agent Based Control And Reconfiguration For Restoration Of Distribution Systems With Distributed Generators, Jignesh M. Solanki

Theses and Dissertations

Restoration entails the development of a plan consisting of opening or closing of switches, which is called reconfiguration. This dissertation proposes the design of a fast and efficient service restoration with a load shedding method for land-based and ship systems, considering priority of customers and several other system operating constraints. Existing methods, based on centralized restoration schemes that require a powerful central computer, may lead to a single point of failure. This research uses a decentralized scheme based on agents. A group of agents created to realize a specific goal by their interactions is called a Multi-Agent System (MAS). Agents …
