The Consideration Of Camera Testing For Accurate Color Reproduction Within Museums And Institutions, Natalie Russo

Theses

The need for color accurate digital images for fine art reproduction is a reality faced by art museums and institutions around the world. It is the goal of most institutions to replace old, sometimes used and abused, transparency archives with digital image archives; many institutions have already begun this work. A number of different imaging systems with varied workflows, some idiosyncratic, are being used for this work. There is, therefore, an urgent need for the development and sharing of working methods that will ensure efficient, consistent, and color accurate results. These workflows must use camera systems to their fullest capability. …

Assessing The State Of Web Accessibility, Laura Cook

Theses

People with disabilities continue to be at a disadvantage in terms of opportunities on the Web. Federal laws and state policies help govern website design for federal and state agencies, but their impact thus far is unclear. This thesis addresses the issue of web accessibility and examines the compliance of state websites. A sample of state websites was evaluated for accessibility with two different methods: (1 ) using two automated accessibility validation checkers (Bobby and Entre), and (2) using a process of gradually degrading the web pages down to a text-only page. A survey was developed and administered to web …

Graph Reconstruction Numbers, Brian Mcmullen

Theses

The Reconstruction Conjecture is one of the most important open problems in graph theory today. Proposed in 1942, the conjecture posits that every simple, finite, undirected graph with more than three vertices can be uniquely reconstructed up to isomorphism given the multiset of subgraphs produced by deleting each vertex of the original graph. Related to the Reconstruction Conjecture, reconstruction numbers concern the minimum number of vertex deleted subgraphs required to uniquely identify a graph up to isomorphism. During the summer of 2004, Jennifer Baldwin completed an MS project regarding reconstruction numbers. In it, she calculated reconstruction numbers for all graphs …

The Mainstream Press: Then And Now Has The Prominence Of Sensational News Changed In 100 Years?, Kathleen Marchaesi

Theses

The present research explores the levels of sensational news reporting in three distinct periods of journalism history by examining the largest mainstream newspaper in America, The New York Times, during the yellow journalism, jazz journalism and modern eras. The front pages of a representative sample of the newspaper were analyzed to determine the extent to which prominence of sensational news topics in the modern press differs from that of the yellow and jazz eras. The style of sensational reporting was examined to determine if the treatment of news has changed. The results of a content analysis indicate that readers are …

An Evolutionary Computation Approach To Optimization Of Isoelectric Point Prediction In Proteins, Chris Parkin

Theses

Computational biology has attacked the problem of isoelectric point prediction with little success, achieving a rough accuracy level of only 30%. In 2005, Matthew Conte performed a study focused on the relationship between sequence characteristics and isoelectric point prediction accuracy. Results indicated that charges between adjacent amino acids could have a significant impact on the overall predicted pi for the protein. In this study we introduce an evolutionary computation approach aimed at accounting for these problem dipeptides. For each possible dipeptide involving charged amino acids (7 chargeable groups -> 49 possibilities), the algorithm predicts a pKa value that, when included …

It also proved to be a milestone in the establishment of the use of computers in rational drug design.

Evolutionary computation is a commonly used computational approach that has been successfully applied to a variety of fields ranging from engineering to life science. The main reason for its effectiveness is that it is driven by the principles of evolution. A genetic …

A Messaging System To Handle Semantic Dissonance, Ashish Rathod

Theses

Enterprises have been compelled to share their data internally and externally, but creating a consistent view of enterprise data has been challenging. Within a typical enterprise, each division uses its own domain specific data model and schema, and different enterprises obviously use their own data models and schema. Integrating these diverse data models and schemas, which have both syntactic and semantic differences, tends to be complex, slow, and inaccurate. Syntactic differences, i.e., differences in names or layout, have received substantial attention in research. Semantic dissonance simply means that the structure may be similar (or even the same) but the meaning …

Acoustic Classification Using Independent Component Analysis, James Brock

Theses

This thesis research investigates and demonstrates the feasibility of performing computationally efficient, high-dimensional acoustic classification using Mel-frequency cepstral coefficients and independent component analysis for temporal feature extraction. A process was developed to calculate Mel-frequency cepstral coefficients from samples of acoustic data grouped by either musical genre or spoken world language. Then independent component analysis was employed to extract the higher level temporal features of the coefficients in each class. These sets of unique independent features represent themes, or patterns, over time that are the underlying signals in that class of acoustic data. The results obtained from this process clearly show …

Relationship Of Human Figure Drawing With Executive Functioning And Achievement, Julie M. Miller

Theses

The purpose of the study was to investigate the relationship between aspects of children’s human figure drawings to their executive functioning and academic achievement. Participants consisted of 80 third and fourth graders, ages 8 to 10 years, along with their parents.

Extraction And Interaction Analysis Of Foreground Objects In Panning Video, Raja Jain

Theses

In this work, moving foreground objects are extracted from video. The video camera can be either stationary or panning. The motion information extracted from consecutive frames of video is used for object segmentation, and an appearance model of the moving object is created. No assumptions are made concerning the object model, resulting in segmented objects of varying shapes and sizes. Finally, relationships between objects in the image are evaluated toward the goal of higher level understanding of videos.

A Biologically Plausible System For Detecting Saliency In Video, David Burlone

Theses

Neuroscientists and cognitive scientists credit the dorsal and ventral pathways for the capability of detecting both still salient and motion salient objects. In this work, a framework is developed to explore potential models of still and motion saliency and is an extension of the original VENUS system. The early visual pathway is modeled by using Independent Component Analysis to learn a set of Gabor-like receptive fields similar to those found in the mammalian visual pathway. These spatial receptive fields form a set of 2D basis feature matrices, which are used to decompose complex visual stimuli into their spatial components. A …

Application Of Shifted Delta Cepstral Features For Gmm Language Identification, Jonathan Lareau

Theses

Spoken language identifcation (LID) in telephone speech signals is an important and difficult classification task. Language identifcation modules can be used as front end signal routers for multilanguage speech recognition or transcription devices. Gaussian Mixture Models (GMM's) can be utilized to effectively model the distribution of feature vectors present in speech signals for classification. Common feature vectors used for speech processing include Linear Prediction (LP-CC), Mel-Frequency (MF-CC), and Perceptual Linear Prediction derived Cepstral coefficients (PLP-CC). This thesis compares and examines the recently proposed type of feature vector called the Shifted Delta Cepstral (SDC) coefficients. Utilization of the Shifted Delta Cepstral …

Europa: A Framework For Writing Reusable Automated Tests For C# Components, Christian Castillo

Theses

One of the main goals of software construction is reusability. Component-based (CB) development is a new paradigm that promises to facilitate the reuse of software elements. The component-based model attempts to create an analogy with computer hardware. The idea is that software applications should be developed by assembling existing components rather than reinventing solutions to problems that have already been solved. In this paradigm, a component consumer is faced with the problem of determining if a given component meets his expectations. Testing the component can help answer this question. The component consumer may have to apply the same test cases …

Streak Detection In Mottled And Noisy Images, Hector Santos

Theses

This thesis describes an algorithm for detecting streaks in printed images using adaptive window-based image projections and maximization of mutual information. To this effect, projections are computed across the entire image at different window sizes. The traces collected from the projections are correlated using maximization of mutual information to pinpoint streak locations and widths using a peak detection algorithm. Finally, for a given peak, the window size is changed adaptively to identify and locate the intensity and length of the corresponding streak while maximizing signal to noise ratio. Results on synthetic and real-life images are provided to demonstrate the effectiveness …

Optimal Design Of Ink Spectra For Multiple-Ink Color Reproduction, Yongda Chen

Theses

Conventional four-color printing systems are limited by a relative small color gamut, poor color constancy, and a high degree metamerism. In this dissertation, these problems were addressed by increasing the ink number, optimizing the spectral ink curves, and the lookup tables for multiple-ink printing. First, a computer simulation was performed to investigate the optimum combinations of different ink number to maximize the color gamut for halftoning printing. By analyzing the color gamuts achieved by real ink sets and virtual ink sets, the conclusions were drawn that the color gamut can be improved by increasing ink number and optimizing spectral ink …

Plane Elasticity Using Airy Stress Functions, Matthew David Roman

Theses

Given a three dimensional solid element in a state of plane stress or plane strain with conservative body forces, the stress components are equal to the appropriate second order partial derivatives of a bi-harmonic function, ϕ , called an Airy Stress Function. It follows that the stress components automatically satisfy the equilibrium conditions.

The function ϕ depends on both the geometry of the body and the loading, which leaves infinite possible stress functions to be developed. As thesis work, I have researched and collected currently existing Airy Stress Functions, made plots of thier stress fields in order to gain a …

Computational Fluid Dynamics And Experimental Studies Of An Energy-Efficient Uv Disinfection System For Water Treatment, Nancy Goenawan

Theses

In typical commercial UV treatment system, water is flushed through a reactor vessel, where a UV lamp irradiates the flowing water. The distribution of the UV dose is extremely non-uniform. At distances away from the light, the dosage will be too low to kill the microorganism. As a result more power is needed in such a system for an effective treatment. A new energy-efficient UV disinfection system, named "Off Center", was designed, developed, and tested. This "Off Center" system consists of a UV bulb that has been relocated from its traditional central location to a location closer to the 4-in …
