Investigation Of Minimum Response For Damage Assessment, Jeffrey Kirk Jul 2005

Investigation Of Minimum Response For Damage Assessment, Jeffrey Kirk

Mechanical and Aerospace Engineering Theses - Archive

Assessment of structural damage based on changes in vibratory response characteristics has been researched for many years, with much attention directed toward the use of modal parameters. Modal responses contribute to form points of local minima in the frequency response of a system. The frequency and amplitude values corresponding to these points of minimum response can be analytically determined, experimentally measured, and shown to exhibit sensitivity to damage. This work was performed to investigate the possible contribution that explicitly targeted minimum response information could provide in a damage detection process. A simple 6-DOF discrete spring-mass system was used to conduct …

Deformable Haptic Models For Surgical Simulation, Xiuzhong Wang Jul 2005

Deformable Haptic Models For Surgical Simulation, Xiuzhong Wang

Electrical Engineering Dissertations - Archive

Surgical simulation is in great need for surgical training, analysis, planing and rehearsal. The core of this simulation is the deformable models for the organs. The deformable model must provides both realistic visual effects (graphics) and high fidelity force feedback (haptics) in real time, without distractive visual artifacts and misleading tactile clues. In view of the requirement of physical accuracy, physically based deformable models are favorable for surgical simulation. Physically based deformable modeling has been a serious research topic for about twenty years in the computer graphics community. For computer animation, a great deal of work has been done so …

The Least-Squares Finite Element Method For Grid Deformation And Meshfree Applications, Dionisio Laeber Fleitas Jul 2005

The Least-Squares Finite Element Method For Grid Deformation And Meshfree Applications, Dionisio Laeber Fleitas

Mathematics Dissertations - Archive

Grid adaptation is often needed to improve the numerical solution of a Partial Differential Equation (PDE), due to, for example, shock waves and boundary layers. In moving boundary problems, the grid needs to be regenerated or adapted to fit the new domain. In this work, a LSFEM deformation method is developed for grid generation on fixed or moving domains. The LSFEM is a finite-elements method which seeks to minimize the PDE residual equation through the least-squares method. A new class of numerical methods currently being researched is the meshfree methods, in which the main goal is to numerically solve PDEs …

Automating Inhabitant Interactions In Home And Workplace Environments Through Data-Driven Generation Of Hierarchical Partially-Observable Markov Decision Processes, Gregory Michael Youngblood Jul 2005

Automating Inhabitant Interactions In Home And Workplace Environments Through Data-Driven Generation Of Hierarchical Partially-Observable Markov Decision Processes, Gregory Michael Youngblood

Computer Science and Engineering Dissertations - Archive

Markov models provide a useful representation of system behavioral actions and state observations, but they do not scale well. Utilizing a hierarchy and abstraction through hierarchical hidden Markov models (HHMMs) improves scalability, but these structures are usually constructed manually using knowledge engineering techniques. We introduce a new method of automatically constructing HHMMs using the output of a sequential data-mining algorithm, Episode Discovery, and apply it to solving automation problems in the intelligent environment domain. Repetitive behavioral actions in sensor rich environments such as smart homes can be observed and categorized into periodic and frequent episodes through data-mining techniques utilizing the …

The Reflection Property In Normed Linear Planes With Applications To Generalized Conics, Edward J. O'Neill, Mostafa Ghandehari

Mathematics Technical Papers - Archive

The ancient Greek mathematician Heron was the first to solve the problem of finding the shortest path from point A to point B on one side of the line L, subject to the condition that the path goes from A to L and then to B (figure 1). Figure 1. His solution involved going from A to point R on L and then to B such that the line segments AR and BR make equal angles with L. This is exactly the path a light ray from A to B if L were a mirror. Heron included this proposition in …

The 2d4d Ratio And Cyclic Shifts As Predictors Of Self-Perceived Quality And Permissiveness, Jason Cole Lyons Jul 2005

The 2d4d Ratio And Cyclic Shifts As Predictors Of Self-Perceived Quality And Permissiveness, Jason Cole Lyons

Psychology Dissertations - Archive

The following paper discusses the findings from background research leading up to a discussion of findings from the present study. The relationships between female sexual permissiveness and female's self-perceived quality (SPQ) as a potential mate, male quality, and female age were evaluated. A woman's SPQ was predicted to correlate negatively with acceptance of sexual propositions but the data failed to support the prediction. It was further predicted that when male quality was relatively greater than female SPQ, the probability of accepting a casual sex proposition would be greater. Partial support for this prediction was found. Older females were more likely …

A First-Principles Study On Bulk Cuo: Electronic Structures And Native Point Defects, Dangxin Wu Jul 2005

A First-Principles Study On Bulk Cuo: Electronic Structures And Native Point Defects, Dangxin Wu

Physics Theses - Archive

In this thesis, we have performed a first-principles study on strongly correlated monoclinic cupric oxide (CuO) by using the LSDA+U method implemented in the PAW method. Based on the optimized structural parameters, which are in good agreement with the experimental data, the electronic structure and the magnetic properties are obtained. Our calculations show that CuO is a semiconducting material with an indirect gap of about 1.0 eV. The semiconducting nature of CuO from our calculations is consistent with many experiments, but is qualitatively different from the LSDA calculations which incorrectly predict CuO to be metallic. The indirect gap of 1.0 …

Environmental, Genetic, And Maternal Effects On Life-History Traits Of The Striped Ground Cricket, Allonemobius Socius, Diana Lea Huestis Jun 2005

Environmental, Genetic, And Maternal Effects On Life-History Traits Of The Striped Ground Cricket, Allonemobius Socius, Diana Lea Huestis

Biology Theses - Archive

Organismal fitness is affected by environmental and genetic factors. More importantly, an interaction between an individual's genotype and current environmental conditions influences the success of that individual in its environment. Significant geographic and environmental correlates of allele frequencies at the Idh-1 locus, combined with a significant genotype-by-environment (GxE) interaction between Idh-1 genotype and temperature that affected fitness of Allonemobius socius, support the hypothesis that allele distributions in this species are the result of natural selection on performance of different genotypes at different temperatures. Additionally, I found that an interaction between parental diapause history and egg-incubation temperature affected the proportion of …

The Parody Of Romance, Tara Donalson Jun 2005

The Parody Of Romance, Tara Donalson

English Theses - Archive

In Reading the Romance: Women, Patriarchy, and Popular Literature, Janice A. Radway studies the romance formula, identifying a set of generic criteria which offer its readers escapist purposes. Christian writers have established their own formula on the romance. In my thesis, I look at the parallel formulas found in secular and inspirational romance fiction, searching how inspirational romance evangelizes and gives spiritual instruction to its readers. Secular romance creates stories which explore the idea of everlasting love. They create a relationship between a flawed hero and innocent heroine who fall in love at first sight; out of this imperfect relationship …

A Framework For Model Checking Object Oriented Security Protocol Implementations, Parikshit Singh

Computer Science and Engineering Theses - Archive

With the rapid growth of the Internet, more and more vendors see the Internet as a viable marketplace. Since the Internet is public, providing security in the presence of malicious intruders has become paramount. Security protocols have been proposed to protect systems. These protocols work by exchanging messages, many of which are encrypted. Though it may take a long time for an intruder to break the underlying encryption employed by the protocol, it is possible for the intruder to intervene in the authentication process. It may take years before a crucial loophole is discovered in a security protocol. Until then, …

A Discourse Analysis Of 1 Peter, Ervin Ray Starwalt May 2005

A Discourse Analysis Of 1 Peter, Ervin Ray Starwalt

Linguistics & TESOL Dissertations - Archive

The study focuses on two problems. The first concerns the structure of the text. The text is considered to be notoriously difficult to outline. The second problem is the function of the participle in 1 Peter. The letter is considered to contain some of the classical examples in the New Testament of the imperatival participle (e.g. 2:18; 3:1, 7, 9), the participle used independently in place of a finite imperative verb. The text is analyzed in terms of salience. Generally, commanding clauses, primarily indicated by the presence of imperative verbs, are those clauses which move the argument along. Locally, other …

Consonant Cluster Simplification In Korean Codas: Language-Internal And Language-External Constraints Interface With Reference To Optimality Theory, Youn-Jeoung Choi May 2005

Consonant Cluster Simplification In Korean Codas: Language-Internal And Language-External Constraints Interface With Reference To Optimality Theory, Youn-Jeoung Choi

Linguistics & TESOL Dissertations - Archive

In Korean, when a morpheme contains a coda cluster in its underlying form (such as /salm/‘life,’ /hulk/‘soil’), we observe two outcomes in its surface representation. In cases when the morpheme followed by either another consonant or by a word boundary, the cluster is simplified by deleting one consonant. However, if a vowel-initial morpheme follows the underlying cluster, the second member of the cluster assumes the role of a syllable onset. Contrary to prescriptive accounts in which both the deleted consonant and the results of resyllabification are claimed to be completely predictable, observation of contemporary Korean usage suggest that there is …
