Information Retrieval And Mining In High Dimensional Databases, Xiong Wang

Dissertations

This dissertation is composed of two parts. In the first part, we present a framework for finding information (more precisely, active patterns) in three dimensional (3D) graphs. Each node in a graph is an undecoraposable or atomic unit and has a label. Edges are links between the atomic units. Patterns are rigid substructures that may occur in a graph after allowing for an arbitrary number of whole-structure rotations and translations as well as a small number (specified by the user) of edit operations in the patterns or in the graph. (When a pattern appears in a graph only after the …

Axisymetric Vibrations Of Homogeneous And Sandwich Spherical Shells With A Hole At The Center, Wai-Kwong Wong

Dissertations

Based on Hamilton's principle and the theory of elasticity, both linear and nonlinear governing equations of motion are derived for elastic spherical shells. Most of the analysis is focused on the free axisymmetric vibrations of homogeneous and sandwich shallow spherical shells. The nonlinear behavior, which allows for small deflections, is also discussed.

The linear vibrations of homogeneous and sandwich shallow spherical shells with a hole at the center are investigated with emphasis placed on the effect of thickness-shear deformation and rotatory inertia. The effects of curvature and the size of the central hole are studied for free axisymmetric motions of …

The Supplemental Effects Of Feedback On Productivity Under Individual Incentives, Barbara R. Bucklin

Participants were seven college students who performed a computerized work task called SYNWORK. SYNWORK presented four sub-tasks concurrently: memory, arithmetic, visual monitoring and auditory monitoring. Participants earned points for correct responses. Dependent variables were the total number of points earned, percent correct, and time-on-task. An ABAC within-subject reversal design was used with A = individual monetary incentives without feedback, B = individual monetary incentives with end-of-session feedback, and C = hourly pay with end-of session …

The Victim Rights Movement: A Social Constructionist Examination, Angela Renee Evans

Dissertations

What has been termed the victim rights movement has made great progress in promoting legislative changes regarding victim rights in the United States. This research examines the victim rights movement from a social constructionist perspective by focusing on two pieces of federal legislation passed in the 1980s: the Victim and Witness Protection Act of 1982 and the Victims of Crime Act of 1984. Using the social constructionist perspective, the research examines who was involved in the claims-making activities and which claims were most likely to be heard and acted upon. Rather than seeing social movements as the result of some …

Capital Punishment: A New Perspective On Race And Ethnic Differences In Punishment And Death Sentence Outcomes, Martin G. Urbina

Dissertations

A review of the existing literature on death sentence outcomes (i.e., executions, commutations) shows evidence of discrimination against minority defendants (e.g., African Americans). Prior studies, however, have followed a Caucasian/African American and/or execution/commutation approach. Latino defendants have either been excluded or treated as a monolithic group. Thus, little is known about death sentence outcomes for Latinos, whose experiences differ from those of African Americans and Caucasians. Additionally, little is known about the treatment of the various ethnic groups (e.g., Cubans, Mexicans) that constitute the Latino community. And, since the focus has been on executions and/or commutations, little is known about …

A Preliminary Investigation Of The Acceptability And Effectiveness Of Computer-Based Adjunctive Parent Training For Child Noncompliance, Dwayne M. Munneke

Dissertations

Noncompliance with parent requests is a commonly reported behavior problem for clinic-based child referrals. Parent skills training has been empirically demonstrated as an effective treatment for helping parents increase positive child behaviors and decrease negative behaviors. Unfortunately, many therapists and agencies are unable to implement parent-training programs due to limited therapist training, limited economic resources, or long waiting lists.

Adjunctive, computer-based, treatment programs have become increasingly popular in both research and clinical settings for facilitating psychological assessment and intervention. This project involved the development and preliminary investigation of the effectiveness and acceptability of a computer-based program designed to supplement therapist-delivered …

The Gothic Wanderer: From Transgression To Redemption, Tyler R. Tichelaar

Dissertations

The Gothic wanderer of British fiction originated during the French Revolution. During the nineteenth century, the figure evolved from one of transgression into a symbol of redemption. While Romantic poets created wanderer figures to celebrate rebellion, Gothic novelists utilized the wanderer figure to explore the psychology of transgression. The Gothic interpreted the French Revolution as a transgression against God and His ordained institutions. The wanderer figure expressed the anxieties of the revolutionary period and the attempt to imagine a political world not based upon monarchy. Gothic novelists also questioned what effects the French Revolution might have upon England. The overthrow …

Whatever Shines: Poems, Kathleen Mcgookey

Dissertations

The poems in my manuscript can be divided into two groups: poems in verse and prose poems. The majority are prose poems. Though I did not set out to write in the prose poem form, I’ve become more and more attracted to it, eventually seeking what Baudelaire sought when he wrote the poems in Le Spleen de Paris, a poetic prose "musical without rhythm or rhyme, supple enough and shocking enough to adapt itself to lyrical movements of the soul, undulations of the reverie, sudden leaps of conscience." Charles Simic believes prose poems contain a tension between the lyric impulse …

Public Policy: Affirmative Action, Social Equity, And Employment Patterns In Michigan's Construction Industry 1966-1997, Henry Joseph Bowers

Dissertations

Affirmative action public policy did not experience much debate when it was put in place during the late 1960’s. However, the debate is occurring in the 1990s. Its merits are being weighed and there are movements locally to eliminate affirmative action policy.

The Michigan construction industry is the focus of this study. This study examined not only these employment outcome benefits, but also outlines the outcome benefit trends over thirty-one years for national employment and employment in the state of Michigan with an emphasis on the construction industry. Details regarding white-collar and blue-collar occupational grouping trends as well as unemployment …

A single section of a mathematics course designed for elementary education majors that employed three different alternative assessments was the setting for the study.

A pre- and post-belief survey completed by students enrolled in the section under study represented the first level of data collection and analysis. The results of the pre-belief survey guided the selection of seven informants from the section and provided belief statements for the informants to verify during subsequent interviews. Based on the data …

Mitigating The Defects Of Pluralism: Interest Group Coalitions Before The Supreme Court, Jason Frederick Jagemann

Dissertations

This project examines interest group coalitional activity before the Supreme Court in affirmative action cases between 1971 and 1995. First, I address the characteristics and dynamics of amicus participants over time. Second, I examine the extent to which organizations with a smaller base of resources, in terms of staff and the number of years that organizations have been on the scene, engage in coalitional activity. I find that organizations with smaller staffs are more likely to participate in coalitions, and, contrary to my expectations, organizations that have been on the scene longer are more likely to engage in coalitional activity. …

Study Of Architecture And Protocols For Reliable Multicasting In Packet Switching Networks, Shiwen Chen

Dissertations

Group multicast protocols have been challenged to provide scalable solutions that meet the following requirements: (i) reliable delivery from different sources to all destinations within a multicast group; (ii) congestion control among multiple asynchronous sources. Although it is mainly a transport layer task, reliable group multicasting depends on routing architectures as well.

This dissertation covers issues of both network and transport layers. Two routing architectures, tree and ring, are surveyed with a comparative study of their routing costs and impact to upper layer performances. Correspondingly, two generic transport protocol models are established for performance study. The tree-based protocol is rate-based …

Time Domain Measurement Of The Nonlinear Refractive Index In Optical Fibers And Semiconductor Film, Hernando Garcia

Dissertations

A new technique to measure the nonlinear refractive index n₂ in optical fibers and semiconductor films has been developed. It is based on the time delay two-beam coupling of very intense picosecond laser pulses that have been self-phase modulated in the nonlinear optical medium. The two beams are coupled in a slow responding medium that is sensitive to time dependent phase distortions. We determine that the amount of phase distortion experienced by the pulse is proportional to the nonlinear refractive index of the medium, This time domain approach can also be applied to optical fiber amplifiers in the presence …

Genetically Evolved Dynamic Control For Quadruped Walking, Giorgio Grasso

Dissertations

The aim of this dissertation is to show that dynamic control of quadruped locomotion is achievable through the use of genetically evolved central pattern generators. This strategy is tested both in simulation and on a walking robot. The design of the walker has been chosen to be statically unstable, so that during motion less than three supporting feet may be in contact with the ground.

The control strategy adopted is capable of propelling the artificial walker at a forward locomotion speed of ~1.5 Km/h on rugged terrain and provides for stability of motion. The learning of walking, based on simulated …

Fluidization And Soot Filtration In A Rotating Fluidized Bed, Gui-Hua Qian

Dissertations

A horizontal rotating fluidized bed (RFB) has been investigated for the removal of soot from diesel engine exhaust. This requires necessitating an understanding of the nature of fluidization, particle mixing and filtration in the RFB.

In an RFB, particles are subject to a centrifugal force which can be much larger than the force of gravity. Therefore the Geldart classification for conventional fluidized beds must be modified for rotating fluidized beds. A theoretical analysis shows that group A particles (minimum bubbling velocity U_mb > minimum fluidization velocity U_mf can shift to group B U_mb = U_mf and group …

Simulation And Modeling Of Magnetically-Assisted Impaction Coating (Maic) Process For Dry Particle Coating, Bodhisattwa Chaudhuri

Dissertations

The objective of proposed research is to model, and understand the processes happening at multiple length and time scales in magnetically assisted impaction coating process. The smallest length scale is of the order of the molecular size and is important because during collisions the molecules rearrange themselves to form a semi-permanent bond between the core and secondary particles, which is studied by using the results of direct numerical integration of the governing Newton's equations. The effect of parameters such as size, orientation and relative velocity of particles on the collision mechanics is quantified. The largest length scale which is the …

A Study Of Droplet Burning In The Nearly Adiabatic Limit, Juan C. Gomez

Dissertations

We consider a small drop of liquid fuel that burns in an oxidizing gaseous environment and translates slowly (relative to flow 'at infinity') under the action of gravity. Practical applications include the burning of liquid fuels as sprays in domestic and industrial oil-fired burners, diesel engines, and liquid-propellant rocket motors. More relevant to the simple physical set-up of the present study are wellcharacterized laboratory experiments on the burning of a single, isolated fuel drop.

The drop burns in a nearly spherical, diffusion flame, flame sheet regime. We consider a specific example, or limit, referred to as 'nearly adiabatic burning', in …

Numerical Study Of Particle Dynamics In A Falling-Ball Viscometer, Peiwen Hou

Dissertations

The falling-ball viscometer is a device where a spherical particle falls along the axis of a circular cylinder filled with viscous fluid. The various classical results for this device are developed under the assumption that the Reynolds number of the flow is zero, i.e., Stoke's flow. Inertial effects are not taken into account. To better understand the dynamics of the particle sedimentation process and the role of inertia in this process, we implemented a numerical simulation.

The ADI (Alternating Direction Implicit) scheme is widely used to solve the vorticity-stream function formulation of the Navier-Stokes equation in axisymmetric geometries. However, a …
