Self-Organized Critical & Complex Adaptive Systems In A Simulated Manufacturing Environment, Kaine Gill

Theses

The application of this thesis compares three different manufacturing theories, varying on resource allocation, to decide which performs best. Three Resource Allocation methods are analyzed including a static resource allocation method, a semidynamic resource allocation method, and a dynamic resource allocation method. The last methodology used in this thesis develops a resource allocation method intended to display complex behavior. A Base Case manufacturing simulation is developed to represent a static resource allocation system. A Theory of Constraints manufacturing model using the Theory of Constraints process represents a semi-dynamic resource allocation system. A Complex Adaptive System manufacturing model using autonomous agents …

Living In A House Of Cards: Family Experiences With Long-Term Childhood Technology Dependence, Maureen O'Brien

College of Nursing Faculty Research and Publications

Families' experiences of providing long-term home care for the child who is technology dependent were explored via parental interviews. Families identified frequent change, uncertainty, and unpredictability in their lives, a phenomenon described as "living in a house of cards." Attempts to increase stability involved the use of vigilance, advocacy, and reframing. Areas of challenge, change, and growth included making sense of life, managing daily life with technology, and maintaining a functioning family. Increased understanding of family experiences with long-term childhood technology dependence can provide nurses with additional strategies for providing optimal care to this population.

Comparison Of Optical Density, Total Cell Protein, And Number Of Viable Cells (Via Fluorescent Straining) As Measures Of Microbial Growth Kinetics In Suspended And Biofilm Cultures During Biodegradation Of Naphthalene, Jeong Seop Shim

Dissertations

Most studies on bacterial growth kinetics have been dependent on theoretical modeling with general biomass measurements using either dry weight or optical density (OD), without distinguishing live from dead bacteria or debris. As a result, there remains considerable uncertainty in reliably predicting rates of biodegradation for design of treatment processes for environmental pollutants.

This research focused on measurement of bacterial growth rates and activities in suspended cultures and biofilms using Pseudomonas putida (ATCC 17484) for biodegradation of naphthalene. As expected, the rates of biodegradation differed between suspended and immobilized cultures. A comparison was made of the impact of three biomass …

Numerical Modeling And Optimization Of Waterjet Based Surface Decontamination, Konstantin Babets

Dissertations

The mission of this study is to investigate the high-pressure waterjet based surface decontamination. Our specific objective is to develop a practical procedure for selection of process conditions at given constraints and available knowledge. This investigation is expected to improve information processing in the course of material decontamination and assist in the implementation of the waterjet decontamination technology into practice. The development of a realistic procedure for processing of a chaotic and non-accurate information constitutes the main accomplishment of this study.

The research involved acquisition of representative information about removal of brittle, elastic and viscous deposits. As a result an …

Environmental Science In The New Millennium : A Model To Give Structure And Guidance, James M. Lipuma

Dissertations

This work proposes a template for successful interdisciplinary Environmental Science (EVSQ) programs at four-year American learning institutions. The first conclusion reached is that there is no one "perfect" program. Only by identifying clear goals for EVSC can programs improve. It was determined that a clear definition of EVSC and mission statements related to these definitions are necessary first steps to allow improvement to occur. One major outcome of the work is the educational model built to understand EVSC education. The model identifies methods by which the goals and objectives of EVSC can be identified and accomplished. The research found that …

Analysis Of Discrete Dynamical System Models For Competing Species, Jerry J. Chen

Dissertations

A discrete version of the Lotka-Volterra (LV) differential equations for competing population species is analyzed in detail, much the same way as the discrete form of the logistic equation has been investigated as a source of bifurcation phenomena and chaotic dynamics. Another related system, namely, the Exponentially Self Regulating (ESR) population model, is also thoroughly analyzed. It is found that in addition to logistic dynamics - ranging from the very simple to manifestly chaotic regimes in terms of the governing parameters - the discrete LV model and the ESR model exhibit their own brands of bifurcation and chaos that are …

Development And Application Of A Computer Simulation Tool For Ecological Risk Assessments, Haiyi Lu

Theses

In an effort to improve tools in ecological risk assessment (ERA), an ERA software tool was developed and applied. Based on a preliminary evaluation of existing ecorisk models, the relative deficiencies were identified and included the need for a user-friendly interface, an interactive database management system (DBMS), and a comprehensive evaluation of exposure pathways. In this research, Visual Basic (VB) 6.0 and Microsoft SQL server were selected for developing the Windows-based interface and local DBMS, respectively. For the exposure estimate, Yuma and Aberdeen Proving Grounds were identified as baseline ecosystems. Terrestrial and aquatic plant and animal receptor selection was based …

Variations In Bacterial Community Structure During A Dinoflagellate Bloom Analyzed By Dgge And 16s Rdna Sequencing, Laura B. Fandino, Lasse Riemann, Grieg F. Steward, Richard A. Long, Farooq Azam

Faculty Publications

The relationship between bacterial 16S rRNA gene composition and carbon metabolism was analyzed during an intense dinoflagellate bloom off the Southern California coast during the spring of 1997. Bacterial numbers and rate processes, chlorophyll a, and the dissolved and particulate organic matter pools were measured during the bloom to provide a framework within which to assess bacterial community composition. Free bacteria were numerically dominant, generally comprising >90% of the total, and were responsible for >70% of bacterial production. Attached bacteria had higher cell-specific growth rates than free bacteria (range = 0.5 to 15.1 and 0.7 to 2.5 d^{-1 …}

Optimization Of Nitrogen Removal In Sequencing Batch Reactor, Suppakit Poonyachat

Theses

Operating parameters for sequencing batch reactor have the influenceon each substrate concentration. Concentration profile changes as operationparameters are changed. The study was conducted to model the variationin effluent concentration from sequencing batch reactor. MLVSS and cycletime are the parameters that were varied. Concentration in Fill, React,and Settle Period were calculated by using kinetic equations.

The results can show that these parameters have effects on the concentrationprofile. The increase of MLVSS can lower the concentration of BOD andammonium concentration in React period. Increasing MLVSS can show thatmore substrate utilization and nitrification process occur more rapidly.Concentration of nitrate at the end of …

Physical as well as mental effects were discussed to develop a basis for the physiological adaptations due to cold stress. The study focused on workers that performed various simple and complex tasks in a refrigerated warehouse with a temperature range 32° - 40°F. Surveys were distributed to employees who presently and previously worked in this refrigerated area. The "Picker" and "Feeder" tasks were analyzed as they pertain to this low …

Testing Of Semiconductor-Based Adsorption Modified Photosensitive (Samp) Sensor For Response To Toluene, Ashish Agrawal

Theses

The response of semiconductor-based adsorption modified photosensitive sensor is based on the dye-enhanced photoconductivity of a CdS semiconducting film. The change in this photoconductivity is brought about when organic molecules are sorbed onto the dye-coated surface. The response is related to the overlap in the infrared spectrum of the dye with that of the analyte.

This research was carried out to study the response of the sensor to a typical hydrocarbon, toluene. The sensor was tested for its response to concentrations of toluene ranging from 2.6 ppm to 200 PPM in nitrogen. The sensor was tested under non-flow conditions and …

An Examination Of Discourse Concerned With Pcb Remediation In The Hudson River, Jennifer M. Coffey

Theses

Remediation of PCB contamination in the Hudson River is an issue hotly contested within local communities, the media, and between government agencies and corporate entities. In recent years, the EPA has decided to revisit their 1984 no-action decision for the Hudson River and in December 2000, issued a Feasibility Study recommending partial dredging of the 200 miles of the Hudson floor deemed a Superfund site. The EPA's reevaluation of their 1984 decision has spurred an enormous amount of literature from corporate, non-profit volunteer, and government agencies.

The rhetorical theory of social constructionism and the ethical theory of environmental pragmatism are …
