A Competitive Reconfiguration Approach To Autonomous Fault Handling Using Genetic Algorithms, Kening Zhang Jan 2008

A Competitive Reconfiguration Approach To Autonomous Fault Handling Using Genetic Algorithms, Kening Zhang

Electronic Theses and Dissertations

In this dissertation, a novel self-repair approach based on Consensus Based Evaluation (CBE) for autonomous repair of SRAM-based Field Programmable Gate Arrays (FPGAs) is developed, evaluated, and refined. An initial population of functionally identical (same input-output behavior), yet physically distinct (alternative design or place-and-route realization) FPGA configurations is produced at design time. During run-time, the CBE approach ranks these alternative configurations after evaluating their discrepancy relative to the consensus formed by the population. Through runtime competition, faults in the logical resources become occluded from the visibility of subsequent FPGA operations. Meanwhile, offspring formed through crossover and mutation of faulty and …

Nutrient Removal From Stormwater By Using Green Sorption Media, Fahim Hossain Jan 2008

Nutrient Removal From Stormwater By Using Green Sorption Media, Fahim Hossain

Electronic Theses and Dissertations

High nitrogen and phosphorus content in storm water runoff has affected groundwater, springs and surface water by impacting ecosystem integrity and human health. Nitrate may be toxic and can cause human health problem such as methemoglobinemia, liver damage and even cancers. Phosphorus may trigger the eutrophication issues in fresh water bodies, which could result in toxic algae and eventually endanger the source of drinking waters. Sorption media with mixes of some recycled materials, such as sawdust and tire crumb, combined with sand/silt and limestone, becomes appealing for nutrient removal in environmental management. This paper presented is a specific type of …

Performance Based Decision System In Determining Post Closure Care (Pcc) Duration In Florida Landfills, Asawari Kulkarni Jan 2008

Performance Based Decision System In Determining Post Closure Care (Pcc) Duration In Florida Landfills, Asawari Kulkarni

Electronic Theses and Dissertations

This study is an evaluation of Post Closure Care (PCC) duration of landfills using performance based methodology. The post closure care phase begins once the landfill is closed. As required by the Resource Conservation Recovery Act (RCRA) Subtitle D, PCC duration for municipal solid waste landfills is 30 years. During the PCC period, the landfill operator/owner is required to conduct monitoring for leachate, landfill gas, and ground-water and maintain the integrity of the cap so that the landfill does not impose a threat to surrounding human health and environment (HH&E). The duration of PCC can be reduced by the director …

A Hybrid System Dynamics-Discrete Event Simulationapproach To Simulating The Manufacturing Enterprise, Magdy Helal Jan 2008

A Hybrid System Dynamics-Discrete Event Simulationapproach To Simulating The Manufacturing Enterprise, Magdy Helal

Electronic Theses and Dissertations

With the advances in the information and computing technologies, the ways the manufacturing enterprise systems are being managed are changing. More integration and adoption of the system perspective push further towards a more flattened enterprise. This, in addition to the varying levels of aggregation and details and the presence of the continuous and discrete types of behavior, created serious challenges for the use of the existing simulation tools for simulating the modern manufacturing enterprise system. The commonly used discrete event simulation (DES) techniques face difficulties in modeling such integrated systems due to increased model complexity, the lack of data at …

A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson Jan 2008

A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson

Electronic Theses and Dissertations

In recent years the nutrient levels of the Upper Floridan aquifer have been increasing (USGS, 2008). An example of this is found in Ocala, Florida where Silver Springs nitrate concentrations have risen from 0.5 mg/L in the 1960 s to approximately 1.0 mg/L in 2003 (Phelps, 2004). Because stormwater is a contributor to surficial and groundwater aquifer recharge, there is an increasing need for methods that decrease nitrogen and phosphorus levels. A laboratory column study was conducted to simulate a retention pond with saturated soil conditions. The objectives of the column studies reported in this thesis were to investigate the …

Probing And Tuning The Size, Morphology, Chemistry And Structure Of Nanoscale Cerium Oxide, Satyanarayana Kuchibhatla Jan 2008

Probing And Tuning The Size, Morphology, Chemistry And Structure Of Nanoscale Cerium Oxide, Satyanarayana Kuchibhatla

Electronic Theses and Dissertations

Cerium oxide (ceria)-based materials in the nanoscale regime are of significant fundamental and technological interest. Nanoceria in pure and doped forms has current and potential use in solid oxide fuel cells, catalysis, UV- screening, chemical mechanical planarization, oxygen sensors, and bio-medical applications. The characteristic feature of Ce to switch between the +3 and + 4 oxidation states renders oxygen buffering capability to ceria. The ease of this transformation was expected to be enhanced in the nanoceria. In most the practical scenarios, it is necessary to have a stable suspension of ceria nanoparticles (CNPs) over longer periods of time. However, the …

Interaction Of The Legitimate System And The Shadow System In Organisations, Caroline Halpin, Philomena Hanlon Jan 2008

Interaction Of The Legitimate System And The Shadow System In Organisations, Caroline Halpin, Philomena Hanlon

Conference papers

This research examines the relationship between the Legitimate and the Shadow Systems in organisations: an interaction that can result in bringing an organisation into a state of bounded instability, and therefore increased creativity and innovation. The Legitimate System consists of the formal hierarchy, bureaucracy, rules, controls and communication patterns in an organisation. A properly functioning Legitimate System is vital for the conduct of business in an organisation in order to ensure its survival and efficiency. The Shadow System is a term coined by Stacey (1997) to describe the informal network of relations within the organisations that are evident in casual …

The Misuse Of Terrorism Prosecution In Chile: The Need For Discrete Consideration Of Minority And Indigenous Group Treatment In Rule Of Law Analyses, Noah Bialostozky

Northwestern Journal of Human Rights

The Mapuche of South America have long struggled to maintain control over their ancestral lands, territory that now falls under the sovereign domain of Argentina and Chile. Since Chilean independence in the 19th century, the relationship between the Mapuche and the Chilean government has ranged between full-blown conflict and various forms of compromise and accommodation. However, over the past few decades, the Chilean government's economic interests in Mapuche lands have grown significantly and the government has seized control of significant portions of the lands. The Mapuche have consistently resisted the government's encroachment on their lands and have protested through both …
