Dimesionality Aspects Of Nano Micro Integrated Metal Oxide Based Early Stage Leak Detection Room Temperature Hydrogen Sensor, Sameer Arun Deshpande

Electronic Theses and Dissertations

Detection of explosive gas leaks such as hydrogen (H2) becomes key element in the wake of counter-terrorism threats, introduction of hydrogen powered vehicles and use of hydrogen as a fuel for space explorations. In recent years, a significant interest has developed on metal oxide nanostructured sensors for the detection of hydrogen gas. Gas sensors properties such as sensitivity, selectivity and response time can be enhanced by tailoring the size, the shape, the structure and the surface of the nanostructures. Sensor properties (sensitivity, selectivity and response time) are largely modulated by operating temperature of the device. Issues like instability of nanostructures …

Optimizing The High Dynamic Range Imaging Pipeline, Ahmet Oguz Akyuz

Electronic Theses and Dissertations

High dynamic range (HDR) imaging is a rapidly growing field in computer graphics and image processing. It allows capture, storage, processing, and display of photographic information within a scene-referred framework. The HDR imaging pipeline consists of the major steps an HDR image is expected to go through from capture to display. It involves various techniques to create HDR images, pixel encodings and file formats for storage, tone mapping for display on conventional display devices and direct display on HDR capable screens. Each of these stages have important open problems, which need to be addressed for a smoother transition to an …

Signal Processing Of An Ecg Signal In The Presence Of A Strong Static Magnetic Field, Aditya Gupta

Electronic Theses and Dissertations

This dissertation addresses the problem of elevation of the T wave of an electrocardiogram (ECG) signal in the magnetic resonance imaging (MRI). In the MRI, due to the strong static magnetic field the interaction of the blood flow with this strong magnetic field induces a voltage in the body. This voltage appears as a superimposition at the locus of the T wave of the ECG signal. This looses important information required by the doctors to interpret the ST segment of the ECG and detect diseases such as myocardial infarction. This dissertation aims at finding a solution to the problem of …

Fate Of Nitrogen And Phosphorus Species From A Black And Goldtm Nugget Mix In A Laboratoy Column Simulated Septic Tank Drainfiel, Timir Shah

Electronic Theses and Dissertations

The presence of nitrates and phosphorus in ground water is a worldwide problem. A septic tank with drainfield that is conventionally designed does not typically remove nitrogen in the form of nitrates. The main risks are in "Blue baby" syndrome and suspected carcinogenic effect of nitrates on humans and the nutrient enrichment of receiving waters. In some areas nitrate and phosphorus removal are essentially required. Thus the information in this report concentrates on using media in the drainfield for the removal of nitrogen and phosphorus. Extensive work has been conducted in the past few decades in order to find suitable …

An Economic Framework For Resource Management And Pricing In Wireless Networks With Competitive Service Providers, Shamik Sengupta

Electronic Theses and Dissertations

A paradigm shift from static spectrum allocation to dynamic spectrum access (DSA) is becoming a reality due to the recent advances in cognitive radio, wide band spectrum sensing, and network aware real--time spectrum access. It is believed that DSA will allow wireless service providers (WSPs) the opportunity to dynamically access spectrum bands as and when they need it. Moreover, due to the presence of multiple WSPs in a region, it is anticipated that dynamic service pricing would be offered that will allow the end-users to move from long-term service contracts to more flexible short-term service models. In this research, we …

Behavior Of Variable-Length Genetic Algorithms Under Random Selection, Harold Stringer

Electronic Theses and Dissertations

In this work, we show how a variable-length genetic algorithm naturally evolves populations whose mean chromosome length grows shorter over time. A reduction in chromosome length occurs when selection is absent from the GA. Specifically, we divide the mating space into five distinct areas and provide a probabilistic and empirical analysis of the ability of matings in each area to produce children whose size is shorter than the parent generation's average size. Diversity of size within a GA's population is shown to be a necessary condition for a reduction in mean chromosome length to take place. We show how a …

Biostability In Drinking Water Distribution Systems In A Changing Water Quality Environment Using Corrosion Inhibitors, Bingjie Zhao

Electronic Theses and Dissertations

In this study, the bacterial growth dynamics of 14 pilot drinking water distribution systems were studied in order to observe water quality changes due to corrosion inhibitor addition. Empirical models were developed to quantity the effect of inhibitor type and dose on bacterial growth (biofilm and bulk water). Water and pipe coupon samples were taken and examined during the experiments. The coupons were exposed to drinking water at approximately 20°C for at least 5 weeks to allow the formation of a measurable quasi- steady-state biofilm. Bulk water samples were taken every week. In this study, two simple but practical empirical …

Regulating Human Tissue Banks, Laura A. Buck

St. Thomas Law Review

This paper will give a general overview of the tissue bank industry from its beginnings to the present day. It will address the regulations promulgated by the FDA, laws enacted by states, and the guidance provided by the American Association of Tissue Banks. Finally, it will discuss and suggest further regulations and standards that are needed as the industry grows.

Heylen Bvba (Belgium), Thomas Cooney

Case studies

As Tom Heylen reflects upon his early days in business, he often wonders how his company Heylen bvba survived. He had left university after just one year of studying biology in order to pursue a business opportunity that he believed existed in the market and that needed to be acted upon without delay. About that time, nature had become modified to such an extent (particularly in Europe) that biodiversity could only be conserved through active management and restoration of the few natural areas which remained. Such management required innovation, specialised equipment, and knowledge in order to be successful. But those …

Ecoserve (Ireland), Thomas Cooney

Case studies

Roisin Nash had just finished reading a new report that had recently been launched by the Minister for Communications, Marine and Natural Resources Noel Dempsey at the headquarters of the Marine Institute at Oranmore in County Galway. The report, entitled ‘Sea Change – A Marine Knowledge, Research and Innovation Strategy for Ireland 2007- 2013’, presented a national agenda (comprising of science, research, innovation, and management) aimed at a complete transformation of the Irish maritime economy. Roisin felt that the report provided a clear and realistic picture of future opportunities and challenges within the Irish marine industry, and that it would …

Echinades Fish Farm (Greece), Thomas Cooney

Case studies

The past decade had seen a dramatic decline in the regional economy along the west coast of the Greece as agriculture faded and few incentives existed for manufacturing companies to locate there given its relatively poor infrastructure. Since the long-established Greek strength of tourism was still focused on the islands and in areas where large natural beaches offered holidaymakers the opportunity to lay out in the glorious Mediterranean sunshine, this region of barren land and traditional lifestyle offered little to entice the modern tourist. Despite this pessimistic background, Nikos Anagnopoulos stood on the deck of the small boat that had …
