Simulation Of Imaging Fourier Transform Spectrometers Using Dirsig, Francois Alain

Theses

Imaging Fourier Transform Spectrometers are becoming popular sensors for hyperspectral re mote sensing. To evaluate sensor design artifacts and properties, it is useful to simulate their designs using a radiometrically correct ray-tracing tool. The Digital Imaging and Remote Sensing Image Generation model allows for such design and simulation of sensor properties. Two different design types are evaluated and simulated. The first one is a Michelson-type interferometer. The sensor collects the image by operating in "stare mode" The interferogram is collected over time by scanning one of the mirrors to generate the required optical path difference between the signals. The second …

"To Make The Crooked Ways Straight And The Rough Ways Smooth": The Federal Government's Role In Laying Out And Building The Cumberland Road., Billy Joe Peyton

Graduate Theses, Dissertations, and Problem Reports (ETD)

By 1800 the United States had emerged from the turmoil of its Revolutionary era to begin focusing on economic growth and westward expansion. To open up the vast trans-Appalachian region the federal government in 1802 began formulating plans to fund and build a "national road to connect the eastern seaboard with the "western waters. After considerable debate, Congress in 1806 passed an act that called for laying out and making a road from the Potomac River at Cumberland, Maryland, to the Ohio River at Wheeling, (West) Virginia. A six-member surveying team led by three presidentially-appointed commissioners completed the arduous task …

Development Of And Measurement Using A Point Doppler Velocimetry (Pdv) System., David L. Webb

Graduate Theses, Dissertations, and Problem Reports (ETD)

A two component Point Doppler Velocimetry (PDV) system has been developed and tested. Improvements were made to an earlier PDV system, in terms of experimental techniques, as well as the data acquisition and reduction software. Measurements of the streamwise and spanwise mean and fluctuating velocities for flows from a rectangular channel and over an NACA 0012 airfoil were made, and the data were compared against hot wire data. The closest to the airfoil surface that PDV measurements could be made was on the order of 0.005 m (0.2”, z/c = 0.0169). When the PDV and hot wire data were compared, …

The Development Of A Droplet Formation And Entrainment Model For Simulations Of Immiscible Liquid-Liquid Flows., Wesley Michael Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Droplet formation is a common phenomenon in turbulent mixing and has many practical applications in emulsion technology, surface agents, and liquid-liquid extraction. The ability to predict the relative sizes and distributions of fluid droplets formed from mixing events is a complex problem which is dependent on many different parameters including geometric considerations, the nature and physical properties of the fluids in question, turbulence parameters, buoyancy and body forces, and flow history. While there have been many researchers who have analyzed this problem for both liquid-liquid and gasliquid systems, the present study will focus only on droplet formation in immiscible liquid-liquid …

The Measurement And Characterisation Of Aerosol In The Urban Atmosphere (Pm10) And An Evaluation Ofthe Sources Of These Particles By Number, Andrew Lindsay Dye

School of Geography, Earth and Environmental Sciences Theses

The link between human health and the mass of fine particulate matter below 10 µm(PM10) in air is well documented. Current research suggests that the number, size and shape of particles may be of most concern and that in the urban atmosphere combustion sources of PM10, especially diesel engine sources, dominate the line (< 1 µm) and ultra-fine ( <0.1 µm) particles. Despite this, the number, size and shape of particles in urban air has not been reported to any great extent or detail, and the percentage contribution to the numbers of particles from different sources is largely unknown. The objectives of this research were to characterise fine particles with respect to their morphology and thus apportion the sources of particles by number. Urban aerosol above 1 µm was initially examined to study the fluctuations in PM10 number and make retrospective analysis of periods of elevated PM10 for source identification in Plymouth, UK. Aerosol was collected via a Burkard spore trap and examined using light microscopy with image analysis between 16 March 1995 and 31 August 1996, at a background site in Plymouth, UK. Two periods, 19 January-4 February and 10-25 March 1996, identified as UK wide PM10 episodes, were retrospectively studied and compared with PM10 mass measurements. The mean number count for the whole period was 10.5 x 104 ± 7.9 x 104 particles m ˉ³ The two PM10 episodes had elevated average number concentrations of 13.5 x 104 ±7.6 x 104 particles m ˉ³ for 19 January- 4 February 1996, and 13.0 x 104 ± 9.7 x 104 particles m ˉ³ for 10-25 March 1996. During the periods of elevated PM10 the tapered element oscillating microbalance (TEOM) mass of panicles had a low correlation with the particles less than 5 µm and an increased correlation to the particles greater than 5 µm in size. Outside of these peak periods the PM10 TEOM mass was most closely correlated with the number of particles less than 5 µm in size. This work shows the difference in urban aerosol during periods of air quality guideline exceedence. These findings agree with literature that an aged continental aerosol source has a key role in the generation of UK wide PM10 mass exceedances. Further analysis of the line urban aerosol (< 1 µm) was made using direct sampling of urban aerosol on to porous carbon films (PCF) developed in this research. The efficiency of collection was low (ea. 5%) but the samples were representative and enabled transmission electron microscopy (TEM) for sub-micron particle analysis. Measurement was made of the fractal dimensions and diameter of particles. This was used to identify any ageing and ultimately the sources of aerosol. PCF were used in the simultaneous collection of urban roadside and background aerosol, on seven dates between December 1996 and August 1997 in Plymouth, UK. The average perimeter fractal dimension (PFD) of aerosol was consistently significantly greater at the roadside than the background (+ 0.02), indicative of a smoother, aged aerosol at the background site. The sampling of a variety of combustion engines was made for source identification purposes. The particle morphology produced from the diesel engines showed great uniformity of particle morphology with varying speed and load; no consistent significant differences were found. The morphology results were comparable to other density fractal dimensions and perimeter fractal dimension values found in other studies for diesel. A natural log relationship between the median particle size and the median PFD was found for the diesel engine sources but not in petrol samples. This natural log trend was considered as a tentative 'fingerprint' of diesel engine combustion and was in harmony with literature values of PFD for diesel engine particles. Using the fractal measures, size and particle classification the bulk of aerosol was identified as from hydrocarbon combustion sources; ea. 88-92% of the roadside and ea. 77-86% of background. A component of carbon ceno-spheres were identified contributing ea. 6-12% of both the roadside and background aerosol. Non-combustion particles increased from ea. 1-4% of the roadside to ea. 7-9% of the background, as did the proportion of aged combustion particles, from 0-1% of roadside to 2-3% of the background aerosol. A strong correlation for the median size vs. PFD morphology curve between, the roadside and diesel sources (0.93 - 0.95) and the background and petrol sources was found (0.95). The roadside aerosol was significantly different to the petrol source in the l20-220nm size range (p=0.007) and there was a low correlation of the petrol and the roadside size vs. morphology curve (0.66). This suggests the domination of

Antimony Speciation By Chromatographic Sample Introduction To Plasma Spectroscopy, Alen Bruce Guy

School of Geography, Earth and Environmental Sciences Theses

Antimony (Sb), an element in Group V of the Periodic Table, has an ancient and varied chemistry with many applications in industry and medicine. However, although sensitive analytical methods exist for the determination of Sb very tittle is known about the speciation of the element. It is widely known that the toxicity of Sb is not only dependent upon its oxidation state but also its molecular form. Thus this study has utilised chromatographic sample introduction directly coupled to plasma spectroscopic instruments to facilitate separations of Sb based upon molecular form coupled with sensitive detection methods. Fundamental studies, using NMR to …

Void Structure, Colloid And Tracer Transport Properties Of Stratified Porous Media, Tobias John Mathews

School of Geography, Earth and Environmental Sciences Theses

The characterisation of the properties of porous materials is of great importance in the effective management of natural and manmade systems. A sophisticated network model, 'Pore-Cor', of some of these properties has been previously developed. The present study has significantly extended the scope of the model's predictive capabilities. Flow and transport behaviour was examined in laboratory sand columns of various depths. These experiments examined unsaturated flow of water and conservative solute tracer transport through homogeneous sand samples. Flow through these was not homogeneous or repeatable. Experimental observations found that this may have been due to subtle random variations in packing, …

Privatising Britain's Passenger Railway : Expectations And Outcomes Of The 'Free' Market Approach, Jon Shaw

School of Geography, Earth and Environmental Sciences Theses

The privatisation of the British railway industry was announced in 1992, and a central plank of the government's strategy was to liberalise British Rail's (BR's) passenger market at the time of its divestiture. Competition was to be introduced both for the market, through franchising, and in the market, by freeing up access to the rail network. This thesis examines the policy adopted to promote competition in the British passenger railway industry. Its central aim is to assess the extent to which the promotion of competition between passenger train operators was an appropriate policy goal. In pursuit of this aim, the …

Soil Moisture Variability: Implications For The Hydrology, Erosion And Management Of Gullied Catchments In Central Spain, Christopher Fitzjohn

School of Geography, Earth and Environmental Sciences Theses

In semi-arid environments, the combination of a non-uniform distribution of vegetation, an often highly irregular terrain and complex geological, pedological and management histories have frequently given rise to considerable spatial variability in the physical and hydrological properties of soils. Heterogeneity within the soil's physical and hydrological properties can result in pronounced differences in infiltration and soil moisture. The hydrological response of semi-arid landscapes to rainfall events may therefore be spatially non-uniform. Quantifying the spatial pattern of hydrological response is important for identifying those areas within the landscape which arc vulnerable to runoff and erosion. Since soil moisture is considered to …

Ichthyophthirius Multifiliis Fouquet: Development And Assessment Of In Vitro Systems For Long Term Maintenance, Louise Margaret Hurley

School of Biological and Marine Sciences Theses

Twelve isolates of lchthyophthirius multifiliis were successfully established and maintained by serial passage through naive carp, for a maximum of 39 laboratory cycles. The management system employed was such that large numbers of the parasite were available for all investigations. The ability to induce exit of immature trophonts through media incubation was used to confirm events in the initial stages of host colonisation. The normal course of primary infection was also established providing useful criteria for assessing success of the in vitro systems tested. Survival of both theronts and tomonts within selected monophasic media was investigated. Theronts in Eagles Minimum …

Thermal Characterization Of Pmma Thin Films On Silica Using Modulated Differential Scanning Calorimetry, Crystal E. Porter, Frank D. Blum

Chemistry Faculty Research & Creative Works

The number of studies of thin polymer films has increased over recent years as technological processes incorporate the use of nanomaterials. An enhanced understanding of these films would enable us to predict bound-polymer behavior and thus improve the efficiency of processes and the quality of products. This is especially true as the thickness of the films approach molecular dimensions. The glass transition temperature of a polymer is one of the most important properties for characterization because it indicates how the polymer might perform macroscopically. when a polymer is confined, such as one the surface of a substrate, its behavior is …

Dynamics Of Acrylic Coupling Agents At Interfaces Of Composites, Hyoryoon Jo, Frank D. Blum

Chemistry Faculty Research & Creative Works

Most applications of polymers involve composites, wherein a polymer is used in conjunction with another material, typically a solid fiber or filler. A coupling agent can enhance the adhesion between a polymer matrix and an inorganic filler. Organofunctional silanes, RSiX are often used as coupling agents. The methoxy or ethoxy group, X, can typically be hydrolyzed with water and an acid or a base catalyst in a protic solvent. The silanol groups of a hydrolyzed coupling agent can condense with other silanol groups from a glass surface, while the alkyl group, R, blends physically or bonds chemically to the polymer …
