Beyond Topography: Remapping Appalachia
… are inadvertently working with mountains and topography, this thesis proposes a design methodology for architectural operations through these geologic scales of place and time. With media as method, this exploratory research presents a range of approaches to telling the story of resource …

Flow over finite isolated topography
… used to study flow over axisymmetric isolated topography. Inviscid or nearly inviscid flow in which non-linear effects have order one importance is considered, and both the effects of β and finite topography are included. A one-layer quasi-geostrophic model is used to find the shape of Taylor …

Continental Magmatism and Dynamic Topography
… first two processes are well understood, dynamic topography remains controversial. On the continents, dynamic uplift is often expressed by positive long-wavelength gravity anomalies, radial drainage patterns, and slow seismic velocity anomalies within the upper mantle. Volcanic activity and …

Air pollution modelling over complex topography
… deals with air pollution modelling over complex topography, both from the phenomenological and numerical point of view. The theme of air pollution modelling has been faced at first from a phenomenological point of view. Then a numerical approach for the resolution of the diffusion-advection …

Free surface flow over bottom topography
… thesis explores flow in a channel over a bottom topography. In particular, the problem of finding the shape of the unknown free-surface if the bottom topography is prescribed forms the main problem of this thesis. In chapter 2 the forced Korteweg De- Vries equation is derived from first …

Modelling dry granular flows over topography
… and temporal inhomogeneities collectively as topography. In this thesis, we apply a common rheological model to problems involving various types of spatial or temporal topography. One problem that we shall particularly study concerns a flow down a chute that experiences a sudden increase in …

Quantifying turbidity current interactions with topography
… are mediated by interactions with seafloor topography, specifically channelized surfaces. Turbidity currents are responsible for crafting the morphology of continental margins. Unfortunately, very few direct observations exists defining turbidity current interactions with submarine channels …

When an eddy encounters shelf-slope topography
… must then interact with continental shelf-slope topography at the western boundary. The presence of other eddies and mean lows complicates this simple picture, yet satellite images show that mesoscale eddies translating near the shelfbreak routinely affect the continental shelves of the …

Fractal analysis of topography and reflectance surfaces
The definition of a fractal has been successfully deduced from constructing the Koch curve and the Cantor set. Principles of seven methods (the ruler, box-counting, spectral structure function, intersection methods, cube-counting, and triangular prism methods) for determining the fractal dimensions …

Measuring Corneal Topography Using Wavefront Analysis Technique
… Available techniques for measuring corneal topography include keratometry, videokeratoscopy, and scanning slit imaging. A new type of instrument, a corneal topographer based on a Hartmann-Shack wavefront sensor for measuring corneal elevation over a spherical surface, is presented in this …

The measurement and characterization of surface topography
The concept of surface topography is introduced and its relevance to the production and functional behaviour of engineering components is highlighted. Some aspects of the measurement and characterization of surface topography are reviewed. The strengths and weaknesses of particular techniques are …

Le Bel Inconnu: A Semiotic Topography (France)
This study is a Greimasian semiotic reading of the twelfth-century French romance. The analysis describes the syntactic structure of the text in terms of narrative programs and narrative progression, actantial arrangement and duplications and manipulation as a narrative technique. The semantic …

Dynamic Topography of Madagascar and its Surroundings
Some portion of long-wavelength topography and bathymetry in the southwestern Indian Ocean is supported by convective processes within the Earth's mantle. Predictive models suggest that both southern Africa and the southwestern Indian Ocean are anomalously elevated by 0.5--1.5~km. In contrast, …

Evolution of topography in glaciated mountain ranges
… drainage basins at the expense of low-relieftopography. Glaciers have lowered valley floors and ridgelines by similar amounts, limiting the amount of "missing mass" that can be generated, and causing a decrease in drainage basin relief.

Linear and nonlinear stratified spindown over sloping topography
… couple with the buoyancy field over sloping topography. Analytical and numerical methods are used to quantify the impact of this coupling on the vertical circulation, spindown of geostrophic flows, and the formation of a shelfbreak jet. Over a stratified slope, linear spindown of a …
