Alternative Sustainable Design within an Established StructureCooney, Katie 08 May 2015 (has links)
Sustainable Built Environments Senior Capstone / This thesis seeks to develop an alternative sustainable design for the CareLink of Jackson medical facility. Through a thorough analysis of the structure, community, environment, and user interaction within and around the building, a complete understanding of the facility's needs, successes and failures were composed. Based on this analysis, an alternative design was then proposed of which incorporates improvements to the building's green space, solar utilization, and social integration. This final design analysis and recommendation can be used to inform similar redevelopment of established structures in the benefits of sustainable integration within architecture.

The Cretaceous - Tertiary Tectonic Evolution of the Lhasa terrane, TibetVolkmer, John E. January 2010 (has links)
A thorough understanding of Tibetan Plateau growth requires knowledge of the geological evolution of the Tibetan terranes as they were accreted to the Eurasian margin during the Phanerozoic. This dissertation research addresses the tectonic evolution of the southernmost of these, the Lhasa terrane of Tibet from the Late Jurassic to Eocene. The data and insights presented herein are the result of extensive geologic fieldwork in the northern and central Lhasa terrane of Tibet. In this work I present new geologic mapping and thermochronologic data that reveals a terrane scale passive roof thrust belt in the northern Lhasa terrane that accommodates significant upper crustal shortening without exhuming basement rocks. Through the development of a geospatially referenced database of igneous crystallization ages, I show that Cretaceous magmatism on the Lhasa terrane was not static, but exhibited significant temporal-spatial migrations. I interpret these movements as the result of variations in Neo-Tethyan slab dip and suggest that these variations are a major factor in shaping the Cretaceous tectonics of the Lhasa terrane. Finally, I present the Cretaceous-Eocene tectonic evolution of the Lhasa terrane that shows that the Lhasa terrane was above sea level and likely had attained significant elevation prior to the accretion of India to Eurasia and that the development of the high elevation Plateau developed outward from a central core, rather than from south to north as is commonly thought. These insights refute the widely held view that the Tibetan Plateau is the result of the Cenozoic Indo-Asian collision.

Videogrammetric roof surveying using a hybrid structure from motion approachFathi, Habib 12 January 2015 (has links)
In a roofing project, acquiring the underlying as-built 3D geometry and visualizing the roof structure is needed in different phases of the project life-cycle. Architectural drawings, building information model (BIM) files, or aerial photogrammetry are used to estimate the roofing area in the bidding process. However, as a roof structure is never built to the exact drawing dimensions, as-built dimensions of boundaries of every roof plane have to be obtained several times during the course of its build. There are a number of surveying methods that can be used for this purpose: tape measuring, total station surveying, aerial photogrammetry, and laser scanning. However, obtaining measurements using these methods could be costly in terms of equipment, labor, and/or worker exposure to safety hazards. Aiming to address this limitation and provide roofing practitioners with an alternative roof surveying and visualization method that is simple to use, automated, inexpensive, and safe, a close-range videogrammetric roof 3D reconstruction framework is presented in this research. When using this method, a roofing contractor will simply collect stereo video streams of a target roof. The captured data is processed to generate a 3D wire-diagram for every roof plane. In this process, distinctive visual features of the scene (e.g., 2D points and lines) are first automatically detected and matched between video frames. Matched features and the camera calibration information are used to compute an initial estimation of the 3D structure. Then, a hybrid bundle adjustment algorithm is used to refine the result and acquire the geometry that has the maximum likelihood. Afterwards, different roof planes are found and a measurable 3D wire-diagram is generated for each plane.
