Show moreFor lasers, there exist many current and potential competitive applications in the areas of manufacturing, materials processing, and so on. Nanosecond (ns)-pulsed lasers are often seen in these applications. This dissertation presents the experimental study, time-resolved observation and analysis of nanosecond laser ablation and laser-induced plasma due to ablation, and the analysis is based on physics-based numerical models. Specifically, the following topics have been studied: (1). Plasma induced by ablation using long-duration nanosecond laser pulse Plasma is often produced in laser-material interactions, and may play an important role in many laser-based or laser-assisted technologies, such as laser shock peening (LSP), laser micromachining (through the laser ablation process), laser-induced breakdown spectroscopy (LIBS), and laser propulsion, etc. However, despite the previous work in the literature, the study is still limited for the plasma induced by the ablation process using long nanosecond laser pulses (with durations on the order of ~100 ns). In this dissertation, investigations have been performed on this kind of plasma through fast photography (imaging) and emission spectroscopy techniques, and the experimental results have been analyzed using physics-based computational models. Based on the investigations, the following major interesting findings have been obtained under the investigated conditions: (i) Two high radiation intensity regions are observed in the plasma, and one of them disappears soon after laser pulse ends. The research work shows that this phenomenon is related to the vaporization process from the target surface and the confinement effect of the ambient air. (ii) Laser-induced plasma xvii backward growth phenomenon occurs for target ablation using 100-ns laser pulses, but not for that using 200-ns pulses. The investigation shows that the underlying mechanism is the backward growth of the boundary of the high temperature region without actual backward motion of vapor material. (iii) Under the studied conditions, the core region of the plasma (~100 μm above the laser-ablated target) has relatively low temperatures as compared to some other regions of the plasma, which contradicts the common intuition. (2). Semiconductor ablation utilizing infrared (IR) nanosecond laser pulses Semiconductor micromachining through laser ablation may have the advantages of high spatial resolution, high processing efficiency, good flexibility, and no tool wear. However, most of the prior investigations in the literature on ns laser ablation of semiconductors often employ lasers at the ultraviolet (UV) or visible wavelength. The work using IR ns lasers is limited, but IR ns lasers may often have lower cost and require less external energy consumption to produce the same average laser power output. In this dissertation, the ablation of semiconductors using IR ns lasers has been studied through time-resolved observations (fast photography) and the results have been analyzed utilizing physics-based numerical models. The research work shows that the ablation mechanism under the studied conditions is the surface vaporization process during the early stage followed by the subsequent liquid ejection process that occurs at a later time. The research work and analysis shows that the underlying mechanism for the observed liquid ejection should be due to the spatial gradient of the pressure exerted on the target surface, instead of phase explosion. (3). Laser-induced backside ablation (LIBA) of sapphire with IR ns laser pulses xviii LIBA may potentially provide a good solution for high-quality and highefficiency micromachining of wide-band-gap dielectrics (WBGD). However, the prior work on LIBA of sapphire (which is a very important WBGD material) using low-cost IR ns lasers has been rarely reported. This kind of work has been carried out in this dissertation, and the investigation shows that under the studied conditions LIBA can produce very high material removal efficiency and reasonably good quality of machining without obvious chemical contamination coming from the employed backing layer. The ablation rate and damage threshold are measured under different laser parameters, and the research work may provide useful information for the applications of LIBA in practical areas using IR ns lasers that may often have relatively lower cost than UV or visible ns lasers.

Show moreHowell Mountain is a distinct and unique location in the heart of Napa Valley California. The 45 acres site rests on the mountain’s south west slopes and is planted with high quality grapes used in the production of red wine. When the fog rolls off the ocean and into the Napa Valley, the weather on Howell Mountain is generally sunny and cool. The appellation owes its distinctive climate to the fact that it is positioned high above the valley floor. The program includes both the wine production facilities and the hospitality facilities for visitors. The driving concept of the project is to merge those two, often opposing, programmatic elements. From west to east, the site has a 43% grade change. By designing a gravity flow winery, this facility can take advantage of that significant slope.

Show moreIn the 21st century, medical technology is advancing at a rapid rate, thus allowing people to benefit from new treatments being developed. However, much of the underserved and underinsured public are not benefiting from the breakthroughs as one might expect. In order for the existing facilities to better serve the public, gradual transformations and upgrades must be made. This is the challenge being tackled by our IPRO: How can we realistically suggest a renovation model for existing Access Community Health Network facilities which would promote cost efficiency and technological advancement in both environmental and operational capacities? - The primary objective of this session of IPRO 340 is to deliver a five-year model for which existing Access Community Healthcare facilities can be shaped into more environmentally and operationally efficient centers for medical treatment. - In designing such a model, secondary goals include familiarization with cutting edge medical technology, modernized building flow, spatial relations, as well as the development of business process models. In addition, we plan to investigate ways in which Access Community Healthcare can enhance the level of patient experience by making peoples’ visit to their facilities more enjoyable and informative.

Show moreThis is the second phase of this project as a continuation of Spring 2008 IPRO 317 and will have a focus for Summer 2008 on the computer program, the user interface, as well as completion of the first geographic area of the scale model. The objective of this project is to design and construct a 3-D scale model for the first portion of downtown Chicago (downtown Chicago has been subdivided into 6 portions). The model will be used to simulate and test the effectiveness of fire defense strategies to address fire or other catastrophes related to public health and safety. This model will include streets, buildings and detailed information that help the Chicago Fire Department in planning interventions, considering various scenarios and case studies. The model is being built in phases, with the overall design incorporating a sophisticated, computer-driven illumination scheme built within the model base. The model thus will be able to display animated scenarios of virtually any depth and focus, by means of time-varying color and brightness. CAD Computer-generated images and laser-cutting methods are the main techniques used to design and build the model, but hand craftsmanship is also necessary. The completed model will be fully modular, designed to transport easily to various facilities. The usefulness of the model thus will extend to many needs of the Chicago Fire Department and City of Chicago, as an educational tool within the department and for community outreach. Possible additional uses for the model will be wind tunnel measurement of pressure distributions to inform building design and City infrastructure needs, as well as the study of urban microclimates and the impact on building energy demand. There is also the potential for this model and its design approach to inform the development of scale models to depict the venues associated with the proposed 2016 Olympics along the Chicago lakefront. This project will include: (1) Identification of the scale, materials, technologies, and strategies for construction; (2) Physical mapping and computer modeling of the downtown built environment; (3) Design of the physical model and computer/electronic components; and (4) Construction of a reduced-area mock-up for final review and approval by the City of Chicago.
