This thesis is concerned with an Airline Gate Assignment problem that seeks to allocate gates to aircraft at an airport, using the objective of minimizing passenger walking distances. The problem is modeled as a variant of the quadratic assignment problem with set packing constraints. The quadratic objective function is then transformed into an equivalent linearized form by applying the first-order linearization technique of Sherali and Adams [1989, 1990]. In addition to linearizing the problem, the application of this technique generates additional constraints that provide a tighter linear programming representation. A suitable solution process that exploits the structure of the linearized problem is developed. Test results are presented using realistic data obtained from USAIR. / Master of Science

One's way of travel dictates one's perception of the surroundings; People's mode of transportation has also evolved greatly throughout the ages. From foot traffic to carriages, to cars and trains, we tend to travel in faster paces, on increasingly linear paths, and with less freedom to wander. In my opinion, it is starting to become difficult to appeal to this emerging group of moving spectators with traditional ways of building. In my thesis, I explore ways to design buildings that focus on creating perspectival images for the moving spectators who are traveling on modern transportation. / Master of Architecture

Flooding is impossible to prevent completely, consequences of excess water can however, be reduced and often avoided via flood risk management. With the increase in impermeable surfaces, approaches that have the intention of imitating natural drainage to manage storm-water are known as Sustainable (Urban) Drainage Systems (SUDS). Pollutants from vehicles have been identified as a concern in the urban environment, with origins including exhaust emissions, engine oil leakage and erosion of vehicle components. Investigation of vegetated parking surfaces (VPS) to limit the impact of pollutants are scarce, therefore this study aims to determine pollution tolerance of grass species for use in VPSs, prior to investigating the effects that vehicles have on a vegetated surfaces and alternative methods in which to analyse them. A pot trial investigated effects of increasing oil concentrations on the growth of four grass species. F. rubra L. was found to tolerate contamination to a higher degree than the other species and L. perenne L. produced more cumulative biomass throughout the investigation. A parallel study determined that Ca, Cu, K, Mg, Mo, P and Zn accumulated in grass shoots, indicating that F. rubra L. and L. perenne L. may be suitable for further analysis. field trial focused on a regularly-used L. perenne L.-covered VPS at a local school, analysing the influence of vehicles on vegetated parking bays. Compaction and mean element concentrations increased across the VPS, with distance from the roadside. Use of mineral magnetism as a proxy for geochemical detection did not prove successful as no significant correlation was identified between magnetic susceptibility (χ) and element concentration. Use of GIS provided this study with an alternative method for data presentation. Usually covering large scale analyses, an interactive geovisual map of geochemical dispersal and compaction across the VPS provided a novel method of visualising results from an investigation of this scale.

This report represents the bachelor thesis examination by Julia Kastehelmi Rintamäki. The examination has been performed during spring semester 2013 at Volvo Construction Equipment in Eskilstuna. This report, Development of parking brake component, describes the product development process of the parking brake component for articulated hauler, wheel loader and grader. Volvo CE has problems with the parking brake switch that exist today on articulated hauler, wheel loader and grader. The purpose of this project is to develop one common solution for the parking brake component for articulated hauler, wheel loader and grader. The secondary purpose is to find final concept proposal for each machine. Employees at the Volvo CE were interviewed; they were contacted via e-mail, phone calls and via meetings to get the information about the machines and the information around the parking brake component. Volvo CE databases were also used for gathering information about standards and pictures. Lots of different ideas were sketched and concept proposals were created with the aid of material from marketing analysis, competitor analysis, target group analysis, requirement specification, function analysis, standards and ergonomics. Eight concept proposals were chosen to be evaluated with QFD, Pugh’s matrix and FMEA. Two concepts were most suitable and developed further to three dimensional models with the aid of Solid Works. The different aspects were taken into account when designing and dimensioning the final concepts. Two models were created with the aid of plasticine for figuring out the ergonomics and dimensions of the product. DFM, DFA, DFE, D4S were used for taking into account costs, assembly, dimensions and environmental impacts of this product. One of the concepts could replace the existing parking brake switch and suit in different cabins because of its size and design. This concept can be located on vertical or on horizontal plane. The other final concept solution functions better for the  articulated hauler on account of the double function with exhausting brake system activating before parking brake system. Suggestion for next steps for the project could be to make prototypes of the two concepts and test these components in real machines. Also interviewing users for further development of the final concepts and redesign if needed.

The surface parking lot was a key element in the destruction of traditional public space. It fragmented the fabric of traditional cities, prompting the sprawl of twentieth century cities and suburbs. The automobile permitted the average individual, for the first time in history, to move through public space insulated in a private shell, shielded from strangers and protected from undesirables. Consequently, the role of the sidewalk dwindled. The automobile and the parking lot dominated the pedestrian and the sidewalk, whose diminished vitality further encouraged widespread automobile use. As a result, the parking lot became one of the defining features of the American city. In the United States parking lots are expected to be utilitarian, prevalent and free. Even as traditional public spaces disappeared, there was little demand for new public spaces, particularly not in the parking lot. Through investigations of parking history and public space, this thesis argues that parking lots, by virtue of their visual and physical accessibility, are contemporary public space. Although they are singular in their use, in contrast to the multifaceted street, parking lots are the settings for modern public life. This thesis further asserts that the simple landscape of the utilitarian parking lot can be transformed into complex public space, thereby enlivening the public realm.

The site is in a garage area in the state capitol complex, Austin Texas. Even though this place is located near by important government facilities and public park and links between UT Campus and Central Business District, there are no people who enjoy the place because there are no function except parking. There are just authoritative and mono-cultural office buildings and boring parking buildings. On the street, there are no trees, retails, and galleries for pedestrians. Existing parking buildings are same type and structure. Because the city has several plans to develop this area in the future such as Waller Creek Development, UT Medical School Master Plan, and Austin's Urban Rail, you can see the importance of this area. The most critical problem is this area is cutting the relationship between UT Campus and Downtown. My question is "How can a new type of parking building contribute to make the Texas Capitol Complex good place?" So I suggest a new type of mix-used parking building. The project goal is to gather people, link separated places: The State Capitol, Waller Creek, UT Campus, CBD, intermingle different functions: garage, gallery, shop, theater, restaurant, lounge, pool, park, and then make the place more dynamic, enjoyable and energetic place. Further, I expect that Austin become interesting city to live and visit through like this new place. / text
