The aim of this thesis is to develop conservation principles for the brick and tile industry in Eskisehir, one of the symbolic industrial cities in Turkey where brick and tile has been the significant production from the Early Republic Period. The conservation of these structures, complexes and mechanical elements is a controversial issue owing to their physical, economical, social and administrative values. The principles how to conserve and why is searched through discussions on conservation approaches, development plans and values. Focusing on this aim, this study is structured in six parts as the research on industrialization and industrial heritage, review and discussion of value types, survey on brick and tile industry, the value assessment process for the factories with the proposed value types and the implementation of conservation principles. In conclusion, the development of principles is an essential process in conservation of cultural heritage. This thesis proposes conservation principles over physical, social and administrative structure for industrial heritage for brick and tile factories in the Eskisehir Industrial Area.

Abstract Permeable reactive barrier technology is a cost effective means of treating near surface groundwater contaminant plumes. However, current reactive barrier technology lacks the capacity to manipulate flow rates and thus hydraulic retention time (HRT) within the barriers in order to maximize the effectiveness and longevity of the media. This study examines the effectiveness of tile drains as passive controls on the flow rate of ground-water through an existing wood particle media permeable reactive barrier treating agricultural nitrate. The use of upgradient and downgradient tile drains allowed HRT to be increased from 4.5 to 10 days in one trial and then to be decreased from 11.1 to 0.8 days in a second trial. Influent groundwater NO3-N concentrations of ~100 mg/L were attenuated to detection limit (0.02 mg/L) only 12% of the 4 m long barrier with HRTs of 4.5 to 10 days. During the second trial, HRT was decreased to 0.8 days and NO3-N penetrated to the downgradient edge of the PRB at 1.8 mg/L. The behaviour of SO4 in the PRB was also affected by flow rate. SO4 entered the PRB at 60 to 71 mg/L during the first trial. Under a HRT of 10 days it was depleted to detection limit after traveling through only 13% of the barrier. When HRT was decreased to 4.5 days, SO4 was able to penetrate the downgradient edge of the PRB at concentrations from 4 to 6 mg/L. With a 0.8 day HRT SO4 reduction was highly restricted as calculations showed 90% of available carbon in the PRB was being used to reduce NO3-N, compared to 7.5% being used for SO4 reduction at that time. In comparison, at the 10 day HRT, 61% of carbon being used for NO3-N reduction, 8.7% for SO4 reduction, 0.7 for dissolved oxygen and 29% was lost through DOC leaching. These calculations suggest that barrier efficiency can be greatly enhanced by manipulation of HRT through use of tile drains.

A modular and area-efficient 3D graphics accelerator for tile based rendering in FPGA systems has been designed and implemented. The accelerator supports a subset of OpenGL, with features such as mipmapping, multitexturing and blending. The accelerator consists of a software component for projection and clipping of triangles, as well as a hardware component for rasterization, coloring and video output. Trade-offs made between area, performance and functionality have been described and justified. In order to evaluate the functionality and performance of the accelerator, it has been tested with two different applications. / En modulär och utrymmeseffektiv 3D-grafikaccelerator för tile-baserad rendering i FPGA-system har designats och implementerats. Acceleratorn stöder en delmängd av OpenGL med funktioner som mipmapping, multitexturering och blending. Acceleratorn är uppdelad i en mjukvarudel för projektion och klippning av trianglar och en hårdvarudel för rastrering, färgsättning och utritning till skärm. Avvägningar som gjorts mellan area, prestanda och funktionalitet har beskrivits och motiverats. För att evaulera funktionalitet och prestanda har acceleratorn testats med två olika applikationer.

The underlying objective of this research is to improve the overall understanding of how spatial and temporal variability in macroporosity and soil hydraulic properties in the shallow subsurface influence the long term mobility of agricultural nutrients, and specifically the movement of liquid swine manure, in macroporous, tile drained soils. The principal motivation for the work was to provide insight into dynamic nutrient mobility in this type of agricultural environment in order to guide both the efficiency and environmental sustainability of nutrient management practices. The results of this work facilitate the advancement of our conceptual understanding and our ability to simulate preferential flow and transport in structured agricultural soils that are subject to seasonal hydrologic patterns similar to those found in the humid continental climate of southwestern Ontario

Magnesium oxychloride cement (MOC) based grinding and polishing bricks developed for polishing of granite based ceramic tiles were produced and characterized. For surface grinding 46 and 180 grit size SiO2 powder embedded MOC based abrasive bricks / for polishing 600 and 1200 grit size SiC powder embedded MOC based abrasive bricks followed by neat (unreinforced) MOC pastes were applied on ceramic tiles. Three different neat MOC pastes depending on MgO/MgCl2 molar ratio in the paste e.g. 6/1, 7/1, and 8/1, were formed and evaluated. Grinding bricks were formed by adding 30 weight percentage, wt%, of both SiO2 powders. Polishing bricks were formed by adding 20, 25, and 30 wt% of both SiC powders. X-Ray diffraction analyses revealed that MOC F5 was the main crystalline phase in the neat MOC pastes. Additions of both SiO2 and SiC powders enhanced mechanical properties namely / compressive strength and abrasion resistance, chemical durability in water and polishing ability of MOC paste. More than 25 wt% addition of SiC powders had a tendency to decrease the compressive strength and water resistance of MOC paste. Polishing performance of abrasive bricks was evaluated in terms of mean surface roughness of ceramic tiles and abrasive brick consumption upon polishing. Scanning Electron Microscope examinations revealed the evidences of the reasons that 25 wt% SiC powder embedded abrasive bricks has the best qualifications in terms of abrasion resistance and polishing performance.

Detta projekt gjordes med syfte att få upp ögonen för problematiken kring hur mycket trämaterial som går till spillo hos diverse snickerier i Sverige. Material som är fullt funktionellt men som inte anses som användbart för möbeltillverkning och annan användning, mals ner och bränns efter det slängts på hög. I detta arbete har ett skivmaterial formgivits och designats av spillbitar i trä. Detta för att sedan kunna användas som dekoration på golv, väggar, tak och även möbler. På så sätt berättas träets livshistoria och samtidigt uppmärksammas träslaget som material och dess möjligheter inom inredningsdesign / The aim with this project was to act as an eye opener for the problematic regarding the respect for wooden waste materials thrown away every day at Swedish wood companies. A lot of material, that is completely functional, but is considered as too defect and therefore useless for wooded furniture factories, is grained down to dust and chippings to eventually getting burnt to ashes and stocked in piles.In this project, a wooden tile was designed and hand crafted from waste wood. The tile was created to use as a décor for floors and walls as well as ceilings and furniture. This to communicate the true life story of the wooden waste as well as to raise awareness of wood as a material and its possibilities in interior design.

The purpose of this creative project was to research, build, and replicate portions of the history of the town of Bradford, Ohio in order to create a permanent community monument. Glazed tiles were mounted together to form an artpiece four feet by sixteen feet, preserved for future generations to appreciate and enjoy.Upon completion of research on the community, drawings of area business establishmentswere diligently developed for the clay bas relief tiles, which were sculptured by the artist and his Art I-IV students. Individual clay tiles, composed of terra-cotta stoneware, were bisque fired, underglazed, and refired. To mount the tiles, concrete was applied to sections of plywood (which had been covered with chicken wire). The stoneware tiles were then organized, arranged, and embedded in concrete to create a mosaic mural.The process of the mural forged an unmistakable bond between teacher, students, school, and community. The completed mosaic mural was framed and permanently mounted on location at the Bradford Public Library, 138 E. Main Street, Bradford, Ohio, involving the remodelling of the facility to accommodate the sculpture's size. / Department of Art

Title: Monte Carlo Simulations of the Tile Calorimeter and Measurement of the Z → ττ Cross Section with the ATLAS Detector Author: Mgr. Jana Nováková Department: Institute of Particle and Nuclear Physics (IPNP) Supervisor: RNDr. Tomáš Davídek, PhD., IPNP Supervisor's e-mail address: davidek@ipnp.troja.mff.cuni.cz Abstract: The Monte Carlo simulations of the Tile calorimeter in the ATLAS experiment at the LHC, especially the electronic noise and multiple interactions (co-called pile-up), are discussed in the thesis. A good agreement in the cell energy distribution between data and Monte Carlo simulations is found. The cross section measurement of Z → ττ events with the ττ invariant mass between 66 and 116 GeV with the ATLAS experiment is described in the next part of the thesis. Data samples collected during 2011 corresponding to the integrated luminosity of 1.34 - 1.55 fb−1 are used for the analysis. The measurements are performed in three different final states depending on the decay mode of the τ leptons. The measurement in the channel with one τ lepton decaying leptonically into the electron + neutrinos (schematically τ → e + νe + ντ ) and the other one hadronically (schematically τ → hadrons + ντ ), especially the calculation of the nominal cross section and the evaluation of the systematic...
