Ink jet printing for textiles has brought many benefits to the textile print industry. It has an ability to print on demand, using thousands of colours, and at reduced costs compared with rotary screenprinting for small scale production, ink jet technology has already established itself as a reliable method of printing for the textile industry. This research investigates a new approach to ink jet technology. Numerous new surfaces are fed through a textile ink jet printer in the generation of bespoke printed textiles. This is an experimental approach to textile ink jet printing, recording practical solutions, and uncovering innovative processes for a new direction for digital technology for textiles. Various surfaces have been enhanced using screen print techniques and embroidery, or manipulated by hand and digitally printed in the production of an array of unique digital resist techniques. This research combines the use of textile hand craftsmanship with digital technology, crossing the boundaries and discovering ways of combining these disciplines. This research will highlights some of the possibilities with applying a hand crafted approach to ink jet technology for textiles, it demonstrate the control of colour, resist effects and the sensitivity of design which can be achieve using these new processes. In addition to this, the research will demonstrate the added value of this crafted approach to digital design, as well discussing the potential for reproducing these complex textile craft techniques and digital resist effects using CAD and ink jet technology.

The title of the project, ‘FutureFactories’, describes an exploration of direct digital manufacturing and the use of this technology in creating new models for consumer product design practice. In additive fabrication itself, there is no economic advantage in producing identical artefacts: given this, and the free-form potential of a technology that can deliver almost any form imaginable, the project examines the possibility of modifying the design with every artefact produced. The aim is to create automated systems capable of volume production, establishing mass individualisation: the industrial scale production of one-off artefacts. This work explores the potential to combine parametric CAD modelling with computer programming to create animated meta-designs that change in real time. These scripts introduce a random computer generated element into each physical product ‘printed out’ using direct digital manufacturing. The intention is to combine qualities normally associated with the vagaries of the hand-made with the technical resolution of industrial mass-manufacture; whilst at the same time maintaining a coherent design and identity. The outputs from this practice-based research project consist of inspirational products ranging from gallery pieces to commercial retail products and, alongside the real-world artefacts, the scripted meta-designs from which they are created. The use of such software processes and real-time networks as generative tools, questions existing transient boundaries of practice, and exposes the irrelevance of conventional definitions of role. It is clear that the outcomes of such a new model of creative production cannot be thought of as traditionally conceived pieces. The outcomes of the research suggest that the resulting artefacts can be considered both functionally useful and as art. Outside of that, existing definitions convey little of the reality of their production, as they lie in some new, as yet unspecified, arena of production.

Randek is a company that develops machines. The machines are used to build prefabricated houses. They have developed a CNC machine called Nailing Bridge that creates house walls. One of their issues is that they must predict the time it takes to build a wall because their customers need to know how long it takes to deliver their house. Our project solves this problem by making a program that calculates the time it takes to build a wall on the Nailing Bridge with help from NC files (Numerical Control files) consisting of G-code. One NC file contains the machine's operations, such as sawing, nailing, and routing. The goal was to develop a program with a maximum margin of error of 3% from reality. The machine was tested to measure the time of different operations to develop the program, and the NC files were analysed. Calculations for the jerk, acceleration, deceleration, and velocity of the CNC machine were considered to predict the time of the movements with high enough precision. The calculations and implementation are written in C#. A GUI is created for the user to use the program easily. The end product is a program that can take in one NC file and gives output on the time it should take for the Nailing Bridge to go through the file. The margin of error was between 5% to 31% for one operation of sawing or nailing, which is significantly higher than the goal of 3%. The program was therefore debugged with unit testing and new tests of the Nailing Bridge to find the sources for this margin of error. The conclusion is that the program works but not exactly to the company's standards.

The effects of Bacillus thuringiensis var. israelensis (Bti) on chironomid production was assessed in the New River in southern West Virginia. Production was measured in a year without Bti treatment (1987) and a year with treatment (1988). Sampling was conducted from June through November at Sandstone Falls, 16 km below Bluestone Dam in Summers County. Sampling was restricted to rock outcrops covered with Podostemum (river weed). Samples were collected at 2- wk intervals with a quantitative device that delineates an area of 0.01 m². Three species belonging to two genera accounted for about two-thirds of chironomid production in both years. Cohort production intervals were estimated to be 27 d for both species of Cricotopus and 20 d for P. convictum. Total chironomid production from June through November 1987 was 10.8 g/m² and during the same period in 1988 was 33.8 g/m². In 1987, the production of C. bicinctus and Cc. politus was 4.09 g/m² (38% of total chironomid production), and production of P. convictum was 2.46 g/m² (23%). In 1988, the production of C. bicinctus and C. politus was 12.39 g/m² (37%), and production of P. convictum was 11.38 g/m² (34%). Bti treatments caused no adverse effect on chironomid production in 1988, because the same species were dominant and their production was 3X higher. In addition, density and mean individual biomass were greater in 1988 than in 1987. The production increase in 1988 was probably related to environmental factors other than Bti treatments, such as discharge and Podostemum standing stock. / Master of Science

While it has been established that temperature can change the preconsolidation pressure of clays, the current understanding is limited to specific ranges of temperatures, with temperatures above freezing being studied entirely independently of temperatures below freezing. However, as temperature is a continuous domain and clays may be subjected to both above- and below- freezing temperatures over the course of an engineering application, a unified view is necessary. The first goal of this thesis is to develop a single model which can be used to predict the preconsolidation pressure of a normally consolidated clay at any temperature over a wide range which includes both frozen and elevated temperatures. To do so, consolidation tests were run at various temperatures between -7 °C and 50 °C, and the yield stress at each consolidation temperature was determined. As previous studies have established that the temperature response of clays is dependent upon their mechanical stress history, the specimens were consolidated initially at a reference temperature until they reached the normally consolidated state. Subsequently, the temperature of the specimens was changed and the volume changes during the temperature change stage were recorded. Once the specimens stabilized at the new temperature, they were consolidated once again and the preconsolidation pressure determined at the new consolidation temperature. The volumetric strains and changes in preconsolidation pressure for each temperature used in this study align generally with the previous data published for each temperature domain. Heating led to a decrease in the volume of the specimens, cooling to minimal strain, and freezing to an increase in the specimen volume. Changing the consolidation temperature by either heating, cooling, or freezing the specimen led to various degrees of increase in the preconsolidation pressure. A mathematical model was developed to fit the observed preconsolidation pressures at each consolidation temperature. This model can be used to predict the yield stress of NC kaolinite at any temperature within the tested range, and captures the smaller magnitude increases in yield stress which occur upon heating and cooling as well as the large increases which occur upon freezing the clay. With the effects of unidirectional thermal paths having been treated in the previous portion, a second investigation was also undertaken to assess how much of the temperature history of the soil might influence the behavior at its final consolidation temperature. In particular, the impacts of previous freezing on the preconsolidation pressure at elevated temperatures were investigated. The same clay material was first consolidated to the NC state and then frozen to -15 °C. Subsequently, the material was thawed or heated to various final temperatures and consolidated further to determine the preconsolidation pressure. The results of these tests indicate that the preconsolidation pressure was independent of the consolidation temperature for previously-frozen soil. While increasing contractive axial strains were recorded with increasing temperature, there was no accompanying increase in the preconsolidation pressure. These results indicate the thermal history of the clay can alter its behavior at the current temperature, overriding the effects of the most recent thermal path. / Master of Science / Temperatures around the globe are becoming more extreme every year due to global warming. The warming climate has destabilized permafrost. Additionally, new energy applications, such as heat exchange piles, and existing energy infrastructure, such as oil and gas pipelines, also constitute extreme thermal environments. The settlement of soils in these conditions must be well understood so that engineers can predict and mitigate potentially damaging conditions. One engineering parameter which is necessary to predicting the amount of consolidation settlement in clays is the overconsolidation ratio (OCR), and the preconsolidation pressure of clays is required in order to compute OCR. Previous studies have established that preconsolidation pressure is a function of temperature. However, in addition to changing soil temperatures due to climate, soil temperatures between in situ and laboratory settings where preconsolidation pressure is determined are often different as well. Therefore, in order to develop resilient foundations and structures in areas with thermal variations, a thorough understanding of how the preconsolidation pressure changes with temperature is necessary. The goal of this study is firstly to develop a mathematical model which can be used to predict the preconsolidation pressure of a clay over a wide temperature range which includes both frozen (<0 °C) and heated (>20 °C) temperatures. Consolidation tests were run on kaolinite clay specimens to determine the preconsolidation pressure at various temperatures within the chosen range. Then, a single expression was developed to allow the user to predict the preconsolidation pressure at any temperature within this range. While the mineralogy and stress state of the clay impact the parameters of this equation, the general form models the expected change in yield stress for a given change in temperature. The second goal is to assess whether the thermal history of the clay, in particular a prior frozen state, affects the preconsolidation pressure determined following subsequent thawing and heating.
