Abstract:
Abstract We consider nonsymmetric hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of commutative nonsymmetric association schemes. First, we give a characterization of the eigenmatrix of a commutative nonsymmetric association scheme of class 3 whose Bose-Mesner algebra contains a nonsymmetric hermitian complex Hadamard matrix, and show that such a complex Hadamard matrix is necessarily a Butson-type complex Hadamard matrix whose entries are 4-th roots of unity.We also give nonsymmetric association schemes X of class 6 on Galois rings of characteristic 4, and classify hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of X. It is shown that such a matrix is again necessarily a Butson-type complex Hadamard matrix whose entries are 4-th roots of unity.

We show that for codes meeting the Plotkin bound, the distribution on R induced by projection onto a coordinate has an interesting property. We present several constructions of codes meeting the Plotkin bound and of Plotkin-optimal codes. We also investigate the relationship between Butson–Hadamard matrices and codes over R meeting the Plotkin bound.

Abstract:
In this thesis we study the application of trace maps over Galois fields and Galois rings in the construction of non-binary linear and non-linear codes and mutually unbiased bases. Properties of the trace map over the Galois fields and Galois rings has been used very successfully in the construction of cocyclic Hadamard, complex Hadamard and Butson Hadamard matrices and consequently to construct linear codes over integers modulo prime and prime powers. These results provide motivation to extend this work to construct codes over integers modulo . The prime factorization of integers paved the way to focus our attention on the direct product of Galois rings and Galois fields of the same degree. We define a new map over the direct product of Galois rings and Galois fields by using the usual trace maps. We study the fundamental properties of the this map and notice that these are very similar to that of the trace map over Galois rings and Galois fields. As such this map called the trace-like map and is used to construct cocyclic Butson Hadamard matrices and consequently to construct linear codes over integers modulo . We notice that the codes construct in this way over the integers modulo 6 is simplex code of type . A further generalization of the trace-like map called the weighted-trace map is defined over the direct product of Galois rings and Galois fields of different degrees. We use the weighted-trace map to construct some non-linear codes and mutually unbiased bases of odd integer dimensions. Further more we study the distribution of over the Galois fields of degree 2 and use it to construct 2-dimensional, two-weight, self-orthogonal codes and constant weight codes over integers modulo prime.

Cute As A Button explores powerlessness, vulnerability, illness and addiction all wrapped up in tender buttons and a cute, cuddly creature. Using animation, sculpture, sound and an intimate space, I surround the viewer in a saccharine nightmare, one that references the dark underbelly of the cute and the sweet. The visual and aural elements are representative of the psychological and emotional states of powerlessness, which are overcome by the act of making and exploring a medium over which I can have complete control.

Abstract:
The technological, sociological and cultural position of television, as a method of delivering content, has been the subject of much academic debate in the past twenty years. Perceived threats to television have emerged through the convergence of technologies, which has enabled traditional media forms to take on the characteristics of each other. As a result there is no such thing as a dominant communications medium in the 21st Century, as shared technological characteristics mean that the user can access a multitude of content through one single device. Some believe that television is on the wane, leading to dire predictions of the ‘death’ of television. For others, if television is to survive and develop as a communications medium, it needs to take on one element of convergence by becoming more interactive. There is a substantial amount of academic work which suggests how television can achieve this and what the content provided will do. However, these are merely suggestions, as there is no research which looks at what interactive content actually is. The assumption for scholars, who believe that interactive television is a viable format, is that it is inevitable that interactivity will become an everyday element of television use. Ideas as to how this can be achieved have been put forward but have not been followed up. This research aims to fill that empirical gap and is informed not by what could be but what is. It is clear that digital television has allowed for an additional stream of information to be accessed, through the red button on the remote control. This content provides a variety of options for the viewer, however, the key question, which this research is addressing, is how much of it is interactive? Additional research is now needed to establish just how much of this content exists, what the red button allows the audience member to do and how. Therefore it is necessary to measure and quantify the amount of red button content across a sample of channels, which represent the three types of broadcasting comprising the British broadcasting landscape; public service (the BBC), commercial (ITV) and subscription (Sky).

Abstract:
Syftet med detta arbete var att undersöka hur man skulle kunna gå till väga för att skriva låttexter genom att ha en film som inspirationskälla. Jag har skrivit tre låtar baserade på filmen ”The Curious Case of Benjamin Button”. Jag kollade igenom filmen två gånger och valde sedan ut scener och karaktärer att jobba vidare med. Det kunde till exempel vara scener med mycket substans att skriva om, samt scener som väckte min egna nyfikenhet. Materialet jag fick utav denna process resulterade i specifika, tidskodade scener och citat från filmen som jag delade upp i separata anteckningar. Detta arbete resulterade i tre låtar där låt 1 har mest fokus på en karaktär, låt 2 har mest fokus på en historia och där låt 3 har mest fokus på en känsla. Musiken är intuitivt skriven och har som syfte att backa upp texten. Jag lärde mig hur viktigt det är med förarbete, och att just ha en metod när man skriver text. Har man det så har man också alltid något att gå tillbaka till. Förhoppningen är att denna metod skall kunna upprepas oavsett vilken genre man helst jobbar med som låtskrivare.

Abstract:
Traditional call button networks that control elevator systems utilize a wired connection for communication. The communication cables are run through the elevator shaft from one call button to another and finally to the controller on the roof. Installing this wired link is highly time consuming. In this thesis, we propose the design for a wireless call button network. Two important features of this wireless network design are low cost and low power consumption. Controller Area Network (CAN) is a widely used protocol for wired networks and has been proposed for use in next generation elevator control systems. A modified CAN for wireless (MCANW) protocol has been developed for the wireless call button network. The wireless link will be implemented via the use of data radios. A modified form of traditional Binary Phase Shift Keying (BPSK) modulation scheme for the radios is proposed. The proposed modulation scheme, like differential BPSK, can be detected non-coherently but it offers better performance than differential BPSK. Its implementation includes an innovative tracking algorithm to maintain synchronization at the receiver.

Abstract:
Thesis (M.A.)--Boston University
Vitamin D has proven to be an important factor in health through a plethora of studies. Tachysterol is a photoproduct of previtamin D with sun or ultraviolet radiation exposure. While vitamin D is well known for its importance in bone health, the biologic function of tachysterol is unknown. Many vertebrates and fungi can produce vitamin D from a precursor after UV irradiation or sun exposure, including white button mushrooms. This project aims to determine if tachysterol might have a biologic function in white button mushrooms by determining if the disappearance of tachysterol2 was due to some active process in live mushrooms. To provide evidence that tachysterol serves a function, tachysterol2 disappearance in white button mushrooms was monitored after 24 hours. The aim was to create conditions in a white button mushroom, including freezing and microwaving them to determine their effects on tachysterol2 disappearance at 24 hours. The idea was that freezing or microwaving the mushroom would disrupt any metabolic process in the mushroom, providing a clue as to the mechanism of tachysterol2 disappearance. The hypothesis was that freezing and microwaving the white button mushroom would cause a reduction in tachysterol2 disappearance. To evaluate this, 1) white button mushrooms were irradiated with ultraviolet radiation (UVB, 290nm-320nm), 2) an irradiated white button mushroom was frozen, and 3) an irradiated white button mushroom was microwaved. These white button mushrooms were biopsied in triplicate, extracted, and run on high-performance liquid chromatography in order to determine the concentrations of tachysterol2 in the mushrooms. A white button mushroom without UVB irradiation was biopsied in triplicate and extracted to confirm that the store-bought mushrooms did not contain tachysterol2. A tachysterol2 standard was incubated in organic solvent to determine if tachysterol2 was stable. The results showed statistically significant decrease in tachysterol2 for the irradiated mushroom, the frozen irradiated mushroom, the microwaved mushroom 24 hours after irradiation, compared to the standard tachysterol2 in organic solvent. The decrease in tachysterol2 in the microwaved mushroom was 65% in 24 hours, which was not significantly less than in the irradiated mushroom and the frozen irradiated mushroom (p= 0.10 and 0.22, respectively). The decrease in tachysterol2 for the frozen mushroom was 93%, which was not significantly less than the irradiated mushroom (p = 0.21). These findings suggest that microwaving a mushroom at 5mW and 60 seconds and freezing a mushroom does not significantly interfere with metabolic processes that may involve tachysterol2, although microwaving a mushroom trended towards less of a decrease in the tachysterol concentration.

Kaaresoja, Topi Johannes. "Latency guidelines for touchscreen virtual button feedback." Thesis, University of Glasgow, 2016. http://theses.gla.ac.uk/7075/.

Full text
Abstract:
Touchscreens are very widely used, especially in mobile phones. They feature many interaction methods, pressing a virtual button being one of the most popular ones. In addition to an inherent visual feedback, virtual button can provide audio and tactile feedback. Since mobile phones are essentially computers, the processing causes latencies in interaction. However, it has not been known, if the latency is an issue in mobile touchscreen virtual button interaction, and what the latency recommendations for visual, audio and tactile feedback are. The research in this thesis has investigated multimodal latency in mobile touchscreen virtual button interaction. For the first time, an affordable, but accurate tool was built to measure all three feedback latencies in touchscreens. For the first time, simultaneity perception of touch and feedback, as well as the effect of latency on virtual button perceived quality has been studied and thresholds found for both unimodal and bimodal feedback. The results from these studies were combined as latency guidelines for the first time. These guidelines enable interaction designers to establish requirements for mobile phone engineers to optimise the latencies on the right level. The latency measurement tool consisted of a high-speed camera, a microphone and an accelerometer for visual, audio and tactile feedback measurements. It was built with off-the-shelf components and, in addition, it was portable. Therefore, it could be copied at low cost or moved wherever needed. The tool enables touchscreen interaction designers to validate latencies in their experiments, making their results more valuable and accurate. The tool could benefit the touchscreen phone manufacturers, since it enables engineers to validate latencies during development of mobile phones. The tool has been used in mobile phone R&D within Nokia Corporation and for validation of a research device within the University of Glasgow. The guidelines established for unimodal feedback was as follows: visual feedback latency should be between 30 and 85 ms, audio between 20 and 70 ms and tactile between 5 and 50 ms. The guidelines were found to be different for bimodal feedback: visual feedback latency should be 95 and audio 70 ms when the feedback was visual-audio, visual 100 and tactile 55 ms when the feedback was visual-tactile and tactile 25 and audio 100 ms when the feedback was tactile-audio. These guidelines will help engineers and interaction designers to select and optimise latencies to be low enough, but not too low. Designers using these guidelines will make sure that most of the users will both perceive the feedback as simultaneous with their touch and experience high quality virtual buttons. The results from this thesis show that latency has a remarkable effect on touchscreen virtual buttons, and it is a key part of virtual button feedback design. The novel results enable researchers, designers and engineers to master the effect of latencies in research and development. This will lead to more accurate and reliable research results and help mobile phone manufacturers make better products.

Abstract:
This research describes a theoretical framework for designing multimodal feedback for 3D buttons in a virtual environment. Virtual button implementations often suffer from inadequate feedback compared to their mechanical, real-world, counterparts. This lack of feedback can lead to accidental button actuations and reduce the user’s ability to discover how to interact with the virtual button. We propose a framework for more expressive virtual button feedback that communicates visual, audio, and haptic feedback to the user. We apply the theoretical framework by implementing a software library prototype to support multimodal feedback from virtual buttons in a 3D virtual reality workspace.

Abstract:
Abstract Thermal barrier coatings (TBC) are used to protect the hot components of gas turbine engines to enhance thermal efficiency and component service life. It is critical for TBC development that a testing method be used to understand the potential and limitation of coating’s durability and integrity under the gas turbine engine operation conditions. In this paper, laser high heat flux testing with an applied temperature gradient across TBC coated buttons is presented. The ceramic coating is ZrO2-8 wt.% Y2O3 applied via the air plasma spraying process on top of a NiCoCrAlY bond coating and an Inconel alloy substrate button of 25.4 mm diameter. The coated button is subject to precisely-controlled laser heating on the top side (1150°C) and temperature gradient of 63.9°C/mm through the button overall thickness. The TBC button lasts 160.9 hr or 570 cycles of laser heating. Analysis of void fraction change before and after the test, thermal conductivity change during the laser test, and failure assessment are presented. After the test, the top coating has cracks in vertical or oblique directions and significant horizontal cracks near the top coating and bond coating interface. Significant horizontal top coating cracks close to the interface between the top coating and bond coating appear near the button center. Although the coating delamination has not occurred yet, at the end of the laser testing the button is close to delamination. Based on the horizontal cracks and the thermally grown oxide layer geometry, a finite element analysis is conducted to calculate the residual stress and the strain energy release rate. A possible approach to combine laser rig test result and finite element computation for developing a TBC service life model is discussed.

This paper presents both experimental and numerical results demonstrating the dramatic effect of a particular geometric discontinuity on the flow within a highly-loaded single-stage transonic compressor. This compressor features cantilevered variable-stagger stator vanes (VSV) with buttons at the outer radius partially standing out in the annulus, by a value of about 0.3 mm which amounts to 0.5% of vane height. The first tests of this compressor revealed a very large corner flow separation at the stator outer radius. This feature could not be reproduced by steady 3D Navier-Stokes computations of the stator flow field with a smooth flowpath. However, using a simple numerical approach to account for the actual geometric discontinuity of the annulus, the computation then showed flow trends similar to that of the experiment. Also, a detailed analysis of the computed flow field indicated that the flow turning (both radial and tangential) due to the button blockage contributed toward strengthening the effect of secondary flows. Subsequently, after the button geometry was corrected to match the flowpath, further tests confirmed a much more satisfactory flow behaviour within the stator vanes leading to a one point improvement in compressor isentropic efficiency. This study leads to the conclusion that ensuring a smooth flowpath can be critically important for the high stage leadings characteristic of advanced military applications. Moreover, the predictive value of 3D Navier-Stokes computations for the simulation of technological effects, such as VSV buttons / flowpath mismatch, is clearly demonstrated.
