Abstract
The Photographic and Spatial Survey Method for Video Projection
Jeffrey Paul Kurihara, M.F.A.
The University of Texas at Austin, 2013
Supervisor: Richard M. Isackes
The process and practices that are described in this document were used in several
realized video installation projects over the course of 2011-2013. These installations all
encompassed the use of Architectural Video Projection Mapping techniques to create
transformative animated video projections upon the pre-existing architecture of multiple
locations. The process used to achieve this required the integration of multiple practices
to obtain and translate specific spatial data to be used in the artistic content creation
process. Particular to this method uses a photographic and spatial survey to map the
video content accordingly to the architecture of the space. The projects included an
installation on a building facade for the Art Alliance Austin’s Holiday Stroll in 2011,
another installation on the architecture of an interior wall of a museum space for an event
at the Austin Museum of Art in 2013, a site-specific musical theater piece called Almost
Invincible in the University of Texas Co-op’s Cohen New Works Festival 2013, and
multiple stages of a live music venue named Cheer-up Charlie’s in Austin, Texas form
2011 to 2013. / text

Improving spectrum utilization in wireless networksBhartia, Apurv 09 February 2015 (has links)
With the proliferation of wireless-enabled devices, the information being transmitted on the wireless spectrum has increased manifolds. This explosive growth of wireless traffic has created spectrum crisis. Further, combined with the inherently lossy wireless medium, it is imperative to develop techniques that can significantly improve wireless spectrum efficiency. This dissertation develops three complementary techniques to enhance spectrum efficiency: (i) sending more information per transmission, (ii) sending more transmissions per spectrum, and (iii) selecting the right spectrum for transmission. More specifically, in (i), we observe that network coding allows us to send more information per transmission by combining (coding) multiple packets together in a single transmission and letting multiple receivers extract different information from the same transmission. However, wireless networks are inherently prone to loss and how to harness network coding gain under such conditions poses a significant challenge. To this end, we develop a novel routing protocol, called O3, which jointly optimizes network coding, opportunistic routing, and rate limiting. Multi-antenna devices (MIMO) dramatically increase wireless network capacity by sending multiple transmissions simultaneously. However, most existing work focuses on MIMO in single hop wireless networks, and how to effectively extend MIMO benefits to multihop wireless networks remain an open problem. In (ii), we propose a new routing protocol, called DM+, which is the first practical distributed MIMO routing protocol. It optimizes spatial multiplexing, routing, and rate limiting in the presence of interference. Using simulation and testbed experiments, we show it out-performs state-of-the-art shortest part routing and opportunistic routing protocols. Finally, in (iii), we examine spectrum selection at two different granularities: (a) selecting an appropriate channel to transmit a frame, and (b) selecting a subcarrier (within a channel) to transmit a symbol of the frame. In (a), we propose LBRH, a novel channel hopping algorithm that allows different nodes converge to a fair and efficient channel hopping sequence in a completely distributed fashion. In (b), we develop Smart-Fi, a series of techniques to harness the frequency diversity of the channel while transmitting the current frame. We demonstrate the effectiveness of both approaches using simulation and testbed experiments. / text

Foundations of a reverse engineering methodologyGuillory, Jeremy Barrett 17 June 2011 (has links)
Reverse engineering is broadly defined as the process of analyzing existing products to learn how to create better products in the future. Including reverse engineering as part of the engineering design process can provide a number of benefits, including a more thorough understanding of existing products, lower cost for the redesign of products, and faster times to market. While reverse engineering can be applied to a wide range of domains, this thesis deals with methodologies for extracting technical data from electro-mechanical products for the purpose of recreating them functionally and dimensionally, to an acceptable level of accuracy. An integrated and evolved reverse engineering methodology is presented. This new methodology is built upon previous work, and results from an effort to integrate all previous methods into the simplest and most useful form. Five novel reverse engineering techniques are introduced to solve problems previously unaddressed in the literature: Bounding Pertinent Geometry, Reassembly by Function, Determining Sample Size, Estimating Production Volume and Accounting for Physical Degradation. Throughout the thesis, a running example of the reverse engineering of the Craftsman Auto Hammer is used to illustrate the application of the evolved methodology. / text

Utveckling och design av spegelskåp för badrumGustavsson, Evelina, Schough, Camilla January 2007 (has links)
This report is a documentation of a Master’s thesis of 20 credits performed at the educational program of Technical Product- and Production Development with Design at Halmstad University. The project is carried out in cooperation with Hafa AB in Halmstad. The purpose of this project was to bring forth a concept of a bathroom cabinet for Hafa’s new selection Young through creative design methods. The selection is supposed to attract the younger purchaser but also a target group that dare to experiment with home furnishing and appreciates new design. This group is referred to as Young at Heart. To satisfy the needs identified in the initial development phase a specific design process model was developed that originates from Ullman´s “The Mechanical Design Process” and Landqvist’s “Vilda idéer och djuplodande analys”. The realization of the project was performed in four parts; problem analysis phase, idea generation phase, realization phase and resulting phase. In the design process it was included to carry out a thorough analysis of functionality, characteristics and design the bathroom cabinet should represent. Moreover, choice of material, construction details and lighting were other aspects of great importance for the mirror cabinet’s performance. A great range of tools were used with the purpose of reaching understanding of the product, the industry and the design process. Through quantitative interviews with the target group and the staff at Hafa, benchmarking and trend analysis, valuable information was gathered considering the preferred characteristics and design of a bathroom cabinet. The project resulted in a mirror cabinet representing innovative design, offering both open and concealed storage. The design differs from the competition, however represents the core values of Hafa, quality and elegance to reasonable price.

Augmented Reality Applications for Industrial RobotsLöfvendahl, Björn January 2014 (has links)
Augmented reality (AR) is a way of overlaying digital information onto a picture or a videofeed and has been used in industrial contexts for more than 20 years. This Master's Thesis examines if AR can be used to help maintenance engineers set up and maintain robot environments by visualizing robot movement and safety zones. The main result of the Master's Thesis is a prototype application for a tablet computer. The user points the tablet towards a robot filming it and the video feed is displayed on the screen. This video feed is augmented with a virtual zone displayed around the robot, illustratingthe area where the robot is allowed to move. The application fetches the coordinatesfor the zone from the safety system SafeMove { a system designed by ABB to increase safetyand allow closer human-robot collaboration.The visualization of a SafeMove conguration is currently limited to an image of atwo-dimensional coordinate system showing the zone as a set of dierent coordinates. Thismakes it dicult grasping the full layout of the three-dimensional zone. By using theapplication the user gets a better view of the layout, allowing the user to look at the robot from different sides and see the safety zone projected around the robot. User tests show that people working with SafeMove could benefit from using the application to verify the conguration of SafeMove systems and the conclusion is that AR, if used right, greatly can improve robot interaction and maintenance.
