Ashbrook, Daniel Lee. "Enabling mobile microinteractions." Diss., Georgia Institute of Technology, 2010. http://hdl.handle.net/1853/33986.
Full textAbstract:
While much attention has been paid to the usability of desktop computers, mobile com- puters are quickly becoming the dominant platform. Because mobile computers may be used in nearly any situation--including while the user is actually in motion, or performing other tasks--interfaces designed for stationary use may be inappropriate, and alternative interfaces should be considered.
In this dissertation I consider the idea of microinteractions--interactions with a device that take less than four seconds to initiate and complete. Microinteractions are desirable because they may minimize interruption; that is, they allow for a tiny burst of interaction with a device so that the user can quickly return to the task at hand.
My research concentrates on methods for applying microinteractions through wrist- based interaction. I consider two modalities for this interaction: touchscreens and motion- based gestures. In the case of touchscreens, I consider the interface implications of making touchscreen watches usable with the finger, instead of the usual stylus, and investigate users' performance with a round touchscreen. For gesture-based interaction, I present a tool, MAGIC, for designing gesture-based interactive system, and detail the evaluation of the tool.

Full textAbstract:
The increasing demand for connectivity and broadband wireless access is leading to the fifth generation (5G) of cellular networks. The overall scope of 5G is greater in client width and diversity than in previous generations, requiring substantial changes to network topologies and air interfaces. This divergence from existing network designs is prompting a massive growth in research, with the U.S. government alone investing $400 million in advanced wireless technologies. 5G is projected to enable the connectivity of 20 billion devices by 2020, and dominate such areas as vehicular networking and the Internet of Things. However, many challenges exist to enable large scale deployment and general adoption of the cellular industries. In this dissertation, we propose three new additions to the literature to further the progression 5G development. These additions approach 5G from top down and bottom up perspectives considering interference modeling and physical layer prototyping. Heterogeneous deployments are considered from a purely analytical perspective, modeling co-channel interference between and among both macrocell and femtocell tiers. We further enhance these models with parameterized directional antennas and integrate them into a novel mixed point process study of the network. At the air interface, we examine Software-Defined Radio (SDR) development of physical link level simulations. First, we introduce a new algorithm acceleration framework for MATLAB, enabling real-time and concurrent applications. Extensible beyond SDR alone, this dataflow framework can provide application speedup for stream-based or data dependent processing. Furthermore, using SDRs we develop a localization testbed for dense deployments of 5G smallcells. Providing real-time tracking of targets using foundational direction of arrival estimation techniques, including a new OFDM based correlation implementation.

The appropriate framework to capture and share location information with mobile applications enable the development of interfaces and interface techniques that empower users to obtain and share information on the go. As such, the work in this thesis makes two major contributions. First is the SeeVT framework, a locative backbone that uses currently-available data and equipment in the Virginia Tech and Blacksburg VA environments (e.g., wireless signal triangulation, GPS signals) to make available to applications the location of the device in use. Applications built on this framework have available knowledge of the region in which the userâ s device is located. Second is a set of four applications built on the SeeVT framework: SeeVT â Alumni Edition (a guide for alumni returning to campus, often after lengthy absences), the Newman Project (a library information system for finding books and other library resources), VTAssist (a information sharing system for disabled users), and SeeVT-Art (a guide for users in our local inn and conference center to learn about the art on display). Key in this contribution is our identification and discussion of three interface techniques that emerged from our development efforts: an images-first presentation of information, a lightweight mobile augmented reality style of interaction, and locative content affordances that provide ways to quickly input focused types of information in mobile situations.Master of Science

Full textAbstract:
Den här kandidatuppsatsen undersökte huruvida idégenerering påverkades av musik i förhållande till antal idéer, lämplighet och unicitet. Musikens eventuella effekt jämfördes även med deltagarnas musikpreferenser och kreativitetskarakteristik, med avsikten att svara på om dessa faktorer var relevanta för musikens möjliga påverkan av idégenerering eller inte. 16 deltagare delades in i tre grupper och genomförde ett idégenereringsexperiment. Två av grupperna lyssnade på två olika sorters musik under experimentet, en per grupp, och den tredje gruppen arbetade under tystnad. Alla deltagare svarade sedan på ett mindre formulär, och de flesta utförde ett test för att avgöra individens kreativitetskarakteristik. Resultaten var otydliga och data räckte inte till för att avgöra om musiken hade en effekt, men det fanns flera intressanta aspekter. Gruppen som lyssnade på repetitiv musik kan ha påverkats så att de var benägna att producera repetitiva idéer. Dödsmetall kan i sin tur ha gjort att grupp 2 tappade koncentrationen och således producerade färre idéer, men musiken verkar inte ha påverkat deras förmåga i förhållande till lämplighet och unicitet. Även om musiken kan ha varit en faktor så fanns det flera andra potentiella faktorer, såsom upwards och downwards comparison, andra sociala faktorer och personliga faktorer för varje deltagare. Till sist så var deltagarnas musikpreferenser eller självrapporterade kreativitetskarakteristik inte relevanta faktorer för att avgöra deltagarnas idégenereringsförmåga.This undergraduate thesis examined the effect music had on idea generation in terms of number of ideas, the appropriateness of ideas and the uniqueness of ideas. Furthermore, the possible effect of the music was compared to the participant’s preferences in music and characteristics in creativity, with the intent to answer whether these factors were relevant for the possible effect of music during idea generation or not. 16 participants divided into three groups performed an experiment in idea generation. Two of the groups listened to two different types of music during the experiment, one for each group, the third generated ideas in a silent room. All participants then answered a small questionnaire, and most answered a test measuring their creative characteristics. The results were inconclusive, and the data was not enough to determine the music as a cause, still there were several interesting aspects. The group listening to repetitive music may have been affected so that they were inclined to repeat ideas, while death metal seem to have caused the second group to lose concentration and in turn produce fewer ideas. The second group did however not seem to be affected in terms of the appropriateness or uniqueness of their ideas. Even though music may have been a factor, other potential factors are upwards and downwards comparison, other social factors and the personal factors of each participant. Finally, the participant’s preferences in music and self-reported characteristics in creativity were not relevant factors in determining their ability to generate ideas.

This thesis discusses environmental partnerships, in which an NGO and corporation collaborate to address mutual goals. I begin by discussing the goals of environmental partnerships before reviewing a brief history of these partnerships, the current state of the partnerships landscape, and partnership trends across industries and within NGOs. Next, I examine the potential benefits and drawbacks to partnering for both public and private participants. Finally, strategies for corporations, NGOs, research institutes, academia, and government to enable the creation and maintenance of successful partnerships are proposed to address critical environmental issues in the absence of effective regulation.

Full textAbstract:
As computing devices become increasingly portable, it is becoming necessary to support Mobility as a core network functionality. The availability of devices such as smartphones, tablets, laptops as well as wireless network infrastructure is opening up the possibility of using Network Mobility to cater for multiple mobile nodes simultaneously. Network mobility may be useful in a number of mobile scenarios, where a large number of mobile nodes are moving in unison. A number of operational benefits stand to be gained by aggregating these nodes into a single mobile unit. Unfortunately, the current state for network mobility support, especially in terms of network layer protocols, is limited. This is in part due to the inherent complexity of mobile network scenarios, the high cost of testing mobile network protocols in operational environments and the difficulties in implementing such protocols. This thesis looks at how network mobility support may be better enabled by making experimentation with mobile networks more accessible. It shows this by first showing how analytical approaches can be useful in mobile network applications, as they abstract away from experimental details and allow for more straight forward protocol comparisons. It then goes on to look at the tools available to study mobile network protocols, where it introduces and extends an existing tool that uses virtual machines to allow for the study of mobile network protocols. Finally, it demonstrates a practical method in which mobile network support may be easily enabled in a practical setting.

Global operations for multinational companies today pose a particularly challenging environment for maintaining fluid knowledge transfer and effective communication methodologies. In a continuous drive for product innovation, process development often takes on lower priority to other initiatives that directly affect the design and delivery of a product. However, existing literature shows that process development and governance are critical to sustainable growth in the global marketplace. Multinational companies must recognize the need to integrate process development in a product centric enterprise to maintain effective information flow and clear communication channels. Cisco faces this challenging in maintaining effective cross-functional communication while growing through acquisition and new product developments. Cisco also faces additional complexity in managing a global network of outsourced manufacturing activities. This research analyzes two case studies in process development within the Manufacturing organization at Cisco. Specifically, these two case studies focus on driving early engagement of manufacturing concerns in the product lifecycle and effective means of facilitating this initiative.

CAD (Computer Aided Design) software allows one to describe a design in great detail and at any arbitary scale. However, our interface to CAD is still largely through traditional avenues: screen, keyboard and pointing devices. While these interfaces function for their intended purposes: text entry, pointing, browsing, etc, they are not designed for the purpose of mediating the flow of information from and to a physical workpiece. Traditional input interfaces are limited in the sense that they lack a direct connection with the workpiece, forcing the user to translate information gathered from the workpiece before it can be input into the computer. A similar disconnect also exists in the realm of output from the computer. On one extreme, the screen as an output interface forces the user to interpret and translate information conveyed graphically to the context of the workpiece at hand. On the other extreme, devices like CNC machines and 3D printers lack a way for the user to engage with the fabrication and to iteratively change design parameters in realtime. In this work, I present, two handtools that build on the philosophy of Free-D ([1] and [2]), a smart milling tool recently developed in our research group. to create a similar interface between Computer Aided Design and the physical workpiece, in entirely different application domains. The two handtools are BoardLab and Nishanchi. BoardLab is a smart, context-aware oscilloscope probe that can be used to dynamically search for just-in-time information on electronic circuit board design data and to automatically annotate the design data with measurements and test data. Nishanchi is a handheld inkjet printer and 3D digitizer that can be used to print raster graphics on non-conformable surfaces.

As more libraries embrace the term 'information commons' to name services and symbolise their mission, this paper explores the meaning of the concept in Australia and the US. The public library as we know it was founded on principles of providing free access to all. This is now threatened by the growth of information as commodity, and has led many to question the controls and costs of information in society. This paper examines threats that emerge from commercialisation, legislation, funding, and the changing role of libraries. The responses to these threats by libraries, individuals and organisations are detailed. Projects and alternative models that aim to protect the information commons are discussed. This paper asks if libraries should be political about this issue, and what the consequences of such action may be on funding, intellectual freedom, trust and communities.
What steps can librarians take to ensure access to information for all individuals in the future? Do the information commons represent a new direction for librarianship, or a renewed emphasis on traditional values?

Johnson, Blake Dennis. "Enabling Optimizations Through Demodularization." BYU ScholarsArchive, 2016. https://scholarsarchive.byu.edu/etd/5722.
Full textAbstract:
Programmers want to write modular programs to increase maintainability and create abstractions, but modularity hampers optimizations, especially when modules are compiled separately or written in different languages. In languages with syntactic extension capabilities, each module in a program can be written in a separate language, and the module system must ensure that the modules interoperate correctly. In Racket, the module system ensures this by separating module code into phases for runtime and compile-time and allowing phased imports and exports inside modules. We present an algorithm, called demodularization, that combines all executable code from a phased modular program into a single module that can then be optimized as a whole program. The demodularized programs have the same behavior as their modular counterparts but are easier to optimize. We show that programs maintain their meaning through an operational semantics of the demodularization process and verify that performance increases by comparing modular Racket programs to the equivalent demodularized and optimized programs. We use the existing Racket optimizer to optimize the demodularized programs by decompiling them into an intermediate form that the optimizer uses. We also demonstrate a dead code elimination optimization that dramatically reduces the file size of demodularized Racket programs.

Full textAbstract:
Future spacecraft missions are trending towards the use of distributed systems or fractionated spacecraft. Initiatives such as DARPA's System F6 are encouraging the satellite community to explore the realm of collaborative spacecraft teams in order to achieve lower cost, lower risk, and greater data value over the conventional monoliths in LEO today. Extensive research has been and is being conducted indicating the advantages of distributed spacecraft systems in terms of both capability and cost. Enabling collaborative behaviors among teams or formations of pico-satellites requires technology development in several subsystem areas including attitude determination and control subsystems, orbit determination and maintenance capabilities, as well as a means to maintain accurate knowledge of team members' position and attitude. All of these technology developments desire improvements (more specifically, decreases) in mass and power requirements in order to fit on pico-satellite platforms such as the CubeSat.
In this thesis a solution for the last technology development area aforementioned is presented. Accurate knowledge of each spacecraft's state in a formation, beyond improving collision avoidance, provides a means to best schedule sensor data gathering, thereby increasing power budget efficiency. Our solution is composed of multiple software and hardware components. First, finely-tuned flight system software for the maintaining of state knowledge through equations of motion propagation is developed. Additional software, including an extended Kalman filter implementation, and commercially available hardware components provide a means for on-board determination of both orbit and attitude. Lastly, an inter-satellite communication message structure and protocol enable the updating of position and attitude, as required, among team members. This messaging structure additionally provides a means for payload sensor and telemetry data sharing. In order to satisfy the needs of many different missions, the software has the flexibility to vary the limits of accuracy on the knowledge of team member position, velocity, and attitude. Such flexibility provides power savings for simpler applications while still enabling missions with the need of finer accuracy knowledge of the distributed team's state.
Simulation results are presented indicating the accuracy and efficiency of formation structure knowledge through incorporation of the described solution. More importantly, results indicate the collaborative module's ability to maintain formation knowledge within bounds prescribed by a user. Simulation has included hardware-in-the-loop setups utilizing an S-band transceiver. Two "satellites" (computers setup with S-band transceivers and running the software components of the collaborative module) are provided GPS inputs comparable to the outputs provided from commercial hardware; this partial hardware-in-the-loop setup demonstrates the overall capabilities of the collaborative module.
Details on each component of the module are provided. Although the module is designed with the 3U CubeSat framework as the initial demonstration platform, it is easily extendable onto other small satellite platforms. By using this collaborative module as a base, future work can build upon it with attitude control, orbit or formation control, and additional capabilities with the end goal of achieving autonomous clusters of small spacecraft.

In this thesis, we examine algorithms for content selection and information presentation that enable browsing as an information-seeking strategy. Our hypothesis is that users who wish to explore the contents of a particular domain might not be satisfied with traditional spoken dialogue systems, in which focal information is not described until a small number of the records comprising the domain are identified through a constraint-elicitation process. Specifically, we hypothesized that users would prefer responses in the form of incremental summaries of the focal information.

A strategic, technical, and organizational examination of the customer enabling effort at Intel Corporation was undertaken. The context of this study was the launch of the first boxed mobile processor in the company's history. The technical component of the work consisted of the design and development of a thermal solution to complement the boxed processor. The organizational component involved an examination of the way the team was structured to execute the project. The strategic component looked at the effect of the enabling effort on the mobile computing industry at large. Thermal solutions that met the technical specifications of the boxed mobile processor were successfully designed and prototyped. The implication of a specific thermal solution design on the level of standardization of the notebook computer platform is discussed. The conclusion is that the level of standardization in the industry is already high and is unlikely to be influenced by the boxed mobile processor. Tactics for organizational structure design are suggested for future project staffing.

The present work looks into the question of optimizing the performance of product launch decisions-in particular, the decisions of product development duration and manufacturing ramp-up. It presents an innovative model for measuring product launch performance and optimizing the decisions by integrating a design structure matrix model for product development, a technical cost model for manufacturing, and revenue and warranty models for customer reaction to product quality into one model using net revenue as a metric. The model shows that overlooking the interactions between product development and manufacturing leads to suboptimal decisions. Furthermore, it points out that product quality is apparently the most important driver for product launch performance and that the effects of product launch decisions on resulting product quality need to be considered. Results from case studies demonstrate that improving firm's tactical strategies will help shorten product launch and improve its performance, while factors such as low reputation or high product failure rate will require lengthening product launch to minimize their impacts. Finally, the model results are analyzed to yield direction for firms relative to strategies that can be implemented to improve product launch performance. The most effective strategy is one that improves the PD capability (higher ability to find and fix problems) and the second most effective is to improve problem solving in manufacturing ramp-up.

Stories are an essential piece of human intelligence. They exist in countless forms and varieties seamlessly integrated into every facet of our lives. Stories fuel human understanding and our explanations of the world. Narrative acts as a Swiss army knife, simultaneously facilitating the transfer of knowledge, culture and beliefs while also powering our high level mental faculties. If we are to develop artificial intelligence with the cognitive capacities of humans, our systems must not only be able to understand stories but also to incorporate them into the thought process as humans do. In order to work towards the goal of computational story understanding, I developed a novel story comparison method. The techniques I present in this thesis enable efficient and effective story comparison through story alignment. My algorithms, implemented into the Genesis system, allow the comparison and combination of stories which is a step towards enabling imagination in artificial intelligence. This capability is made possible by reducing the runtime of a previously intractable computational problem to polynomial time. In the course of this research, these algorithms have been applied to a variety of story analysis problems. By comparing short, 10 sentence summaries of the Tet Offensive and the Yom Kippur War, the system predicts information omitted from both stories. In the analysis of a brief synopsis of Shakespeare's Macbeth, my algorithm is able to correctly match actors and events between two different variations of the tale by cutting down a search space of over 10³⁰ nodes to a mere 546 nodes. My techniques also demonstrate promise as a component of a larger video analysis system. The story alignment capabilities are used to fill in missing gaps in descriptions of videos, corresponding to missing video data, by comparing video feeds to an existing video corpus.

Full textAbstract:
User space software allows developers to customize applications beyond the limits of the privileged operating system. In this dissertation, we extend this concept to the hardware in the system, providing applications with the ability to define secure hardware; effectively enabling hardware to be treated as a user space resource. This addresses a significant challenge facing industry today, which has an increasing need for secure hardware. With the ever increasing leaks of private data, increasing use of a variety of computing platforms controlled by third parties, and increasing sophistication of attacks, secure hardware, now more than ever, is needed to provide protections we need. However, the current ecosystem of secure hardware is fractured and limited. Developers are left with few choices of platforms to implement their applications and oftentimes the choices don’t fully meet their needs. Instead of relying on manufacturers to make the correct design decisions and ensuring that these platforms are implemented correctly, we enable applications to define the exact secure hardware that it needs to protect itself and its data.
This vision leverages the emergence of programmable hardware, specifically FPGAs, to serve as the basis of user space secure hardware. The challenges of this, however, are that (i) sharing of FPGA resources among multiple applications is not currently practical, and (ii) the reprogrammability of FPGAs compromises the security properties of secure hardware. We address these challenges by introducing two systems, Cloud RTR and Software Defined Secure Hardware, which individually solve each challenge, and then combine these solutions together to realize the complete vision. Cloud RTR solves the first challenge by leveraging cloud compilation to allow for an FPGA to be shared between applications, making hardware into a user space resource. SDSHW solves the second challenge by introducing a self-provisioning system that allows for an FPGA to provisioned into a secure state, allowing for secure hardware to be run in an FPGA. We then combine these two systems to implement the user space hardware provided by Cloud RTR on the secure platform provided by SDSHW, which provides our vision of user space secure hardware.

Full textAbstract:
Hardware and software complexity of future critical real-time systems challenges the scalability of traditional timing analysis methods. Measurement-Based Probabilistic Timing Analysis (MBPTA) has recently emerged as an industrially-viable alternative technique to deal with complex hardware/software. Yet, MBPTA requires certain timing properties in the system under analysis that are not satisfied in conventional systems. In this thesis, we introduce, for the first time, hardware and software solutions to satisfy those requirements as well as to improve MBPTA applicability. We focus on one of the hardware resources with highest impact on both average performance and Worst-Case Execution Time (WCET) in current real-time platforms, the cache. In this line, the contributions of this thesis follow three different axes: hardware solutions and software solutions to enable MBPTA, and MBPTA analysis enhancements in systems featuring caches.
At hardware level, we set the foundations of MBPTA-compliant processor designs, and define efficient time-randomised cache designs for single- and multi-level hierarchies of arbitrary complexity, including unified caches, which can be time-analysed for the first time.
We propose three new software randomisation approaches (one dynamic and two static variants) to control, in an MBPTA-compliant manner, the cache jitter in Commercial off-the-shelf (COTS) processors in real-time systems. To that end, all variants randomly vary the location of programs' code and data in memory across runs, to achieve probabilistic timing properties similar to those achieved with customised hardware cache designs.
We propose a novel method to estimate the WCET of a program using MBPTA, without requiring the end-user to identify worst-case paths and inputs, improving its applicability in industry. We also introduce Probabilistic Timing Composability, which allows Integrated Systems to reduce their WCET in the presence of time-randomised caches. With the above contributions, this thesis pushes the limits in the use of complex real-time embedded processor designs equipped with caches and paves the way towards the industrialisation of MBPTA technology.La complejidad de hardware y software de los sistemas críticos del futuro desafía la escalabilidad de los métodos tradicionales de análisis temporal. El análisis temporal probabilístico basado en medidas (MBPTA) ha aparecido últimamente como una solución viable alternativa para la industria, para manejar hardware/software complejo. Sin embargo, MBPTA requiere ciertas propiedades de tiempo en el sistema bajo análisis que no satisfacen los sistemas convencionales. En esta tesis introducimos, por primera vez, soluciones hardware y software para satisfacer estos requisitos como también mejorar la aplicabilidad de MBPTA. Nos centramos en uno de los recursos hardware con el máximo impacto en el rendimiento medio y el peor caso del tiempo de ejecución (WCET) en plataformas actuales de tiempo real, la cache. En esta línea, las contribuciones de esta tesis siguen 3 ejes distintos: soluciones hardware y soluciones software para habilitar MBPTA, y mejoras de el análisis MBPTA en sistemas usado caches. A nivel de hardware, creamos las bases del diseño de un procesador compatible con MBPTA, y definimos diseños de cache con tiempo aleatorio para jerarquías de memoria con uno y múltiples niveles de cualquier complejidad, incluso caches unificadas, las cuales pueden ser analizadas temporalmente por primera vez. Proponemos tres nuevos enfoques de aleatorización de software (uno dinámico y dos variedades estáticas) para manejar, en una manera compatible con MBPTA, la variabilidad del tiempo (jitter) de la cache en procesadores comerciales comunes en el mercado (COTS) en sistemas de tiempo real. Por eso, todas nuestras propuestas varían aleatoriamente la posición del código y de los datos del programa en la memoria entre ejecuciones del mismo, para conseguir propiedades de tiempo aleatorias, similares a las logradas con diseños hardware personalizados. Proponemos un nuevo método para estimar el WCET de un programa usando MBPTA, sin requerir que el usuario dentifique los caminos y las entradas de programa del peor caso, mejorando así la aplicabilidad de MBPTA en la industria. Además, introducimos la composabilidad de tiempo probabilística, que permite a los sistemas integrados reducir su WCET cuando usan caches de tiempo aleatorio. Con estas contribuciones, esta tesis empuja los limites en el uso de diseños complejos de procesadores empotrados en sistemas de tiempo real equipados con caches y prepara el terreno para la industrialización de la tecnología MBPTA.

Full textAbstract:
In recent years there have been tremendous advances in our ability to rapidly and cost-effectively sequence DNA. This has revolutionized the fields of genetics and biology, leading to a deeper understanding of the molecular events in life processes. The rapid advances have enormously expanded sequencing opportunities and applications, but also imposed heavy strains on steps prior to sequencing, as well as the subsequent handling and analysis of the massive amounts of sequence data that are generated, in order to exploit the full capacity of these novel platforms. The work presented in this thesis (based on six appended papers) has contributed to balancing the sequencing process by developing techniques to accelerate the rate-limiting steps prior to sequencing, facilitating sequence data analysis and applying the novel techniques to address biological questions. Papers I and II describe techniques to eliminate expensive and time-consuming preparatory steps through automating library preparation procedures prior to sequencing. The automated procedures were benchmarked against standard manual procedures and were found to substantially increase throughput while maintaining high reproducibility. In Paper III, a novel algorithm for fast classification of sequences in complex datasets is described. The algorithm was first optimized and validated using a synthetic metagenome dataset and then shown to enable faster analysis of an experimental metagenome dataset than conventional long-read aligners, with similar accuracy. Paper IV, presents an investigation of the molecular effects on the p53 gene of exposing human skin to sunlight during the course of a summer holiday. There was evidence of previously accumulated persistent p53 mutations in 14% of all epidermal cells. Most of these mutations are likely to be passenger events, as the affected cell compartments showed no apparent growth advantage. An annual rate of 35,000 novel sun-induced persistent p53 mutations was estimated to occur in sun-exposed skin of a human individual. Paper V, assesses the effect of using RNA obtained from whole cell extracts (total RNA) or cytoplasmic RNA on quantifying transcripts detected in subsequent analysis. Overall, more differentially detected genes were identified when using the cytoplasmic RNA. The major reason for this is related to the reduced complexity of cytoplasmic RNA, but also apparently due (at least partly) to the nuclear retention of transcripts with long, structured 5’- and 3’-untranslated regions or long protein coding sequences. The last paper, VI, describes whole-genome sequencing of a large, consanguineous family with a history of Leber hereditary optic neuropathy (LHON) on the maternal side. The analysis identified new candidate genes, which could be important in the aetiology of LHON. However, these candidates require further validation before any firm conclusions can be drawn regarding their contribution to the manifestation of LHON.QC 20111115

Full textAbstract:
User-generated content, UGC, is a modern topic today and refers to media and creative works created by Internet users and posted on the Internet. More and more application developers wants to offer sharing functionalities in their applications and on their websites. The alternatives of doing so today are to use UGC platforms API, like Facebook and Twitter, to upload the content to that specific platform or to implement the framework ShareKit that enables the user to share their content on multiple social networks and platforms. If the application developer wants the user to upload the content to their own platform they have to implement the sharing functionality themselves. This thesis covers the development of a framework that enables user-generated content to be uploaded to the application owner’s choice of destination whether it is their own platform or someone else’s. By exploring the meaning of user-generated content, why people want to share and existing sharing applications, information as well as inspirations was gathered and used to design a prototype that was user-tested, redesigned and implemented. The result was a prototype of a framework implemented for the iPhone that provides an easy way for users to add, edit, rearrange and upload different types of content. User-generated content will increase in the future and the mobile part of UGC will be more and more important. People are going to want to be able to express themselves wherever they are. This makes the future for this framework bright since it makes it easy for application developers to enable sharing of user-generated content in their applications.

Full textAbstract:
Public space, where ordinary situations and everyday life takes place, is a concept that has gone from being ignored to becoming the core of urban development. As the interest of public space is increasing, so does the critique. A critique that in Kista criticizes public space for being neglected, segregated and scary. Nevertheless, Kista is standing before several urban renewal projects aiming to be a place of mixed functions and vibrancy. However, these projects are both time-consuming and complex and will not be able to address the issues within the nearest future. By introducing temporary use of public space, ideals such as placemaking and temporary urbanism may deal with the amount of time being consumed during the planning processes of formulation, approval, adaption and implementation. It is done so by activating space through meanwhile usage. By studying places, functions and actors in Kista, the aim is to develop a method to initiate and implement the concept of temporary use of space, in accordance to the Swedish planning system. Through a literature review, a city’s function is being analyzed, definitions of public space identified and urbans ideals/ theories explored. Furthermore, two urban renewal projects are being studied, where strategic structures of how to develop temporary initiatives is analyzed. From the literature review follows a case study where interviews and observations are being conducted to gain local knowledge and professional expertise. There are both general drivers and specific features found in Kista arguing for temporary use of space, which results in a strategy and a process. The strategy is of a comprehensive approach aiming to initiate the concept of temporary use while the process is about how to implement temporary activities. To initiate and implement temporary use of space several strategic structures are suggested. The study suggests an early implementation within a larger urban renewal project, developed together with a vision and municipal plan and program. The method should be of a top-down structure, led by Kista Science City and developed by the City of Stockholm and real estate developers in Kista. The community should act as co-creators during the development and implementation of temporary activities. Space chosen for temporary used should be done so with care, in relation to knowledge of what attracts people and preconditions in Kista. The structure of the process needs to be dynamic, giving room for changes and improvements.

Full textAbstract:
Continuous improvements to the state of the art have made it easier to create, send and receive vast quantities of video over the Internet. Catalysed by these developments, video is now the largest, and fastest growing type of traffic on modern IP networks. In 2015, video was responsible for 70% of all traffic on the Internet, with an compound annual growth rate of 27%. On the other hand, concerns about the growing energy consumption of ICT in general, continue to rise. It is not surprising that there is a significant energy cost associated with these extensive video usage patterns. In this thesis, I examine the energy consumption of typical video configurations during decoding (playback) and encoding through empirical measurements on an experimental test-bed. I then make extrapolations to a global scale to show the opportunity for significant energy savings, achievable by simple modifications to these video configurations. Based on insights gained from these measurements, I propose a novel, energy-aware Quality of Experience (QoE) metric for digital video - the Energy - Video Quality Index (EnVI). Then, I present and evaluate vEQ-benchmark, a benchmarking and measurement tool for the purpose of generating EnVI scores. The tool enables fine-grained resource-usage analyses on video playback systems, and facilitates the creation of statistical models of power usage for these systems. I propose GreenDASH, an energy-aware extension of the existing Dynamic Adaptive Streaming over HTTP standard (DASH). GreenDASH incorporates relevant energy-usage and video quality information into the existing standard. It could enable dynamic, energy-aware adaptation for video in response to energy-usage and user ‘green' preferences. I also evaluate the subjective perception of such energy-aware, adaptive video streaming by means of a user study featuring 36 participants. I examine how video may be adapted to save energy without a significant impact on the Quality of Experience of these users. In summary, this thesis highlights the significant opportunities for energy savings if Internet users gain an awareness about their energy usage, and presents a technical discussion how this can be achieved by straightforward extensions to the current state of the art.

Full textAbstract:
The thesis work is centered on five objectives. These objectives are among the main factors in the field of electronic information display technologies. They are namely display optical efficiency, crosstalk, resolution, power consumption and switchable 2D/3D capability. The thesis findings and the different levels of success are covered in detail in chapters 4 through chapter 8. They are then summarized in discussion and conclusion chapter using measurable quantities in tabular format. Specifically, with respect to optical efficiency three different solutions were applied. The first raised optical efficiency by 60%. The second solution raised optical efficiency to 90%. The third solution eliminated the need for backlighting altogether as well as remove pixel circuitry from optical light path. With respect to image crosstalk, two solutions were applied. One method reduced crosstalk by 51% while the other method eliminated crosstalk to zero percent in the viewing zones. With respect to resolution two methods were applied. One method increased 3D display resolution by limiting the reduction of the native display resolution by only half regardless of the number of concurrent 3D viewers. The other method increased display resolution 900%. With respect to power consumption two methods were applied. The first method eliminated the need for backlighting and also reduced the number of thin film transistors [TFTs] needed by 60% for the same display resolution. The second method increased display brightness by 60% without increasing power consumption. Finally with respect to 2D/3D switchable display an optical module was designed that successfully enable a conventional 2D display to become a switchable 2D/3D display.

Full textAbstract:
For any practical implementation of chip design, there needs to be a hardware platform available for the purpose of prototyping and implementation of FPGA-based programs, whether they are written in VHDL or Verilog. Communication between the platform and a computer is a useful feature of many hardware solutions as it allows for the capability of regular data transmission between the two devices. Furthermore, the ability to communicate between the platform and a computer at high-speeds requires a specially constructed interface, one that can be modified by the designer at their choosing.
There are a number of commercial packages which provide a hardware platform to perform this task, however there are drawbacks to many of the available options. Some may require special hardware to connect to a computer using proprietary connectors or boards, which increases the cost and reduces the flexibility of any solution. Other options may have limited access to the internal structure of the interface, limiting the ability of the developer to modify the interface to suit their needs. There may be an extra cost to provide the code to the interface, separate from the board, which can also tax design budgets.
This dissertation provides a solution in the form of a Gigabit Ethernet connection with a custom IP/network layer written in VHDL to facilitate the connection. With an increasing number of IP-enabled devices available such as IPTV and set top boxes, the ability to link hardware using Ethernet is very useful and so the development of a lean and capable network layer was considered a suitable focus for the project. The overall goal has been to provide an interface which is cheap, open, robust and efficient, retaining the flexibility a developer might require to modify the code to their needs.
After covering some basic background information about the project, the dissertation looks at the requirements of the board and interface, as well as the alternative interface solutions which were looked at before deciding on Gigabit Ethernet. The protocols used in Ethernet are then covered, with both an explanation of the structure of each and their relevance to the implementation. The Finite State Machines which control operation of the interface are covered in depth, with an explanation of their inter-connectivity to each other and how they fit in the data-flow between the computer and the board. Error correction and reliability is discussed, as well as any remaining components critical to the operation of the interface.
Pipelining, the method of design which provides the speed required for Gigabit Ethernet, is covered along with the extra speed optimisation techniques used in the design such as RAM swinging buffers. Testing and synthesis are covered which ensure the design is as robust as possible, both in simulations and in real-world applications. The final design was implemented on a Xilinx Spartan 3 FPGA (XC3S5000-5FG900C) and capable of a maximum speed of 128.287 MHz, which is more than enough to satisfy the requirements of Gigabit Ethernet under a variety of network conditions. The interface code occupies 1,166 slices of logic on the FPGA (3% of the total amount of logic available), making it sufficiently compact to run large projects on the same chip. The core was tested on physical hardware and performed correctly at real line Gigabit speeds. Configuration of the computer along with the method of connecting to the board and transferring data is mentioned, with explanation of the code run on the computer to make this possible. Finally, the dissertation provides an example application through the use of JPEG2000 image compression/decompression.

Approved for public release; distribution is unlimited.Computer networks of today are based predominantly on the TCP/IP protocol suite that provides best effort service. The current IP protocol excels in its simplicity and network fault tolerance. The way it implements this simplicity and fault tolerance, however, limits the protocol's ability to provide a guaranteed Quality of Service (QoS). A first Step in providing this QoS is to incorporate the concept of flow based routing. This thesis describes an implementation of the Server and Agent based Active network Management (SAAM) system architecture that incorporates flow based routing. The architecture contains servers that maintain a database that is used for assigning each flow to a path that will provide the needed QoS.

Full textAbstract:
The construction industry is highly fragmented, consisting of a large number of very small companies that come together as members of non-collocated teams to complete building projects, and who subsequently may never work together again. The industry still faces various challenges in terms of human and organisational issues. The Virtual Enterprise (VE), and other variations of the paradigm, relies on networking organisations as elements forming an alliance or aggregation towards some specific purpose or opportunity. Rather than the VE being a completely new organisational form, the construction industry has adopted many of its characteristics in its modus operandi for some considerable time. The construction industry does not operate effectively as a VE and in consequence faces many problems. These problems could be addressed by the development of ICT solutions geared towards digitally enabling the VE. The success of collaborative work, and the successful design and uptake of such ICT tools to support that work relies not merely on the introduction of different technologies, however, but also on critically analysing `human' aspects of organisation. Using applied research and drawing on a central case study in which a VE solution was developed, tested and evaluated in the context of `real world' scenarios, the thesis addresses the socio-organisational aspects of technological intervention and seeks to answer four research questions dealing with the above. The main results include recognition that whilst ICT are advanced enough to offer adapted solutions to digitally enabling the construction VE, the technology alone is not sufficient. The construction industry is not yet ready to move to an approach employing latest ICT development, due to the need to manage human and organisational issues central to technological intervention. The thesis finally offers business recommendations highlighting and mapping the critical human and organisational decisions that need to be considered.

Scientific data does not exist on the Web in the same way as the written word; reviews, media, wikis, social networks, and blogs all contribute to the interconnected nature of ordinary language on the Web. Network effects create additional value from seemingly minor contributions to the Web. But nothing such as this exists for scientific data. Simply put, within the Open Web Platform, we cannot currently turn and apply similar mechanisms for scientific work without great effort. Thus, the Web has not so far enabled Science as well as it has enabled dissemination and interconnection for the written word: to truly enable Science on the Web, we must endeavor to make data and its semantics first-class Web constituents. This thesis focuses on solving this problem by enabling scientific data to exist on the Web in such a way that it can be processed both as viewable content and consumed data. Starting from the principles on which the Web has so far thrived, we propose solutions to enable complex data exchanges while preserving the Web as it stands. We introduce the Partition Annotate Name (PAN) methodology, which relies upon embracing the core architectural principles of the Web: name things with URIs; process common data formats; use common rules under a shared contract between publisher, developer, and consumer.

Full textAbstract:
This thesis is concerned with the lived experience of dyslexic actors. It explores the role of performance in constructing dyslexic identities, actors' relationships to written and verbal language, the ways in which this might impact on their acting process and implications for teaching practice. Research into dyslexia and acting practice is needed in light of the growing interest in cognition within the field of performance theory, the legislative framework surrounding dyslexia, implications for policy and practice and the numbers of professional actors with dyslexia. The methodology draws on a range of paradigms, namely phenomenology, embodied cognition and disability theory and adopts a mixed methods approach, in order to explore the complex nature of dyslexia and address a range of research questions. The research finds that the research participants have a different intentional relationship to language and linear sequencing. Certain training and acting experiences have given them a different experience of being in the world, creating positive dyslexic identities and body images. Disabling training approaches predicated on linear-sequencing and literacy, are the antithesis to methods which utilise non-linear, holistic and non-verbal processing. Actors manipulate the physical environment and the objects in it, to control what is otherwise a chaotic environment. A number of examples of inclusive practice and support models exist, but evidence of disabling practices remain. The research has potential policy and pedagogical implications both for actor training institutions and the industry. It also has implications for those dyslexic learners who are not professional actors, as acting may have cognitive benefits for such people and encourage positive dyslexic identities. There are broader implications relating to theatre and performance theory as a discipline, as models of neuro-diversity (such as dyslexia) can enhance current performance theory. This research may also encourage dyslexic actors not to merely survive but to thrive in the acting profession.

Today's virtual reality (VR) headsets require a cable connection to a PC or game console. This cable significantly limits the player's mobility and, hence, her VR experience. The high data rate requirement of this link (multiple Gbps) precludes its replacement by WiFi. Thus, in this thesis, we focus on using mmWave technology to deliver multi-Gbps wireless communication between VR headsets and their game consoles. We address the two key problems that prevent existing mmWave links from being used in VR systems. First, mmWave signals suffer from a blockage problem, i.e., they operate mainly in line-of-sight and can be blocked by simple obstacles such as the player lifting her hand in front of the headset. Second, mmWave radios use highly directional antennas with very narrow beams; they work only when the transmitter's beam is aligned with the receiver's beam. Any small movement of the headset can break the alignment and stall the data stream. We present MoVR, a novel system that allows mmWave links to sustain high data rates even in the presence of a blockage and mobility. MoVR does this by introducing a smart mmWave mirror and leveraging VR headset tracking information. We implement MoVR and empirically demonstrate its performance using an HTC VR headset.

Sketching, although deceptively simple and seemingly primitive, is a powerful paradigm for designing and understanding many types of engineering systems. Many problem domains, such as designing electrical circuits, developing flow charts, and modeling simple mechanical devices, rely heavily on the ability to produce sketches efficiently in order to bring out the most salient features. Engineers working in these domains usually rely on pen and paper to generate their design sketches. They do this because more advanced technologies (such as notebook computers) are often unavailable, hard to learn, or cumbersome. It is important for engineers to collaborate with their colleagues while working on their sketches. Unfortunately, collaboration on sketches that exist only as pen and paper often proves to be tedious, requiring a minimum of a fax machine and scanner. Engineers could benefit from a more efficient means of collaboration when dealing with pen and paper sketches. The technology exists to improve the current situation and make pen and paper sketches a more effective medium for collaborative design. This thesis presents an implementation of a system that achieves three goals. First, the system allows two users to collaborate on the production of a sketch in much the same way they would collaborate when composing a document (with one user composing a sketch, then accepting or rejecting the changes of his collaborator).
(cont.) Second, it allows users to watch a collaborator's additions play in real time, like watching a movie. And finally, it links the sketch recognition and simulation software developed by the Design Rationale Group at MIT with a simple pen and paper interface, allowing engineers to run simulations of their design sketches. These goals are achieved by using a commercial pen produced by the Anoto Group that is capable of storing the strokes it draws. In essence, the user creates both a hard and soft copy of the sketch simultaneously, and can share the soft copy with any collaborator. Using this model of production, sketches can be collaboratively generated, edited, and reviewed quickly and easily, all using only a pen, paper, and a standard printer.

Manufacturing organizations around the world strive to improve processes with varying degrees of realization. There is no right way or latest and greatest process that can guarantee success, therefore the approach, and not necessarily the process, is critical. Since every process improvement project is different, using the systems thinking approach decreases the risk of failure as the implementer(s) is/are more aware of critical items on the fringe which might otherwise be neglected. Process metrics are vital for many reasons including motivating employees, determining the level of need for process improvement, and evaluating the outcome of a process improvement project. When evaluating whether a project should be pursued, the expected results on the subsystem and other subsystems should be estimated and tied to the highest level metric, which ultimately should equate to bottom line impact. This evaluation technique ensures a positive impact on the entire system, rather than producing only a subsystem optimum. A subsystem metric indicates a project's success through the use of a hypothesis test. This usage requires that the subsystem metric, which will be used to measure a process improvement, must be stable before initiating the project.
(cont.) The individual, team, and organization all play a vital role in a company embracing systems thinking. Individuals and teams need to keep an open mind to issues outside the focus department and accept and encourage involvement of cross-functional representatives on process improvement teams. An organization where systems thinking is integral becomes a learning organization and has a higher percentage of successful projects through a systematic evaluation and approach to projects. To maintain the systems thinking culture, an organization as a whole must encourage the hiring of individuals with varied experiences and who believe in systems thinking.

This dissertation presents a framework which supports a group-based exploratory approach to learning and integrates 3D gaming methods and technologies with an institutional learning environment. This provides learners with anytime-anywhere access to interactive learning materials, thereby supporting a self paced and personalised approach to learning. A simulation environment based on real world data has been developed, with a computer games methodology adopted as the means by which users are able to progress through the system. Within a virtual setting users, or groups of users, are faced with a series of dynamic challenges with which they engage until such time as they have shown a certain level of competence. Once a series of domain specific objectives have been met, users are able to progress forward to the next level of the simulation. Through the use of Internet and 3D visualisation technologies, an excavation simulator has been developed which provides the opportunity for students to engage in a virtual excavation project, applying their knowledge and reflecting on the outcomes of their decisions. The excavation simulator enhances the student learning experience by providing opportunities for students to engage with the archaeological excavation process in a customisable, virtual environment. Not only does this provide students with an opportunity to put some of the theories they are familiar with into practice, but it also allows for archaeology courses to place a greater emphasis on the practical application of knowledge that occurs during the excavation process. Laconia Acropolis Virtual Archaeology (LAVA) is a co-operative exploratory learning environment that addresses the need for students to engage with archaeological excavation scenarios. By leveraging the immersive nature of gaming technologies and 3D multi-user virtual environments (MUVEs), LAVA facilitates the adoption of exploratory learning practices in environments which have previously been inaccessible due to barriers of space, time or cost.

Full textAbstract:
The confinement and control of atomic clouds, at temperatures measured in nanokelvin, has become a valuable tool for physicists. As a source of new physics, development ofcooling techniques has led to innovative new ways to probe the nature of reality. Of particular note are experiments carried out on new and exotic states of matter such as the Bose-Einstein condensate, unseen before the advent of these techniques. Likewise,the potential for applications outside of the lab is extensive and encompasses navigation,timekeeping, quantum communication and quantum computing. Manipulating cold atoms in the presence of a so-called ‘atom chip’ (a millimetre-scale electronic device) is currently considered the future of miniaturising these experiments and measurements,but since they still require precisely locked and stabilised lasers and predominantly must take place in the ultra-high vacuum regime, quantum control relies on an extensive and well-established infrastructure of optics, electronics, vacuum chambers and pumps. This encumbrance has slowed down the transition from chip-in-a-lab experiments to lab-on-a-chip technologies. This thesis is an account of work carried out in the development of enabling technologies which will accelerate this transition, including details of prototype devices made using established semiconductor and MEMS planar fabrication techniques. The construction and testing of an apparatus for anodically and eutectically bonding die-scale samples in ultra-high vacuum is described, along with an analysis and characterisation of some of its products.
