A theory of the viewer experience of interactive television

This research addresses a gap in knowledge of how and why people might use new technologies to interact with television. The emerging medium of interactive television (iTV) is qualitatively different from other screen-based interaction paradigms, including personal computers, console games, and internet-based video services. This qualitative difference means we cannot assume that human computer interaction (HCI) knowledge and guidelines from these other domains can be applied to television use. If iTV is to succeed, it will need to find interaction paradigms appropriate to the television viewing context. It has been argued that sound theory is a prerequisite for the growth of the discipline of HCI, but that existing HCI theory tends to be too specific for broad application or reuse. HCI theories tend to be borrowed from other disciplines, such as cognitive science, and often prove too complex to be tractable by user interface designers. Hence the call for the development of HCI theory integrating models from related human sciences, formulated to be tractable by designer practitioners. In response to this call, this thesis develops an integrative theory of the user experience of iTV formulated for the use of iTV designers. A constructivist Grounded Theory methodology was used to derive the theory from data. The theory is based on data collected from: i) three iTV projects investigating interaction approaches for Children’s content, for News programs, and for Messaging applications in a remote western Australian desert community; ii) a detailed analysis of iTV interaction, iii) reviews of relevant literature from HCI, Media Studies and Psychology disciplines. A purpose built database contained more than 1700 discrete theory-related notes, including 94 identified themes, all interlinked by more than 3700 relationships. Twenty five categories were developed from patterns identified in the data through an abductive and inductive process of clustering, sorting, and abstraction; directed by criteria of explanatory power, elegance, coherence, clarity, and precision; with constant comparison to the data. The resultant theory was validated according to its ability to generate hypotheses relevant and useful to iTV design practitioners, and its ability to augment pre-existing design guidelines.
Progress in Applied Nonlinear Dynamics: Welcome to NDPLS Volume 8

A cleaning device having particular utility for cleaning a golf ball is disclosed. A holding element includes a bottom, an upstanding wall, and an inwardly directed lip which forms an opening. A cleaning element is held within the device such that it is easily engaged by inserting a portion of the golf ball through the opening. The lip extends inwardly by a distance such that, when the cleaning device is in a generally vertical orientation, the lip, wall, and bottom form a reservoir to prevent the leakage of a cleaning fluid. The cleaning fluid is preferably water. The cleaning element is made of synthetic material and includes a woven pad backing and upwardly directed filaments. The woven backing provides a plurality of cavities for holding the cleaning fluid, while the filaments provide a surface for scrubbing the portion of the golf ball. Artificial turf is the preferred material for the cleaning element.
Statistical analysis of child growth data

The study of child growth is complex. There are many clinical questions to answer but not necessarily the statistical methodology to deal with these questions. Human growth begins at conception and continues into adult life. In chapter 1 we discuss the characteristics of the growth process from conception to maturity and the purpose of growth monitoring. In chapter 2 we summarise the mathematical approaches to growth data. In chapter 3 we summarise the approaches that have been used to detect growth faltering. In this chapter we introduce the conditional gain Z-score. The data set analysed within this thesis is from the Newcastle growth and development study. In infancy we have routine weights of 3415 term infants. A sub-sample of these infants were followed-up at 7-9 years as part of a research study. These children belonged to three subgroups: cases were children that were defined as failing to thrive in infancy, controls were matched to cases and a 20% systematic sample. The school entry data of the sub-sample followed at 7-9 years were retrieved from school health records. In chapter 4 we carry out a preliminary analysis of the routine infancy weight Z-scores. The infancy data provided the opportunity to generate the correlation structure of routine weight Z-scores in infancy. In chapter 5 we develop a model for this correlation structure. In chapter 7 we explore patterns in the conditional weight gain Z-scores and also suggest some alternative criteria for identifying growth faltering in infancy. In chapters 6, 8 and 9 we analyse the anthropometric data obtained at follow-up and school entry. In childhood, the conditional gain Z-score is used to contrast height with mid-parental height and height at follow-up with height at school entry. The anthropometric data of the case and control children will be compared.

A methodology to develop a communication protocol for visualizing simulaitons in a collaborative virtual reality environment

In the technology field, simulations and collaborative virtual reality environments (CVREs) are not generally combined because it is complicated to develop large scale simulations within CVREs. The complexity of combining these two technologies in order to form a better form of visualization stems from the lack of a methodology to help derive these scalable simulations. Simulations require very complex calculations that the CVRE cannot perform as it is overloaded in calculations for the maintenance and stability of the environment itself. Since the simulation cannot be held within the CVRE, the solution is to move the simulation external to the CVRE and provide means for the CVRE and simulation to communicate so the scene within the CVRE can be updated. While this increases the performance of the simulation in the CVRE, another element is required to make the simulation scalable. Since the CVRE controls the interactions and the simulation controls the calculations and reactions, the basic structure of the this operations can be visualized as a state machine. By implementing the simulation as a state machine, if another element needs to be added to the simulation, it is a matter of implementing a new state and adding the transitions between the new state and all preexisting states. Implementing the simulation as a state machine leaves the CVRE responsible for the visualization of the simulation and provides means for the simulation and CVRE to communicate, which leads to the idea of a new developmental methodology for the visualization of large scale simulations in CVRE. This methodology will result in the ability to provide simulations in need of a visualization to be quickly and cost effectively implemented in a CVRE so that single users can visualize and interact. This methodology will not only impact those in need of simulations in the result of more simulation and training software, but also provide a better workforce equipped with decision-making tools and more widely available simulation and training software.
Managing crowdsourcing assignments

Crowdsourcing is not an outsourcing panacea to solve all problems, but it is a useful tool for business and IT managers to have in their toolbox. However, crowdsourcing does require some rethinking of traditional approaches to managing outsourcing activities, notably with regards to service-level agreements (SLAs), motivating participation, and generally “managing” the crowd. In this article, I address three aspects of the crowdsourcing phenomenon: how crowdsourcing works, how to manage it, and where one can use it.
A CONVERSATIONAL AGENT TO NAVIGATE IN VIRTUAL WORLDS

This paper describes the prototype of a spoken conversational agent embedded within a virtual reality environment. This prototype –Ulysse – accepts utterances from a user enabling him or her to navigate into relatively complex virtual worlds. The paper first describes what we can expect from such an interface in the communication quality between a user and virtual worlds. Then it describes Ulysse’s architecture which includes a speech recognition device together with a speech synthesizer. Ulysse consists in a chart parser for spoken words; a semantic analyzer; a reference resolution system; a geometric reasoner, and a dialogue manager. Ulysse has been integrated in a virtual reality environment and demonstrated.

Managing Big Data for Scientific Visualization

Many areas of endeavor have problems with big data. Some classical business applications have faced big data for some time (e.g. airline reservation systems), and newer business applications to exploit big data are under construction (e.g. data warehouses, federations of databases). While engineering and scientific visualization have also faced the problem for some time, solutions are less well developed, and common techniques are less well understood. In this section we offer some structure to understand what has been done to manage big data for engineering and scientific visualization, and to understand and go forward in areas that may prove fruitful. With this structure as backdrop, we discuss the work that has been done in management of big data, as well as our own work on demand-paged segments for fluid flow visualization.
Line Following Visual Servoing for Aerial Robots Combined with Complementary Sensors

This article addresses the problem of visual line following for aerial robotic vehicles, considering an airship as platform. Previous work showed that targets characterized by three parallel lines make possible to assure a unique pose for the aerial robot. Here, twoline targets are considered, what leaves two d.o. f. unconstrained by the visual servo control. In this case, other than visual signals provided by an onboard camera, complementary sensorial information is needed to fully control the vehicle states. The sensor suite comprises also an airspeed sensor and a sensor to measure the airship rotation around its longitudinal axis. A two-line following sensor-based scheme using an output error LQ regulator with PID structure is detailed. Simulation results, obtained by using a complete airship dynamic model, are presented.
High Throughput Reed Solomon Decoder for Ultra Wide Band

Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops, and wireless systems as well as in networking communications and magnetic and data storage systems. Continual demand for ever higher data rates makes it necessary to devise very high-speed implementations of RS decoders. This report summarizes the most recent algorithms and architectures used for implementing high-speed RS decoders. The architecture which promised to be the best in terms of area, latency, power consumption and speed was then chosen for VHDL implementation. The implementation was tested using Cadence SimVision and optimised for high speed and low area. Conclusions: A uniform comparison was drawn for various algorithms proposed in the literature. This helped in selecting the appropriate architecture for the intended application. Modified Berlekamp Massey algorithm was chosen for the VHDL implementation. Further, dual line architecture was used which is as fast as serial and has low latency as that of a parallel approach. The decoder implemented is capable of running at 200 MHz in ASIC implementation, which translates to 1.6Gbps and requires only about 12K design cells and an area of 0 . 22mm2 with CMOS12 technology. The system has a latency of only 284 cycles for RS(255,239) code. The power dissipated in the worst case is 14mW including the memory block when operating at 1Gbps data rate. c ©Koninklijke Philips Electronics N.V. 2004 iii PR-TN-2004/00933 Unclassified iv c ©Koninklijke Philips Electronics N.V. 2004 Unclassified PR-TN-2004/00933
Power Systems 2.0: Designing an Energy Information System for Microgrid Operation

In this paper we demonstrate the contribution of information systems towards a sustainable and reliable power supply. Following a Design Science approach we develop an information system for microgrid operation at a U.S. army base. Microgrids enable an improved integration of distributed renewable energy sources and increase the robustness of the overall power grid. The microgrid in this study contains extensive photovoltaic generation, the energy demand of the base, as well as energy storage. The information system we design controls and optimizes microgrid operations under uncertainty, as well as physical and organizational constraints. Using real-world data to evaluate the system, we show that it substantially increases the amount of clean photovoltaic energy that can be generated while simultaneously decreasing energy costs of the base. Thereby, we are able to improve the ecological and economic efficiency of the microgrid.
A Corrected 3D Parallel SPH Method for Simulating thePolymer Free Surface Flows Based on the XPP Model

In this work, a corrected three-dimensional smoothed particle hydrodynamics (CSPH-3D) method is proposed to simulate the polymer free surface flows in the filling process based on the eXtended Pom-Pom (XPP) model, and some complex deformation phenomena are also numerically predicted. The proposed CSPH-3D method is mainly motivated by a coupled concept that an extended kernel-gradient-corrected SPH (KGC-SPH) method is used in the interior of fluid flow and the traditional SPH (TSPH) method is used near the boundary domain. The present 3D particle method has higher accuracy and better stability than the TSPH-3D method. Meanwhile, a density diffusive term is introduced to restrain the pressure oscillations, and a new boundary treatment is proposed to deal with multi-complex-wall-boundaries, which is effective and convenient for enforcing. Moreover, the MPI parallelization means with a dynamic cells neighbor particle search method is also adopted for enhancing the computational efficiency. The advantages and ability of the present method combined with other techniques are first demonstrated by several bench tests and compared with other results. Then the filling processes confined in two type containers based on the XPP fluid are simulated using the proposed CSPH-3D method, which including the filling with two-inlets in a rectangle container and the complex filling of die casting in a ring container. Some interesting phenomena are observed for example the jet coiling and race track effect, and the shear thinning behavior of XPP fluid is also shown. Finally, the influences of macroscopic rheological parameters on the deformation of complex filling process are numerically predicted and analyzed.
Low Power Division and Square Root

of the Dissertation Low Power Division and Square Root by Alberto Nannarelli Doctor of Philosophy in Engineering University of California, Irvine, 1999 Professor Tomás Lang, Chair The general objective of our work is to develop methods to reduce the energy consumption of arithmetic modules while maintaining the delay unchanged and keeping the increase in the area to a minimum. Here, we present techniques for dividers and square root units realized in CMOS technology. The energy dissipation reduction is carried out at different levels of abstraction: from the algorithm level down to the implementation, or gate, level. We describe the use of techniques such as switching-off not active blocks, retiming, dual voltage, and equalizing the paths to reduce glitches. Also, we describe modifications in the on-the-fly conversion and rounding algorithm and in the redundant representation of the residual in order to reduce the energy dissipation. The techniques and modifications mentioned above are applied to several division and square root schemes, realized with static CMOS standard cells, for which a reduction in the energy dissipation of about 40 percent is obtained with respect to the standard implementation optimized for minimum delay. This reduction is expected to be even larger if low-voltage gates, for dual voltage implementation, are available.
CMM for Small Organizations - Level 2

This paper presents a model for software process improvement, intended for small, growing organisations. The publically available models, e.g. CMM, are not adequate for small organisations. One reason is that the number of roles proposed exceeds the number of employees. Another reason is that the responsibilities and tasks proposed are too many and rigorous, at least, in very small organisations with only a few employees. Neither is that kind of rigour needed if it is easy to get oversight of the activities because of the easy communication and organisational structure. The model described in this paper is a modified CMM, called "Dynamic CMM", applicable from the very start of an organisation and at the same time, supporting the quality and improvement activities while the organisation grows. The work behind the model is part of the research project QMSE (Quality Management for Small Enterprises), conducted at Umeå University and financially supported by NUTEK. The entire project group consisting of Jürgen Börstler, Olof Johansson, Hans Segerberg, Ola Ågren and Hans Segerstad, in addition to the authors, has participated in the development and reviewing of the document.

Value elicitation in value based software engineering

Value elicitation in VBSE is of utmost importance as the whole domain depends on values determined by SCSs. This research aims to clarify value elicitation process with all the necessary details: simplification of SCSs identification process, review and analysis of value dimensions and value elicitation techniques. After all the required analysis, Value Elicitation Framework is proposed that helps in selection and application of appropriate value elicitation technique for a given situation in the project lifecycle. In addition to this proposed framework facilitates the decision making process by introducing the concept of value into it. Validation of VEF is also done by applying the proposed framework on a software project.

World Knowledge Driving Young Readers' Comprehension Difficulties

Our goal in this project is to develop a better understanding of young readers' difficulties in comprehending text, and how those difficulties vary as a function of reader aptitudes and text genre. Therefore, we examined the effects of reading decoding abilities and world knowledge (assessed using the Woodcock-Johnson III Tests of Achievement) on 61 third-grade readers' comprehension of narrative and expository texts. The children read a narrative (445 words) and an expository (464 words) text. Comprehension of each text was assessed with 12 multiple-choice questions. Comprehension of the narrative text improved as a function of decoding ability. In contrast, expository text comprehension was driven by world knowledge. The latter result indicates that the low-knowledge children were not able to make the knowledge-based inferences required by the expository text, replicating previous work conducted with adult populations (e.g., McNamara, 2001). Potential solutions to facilitate comprehension from expository texts, such as increased text cohesion and reading strategy instruction are discussed.
Detecting and Diagnosing Grammatical Errors for Beginning Learners of German: From Learner Corpus Annotation to Constraint Satisfaction Problems.

This thesis presents a corpus of beginning learner German with a reliable error annotation scheme and an approach for detecting and diagnosing grammatical errors in learner language. A constraint-based dependency parser provides the foundation for a flexible and modular analysis of German by representing parsing as a constraint satisfaction problem. The grammar checker, Fledgling, detects and diagnoses errors using constraint relaxation with a general-purpose conflict detection algorithm. Fledgling is developed and evaluated using authentic learner productions from the learner corpus. It judges grammaticality correctly for 80% of sentences and is 82–91% accurate in determining whether a sentence contains selection, agreement, or word order errors.
