PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO<br>A Visão Computacional pode ser utilizada para capturar

dispositivos comerciais atuais de interação baseados em
gestos utilizam
equipamentos caros (dispositivos de seguimento, luvas,

o público em geral.
Este trabalho apresenta um estudo sobre a viabilidade de
utilizarmos câmeras

Mão. Em nosso
estudo consideramos que a mão humana está limpa, isto é,
sem nenhum

Consideramos
ainda que o ambiente onde ocorre a interação tem as
características de um
ambiente de trabalho normal, ou seja, sem luzes ou panos

Para avaliar a viabilidade deste mecanismo de interação,
desenvolvemos
alguns protótipos. Neles os gestos da mão e as posições
dos dedos são
utilizados para simular algumas funções presentes em
mouses e teclados, tais
como selecionar estados e objetos e definir direções e

nestes protótipos apresentamos algumas conclusões e

Current commercial
gesture-based interaction devices make use of expensive

a study on the feasibility of using Web cameras as
interaction devices based
on hand-gestures. In our study, we consider that the hand
is clean, that is, it
has no (mechanical, magnetic or optical) device. We also
consider that the
environment where the interaction takes place has the
characteristics of a
normal working place, that is, without special lights or

evaluate the feasibility of such interaction mechanism, we
have developed
some prototypes of interaction devices. In these
prototypes, hand gestures and
the position of fingers were used to simulate some mouse

functions, such as selecting states and objects, and
defining directions and

Perks, Oliver F. J. "Addressing parallel application memory consumption." Thesis, University of Warwick, 2013. http://wrap.warwick.ac.uk/58493/.
Full textAbstract:
Recent trends in computer architecture are furthering the gap between CPU capabilities and those of the memory system. The rise of multi-core processors is having a dramatic effect on memory interactions, not just with respect to performance but crucially to capacity. The slow growth of DRAM capacity, coupled with configuration limitations, is driving up the cost of memory systems as a proportion of total HPC platform cost. As a result, scientific institutions are increasingly interested in application memory consumption, and in justifying the cost associated with maintaining high memory-per-core ratios. By studying the scaling behaviour of applications, both in terms of runtime and memory consumption, we are able to demonstrate a decrease in workload efficiency in low memory environments, resulting from poor memory scalability. Current tools are lacking in performance and analytical capabilities motivating the development of a new suite of tools for capturing and analysing memory consumption in large scale parallel applications. By observing and analysing memory allocations we are able to record not only how much but more crucially where and when an application uses its memory. We use use this analysis to look at some of the key principles in application scaling such as processor decomposition, parallelisation models and runtime libraries, and their associated effects on memory consumption. We demonstrate how the data storage model of OpenMPI implementations inherently prevents scaling due to memory requirements, and investigate the benefits of different solutions. Finally, we show how by analysing information gathered during application execution we can automatically generate models to predict application memory consumption, at different scale and runtime configurations. In addition we predict, using these models, how implementation changes could affect the memory consumption of an industry strength benchmark.

Full textAbstract:
Mobile applications provide services that can benefit various sectors of the society. It is imperative that the realization of mobile applications be well-planned and based on standards. The interplay of Extensible Markup Language (XML)-based technologies, software engineering principles, and "best practices" formalized as patterns provides such a systematic approach. This thesis formulates a rigorous classification of mobile application patterns into four categories: architecture, process, product, and usage. To express the patterns in a universal manner, an XML-based pattern notation, the Mobile Application Patterns Markup Language (MAPML), is introduced. Based on a requirements analysis and design description, the specification of MAPML is given. MAPML is equipped with a collection of tools that includes formal grammars for MAPML, and solutions for authoring, processing, and presenting MAPML documents on the Web. The thesis concludes with a discussion of the current state of work and directions for future improvement.

Piggin, Richard Stuart Hadley. "Application and development of fieldbus : executive summary." Thesis, University of Warwick, 1999. http://wrap.warwick.ac.uk/36357/.
Full textAbstract:
Confusion over fieldbus technology by manufacturers and customers alike is due to a number of factors. The goal of a single global fieldbus standard, the subsequent development of European standards, the recognition of a number of emerging de facto standards and the continued international standardisation of fieldbus technology is still perplexing potential fieldbus users. The initial low supply and demand for suitable devices and compatible controller interfaces, the high cost of control systems and inertia caused by resistance to change have all contributed to the slow adoption of fieldbus technology by industry. The variable quality of fieldbus documentation has not assisted the acceptance of this new technology. An overview of industrial control systems, fieldbus technology, present and future trends is given. The quantifiable benefits of fieldbus are identified in the assessment of fieldbus applications and guidance on the appropriate criteria for the evaluation and selection of fieldbus are presented. End users can use this and network planning to establish the viability, suitability and benefits of various control system architectures and configurations prior to implementation. The enhancements to a network configuration tool are shown to aid control system programming and the provision of comprehensive diagnostics. A guide to fieldbus documentation enables manufacturers to produce clear, consistent fieldbus documentation. The safety-related features for a machine safety fieldbus are also determined for an existing network technology. Demonstrators have been produced to show the novel use of fieldbus technology in different areas. Transitory connections are utilised to reduce complexity and increase functionality. A machine safety fieldbus is evaluated in the first installation of a fully networked control application. Interoperability of devices from many different manufacturers and the benefits of fieldbus are proven. Experience gained during the membership of the British Standards Institution AMT/7 Committee identified the impact of standards and legislation on fieldbus implementation and highlighted the flawed use of standards to promote fieldbus technology. The Committee prepared a Guide to the evaluation of fieldbus specifications, a forthcoming publication by the BSI. The Projects presented have increased and developed the appropriate use of fieldbus technology through novel application, technical enhancement, demonstration and knowledge dissemination.

The research is based on fieldwork in the Johannesburg East District where fifteen teachers from different schools participated. The teachers were from a variety of backgrounds in teaching the subject. Each of the teachers voluntarily completed an open-ended questionnaire that was based on their own interpretation of the setting of formal assessment tests or examinations. Document analysis was performed on the preliminary theory examinations that were set by the teachers using an adapted form of Krathwohl‟s two-dimensional taxonomy which was made specific for CAT. The teachers were requested to supply an example of a taxonomy which they themselves had used when analyzing the preliminary theory examination according to cognitive levels. The research findings were derived from the responses to the questionnaires that indicated the teachers‟ opinions about the setting of formal assessments as well as from formal test papers the teachers provided. The vast majority of the participant teachers used examinations set by others, either those purchased from publishers or publically accessible past papers downloaded from the internet with minimal change. It appears that the teachers did not use any taxonomy of cognitive levels even when they designed their own question papers. The cognitive level addressed was primarily memorisation and recall. The teachers were more concerned about the format and style of their examination papers than the cognitive levels the papers addressed. Additionally the overwhelming majority did not believe that training in assessment design would be of value to them (as experienced teachers), although some suggested that such training may be useful for beginning teachers. This suggests that further research on the teachers‟ experiences in using taxonomies when setting formal assessments, as well as potential in-service training interventions that address their knowledge of cognitive levels and appropriate assessments is needed.<br>Dissertation (MEd)--University of Pretoria, 2013.<br>gm2014<br>Science, Mathematics and Technology Education<br>unrestricted

Full textAbstract:
Mobile applications can be developed using a variety of different techniques and technologies. One of the most recent of these techniques is the Progressive Web Application (PWA), a cross-platform solution that is built exclusively using common web technologies. The technique has great potential to become a major competitor to native applications but is currently held back by a few rather significant limitations. This project was initiated because of a significant lack of academic research on the topic of PWA, and a perceived poor level of knowledge in the industry about the technique. The goal of the project was to determine if PWA deserved broader utilization or if the current low level of adoption was justified. During the project, two surveys were conducted. The first survey asked mobile application developers from companies in different countries about things such as their knowledge of, experience with, and opinions of PWA. The second survey asked similar questions but was instead answered by lecturers in higher education in Sweden only. The results of this project show that the average level of knowledge of PWAis very low and that developers’ opinions of the technique are quite negative. The limitations of PWA were found to be few but crippling to its potential to achieve widespread adoption.

In one study students used GIL, a simple application framework, for their programming assignments in a second-semester programming course. Improvements in student performance were realized. In the other study, students submitted detailed logs of how time was spent on projects, along with their programs. Software metrics were computed on the students' source code. Correlations between student performance and the log data and software metric data were sought. No significant indicators of performance were found, even with factors that are commonly expected to indicate performance. However, results from previous research concerning variations in individual programmer performance and relationships between software metrics were obtained.<br>Master of Science

Full textAbstract:
The thesis describes the development of a computer-aided design and computer-aided draughting package of industrial gearboxes for transmitting power between shafts having parallel major axes. The package mainly consists of the following functions: (a) Determination of gear tooth numbers from the properties of continued and conjugate fractions (b) Generation of gear teeth by a rack-type cutter (c) Calculation of gear tooth profile and production of gear tooth grid for finite element stress analysis (d) Detailed strength analysis and design of a spur or helical, external or internal, standard or modified, single- or double- reduction gear set based on the ISO gear standards (e) Shaft design and analysis (f) Bearing selection and analysis (g) Production of the working drawings of the main gearbox components. This package works on the IBM PC and its compatible machines, operates in an interactive mode, combines the experience of the designer with the power of the computer, and produces substantial savings in time and cost over conventional design methods. Design examples illustrating this package are given. In addition, the maximum tooth root bending stresses have been studied by using finite element techniques and the results have been compared with those using the ISO gear standards.

Sun, Pi-Hwa. "Distributed empirical modelling and its application to software system development." Thesis, University of Warwick, 1999. http://wrap.warwick.ac.uk/78784/.
Full textAbstract:
Empirical Modelling (EM) is a new appro~h for software system development (SSO) that is particularly suitable for ill-defined, open systems. By regarding a software system as a computer model, EM aims to acquire and construct the knowledge associated with the intended system by situated modelling in which the modeller interacts with the computer model through continuous observations and experiments in an open-ended manner. In this way, a software system can be constructed that takes account of its context and is adaptable to the rapidly changing environment in which the system is developed and used. This thesis develops principles and tools for distributed Empirical Modelling (OEM). It proposes a framework for OEM by drawing on two crucial theories in social science: distributed cognition and ethnomethodology. This framework integrates cognitive and social processes, allowing multiple modellers to work collaboratively to explore, expand, experience and communicate their knowledge through interaction with their networked computer models. The concept of pretend play is proposed, whereby modellers as internal observers can interact with each other by acting in the role of agents within the intended system in order to shape the agency of such agents. The author has developed a tool called dtkeden to support the proposed OEM framework. Technical issues arising from the implementation dtkeden and case-studies in its use are discussed. The popular star-type logical configuration network and the client/server· communication technique are exploited to construct the network environment of this tool. A protocol has been devised and embedded into their communication mechanism to achieve synchronisation of computer models. Four interaction modes have been implemented into dtkeden to provide modellers with different forms of interpersonal interaction. In addition, using a virtual agent concept that was initially devised to allow definitions of different contexts to co-exist in a computer model, a definitive script can be interpreted as a generic observable that can serve as a reusable definitive pattern. Like experience in everyday life, this definitive pattern can be reused by particularising and adapting it to a specific context. A comparison between generic observables and abstract data types for reuse is given. The application of the framework for OEM to requirements engineering is proposed. The requirements engineering process (REP) - currently poorly understood - is reviewed. To integrate requirements engineering with SSD, this thesis suggests reengineering the REP by taking the context into account. On the basis of OEM, a framework (called SPORE) for the REP is established to guide the process of cultivating requirements in a situated manner. Examples of the use of this framework are presented, and comparisons with other approaches to RE are made.

Full textAbstract:
The harmony search algorithm was developed in 2001 as a heuristic optimisation algorithm for use in diverse optimisation problems. After its introduction it was extensively used in multiple engineering disciplines with great success. In order to demonstrate the value of harmony search in computer vision applications I developed four novel algorithms based on harmony search that efficiently solves three problems that are commonly found in computer vision, namely visual tracking, visual correspondence matching and binary image restoration. Computer vision is a large discipline that includes solving many different kinds of optimisation problems. Many of these optimisation problems are discontinuous with derivative information difficult or impossible to come by. The most common solution is to use population based statistical optimisation algorithms like the particle filter, genetic algorithms, PSO, etc. but harmony search has never been investigated as a possible alternative. This is surprising since harmony search has been shown to be superior to these methods in several other engineering disciplines.
I therefore aim to show that harmony search deserves to be included in the computer vision researcher's toolbox of optimisation algorithms through the introduction of four novel algorithms based on harmony search that solve three diverse problems in computer vision. First the harmony filter (HF) is introduced as a visual tracking algorithm that is shown to be superior to the particle filter and the unscented Kalman filter (UKF) in both speed and accuracy for robust tracking in challenging situations. The directed correspondence search (DCS) algorithm is then introduced as a solution to the visual correspondence problem. Finally, two algorithms, counterpoint harmony search (CHS) and largest error first harmony search (LEFHS), are introduced for the blind deconvolution of binary images.
Comparative results from these algorithms are very promising. The harmony filter was compared with the particle filter and the UKF both of which have been extensively used in visual tracking. In challenging situations consisting of rapid and erratic target movement, extended periods of total and partial occlusion and changing light conditions, the HF proved to be more accurate and faster on average than both the particle filter and the UKF. Under various conditions I show that the HF is at least 2 times faster than a UKF implementation and 4 times faster than a particle filter implementation (using 300 particles).
While there are fewer algorithms specialising in the blind deconvolution of binary images, CHS and LEFHS were compared with a current state-of-the-art method and proved to be more robust to noise and more accurate. LEFHS is the only algorithm currently available that can recover a 24 x 12 binary image using blind deconvolution to 100% accuracy without putting constraints on the point spread function (blurring kernel).
During the development of these algorithms several valuable insights into the inner workings of harmony search were discovered. In each application harmony search had to be adapted in a different way and with each new adaptation a deeper understanding of the advantages of harmony search is revealed. Knowing which components may be modified without degrading performance is key to adapting harmony search for use in diverse problems and allows one to use harmony search in situations it was not originally designed for without losing its superior performance. These insights and the adaptation strategies that they lead to are the main contribution of this thesis.

This thesis implements Milton Babbitt's time-point system for music composition via the creation of a computer software application for the Macintosh computer. This system asks the composer to enter musical information, which is used to calculate pitch, duration, articulation, texture, octave, and silence, for the time-point composition. The application generates a file of musical information that is compatible with a performance application; the performance application will execute the composition communicating with MIDI-compatible musical instruments.The purpose of this project was to create a compositional tool that would implement the time-point system by reducing hours of hand calculation and tedium, and would provide an accessible and efficient approach to time-point composition. It is intended that this application be used to assist both the serious composer as well as the student of music composition.<br>School of Music

The use of computer application software could be increased. The goal of this research was to uncover a design for a module which instructs the potential user how to use software. This type of module, called an instructional module, would, when incorporated on software such as decision support tools, increase the willingness of novices to use the software more frequently. Four instructional modules designs, which were the result of combining two states of two variables of instructional module design, were examined. The four designs are (1) an automated programmed learning module; (2) an automated help facility; (3) a manual programmed learning module and; (4) a manual help facility. A financial decision support tool was developed, and each of the four instructional modules designs was placed separately on the decision support tool. This created, in effect, four different tools. Subjects in the experiment were business school students with no formal experience using a decision support tool. Each subject was exposed to two of the four instructional module designs during a training session which lasted one hour. One month after the training session, the subjects were reassembled for a second session. During this session, the subjects selected one of the two tools, with its instructional module, which they had been exposed to previously. The subjects were to use the selected tool to solve problems which would likely require them to access the instructional module. In addition to these behavioral selection data, attitudinal data concerning the instructional module designs were also collected throughout both sessions of the experiment. Based on their selection and their attitudinal responses, the subjects indicated that the tool with the automated programmed learning module was the module of choice. The research methodology successfully provided input for instructional module design for computer application software such as decision support tools.

Pastures established using buffelgrass (Cenchrus ciliaris L.) have shown heterogeneous responses in terms of forage production and permanence. A good alternative for determining establishment sites and predict trends in buffelgrass conditions is the use of simulation models. The objectives of this research were to determine the factors that regulate successfulness in buffelgrass pastures and to develop a model to determine suitability in areas managed for buffelgrass pastures, based on environmental, ecological, and management variables. Above ground biomass production was considered to determine suitability in sites with buffelgrass. Eight ranches with different geographic locations, environmental situations, and management conditions were sampled as preliminary study sites to measure and model plant production. The resulting model was used to estimate plant production in the 37 sampling sites of the study areas. Results of the study indicate that basal area is a good modeling parameter to estimate production in buffelgrass plants. I also found that plant production in buffelgrass is negatively affected by population density. I concluded that there exist a positive correlation between pasture management and buffelgrass plant production. Correlation analyses demonstrate that there exist significant correlations between Pasture Condition Index (PCI) and mean annual temperatures, aspect, pasture age, nitrogen and sodium content. However, after performing stepwise regressions, only three variables were significant: pasture age (PA), nitrogen content (N2), and mean annual temperature (MAT); the last two, produce a negative response on PCI.

Full textAbstract:
The possibility of incorporating Artificial Intelligence (A.I) techniques into Visual Interactive Discrete Event Simulation was examined. After a study the current state of the art, work was undertaken to investigate the usefulness of PROLOG as a simulation language. This led to the development of a working Simulation Engine, allowing simulations to be developed quickly. The way PROLOG facilitated development of the engine indicated a possible usefulness as a medium for controlling external simulations. Tests on the feasibility of this were made resulting in the development of an assembler link which allows PROLOG to remotely communicate with and control procedural language programs resident on a separate microcomputer. Experiments using this link were then made to test the application of A.I. techniques to current visual simulations. Studies were carried out on the controlling of the simulation, the monitoring and learning from a simulation, the use of simulation as a window to expert system performance, and on the manipulation of the simulation. This study represents a practical attempt to understand and develop the possible uses of A.I. techniques within visual interactive simulation. The thesis concludes with a discussion of the advantages attainable through such a merger of techniques, followed by areas in which the research may be expanded.

The software engineering tools and techniques available for use in traditional information systems industries are far more advanced than in the manufacturing and production industries. Consequently there is a paucity of ladder logic programming support tools. These tools can be used to improve the way in which ladder logic programs are written, to increase the quality and robustness of the code produced and minimise the risk of software related downtime. To establish current practice and to ascertain the needs of industry a literature review and a series of interviews with industrial automation professionals were conducted. Two opportunities for radical improvement were identified; a tool to measure software metrics for code written in ladder logic and a tool to detect cloned code within a ladder program. Software metrics quantify various aspects of code and can be used to assess code quality, measure programmer productivity, identify weak code and develop accurate costing models with respect to code. They are quicker, easier and cheaper than alternative code reviewing strategies such as peer review and allow organisations to make evidence based decisions with respect to code. Code clones occur because reuse of copied and pasted code increases programmer productivity in the short term, but make programs artificially large and can spread bugs. Cloned code can be removed with no loss of functionality, dramatically reducing the the size of a program. To implement these tools, a compiler front end for ladder logic was first constructed. This included a lexer with 24 lexical modes, 71 macro definitions and 663 token definitions as well as a 729 grammar rule parser. The software metrics tool and clone detection tool perform analyses on an abstract sytax tree, the output from the compiler. The tools have been designed to be as user friendly as possible. Metrics results are compiled in XML reports that can be imported into spreadsheet applications, and the clone detector generates easily navigable HTML reports for each clone as well as an index file of all clones that contains hyperlinks to all clone reports. Both tools were demonstrated by analysing real factory code from a Jaguar Land Rover body in white line. The metrics tool analysed over 1.5 million lines of ladder logic code contained within 23 files and 8466 routines. The results identified those routines that are abnormally complex in addition to routines that are excessively large. These routines are a likely source of problems in future and action to improve them immediately is recommended. The clone detector analysed 59K lines from a manufacturing cell. The results of this analysis proved that the code could be reduced in volume by 43.9% and found previously undetected bugs. By removing clones for all factory code, the code would be reduced in size by so much that it could run on as much as 25% fewer PLCs, yielding a significant saving on hardware costs alone. De-cloned code is also easier to make modifications to, so this process goes some way towards future-proofing the code.

Full textAbstract:
Our aim is to establish the partial metric spaces within the context of Theoretical Computer Science. We present a thesis in which the big "idea" is to develop a more (classically) analytic approach to problems in Computer Science. The partial metric spaces are the means by which we discuss our ideas. We build directly on the initial work of Matthews and Wadge in this area. Wadge introduced the notion of healthy programs corresponding to complete elements in a semantic domain, and of size being the extent to which a point is complete. To extend these concepts to a wider context, Matthews placed this work in a generalised metric framework. The resulting partial metric axioms are the starting point for our own research. In an original presentation, we show that Ta-metrics are either quasi-metrics, if we discard symmetry, or partial metrics, if we allow non-zero self-distances. These self-distances are how we capture Wadge's notion of size (or weight) in an abstract setting, and Edalat's computational models of metric spaces are examples of partial metric spaces. Our contributions to the theory of partial metric spaces include abstracting their essential topological characteristics to develop the hierarchical spaces, investigating their To-topological properties, and developing metric notions such as completions. We identify a quantitative domain to be a continuous domain with a To-metric inducing the Scott topology, and introduce the weighted spaces as a special class of partial metric spaces derived from an auxiliary weight function. Developing a new area of application, we model deterministic Petri nets as dynamical systems, which we analyse to prove liveness properties of the nets. Generalising to the framework of weighted spaces, we can develop model-independent analytic techniques. To develop a framework in which we can perform the more difficult analysis required for non-deterministic Petri nets, we identify the measure-theoretic aspects of partial metric spaces as fundamental, and use valuations as the link between weight functions and information measures. We are led to develop a notion of local sobriety, which itself appears to be of interest.

Full textAbstract:
Plant phenotyping investigates how a plant’s genome, interacting with
the environment, affects the phenome (i.e. the observable traits of a plant).
Quantitative assessment of phenotypes is central to our quest towards
efficient and sustainable agriculture. Image-based approaches to plant
phenotyping are gaining momentum and, on par with growing scientific
and commercial interest, exciting computer vision problems arise. Currently
available solutions for image-based plant phenotyping are either
destructive and low-throughput or high-throughput and costly. We propose
an affordable solution based on a distributed sensing and analysis
framework. Time-lapse sequences of the scene are acquired by affordable
sensors (as such, they will have limited computational power and
knowledge access). The images are transmitted to the cloud, where high
computational resources permit the extraction of fine-grained phenotypic
information. For the automated analysis of such images, we develop a
multi-channel active contour segmentation with probabilistic priors on
plant appearance. To validate our approach we collect two image datasets
of growing Arabidopsis plants, portions of which are manually annotated
and publicly released. However, the transmission of large volumes of
image data necessitates compression to meet bandwidth constraints. After
demonstrating that lossy image compression does affect vision-based measurement
of plant traits and can jeopardize phenotypic analyses, we investigate
application-aware compression strategies on resource-constrained
devices to reduce transmission and storage cost of the acquired images
without compromising analysis accuracy. The possibility of sharing information
between sensor and receiver is exploited: the receiver feeds
back to the sensor information to optimize image compression. We inject
application knowledge at different levels of the lossy encoding process.
The sensor estimates regions of interest within an image and applies different
levels of compression to foreground (plants) and background. We
also save bits in color representation, using an orthogonal transform with
class separation capabilities obtained with supervised learning. Finally,
we investigate application-aware distortion metrics for pixel-level classification
accuracy, and their implementation in the rate control algorithm of
the High Efficiency Video Coding (HEVC) standard. We hope with such
an affordable solution to increase adoption of image-based approaches
to plant phenotyping by small labs and breeders, and also in developing
countries, in pursuance of the democratization of science and technology.

Full textAbstract:
Brain-computer interfaces (BCIs) are real-time communication systems which bridge the gap between human and machine, extracting useful neural signals from the brain and converting them into commands which allow the user to interact with computers or devices using their thoughts. BCIs have a wide range of applications, including gaming, research and entertainment. And they can also be used as part of an assistive device for disabled users. This PhD thesis focuses on two BCI types: the steady-state visually evoked potential (SSVEP) BCI, which is operated using gaze control, and the motor imagery-based BCI, which responds to imagined limb movements. Contained within are novel methods designed to improve each BCI type with respect to performance and user experience. New normalisation methods are found to improve SSVEP-BCI performance. A new three-dimensional SSVEP-BCI game is created, along with the Predicted Optimal Colour (POC) SSVEP-BCI, which automatically selects the optimal stimulus colours for a user in order to exploit differences in the way the brain responds to different coloured stimuli. And a feasibility study is conducted where we implement a new method for training users to operate a motor imagery-based BCI, and investigate predictors of BCI performance.

Full textAbstract:
The creative phases of design are based upon the human ability to conceptualise or abstract ideas from physical observations of the real world. That ability comes from experience, based on experiment: discerning patterns of behaviour in particular sets of observations. In this work it is shown that the process of identification, experiment and abstraction may be modelled accurately on a computer by definitive, or agent-oriented, programming, so forming a powerful aid to conceptual design. A new computer modelling language, called EdenLisp, has been developed by the author around Definitive Notations and interfaced to a commercial Computer Aided Design package. It provides a tool whereby computer models of systems can be originated that have state and on which state change can be made, not only by the designer but also by other autonomous agents of change Experiments with the language are described that show that scripts of definitions can have characteristics that permit the design to proceed as if there were an engineering prototype of the physical system being designed. The explicit representation of state at the lowest levels permits experimentation, observation of properties and addition of further observations. The interactive construction of EdenLisp is analogous to the conceptual design process It is used to illustrate and test design meta-theories for modelling conceptual design. It is shown to have potential for concurrent or multi-agent design, and is also an excellent vehicle for design education.

Traditional expert systems technology is limited, being hard to maintain and extend to new problems. In this thesis, I propose a logical formalization for the domain of computer hardware which will enable the use of theorem proving techniques for the task of computer hardware configuration. This domain was the subject of one of the earliest knowledge based systems, XCON. Whilst XCON is cited as a successful system, it has nevertheless also been criticized for its maintenance problems. This is an important issue, as the turnover of computer hardware components is particularly changeable, the market being subject to intense competition and rapidly changing technology. My approach enables the task of configuring a computer configuration <i>c</i> from a specification <i>spec(c)</i> to be performed by synthesizing <i>c</i> as a by-product of proving the theorem exists <i>c.spec(c)</i> when <i>c</i> becomes instantiated in the course of the proof. A clean separation of the object-level, heuristic and control knowledge enbales us to guide search and aids maintenance. As well as ensuring legal configurations, by virtue of the soundness of the underlying logical theory, I have also been able to take design issues into consideration by using heuristic and control knowledge.

Existing home care technology tends to be pre-programmed systems limited to one or two interaction modalities. This can make them inaccessible to people with sensory impairments and unable to cope with a dynamic and heterogeneous environment such as the home. This thesis presents research that considers how home care technology can be improved through employing multiple visual, aural, tactile and even olfactory interaction methods. A wide range of modalities were tested to gather a better insight into their properties and merits. That information was used to design and construct Dyna-Cue, a prototype multimodal reminder system. Dyna-Cue was designed to use multiple modalities and to switch between them in real time to maintain higher levels of effectiveness and acceptability. The Dyna-Cue prototype was evaluated against other models of reminder delivery and was shown to be an effective and appropriate tool that can help people to manage their time and activities.

Full textAbstract:
While computer networks have been of low capacity or poor reliability, their use for real-time communications for human interaction was considered infeasible on any large scale, since audio and video data consumed vast amounts of memory and processing capacity. However, recent and forthcoming enhancements to network quality, along with advanced compression algorithms, falling costs of memory and fast processors, have allowed such applications to develop, as well as protocols to support them. On top of this, global interconnectivity of local networks has improved, giving scope to expand human communications applications to wide areas, and with many participants. Such group communication applications have various networking Quality of Service (QoS) demands, such as lower bandwidth but high reliability. The mahor challenge in multimedia group communications is therefore about developing network services to support group communications with varying QoS, in order to allow groups of people, potentially very widely distributed around the world, to interact through computers of varying abilities, using combinations of media such as video, audio, and shared editing of documents. The Media Channel (MC) model is an attempt to unify the control and management of applications of different media types. It provides common group management facilities for all types of application, and allows participation in an application to be expressed simply as contribution (using a source) and/or observation (using a sink). This further allows a multimedia group application to be built up from several ‘unimedia’ group applications (the ‘channels’) through the use of a user agent which manages and simplifies a user’s participation in several applications. Participation in multimedia group applications (or ‘sessions’) can then be configured automatically for several users by describing the channels of the session to each involved user agent. The description itself can be supplied through a channel, with the agents acting as sinks. The user can control participation in all the channels of the session by (de)activating the agent’s session sink, and while joined, session administrators can inform all session participants of new channels to which they are invited. The MC model's main shortfall is its use of a central manager — an architecture which does not scale well to many participants, and which may lead to uneven management for widely distributed participants, particularly as group populations migrate. This thesis considers the issues of multimedia group communication, and attempts to realise the MC model. Some earlier definitions of the MC model are refined in the present thesis, and alternative architectures are designed, implemented and evaluated. These new architectures allow the management components of a media channel to be placed near to the participants, and then to migrate as participants leave the components’ areas, and as new ones join in others. At the same time, management information to evaluate policies is compressed and distributed among components. The model is also extended to allow sources to describe their data arbitrarily, enabling sinks to accept or reject them individually depending on availability of local resources.

Full textAbstract:
Mobile devices when provisioned with intuitive mobile healthcare (mHealth) applications provide a powerful platform that has been recognised to have made a significant impact on healthcare delivery. The popularity of mHealth applications is rapidly expanding amongst consumers and there is a continuous demand to improve the effectiveness of mHealth applications. Personalisation has already been acknowledged by the healthcare industry as a mechanism to improve healthcare delivery, recognising that each consumer is unique. Yet, a typical mHealth application is designed to cater for the needs of large target demographics and are frequently developed without the necessary knowledge and expertise of healthcare providers. As a result, they often fail to meet the consumer’s specific healthcare requirements. Since healthcare professionals understand the specific healthcare requirements of a consumer, they are best suited for developing personalised mobile healthcare applications. However, they do not possess the familiarity, skills and knowledge to address the challenges associated with mobile application development. Therefore, this research addresses the need for a new approach to personalised mHealth application development in the form of an extensible ontology-driven framework that enables healthcare professionals to create personalised mHealth applications for healthcare consumers. This research explored personalisation & the challenges of personalised mobile application development, existing approaches and related works. Followed by a detailed investigation into the various health-related functions available in mHealth applications designed for healthcare consumers, that led to the creation of the mHealth Application Function Taxonomy. The next phase presents the theoretical design and development considerations of the Personalised Mobile Application Development (PMAD) ontology. The PMAD ontology encapsulates key knowledge associated with the development of personalised mHealth applications, that can be operationalised to compensate for the missing domain expertise during the personalised mHealth application development process. The final and contribution of this research describes and defines the approach and components of the Personalised Mobile Application Development ontology-driven framework that addresses the limitations of existing end-user programming solutions and enables healthcare professionals to create personalised mHealth applications for healthcare consumers.

Full textAbstract:
User development of applications provides end users with an alternative to the traditional process of systems development by allowing them to solve job related problems by developing their own software applications. User developed applications (UDAs) support decision making and organisational processes in the majority of organisations, and the ability to develop small applications forms part of the job requirements for many positions. Despite its pervasiveness, there are many risks associated with user development of applications. These risks result primarily from decreases in application quality that arise when end users have had little training and do not follow system development methodologies.
The primary aim of the research described in this thesis is to gain a better understanding of UDA success. In particular, the thesis considers the role of system quality in UDA success and the ability of end user developers to judge whether the applications they develop will have a positive impact on their performance of tasks. The research also investigates factors that might impact upon this ability.
The research objectives were addressed through two empirical studies. Two possible models of UDA success provided the starting point for Study 1. The first model is DeLone and McLean's (1992) model of IS success, and the second model is a version of this model that was modified to address concerns about the DeLone and McLean model and to reflect current research about UDA success. The models were tested using data from a field study involving business people participating in a business policy simulation, where they developed spreadsheet applications to assist in decision making. Structural equation modelling was used to test the models. Neither of the models was well supported by the data. However, the analysis provided strong support for relationships between perceived system quality and user satisfaction, information quality and user satisfaction, user satisfaction and intended use, and user satisfaction and individual impact. It is notable that the model paths that were supported in Study 1 were primarily those that reflect user perceptions rather than objective measures. This study highlighted that user perceptions of information systems success play a significant role in the UDA domain. The results did, however, suggest that there might be a direct relationship between system quality and individual impact.
Study 2 was a laboratory experiment and the participants were end users from a range of organisations. A revised research model was developed based on the findings of Study 1, and structural equation modelling was again used to test the model. The model paths that were supported suggest that for small to moderate applications, increases in spreadsheet development knowledge lead to increases in system quality and consequently the development of better quality spreadsheets. They also suggest that for these kinds of applications, end users have realistic perceptions of system quality and hence that user satisfaction may be an appropriate measure of UDA success. The results of Study 2 also provided insight into the role of user involvement in end user development, clarifying the process by which benefits are obtained. The study also provided insight into the importance of spreadsheet development knowledge for successful use (as well as development) of a spreadsheet application.
The results described in this thesis have practical implications for the management of user development of applications. They highlight the need either to increase end user levels of development knowledge via training so that end users can cope with applications of greater complexity, or to provide other forms of support for development. The role of organisational standards and guidelines is also be considered in the thesis and it is suggested that there is a particular need for guidelines on what kinds of applications are suitable for end user development.
