In today's highly competitive landscape, new product development strategies are imperatives for companies to create and sustain competitive advantages. The objective of this research is to develop an integrated approach to automate, or aid, the design problem solving process. An Integrated Design System (IDS) is proposed focusing on the parametric and detail design. In this system, generation and evaluation of new design problems occur quickly and easily by changing the inputs for the design model. The IDS provides an integrated platform to incorporate available application programs such as CAD and FEM tools into a single system. Four major frameworks, namely information handling, problem decomposition, design space characterization, and problem solving, are proposed and embedded in it to implement the product development process. The information handling includes five aspects. A naming protocol is devised to organize the historical design cases. A search algorithm is proposed to retrieve a design case. A system-generated report is used to distribute the design information. A constraint definition frame is presented to define the relationships between design parameters. Two schemas, information matrix and constraint tree, are developed to represent information in the IDS. A diagonal-centered decomposition scheme is developed utilizing a Genetic Algorithm to decompose a complex design problem. In addition to the conventional genetic operators, two novel genetic operators, unequal position crossover and insertion mutation, are proposed. To characterize the design space, two methods, Incremental Response Method (IRM) and Artificial Neural Network (ANN), are presented. The IRM is derived from response surface method, while the back-propagated ANN is coded to be self-evaluated. The presented problem solving algorithm constitutes the solving mechanism of the IDS. Based on the assessment of the design objectives, all design parameters are given a priority index to facilitate the parameter selection. An independent recursive method is introduced in this algorithm to handle the design constraints. The case studies are performed on two design problems: a hard disk drive actuator arm and a shaft. The results show that the system can automatically align parameter values towards the objective values in a reasonable manner, and thus verify the feasibility of the embedded frameworks.

Annotation:
This research focuses on the development and study of Information and Communication Technology (ICT) that support religious practices and the use of standpoint theory in ICT evaluation studies. Three phases makeup this work: formative studies to understand how megachurches, their members and leaders use ICT in ways tied to their Protestant Christian faith and the design of a technology probe, a photo sharing website named ChurchShare. The final and most significant phase is the evaluation of this probe in two churches.
I deployed ChurchShare in a Christian church comprised of U.S. born individuals and argue this initial deployment took place with â ideal users,â or those I intended to use the application and who represent the traditional targets of HCC (Human-Centered Computing) research. More than 200 photos were uploaded to ChurchShare and findings suggest that the technology probe was successfully integrated into the churchâ s worship services. Standpoint theory guided the second deployment study that was conducted with individuals who are marginalized in HCC researchâ "Kenyan immigrants. Participants rejected ChurchShare and zero pictures were uploaded to the website. I compare findings from both deployments and conclude that conducting ICT evaluation studies with marginalized users leads to more objective findings than conducting such studies with ideal users. I end with a discussion describing how standpoint theory can be incorporated into HCC, focusing on how this approach offers a practical way for researchers to uncover value differences between themselves and the people who interact with their work.

Annotation:
The scenario-based design process, particularly with an emphasis on claims, captures and shares design knowledge that has promise in teaching design. However, the best methods are not fully understood yet. This thesis examines the areas of scenario-based design, claims relationships, and learning through cases with the goal of learning what can be improved to better support these processes.
In investigating those areas, an information visualization tool is created for learning design through case studies. The tool combined claims from multiple visualization techniques to create an approach for supporting problem-based learning goals. In creating the tool, scenario-based design was used, with a particular emphasis on claims for driving the development and evaluation. All design rationale was captured in claims to create a tool that addressed the current problem issues identified. A recently developed claims relationship framework, used for the first time in development efforts, aided in structuring the design rationale. Using these relationships, the design was tracked from requirements analysis to problem claims to design claims and finally to claims that formed the basis of an evaluation.
This thesis presents a case study of using claims relationships to drive the development and evaluation of a tool for supporting problem-based learning through case studies of scenario-based design. In creating a novel tool for learning about cases, a unique example of claims-centric scenario based design emerges, presenting as open questions new directions for merging scenarios, claims, and cases in knowledge storage, access, and learning systems.Master of Science

Annotation:
The lack of real and speedy success in the implementation of Computer Aided Design (CAD) in small firms has been a cause for concern for the author for some years. Whilst much has been written about the implementation of Management Information Systems and about Advanced Manufacturing Technology in large firms, the literature on small firms is very sparse, and the implementer has nowhere to go for guidance. This research looks at the implementation of CAD in six small firms against the background of the current literature in associated areas. It focusses on the aspects of implementation most commonly featured in the implementation texts, developing some 32 Propositions on the basis of the six cases. A review of the propositions suggests a parallel between their sequence and what may be regarded as a "traditional" business plan, which addresses the questions:- where are we now? - where do we want to go?- how do we plan to get there?- what steps must we take?- how will we know when we get there? The link between the propositions and the structure is strong, and the consequence is clear. If the propositions indicate a structure, then a structure developed specifically to incorporate the propositions should result in a methodology for implementation. The framework for this methodology is developed, based upon five phases or stages:- strategy- company audit- design- action- review. The framework has been tested and amended, and the inputs to the phases have been identified. Sources for these inputs have also been specified where necessary. The framework provides a significant step forward in the understanding of Computer Aided Design implementation in small firms. In particular:- it is constructed using "hard" data- it provides guidance on a "best" way of implementing- it forms the basis of an implementation "toolkit"- it addresses the needs of the small firm, which can least afford specialist help and can least afford failure.

Annotation:
For both the CAVETM and the adaptable technology possessed by the University of New Orleans, crystal eye glasses are used to produce a stereoscopic view, and an ascension flock of birds tracking system is employed for tracking of the user's head position and position of a wand in 3D space. It is argued that with these immersive technologies along the use of gestures and hand movements should provide a more natural interface with the immersive virtual environment. This allows a more rapid and efficient set of actions to recognize geometry, interaction with a spatial environment, the ability to find errors, or navigate through an environment. The wand interface is used to provide an improved means of interaction. This study quantitatively measures the differences in interaction when compared with traditional human computer interfaces. This work uses competitive usability in four different Benchmarks: 1) navigation, 2) error detection/correction, 3) spatial awareness, and 4) a “shopping list†of error identifications. This work expands on [Butler & Satter's, 2005] work by conducting tests in the CAVETM system, rather than principally employing workbench technology. During testing, the testers are given some time to “play around†with the CAVETM environment for familiarity before undertaking a specific exercise. The testers are then instructed regarding tasks to be completed, and are asked to work quickly without sacrificing accuracy. The research team timed each task, counted errors, and recorded activity on evaluation sheets for each Benchmark test. At the completion of the testing scenarios involving Benchmarks 1, 2, 3, or 4, the subjects were given a survey document and asked to respond by checking boxes to communicate their subjective opinions.

Fung, Alex C. W. „Management of educational innovation : the case of computer aided administration“. Thesis, University College London (University of London), 1992. http://discovery.ucl.ac.uk/10019053/.
Annotation:
This thesis is concerned with the process of managing an educational innovation - computer-aided administration (CAA) for schools. From literature reviews in the areas of management of change and computer assisted school administration, together with findings from an observer case study in the United Kingdom, a model was generated for the CAA innovation process as a contribution to theory. The model was then put into practice as the framework for the CAA innovation process in a secondary school in Hong Kong. The innovation was successfully assimilated by the school in a period of about three years with the researcher acting as the change facilitator, and the model of the innovation process was subsequently refined. This refined "SIX-A" model it is hoped will be a contribution to practical change management. Before making conclusions, findings about the process of innovation as well as findings specific to CAA from the case school are compared and contrasted to data collected from three other schools' CAA innovations in Hong Kong.

Annotation:
The engineering design process may be seen as a series of interrelated operations that are driven by decisions: each operation is carried out as the consequence of an associated decision. Hence, an effective design process relies heavily upon effective decision-making. As a consequence, supporting decision-making may be a significant means for achieving design process improvements. This thesis concentrates on how to support selection-type decision-making in conceptual engineering design.

McDonnell, Janet Theresa. „Supporting engineering design using knowledge based systems technology with a case study in electricity distribution network design“. Thesis, Brunel University, 1994. http://bura.brunel.ac.uk/handle/2438/5443.
Annotation:
This thesis explores the architectural requirements of engineering design support systems based on knowledge based systems technology. The exploration is based on an understanding of the nature of designing as a professional activity and on the extent to which designers' competence can be modelled. Attention is focused on certain salient aspects of designers' competent behaviour. The theoretical study leads to the specification of requirements to be satisfied by a knowledge based system which will support designers in their professional setting and to the proposal of some knowledge based system components which will meet the requirements identified. The theoretical aspect of the thesis is complemented by a case study based on a designer of high voltage electricity distribution networks. The case study illustrates the theoretical component of the thesis and the methodological basis for the work. The practical realizability of the components of the knowledge based systems architecture proposed are demonstrated using the results of the analysis of the knowledge elicited in the case study without prejudicing the general applicability of the ideas. An object-oriented knowledge engineering software development environment is used to demonstrate how some components of the design situation represented can be implemented.

Khalid, Halimahtun Mohd. „Human factors of integrating speech and manual input devices : the case of computer aided design“. Thesis, University College London (University of London), 1990. http://discovery.ucl.ac.uk/1420894/.
Annotation:
The thesis investigates integrating the use of speech input and manual input devices in human-computer systems. The domain of computer aided design (CAD) is used as a case study. A methodology for empirical evaluation of CAD systems is presented. The methodology is based on a framework that describes the input/output processes presumed to underlie performance in design activities, using behaviour protocols and performance indices as data. For modelling system behaviour, a framework derived from the Blackboard architecture of design is described. The framework employs knowledge sources to represent different behaviour types recruited during CAD performance. Variability in user behaviour throughout the investigation is explained with reference to the model. The problems that expert CAD users experience in using manual input devices are first documented in an observational study conducted at their workplace. This demonstrates that the unitary use of manual input resulted in non-optimal behaviour. Possible solutions to these problems, using speech input for some command and data entry tasks, are explored in three experiments. In each experiment, a comparative analysis of alternative systems is made using data obtained from naive and novice users. In Experiment 1, the use of speech as a unitary solution to the problems of manual input was also found to result in non-optimal behaviour and performance. The solution explored in Experiment 2 was to allocate some commands and alphanumeric data to each input device, using the frequency of use principle. This approach, however, entailed the additional problem of remembering which device to use. Experiment 3 evaluated the separate allocation of commands to speech input and numeric plus graphical data to manual input. Additionally, performance aids and feedback facilities were provided to users. This clear-cut assignment of device to task characteristics and the use of such aids led to an enhancement in speech performance, in addition to improving behaviour. The findings from this research are used to develop guidelines for an integrated CAD system involving speech and manual input. The guidelines, which are intended for use by end users, CAD implementors and system designers, were validated in the workplace by the latter. Lastly, the thesis contextualises the research within an ergonomics framework, mapping the research development from problem specification to application and synthesis. Problems with the investigation are also discussed, and suggestions made as to how these might be resolved.

Annotation:
Carbohydrates are abundant in nature and have functions ranging from energy storage to acting as structural components. Analysis of carbohydrate structures is important and can be used for, for instance, clinical diagnosis of diseases as well as in bacterial studies. The complexity of glycans makes it difficult to determine their structures. NMR spectroscopy is an advanced method that can be used to examine carbohydrates at the atomic level, but full assignments of the signals require much work. Reliable automation of this process would be of great help. Herein studies of Escherichia coli O-antigen polysaccharides are presented, both a structure determination by NMR and also research on glycosyltransferases which assemble the polysaccharides. The computer program CASPER has been improved to assist in carbohydrate studies and in the long run make it possible to automatically determine structures based only on NMR data. Detailed computer studies of glycans can shed light on their interactions with proteins and help find inhibitors to prevent unwanted binding. The WaaG glycosyltransferase is important for the formation of E. coli lipopolysaccharides. Molecular docking analyses of structures confirmed to bind this enzyme have provided information on how inhibitors could be composed. Noroviruses cause gastroenteritis, such as the winter vomiting disease, after binding human histo-blood group antigens. In one of the projects, fragment-based docking, followed by molecular dynamics simulations and binding free energy calculations, was used to find competitive binders to the P domain of the capsid of the norovirus VA387. These novel structures have high affinity and are a very good starting point for developing drugs against noroviruses. The protein targets in these two projects are carbohydrate binding, but the techniques are general and can be applied to other research projects.At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 4: Submitted. Paper 5: Manuscript. Paper 6. Manuscript.

Rajab, Khairan. „Knowledge Guided Non-Uniform Rational B-Spline (NURBS) for Supporting Design Intent in Computer Aided Design (CAD) Modeling“. Scholar Commons, 2011. http://scholarcommons.usf.edu/etd/3302.
Annotation:
For many years, incompatible computer-aided design (CAD) packages that are based on Non-uniform Rational B-Spline (NURBS) technology carried out the exchange of models and data through either neutral file formats (IGES or STEP) or proprietary formats that have been accepted as quasi industry standards. Although it is the only available solution at the current time, the exchange process most often produces unsatisfactory results. Models that are impeccable in the original modeling system usually end up with gaps or intersections between surfaces on another incompatible system. Issues such as loss of information, change of data accuracy, inconsistent tolerance, and misinterpretation of the original design intent are a few examples of problems associated with migrating models between different CAD systems. While these issues and drawbacks are well known and cost the industry billions of dollars every year, a solution to eradicate problems from their sources has not been developed. Meanwhile, researchers along with the industries concerned with these issues have been trying to resolve such problems by finding means to repair the migrated models either manually or by using specialized software.
Designing in recent years is becoming more knowledge intensive and it is essential for NURBS to take its share of the ever increasing use of knowledge. NURBS are very powerful modeling tools and have become the de facto standard in modeling. If we stretch their strength and make them knowledge driven, benefits beyond current expectations can be achieved easily. This dissertation introduces knowledge guided NURBS with theoretical and practical foundations for supporting design intent capturing, retrieval, and exchange among dissimilar CAD systems. It shows that if NURBS entities are tagged with some knowledge, we can achieve seamless data exchange, increase robustness, and have more reliable computations, all of which are ultimate objectives many researchers in the field of CAD have been trying to accomplish for decades. Establishing relationships between a NURBS entity and its origin and destinations can aid with seamless CAD model migration. The type of the NURBS entity and the awareness of any irregularities can lead to more intelligent decisions on how to proceed with many computations to increase robustness and achieve a high level of reliability.
As a result, instead of having models that are hardly modifiable because of migrating raw numerical data in isolation, the knowledge driven migration process will produce models that are editable and preserve design intent. We have addressed the issues not only theoretically but also by developing a prototype system that can serve as a test bed. The developed system shows that a click of a button can regenerate a migrated model instead of repairing it, avoiding delay and corrective processes that only limit the effective use of such models.

The primary aim of this multidisciplinary project was to develop a new generation of breast implants. Disrupting the currently prevailing paradigm of silicone implants which permanently introduce a foreign body into mastectomy patients, highly porous implants developed as part of this PhD project are biodegradable by the body and augment the growth of natural tissue. Our technology platform leverages computer-assisted-design which allows us to manufacture fully patient-specific implants based on a personalised medicine approach. Multiple animal studies conducted in this project have shown that the polymeric implant slowly degrades within the body harmlessly while the body's own tissue forms concurrently.

Resumo: Bibliotecas digitais são avançados e complexos sistemas de informação que armazenam, agregam e gerenciam informações correlatas para que comunidades específicas possam ter acesso a objetos digitais de interesse. Grandes volumes de dados de diferentes tipos e formatos vêm sendo gerados. Muitos desses dados são organizados em objetos digitais que podem ser objetos complexos, ou seja, objetos compostos de outros objetos digitais. Como a especificação e a implementação de uma biblioteca digital são tarefas cruciais para um gerenciamento eficaz de documentos, ferramentas vêm sendo criadas para auxiliar na especificação e na implementação de bibliotecas digitais. Entretanto, poucas ferramentas existentes permitem a especificação de objetos complexos em bibliotecas digitais. Além disso, dificuldades são encontradas na especificação, na modelagem e no reuso desse tipo complexo de dado. O objetivo desta dissertação foi propor um metamodelo de bibliotecas digitais de objetos complexos para especificar instâncias de bibliotecas digitais que gerenciem objetos complexos. O novo metamodelo foi incluído na ferramenta 5SGraph, ferramenta gráfica baseada no formalismo 5S (Streams, Structures, Spaces, Scenarios e Societies) que permite a especificação formal de bibliotecas digitais. A validação do novo metamodelo foi realizada por estudos de caso, por uma avaliação com usuários potenciais da ferramenta 5SGraph e pela implementação de um protótipo de uma biblioteca digital de documentos legais. Com os resultados obtidos, comprovou-se que a ferramenta 5SGraph estendida pode ser usada para especificar bibliotecas digitais de objetos complexos. As principais contribuições deste trabalho são: a caracterização de documentos legais como objetos complexos; a especificação de um metamodelo para especificação de bibliotecas digitais de objetos complexos; a implementação de um metamodelo para uso na ferramenta 5SGraph com o objetivo de especificar e instanciar bibliotecas digitais contendo objetos complexos; uma apresentação de estudos de casos para especificar objetos complexos de bibliotecas digitais na ferramenta 5SGraph; a validação do uso do novo metamodelo na ferramenta 5SGraph por usuários potenciais; e a especificação e a implementação de um protótipo de biblioteca digital de objetos complexos do tipo documento legal
Abstract: Digital libraries are advanced and complex information systems that store, aggregate, and manage correlated information. These systems are used by specific communities to access digital objects of interest. Due to the creation of huge collections of heterogeneous data (in terms of type and format), some of these data are organized in digital complex objects, in the sense that they are composed by other digital objects. Since specification and implementation of digital libraries are decisive tasks to achieve an effective management of documents, specific software tools have been created to help and facilitate the specification and implementation of digital libraries. However, few existing tools used to model digital libraries allow the specification of complex objects. Besides, this kind of complex data make more difficult the tasks of specification, modeling, and reusing of complex objects. The objective of this dissertation was to propose a digital library metamodel in order to specify instances of digital libraries that manage complex objects. The new metamodel was included in the 5SGraph tool. 5SGraph is a software tool based on the 5S theory (Streams, Structures, Spaces, Scenarios, and Societies) and provides a visual environment for the formal specification of digital libraries. The new metamodel was validated through: case studies, an evaluation with potential users, and the implementation of a digital library prototype containing legal documents. According to the results, the extended 5SGraph tool can be used to specify digital libraries of complex objects. The main contributions of this work are: the characterization of legal documents as complex objects; the specification of a metamodel to be used in the specification of digital libraries of complex objects; the implementation of a metamodel in the 5SGraph tool, making the tool capable of specifying digital libraries of complex objects; the presentation of some case studies using the 5SGraph tool to specify complex objects of digital libraries; validation of the new metamodel in the 5SGraph with potential users; and the specification and implementation of a digital library prototype containing complex objects related to legal documents

This thesis explores roles of 2-oxoglutarate-dependent (2OG) oxygenases as interfaces that modulate steps in the flow of genetic information in cells in response to oxygen availability. Chapter 1 introduces mechanistic, biochemical and physiological aspects of major subfamilies of 2OG oxygenases, and their established regulatory roles in cells. In addition, structural and functional aspects of the ribosome and the translation process are discussed, with a focus on post-translational ribosome modifications. Chapter 2 investigates histone demethylases, which mediate chromatin-dependent regulation of gene expression and provides proof-of-concept for the rational, structure-guided design of small-molecules for selective inhibition of 2OG oxygenases with roles in cancer and inflammatory disease. Chapter 3 suggests regulatory roles for ten-eleven-translocation (TET)- catalysed DNA hydroxylation; calorimetric and thermal analyses reveal a duplex-stabilizing effect of the epigenetic 5-methylcytosine mark that is reversed upon conversion to 5- hydroxymethylcytosine (also termed the ‘sixth’ DNA base), raising the possibility that 2OG oxygenase catalysis might affect transcription via biophysical effects. Chapter 4 investigates fluoride release assays as a technology to enable medicinal chemistry studies on 2OG oxygenases with roles in fat mass regulation and obesity, cancer and inflammation; studies on the ALKBH5 enzyme show that it is a hypoxically upregulated 2OG oxygenase with a substrate preference distinct from previously characterized ALKBH enzymes. Chapter 5 identifies OGFOD1 as a 2OG-dependent ribosomal protein hydroxylase. OGFOD1 catalysis is conserved from yeast to humans. OGFOD1 catalyses formation of trans-3- hydroxy-L-proline in a highly conserved loop of ribosomal protein S23 proximal to the ribosomal decoding centre, possibly to modulate the interactions of eukaryotic ribosomes with tRNA, mRNA and translation factors in an oxygen-dependent manner. OGFOD1 is the functionally most well-conserved protein-modifying 2OG oxygenase; likewise, ribosomal protein S23 hydroxylation is the most well-conserved post-translational ribosome modification in eukaryotes. Some cell lines require OGFOD1 for proliferation, and scaffolds for OGFOD1- selective inhibitors are developed for use as potential antiproliferative agents and probes for cellular function. Chapter 6 shows the development of assays to investigate whether OGFOD1 catalysis affects ribosome assembly and function, including processivity, accuracy of initiation, elongation and termination, in yeast and mammalian cell lines. Chapter 7 concludes that ribosome hydroxylation might present an additional layer of regulatory complexity by which 2OG oxygenases could enable cells to respond to fluctuating oxygen levels.

Resumo: Soluções de Software de Gestão Empresarial (ERP - Enterprise Resource Planning) no Brasil são normalmente de código proprietário, caras de adquirir e implantar. No mercado brasileiro micro e pequenas empresas poderiam se beneficiar muito com a existência de soluções de ERP mais acessíveis. Uma possível solução seria o uso de programas de código livre para atender a essa demanda, tal como o projeto Apache Open For Business, um conjunto de aplicativos e um framework voltado para soluções de gestão empresarial. Neste estudo espera-se investigar a localização (processo de adaptação de um sistema para uma determinada cultura). Não apenas no que diz respeito a mera tradução dele, mas a aspectos legais, fiscais e contábeis, buscando aumentar sua usabilidade e viabilidade para empresários brasileiros
Abstract: In Brazil, Enterprise Resource Planning (ERP) software are usually proprietary, expensive to acquire and deploy. Micro and small businesses could benefit greatly from the existence of more affordable ERP solutions. One possible solution would be to use open source software to meet this demand. Of relevance in this scenario there is the project Apache Open For Business, a suite of applications and a framework aimed at business management solutions. The main purpose of this study is to investigate the localization (i.e. adapting computer software to different cultural contexts) of this software, not only regarding to mere translation, but also the legal, tax and accounting aspects, seeking to increase its usability and feasibility for Brazilian businessmen.

As depicted in Chapter I, 2-oxoglutarate- (2OG) dependent oxygenases are ubiquitous in living systems and display a wide range of cellular functions, spanning metabolism, transcription, and translation. Although functionally diverse, the 2OG oxygenases share a high degree of structural similarities between their catalytic sites. From a medicinal chemistry point of view, the combination of biological diversity and structural similarity presents a rather challenging task for the development of selective small molecules for functional studies in vivo. The non-selective metal chelator 8-hydroxyquinoline (8HQ) was used as a template for the generation of tool compound I for the KDM4 subfamily of histone demethylases via application of the Betti reaction. Structural analogue II was used as the corresponding negative control (Figure A). These compounds were characterised in vitro against a range of 2OG oxygenases and subsequently used for studies in cells. I displays selectivity for KDM4 and increases the level of the H3K9me3 histone mark in cells. It has an effect on the post-translational modification pattern of histone H3, but not other histones, and reduces the viability of lung cancer cells, but not normal lung cells, derived from the same patient. I also stabilises hypoxia-inducable factor HIF in cells via a mechanism which seems to be independent from prolyl hydroxylase inhibition. This work is described in Chapters II and III. The chemical biology research in epigenetics is complemented by qualitative analysis conducted in the social sciences at Said Business School. With a global view on how innovation occurs and may actively be fostered, Chapter IV focuses on the potential of epigenetics in drug discovery and how this process may actively be promoted within the framework of open innovation. Areas of focus include considerations of incremental and disruptive technology; how to claim, demarcate, and control the market; how knowledge brokering occurs; and insights about process, management, organisation, and culture of open innovation. In contrast to the open-skies approach adopted for the development of a tool compound in Chapters II and III, a focused-library approach was taken for the generation of a tool compound for the OGFOD1 ribosomal prolyl hydroxylase. The development of a suitable in vitro activity assay for OGFOD1 in Chapter V enabled the development of lead compound III in Chapter VI. III is selective for OGFOD1 against the structurally closely related prolyl hydroxylase PHD2.

Annotation:
This thesis presents the development and redesign of a commercial electrochemical quartz crystal microbalance with dissipation (E–QCM–D). This was used to study factors affecting the efficiency of the four electron reduction catalysed by the fuel cell enzyme bilirubin oxidase from Myrothecium verrucaria immobilised on thiol modified gold surfaces. Within this thesis, the E–QCM–D was used to show that application of a constant potential to bilirubin oxidase adsorbed to thiol-modified gold surfaces causes activity loss that can be attributed to a change in structural arrangement. Varying the load by potential cycling distorts the enzyme by inducing rapid mass loss and denaturation. Attaching the enzyme covalently reduces the mass loss caused by potential cycling but does not mitigate activity loss. Covalent attachment also changes the orientation of the surface bound enzyme as verified by the position of the catalytic wave (related to the overpotential for catalysis) and reactive labelling followed by mass spectrometry analysis. The E–QCM–D was used to show how electrostatic interactions affect enzyme conformation where high pH causes a reduction in both mass loading at the electrode and a reduction in activity. At pH lower than the enzyme isoelectric point, there is a build up of multilayers in a clustered adsorption. When enzyme adsorbs to hydrophobic surfaces there is a rapid denaturation which completely inactivates the enzyme. Changing the surface chemistry from carboxyl groups to hydroxyl and acetamido groups shows that catalysis is shifted to more negative potentials as a result of an enzyme misorientation. Further to this, increasing the chain length of the thiol modifier indicates that an increased distance between surface and enzyme reduces activity, enzyme loading and results in a conformational rearrangement that permits electron transfer over longer distances.

The purpose of this thesis is to carry out a computer aided design in three processes of the petroleum and petrochemical industries, namely (1) liquefied-natural-gas process, (2) ethyl tertiary butyl ether process, and (3) heptene process. The first case study is related to an LNG process. Due to the raising consciousness of the environmental protection, the government regulations for the pollution emission and the people’s request for the quality of living, the reduction of carbon dioxide emission and the using of liquefied natural gas has been a most important issue. The second case study is related to an ETBE process. The passage of 1991 Clean Air Act Amedment in the U.S. mandated the oxygen content in gasoline must be 2.7％. The oxygen content in the reformulated gasoline must be at least 2.0％ by the year 1995. Therefore, the using of oxygenated gasoline is a trend in most industrialized countries. The most common oxygenated gasoline are ether and alcohol. MTBE, which has been accepted worldwide as a means of meeting increasing octane requirement, is a good oxygenated compound ; however, it is now considered as a carcinogen. As a result, the use of other substitute as an octane booster is necessary. The third case study is related to a heptene process. The market for the i-heptene would be as a high octane blending agent for gasoline and in the production of plastcizers as well. In this thesis, the commercial simulation package ChemCAD was used to carry out the material balances and the sensitivity analysis for the three case studies.

It was conceived as a gift to the people of Australia and now stands on Acton Peninsula in Canberra, the nation's Capital. It is a visually complex manifestation of the design architects' (ARM) dialogue with the ambiguities of Australian history and national identity.

Completed three years earlier was probably the most debated work of architecture of the 1990s, the Guggenheim Museum (GMB) (1991-98) in Bilbao, Spain, by Frank O. Gehry and Associates (FOG&A). This satellite museum of the Guggenheim Foundation of New York was heralded as the quintessential example of a kind of architecture only possible because of advances in computer technologies. Both visually complex museums were conceived as flagship projects and consequently share many political, functional, and cultural expectations. Both were procured outside the usual adversarial designer/builder paradigm of western architecture and featured the innovative use of three-dimensional (CAD) software for design, documentation and analysis. The NMA project used a government instigated procurement method which was embraced by a group of design and construction companies who formed a joint venture known as the Acton Peninsula Alliance. This non-traditional or relationship-based procurement method required ARM to reassess their approach to generate and disseminate design data and their traditional relationship with other design and construction professionals. As part of this process, ARM were required to devolve some of their design authority to a project delivery team via a Design Integrity Panel and an Independent Quality Panel; both innovations integral to the Acton Peninsula Alliance. The NMA project reframed many of the enduring professional relationships of Australian architecture and in so doing extended the skill set and expectations of the architects and others to include a more substantial engagement with 3D CAD and a procurement system which was less subject to many of the common impediments inherent in the more traditional processes. Through a series of interviews with the architects and other stakeholders, a qualitative methodology was used to investigate the NMA as a case study which uses the GMB as an internationally recognised comparison. This thesis examines how these two projects have been successfully completed within time and budgetary constraints in an environment where flagship projects have had a history of highly publicised difficulties. It reveals that the successful realisation of the NMA was due to the relationships built or reframed as a result of this cooperative approach in conjunction with high levels of engagement with computer technologies. This is in contrast to the seamless flow of data and high levels of prefabrication integral to the success of the GMB.http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1255317

Annotation:
Software project development is increasingly becoming geographically distributed especially in today’s global business environment. In order to build quality software faster andat a lower cost, companies in industrialised countries are turning to globally distributed software development projects. Emerging countries such as India and Israel are known to have large pools of highly trained software engineers at relatively low cost. However, recent trends have shown that new locations are emerging as developmental sites. Examples of those locations in the Middle East include Oman, Dubai, Abu Dhabi and Qatar. The main attraction of those countries is that they are close to the Arab market. However, distributed development also entails a number of risks and problems, for instance in terms of communication and knowledge transfer between sites, resulting in project failures.
Being the project manager of a team that includes remote members has additional challenges compared to managing co-located team members. These projects face particular challenges that need careful managerial attention.This research aims to examine how globally distributed software development projects are managed in the Middle East. The main question to be answered was “How do companies in the Middle East successfully manage and organise software development in a globally distributed environment?”.
We outline the factors that were perceived as important by project managers. We also look at how culture affects the operation of virtual teams in a globally distributed software development environment in the Middle East taking religion into consideration. To understand how these factors influence the success of globally distributed software development projects in the Middle East, we conducted a qualitative case study research involving three different companies operating in Dubai, Oman, Abu Dhabi, India and Pakistan. We used semi-structured interviews as the primary sources of information as these allow highly personalised data.
This research outlines the following specific project management-related areas that need to be addressed to facilitate successful virtual team operation:
Cross-cultural collaboration
• Tools and technology used to facilitate GSD
• An infrastructure that facilitates communication between virtual teams
• Effective project managementComputing

Despite attempts by the South African government in partnership with private sector to equip schools with computers, research has shown that technology integration into teaching and learning is very low. Literature revealed that professional development or capacitation of teachers as the key element in enabling them to utilise technology and integrate it in their teaching practices. The main aim of this study was to design and develop Information Communication and Technology (ICT) instructional tools which were to be used to train teachers in primary schools on how to integrate ICT into teaching and learning. Design research and Instructional design theories were employed in guiding this study. The study used the ADDIE model of Instructional design as a guiding principle in the design and development of the tools.
The study is located in the positivist paradigm of exploring reality and the methodology employed in this study was quantitative in nature. The participants were 28 teachers from three primary schools. The sample was purposely selected since the schools were awarded computers after taking part in a water management project. The quantitative data to determine the participants‟ prior knowledge, effectiveness of the solution and the teachers‟ satisfaction with the designed solution were collected by means of two questionnaires administered in two phases: pre- and post- workshop.
The results of this study revealed that capacitation of teachers have to lay the foundation for ICT integration into teaching and learning. Giving computers to schools can lead to successful integration once the teachers feel competent to use them. Furthermore, it is crucial that other intervention strategies be explored, to empower teachers. It is recommended that this study be transferred to other similar situations.Curriculum and Instructional Studies

Annotation:
This thesis describes the evaluation of several computer supported martial arts learning environments. These learning environments were designed, developed and implemented for practitioners of Rough and Tumble (RAT), a South African martial art, originally as a result of an increasing number of RAT practitioners relocating to other countries and yet wishing to continue their learning and practise of RAT. This project revolves mainly around the effectiveness evaluation of whether RAT martial arts knowledge, skills and attitudes can be learned in computer supported learning environments. The research is situated within design research and has pragmatic goals to provide a computer supported learning environment for the learning of RAT. Furthermore the design research was conducted to derive design principles for future design and development efforts. A brief account of the literature is provided, covering three main learning paradigms, with a focus on behaviourism and constructivism, followed by a description of issues in the computer supported learning field, an explanation of various definitions of martial arts and how the term is delimited in this study, and an overview of various evaluation paradigms. This account revealed inadequacies of the theories and terminology described pertaining to this study, resulting in the combined use of various underlying theoretical approaches to guide this research. These approaches include the eclectic-mixed methods-pragmatic paradigm as the overarching framework, a social constructivist learning approach, cognitive flexibility theory, Bloom’s Taxonomy, the RAT approach to martial arts learning and teaching, and a mixed methods research design. Two main components were developed as solutions, which included the development of a computer martial arts resource, the RAT CD-ROM, and four online courses, the RAT Online courses. Data were collected using a number of research instruments, such as questionnaires, interviews, observations, records, expert reviews and learner artefacts in an attempt to understand the data from multiple viewpoints and develop a more reliable depiction of evaluation events. The data were analysed using mainly qualitative coding in software, expert rating diagrams, basic frequency statistics, and martial arts assessments of physical performances. These analyses revealed that although there is significant work involved in mixed methods research and there are issues such as participants not meeting task deadlines, technology failures, software usability issues, and small participant numbers, the research approach has contributed to the pragmatic goal of providing computer supported learning environments to RAT
practitioners, who otherwise would not have been able to participate in RAT. In addition a number of design principles for the creation of RAT computer supported learning environments were derived from this research, including the use of social constructivism, cognitive flexibility theory, Bloom’s Taxonomy, multiple contextual training, and using computers as learning and knowledge construction tools. These underlying theoretical principles translate to more practical procedural principles, such as amongst others, to design computer supported learning environments incorporating tools to enable knowledge construction and collaboration, provide learning designs that are complex and authentic, encourage multiple representations of learner knowledge, take on a mentor role as online course facilitator, and to build problem solving activities into the learning design.Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2011.

Software development is a process in continuous evolution. This characteristic implies also continuous changes in the functionality of the system under development. Some of these changes may cause problems when they are not properly and timely propagated to the project members. The aim of our research is to obtain a good understanding of problems caused by the lack of awareness of changes to features during a distributed software development project, to identify information and artifact repositories used by contributors, and then to draw the requirements of an awareness mechanism to tackle the awareness problem. In order to accomplish our research goals. we conducted a four month long case study at IBM Ottawa Software Lab. which we observed the collaboration patterns of a multi-site development project team.
Our findings helped us identify the most important communication media that support development. In particular, we observed that the 3-1% of communication was by phone and via face-to-face interactions. and email was mostly used to alert contributors about changes to features. We also found that changes were not properly and timely propagated due to different corporate cultures of the project teams. Finally, we found that a high volume of communication makes developers prone to overlook important information that can lead to the generation of errors during development., These findings led us to believe that miscommunication and non-timely communication of changes related to feature development caused the release of code that created failures in stable builds.
To address this problem. we developed the concept of a relationship to link developers to features. Using this concept, we have designed a feature-based Awareness Mechanism System to collect information, create relationships and deliver awareness information to the contributors involved in the implementation of a feature.

As a result of the support from the e-tutors, the curriculum was designed to place a strong emphasis on the design process as the core around which the teaching of the curriculum should revolve. However, it is still not clear how effective is the content knowledge which relates to the design process from the e-tutors. In acknowledgment from such a gap, this study aimed to determine the relationship between the e-tutors’ technological, pedagogical, content knowledge of teaching design process within Technology Education specialization. In order to achieve this purpose, two theories, namely Transactional distance and Connectivism were coined together with the Technological Pedagogical Content Knowledge (TPACK) framework to underpin the study. The philosophical worldview is pragmatism having employed mixed method. Participants in this study were 145 students who registered a year programme for two modules in the Bachelor of Education (B.Ed.) programme at a Higher Education institution were surveyed to collect the quantitative data. Data from the face-to-face semi-structured interviews were collected with five e-tutors from the research sites. Online observations data were collected from the e-tutor sites of the institution’s learning management system (LMS). The results suggest that e tutors still lack the technology knowledge in order to deliver the content aimed for the design process in an ODeL environment. Also, it was evidenced that the e-tutors have not acquired pedagogical strategies for driving the pedagogy for the design process in an ideal context of ODeL. It should also be borne in mind that findings for the content knowledge indicated that the e-tutors still lack the knowledge for exploiting content knowledge of the design process to suit an ODeL environment. These findings highlight a need for technology to support e tutors’ pedagogical strategies towards a meaningful understanding of the design process and its implications across ODeL contexts.

Ukutholakala kwe-Open Distance ne-e-Learning kuguqula izikhungo zemfundo ephakeme zabafundi ukuthi bathole imfundo nganoma yisiphi isikhathi noma kuphi. Abafundi bahlomule ngokufundiswa nganoma isiphi isikhathi noma kuphi kwesinye sezifundo zeTechnology Education ku-ODeL kubafundisi be-e. Njengomphumela wokwesekwa okwenziwa abafundisi be-e-tutors, ikharikhulamu yakhelwe ukugcizelela kakhulu inqubo yokwakhiwa njengongqikimba okumele kufundiswe ngayo ikharikhulamu. Kodwa-ke, akukacaci ukuthi lusebenza kangakanani ulwazi lokuqukethwe oluphathelene nenqubo yokwakha evela kubafundisi be-e. Ngokwazisa ngaleligebe elinje, lolu cwaningo luhlose ukucacisa ubudlelwano phakathi kwezobuchwepheshe be-e-tutors, ubuchwepheshe bokufundisa, ulwazi lokuqukethwe lwenqubo yokwakhiwa kokufundisa ngaphakathi kobuchwepheshe be-Technology Education. Ukufeza le njongo, imibono emibili, okungukuthi iTransactional distance neConnectivism yahlanganiswa kanye nohlaka lweTechnological Pedagogical Content Knowledge (TPACK) ukusekela ucwaningo. Umbono wezwe wefilosofi yi-pragmatism esebenzisa indlela exubile. Ababambe iqhaza kulolu cwaningo bekungabafundi abayi-145 ababhalise uhlelo lonyaka lwamamojula amabili kuhlelo lweBachelor of Education (B.Ed.) esikhungweni seMfundo ePhakeme bahlolisiswa ukuqoqa imininingwane yobungako. Imininingwane evela ezingxoxweni ezihlelekile ezenziwe ubuso nobuso zaqoqwa nama-e-tutors amahlanu avela kumasayithi ocwaningo. Idatha yokubuka eku-inthanethi yaqoqwa kusuka kumasayithi e-e-tutor ohlelo lokuphatha lokufunda (LMS). Imiphumela iphakamisa ukuthi abafundisi be-e basenalo ulwazi lobuchwepheshe ukuze bakwazi ukuletha okuqukethwe okuhloselwe inqubo yokwakhiwa endaweni ye-ODeL. Futhi, kufakazelwe ukuthi abafundisi be-e abakawatholi amasu okufundisa okushayela inqubo yokuqamba ngendlela efanelekile ye-ODeL. Kumele futhi kukhunjulwe ukuthi okutholakele kolwazi lokuqukethwe kukhombisile ukuthi ama-e-tutors asenalo ulwazi lokusebenzisa ulwazi lokuqukethwe kwenqubo yokwakhiwa ukuze ivumelane nemvelo ye-ODeL. Lokhu okutholakele kugqamisa isidingo sobuchwepheshe ukuxhasa amasu e-tutors 'pedagogical maqondana nokuqonda okunenjongo kwenqubo yokwakhiwa nemithelela yayo kuzo zonke izingqikithi ze-ODeL.

The design of a fixture that is based largely on previous experience is time-consuming work according to the traditional approach. The development of a computer-aided design system in this domain to assist designs, therefore, is very necessary. The Expert system is a popular technology of artificial intelligence and many fixture design expert systems have been developed. However, the development of a rule-based expert system is restricted because of some obstacles, specially in design domain. A technology superior to the expert system, called case-based reasoning (CBR), is employed in this study to improve these obstacles. Three systems are involved in this thesis. The first two systems employed the group technology (GT) to index input problem and cases. They are similar in system structure and reasoning except that one applied in dedicated fixture and the other one in modular fixture. A knowledge representation in CBR, called memory organization package (MOP), constitutes the third system that is also applied in modular fixture. An index system applied in modular fixture is also proposed in this thesis to be referred when characterizes the input problem and cases. It is believed that the result of this study can provide a new way to improve the capability of rule-based expert systems and establish a capable computer-aided design system.
