Full textAbstract:
Library users are constantly expecting new services, which puts tremendous pressure on academic libraries to re-organise their work patterns and devise better ways of service delivery in order to remain relevant. Although there are a lot of developments taking place in terms of information and communication technology (ICT), academic libraries in Sub- Saharan Africa are at different levels of ICT deployment both between different countries and within the same countries. The aim of this study is to determine the status of ICTs in Academic libraries in Central Uganda. The descriptive study employs a survey methodology gathering both quantitative and qualitative data. Data was collected from library staff responsible for the day-to-day management and administration of ICT at 17 of the 22 academic libraries in Central Uganda using survey questionnaires and interviews over a period of twelve months. Findings indicate that there is an improvement in the status of ICTs in academic libraries in Central Uganda although they are deployed at a minimum level. Funding, power fluctuations and low bandwidth still pose a major threat to ICT adoption in academic libraries in Central Uganda. This report informs government, libraries, LIS schools, LIS professional bodies and policy makers on the future course of action regarding ICT deployment and curricula. Notably, there is need for government to support infrastructural development; engage in public-private partnerships for infrastructural developments; exempt taxation of ICT equipment and supplement funding at universities. Libraries should dedicate more funds to purchase ICT equipment; automate all library functions; develop local capacity to manage ICT projects; promote awareness about ICT services and support initiatives from local and international library associations. LIS schools should conduct a curriculum review to reposition the LIS study program to the present and future needs of the job market; monitor and advice government on policy issues affecting higher education include the need to align ICTs to national development. LIS professional bodies need to champion the cause for the standardization of LIS study programs, promote networking and knowledge sharing; articulate national e-strategies and play advisory role to government, LIS schools and libraries.Mini Dissertation (MIT)--University of Pretoria, 2016.

Full textAbstract:
This study aimed to understand how Muni University Library can effectively use mobile technologies to deliver social media-based library services. Data was collected from 100 undergraduate students and 4 members of staff of the University Library on the use of mobile and social media technologies for provision of library services and resources using self-administered questionnaires and face-to-face interviews, respectively. Only 88 student questionnaires were returned while all 4 members of staff participated in the face-to-face interviews.
The results show that the majority (96.6 per cent) of the students own mobile devices and social media accounts that are used for both academic and personal purposes. There is convergence in responses among students and staff that mobile and social media technologies are crucial for provision of library services and resources in the 21st Century. They suggest that these technologies be used in the Muni University Library to access subject guides, MOPAC, mobile website, library map, and e-resources, and reference services. Also, the results show that the Muni University Library is already providing services to its users through mobile technologies and social media using WhatsApp, Facebook, and Kindle Fires e-readers.
However, this study identified challenges that hinder the use of mobile and social media technologies, including unreliable internet connectivity, lack of a member of staff of the library responsible for managing technologies, lack of adequate skills among users and library staff required to use social media technologies, and lack of an independent library social media strategy. Discussion of the results and recommendations are presented in this mini-dissertation.Mini Dissertation (MIT)--University of Pretoria, 2016.

Full textAbstract:
A diminuição das dimensões do transistor MOS tem sido a principal estratégia adotada para alcançar otimizações de desempenho na fabricação de circuitos integrados. Contudo, reduzir as dimensões dos transistores tem se tornado uma tarefa cada vez mais difícil de ser alcançada. Nesse contexto, vários esforços estão sendo feitos para encontrar dispositivos alternativos que permitam futuros avanços em relação à capacidade computacional. Entre as mais promissoras tecnologias emergentes estão os transistores de efeito de campo com múltiplos e independentes gates (MIGFETs). MIGFETs são dispositivos controlados por mais que um terminal de controle permitindo que funções Booleanas com mais de uma variável sejam implementadas por um único dispositivo. Redes de chaves construídas com dispositivos MIGFET tendem a ser mais compactas do que as redes de chaves tradicionais. No entanto existe um compromisso em relação a redução no número de chaves, devido à maior capacidade lógica, e um maior tamanho e pior desempenho do dispositivo. Neste trabalho, pretendemos explorar tal balanceamento no sentido de avaliar os impactos do uso de MIGFETs na construção de circuitos integrados digitais. Dessa forma, alguns critérios de avaliação são apresentados no sentido de analisar área e atraso de circuitos construídos a partir de dispositivos MIGFET, onde cada transistor é representado por um modelo RC. Em particular, tal avaliação de área e desempenho é aplicada no projeto de circuitos somadores binários específicos (metodologia full-custom). Além do mais, bibliotecas de células construídas a partir de dispositivos MIGFET são utilizadas na síntese automática de circuitos de referência através da metodologia standard-cell. Através dos experimentos, é possível ter-se uma ideia, mesmo que inicial e pessimista, do quanto o layout de um dado MIGFET pode ser maior do que um single-gate FinFET e ainda apresentar redução na área do circuito devido à compactação lógica.The scaling of MOS transistor has been the main manufacturing strategy for improving integrated circuit (IC) performance. However, as the device dimensions shrink, the scaling becomes harder to be achieved. In this context, much effort has been done in order to develop alternative devices that may allow further progress in computation capability. Among the promising emerging technologies is the multiple independent-gate field effect transistors (MIGFETs). MIGFETs are switch-based devices, which allow more logic capability in a single device. In general, switch networks built through MIGFET devices tend to be more compact than the traditional switch networks. However, there is a tradeoff between the number of logic switches merged and the area and performance of a given MIGFET. Thus, we aim to explore such a tradeoff in order to evaluate the MIGFET impacts in the building digital integrated circuits. To achieve this goal, in this work, we present an area and performance evaluation based on digital circuit built using MIGFET devices, where each MIGFET is represented through RC modelling. In particular, such an evaluation is applied on full-custom design of binary adder circuits and on standard-cell design flow targeting in a set of benchmark circuits. Through the experiments, it is possible have an insight, even superficial and pessimist, about how big can be the layout of a given MIGFET than the single-gate FinFET and still show a reduction in the final circuit area due to the logic compaction.

Full textAbstract:
A review of the innovation and diffusion literature indicates a considerable amount of research, where attention is given to a range of features which may support integration technologies adoption. However, some literature suggests that the findings derived from the study of large enterprises cannot be generalised and applied in SMEs due to the distinct characteristics of SMEs. Although the adoption of integration technologies is recognised as being different between large and small companies, the literature on its adoption by SMEs remains limited. Nevertheless, in existing work, there is a lack of studies emphasising the reasons why SMEs and large companies take the decision to adopt integration technologies, focusing specifically on the different factors. This thesis therefore identifies the significant differences in the way that SMEs and large companies approach integration technologies, based on the existing literature, theoretical diffusion theories, and resource-based theory. In doing so, the parameters that can be used to explain the adoption of integration technologies in SMEs and large firms are identified, as nature of organisations, company size, integration needs, adoption factors for SMEs and large organisations, and time. Additionally, adoption factors are found and classified into three categories: adoption factors explicit to SMEs, adoption factors explicit to large organisations, and common factors. Based on this, a conceptual model is introduced to explain the different factors that influence adoption between SMEs and large organisations. The empirical contexts of the research are one project on integration technologies adoption, and four case studies on a large firm and three SMEs, which are analysed using an interpretive and qualitative research approach. The evidence suggests that the empirical data complement the identified dimensions nature of organisations, integration needs, company size and time. The empirical data also confirm that the current integration technologies adoption factors reported in the literature can be classified into common factors, factors explicit to SMEs, and factors explicit to large firms, to support a more comprehensive view of this area. An additional factor perceived future prospect has been considered as an influence on adoption in large organisations. The findings of this research can be useful to guide analysts and researchers in determining critical aspects of the complex issues involved for integration technologies adoption, and lead to suggestions for further valid research.

This Master's Thesis compares technologies used in the architecture of Enterprise Resource Planning (ERP) Systems to evaluate the benefits and advantages of emerging technologies. The emerging technologies, Cloud Computing, Software as a Service (SaaS) and Multi-Tenancy, could significantly alter the current ERP space and become a primary part of ERP Systems of the future. A survey was sent to industry professionals to obtain feedback on their company's ERP Systems and to collect their comments on these new technologies. The survey results and related analysis show that Emerging Cloud ERP Systems outperform Traditional Legacy ERP Systems in all important characteristics - Accessibility, Business Cost, Implementation Time, Mobility, Scalability, Upgradability, and Usability. Cloud Systems were also found to have a shorter implementation time and a larger proportion of Cloud Systems were on the most recent version of software. Furthermore, industry professionals identified Cloud Computing, SaaS and Mobility as the emerging technologies of the coming decade. This thesis demonstrates that there are significant benefits for companies to use ERP Systems that use the emerging technologies and that the shift to Cloud ERP Systems has begun.

Le melanine sono biopigmenti di colore nero-marrone, ampliamente presenti in natura e comunemente conosciute per la colorazione dei capelli e degli occhi e per le funzioni biologiche che svolgono all’interno dell’organismo umano.
Nel corso degli anni, le melanine hanno suscitato sempre maggior interesse nella comunità scientifica a causa delle loro particolari proprietà fisiche e chimiche: le proprietà di foto-protezione e conduzione elettrica, le caratteristiche antiossidanti e di chelazione metallica la rendono un candidato molto interessante per possibili applicazioni in campo tecnologico. D’altra parte, le melanine sono costituite da un sistema chimico estremamente complesso e difficilmente trattabile, molti dei loro fondamentali principi di funzionamento sono ancora materia di studio.
Il progetto di tesi di seguito illustrato si è sviluppato all’interno di due sotto-progetti entrambi volti alla caratterizzazione del biopigmento. Il primo ha avuto come obbiettivo lo studio dei meccanismi di aggregazione delle sue unità costituenti sottoforma di thin film, per poi analizzarne le caratteristiche di conduzione elettrica in condizioni di vuoto.
Con il secondo progetto sono state studiate le proprietà di assorbimento della radiazione e le caratteristiche antiossidanti dell’eumelanina investigando il suo funzionamento come sostituto bio-sourced ai comuni UV-absorber all’interno dei polimeri utilizzati nell’industria del packaging.

Firms attempting to commercialize emerging technologies face unique challenges. Strategy making is one of the major challenges especially when the industry structure is embryonic. In this environment, it is important not only to remain flexible to accommodate the evolving market demands, but also to develop the infrastructure to respond to target markets quickly. This thesis presents a framework for developing a manufacturing strategy for emerging technologies and provides a case study for utilizing the model within fuel cell industry. The thesis develops a framework for manufacturing strategy, which includes four phases that lead to product introduction and capacity· expansion for the company to rapidly ramp up production if the product generates high demand. As further market information and customer input are obtained after product introduction, the different phases can be iterated to achieve low cost, high volume manufacturing for full commercialization. This framework was applied to understand International Fuel Cells business plan for residential/light commercial fuel cell commercialization, perform cost analysis on the product, identify core components, assess options for supplier development, determine operations requirements and examine options for capacity expansion. The business plan provided input into the project volumes of production. The production volumes were utilized to perform cost analysis. Cost analysis was used to identify potential technological breakthroughs that would render fuel cells competitive with existing technologies for power generation and transportation. Quality Function Deployment (QFD) was utilized to identify core subsystems and components. The different supply chain options and the applicable options for each of the core components were identified. These analyses provided insight into the components that needed investments for technology development. Operation requirements were estimated and capacity expansion options discussed. These options provided insight into the potential investments required. in the near term for residential fuel cell commercialization.

Over the last decade the aerospace industry has seen a shift in traditional architectures of an aircraft. The desire for aircraft to be lighter, more efficient, quieter, faster, and cheaper has driven trends across the industry. These trends look for ways to accomplish what many other industries such as automotive have done which is a complete transformation of the "normal." The shift has created an advanced architecture for aircraft and therefore requires a new view on certification. The traditional approach for certification is pretty straightforward since majority of aircraft have been the same over several years with minor changes in sub level aircraft systems. Aircraft manufacturers in combination with suppliers develop concepts for new or improved aircraft, requirements are outlined and implemented based on aviation authority regulations, and eventually the aircraft receives a certificate declaring the safety of the aircraft design and production. In fairness, the traditional standard approach to aircraft certification has worked. Aircraft are safer than ever and data shows a sharp decline in aviation accidents over the years. However, with changes in technology what use to be the "normal" architecture is changing significantly and the desire for the industry to be more agile both play a role in the need to view certification slightly different. The main objective of certification has been, is, and will always be safety. This thesis proposes a framework on how to approach certification of new technologies. Perhaps the two most important elements in the framework are the proposal of a threshold utilizing the technology infusion effort equation to gage the significance of a change in architecture and the proactive safety analysis utilizing a new kind of technique called STPA. The framework is developed based on an in-depth outline of the traditional certification process and a review of the historical development of safety regulations. Two parts of the proposed framework are then applied and analyzed based on the more electric aircraft concept.

Usage in information technology (IT) have improved efficiency and quality in many industries. Healthcare has not been one of them. Although some administrative IT systems, such as those for billing, scheduling, and inventory management, are already in place in the healthcare industry, little adoption of clinical IT, such as Electronic Medical Record Systems (EMR-S) and Clinical Decision Support tools, has occurred. India's healthcare information technology market is slow with technology adoption but there is little traction shown in last couple of years. This growth is expected to hit US $1.45 billion in 2018, more than three times the US $381.3 million reached in 2012. The increase in adoption of electronic health records, mHealth, telemedicine, and Web-based services has made electronic patient data expand, necessitating the implementation of robust IT systems in Indian healthcare institutions. Information technology (IT) has the potential to improve the quality, safety, and efficiency of health care. Diffusion of IT in health care is generally low (varying, however, with the application and setting) but surveys indicate that providers plan to increase their investments. Drivers of investment in IT include the promise of quality and efficiency gains. Barriers include the cost and complexity of IT implementation, which often necessitates significant work process and cultural changes. Given IT's potential, both the private and public sectors have engaged in numerous efforts to promote its use within and across health care settings. Delivering quality health care requires providers and patients to integrate complex information from many different sources. Thus, increasing the ability of physicians, nurses, clinical technicians, and others to readily access and use the right information about their patients should improve care. The purpose of this thesis is to assess the current state of healthcare in India and specifically look into the emerging technology trends in healthcare IT. During analysis secondary data has been used. Various articles and research papers published in national and international journals are used. India is hub of IT and its use is increasing in health sector.

The development of fundamentally new technology requires companies to carefully consider how they intend to profit from the commercialization of their ideas. Because companies pursuing disruptive innovations require new organizational capabilities and are often pushing into new markets with unproven technology, they must become masters in dealing with uncertainty. This thesis attempts to provide a holistic and rigorous process to systematically develop and evaluate options for profiting from the commercialization of disruptive technologies that are currently in the limited application stage of development. This thesis reviews the basic elements of technology commercialization, existing approaches to the value capture phase of technology strategy, the fundamental stages of the product development process, and the role of real options theory in addressing uncertainty. The author's experiences with the hydrogen industry provided further insight into the key difficulties in developing strategic options to capture value from the commercialization of disruptive technology. These difficulties include market and technical uncertainty, the infancy of the value chain, capabilities development, the development and valuation of specific strategic options, and the role of established processes, structure and culture of existing companies. This thesis describes a two part process to addressing these difficulties. The macro level process guides the company's strategy development process by emphasizing emergent strategy, the transition to complementary assets, and a focus on navigating the limited application phase of technology commercialization. The product specific strategy provides a rigorous process for exploring the value chain
(cont.) identifying sources of uncertainty, and developing specific options for capturing value from the disruptive innovation while emphasizing sound product development practices and requirements. This thesis builds upon the author's experiences at ChevronTexaco to illustrate the application of these concepts. In one case study, the product specific process is applied to the development of a stationary engine emissions control device. The application of this process revealed or verified significant product development risks while emphasizing that the target segment of the value chain was unlikely to be highly profitable. In another case study, a real options analysis is performed to examine the value of ChevronTexaco developing a near term limited manufacturing capability that would provide future strategic flexibility. The analysis demonstrated how an internal manufacturing capability might improve the probability of profiting from the commercialization of hydrogen fuel processing technology.

La complexité croissante des systèmes numériques amène les architectures reconfigurable telles que les Field Programmable Gate Arrays (FPGA) à être très fortement demandés en raison de leur facilité de (re)programmabilité et de leurs faibles coûts non récurrents (NRE). La re-configurabilité est réalisée grâce à de nombreux point mémoires de configuration. Cette re-configurabilité se traduit par une extrême flexibilité des applications implémentées et dans le même temps par une perte en surface, en performances et en puissance par rapport à des circuits intégrés spécifiques (ASIC) pour la même fonctionnalité. Dans cette thèse, nous proposons la conception de FPGA avec différentes technologies 3D pour une meilleure efficacité. Nous intégrons les blocs à base de mémoire résistives pour réduire la longueur des fils de routage et pour élargir l'employabilité des FPGAs pour des applications non-volatiles de faible consommation. Parmi les nombreuses technologies existantes, nous nous concentrons sur les mémoires à base d'oxyde résistif (OxRRAM) et les mémoires à pont conducteur (CBRAM) en évaluant les propriétés uniques de ces technologies. Comme autre solution, nous avons conçu un nouveau FPGA avec une intégration monolithique 3D (3DMI) en utilisant des interconnexions haute densité. A partir de deux couches avec l'approche logique-sur-mémoire, nous examinons divers schémas de partitionnement avec l'augmentation du nombre de couches actives intégrées pour réduire la complexité de routage et augmenter la densité de la logique. Sur la base des résultats obtenus, nous démontrons que plusieurs niveaux 3DMI est une alternative solide pour l'avenir de mise à l'échelle de la technologieThe ever increasing complexity of digital systems leads the reconfigurable architectures such as Field Programmable Gate Arrays (FPGA) to become highly demanded because of their in-field (re)programmability and low nonrecurring engineering (NRE) costs. Reconfigurability is achieved with high number of point configuration memories which results in extreme application flexibility and, at the same time, significant overheads in area, performance, and power compared to Application Specific Integrated Circuits (ASIC) for the same functionality. In this thesis, we propose to design FPGAs with several 3D technologies for efficient FPGA circuits. First, we integrate resistive memory based blocks to reduce the routing wirelength and widen FPGA employability for low-power applications with non-volatile property. Among many technologies, we focus on Oxide Resistive Memory (OxRRAM) and Conductive Bridge Resistive Memory (CBRAM) devices by assessing unique properties of these technologies in circuit design. As another solution, we design a new FPGA with 3D monolithic integration (3DMI) by utilizing high-density interconnects. Starting from two layers with logic-on-memory approach, we examine various partitioning schemes with increased number of integrated active layers to reduce the routing complexity and increase logic density. Based on the obtained results, we demonstrate that multi-tier 3DMI is a strong alternative for future scaling

The new generations of multi-core chipset architectures achieve unprecedented levels of computational power while respecting physical and economical constraints. The cost of this power is bewildering program complexity. Atmospheric modeling is a grand-challenge problem that could make good use of these architectures if they were more accessible to the average programmer. To that end, software tools and programming methodologies that greatly simplify the acceleration of atmospheric modeling and simulation with emerging multi-core technologies are developed. A general model is developed to simulate atmospheric chemical transport and atmospheric chemical kinetics. The Cell Broadband Engine Architecture (CBEA), General Purpose Graphics Processing Units (GPGPUs), and homogeneous multi-core processors (e.g. Intel Quad-core Xeon) are introduced. These architectures are used in case studies of transport modeling and kinetics modeling and demonstrate per-kernel speedups as high as 40x. A general analysis and code generation tool for chemical kinetics called "KPPA" is developed. KPPA generates highly tuned C, Fortran, or Matlab code that uses every layer of heterogeneous parallelism in the CBEA, GPGPU, and homogeneous multi-core architectures. A scalable method for simulating chemical transport is also developed. The Weather Research and Forecasting Model with Chemistry (WRF-Chem) is accelerated with these methods with good results: real forecasts of air quality are generated for the Eastern United States 65% faster than the state-of-the-art models.Ph.

Full textAbstract:
This paper attempts to chart potential courses for federal regulation of emerging technologies in the United States, and its near-future implications for the development and proliferation of NBIC technologies in a transhumanist context. Drawing on significant regulatory actions by the FDA and FCC throughout the twentieth century, relevant historical regulatory trends are identified and extrapolated broadly across the next two to three decades. The importance of the NBIC paradigm is discussed in detail, alongside several examples of both current and potential NBIC technologies with transhumanist applications. It ultimately concludes that, in spite of recent congressional dysfunctions and lack of political will, the groundwork that has already been laid by major federal regulatory agencies well in advance of the wide commercialization of NBIC products is a promising sign for the eventual establishment of responsible and flexible regulatory schema for NBIC technologies.

Essay I explores brain machine interface (BMI) technologies. These make direct communication between the brain and a machine possible by means of electrical stimuli. This essay reviews the existing and emerging technologies in this field and offers a systematic inquiry into the relevant ethical problems that are likely to emerge in the following decades. Essay II, co-written with professor Sven-Ove Hansson, presents a novel procedure to engage the public in ethical deliberations on the potential impacts of brain machine interface technology. We call this procedure a Convergence seminar, a form of scenario-based group discussion that is founded on the idea of hypothetical retrospection. The theoretical background of this procedure and the results of the five seminars are presented here. Essay III discusses moral enhancement, an instance of human enhancement that alters a person’s dispositions, emotions or behavior in order to make that person more moral. Moral enhancement could be carried out in three different ways. The first strategy is behavioral enhancement. The second strategy, favored by prominent defenders of moral enhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I argue that we ought to implement a combination of the second and third strategies.QC 20121206

A set of contracts guides every movement of cargo from one point to another. In this thesis, we focus on the contract between the charterer and the ship-owner in the liquid bulk ocean-shipping market. The contracting process begins with the two parties finding each other suitable and ends with one party being compensated in compliance with the terms and conditions of the contract for meeting a set of considerations. The question we answer is how emerging technologies, primarily Blockchain, can be used to make this process more efficient in terms of time and cost. Our research shows that while there are a considerable cost and time savings possible for certain aspects of the contracting process, there are some problem areas, such as the negotiations, that cannot be solved with the help of existing technology. We also conclude that the proposed solution needs to offer an end-to-end contract and document management tool rather than just being an improvement for one particular step in the process. An industry-wide consortium led Blockchain-based solution has potential to find wide acceptability and impact in terms of increased efficiency.

This study examined how and why faculty adopt podcasting as an instructional technology tool in their teaching. Podcasting is an instructional technology tool being used for teaching and learning in higher education. Faculty may record lectures with audio, video, and/or PowerPoint slides to instruct students on class material. Students may access podcasts at their convenience through various devices, including mobile devices and computers. Research has shown that students who use podcasts to study for tests tend to perform more successfully on tests. This study was a qualitative multiple case study of seven California community college faculty using podcasting as an instructional technology in their teaching. Email and telephone interviews were conducted to obtain data for this study. Rogers’ diffusion of innovations theory, and specifically the perceived attributes of innovation and their rate of adoption, was the theoretical framework used in this study to help explain how faculty develop attitudes and behavior toward podcasting as a teaching tool in higher education and to provide a context for faculty adoption of podcasting as a teaching tool in higher education. This study revealed seven themes that informed how and why faculty adopt podcasting in their teaching, as well as constraints to adopting podcasting. The seven themes identified in this research using Rogers’ perceived attributes of diffusion of innovations framework and their rate of adoption (PADIRA) are: (a) Apprehension, (b) Flexibility, (c) Organization, (d) Personal Gratification, (e) Student Outcomes, (f) Technological Capacity, and (g) Training. Given the demonstrated potential of podcasting technology for enhancing teaching and learning, this study of perceived benefits and constraints faced by California community college instructors when adopting podcasting in their classroom teaching has provided insights into instructional technology adaptation issues in higher education.

Full textAbstract:
In the quest for improved performance of buildings and mitigation of climate change, governments are encouraging the use of innovative sustainable building technologies. Consequently, there is now a large amount of information and knowledge on sustainable building technologies over the web. However, internet searches often overwhelm practitioners with millions of pages that they browse to identify suitable innovations to use on their projects. It has been widely acknowledged that the solution to this problem is the use of a machine-understandable language with rich semantics - the semantic web technology. This research investigates the extent to which semantic web technologies can be exploited to represent knowledge about sustainable building technologies, and to facilitate system decision-making in recommending appropriate choices for use in different situations. To achieve this aim, an exploratory study on sustainable building and semantic web technologies was conducted. This led to the use of two most popular knowledge engineering methodologies - the CommonKADS and "Ontology Development 101" in modelling knowledge about sustainable building technology and PV -system domains. A prototype system - Photo Voltaic Technology ONtology System (PV -TONS) - that employed sustainable building technology and PV -system domain knowledge models was developed and validated with a case study. While the sustainable building technology ontology and PV -TONS can both be used as generic knowledge models, PV -TONS is extended to include applications for the design and selection of PV -systems and components. Although its focus was on PV -systems, the application of semantic web technologies can be extended to cover other areas of sustainable building technologies. The major challenges encountered in this study are two-fold. First, many semantic web technologies are still under development and very unstable, thus hindering their full exploitation. Second, the lack of learning resources in this field steepen the learning curve and is a potential set-back in using semantic web technologies.

Os avanços da indústria de semicondutores nas últimas décadas foram baseados fortemente na contínua redução de tamanho dos dispositivos CMOS fabricados. Os usos de dispositivos CMOS dependem profundamente da lógica de portas E/OU/INV. À medida que os dispositivos CMOS estão atingindo oslimites fisicos, pesquisadores aumento esforço para prolongar a vida útil da tecnologia CMOS. Também é necessário investigar dispositivos alternativos, que em muitos casos implicam no uso de operações lógicas básicas diferentes. Como as ferramentas comerciais de síntese não são capazes de manipular eficientemente estas tecnologias Esta tese de doutorado foca em produzir algoritmos eficientes para projeto de circuitos tanto em CMOS quanto em novas tecnologias, integrando estes algorithmos em fluxos de projeto. Para esta tarefa, aplicamos a técnica da composição functional, para sintetizar eficiente tanto em CMOS quanto em tecnologias emergentes. A composição funcional é uma abordagem de síntese de baixo para cima, provendo flexibilidade para implementar algoritmos com resultados ótimos ou sub-ótimos para diferentes tecnologias. A fim de investigar como a composição funcional se compara às abordagens de síntese estado-da-arte, propomos aplicar esse paradigma de síntese em seis cenários diferentes. Dois deles se concentram em circuitos baseados em CMOS e outros quatro em circuitos baseados em tecnologias emergentes. Em relação a circuitos baseados em CMOS, investigamos a composição funcional para fatoração de funções multi-saídas, aplicadas em um fluxo de resíntese. Também manipulamos funções aproximadas, a fim de sintetizar módulos de redundância tripla aproximada. No que diz respeito as tecnologias emergentes, exploramos a composição funcional através de diodos spintrônicos e outras abordagens promissoras com base em diferentes implementações de lógica: a lógica de limiar, lógica majoritária e lógica de implicação. Resultados apresentam uma melhoria considerável em relação aos métodos estadoda- arte tanto para aplicações CMOS quanto aplicações de tecnologias emergentes, demonstrando a capacidade de lidar com diferentes tecnologias e mostrando a possibilidade de melhorar tecnologias ainda não exploradas.The advances in semiconductor industry over the last decades have been strongly based on continuous scaling down of dimensions in manufactured CMOS devices. The use of CMOS devices profoundly relies on AND/OR/Inverter logic. As the CMOS scaling is reaching its physical limits, researchers increase the effort to prolong the CMOS life. Also, it is necessary to investigate alternative devices, which in many cases implies the use of different basic logic operations. As the commercial synthesis tools are not able to handle these technologies efficiently, there is an opportunity to research alternative logic implementations better suited for these new devices. This thesis focuses on presenting efficient algorithms to design circuits in both CMOS and new technologies while integrating these algorithms into regular design flows. For this task, we apply the functional composition technique, to efficiently synthesize both CMOS and emerging technologies. The functional composition is a bottom-up synthesis approach, providing flexibility to implement algorithms with optimal or suboptimal results for different technologies. To investigate how the functional composition compares to the state-of-the-art synthesis methods, we propose to apply this synthesis paradigm into six different scenarios. Two of them focus on CMOS-based circuits, and other four are based on emerging technologies. Regarding CMOSbased circuits, we investigate functional composition to investigate multi-output factorization in a circuit resynthesis flow. Also, we manipulate approximate functions to synthesize approximate triple modular redundancy (ATMR) modules. Concerning emerging technologies, we explore functional composition over spin-diode circuits and other promising approaches based on different logic implementations: threshold logic, majority logic, and implication logic. Results present a considerable improvement over the state-of-the-art methods for both CMOS and emerging technologies applications, demonstrating the ability to handle different technologies and showing the possibility to improve technologies not explored yet.

Full textAbstract:
With CMOS technology scaling reaching its limitations rigorous research of alternate and competent technologies is paramount to push the boundaries of computing. Spintronic and resistive memories have proven to be effective alternatives in terms of area, power and performance to CMOS because of their non-volatility, ability for logic computing and easy integration with CMOS. However, deeper investigations to understand their physical phenomenon and improve their properties such as writability, stability, reliability, endurance, uniformity with minimal device-device variations is necessary for deployment as memories in commercial applications. Application of these technologies beyond memory and logic are investigated in this thesis i.e. for security of integrated circuits and systems and special purpose memories. We proposed a spintonic based special purpose memory for search applications, present design analysis and techniques to improve the performance for larger word lengths upto 256 bits. Salient characteristics of RRAM is studied and exploited in the design of widely accepted hardware security primitives such as Physically Unclonable Function (PUF) and True Random Number Generators (TRNG). Vulnerability of these circuits to adversary attacks and countermeasures are proposed. Proposed PUF can be implemented within 1T-1R conventional memory architecture which offers area advantages compared to RRAM memory and cross bar array PUFs with huge number of challenge response pairs. Potential application of proposed strong arbiter PUF in the Internet of things is proposed and performance is evaluated theoretically with valid assumptions on the maturity of RRAM technology. Proposed TRNG effectively utilizes the random telegraph noise in RRAM current to generate random bit stream. TRNG is evaluated for sufficient randomness in the random bit stream generated. Vulnerability and countermeasures to adversary attacks are also studied. Finally, in thesis we investigated and extended the application of emerging non-volatile memory technologies for search and security in integrated circuits and systems.

This study identifies substantive issues and suggests guidelines for using assistive technology (AT) in academic libraries. The Delphi Technique was used with a panel of librarians, disability service providers, and AT experts to determine these issues and guidelines for AT services in academic libraries. There were 55 substantive issues identified by a panel of experts for providing appropriate AT in an academic library setting. Some of these issues included training opportunities, providing adequate funding for the purchase and maintenance of AT, funding for staff in-service training and training for individuals with disabilities, evaluation of AT services, and including individuals with disabilities in AT decision making. Accessibility and marketing issues also emerged. A professional panel consisting of 12 library, AT, and disability services experts developed guidelines for these issues. The panel rated the desirability of the guidelines using a Likert-type scale (1= important, 2=relevant problem, 3= insignificantly relevant problem, and 4=no relevance). All issues and guidelines receiving two-thirds of the responding panelists' ratings were included in the important and relevant categories. It was predicted that if librarians plan AT services and training, and market AT services using a collaborative approach that would include librarians, faculty, staff and students with disabilities that AT services could be better provided for students with print disabilities. The panel suggested that funding issues may be resolved in some cases by working cooperatively with other departments and community agencies.Ph. D.

Full textAbstract:
The growing impact of online research communities and emerging technologies is creating a significant paradigm shift and consequently changing the current research landscape of higher education. The rise of online research communities exemplifies a shift from traditional research engagements, to online research communities using “Web 2.0,” in which communities of researchers are the basic unit of research engagement. As institutional practices become increasingly digitized, the role of faculty, scholars, and professionals are constantly reshaped and re-negotiated. The rise and use of emerging technologies in the field of research, has the potential to significantly impact the individual researcher, their institutions and ultimately the State. The project Critical Conversations Research Network is a part of a broader initiative undertaken by the Tennessee Board of Regents Office of Academic Affairs. TBR’s Critical Conversations for Jobs and the Economy is designed to complement Gov. Bill Haslam’s “Drive to 55” initiative, which aims to bring the percentage of Tennesseans with college degrees to 55 percent by the year 2025. (Haslam, 2013). The initiative undertaken by TBR’S office of Academic Affairs consists of: (a) Conversational interviewing of selected scholars and researchers across TBR institutions through video recordings of important and critical research topics that affect policy implications in the state of Tennessee, (b) an interdisciplinary journal called Critical Conversations Interdisciplinary Journal (CCIJ) dedicated to promoting dialogue on topics of importance among scholars across disciplines at TBR institutions. The journal provides a platform for critical conversations through which all disciplines can inform practice and practice can inform all disciplines, providing guidance for future public policy decisions and (c) the proposed Critical Conversations Research Network which is the focus of this paper. The goal of the Tennessee Board of Regents Critical Conversations Research Network (“TBR’s-CCRN”) is to connect TBR’s faculty, researchers and scholars in collaboration, dialogue and engagement, about pertinent research initiatives undertaken by individuals and institutions across the state. A secondary purpose is to highlight the practical implications of research for economic and workforce development and to assist policymakers to engage in data-driven and informed decision-making.

Full textAbstract:
My research is a practice-based project involving documentary production and theoretical analysis of emerging forms of documentary and online co-collaboration, exploring paradigm shifts in digital technology particularly in the web-based feminist activism and feminist social praxis. The practice-led research explores new forms of production practices outside traditional methodologies and dissemination. Specifically, by utilizing cheap digital technology tools and working within online social networking platforms the research theoretically analyses what means were available towards online participatory media practices to create new documentary forms. My research aims are therefore to investigate how the new paradigm shifts in digital technology and the democratization of the filmmaking process, through online, collaborative practice, can allow women documentary filmmakers to connect to a global marketplace outside the traditional filmmaking channels. Further, looking at the history of the documentary form, as well as the feminist movement, I am interested in which of the key themes and debates that have characterized their intersection are still important at this moment of changing and emerging technologies. Can new technologies, access to cheap digital tools and collaborative modes of practice help or hinder the creative process of making a digital documentary? In examining the history of feminist filmmaking and the emerging documentary shifts in production offered the opportunity to position my own practice within these traditions and experiment further with online forms of modality. This experiment allowed me to gather empirical data using new media practices (i.e. creation and curation of online and repurposed content, use of new production tools within online spaces) to create a first person, auto-ethnographic narrative on the subject of feminism and online activism. Additionally, my research looks at the theoretical and historical underpinnings surrounding feminist filmmaking, new documentary practices and its implications within new technologies, and the emerging forms of collaborative online modes of practice. Each of these areas will intersect within the three key areas of debate surrounding documentary filmmaking; those of 1) narrativity, 2) witness and 3) ethics. My practice investigates these interactive, participatory modes created with emerging technologies and online audiences and how this is shifting narratives, audience reception and producing new ethical debates around ‘truth' and ‘authenticity' as these lines are continually blurred. Rethinking documentary in the virtual space brings about new challenges to the old debates around evidence, witness and ethics, as it is the product of a more democratic attitude towards practice, distribution and dissemination of its stories. New participatory audiences are now also helping to create the very product they are witnessing. Therefore, creating media within the public sphere can bring about a wealth of new tools, wider contributions to media making and a more global awareness of its dissemination. But it is not without its controversy and challenges. Further, my research looks at how working within this co-collaborative mode, the position of filmmaker as the ‘sole' creator or ‘auteur' comes into question. It discuses the advantages and/or the disadvantages to this approach and in doing so looks at what contributions and challenges an online audience can provide to support the filmmaker that cannot be gained through historical and traditional production and exhibition forms. What once was a higher barrier to entry into the film business is now a more open and online accessibility where anyone can wield a cheap camera or mobile phone device, make a movie and share it on the internet. These newfound democratic practices could potentially disrupt an already complex system of communication practices. However, it could also supply it with a much-needed collective idea bank for tackling global issues and finding sustainable solutions. Within the scope of participatory practices, a first person filmmaker can experience the greatest of democratic freedom within the confines of this process and delivery. The research is supported and conducted through a practice-led film project, web support platform (including blog and social media sites) and published case study. The final output film project around which these questions are posed is entitled: “Single Girl in a Virtual World: What does a 21st Century Feminist Look Like?”. The film's purpose is therefore to engage an online global audience of participants and contributors to the film's narrative thread by asking for contributions within the production, creation and financing of the documentary film. The practice utilizes social networks, crowd funding initiatives, web blogs, viral video, virtual chat interaction and traditional modes of documentary practice in its methodology in an effort to collect data surrounding activity and attempt to answer my research questions at large. The overall objective is to create an online documentary film that exemplifies feminist activism in a new frame through application of documentary modes and new emerging digital media practices.

Technology is continuously being developed, processed and created into products for the consumer market; however, in the steps of this process, there is often one goal in mind, and using the technology is rare used for different and novel areas. The goal of this paper is to show how three emerging technologies can be used creatively beyond their original purposes by the sports industry. The technologies addressed in the paper are The Microsoft Full Body Network, ShapeTape and the FluidFocus Lens. These technologies address the issues of wireless data and power transmission, data acquisition, and the creation of a lens with variable focus with no mechanical or moving parts, respectively. Research was done to understand the current state of the technology or product, and what obstacles remain in the path to the creation of an actual working prototype. A merging of these three technologies resulted in a proposed product for the sports industry. The name, Wired Skin, was given to this envisioned product, and was tailored in response to a survey conducted with a pool of 200 individuals. The issues of the price range customers were willing to spend on various products, the importance of various improvements to existing technology and general questions to specify the demographic questioned were addressed fully. This paper creates a melding of the three technologies into a product that addresses the major barriers to the entrance of emerging technology to the area of athletics.

This thesis explores the quantification of transportation technology benefits, through simultaneous consideration of technical and policy issues. Benefits are first defined and identified based on current literature and discussions. Key benefits include delay impacts, safety impacts and environmental concerns. A key element of such quantification and analysis is traffic simulation. MITSIMLab, a microscopic traffic simulator, has been recently enhanced to replicate transportation technologies and applications such as traffic signal priority and advanced vehicle location for transit. In addition, the existing capability for modeling incident detection and management is reviewed. These applications are tested on a traffic network on Stockholm, Sweden, about to undergo new construction and development. The implementations are demonstrated to be effective in a quantitative and qualitative manner, and successful in illustrating the benefits of signal priority for transit as well as the integration of different technologies in the simulation itself. Through the case study, this capability is contrasted with the ability of MITSIMLab to depict impacts of infrastructure changes. Benefits quantification is discussed through post-processing MITSIMLab output measures such as travel time statistics. Benefits evaluation is necessarily intertwined with policy development. The technical analysis of the Stockholm network is framed with an investigation of transportation policy issues in the US and Sweden. Fundamental policy issues of stakeholder cooperation, technical integration and regional integration are identified, then explored in the context of benefits evaluation.

Novartis Vaccines (NV) in Liverpool operates an egg-based, semi-automated, influenza vaccine manufacturing facility with the capability to process a batch per day. This thesis focuses on the Agrippal base product, an inactivated subunit trivalent vaccine. The objectives of this multidisciplinary project included optimisation of assays and introduction of analytical technologies that could potentially facilitate characterisation of viral concentration, particle size and aggregation interactions with a view to promote understanding of product stability and identify opportunities for process optimisation and yield improvements in the Agrippal platform. The first phase of this project focused on methods of nanoparticle analysis that could enable efficient monitoring of viral content from the early stages of product development and throughout the downstream operations. A comparative evaluation between commonly used particle analysers showed that differential centrifugal sedimentation (DCS) is the most suitable method for the analysis of in-process influenza vaccine samples. Novel applications of DCS throughout the manufacturing of egg-based inactivated influenza vaccines were examined and are reported herein. DCS was proven to be a valuable analytical tool by demonstrating high potential for process investigation and monitoring. Key applications include direct determination of viral content in allantoic fluid, viral quantification at whole virus process stages, characterisation of unit operations on a particle based approach and detection and monitoring of the kinetics of aggregation. Furthermore, DCS was specifically employed in a novel study entailing direct determination of influenza virus growth in allantoic fluid upon addition of glucocorticoids and other compounds (hydrocortisone, dexamethasone, corticosterone, AFZ077 and BYF589) into the viral seed inoculum. Additionally, the intricate, multi-step, multi-variable and poorly characterised solubilisation process of the membrane glycoproteins Haemagglutinin (HA) and Neuraminidase (NA) from the surface of influenza virus by the detergent CTAB, as applied in the Agrippal manufacture platform, was comprehensively examined with the aim of enhancing process understanding by identifying the key parameters potentially affecting solubilisation efficiency and product quality. Finally, the development and optimisation of a novel GNA-binding enzyme-linked immunosorbent assay (ELISA) as an alternative replacement to the Single Radial Immunodiffusion (SRID) potency assay for quantification of HA in vaccine samples is described.

Full textAbstract:
In order for a photovoltaic device to be commercially viable it must have a production cost and operational stability commensurate with its final application. Both of these properties are influenced by many factors, including the production of the active materials and the deposition techniques used to fabricate it. In this thesis, the stability and manufacturability of two emerging photovoltaic materials are examined: organic semiconducting polymers and organic-inorganic perovskites. Organic semiconducting polymers are commonly synthesised through reactions utilising metal catalysts, which can remain with the polymer after synthesis, necessitating the investigation of their influence on photovoltaic devices. This work shows that the presence of the residual catalyst palladium in PCDTBT organic photovoltaic (OPV) devices caused significant reductions in power conversion efficiency and an additional increase in efficiency loss during the first 60 hours of operation. It is also shown, however, that only minor losses occurred in PFD2TBT-8 OPV devices at high Pd concentrations, highlighting the need to examine individual material systems. Despite being a very new technology, perovskite solar cells (PSCs) have already achieved comparable performance to silicon solar cells, making it important to investigate the stability of such devices. The operational stability of PSCs in the inverted architecture was characterised, showing lifetimes of < 300 hours. Using spectroscopic and device characterisation techniques, the major loss mechanisms were revealed to be reactions with water and oxygen, resulting the in the decomposition of the perovskite. It is also examined how the addition of hydroiodic acid to the perovskite precursor solution affects the performance and stability of spin and spray coated PSCs. Finally, the effects of deposition temperature and additional annealing on the operational stability of PSCs was investigated.

Full textAbstract:
Innovative teaching is, in essence, the art of breaking down barriers which prevent educators from preparing learners for the gruelling demands of the 21st century by exploiting the affordances of emerging Information and communications technologies (ICT) to enhance their teaching and learning strategies. The resulting new educational practice can affect roles, learning situations, patterns of interaction, learning spaces, strategies and theories as well as modes of assessment (Mioduser, Nachmias, Tubin,&Forkosh-Baruch, 2002a). The problem addressed in this study is that of innovative teacher knowledge construction and its context. The role of educational technologies in teaching and learning has evolved and changed dramatically over time but little is understood of how this knowledge manifests itself in their practice and how it is replicated and shared in practice. Pioneering, innovative teachers have developed personal theories that may potentially inform future practice once articulated and disseminated. This study sets out to deepen our understanding of how new knowledge is created in practice by innovative teachers and how this knowledge manifests itself in teaching and learning with emerging ICT. The consequent collaboration between researcher and participant teachers can act as a reconciliatory measure between practice and theory. The literature reviewed draws on tenets from socio-cultural theory, critical philosophy, emerging technology and teaching and learning theory and aims to construct rational foundations to assist in the articulation of new theories which, in turn, will better our understanding of this new emerging pedagogical practice. A post-modernistic interpretive prism views the research investigation through the work of teachers qualified as finalists in the Microsoft Innovative Teachers Forum Awards (ITFA) competition. This annual competition recognises and connects innovative teachers who share a common interest in the enhancement of teaching and learning through the use of technology. Data collecting instruments include metadata consisting of educational multimedia artefacts, virtual classroom tours (VCT’s), document analysis, innovative teacher workshops and interviews. The data were qualitatively analysed using Straussian Grounded Theory Method to articulate a substantive theory which aims to better our understanding of knowledge creation when innovative teachers use emerging technology to enhance their teaching and learning. The resultant substantive theory’s three core components comprise moral cohesion; innovation negotiations in context; and responsive governance as essential to innovative teachers’ pedagogical efficacy when they engage with emerging technologies. Innovative teachers’ perception of the professional burden they carry along with their bricoleur attitude allude to them using whatever means and whatever is at hand to equip learners with the skills required to make them contributing members of their community and the information society. Strategies for the constant renewal of pedagogical practices and the need for reflexivity included the appropriation of learners’ personal devices for learning where their disposition had to be carefully managed in accordance with ethical considerations and their various capabilities. Innovative teachers are powerful change agents within their school environments and in this regard a certain amount of freedom could be offered to innovative teachers to further explore their own practice whilst at the same time tasking them with additional responsibilities in growing organisational capabilities. Innovative teachers use their increased status and power within their schools to actively lobby for policy changes through participating in advisory committees and assisting in the drafting of documents that hold strategic, ethical and practical implications for the exploitation of emerging technologies within their schools.Thesis (PhD)--University of Pretoria, 2011.

Full textAbstract:
The reversible logic has promising applications in emerging computing paradigms, such as quantum computing, quantum dot cellular automata, optical computing, etc. In reversible logic gates, there is a unique one-to-one mapping between the inputs and outputs. To generate a useful gate function, the reversible gates require some constant ancillary inputs called ancilla inputs. Also to maintain the reversibility of the circuits some additional unused outputs are required that are referred to as the garbage outputs. The number of ancilla inputs, the number of garbage outputs and quantum cost plays an important role in the evaluation of reversible circuits. Thus minimizing these parameters are important for designing an efficient reversible circuit. Reversible circuits are of highest interest in optical computing, quantum dot cellular automata and quantum computing. The quantum gates perform an elementary unitary operation on one, two or more two-state quantum systems called qubits. Any unitary operation is reversible in nature, and hence, quantum networks are also reversible, to conclude the quantum computers must be built from reversible logic components.
The main contribution of this dissertation is the design exploration and application of reversible circuits in emerging nanotechnologies. The emerging technologies explored in this work are 1) Optical quantum computing 2) Quantum computing.
The first contribution of this dissertation is Mach-Zehnder interferometer based design of all optical reversible binary adder. The all optical reversible adder design is based on two new optical reversible gates referred as optical reversible gate I (ORG-I) and optical reversible gate II (ORG-II) and the existing all optical Feynman gate. The two new reversible gates ORG-I and ORGI-II have been proposed and can implement a reversible adder with a reduced optical cost which is equal to the number of MZI switches required, less propagation delay, and with zero overhead in terms of number of ancilla inputs and the garbage outputs. The proposed all optical reversible adder design based on the ORG-I and ORG-II reversible gates are compared and shown to be better than the other existing designs of reversible adder proposed in the non-optical domain in terms of number of MZI switches, delay, the number of ancilla inputs and the garbage outputs. The proposed all optical reversible adder will be a key component of an all optical reversible arithmetic logical unit (ALU), that is a quite essential component in a wide variety of optical signal processing applications. In the existing literature, the NAND logic based implementation is the only known implementation available for reversible gates and its functions. There is a lack of research in the direction of NOR logic based implementation of reversible gates and functions. The second contribution of this dissertation is the design of NOR logic based n-input and n-output reversible gates, one of which can be efficiently mapped into optical computing using the Mach-Zehnder interferometer (MZI), while the other can be mapped efficiently in optical computing using the linear optical quantum gates. The proposed reversible NOR gates work as a corresponding NOR counterpart of NAND logic based Toffoli gates. The proposed optical reversible NOR logic gates can implement the reversible boolean logic functions with less number of linear optical quantum logic gates with reduced optical cost and propagation delay compared to the implementation using existing optical reversible NAND gates. It is illustrated that an optical reversible gate library having both optical Toffoli gate and the proposed optical reversible NOR gate is superior compared to the library containing only the optical Toffoli gate: (i) in terms of number of linear optical quantum gates when implemented using linear optical quantum computing (LOQC), (ii) in terms of optical cost and delay when implemented using the Mach-Zehnder interferometer. The third contribution of this dissertation is a binary tree-based design methodology for a NxN reversible multiplier. The proposed binary tree-based design methodology for a NxN reversible multiplier performs the addition of partial products in parallel using the reversible ripple adders with zero ancilla bit and zero garbage bit; thereby, minimizing the number of ancilla and garbage bits used in the design. The proposed design methodology shows improvements in terms of number of ancilla inputs and garbage outputs compared to all the existing reversible multiplier designs. The methodology is also extended to the design of NxN reversible signed multiplier based on modified Baugh-Wooley multiplication methodology.

Full textAbstract:
Technological developments open new opportunities to meet the increasing expectations of visitors to galleries, libraries, archives or museums. Although these technologies provide many new possibilities, individual challenges and limitations are rife. Galleries, libraries, archives and museums should aim to unify many such technologies in order to capture visitor attention, engage interaction and facilitate both personal and social experiences. By incorporating objects, devices and people into a network of interconnected systems, new patterns, interaction types and social relations are expected to emerge. This thesis explores the unification of these technologies, identifies behavioural patterns emerging from visitor interactions and examines how combining these technologies can contribute to engaging visitor interactions and the effects they have on both individuals and groups. The thesis states that combining mobile devices and interactive displays will offer new engaging interactions for museum visitors. This will allow them to spread their interactions throughout the museum and easily switch between private and social experiences. Museums should therefore adopt combinations of mobile devices and interactive displays to meet the increasing expectations of their visitors and offer both private and social experiences.

Full textAbstract:
This work investigates the elimination of new and emerging microcontaminants (EMs) from water by means of photochemical oxidation processes, namely heterogeneous and homogeneous photocatalysis. Representative compounds of artificial sweeteners (saccharin, SAC), endocrine disruptors (bisphenol-A, BPA), and pharmaceutica ls (antipyrine, AP) of high environmental persistence and widespread occurrence in the water cycle are used as case studies. Novel concepts that can make photochemica l oxidation a more cost-effective and environmentally benign technology are tested. In Chapter 4, the photocatalytic treatment of SAC and BPA is investigated. Novel submicronic anatase-rutile nanocomposite particles with tuned phase ratio are used as catalysts to increase the photocatalytic performance under UVA irradiation. At the best-assayed conditions (C0 = 3 mg/L, catalyst = 400 mg/L), SAC and BPA are completely degraded within 90 and 150 min of photocatalytic treatment, respectively. [variables: anatase-rutile ratio; initial substrate concentration; catalyst concentration; catalyst reuse; sonication during catalyst recovery] In Chapter 5, a UVA light-emitting diode (UVA-LED) and sunlight are used as irradiation sources to reduce energy requirements and environmental impacts of photocatalytic processes. The photocatalytic degradation of SAC and BPA is studied under UVA irradiation provided by either a UVA-LED or a conventional fluoresce nt blacklight UVA lamp (UVA-BL) and solar irradiation. At the best-assayed conditions (C0 = 2.5 mg/L, TiO2 = 250 mg/L), BPA is completely degraded within 20, 30, and 120 min under UVA-LED, solar, and UVA-BL irradiation, respectively. The treatment time required for the complete elimination of SAC is 20 min under UVA-LED and 90 min under UVA-BL irradiation. [variables: initial substrate concentration; catalyst concentration; water matrix; light source; reactor configuration] In Chapter 6, a comparative study is carried out among the photocatalytic systems of Chapters 4 and 5 in terms of EMs removal, photonic and energy efficiencies. Technica l and economic aspects of all the processes are assessed. LED-driven photocatalysis achieves the highest efficiency in terms of organic removal with the minimum energy consumption, rendering it the most sustainable technology for the treatment of EMs. In Chapter 7, olive mill wastewater (OMW) is used as an iron-chelating agent in the photo-Fenton reaction to obviate the need for water acidification at pH 2.8. Conventional, OMW- and EDDS-assisted photo-Fenton treatment is applied for SAC degradation in a solar compound parabolic collector (CPC). It was found that OMW forms iron complexes able to catalyse H2O2 decomposition and generate hydroxyl radicals. At the optimal OMW dilution (1:800), 90% of SAC is degraded within 75 min. [variables: pH; iron-chelating agent; initial SAC concentration; OMW dilution] In Chapter 8, other complexing and oxidising agents, namely oxalate and persulfate, are used for the intensification of AP degradation during UVA-LED photo-Fenton treatment. Neural networks are applied for process modelling and optimisation. At the optimal conditions (hydrogen peroxide = 100 mg/L, ferrous iron = 20 mg/L, oxalic acid = 100 mg/L), complete degradation of AP and 93% mineralisation is achieved within 2.5 and 60 min, respectively. [variables: initial concentration of hydrogen peroxide, ferrous iron, oxalic acid, persulfate] It is concluded that LED-driven photocatalysis is a sustainable technology for the elimination of EMs from water. Results from this work highlight the need for development and optimisation of engineering proper LED reactors. Furthermore, this work introduces a new concept towards the sustainable operation of photo-Fenton that is based on the use of wastewaters rich in polyphenols instead of pricey and hazardous chemicals for iron chelation. The addition of ferrioxalate complexes is proposed for the intensification of EMs mineralisation during UVA-LED photo-Fenton treatment. Finally, the findings of this work encourage the use of chemometric tools as predictive and optimisation tools.

Abstract
Digital libraries represent the latest and perhaps the most important stage in the
transformation of our relationship to information and its supporting technologies. While
the World Wide Web has raised to broad consciousness the ideas of rapid, remote access
to vast collections of distributed, hyperlinked documents, users are as often confused and
disoriented by such resources as they are empowered. As we enter the new millennium
the possibilities for new forms of information seem boundless. Meeting the design
challenges requires HCI to offer valid, reliable and timely guidance. At the same time,
the creation of digital libraries provides a research forum for HCI that is rich, relevant
and receptive to our inputs. The present chapter will briefly examine the initiation of the
digital library concept, the early HCI involvement in this domain and present a vision of
the future of HCI research and design for new information technologies.
