The purpose of the study was to explore the application of the strengths, opportunities, aspirations, and results (SOAR) framework derived from the appreciative inquiry literature and through the lived experiences of California-based association management and non-profit executives leading professional societies, trade associations, or foundations. In addition, this research, using phenomenological interviewing techniques, aimed to determine whether or not association management executives working in California-based professional societies and trade associations changed their individual thought processes or behaviors as a result of attending a professional development program that demonstrated the SOAR framework. The research questions that guided this research were: (a) what changed mindsets were experienced as a result of an understanding with the SOAR framework in the strategic thinking process? and (b) what changed mindsets and organizational application were experienced as a result of an understanding with the SOAR framework in the strategic thinking process?

This qualitative study, using semi-structured interview questions, sought to explore and document the experiences of California-based senior association management executives with SOAR framework. This research aimed to add to the body of knowledge of SOAR as a result of expanded individual and organizational application of this approach as compared to other strategic thinking experiences. The study documents comparisons, by the non-profit executives involved in this study, between the more commonly known strategic thinking of strengths, weaknesses, opportunities, and threats (SWOT) analysis and the positivity-focused SOAR framework.

The aim of the study is to capture and understand the perceptions of SMEs with regard to the resources that they feel are missing as they engage in the process of internationalisation. The methodology of this study follows a qualitative method wherein four SMEs were interviewed along with an industry expert using semi-structured interviews. The collated data was processed according to academic procedure outlined by Creswell & Creswell (2018). Thereafter, the categorised data was analysed using an adapted situational analysis inspired by the SOAR Framework to identify missing resources. Findings and Conclusion: SMEs from Gävleborg, Sweden wish to internationalise but face extensive barriers caused by the lack of necessary resources. The empirical findings align with existing literature in identifying a lack of financial, human, and intellectual resources among the SMEs. However, the findings reject theories which cited a lack of financial skills and physical resources as causal factors. The framework presented (Figure 3) was found to be useful for academics, in reality the SMEs in the Gävleborg region follow a different approach. Contribution of the Study: This study adds specific insights and knowledge about the resource gaps experienced by Swedish SMEs to the literature. The outcomes indicate significant obstacles facing SMEs in the early or pre-internationalisation stage. Practical recommendations from this study suggest regional development of mentoring, accessible funding, and networking support. Reflections on the Study and Suggestions for Future Research: The Covid-19 pandemic forced all interviews online but zoom recordings facilitated clear and accurate collection of empirical evidence. For the future, a longitudinal study of SMEs in Sweden comparing resource availability by region and/or by firm size merits investigation. Similarly, research into why the resource gaps among SMEs remain an issue would be a welcome addition to resource-based literature.

Annotation:

A framework that presents a new methodology for design-evaluation of active solar collection systems was developed. Although this methodology emphasizes the importance of detailed modeling for accurate prediction of building performance, it also presents a process through which the detailed modeling results can be reused in a simplified iterative procedure allowing the designer the flexibility of revising and improving the preliminary design. For demonstration purposes, the framework was used to design and evaluate two case studies located in Blacksburg (VA) and Minneapolis (MN). These locations were selected because they both represent a cold weather region; presenting a need for using solar energy for heating and hot water requirements. Moreover, the cold weather in Blacksburg is not as severe as in Minneapolis. Therefore, the two cases will result in different thermal loading structures enabling the framework validation process. The solar collection system supplying both case studies consisted of a low temperature flat plate solar collector and storage system. Thermal performance of the case study located in Blacksburg was conducted using detailed modeling evaluation techniques; while thermal performance of the case study located in Minneapolis was conducted using a simplified modeling evaluation technique. In the first case study, hourly evaluation of the thermal performance of the solar collection system was accomplished using finite element (FE) analysis, while hourly evaluation of the building thermal performance was made using Energy Plus software. The results of the finite element analysis were used to develop a statistical predictive design equation. The energy consumption for the second case study was calculated using the heating design day method and the energy collection for that case study was calculated using the predictive design equation developed from the first case study results. Results showed that, in the case of the building located in Blacksburg, the solar collection system can supply an average of 85% of the buildingâ s heating and hot water requirements through out the year. In the case of the building located in Minneapolis, the solar collection system can supply an average of 56% of the buildingâ s heating and hot water requirements through out the year given no night time window insulation and using similar insulation thicknesses for both cases.

Annotation:

The widely accepted standards of Service-Oriented Architecture (SOA) have changed the way many organisations conduct their everyday business. The significant popularity of mobile devices has seen a rapid increase in the rate of mobile technology enhancements, which have become widely used for communication, as well as conducting everyday tasks. An increased requirement in many businesses is for staff not to be tied down to the office. Consequently, mobile devices play an important role in achieving the mobility and information access that people desire. Due to the popularity and increasing use of SOA and mobile devices, Mobile Service-Oriented Architecture (Mobile SOA) has become a new industry catch-phrase. Many challenges, however, exist within the Mobile SOA environment. These issues include limitations on mobile devices, such as a reduced screen size, lack of processing power, insufficient processing memory, limited battery life, poor storage capacity, unreliable network connections, limited bandwidth available and high transfer costs. This research aimed to provide an elegant solution to the issues of a mobile device, which hinders the performance of Mobile SOA. The main objective of this research was to improve the effectiveness and efficiency of Mobile SOA. In order to achieve this goal, a framework was proposed, which supported intelligent compression of files used within a Web Service. The proposed framework provided a set of guidelines that facilitate the quick development of a system. A proof-of-concept prototype was developed, based on these guidelines and the framework design principles. The prototype provided practical evidence of the effectiveness of implementing a system based on the proposed framework. An analytical evaluation was conducted to determine the effectiveness of the prototype within the Mobile SOA environment. A performance evaluation was conducted to determine efficiency it provides. Additionally, the performance evaluation highlighted the decrease in file transfer time, as well as the significant reduction in transfer costs. The analytical and performance evaluations demonstrated that the prototype optimises the effectiveness and efficiency of Mobile SOA. The framework could, thus, be used to facilitate efficient file transfer between a Server and (Mobile) Client.

Includes bibliographical references (p. 88-92).
The demand for Saudi oil is increasing locally and internationally, and being one of the major oil exporters in the world, the government of Saudi Arabia needs to balance between local consumption and international demand. To address this challenge, Saudi Arabia is adopting an aggressive strategy to use solar energy instead of oil to generate electricity. This strategy creates an opportunity to diversify the country's GDP by building solar manufacturing industry. This thesis uses the Enterprise Architecture Framework, developed by Nightingale and Rhodes, to propose the optimal architecture for the Saudi solar manufacturing in terms of organization, policy, strategy, product, services, infrastructure, and R&D. The first stage of the framework identifies the landscape and the major stakeholders in the solar manufacturing, and then studies the current situation of the Saudi solar manufacturing. The second stage analyzes the different proposed architectures. The third stage evaluates the different architectures, and the fourth stage selects and validates the winning architectures. The evaluation criteria for the different proposed architectures are based on three angles: "Attractiveness", which measures the level of compatibility between the architecture and the needs of the Saudi government. The "Effort", measures the human and financial effort required to deploy the architecture. The "Risk", which measures the different risks associated with the architecture. The winning architecture encourages Saudi businessmen to acquire international companies along with building local manufacturing for products in the lower end of the solar manufacturing value chain. The strategy in this architecture is to build fast capabilities in the technology and process side by acquiring international companies and steady capabilities in the production side by gradually moving up in the value chain. Also, the architecture proposes focusing and building the local R&D capabilities to improve the productivity, and profitability of the solar manufacturing companies.

Annotation:

Les communautés virtuelles ont de plus en plus d’influence dans nos activités quotidiennes. Qu’elles soient sociales, d’affaires, professionnelles, d’apprentissage, ces communautés sont en concurrence pour la conquête de l'Internet, en ciblant une audience de plus en plus large et en proposant une offre de services de plus en plus variée. Par voie de conséquence, le succès ou l'échec de ces communautés dépend largement des services proposés dont la diversité, la qualité et l'adaptation sont les facteurs clés de satisfaction des clients. C’est pourquoi la démarche SOA (Service Oriented Architecture /Architecture Orientée Service) favorise la vision d'environnements ouverts où services, fournisseurs et clients sont indépendants les uns des autres, grâce au découplage et à l'allocation dynamique des services. Malheureusement, les environnements de communautés virtuelles ne prennent pas vraiment en compte les principes SOA et sont considérés fermés d’un point de vue des services offerts car ceux-ci sont limités aux fonctionnalités de la plateforme qui les hébergent. Cette dépendance des services vis-à-vis de la plateforme est considérée comme une limitation qui influence d'une manière négative le succès et la durabilité des communautés virtuelles. Du point de vue des membres d’une communauté, cette limitation entraine le départ de certains d’entre eux, et/ou impose à ses membres de joindre d'autres communautés afin de bénéficier des services offerts par ces dernières qui ne sont pas disponibles dans leur communauté d'origine. Du point de vue de l’environnement, l'introduction de nouveaux services nécessite de modifier la plateforme existante, et peut demander dans certains cas une migration vers une autre plateforme, ce qui peut perturber la communauté en question lorsque celle-ci est opérationnelle avec des membres en ligne. Dans ce contexte, ce travail a pour but de palier les limites de la gestion de services dans les communautés virtuelles afin de satisfaire les besoins de leurs membres, d'assurer une meilleure gestion des services d'un point de vue individuel et d'un point de vue de la communauté, et de garantir une évolution dynamique des services au sein de la communauté. L’objectif principal est donc de " Fournir le bon service, au bon utilisateur, au bon moment et avec la bonne qualité". L’hypothèse fondatrice de ce travail est que les communautés virtuelles peuvent être construites en commençant par un ensemble minimal de services de base, cet ensemble pouvant ensuite être étendu par l'ajout de nouveaux services selon les besoins des membres de la communauté. En adoptant cette approche, nous proposons un cadre de gestion de services qui aborde les difficultés rencontrées par les communautés virtuelles et leurs membres. En conséquence, le focus porte sur la satisfaction de ces membres plutôt que sur le service lui-même ou le fournisseur du service. Ainsi, nous définissons une nouvelle structuration des services au sein d’une communauté qui s’appuie sur une classification en différentes catégories fonctionnelles. Puis, nous étendons l'architecture SOA avec les concepts nécessaires pour modéliser ces catégories et leur associer un ensemble de propriétés non fonctionnelles de Qualité de Service (QdS ou QoS en anglais) utilisées par un système de médiation pour proposer les services adaptés aux besoins des usagers. Une description des unités fonctionnelles de ce système, ainsi que la façon dont elles opèrent, coopèrent et collaborent afin d'accomplir l’objectif défini ci-dessus constitue le cœur de notre contribution
Virtual Communities are dominating our daily activities from different insights. Social, Business, Professional, Educational and many virtual communities are competing among each other to conquer the internet by targeting more audience through the services they provide. Consequently, the success or failure of virtual communities depends to a great extent on its services. In a world driven by services, diversity, quality and adaptation are key factors to achieve customer satisfaction. Accordingly the Service Oriented Architecture (SOA) approach promotes the vision of open environments where services, providers and consumers are considered independently from one another thanks to decoupling and dynamic allocation of services. But virtual communities environment did not really care about SOA and are considered closed with respect to the services they provide since they are bounded to the capabilities of the platform that host them. This implies the delivery of services inside the virtual communities is dependent on the platform used which is considered a limitation that have negative influence on the success and sustainability of virtual communities. From a member perspective this limitation causes community members to leave the community, and/or imposes them to join other virtual communities to benefit from the services they host and that are not available in their home virtual communities. From an environment perspective, introducing new services into these communities require modifications on the existing platforms or might require a complete shift to another platform in some cases which might affect the target community in case it is operational with active users. In this context, our research work aims to overcome the limitation in managing services of virtual community to satisfy community members’ needs, to provide better service management from a member perspective as well as from a community perspective, and to guarantee dynamic evolution of services inside the community. Our main objective is “To provide the right service to the right user in the right time with the required quality of service”. Our assumption is that virtual communities can be built starting from a minimal set of basic services and then add more services based on the needs of the community members. This drives us to adopt this approach and propose a service management framework that address the challenges faced by virtual communities and their members. Accordingly, we approach the problem from a members’ perspective and choose to work on members’ satisfaction more than we care about the service itself or the provider of the service. Thus, we define a new structure of services within a community that is based on a classification into different functional categories. Then, we extend SOA with the concepts necessary to model these categories and associate a set of non-functional properties of Quality of Service (QoS ) used by a mediation system to offer services best suited to the needs of members. Finally, we provide a description of the functional units of the system and how they operate, cooperate and collaborate to achieve the aforementioned objective. This is the core of our contribution

The constant evolution of technologies used in mobile devices has increased its capabilities with respect to its storage, processing and transmission of data, including more of one kind of technology transfer in a single device, and also access Internet more efficiently. These factors have a greater number of applications and services may be provided therein. With this came the need to find a model for developing services and making them available more quickly and efficient, and that data is transmitted more securely. One of the best options currently existing are the SOAS (Services Oriented Architecture) a development model in great evidence today. The aim of this dissertation is present a framework that allows the development of SOA in the mobile environment, giving the developer all the tools necessary for provision of services in this type of environment. A tool for the use of security mechanism for the Framework is also proposed.

Annotation:

The typical user base for computer applications has transformed, over time, from mostly technically oriented individuals to include a vast range of the worldâ s population - the majority of whom have little to no technical proficiency. As such, user interfaces have evolved from text-based shell input into multimedia interfaces which typically provide support for receiving input from a number of disparate devices that are operated in conjunction to manipulate a given program. A problem arises when applications add in support for explicit devices; which leads to strong coupling between the underlying code and the defined set of devices that they support. In a nutshell, support for new peripherals almost always requires that the original application be recompiled and /or its internal configuration modified to incorporate the given device(s). Portal, an interaction independence framework, seeks to add a layer of abstraction between arbitrary application code and the devices they support; allowing developers to deal in the realm of abstract program actions instead of crafting code to handle a variety of concrete device inputs. This should eliminate the need for custom device-tailored code for each user-wielded peripheral that an application must support and will enable application device support to be managed via configuration changes to the Portal middleware framework, rather than being hard-coded into an application. This thesis will define the conceptual design of the Portal framework while, at the same time, elaborating on the role that web services will play within it; investigate two pervasive service-oriented architecture paradigms, SOAP and REST, in order to gauge their potential effectiveness in meeting Portal â s underlying back-end data transmission requirements; provide implementations for the Portal service-oriented architecture and data model; and, finally, critically evaluate both implementations with an emphasis on their performance with regard to both efficiency and scalability.

Annotation:

Un service Web est un moyen d'offrir des fonctionnalités sur un réseau en utilisant des normes ouvertes pour la description et l'invocation. Les services Web représentent une réalisation importante de l'Architecture Orientée Service (AOS), à l'aide de qui, les applications peuvent être développées rapidement avec un coût bas par couplage faible les services sur un réseau. Cela nécessite la découverte et la composition des ensembles de services interopérables, selon certaines exigences fonctionnelles et non fonctionnelles. Les services Web confrontent de nombreux défis quant à leur découverte et sélection, en raison de plusieurs facteurs tels que: le nombre important de services, le manque de registres publics capables d'offrir des mécanismes efficaces de récupération de service, de leur nature dynamique qui impose divers aspects de QoS tels que la disponibilité, le temps de réponse, etc, et le manque de sémantique dans leurs descriptions d'interface. Dans cette thèse, nous avons deux objectifs principaux. Notre premier objectif est de faciliter la sélection des services Web et d'assurer la continuité du service dans des compositions de services Web. Par conséquent, nous proposons une approche basée sur l'analyse formelle de concepts (AFC) pour classer les services Web dans un premier temps par mots clés, puis par les valeurs de similarité entre leurs opérations. Cette classification est représentée comme un treillis de concepts qui révèle les relations entre les services, ce qui facilite la sélection d'un service nécessaire ainsi que l'identification des potentiels sauvegardes (substitutions en cas de panne). Notre deuxième objectif est de guider l'utilisateur en effectuant une sélection optimisée basée sur des plusieurs critères. Nous définissons un descripteur pour l'utilisateur qui spécifie des exigences fonctionnelles et non fonctionnelles. Dans ce descripteur, les propriétés fonctionnelles sont spécifiées comme un ensemble de mots-clés. Les propriétés non fonctionnelles représentent les niveaux attendus de QoS (bon, mauvais, moyen, ..) ainsi que la composition de services exprimée en tant que liens entre les propriétés fonctionnelles spécifiées. Afin d'atteindre cet objectif, nous proposons une approche basée sur l'analyse relationnelle de concepts (ARC) qui classifie les services Web en treillis de concepts similaires à la AFC, mais enrichis avec les propriétés non-fonctionnelles. Nous proposons également un mécanisme permettant d'interroger le concept de treillis résultant basée sur RCA, selon les exigences spécifiées dans le descripteur. Nous avons validé notre proposition en utilisant des services Web réels extraits de Service-Finder et Seekda (des moteurs de recherche de services Web). Pour l'approche basée sur la AFC, nous avons récupéré un total de 145 services Web que nous avons classés en fonction de leur fonctionnalité. Nous avons montré comment sélectionner efficacement un service offrant les fonctionnalités requises et la manière d'identifier ses sauvegardes. Pour l'approche basée sur RCA, nous avons récupéré 901 services Web que nous avons classés selon leur niveau de QoS et de composabilité. Nous avons vérifié que cette approche permet une sélection efficace des services correspondant aux exigences fonctionnelles et non fonctionnelles spécifiées
A Web service is a way of offering functionality over a network using open standards for description and invocation. Web services represent an important realization of Service-Oriented Architectures (SOA), using which, applications can be developed rapidly with a low cost by loosely coupling services over a network. This necessitates discovering and composing sets of interoperable services, according to some functional and non-functional requirements.Web services face many challenges regarding their discovery and selection, due to several factors like: the fairly large number of services, the lack of public registries capable of offering efficient service retrieval mechanisms, their dynamic nature which imposes various QoS aspects such as availability, response time, etc., and the lack of semantics in their interface descriptions.In this thesis, we have two main objectives. Our first objective is to facilitate Web service selection and assure service continuity in Web service compositions. Therefore, we propose an approach based on Formal Concept Analysis (FCA) to classify Web services first by keywords then by similarity values between their operations. This classification is represented as a concept lattice that reveals the relations between the services, which facilitates the selection of a needed service as well as the identification of its potential backups (substitution in case of failure).Our second objective is to guide the user towards performing an optimized multi-criteria based selection. We define a user requirements descriptor that specifies the needed functional and non-functional properties. Inside this descriptor, functional properties are specified as a set of keywords. Non-functional properties represent the expected QoS levels (good, bad, medium, ..) as well as the composition of services expressed as links between the specified functional properties. In order to meet this objective, we propose an approach based on Relational Concept Analysis (RCA) that classifies Web services into concept lattices similar to FCA, but enriched with the non-functional properties. We also propose a mechanism to query the resulting RCA-based concept lattices, according to the requirements specified in the descriptor.We validated our proposition using real Web services retrieved from Service-Finder and Seekda Web service search engines. For the FCA-based approach, we retrieved a total of 145 Web services that we classified by their functionality. We showed how to select efficiently a service offering the required functionality and how to identify its backups.For the RCA-based approach, we retrieved 901 Web services that we classified by their QoS and composability levels. We verified that the approach allows an efficient selection of services corresponding to the specified functional and non-functional requirements

Tato diplomová práce se zabývá problematikou servisně orientované architektury a služeb, které tvoří její základní stavební prvky. Jejím cílem je vymezení způsobu, jakým lze navrhovat jednotlivé podnikové aktivity jako služby, které jsou založeny na podobném principu a disponují stejnými charakteristikami jako služby, které jsou navrhovány na technologické úrovni SOA. Práce je rozdělena do pěti částí. Smyslem prvních čtyřech je vytvoření určitého teoretického základu, který je následně využit pro účely prakticky orientovaného příkladu, který se zabývá identifikací služeb. První část je věnována vysvětlení podstaty a významu enterprise architektury. Na ní navazuje další část, která ze zabývá architektonickými frameworky a jejímž smyslem je popsání charakteristik frameworku NGOSS (New Generation Operations Systems and Software), který je určen pro poskytovatele telekomunikačních služeb. Nástroje tohoto frameworku, kterými jsou datový model eTOM (enhanced Telecom Operations Map) a datový model SID (Shared Information/Data Model) jsou využívány v již zmiňované závěrečné části. Předposlední část práce je věnována teoretickému pojednání o servisně orientované architektuře a službách. Kapitola obsahuje popis procesu zavádění servisně orientované architektury a dále uvádí charakteristiky, kterými by měli služby disponovat. Závěr práce je věnován názornému příkladu, jak přistupovat k identifikaci služeb. V rámci závěrečné části je jednak navrhován postup, jak služby identifikovat na základě podnikových procesů a jednak jsou zde demonstrovány a hodnoceny možnosti využití obou zmiňovaných nástrojů frameworku NGOSS v rámci tohoto postupu

Many researches have helped to establish correlations between coordination of software development activities and Software Architecture in projects with distributed teams. To better understand how architects are designing this kind of projects we present, in this research, a qualitative study on the influence of Software Architecture in Distributed Software Development (DSD). We collect information from Software Architects involved in DSD projects about the architecture. Information collected has exposed the wide adoption of Service Oriented Architectures (SOA) by companies developing distributed projects, indicating a trend towards to the use of this low coupling architectural style. More detailed data collected by follow-up interviews showed the implementation of practices and SOA design patterns. This practices and patterns were set up in a conceptual framework from which an experiment was conducted to compare the effort in developing DSD projects using the concepts of the framework with effort without using those concepts. The results of this experiment showed that using development practices in SOA can reduce the effort in developing DSD projects based on that architectural style.
Diversas pesquisas têm contribuído para estabelecer a relação entre coordenação de atividades e Arquitetura de Software em projetos com equipes distribuídas. Em um estudo qualitativo preliminar sobre a influência da Arquitetura de Software no Desenvolvimento Distribuído de Software coletou-se informações de Engenheiros de Software de empresas envolvidas em projetos de Desenvolvimento Distribuído de Software. Esse estudo expôs a larga utilização de arquiteturas orientadas a serviço (SOA), indicando uma tendência ao uso desse padrão de arquitetura de baixo acoplamento por empresas que desenvolvem seus projetos de forma distribuída. Estudos posteriores revelaram um conjunto de práticas de desenvolvimento em SOA, utilizadas por essas empresas. Esse conjunto de práticas foi organizado em um framework conceitual a partir do qual se realizou um experimento para comparar o esforço empregado no desenvolvimento de projetos DDS utilizando os conceitos desse framework, com o esforço sem a utilização desses conceitos. Os resultados do experimento mostraram que utilizar as práticas de desenvolvimento em SOA pode reduzir o esforço no desenvolvimento de projetos DDS que utilizam esse estilo arquitetural.

Increasing energy demand will not only aggravate global warming, but also cause fossil fuels shortage in the near future. Solar energy is an infinite green energy resource that can potentially satisfy our energy usage. By utilizing solar energy to drive reactions like water splitting, solar fuels system are able to produce valuable energy resource. Catalysts for water oxidation are the essential component of water splitting cells which have been intensively studied. As a solid state porous crystalline material with synthetic tunability, Metal-organic framework (MOF) is a promising platform for water oxidation catalysis due to its outstanding properties. Herein, we aimed to develop molecular catalysts incorporated MOF for water oxidation and study the reaction mechanism. Chapter 1 introduces the background of water oxidation and previous research on ruthenium nuclear water oxidation catalysts (WOCs). The reaction mechanism of binuclear and mononuclear ruthenium WOCs was briefly summarized. Opportunities for the design and the synthesis of MOF based WOCs were then discussed. Lastly, studies about MOF based WOCs were categorized based on the difference of the WOCs active site location in frameworks. Water oxidation catalyst [Ru(dcbpy)(tpy)OH2]2+ (RuTB) was incorporated into UiO-67 MOF (resulting materials denoted as RuTB-UiO-67) for chemical water oxidation in Chapter 2. Differences of catalytic reaction behavior between homogeneous RuTB and RuTB incorporated in MOF were examined. Based on MOF particle size dependent catalysis reaction experiments, in-MOF reactivity was anticipated to be primarily arose from redox hopping between RuTB active sites in the framework. In Chapter 3, RuTB-UiO-67 MOF thin films grown on conducting FTO substrate (RuTB-UiO-67/FTO) were synthesized to test their catalytic activity of electrochemical water oxidation. Electrochemical behavior of RuTB-UiO-67/FTO was found to be consistent with homogeneous RuTB by various electrochemistry study and in-situ X-ray absorption spectroscopy characterization. Scan-rate-dependent voltammetry study demonstrated the homogeneous distribution of electrochemical active sites throughout the MOF thin film. Diffusion controlled redox hopping was attributed to be the main charge transfer pathway during catalysis. In order to pursue photo-induced water splitting system, we further our study by investigating MOF based photoelectrochemical catalysis in Chapter 4. Photoelectrochemical alcohol oxidation was chosen as the preliminary-stage study towards the more challenging goal, photoelectrochemical water oxidation. Electron transfer processes of the photosensitizer ([Ru(bpy)2(dcbpy)]2+) and the catalyst (RuTB) doped UiO-67 MOF were investigated with transient absorption spectroscopy analysis. Finally, the role of redox hopping in electrocatalysis by MOF was reviewed in Chapter 5. Pathways of charge transfer in electroactive MOF were first summarized. Redox hopping in MOF was then compared with previous studies on redox active polymer thin films. Lastly, factors that will affect the rate of redox hopping of MOF electrocatalyst were discussed.

The demand for systems i·ntegration has become more and more significant in higher education as institutions want systems that provide coherent information with data that is up to date and not redundant and can seamlessly support the end user experience. Institutions have become more reliant on information systems to support both administrative functions and those involved in teaching, learning and research, but because each department supports a diverse array of computing platforms and applications, it becomes very difficult to integrate these systems. SOA is classified as an innovative approach to integrating existing systems involving the use of independent services that can be accessed without knowledge of the underlying platform implementation. Unfortunately, the SOA initiative will not be success if it is not understood and used correctly by various applications and systems throughout the organisation. SOA introduces complexity and challenges in systems integration, acceptance, governance, data, development planning, security and external opportunities. If an organisation does not embrace or enable change in each of these areas, it is not ready for the adoption of SOA. This research investigates the systems integration challenge in selected South African universities and explores factors for SOA adoption. The framework for the adoption of SOA comprises seven factors, of which Systems Integration is the most significant and represents an efficient starting point for institutions considering SOA adoption. Acceptance, Governance, Data, Development Planning, Security and External Opportunities are other factors of SOA adoption that require careful and thorough consideration before an institution can successfully adopt SOA. The results of this research emphasise the importance of being able to embrace change and innovation and modify strategies in order to reflect the constant changes required for the adoption of SOA.

We are currently witnessing a constant increase in the presence of renewable energies in the urban environment, especially solar energy. This inevitably causes a visual impact that is not always socially accepted. The main theme of this thesis is the aesthetic perception of solar installations integrated into the city and establishes an elementary conceptual framework that includes several relevant lines of research. A first line analyses the most influential objective factors in the aesthetic impact produced by these facilities. The second line delves into the subjective perception experienced by the individual. And finally, within the European geographical framework, it studies the degree of involvement of entities that carry out projects to implement renewable energies in the city, in the aesthetic impact that these projects generate. The results of the research have repercussions on society and on the processes of implementing renewable energies.

Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. It also enables output firmness, providing stability to the power block and to the grid. Thus, despite the additional investment, storage can enhance the performance and economic viability of the plants. However, the levelized cost of electricity of these plants yet remains higher than for other technologies, so projects today are only viable through the provision of incentives or technology-specific competitive bid tenders. It is the variability of the solar resource, the myriad roles that storage can assume, and the complexity of enhancing the synergies between the solar field, the storage and the power block, what makes the development of adequate policy instruments, design and operation of these plants a challenging process. In this thesis a comprehensive methodology for the pre-design and analysis of concentrating solar power plants is presented. The methodology is based on a techno-economic modeling approach that allows identifying optimum trade-off curves between technical, environmental, and financial performance indicators. A number of contemporary plant layouts and novel storage and hybridization concepts are assessed to identify optimum plant configurations, in terms of component size and storage dispatch strategies. Conclusions highlight the relevance between the sizing of key plant components, the operation strategy and the boundaries set by the location. The interrelation between critical performance indicators, and their use as decisive parameters, is also discussed. Results are used as a basis to provide recommendations aimed to support the decision making process of key actors along the project development value chain of the plants. This research work and conclusions are primarily meant to set a stepping stone in the research of concentrating solar power plant design and optimization, but also to support the research towards understanding the value of storage in concentrating solar power plants and in the grid.
Koncentrerad solkraft erbjuder möjligheten att integrera kostnadseffektiv termisk energilagring och därmed behovsstyrd kraftkontroll. Detta är en viktig fördel jämfört med andra förnybara energiteknologier. Lagringsintegration tillåter solkraftsanläggningar att öka sin lastfaktor och skifta produktion till tider med största efterfrågan. Vidare möjliggör lagring fast elproduktion vilket leder till förbättrad nät- och kraftturbinstabilitet. Därför kan termisk lagring öka anläggningsprestanda och ekonomiskt värde trots ökande initiala kapitalkostnader. I termer av specifik elproduktionskostnad (LCOE) ligger koncentrerade solkraftsanläggningar med lagring fortfarande högre än andra kraftteknologier och anläggningsprojekt blir endast lönsamma genom subventionsmodeller eller teknologispecifika konkurrensutsatta anbudsförfaranden. Att hitta adekvata policylösningar och optimala design och operationsstrategier är en utmanande process eftersom det gäller att hitta rätt balans mellan variabel solinstrålning, lagring av energi och tid för produktion genom optimal design och operation av solmottagarfält, kraftblock och lagringskapacitet. I denna avhandling presenteras en omfattande metodik för pre-design och analys av koncentrerande solkraftverk. Metodiken baseras på en tekno-ekonomisk modelleringsansats som möjliggör identifiering av optimala avvägningssamband för tekniska, ekonomiska och miljöprestanda indikatorer. Metodiken tillämpas på ett antal moderna anläggningslayouter och lagrings- och hybridiseringskoncept för att identifiera optimal kraftanläggningsdesign i termer av komponentprestanda och lagringsanvändningsstrategier. I slutsatsen poängteras relevansen av att hitta rätt storlek på nyckelkomponenter i relation till lagringsstrategi och randvillkoren som ges av konstruktionsläget för optimal ekonomisk och miljömässig prestanda. Resultaten används för att formulera rekommendationer till nyckelaktörer i beslutsprocessen genom hela kraftanläggningens värdekedja från politisk beslutsfattare till anläggningsingenjör. Forskningen och slutsatserna i detta arbete skall i första hand ta ett steg framåt för optimering och design av solkraftsanläggningar men även tillhandahålla en metodik för utvärdering av lagringslösningar och dess specifika värde för solkraftsanläggningar och elnätet.

A range of inorganic materials, with structures based on transition metal centred polyhedra linked through simple or polyatomic anions, has been synthesised and fully characterised. These materials were prepared using a variety of synthetic methods, including the direct high temperature, solid state reactions, and hydrothermal techniques in fluoride rich media. The materials produced were structurally characterised by powder (PXD) and single crystal (SXD) X-ray diffraction techniques with further analysis via infrared and UV/visible/near-infrared spectroscopies, thermogravimetric analysis and scanning electron microscopy. Copper (II) phosphates and related materials have potential applications derived from their near-infrared (NIR) radiation absorbing properties. A range of complex copper phosphate phases in the Cu-P-O or A-Cu-P-O systems, where A is a Group 1 or 2 element, has been synthesised and characterised. The intensity and positions of absorptions in the NIR region found for these materials and derived from d-d transitions on copper, are dependent upon the copper ion coordination geometry and the ligand field produced by the surrounding anions. K2CuP2O7 and the phases A3Cu3(PO4)3 (A = Sr, Ca) were all found to absorb strongly in the NIR region. The NIR absorbance spectrum could be modified further by introducing fluoride into the Cu(II) ligand environment and Cu2PO4F was shown to have a very strong, broad NIR absorption spectrum.

With the launch of NASA's Solar Dynamics Observatory mission, a whole new age of high-quality solar image analysis was started. With the generation of over 1.5 Terabytes of solar images, per day, that are ten times higher resolution than high-definition television, the task of analyzing them by scientists by hand is simply impossible. The storage of all these images becomes a second problem of importance due to the fact that there is only one full copy of this repository in the world, therefore an alternate and compressed representation of these images is of vital importance. Current automated image processing approaches in solar physics are entirely dedicated to analyze individual types of solar phenomena and do not allow researchers to conveniently query the whole Solar Dynamics Observatory repository for similar images of their interests. We developed a Content-based Image Retrieval system that can automatically analyze and retrieve multiple different types of solar phenomena, this will fundamentally change the way researchers look for solar images in a similar way as Google changed the way people searched the internet. During the development of our system, we created a framework that would allow researchers to tweak and develop their own content-based image retrieval systems for different domain-specific applications with great ease and a deeper understanding of the representation of domain-specific image data. This framework incorporates many different aspects of image processing and information retrieval such as: image parameter extraction for reduced representation of solar images, image parameter evaluation for validation of image parameters used, evaluation of multiple dissimilarity measures for more accurate data analysis, analyses of dimensionality reduction methods to help reduce storage and processing costs, and indexing and retrieval algorithms for faster and more efficient search. The capabilities of this framework have never been available together as an open source and comprehensive software package. With these unique capabilities, we achieved a higher level of knowledge of our solar data and validated each of our steps into the creation of our solar content-based image retrieval system with an exhaustive evaluation. The contributions of our framework will allow researchers to tweak and develop new content-based image retrieval systems for other domains (e.g astronomy, medical field) and will allow the migration of astrophysics research from the individual analysis of solar phenomenon into larger-scale data analyses.

L'adaptation est aujourd'hui devenue un enjeu majeur en Génie Logiciel. Les ingénieurs sont en effet régulièrement confrontés à des demandes d'évolution qui peuvent prendre de nombreuses formes : mises à jour, nouvelles versions, besoins en nouvelles fonctionnalités, etc. Cette tendance est accrue par l'émergence de nouveaux domaines tels que l'informatique ubiquitaire ou le cloud computing qui exigent des changements dynamiques dans des environnements en constante évolution. Ainsi, dans ces domaines, les ressources sont souvent élastiques, volatiles et hétérogènes. Cette thèse s'intéresse en particulier à la conception et à l'exécution d'applications distribuées composées d'entités hétérogènes et qui nécessitent d'être adaptées durant l'exécution. Notre approche s'appuie sur les modèles à composant orientés service et sur les styles d'architectures SOA et REST. Nous proposons un framework, nommé RoSe, qui permet l'import de ressources distantes dans un framework à composant orienté service et l'export de service locaux. RoSe permet aux développeurs et aux administrateurs de gérer la distribution des applications de manière totalement indépendante et dynamique grâce à un langage de configuration et d'une API dite fluent. Le framework lui-même est modulaire et flexible et supporte l'ajout et le retrait de composants durant l'exécution. L'implantation de RoSe est hébergée au sein du projet OW2 Chameleon et est aujourd'hui utilisée dans plusieurs projets industriels et académiques.

Recent developments in embedded systems give robots access to the Internet and make them more flexible and capable of performing more complex applications. However, these robots are still limited in terms of size, CPU power, storage resources and memory. Consequently, these robots have only been manufactured for certain specific applications and cannot be re-used for other applications. This presents us with a challenge to design a software framework - Robot Colony. The Robot Colony enables robots to be suitable for a wide range of applications, not originally received from manufacturers, to achieve greater functionality, flexibility and utility. This research outlines the architecture and functionality of the Robot Colony to support the collaboration between devices in the P2P community and also analyse the JXTA platform, which was the framework originally proposed. Lastly we present a customized P2P architecture that specifically addresses the interaction betweensoftware components across the network. We further discuss the following technologies applied in theframework: * XML-based Directory Service Provider * HTTP-based publish/describe control commands * Remote Process Invoke To fully complete the project, a thorough evaluation of the framework based on either the JXTAplatform or the customized P2P channel has been conducted. This evaluation provides basic statistics data for the proposed framework design and implementation. Further more, we have presented a realtime Demo at the Smart Device lab of the Queensland University of Technology.

The main topic of this thesis is the application of best practice methodology to the development of services in public administration and e-Government. The work focuses on interoperable services that can be integrated across departments of public administration or businesses in the private sector. In section 2 we describe the various aspects influencing the development of interoperable services in public administration using the European Interoperability Framework (EIF) as a basis for classifying interoperability dimensions. Section 3 evaluates current state of services in public administration focusing on information interoperability that addresses syntactic, structural and semantic heterogeneity. We have found that Services of Public Administration Portal (PVS) suffer from high levels of structural and syntactic heterogeneity, and we discuss possible ways to standardize service interfaces in public administration in order to improve interoperability. Creation of standardized library of services has been proposed as a possible way forward. In section 4 of the thesis we propose a methodological framework for the development of e-Government services using the best practices methods identified in the private sector domain. The main emphasis is placed on library services and its role in the lifecycle of services. Stages of lifecycle of services are decomposed into sub-phases so that they match phases in the MMDIS methodology.

Renewable energy resources (RES) are becoming more popular for electricity generation due to their easy installation, flexibility, low cost, environmental compatibility, etc. However, their fluctuating nature is a major drawback, which decreases the power quality and makes them less trusty in the power system. To mitigate this problem, battery energy storage (BES) has been widely used with renewable energy sources. Because batteries are designed to handle “steady fluctuations” of power, the “sudden and peak” fluctuating power levels of renewable energy sources may cause shorter life spans for them, which may cause dramatic economic loss or negatively impact the power quality. Also, even though batteries have been used as a backup for RES, high power quality cannot be guaranteed when there is a rapid and peak fluctuations on source/load.

Climate change is no longer a problem of the future. Climate change is global, rapid, and intensifying. A reality. The latest Intergovernmental Panel on Climate Change (IPCC) report highlights the Anthropocene is behind the unprecedent rising temperatures, leading to extreme weather events such as heatwaves, droughts, heavy precipitation, or tropical cyclones. Climate action must be taken. The energy transition plays a fundamental role when considering the wellbeing of the planet. However, renewable energy finance has always been a challenge. To date, the energy transition has been regrettably underfunded. In 2018, the global energy system was below 50 % of the investment required to keep global warming below 1.5 °C and avert the worst consequences of the climate crisis[4]. This staggering statistic clearly shows that financial investment needs to either be redirected to the energy transition, or new financing channels must be open. Seeds Renewables, a California-based startup, has come up with a solution which has the potential to cover a portion of the energy financing deficit by enabling people to invest in renewable energy projects from as little as their spare change. Before allowing their users to invest, Seeds carries out the due diligence of the projects to determine the feasibility of the installation. It is identified that there is a current lack of concise and public literature regarding the process required to determine the technical feasibility and economic profitability of projects. This thesis serves as a guide for lenders, such as Seeds Renewables, who aim to conduct techno-economic assessments on solar photovoltaic installations. This core objectiveis complemented by qualitative checklists for project development and legal due diligence to provide a comprehensive overview of the factors which surround the techno-economic analysis of solar arrays. Furthermore, the optimal software available in the market to carry out an analysis of solarphotovoltaic installation is identified. The thesis covers the background research conducted on solar photovoltaic systems, acompilation of project due diligence best practices, insights on renewable energy project finance anda literature review on photovoltaic analysis software tools which leads to the selection of two softwares. PVsol and PVsyst are compared by means of a Multi-Criteria Analysis. A case study is conducted on a 63.3 kW solar photovoltaic array installed in 2016 to test the selected softwares. The array is located on the roof of Rinaldi Tile in Pajaro, California, United States of America. The array is replicated using PVsol and PVsyst. Consequently, the simulation predictions are compared to the real production data extracted from the system’s inverter. The performance ratio from the real data, PVsol and PVsyst are 82.4 %, 85.9 %, 80.51 % respectively. The real quantity of power produced over a 5-year period of study is average of 82.24 MWh whilethe simulations by PVsol and PVsyst predict 93.49 MWh and 81.30 MWh respectively. The discrepancy between the real data and software results is due to limitations of both tools. After evaluating the accuracy of the solar PV simulation tools, the Multi-Criteria Analysis rates PVsyst as the more desirable tool. Using this study, engineers or investors will have a clear framework to follow when carrying out the project due diligence on a solar photovoltaic installation and a rating of the available softwaresto assess the viability of the solar arrays.
Klimatförändringarna är inte längre ett framtidsproblem. Klimatförändringarna är globala, snabba och intensifierande. En verklighet. Den senaste Intergovernmental Panel on Climate Change (IPCC) rapporten visar att Antropocen ligger bakom de aldrig tidigare skådade temperaturerna, vilket leder till extrema väderhändelser som värmeböljor, torka, kraftig nederbörd eller tropiska cykloner. Klimatåtgärder måste vidtas. Energiomställningen spelar en grundläggande roll när man överväger planetens välbefinnande. Finansiering av förnybar energi har dock alltid varit en utmaning. Hittills har energiomställningen tyvärr varit underfinansierad. År 2018 låg det globala energisystemet under 50% av investeringarna som krävs för att hålla den globala uppvärmningen under 1,5 ° C och avvärja de värstakonsekvenserna av klimatkrisen [4]. Denna häpnadsväckande statistik visar tydligt att finansiella investeringar antingen måste omdirigeras till energiomställningen eller att nya finansieringskanaler måste vara öppna. Seeds Renewables, en Kalifornienbaserad startup, har kommit fram till en lösning som har potential att täcka en del av energifinansieringsunderskottet genom att göra det möjligt för människor att investera i förnybara energiprojekt från så lite som deras växel. Innan de tillåter sina användare att investera, utför Seeds projektets due diligence -analys för att avgöra genomförbarheten av installationen. Det identifieras att det för närvarande saknas kortfattad och offentlig litteratur om processen som krävs för att bestämma projektens tekniska genomförbarhet och ekonomiska lönsamhet. Denna avhandling fungerar som en vägledning förlångivare, till exempel Seeds Renewables, som syftar till att göra tekno-ekonomiska bedömningar avsolcellsanläggningar. Detta kärnmål kompletteras med kvalitativa checklistor för projektutvecklingoch juridisk due diligence för att ge en övergripande överblick över de faktorer som omger den tekno-ekonomiska analysen av solsystem. Dessutom identifieras den optimala programvara som finns tillgänglig på marknaden för att utföra en analys av solcellsinstallation. Avhandlingen omfattar bakgrundsforskning på solcellssystem, en sammanställning av bästa praxis för aktsamhet, insikter om projektfinansiering för förnybar energi och en litteraturgenomgång om programvara för fotovoltaiska analyser som leder till val av två programvaror. PVsol och PVsyst jämförs med hjälp av en multikriterieanalys. En fallstudie genomförs på en solcellsanläggning på 63,3 kW installerad 2016 för att testa de utvalda programvarorna. Arrayen ligger på taket av Rinaldi Tile i Pajaro, Kalifornien, USA. Arrayen replikeras med PVsol och PVsyst. Följaktligen jämförs simuleringsprognoserna med de verkliga produktionsdata som extraherats från systemets inverter. Prestandakvoten från de verkliga uppgifterna, PVsol och PVsyst är 82.4 %, 85,9% respektive 80,51%. Den verkliga mängden kraft som produceras under en 5-års studieperiod är i genomsnitt 82,24 MWh medan simuleringarna av PVsol och PVsyst förutsäger 93,49 MWh respektive 81,30 MWh. Skillnaden mellan de verkliga data- och programvareresultaten beror på begränsningar för båda verktygen. Efter att ha utvärderat noggrannheten i solcells-PV-simuleringsverktygen med multikriterieanalysen bedöms Multi-Criteria Analysis PVsyst som det mer önskvärda verktyget. Med hjälp av denna studie kommer ingenjörer eller investerare att ha en tydlig ram att följa när projektet genomförs due diligence på en solcellsanläggning och en bedömning av de tillgängliga programvarorna för att bedöma matrisernas livskraft.

Annotation:

Next Generation Networks (NGNs) aim to provide a unified network infrastructure to offer multimedia data and telecommunication services through IP convergence. NGNs utilize multiple broadband, QoS-enabled transport technologies, creating a converged packet-switched network infrastructure, where service-related functions are separated from the transport functions. This requires significant changes in the way how networks are managed to handle the complexity and heterogeneity of NGNs. This thesis proposes a Service Oriented Architecture (SOA) based management framework that integrates heterogeneous management systems in a loose coupling manner. The key benefit of the proposed management architecture is the reduction of the complexity through service and data integration. A network management middleware layer that merges low level management functionality with higher level management operations to resolve the problem of heterogeneity was proposed. A prototype was implemented using Web Services and a testbed was developed using trouble ticket systems as the management application to demonstrate the functionality of the proposed framework. Test results show the correcting functioning of the system. It also concludes that the proposed framework fulfils the principles behind the SOA philosophy.

This dissertation document deals with the development of a project, over a span of more than two years, carried out within the scope of the Arrowhead Framework and which bears my personal contribution in several sections. The final part of the project took place during a visiting period at the university of Luleå. The Arrowhead Project is an European project, belonging to the ARTEMIS association, which aims to foster new technologies and unify the access to them into an unique framework. Such technologies include the Internet of Things phe- nomenon, Smart Houses, Electrical Mobility and renewable energy production. An application is considered compliant with such framework when it respects the Service Oriented Architecture paradigm and it is able to interact with a set of defined components called Arrowhead Core Services. My personal contribution to this project is given by the development of several user-friendly API, published in the project's main repository, and the integration of a legacy system within the Arrowhead Framework. The implementation of this legacy system was initiated by me in 2012 and, after many improvements carried out by several developers in UniBO, it has been again significantly modified this year in order to achieve compatibility. The system consists of a simulation of an urban scenario where a certain amount of electrical vehicles are traveling along their specified routes. The vehicles are con-suming their battery and, thus, need to recharge at the charging stations. The electrical vehicles need to use a reservation mechanism to be able to recharge and avoid waiting lines, due to the long recharge process. The integration with the above mentioned framework consists in the publication of the services that the system provides to the end users through the instantiation of several Arrowhead Service Producers, together with a demo Arrowhead- compliant client application able to consume such services.

The purpose of this dissertation was to develop, test, and evaluate a framework to assist investors in photovoltaic (PV) power plants in dust-prone arid regions make informed decisions regarding selection among PV panel cleaning alternatives. Soiling of PV panels is a problem in dust-prone arid regions such as the Arabian Gulf where daily dust deposition and frequent dust storms coupled with lack of rainfall can compromise PV panel energy output. There are several alternatives to clean the PV panels. However, not much research has been done to determine the most favorable means to do so or how often it is feasible to perform the cleanup. Furthermore, the decision maker/investor might face difficulty in selecting among several cleaning alternatives given the competing requirements that must be considered in the selection process. Therefore, in this research a framework was developed to assist investors in PV power plants determine: (1) how often it is economically feasible to clean the PV panels using different cleaning alternatives, (2) what impacts those cleanups have on the overarching factors considered during the selection process, and (3) what the most favorable cleaning alternative is in light of several competing requirements.

A hypothetical 1 MW PV plant located in Riyadh, Saudi Arabia, was used to test the developed framework which was accomplished by: (1) estimating the PV plant's lifetime energy yield using a PV performance simulation program, (2) researching and estimating the effects of daily dust deposition and dust storms on the panels' output, (3) surveying and collecting PV panel cleaning alternative cost and performance data, (4) developing a spreadsheet program to simulate PV plant lifetime performance under different scenarios using input data from the previous 3 steps, (5) using a multi criteria decision method (MCDM) to select among cleaning alternatives in light of competing criteria, (6) performing a sensitivity check on the criteria weights in the MCDM to check the robustness of the results.

Research results indicated that although PV panel cleaning can consume large amounts of water and result in release of harmful emissions to the environment, the benefits of such cleaning can be worth it. The results also indicated that for each given scenario, an optimum cleaning threshold can be determined. It was also determined that initiating a cleanup when the soiling reaches a certain threshold is a preferable approach to cleaning using a fixed schedule. In addition, One-on-one interviews with subject matter experts to elicit their opinion resulted in determination of the selection criteria and priorities used in the MCDM which consequently resulted in selection of a preferred alternative. The results of the MCDM showed that opinion and preferences can vary drastically among different stakeholders and that, for each particular scenario, the set of relevant criteria and their priorities will depend on the stakeholders involved and their influence on the selection decision. Subject matter expert evaluation of the developed framework on whether it can improve selection among PV panel cleaning alternatives was accomplished via a questionnaire in which the experts rated the degree of their agreement or disagreement on a Likert scale. Average results indicated agreement that the study can improve selection among PV panel cleaning alternatives.

A Arquitetura Orientada a Serviços (SOA) oferece um modelo arquitetônico que visa aprimorar a eficiência, a agilidade e a produtividade de empresas. Nesse modelo, os serviços são os principais meios para que os objetivos estratégicos sejam atingidos. Entretanto, o desenvolvimento de sistemas que utilizam este estilo de arquitetura tem exigido novas estratégias dentro da Engenharia de Software (ES), principalmente no tocante à disciplina de Engenharia de Requisitos (ER). Por outro lado, observa-se que as abordagens da Engenharia de Requisitos Orientada a Objetivos (GORE) têm ganhado notoriedade nos últimos anos. De fato, as abordagens orientadas a objetivos apresentam mecanismos que não são ofertados pela ER tradicional, como por exemplos capturar os objetivos dos stakeholders e as características do sistema em um mesmo modelo. Assim, é possível usar esse modelo para analisar e identificar se o sistema proposto atende aos objetivos dos stakeholders. Esse é um importante tipo de análise no contexto organizacional. No entanto, a literatura não apresenta uma forma sistemática para identificar serviços em modelos de requisitos orientados a objetivos. Além disso, há uma lacuna a ser preenchida na transição dos requisitos (espaço do problema) para a arquitetura equivalente (espaço da solução), no contexto da SOA. Dessa forma, este trabalho apresenta uma abordagem sistemática para a identificação de serviços em modelos GORE descritos em i* e a posterior obtenção da arquitetura SOA descrita em SoaML. A abordagem foi validada através de um estudo empírico com usuários reais.

Annotation:

Service-Oriented Architecture (SOA) is becoming the mainstream for providing efficient and agile business solutions that can keep up with changes demanded by the business world. The task of identifying candidate services is one of the main activities in developing software service-oriented models. The current service identification approaches exhibit some limitations, where they are either too complex to be adopted, too simple to satisfy all SOA principles, or are theoretical approaches that are far from automation. On the other side, ontologies have been introduced in a number of phases in the SOA development lifecycle, mainly in the design and implementation phases. This research is concerned with introducing an ontology-based framework to semantically generate services from business process architectures (BPA) and using a simple service identification approach that is based on the BP A for an organisation. In this research, a novel architectural framework has been introduced that is generic, extensible, BPA-driven, ontology-based and domain independent, but uses a simple and automatic service identification approach that adheres to SOA principles. We named this framework BPAOntoSOA, and its activities are structured into two main layers. The first layer is concerned with generating a business process architecture ontology, namely the BPAOnt ontology, for a particular organisation given the Riva-based business process architecture of that organisation and the set of associated business process models. The second layer is concerned with identifying the software services using the generated BP AOnt ontology for that organisation. In order to realise this framework, we developed the abstract BP AOnt ontology to provide a conceptual representation of Riva BP A elements and the associated BPM elements. We have also proposed a novel service identification approach based on the Riva BPA and utilised its simplicity (as being systematic in identifying and modelling a BPA) to identify services in a simple and straightforward manner while satisfying SOA principles. The BP AOntoSOA framework, the BP AOnt ontology and the proposed service identification approach have been evaluated using the Jordan's Cancer Care and Registration (CCR) processes case study in an attempt to assess the correctness of the service identification approach as well as the framework behaviour in general. This has revealed that: (1) the BP AOnt ontology contributes remarkably not only as a major component in the BP AOntoSOA framework, but also as a source of business knowledge describing the process architecture and associated business process models of an organisation to be extracted and reused, (2) the service identification approach is simple, automatic and conforms to SOAprinciples, (3) the introduction of the concept of RP A clusters to the Riva method in order group related architectural elements forming the basis for identifying services and, (4) a further suggested modification to the Riva method in order to provide better conformance to SOA principles and hence better alignment between BP As and the service oriented model of computing. In Conclusion, this research has contributed to align business process architecture and the service oriented model of computing through the newly introduced BPAOntoSOA framework. xix

The objective of present thesis is to prepare and evaluate photocatalyst for hydrogen generation from water methanol mixture using solar light. This general objective has been accomplished by applying different methodology in material preparation as well as exploring the photocatalytic activity of novel semiconductors. In this way after a general introduction to the feed showing the relevance of solar fuels and in particular hydrogen generation, the focus of chapter 3 is, on the other and, to optimize the nature of the cocatalyst based on noble metals. In this way AuPt alloy nanoparticles with different composition will be deposited on p25 and they activity correlated with the irradiation wavelength and nature of the alloy. In chapter 4 and 5 we evaluate the photocatalytic activity of materials derived from titanate nanotubes either by hydrogen annealing ad various temperature (chapter 4) or by forming heterojunction with a combination of titania nanoparticles (chapter 5). The two final chapter of this thesis report the semiconductor behaviour and the photocatalytic activity of framework phosphate either mixed valence titanium III/IV (chapter 6) or iron (chapter 7) doped with various metal. The overall results achieved show that is possible to increase the photocatalytic activity of titanium-based materials by apply concept like control of morphology, amorphization of surface of particles, formation of heterojunction and control of the cocatalyst. We have also shows behind oxide, framework phosphate can also be valuable as photocatalysts.

Abstract CROSS-IDEOLOGICAL SOLAR POWER COALITIONS IN THE AMERICAN SOUTH: AN ADVOCACY COALITION APPROACH By Brian T. Toibin, Ph.D. A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Public Policy and Administration at Virginia Commonwealth University. Virginia Commonwealth University, 2018. Major Director: Dr. Damian Pitt Associate Professor of Urban and Regional Studies and Planning L. Douglas Wilder School of Government and Public Affairs The purpose of this study was to explore two particular cross-ideological coalitions that have formed in order to promote pro-solar power policies in Georgia and Florida through the lens of the Advocacy Coalition Framework. The membership of the coalitions include individuals and organizations from opposite sides of the current prevailing ideological spectrum which united to support pro-solar policies for reasons that are consistent with their ideological worldview. The coalition in Georgia is known as the Green Tea Coalition and the coalition in Florida is known as Floridians for Solar Choice. This qualitative study was guided by the following questions: 1) Why did supporters of solar power organize themselves into the particular coalition structures represented by Georgia’s Green Tea Coalition and the Floridians for Solar Choice Coalition?; 2) How have Georgia’s Green Tea Coalition and the Floridians for Solar Choice Coalition successfully managed their policy coalitions?; 3) How effective are these coalitions perceived to be by public policy players outside the coalitions?; 4) Do the Green Tea Coalition and the Floridians for Solar Choice Coalition represent an Advocacy Coalition approach? Engaging these questions through the effective theoretical lens of the Advocacy Coalition Framework revealed a compelling example of cross-ideological cooperation within an increasingly divided political culture. Significant lessons concerning the formation and successful operation of coalitions were learned. The importance of strategic alliances, public belief systems, policy messaging, electorate education, policy learning, and careful political positioning are a few of the factors that enabled these coalitions to find success. The political success of these coalitions significantly advanced the role that solar power will be allowed to play in the future energy portfolio of these two influential states in the American South and across the country. While the positive results for the future of solar power engineered by the coalitions are impressive, perhaps the most important lessons revealed by the study concern the potential for progress and cooperation on other complex issues. A portfolio of difficult issues awaits action by persons of good faith willing to find a cooperative path on which to move forward. Coalitions will be required to address many of these difficult problems. The lessons and example provided by these two cross-ideological coalitions may help others produce a their own blueprint to encourage cross-ideological cooperation. This cooperation will be required if progress is to be made for the well being of current and future generations.

The rising concerns of climate change and global warming have made the current practices of industrial energy generation and consumption highly unsustainable. There is a growing awareness of the importance of renewable energy use in addressing climate change and establishing sustainable development. One of the renewable sources which have gained popularity over time is solar energy. Among the various solar technologies, one potential segment is solar thermal technology which involves solar thermal collectors. This technology mainly concentrates on providing industrial process heat across a wide range of temperature, and it's classified within the industry of Solar Heat for Industrial Process (SHIP). Though the SHIP technologies show strong technical feasibility, only few industries employ solar heat and there is a decreasing trend of adoption. Hence, this research aims to understand the reasons for decreasing adoption by studying what and how are the factors affecting the adoption of solar thermal technology. This is done by performing a qualitative study across two industrial sectors food and chemical in the region of Middle East and North Africa (MENA). The obtained data by conducting semi-structured interviews are analysed using the Technological-Organization-Environment (TOE) theoretical framework. The results from the study show that there are 9 important factors affecting the adoption of solar thermal technology that are categorized into technological factors (reliability, flexibility, financial attractiveness, and competitive alternatives), organizational factors (management support and resources) and environmental factors (regulatory environment, technology support provider and competitive pressure). Apart from the technological factors of lack of reliability and financial attractiveness, the organizational factors of lack of resources and the environmental factor of low incentives in MENA region, the aspect of cheap competitive alternatives especially in the MENA region, is causing the decrease in adoption within the food and chemical industry.

Since the early 2000s, Service Oriented Architectures (SOAs) have played a key role in the development of complex applications within a virtual organization (VO) context. Grids and workflows have emerged as vital technologies for addressing the (SOA) paradigm. Given the variety of Grid middleware, scientific workflow systems and Grid workflows available, bringing the two technologies together in a flexible, reusable and generalized way has been largely overlooked, particularly from a scientific end user perspective. The lack of domain focus in this area has led to a slow uptake of Grid technologies. This thesis aims to design a framework for Grid-enabling workflows, which identifies the essential technological components, how these components fit together in layered architecture and the interactions between them. To produce such a framework, this thesis first investigates the definition of a Grid-workflow architecture and mapping Grid functionality to workflow nodes, focusing on striking a balance between performance, usability and the Grid functionality supported. Next, it presents an examination of framework extensions for supporting various forms of Grid heterogeneity, essential for ii VO based collaboration. Given the complex nature of Grid technologies, the work presented here investigates abstracting Grid based workflows through high-level definitions and resolution using semantic technologies. Finally, this thesis presents a way to resolves abstract Grid workflows using semantic technologies and intelligent, autonomous agents. The frameworks presented in this thesis are tested and evaluated within the context of domain-based case studies defined in the SIMDAT, BRIDGE and ARGUGRID EU funded research projects.

It is not easy to apply XML in e-commerce development for achieving interoperability in heterogeneous environments. One of the reasons is a multitude of XML-based Frameworks for Internet Commerce (XFIC), or industrial standards. This thesis surveys 15 frameworks, i.e., ebXML, eCo Framework, UDDI, SOAP, BizTalk, cXML, ICE, Open Applications Group, RosettaNet, Wf-XML, OFX, VoiceXML, RDF, WSDL and xCBL.

This thesis provides three models to systematically understand how the 15 frameworks meet the requirements of e-commerce. A hierarchical model is presented to show the purpose and focus of various XFIC initiatives. A relationship model is given to show the cooperative and competitive relationships between XFIC. A chronological model is provided to look at the development of XFIC. In addition, the thesis offers guidelines for how to apply XFIC in an e-commerce development.

We have also implemented a B2B e-procurement system. That not only demonstrates the feasibility of opensource or freeware, but also validates the complementary roles of XML and Java: XML is for describing contents and Java is for automating XML documents (session handling). Auction-based dynamic pricing is also realized as a feature of interest. Moreover, the implementation shows the suitability of e-procurement for educational purposes in e-commerce development.

Annotation:

This thesis proposes a collaboration framework for the Web of Things based on the concepts of Service-oriented Architecture and integrated with semantic web technologies to offer new possibilities in terms of efficient asset management during operations requiring multi-actor collaboration. The motivation for the project comes from the rise in disasters where effective cross-organisation collaboration can increase the efficiency of critical information dissemination. Organisational boundaries of participants as well as their IT capability and trust issues hinders the deployment of a multi-party collaboration framework, thereby preventing timely dissemination of critical data. In order to tackle some of these issues, this thesis proposes a new collaboration framework consisting of a resource-based data model, resource-oriented access control mechanism and semantic technologies utilising the Semantic Sensor Network Ontology that can be used simultaneously by multiple actors without impacting each other’s networks and thus increase the efficiency of disaster management and relief operations. The generic design of the framework enables future extensions, thus enabling its exploitation across many application domains. The performance of the framework is evaluated in two areas: the capability of the access control mechanism to scale with increasing number of devices, and the capability of the semantic annotation process to increase in efficiency as more information is provided. The results demonstrate that the proposed framework is fit for purpose.
