Full textAbstract:
In today’s practical reality there are many different tools being used in their respective phases of thesystem development lifecycle. Every tool employs its own underlying metamodel and these metamodelstend to vary greatly in size and complexity, making them difficult to integrate. One solution to overcomethis problem is to build a tool integration framework that is based on a single, shared metamodel.The iFEST project aims to specify and develop such a tool integration framework for tools used in thedevelopment of heterogeneous and multi-core embedded systems. This framework is known as the iFESTTool Integration Framework or iFEST IF.The iFEST IF uses Web services based on the Open Services for Lifecycle Collaboration (OSLC)standards and specifications to make the tools within the tool chain communicate with each other. Tovalidate the framework, an industrial case study called ‘Wind Turbine’, using several embedded systemstools, has been carried out. Tools used to design, implement and test a controller for a wind turbine havebeen integrated in a prototype tool chain. To expose tools’ internal data through Web services, a tooladaptor is needed. This work reports on the development of such a tool adaptor for the RequirementsManagement module of HP Application Lifecycle Management (ALM), one of the tools used in the WindTurbine industrial case study. A generalization of the challenges faced while developing the tool adaptoris made. These challenges indicate that, despite having a tool integration framework, tool integration canstill be a difficult task with many obstacles to overcome. Especially when tools are not developed with tool integration in mind from the start.Idag existerar det en mängd olika verktyg som kan appliceras i respektive fas isystemutvecklings livscykel. Varje verktyg använder sin egna underliggande metamodell. Dessametamodeller kan variera avsevärt i både storlek och komplexitet, vilket gör dem svåra attintegrera. En lösning på detta problem är att bygga ett ramverk för verktygsintegration sombaseras på en enda, gemensam metamodell.iFEST-projektets mål är att specificera och utveckla ett ramverk för verktygsintegration förverktyg som används i utvecklingen av heterogena och multi-core inbyggda system. Dettaramverk benämns iFEST Tool Integration Framework eller iFEST IF.iFEST IF använder webbtjänster baserade på en standard som kallas OSCL, Open Services forLifecycle Collaboration samt specifikationer som gör att verktygen i verktygskedjan kankommunicera med varandra. För att validera ramverket har en fallstudie vid namn ”WindTurbine” gjorts med flertal inbyggda systemverktyg. Verktyg som används för att designa,implementera och testa en styrenhet för vindturbiner har integrerats i prototyp av enverktygskedja. För att bearbeta och behandla intern data genom webbtjänster behövs enverktygsadapter. Detta arbete redogör utvecklingen av en verktygsadapter förkravhanteringsmodulen HP Application Lifecycle Management (ALM), ett av de verktyg somanvänts i fallstudien av vindturbinen. En generalisering av de utmaningar som uppstod underutvecklingen av verktygsadaptern har genomförts. Dessa utmaningar indikerar att, trots att detfinns ett ramverk för verktygsintegration så är verktygsintegration fortfarande vara en svåruppgift att få bukt med. Detta gäller särskilt när verktyg inte är utvecklade med hänsyn tillverktygsintegration från början.

Full textAbstract:
It is important to promote a sustainable development approach to ensure that economic, environmental and social developments are maintained in balance. Sustainable development and its implications are not just a global concern, it also affects Australia. In particular, rural Australian communities are facing various economic, environmental and social challenges. Thus, the need for sustainable development in rural regions is becoming increasingly important. To promote sustainable development, proper frameworks along with the associated tools optimised for the specific regions, need to be developed. This will ensure that the decisions made for sustainable development are evidence based, instead of subjective opinions.
To address these issues, Queensland University of Technology (QUT), through an Australian Research Council (ARC) linkage grant, has initiated research into the development of a Rural Statistical Sustainability Framework (RSSF) to aid sustainable decision making in rural Queensland.
This particular branch of the research developed a decision support tool that will become the integrating component of the RSSF. This tool is developed on the web-based platform to allow easy dissemination, quick maintenance and to minimise compatibility issues. The tool is developed based on MapGuide Open Source and it follows the three-tier architecture: Client tier, Web tier and the Server tier. The developed tool is interactive and behaves similar to a familiar desktop-based application. It has the capability to handle and display vector-based spatial data and can give further visual outputs using charts and tables. The data used in this tool is obtained from the QUT research team. Overall the tool implements four tasks to help in the decision-making process. These are the Locality Classification, Trend Display, Impact Assessment and Data Entry and Update. The developed tool utilises open source and freely available software and accounts for easy extensibility and long-term sustainability.

Full textAbstract:
Dawson (2009) suggested a twelve step methodology for implementing knowledge management solutions following research which showed that implementing knowledge management solutions was not as successful as expected. This thesis investigates the third of this twelve step methodology which requires finding a knowledge management solution in the context of the problem. The aim of the research is to determine a methodology that will provide a systematic way for managers to select an appropriate knowledge management tool given a particular working environment. Two organisations are investigated to confirm that there is a need for a systematic methodology for selecting knowledge management tools and how a methodology may help in achieving selecting an appropriate tool. This investigation is carried out using case studies, action research and interviews and results in discovering that organisations do not have a systematic method for selecting tools which leads to tools being selected haphazardly and not always successfully. Two tools are developed to aid a manager in selecting a knowledge management tool: the House of Knowledge Management Tool Selection and the Knowledge Management Tool Classification Grid. The House tool helps to identify the knowledge problem being solved and evaluates all potential knowledge management tools against the problem. The barriers to the potential success of the tools are also examined. The grid identifies potential tools by classifying them against knowledge problems. The two tools are further refined and developed using the two organisations as case studies to demonstrate how and when the tools can be used. This leads to development of the Barrier House and the Evaluation Grid. A framework and associated methodology are then developed that can be used as a guide to using the tools, offering a systematic approach to selecting knowledge management tools given any environment and thus accomplishing the aim of the thesis.

Full textAbstract:
Wireless Sensor Networks (WSNs) are rapidly gaining popularity in various critical domains like health care, critical infrastructure, and climate monitoring, where application builders have diversified development needs. Independent of the functionalities provided by the WSN applications, many of the developers use visualization, simulation, and programming tools. However, these tools are designed as separate stand-alone applications, which force developers to use multiple tools. This situation often poses confusion and hampers an efficient development experience. To avoid the complexity of using multiple tools, a new, extensible, multi-platform, scalable, and open-source framework called PROVIZ is designed. PROVIZ is an integrated visualization and programming framework with the following features: PROVIZ 1) visualizes sensor nodes and WSN traffic by parsing the data received either from a packet sniffer (e.g., a sensor-based sniffer, or a commercial TI SmartRF 802.15.4 packet sniffer), or from a simulator (e.g., OMNeT); 2) visualizes a heterogeneous WSN consisting of different sensor nodes sending packets with different packet payload formats; and 3) provides a programming framework, which provides a graphical and script-based programming functionality, for developing WSN applications. Also, PROVIZ includes built-in extensible visual demo deployment capabilities that allow users to quickly craft network scenarios and share them with other users. Additionally, a secure and energy efficient wireless code dissemination protocol, named SIMAGE, was developed. SIMAGE is used by PROVIZ to wirelessly reprogram the sensor nodes. SIMAGE uses a link quality cognizant adaptive packet-sizing technique along with energy-efficient encryption protocols for secure and efficient code dissemination. In this thesis, the various features of PROVIZ's visualization and programming framework are explained, the functionality and performance of SIMAGE protocol is described, an example WSN security attack scenario is analyzed, and how PROVIZ can be used as a visual debugging tool to identify the security attack and aid in providing a software fix are discussed.

Full textAbstract:
Corporate sustainable development is placed between simplified interpretations and an overabundance of complexity and requirements that hampers implementation. Stakeholder Relations Management is one approach for the operationalization of sustainable development on the corporate level, which enables the inclusion of aspects of sustainability into corporate decision-making in a pragmatic way. However, stakeholder pressure and economic constraints lead companies to adopt only a small segment of the concept of sustainable development. Therefore, a referential framework is needed in order to regard corporate initiatives within the wider context of sustainable development on the theoretical level. The framework of sustainable development presented here, which was developed during a research project funded by the "Austrian Science Fund", takes the wide range of notions of sustainable development into account. Like a map, the framework depicts approaches to sustainable development and provides an overview of the aspects of sustainable development (scope) as well as the different levels of complexity that are associated therewith (depth). This framework is conceived as a tool to classify approaches to sustainable development in a wider context.

Full textAbstract:
Successful development of software systems depends on the quality of the requirements engineering process. Users oftoday's software systems expect systems to execute tasks on time, assure secure transactions, provide accurate results, and have low down-times. Therefore, capturing, representing, and addressing not only the functional requirements but also the non-functional requirements (NFRs) or quality requirements during software systems development is a pre-requisite to the development of effective and efficient software systems. Despite the critical importance of quality requirements, there is a considerable gap in the breadth and depth of quality engineering support in most Requirements Engineering (RE) methods. In practice, quality concerns are frequently considered only as an afterthought in the systems development process. Whilst there is a wealth of modelling formalisms and process models for functional requirements, there is very limited support for quality factors in requirements engineering. The objective of this research was therefore to investigate the use of quality ontologies to efficiently and effectively address quality requirements during the RE activities. The main contributions of this thesis are an ontology-based quality driven requirements engineering approach: the ElicitO framework and tool. The ElicitO framework consists of processes and guidelines on how to conduct RE stages supported by ontologies (domain and quality) implemented in the ElicitO tool. The framework and the tool are aimed at empowering requirements analysts with a knowledge repository that helps to capture precise non-functional requirements. Finally the ElicitO tool was evaluated in a University Web Project at the University of Manchester. The results of the case study indicate that quality requirements can be better understood, negotiated about, precisely captured and documented early in requirements engineering activities.

Full textAbstract:
Understanding the touchpoints of water usage metering and how meter data is used in all business areas of water utilities, and in the everyday lives of customers, can lead to an appreciation of the scale of obtainable benefits of digital water metering (DWM). The absence of a systematic cataloguing of benefits, and the measurement of their value to a water utility and its customers, may explain the lack of acceptance of this technology among water utilities.
Manual meter reading has been identified as inefficient and ineffective for most utility processes, other than periodic billing for which it too can be problematic. DWM substantially eliminates the walking of meter reading routes by meter readers. It delivers over 2000 readings per quarter (at hourly intervals) rather than just the one reading obtained by the meter reader. Special trips to the property, which are required to read the manual meter when the customer leaves, are also eliminated. Sometimes the customer is asked to read the meter when the water utility cannot. DWM is accurate and automatic whereas manual meter reading is subject to mis-reads and estimation when the meter cannot be accessed. In Australia, and many other parts of the developed world, few water utilities have switched to DWM completely and, in many others, only in particular circumstances, usually involving a lack of physical access or where access by meter readers would be inefficient. Where significant network issues or scarce water resources have existed, digital meters have improved the management of the network and allowed the deferral of network augmentation and the conservation of water.
This doctoral research study aimed to address this lack of knowledge of DWM benefits by searching for and cataloguing the benefits, and by developing plausible measures that provide probabilistic ranges of outcomes of savings and changes to customer sentiment. The objectives were to find as many benefits as possible from across water utilities’ operations and among customer interactions with their water and wastewater service provider; to value those benefits, particularly the less-tangible benefits: and to develop a tool to model the value of benefits for water utilities.
To identify the benefits, an extensive literature review of academic and industry reports was conducted. Interviews were conducted with several current and past staff of water utilities. The literature review was backed up by structured interviews with employees with specific expertise from a cross section of companies and representing various roles within those organisations. Customers were surveyed directly to identify their responses to the potential of digital metering. Qualitative and quantitative methods were applied to the expert opinions and customer survey responses to develop a valuation model that calculates savings and change in customer satisfaction levels. Other surveys were conducted to collect data from water utilities on specific issues. The valuation model was trialled in the field. The methods and findings are presented in the four journal papers that are included in this thesis.
In all, 77 benefits of DWM were identified. These were categorised into a taxonomy based on who would benefit, (i.e., the water business, the customer or both water business or customer) as well as the business areas and sub-areas of those beneficiaries. A second taxonomy was developed that categorised benefits according to sustainability themes. Qualitative analysis of the expert opinions regarding the benefits exposed the range of opinions on the likelihood that benefits could be achieved and the extent of the benefit. While quantifying the savings of individual benefits, two contexts were identified (Cost of Water savings, and Charges and Operational Cost savings) and the need for flexibility to meet local expectations was observed. The customer survey revealed the potential change in levels of customer satisfaction from a current 5.8 (0 – 10 scale) to between 6.2 and 8.8, with a simple average of 7.6. Separate valuation methods within the model were developed for each context. A third valuation method was developed for measuring change in customer satisfaction over multiple years. The application of the model, using a large metropolitan water utility’s data, calculated savings outcomes that were consistent with the utility’s cost-benefit analysis and provided the utility with risk-based probabilistic ranges. DWM benefit savings were also viewed through a sustainability lens after being allocated to the different sustainability themes. The trial raised issues with the framing of business cases for DWM projects and which were then examined.
Other findings were made during the study. The commonly used scale used in the Net Promoter Score classification of customers was observed to be inaccurate for relationship type surveys of water utilities, and a new scale was proposed. The potential of data analytics applied to hourly meter readings to answer questions on usage within residential properties was examined through a case study of a regional water utility. A model to optimise the sequencing of meter deployment to gain benefits early was proposed and a prototype model presented. Further, an opportunity for a capability model for intelligent metering was identified and a preliminary model was developed. The study also proposed that a longitudinal study of the uplift in customer satisfaction from the use of DWM be conducted, and that a non-monetary measure of the value of social equity be developed and applied to DWM project proposals.Thesis (PhD Doctorate)

Full textAbstract:
Organizations of all sizes collect a vast quantity of data every year. A data warehouse facilitates strategic multidimensional analysis on these data, by providing a single integrated queryable interface for multiple heterogeneous data sources. However, this interface is at the logical level schema, which fails to take advantage of the fundamental concepts of multidimensional data analysis like facts, dimensions, hierarchies, etc. In this thesis, we discuss a conceptual modeling language from the Conceptual Integration Modeling framework that serves multidimensional data to the users at a much higher level of abstraction. We not only provide the formal semantics for the language, but we also supply conceptual models depicting real world data analysis scenarios. These models are backed up with rigorous mathematical definitions to dispel any ambiguity in their interpretation. We developed a fully functional graphical editor, called the Model manager, to enable users to draw conceptual models visually.

Approved for public release; distribution is unlimitedTactical networks are becoming more critical in maintaining centers of gravity for military operations as cyberspace becomes contested at all levels of war. As a result, the growth of network centric operations and increased operational tempo in the cyber domain has created a significant training gap for tactical network administrators. This research suggests that a computer-based environment can integrate the operational network and a training network into the same system to allow tactical network administrators to concurrently administer the network and conduct realistic training on an identical virtual network. A review of commercial and open-source tools identifies the baseline for an architecture and framework for this system. The architecture consists of a modular design comprised of mapping, awareness, and virtualization modules. The framework integrates these modules by defining a network topology format, programming language, graphical user interface solution, and virtualization solution. This research concludes by providing an implementation that demonstrates desired capabilities. While we demonstrate that the project goals are attainable, there is a need for further research and development to deploy this capability to fleet units.

Dai, Xu. "Extended travelling fire method framework with an OpenSees-based integrated tool SIFBuilder." Thesis, University of Edinburgh, 2018. http://hdl.handle.net/1842/33088.
Full textAbstract:
Many studies of the fire induced thermal and structural behaviour in large compartments, carried out over the past two decades, show a great deal of non-uniformity, unlike the homogeneous compartment temperature assumption in the current fire safety engineering practice. Furthermore, some large compartment fires may burn locally and they tend to move across entire floor plates over a period of time as the fuel is consumed. This kind of fire scenario is beginning to be idealized as 'travelling fires' in the context of performance‐based structural and fire safety engineering. However, the previous research of travelling fires still relies on highly simplified travelling fire models (i.e. Clifton's model and Rein's model); and no equivalent numerical tools can perform such simulations, which involves analysis of realistic fire, heat transfer and thermo-mechanical response in one single software package with an automatic coupled manner. Both of these hinder the advance of the research on performance‐based structural fire engineering. The author develops an extended travelling fire method (ETFM) framework and an integrated comprehensive tool with high computational expediency in this research, to address the above‐mentioned issues. The experiments conducted for characterizing travelling fires over the past two decades are reviewed, in conjunction with the current available travelling fire models. It is found that no performed travelling fire experiment records both the structural response and the mass loss rate of the fuel (to estimate the fire heat release rate) in a single test, which further implies closer collaboration between the structural and the fire engineers' teams are needed, especially for the travelling fire research topic. In addition, an overview of the development of OpenSees software framework for modelling structures in fire is presented, addressing its theoretical background, fundamental assumptions, and inherent limitations. After a decade of development, OpenSees has modules including fire, heat transfer, and thermo‐mechanical analysis. Meanwhile, it is one of the few structural fire modelling software which is open source and free to the entire community, allowing interested researchers to use and contribute with no expense. An OpenSees‐based integrated tool called SIFBuilder is developed by the author and co‐workers, which can perform fire modelling, heat transfer analysis, and thermo-mechanical analysis in one single software with an automatic coupled manner. This manner would facilitate structural engineers to apply fire loading on their design structures like other mechanical loading types (e.g. seismic loading, gravity loading, etc.), without transferring the fire and heat transfer modelling results to each structural element manually and further assemble them to the entire structure. This feature would largely free the structural engineers' efforts to focus on the structural response for performance-based design under different fire scenarios, without investigating the modelling details of fire and heat transfer analysis. Moreover, the efficiency due to this automatic coupled manner would become more superior, for modelling larger structures under more realistic fire scenarios (e.g. travelling fires). This advantage has been confirmed by the studies carried out in this research, including 29 travelling fire scenarios containing total number of 696 heat transfer analysis for the structural members, which were undertaken at very modest computational costs. In addition, a set of benchmark problems for verification and validation of OpenSees/SIFBuilder are investigated, which demonstrates good agreement against analytical solutions, ABAQUS, SAFIR, and the experimental data. These benchmark problems can also be used for interested researchers to verify their own numerical or analytical models for other purposes, and can be also used as an induction guide of OpenSees/SIFBuilder. Significantly, an extended travelling fire method (ETFM) framework is put forward in this research, which can predict the fire severity considering a travelling fire concept with an upper bound. This framework considers the energy and mass conservation, rather than simply forcing other independent models to 'travel' in the compartment (i.e. modified parametric fire curves in Clifton's model, 800°C‐1200°C temperature block and the Alpert's ceiling jet in Rein's model). It is developed based on combining Hasemi's localized fire model for the fire plume, and a simple smoke layer calculation by utilising the FIRM zone model for the areas of the compartment away from the fire. Different from mainly investigating the thermal impact due to various ratios of the fire size to the compartment size (e.g. 5%, 10%, 25%, 75%, etc.), as in Rein's model, this research investigates the travelling fire thermal impact through explicit representation of the various fire spread rates and fuel load densities, which are the key input parameters in the ETFM framework. To represent the far field thermal exposures, two zone models (i.e. ASET zone model & FIRM zone model) and the ETFM framework are implemented in SIFBuilder, in order to provide the community a 'vehicle' to try, test, and further improve this ETFM framework, and also the SIFBuilder itself. It is found that for 'slow' travelling fires (i.e. low fire spread rates), the near‐field fire plume brings more dominant thermal impact compared with the impact from far‐field smoke. In contrast, for 'fast' travelling fires (i.e. high fire spread rates), the far‐field smoke brings more dominant thermal impact. Furthermore, the through depth thermal gradients due to different travelling fire scenarios were explored, especially with regards to the 'thermal gradient reversal' due to the near‐field fire plume approaching and leaving the design structural member. This 'thermal gradient reversal' would fundamentally reverse the thermally‐induced bending moment from hogging to sagging. The modelling results suggest that the peak thermal gradient due to near‐field approaching is more sensitive to the fuel load density than fire spread rate, where larger peak values are captured with lower fuel load densities. Moreover, the reverse peak thermal gradient due to near‐field leaving is also sensitive to the fuel load density rather than the fire spread rate, but this reverse peak value is inversely proportional to the fuel load densities. Finally, the key assumptions of the ETFM framework are rationalised and its limitations are emphasized. Design instructions with relevant information which can be readily used by the structural fire engineers for the ETFM framework are also included. Hence more optimised and robust structural design under such fire threat can be generated and guaranteed, where we believe these efforts will advance the performance‐based structural and fire safety engineering.

Many motor skills that people learn throughout their lives involve mastering a physical tool, such as riding a bike, writing with a pen, or playing basketball. When learning these skills, people often use physical learning aids to provide support. However, currently these learning aids only come in predefined levels. For instance, training wheels on a bike are either mounted or taken off. This jump from an easy task to a much harder one makes the transition difficult in learning the skill. In this thesis, we address this challenge by adapting the physical tool according to the learner's progress. For instance, while learning to ride a bike, we monitor learners' balancing skills and as they improve, we gradually lift the training wheels to reduce support and increase the difficulty. Thus, this approach enables a step-by-step transition from an easy to hard level that, like existing adaptive learning systems for math and language skills, is personalized for each individual learner. To illustrate this idea, we built an end-to-end system that allows designers to setup adaptable tools that physically change when a learner's skill level increases. This system uses sensors integrated with the tools to measure progress; parametric 3D modeling to adapt the tool; and either actuation or re-fabrication to deploy the physical change.

Full textAbstract:
Due to technological developments, apps (mobile applications) and web-based applications are now used daily by millions of people worldwide. Accordingly, such applications need to be usable by all groups of users, regardless of individual attributes. Thus, software usability measurement is fundamental metric that needs to be evaluated in order to assess software efficiency, effectiveness, learnability and user satisfaction. Consequently, a new approach is required that both educates software novice developers in software evaluation methods and promotes the use of usability evaluation methods to create usable products. This research devised a development framework and learning tool in order to enhance overall awareness and assessment practice. Furthermore, the research also focuses on Usability Evaluation Methods (UEMs) with the objective of providing novice developers with support when making decisions pertaining to the use of learning resources. The proposed development framework and its associated learning resources is titled dEv (Design Evaluation), and it has been devised in order to address the three key challenges identified in the literature review and reinforce by the studies. These three challenges are: (i) the involvement of users in the initial phases of the development process, (ii) the mindset and perspectives of novice developers with regard to various issues as a result of their lack of UEMs or the provision of too many, and (iii) the general lack of knowledge and awareness concerning the importance and value of UEMs. The learning tool was created in line with investigation studies, feedback and novice developers requirements in the initial stages of the development process. An iterative experimental approach was adapted which incorporated the use of interviews and survey-based questionnaires. It was geared towards analysing the framework, learning tool and their various effects. Two subsequent studies were carried out in order to test the approach adopted and provide insight into its results. The studies also reported on their ability to affect novice developers using assessment methods and also to overcome a number of the difficulties associated with UEM application. This suggested approach is valuable when considering two different contributions: primarily, the integration of software evaluation and software development in the dEv framework, which encourages professionals to evaluate across all phases of the development; secondly, it is able to enhance developer awareness and insight with regard to evaluation techniques and their application.

Full textAbstract:
Large public sector infrastructure projects are often characterized by a broad scope and capital dollar size, dynamic stakeholder and governance network, high project risk profile, long planning and procurement timelines, and high visibility to the public and political partisans. The number and breadth of risks during the planning and procurement phases that can delay project go-ahead or cause its ultimate cancelation are significant and thus require the utmost attention for successful delivery. The goal of this research was to improve risk management as it is applied in the delivery of large civil infrastructure with particular emphasis on the planning and procurement phases of public private partnerships and risks mainly internal to the client, in this case, the public sector organizations (e.g. end user and delivery organizations) involved. The research focused on developing a risk management framework, support tools and an improved research prototype that introduces the concept of characterizing different aspects of a project to improve the identification of risks and their related drivers, and elicitation of expert opinion of risk properties.
Understanding the unique characteristics of public sector large infrastructure project delivery was central in achieving this research goal and aspects were described in each of the chapters through case studies, observations and both formal and informal interviews with senior practitioners. The objectives of the thesis are summarized under three broad research themes: (1) Risk management practices and challenges in large infrastructure public projects; (2) Approaches to support elicitation of risk information to improve risk management processes; and, (3) Developing and gauging the effectiveness of a prototype integrated risk management tool. Thesis contributions are related to: (a) processes and risks encountered in the delivery of a public sector large infrastructure project in the planning and procurement phases; (b) strengths and weaknesses of the practitioner processes applied to carry out risk management in large infrastructure projects; (c) the multi-dimensionality of stakeholders involved in public sector project delivery; and (d) concepts and constructs developed to improve risk identification and the elicitation of expert opinion tasks applied in a prototype computer system.

Full textAbstract:
The identification of proper requirements is a key factor for a successful construction project. Many attempts in the form of frameworks, models, and tools have been put forward to assist in identifying those requirements. In projects using Building Information Modelling (BIM), the Employer Information Requirements (EIR) is a fundamental ingredient in achieving a successful BIM project. As of April 2016, Building Information Modelling (BIM) was mandated for all UK government projects, as part of the Government Construction Strategy. This means that all central Government departments must only tender with suppliers that demonstrate their capability on working with the Level-2 BIM. One of the fundamental ingredients of achieving the BIM Level-2 is the provision of full and clear Employer Information Requirements (EIR). As defined by PAS 1192-2, EIR is a "pre- tender document that sets out the information to be delivered and the standards and processes to be adopted by the suppler as part of the project delivery process". it also notes that "EIR should be incorporated into tender documentation to enable suppliers to produce an initial BIM Execution Plan (BEP)". Effective definition of EIRs can contribute to better productivity; within the budget and time limit set and improve the quality of the built facility. Also, EIR contribute to the information clients get at the end of the project, which will enable the effective management and operation of the asset at less cost, in an industry, where typically 60% of the cost go towards maintenance and operation. The aim of this research is to develop a better approach, for producing a full and complete set of EIRs, which ensures that the clients information needs for the final model delivered by BIM be clearly defined from the very beginning of the BIM process. It also manages the collaboration between the different stakeholders of the project, which allows them to communicate and deliver to the client's requirements. In other words, an EIR that manages the whole BIM process and the information delivered throughout its lifecycle, and the standards to be adopted by the suppliers as an essential ingredient for the success of a BIM project. For the research to be able to achieve the aims set and the formulated objectives, firstly a detailed and critical review on related work and issues was conducted. Then the initial design of the OntEIR Framework, which introduced the new categorisation system of the information requirements and the elicitation of requirements from high-level needs using ontology was presented. A research prototype of an online tool was developed as a proof-of- concept to implement and operationalise the research framework. The evaluation of the framework and prototype tool via interviews and questionnaires was conducted with both industry experts and inexperienced stakeholders. The findings indicate iv that the adoption of the framework and tool, in addition to the new categorisation system, could contribute towards effective and efficient development of EIRs that provide a better understanding of the information requirements as requested by BIM, and support the production of a complete BIM Execution Plan (BEP) and a Master Information Delivery Plan (MIDP).

A importância dos projetos de Tecnologia de Informação (TI) para os negócios aumentou e os resultados dos projetos impactam diretamente a estratégia e os lucros das empresas. Neste contexto, o processo de gerenciamento de risco pode ajudar gerentes de projeto a analisar as consequências das mudanças a serem feitas no objetivo e nas baselines dos projetos. O gerenciamento de riscos também permite aos gerentes de projetos a terem uma visão holística dos projetos. Apesar dos gerentes de projetos reconhecerem a importância do gerenciamento de riscos, muitos o fazem parcialmente, ou até mesmo não conseguem gerenciar os riscos devido às dificuldades diárias e à pressão do tempo. Plataformas wiki possuem algumas características herdadas das ferramentas Web 2.0 que podem ajudar gerentes de projetos no gerenciamento de riscos. Wikis também podem ajudar gerentes de projeto a envolver suas equipes e stakeholders nas discussões, na divulgação e no monitoramento dos riscos. Esta dissertação propõe um framework, chamado Wiki for Risk Management (W4RM), a ser adotado em gerenciamento riscos de projetos de TI. A pesquisa foi dividida em três estágios: revisão de literatura, grupo focal e entrevistas conduzidas a partir de abordagem metodológica construtivista. Esta pesquisa concluiu que gerentes de projetos enfrentam uma série de dificuldades ao gerenciarem, dificuldades estas já apontadas em por outros autores na área de gerenciamento de projetos. Os resultados indicam que devido às estas dificuldades, gerentes de projetos não conseguem gerenciar riscos em seus projetos como esperado. Uma importante contribuição desta pesquisa para a teoria é uma robusta análise dos problemas existente no gerenciamento de riscos. Outra contribuição teórica é o framework proposto para gerenciamento de riscos em projetos de TI. Uma contribuição para a prática é que o framework W4RM pode ser usado por profissionais em gerenciamento de projetos.
The importance of Information Technology (IT) projects for business is increasing and project results directly impact organizations’ strategy and performance. In this scenario, risk management processes can help project managers to analyze the consequences of changes on project goals and baselines. By managing risks, project managers can have a holistic view of projects. Despite project managers recognizing the importance of risk management, many of them only manage risks partially or even, skip this process due to daily difficulties and time pressure. Wiki platforms have some characteristics and principles inherited from Web 2.0 tools that can be useful when adopted on risk management. Wikis can help project managers evolve their teams and stakeholders on the process of identifying, reporting and monitoring risks on projects. This thesis proposes a framework - the Wiki for Risk Management (W4RM) - that can be used on risk management in IT projects. The process of designing the framework was divided into three stages: literature review, one focus group and interviews based on a constructivist methodological approach. This research points out that professionals face a series of difficulties as they engage on risk management, as previously argued by other authors on project management research area. Due to these difficulties, project managers are not able to manage risks as expected. An important theoretical contribution of this research is the robust analysis existing issues on risk management in IT settings. Another contribution of this thesis is the proposed framework for risk management for IT projects. For managerial implication of this research the W4RM framework that can be used by practitioners on project management.

Full textAbstract:
The proliferation of the Internet has amplified the use of social networking sites by creating a platform that encourages individuals to share information. As a result there is a wealth of information that is publically and easily accessible. This research explores whether open source intelligence (OSINT), which is freely available, could be used as a digital forensic investigative tool. A survey was created and sent to digital forensic investigators to establish whether they currently use OSINT when performing investigations. The survey results confirm that OSINT is being used by digital forensic investigators when performing investigations but there are currently no guidelines or frameworks available to support the use thereof. Additionally, the survey results showed a belief amongst those surveyed that evidence gleaned from OSINT sources is considered supplementary rather than evidentiary. The findings of this research led to the development of a framework that identifies and recommends key processes to follow when conducting OSINT investigations. The framework can assist digital forensic investigators to follow a structured and rigorous process, which may lead to the unanimous acceptance of information obtained via OSINT sources as evidentiary rather than supplementary in the near future.

Full textAbstract:
Background:
The development of bioinformatics databases, algorithms, and tools throughout the last years has lead to a highly distributedworld of bioinformatics services. Without adequatemanagement and development support, in silico researchers are hardly able to exploit the potential of building complex, specialized analysis processes from these services. The Semantic Web aims at thoroughly equipping individual data and services with machine-processable meta-information, while workflow systems support the construction of service compositions. However, even in this combination, in silico researchers currently would have to deal manually with the service interfaces, the adequacy of the semantic annotations, type incompatibilities, and the consistency of service compositions.
Results:
In this paper, we demonstrate by means of two examples how Semantic Web technology together with an adequate domain modelling frees in silico researchers from dealing with interfaces, types, and inconsistencies. In Bio-jETI, bioinformatics services can be graphically combined to complex services without worrying about details of their interfaces or about type mismatches of the composition. These issues are taken care of at the semantic level by Bio-jETI’s model checking and synthesis features. Whenever possible, they automatically resolve type mismatches in the considered service setting. Otherwise, they graphically indicate impossible/incorrect service combinations. In the latter case, the workflow developermay either modify his service composition using semantically similar services, or ask for help in developing the missing mediator that correctly bridges the detected type gap. Newly developed mediators should then be adequately annotated semantically, and added to the service library for later reuse in similar situations.
Conclusion:
We show the power of semantic annotations in an adequately modelled and semantically enabled domain setting. Using model checking and synthesis methods, users may orchestrate complex processes from a wealth of heterogeneous services without worrying about interfaces and (type) consistency. The success of this method strongly depends on a careful semantic annotation of the provided services and on its consequent exploitation for analysis, validation, and synthesis. We are convinced that these annotations will become standard, as they will become preconditions for the success and widespread use of (preferred) services in the Semantic Web

Den här rapporten avhandlar framtagandet av en prototyp för en tjänst där abonnenter hos telekomoperatörer ska kunna beställa och konfigurera sina egna tjänster i betydligt större utsträckning än vad som är möjligt idag.
Detta är möjligt och önskvärt tack vare att det pågår kontinuerlig modernisering av den teknik som idag används i telefonnät och telefonsystem.
Projektet genomfördes på uppdrag av Tieto i Kalmar som är ett konsultföretag som arbetar mycket med telekomteknik och som har flera stora kunder som arbetar med modernisering av sin teknik.
Resultatet har blivit en prototyp där användaren på ett flexibelt sätt kan skapa, redigera och radera sina egna tjänster, samt få en grafisk överblick över sina inställningar.
Prototypen är också enkel för uppdragsgivaren att anpassa för demonstration för olika kunder. Den är dessutom anpassad så att det ska gå så enkelt som möjligt att utveckla den vidare med nya komponenter.
Från början ingick en student från Rehabiliteringsprogrammet i projektet. Tanken var att kunna genomföra olika typer av användbarhetsanalyser och på så sätt göra prototypen så användarvänlig som möjligt. Då studenten av personliga skäl inte fullföljde projektet redovisas dessa delar av projektet inte i den här rapporten.
This thesis treats the development of a prototype for a service where telecom customers can order and configure their own services to a much higher degree than what is possible today.
This is possible and desireble due to a continuing modernisation of the technology beeing used in the telecom systems today.
The project was coducted on the request of Tieto, Kalmar. Tieto is a consulting company that is highly involved in the telecom industry and has several customers that are working with modernisation their technology.
The result is a prototype called: ”Effect: a prototype for an Easy to use, Flexible, Figurative, Extenable Configuration Tool”. It´s a web application where the users in a flexible way can order, configure and delete their own services, and also get an graphical overview of their settings.
The prototype is easy for Tieto to adjust when showing it to different customers. It is also adapted in a way that it is easy to extend it with new components.
In the beginning the project included a student från the Interaction design program. The idea was to conduct a series of usability analysis and with the help of that being able to make the prototype as user friendly as possible. Since the student, for personal reasons, did not finnish the projet, this report will not present anything on that part.

Full textAbstract:
In this dissertation we identify two problems with current integrated development
environments (IDEs) and present JQuery as a tool to address these issues.
The first problem is that IDE views answer low level questions and do not provide a mechanism to combine results to answer complex higher level questions. Even relatively simple questions force the developers to mentally combine results from different views.
The second problem is that IDEs do not provide an easy way to create perspectives on project specific concerns such as naming conventions or annotations. Most IDEs do offer support for creating custom perspectives but the effort required to create a perspective is considerably more than the benefit a custom perspective provides.
JQuery is an Eclipse plugin which generates code views using an expressive query language. We have redesigned JQuery to support a number of new user interface (UI) features and add a more flexible architecture with better support for extending the UI.
To address the first problem, we have added multiple views to JQuery where each view supports drag and drop of results, selection linking, and regular expression search. These features enable a user to combine results from different views to answer more complex higher level questions. To address the second problem, we can leverage the fact that JQuery is built on an expressive query language. Through this query language we are able to define project specific concerns such as naming conventions or annotations and then create views and perspectives for these concerns through the JQuery UI.

Full textAbstract:
This study is about the recruitment process. It started with a big picture of Work-life and narrowed down at the beginning of the career when candidates are applying for a job. There are different problems in the recruitment process. It is a stressful and uncertain experience for candidates. Also, the organizations will take damage by selecting an inadequate candidate. And, the recruiters have a hard time making a decent decision. This study investigates how to improve the experience of the stakeholders of candidates, organizations, and recruiters. The model of the design innovation process is the methodology of the project. The result is a candidate workshop framework that is a tool to get a deeper understanding of candidates. Designing a workshop can help to select an adequate person when there are the last few candidates. This workshop is complementary to a job interview, which can be before or after the job interview. It can be a physical or remote workshop. The workshop is about testing the abilities and soft skills that are not easy to measure by a traditional job interview. As a result, this solution can create an opportunity to gain better experience as teams and organizations meet people who are going to work with, and candidates get better feedback.

Full textAbstract:
An emerging problem in organisations is that there exist a large number of tools storing data that communicate with each other too often, throughout the process of an application or product development. However, no means of communication without the intervention of a central entity (usually a server) or storing the schema at a central repository exist. Accessing data among tools and linking them is tough and resource intensive. As part of the thesis, we develop a software (also referred to as ‘adaptor’ in the thesis), which, when implemented in the lifecycle management systems, integrates data seamlessly. This will eliminate the need of storing database schemas at a central repository and make the process of accessing data within tools less resource intensive. The adaptor acts as a wrapper to the tools and allows them to directly communicate with each other and exchange data. When using the developed adaptor for communicating data between various tools, the data in relational databases is first converted into RDF format and is then sent or received. Hence, RDF forms the crucial underlying concept on which the software will be based. The Resource description framework (RDF) provides the functionality of data integration irrespective of underlying schemas by treating data as resource and representing it as URIs. The model of RDF is a data model that is used for exchange and communication of data on the Internet and can be used in solving other real world problems like tool integration and automation of communication in relational databases. However, developing this adaptor for every tool requires understanding the individual schemas and structure of each of the tools’ database. This again requires a lot of effort for the developer of the adaptor. So, the main aim of the thesis will be to automate the development of such adaptors. With this automation, the need for anyone to manually assess the database and then develop the adaptor specific to the database is eliminated. Such adaptors and concepts can be used to implement similar solutions in other organisations faced with similar problems. In the end, the output of the thesis is an approachwhich automates the process of generating these adaptors.Resource Description Framework (RDF) ger funktionaliteten av dataintegration, oberoende av underliggande scheman genom att behandla uppgifter som resurs och representerar det som URI. Modellen för Resource Description Framework är en datamodell som används för utbyte och kommunikation av uppgifter om Internet och kan användas för att lösa andra verkliga problem som integrationsverktyg och automatisering av kommunikation i relationsdatabaser. Ett växande problem i organisationer är att det finns ett stort antal verktyg som lagrar data och som kommunicerar med varandra alltför ofta, under hela processen för ett program eller produktutveckling. Men inga kommunikationsmedel utan ingripande av en central enhet (oftast en server) finns. Åtkomst av data mellan verktyg och länkningar mellan dem är resurskrävande. Som en del av avhandlingen utvecklar vi en programvara (även hänvisad till som "adapter" i avhandlingen), som integrerar data utan större problem. Detta kommer att eliminera behovet av att lagra databasscheman på en central lagringsplats och göra processen för att hämta data inom verktyg mindre resurskrävande. Detta kommer att ske efter beslut om en särskild strategi för att uppnå kommunikation mellan olika verktyg som kan vara en sammanslagning av många relevanta begrepp, genom studier av nya och kommande metoder som kan hjälpa i nämnda scenarier. Med den utvecklade programvaran konverteras först datat i relationsdatabaserna till RDF form och skickas och tas sedan emot i RDF format. Således utgör RDF det viktiga underliggande konceptet för programvaran. Det främsta målet med avhandlingen är att automatisera utvecklingen av ett sådant verktyg (adapter). Med denna automatisering elimineras behovet att av någon manuellt behöver utvärdera databasen och sedan utveckla adaptern enligt databasen. Ett sådant verktyg kan användas för att implementera liknande lösningar i andra organisationer som har liknande problem. Således är resultatet av avhandlingen en algoritm eller ett tillvägagångssätt för att automatisera processen av att skapa adaptern.

In this dissertation System Dynamics is used as a modelling approach to model health care systems to gain a better understanding of the system’s behaviour. This improved understanding can be used to better manage the system and in turn will translate to improved health outcomes. The characteristics of complex systems were reviewed to define a health system as a complex system. Four appropriate modelling approaches was studied that could be used to model complex systems. These modelling approaches included: Monte Carlo Simulation, Discrete Event Simulation, System Dynamics and Agent Based Modelling. System Dynamics was identified as being the most appropriate modelling methodology to be used for the framework. Before the framework was developed health system performance measurement was reviewed to further the understanding of health system measurement. The framework was developed according to the insights gained from the previous reviews. Specifically the elements identification was customised to the health care environment based on available health indicators. The framework was applied in a case study where a section of the South Africa health care system was modelled to focus interventions for human immunodeficiency virus (HIV). The outcomes of the case studies delivered an increased understanding of the system behaviour and also showed appropriates of the framework.Dissertation (MEng)--University of Pretoria, 2012.

Full textAbstract:
There exist several methods, which can be used for evaluation of commercially available CASE-tools. Each method has its own focus and is based on specific underlying assumptions. There have been attempts to standardise evaluation of CASE-tools; however available methods differs much from each other.
One such method, named the 2G method has been proposed, which for each application, will establish a specific evaluation framework. This framework is tailored to the organisation at a specific point in time (since an organisation will change over time). The method consists of two phases which are iterated a sufficient number of times before a stable evaluation framework will be the result. The 2G method has been successfully applied on several applications in different organisations, though only for evaluation of CASE-tools before adoption. In this dissertation we report on an application of the 2G method, which aims to evaluate a CASE-tool from a company context which has already adopted a CASE-tool. As part of this method application the 2G method has also been transferred to the organisation.
An additional issue this dissertation addresses is what kind of support a general Qualitative Research Tool will offer a method user when using the tool in a 2G method application. Likewise the goal includes to establish is what is poorly or unsupported in such tool in a 2G application.
This dissertation will show that the 2G method is applicable also in a scenario where a CASE-tool has already been adopted, and therefore demonstrate that the method also is useful in evaluation studies performed after a CASE-tool has been adopted in an organisation. From the experiences of the application points will be made concerning what kind of support one would like to have in a qualitative research tool to simplify the work during the 2G applications.

Find full textAbstract:
Bus drivers have an extremely flexible working schedule, with shifts potentially differing from each day to the other. Unlike office schedules that are mostly 8 hours long, from morning to afternoon with a lunch break in between, a bus driver shift can start at any time in the day, have any number of breaks in between and have any possible duration, from a few minutes to a few hours. Driving vehicles full of passengers is a serious responsibility and making sure the driver is in the best possible shape is an obligation of the employer, in compliance with the current regulations about rests.
Nowadays this planning task in several companies is carried out by hand when possible and with huge excel sheets for more complex schedulings. The goal of this thesis is to describe the process of developing a graphical tool that assists bus companies in planning a fair and clean schedule for their drivers. This tool will also automatically validate drivers' resting times, duties distribution and coverage, overtime hours and fairness to evenly balance the daily and weekly workload, preventing some drivers to (unintentionally) have lighter or heavier shifts than others. Ensuring for drivers the best possible environment to work in is a solid starting point to have safe and on-time bus rides.

Full textAbstract:
A component-oriented tool for hierarchical modeling of instructional designs is developed. The motivation is to show that hierarchical representation of instructional designs is easier, better and more effective for modeling. Additionally a modeling language is developed to provide an effective, flexible and easy to use integration model in which all teaching components are discovered, defined and connected. In order to fulfill the above purposes an abstract notation is developed that is sufficiently general and adapting top-down hierarchic approach to represent Units of Learning (UoL), Operational Knowledge Units (OKU), Learning Objects (LO), and Learning Components (LC) with respect to the common structures found in different instructional models. COSEML, a top-down hierarchic, and component oriented modeling language has been used as a reference and the core concept in developing the Educational Component Oriented Modeling Language (ECOML). The high-level architecture of ECOML provides the means for designing instructional structures. It describes how LOs, UoLs, OKUs and LCs are sequenced in a certain context or knowledge domain. The resulting model can be reused in different contexts and across different educational platforms.

explosion in the use of computing and interactive systems of all kinds. This growth has brought with it an awareness among developers of interactive systems about the importance of user centered design and usability. In the Virginia Tech Usability tools lab, efforts are underway to develop tools and processes that assist in usability evaluation. This has led to the development of the User Action Framework (UAF) (Andre et al., 1999), a framework that forms the basis of several usability inspection tools like the Explorer, UPI (Usability Problem Inspector), UPC (Usability Problem Classifier) and the usability problem database. The UAF explorer is the tool in the toolkit, which allows users to explore and learn the structure of the UAF. The framework, in its final stages of development, is based on an interaction cycle derived from Norman's action model (1986). For its acceptance, the user action framework, which is based on human factors and cognitive concepts, needed a training program to make it accessible and understandable to the usability practioners in industry and academia.
This thesis addressed the following research activities: (1) Developing a web-based training tool for the User Action Framework explorer and (2) Evaluating a web- based training tool using various formative evaluation techniques and a final summative evaluation to measure effectiveness of the training, transfer of training, knowledge/skill acquisition and reaction to the training.
The summative evaluation used a pretest-posttest between subjects experimental design to determine the effectiveness of the training tool with the use of lecture-based training as a control group. The data collection included objective measures of performance and subjective measures through questionnaires and rating scales. The summative evaluation found no significant differences between gain scores on lecture-based training and web-based training under controlled conditions.
Opportunities for future research were identified and the training tool is expected to contribute to the efforts of the VT usability tools lab towards educating usability professionals and researchers alike on the usefulness of the User Action Framework and its associated tools. This work also seeks to proliferate the use of web based training methods as a valuable way to train remote learners on such developing frameworks and toolkits.Master of Science

Full textAbstract:
Laws and regulation affect software development, as they frequently demand changes in software’ requirements to protect individuals and businesses regarding security, privacy, governance, sustainability and more. Legal requirements can dictate new requirements or constrain existing ones. The problem of software compliance is howto ensure that the software complies with the norms that the legislation imposes. The problem is particularly challenging because it combines difficultsteps: 1)analyze legal documents, 2) extract requirements from those documents, 3) identify conflicting requirements with those already implemented in software and 4) ensure that software remains compliant even with the changes. Compliance is a continuous process: laws, software and the context within which software system operates changes
continuously. The works dealing with the compliance problem focus only on one or two subjects: analyze legal documents or extract requirements or identify conflicts or changes. This thesis deals with all the problems at the same time; the idea is to extract requirements
from legal text, compare them with the software requirement, resolve the possible conflicts that may arise, continuously leading with the changes on environment, laws and requirements. For this, this work proposes a framework that is composed of a compliance process and continuous monitoring of environmental changes. The framework deals with different types of laws (security, privacy, transparency, health care) that are represented in explicit norms. The compliance process supports the identification, extraction, comparison and conflict resolution to help software compliance, by producing a compliant set of requirements. The compliance process is based on the semantic annotation and goal model. The semantic annotation helps to extract requirements from thelaw, using patterns. The goal model is used to help the comparison between requirement and to represent requirements in a formal and consistent requirement specification. The process is tool supported; some tools were reused (Desiree and NomosT) to further each step. It was necessary to adapt the tools for the context of the
compliance process, creating a guideline, patterns, and heuristics. The continuous monitoring is concerned about the changes that affect the software compliance and has 7 the mechanism to ensure that even with those changes the software will regain compliance. The compliance monitor is basedon agents and Non Functional Requirements. The agents are represented using in i*, the idea is to showthe collaboration
between the agents to ensure the continuous compliance. The requirement specification of how each agent should behave was also generated using Business Process Modeling Notation and Desiree language. The Non Functional Requirements catalogue is used to
help to define operalizations for the software awareness. The framework validation was made in two parts: first, the compliance process and after all the framework proposed. For the compliance process, the effort and correctness were measured comparing the use of the proposed process andan ad-hoc method. For the entire framework, the example of monitoring the changes in the environment when an automated car is crossing the border between Washington and Canada was used. The study shows that context has a strong influence on the software requirements, and nonconformity problems may incur penalties. The contribution of this work is the Eunomia framework that has a process and goal model perspective with emphasis on monitoring that helps to deal with the compliance challenge. The framework equips the requirements engineering team with a systematic method. Eunomia framework is a tool-supported and systematic process which can be reused to reduce the time effort and to improve the quality of the requirement specification that helps to create a compliant software requirement specification that is compliant over the time.

Scholars widely accept that the well-documented benefits of biophilia–the human being's strong urge to connect with nature–are genuine to improved health. Then why, with the global acceptance and scientific validity of wellness design concepts, do architects not use this beneficial concept regularly–especially when designing isolated workspaces? This qualitative research explores architecture's current design decision process to better understand this design phenomenon, and to identify where architectural biophilic knowledge domains may be deficient. This study explores questions such as: Does the architect's lack of biophilic knowledge and/or structured wellness design decision support framework affect the decision? Would the existence of a wellness design tool better support the design decision? An explanatory case study using a purposeful study sample of architects, biophilia design experts, and associated specialists is used to develop design decision support frameworks. Level 1 establishes a propositional theory derived from the literature and professional experience, level 2 from architect interviews and observational meetings, and level 3 from a Delphi workgroup session. Framework evolutions help identify design-phase-specific knowledge gaps. This study finds that a deficiency in early exposure to a priori, explicit and tacit biophilic knowledge is creating a critical gap, thus diminishing a posteriori biophilic knowledge and research in the architecture profession.

Few will dispute that the well-documented benefits of biophilia–the human being's strong urge to connect with nature–are genuine to improved health. Then why, with the global acceptance and scientific validity of wellness design concepts, do architects not use this beneficial concept regularly–especially when designing windowless workspaces? A qualitative explanatory case study using a purposeful study sample of architects, biophilia design experts, and associated specialists was used to develop a design decision support framework that evolved from level 1-3. Framework progressions helped identify specific knowledge gaps in each design phase. This study found that a deficiency in early exposure to a priori, explicit and tacit biophilic knowledge is creating a critical gap, thus diminishing a posteriori biophilic knowledge and research in the architecture profession. This study asserts that early exposure to biophilic theories and principles can enhance the profession and provide a knowledge bridge using an informed biophilia design decision support framework with a proposed biophilia project management tool.

Full textAbstract:
Previous research has typically focused on singular attributes that impact a leader’s effectiveness. This study, instead, looks at whether emotional intelligence moderates the anticipated negative effect of distributed presence on engagement and influence, and ultimately, leader effectiveness. Buttressed by emotional intelligence, engagement, and influence theories, the research question focused on how emotional intelligence skills moderate the impact of a project manager’s distributed presence to render the leader effective. The study sample for this research came from voluntary participants who work for a U.S. government agency comprising leaders co-located with their teams and distributed presence leaders. Descriptive statistics showed that leaders with higher emotional intelligence (EI) were more engaging and influential than co-located leaders with high EI. Regression analyses indicated greatest significance between the dependent variables—engagement and influence—and the independent variables of distributed presence and emotional intelligence when using emotional intelligence branches and tasks for the EI variables. Data from this study showed distributed presence leaders with high emotional intelligence abilities effect engagement and influence positively. The work of this research advances insights into how emotional intelligence effects, positively, project leader engagement and influence when the project manager’s presence is distributed. The data rendered by this research was informative but only to a limited degree because results were not sufficiently expansive. Nonetheless, the application of this study applies to the practical world as distributed teams seems to be a more permanent part of the business landscape than temporary, and learning how to better work as a project manager with distributed presence is essential for both organizations and project managers.

Full textAbstract:
Brisbane City Hall (BCH) is arguably one of Brisbane’s most notable and iconic buildings. Serving as the public’s central civic and municipal building since 1930, the importance of this heritage listed building to cultural significance and identity is unquestionable. This attribute is reflected within the local government, with a simplified image of the halls main portico entrance supplying Brisbane City Council with its insignia and trademark signifier. Regardless of these qualities, this building has been neglected in a number of ways, primarily in the physical sense with built materials, but also, and just as importantly, through inaccurate and undocumented works. Numerous restoration and renovation works have been undertaken throughout BCH’s lifetime, however the records of these amendments are far and few between. Between 2010 and 2013, BCH underwent major restoration works, the largest production project undertaken on the building since its initial construction. Just prior to this conservation process, the full extent of the buildings deterioration was identified, much of which there was little to no original documentation of. This has led to a number of issues pertaining to what investigators expected to find within the building, versus what was uncovered (the unexpected), which have resulted directly from this lack of data. This absence of record keeping is the key factor that has contributed to the decay and unknown deficiencies that had amassed within BCH. Accordingly, this raises a debate about the methods of record keeping, and the need for a more advanced process that is able to be integrated within architectural and engineering programs, whilst still maintaining the ability to act as a standalone database. The immediate objective of this research is to investigate the restoration process of BCH, with focus on the auditorium, to evaluate possible strategies to record and manage data connected to building pathology so that a framework can be developed for a digital heritage management system. The framework produced for this digital tool will enable dynamic uses of a centralised database and aims to reduce the significant data loss. Following an in-depth analysis of this framework, it can be concluded that the implementation of the suggested digital tool would directly benefit BCH, and could ultimately be incorporated into a number of heritage related built form.

Full textAbstract:
There is currently no set standard for evaluating visualization environments. Even though the number of visualizations has increased, there is a tendency to overlook the evaluation of their usability. This thesis investigates how a visualization tool for crowd trajectory data can be made using the visualization technique of animated maps and the JavaScript library D3.js. Furthermore it explores how such a visualization tool can be evaluated according to a suggested framework for spatio-temporal data. The developed tool uses data taken from the UCY Graphics Lab, consisting of 415 trajectories collected from a video recorded at a campus area. User evaluation was performed through a user test with a total of six participants, measuring effectiveness as completed tasks, and satisfaction as ease of use for three different amounts of trajectories. Qualitative data was recorded through using the think aloud protocol to gather feedback to further improve the implementation. The evaluation shows that the visualization tool is usable and effective, and that the technique of animated maps in combination with a heatmap can aid users when exploring and formulating ideas about data of this kind. It is also concluded that the framework is a possible tool to utilize when validating visualization systems for crowd trajectory data.Det finns i dagsläget ingen etablerad standard för att utvärdera visualiseringssystem. Även om antalet visualiseringar har ökat finns det en tendens att förbise utvärderandet av deras användbarhet. I det här arbetet undersöker vi hur ett visualiseringsverktyg för data av gångbanor hos folksamlingar kan skapas, med hjälp utav visualiseringsmetoden animated maps och JavaScript-biblioteket D3.js. Vidare undersöker vi hur det är möjligt att evaluera ett visualiseringsverktyg utefter ett givet ramverk. Visualiseringsverktyget använder data från UCY Graphics Lab. Datan består av 415 gångbanor som är insamlade från en videoinspelning av ett campusområde. En utvärdering genomfördes sedan med sex deltagare, där visualiseringens effektivitet och användarvänlighet mättes. Frågorna ställdes för tre olika mängder av gångbanor. Kvalitativa data dokumenterades genom en så kallad ''think aloud'', för att ge återkoppling och förslag på möjliga förbättringar av visualiseringen. Evalueringen visar på att animated maps i kombination med en heatmap kan hjälpa användare att utforska data av gångbanor hos folksamlingar, samt att verktyget är effektivt och användbart. Det är också visat att det ramverk som användes vid evalueringen är ett möjligt verktyg för att validera visualiseringsverktyg av den typ som gjorts i det här projektet.

Uncertainty in geospatial data fusion is a major concern for scientists because society is increasing its use of geospatial technology and generalization is inherent to geographic representations. Limited research exists on the quality of results that come from the fusion of geographic data, yet there is extensive literature on uncertainty in cartography, GIS, and geospatial data. The uncertainties exist and are difficult to understand because data are overlaid which have different scopes, times, classes, accuracies, and precisions. There is a need for a set of tools that can manage uncertainty and incorporate it into the overlay process. This research explores uncertainty in spatial data, GIS and GIScience via three papers. The first paper introduces a framework for classifying and modeling error-bands in a GIS. Paper two tests GIS usersâ ability to estimate spatial confidence intervals and the third paper looks at the practical application of a set of tools for incorporating uncertainty into overlays. The results from this research indicate that it is hard for people to agree on an error-band classification based on their interpretation of metadata. However, people are good estimators of data quality and uncertainty if they follow a systematic approach and use their average estimate to define spatial confidence intervals. The framework and the toolset presented in this dissertation have the potential to alter how people interpret and use geospatial data. The hope is that the results from this paper prompt inquiry and question the reliability of all simple overlays. Many situations exist in which this research has relevance, making the framework, the tools, and the methods important to a wide variety of disciplines that use spatial analysis and GIS.Ph. D.

Full textAbstract:
As fluorescent imaging techniques for biological systems have advanced in recent years, scientists have used fluorescent imaging more and more to capture the state of biological systems at different moments in time. For many researchers, analysis of the fluorescent image data has become the limiting factor of this new technique. Although identification of fluorescing neurons in an image is (seemingly) easily done by the human visual system, manual delineation of the exact pixels comprising these fluorescing regions of interest (or fROIs) in digital images does not scale up well, being time-consuming, reiterative, and error-prone. This thesis introduces NEPIC, the Neuron-to- Environment Pixel Intensity Calculator, which seeks to help resolve this issue. NEPIC is a semi-automated tool for finding and tracking the cell body of a single neuron over an entire movie of grayscale calcium image data. NEPIC also provides a highly extensible, open source framework that could easily support finding and tracking other kinds of fROIs. When tested on calcium image movies of the AWC neuron in C. elegans under highly variant conditions, NEPIC correctly identified the neuronal cell body in 95.48% of the movie frames, and successfully tracked this cell body feature across 98.60% of the frame transitions in the movies. Although support for finding and tracking multiple fROIs has yet to be implemented, NEPIC displays promise as a tool for assisting researchers in the bulk analysis of fluorescent imaging data.

Nos últimos quarenta anos, o Método do Quadro Lógico (MQL) vem sendo utilizado como modelo para o planejamento, execução e avaliação de projetos de desenvolvimento, por agências bilaterais, multilaterais, organizações governamentais e não governamentais. A condução de projetos com o apoio do método forneceu subsídios para a evolução do conceito original, ramificando-se em novos modelos e instrumentos, mas seu instrumento principal, o Quadro Lógico, permaneceu sendo empregado, apesar de algumas pequenas alterações. Durante seu período de maior evolução, os anos 1990, algumas fortes críticas questionaram a efetividade do método, mas não chegaram a abalar seu uso, pois a quantidade de usuários continuou a crescer. As críticas serviram para reflexão. Com a criação e evolução de outras ferramentas de gerenciamento de projetos, foi possível a assimilação do uso de componentes desses modelos para, em conjunto com o MQL, proporcionar melhorias no seu uso, tornando-o ainda mais consistente. O propósito desse trabalho foi, após diferenciar as características de projetos empresariais de projetos de desenvolvimento, considerando o largo uso do Project Management Body of Knowledge (PMBOK) nas Américas, avaliar as potenciais contribuições que esse conjunto de ferramentas, mais utilizado para projetos empresariais, pode proporcionar ao MQL, abordando diretamente seus pontos fracos e desvantagens e demonstrando as maneiras como o PMBOK pode contribuir para minimizar suas fraquezas e vulnerabilidades.
In the last forty years, the Logical Framework Approach (LFA) has been used as a model for the planning, implementation and evaluation of development projects by bilateral and multilateral agencies, governmental and nongovernmental organizations. Conducting projects with the support of the approach provided subsidies for the evolution of the original concept, branching into new models and tools, but its main instrument, the Logical Framework, remained running, despite some little changes. During its period of greatest development, the 1990s, some strong criticism questioned the effectiveness of the method, but failed to affect its use, since the number of users continued to grow. The criticisms served to reflection. With the creation and evolution of other project management tools, it was possible to assimilate the use of components of these models, in conjunction with the LFA, providing improvements in its use, and making it more consistent. The purpose of this study was, after contrasting the characteristics of business projects and development projects, and considering the wide use of the Project Management Body of Knowledge (PMBOK) in the Americas, to evaluate the potential contributions that this set of tools can provide to the LFA, directly addressing its weaknesses and drawbacks and demonstrating the ways in which PMBOK can help to reduce its vulnerabilities.

Full textAbstract:
Mestrado em MicrobiologiaFreshwater ecosystems have been suffering severe degradation and loss of biodiversity, caused by human disturbances such as agriculture, industry, mining, urban development and climate changes. Therefore, the European Union reached an agreement and implemented the Water Framework Directive (WFD), with the main goal of reach a good ecological status in all water bodies. However, WFD is very complex, methodologies are time-consuming and costly. Thus, the main objective of this study is to develop a rapid and cost-effective approach, by studying the bacterial community composition by flow cytometry, as a complementary methodology to WFD. To achieve this, we study 3 sampling sites at Caima River along the seasons (winter, spring and summer), with different levels of environmental impacts (Nascente- river source- with little impact, Bustelo- downstream WWTP and Palhal- exposed to mine drainage), applying first the WFD criteria and then multivariate analysis for macroinvertebrate, periphyton and bacteria communities. Physico-chemical, metals and bacteria samples were collected from the water column and sediment river bottom, showing that in all the parameters (with some exceptions) and metals the concentrations were higher in sediments. Results showed that not always the macroinvertebrate and periphyton communities were sensitive to an increased nutrient input, resulting in an ecological status higher than expected. On the other hand, community structure analysis for macroinvertebrates and periphyton was very discriminatory, associating high levels of nutrients and metals with more tolerant organisms in impacted sites, and sensitive organisms with high levels of dissolved oxygen corresponding to pristine environments. Bacteria community analysis revealed a clear separation of LNA and HNA bacteria in sediment according to the different environmental stress, being possible to dissociate the majority of the impacted sites from the clean sites, being HNA a good indicator of contamination. These results revealed that bacteria community in sediments has more reliable data about the impacts that a freshwater ecosystem can suffer. The discriminating power of bacteria community analyzed by FCM provided good responses, although, further investigations are needed to confirm the feasibility of this new method, as a complementary tool in the water quality assessment.
Os sistemas aquáticos de água doce têm vindo a sofrer uma severa degradação e perda de biodiversidade, derivado de atividades humanas como a agricultura, indústria, atividades mineiras desenvolvimento urbano e alterações climáticas. Assim, a União Europeia implementou a Diretiva Quadro da Água (DQA), com o principal objetivo de atingir o bom estado ecológico em todas as massas de água. No entanto, a DQA revelou ser bastante complexa, com metodologias muito morosas e dispendiosas. Com este estudo, pretende-se desenvolver uma metodologia rápida e económica, estudando a composição da comunidade bacteriana por citometria de fluxo, como ferramenta complementar à DQA. Para a concretização deste trabalho, foram estudados 3 locais do rio Caima com diferentes tipos de impactos: a nascente – local de referência; Bustelo - a jusante de uma estação de tratamento de águas residuais e o Palhal - com escorrências provenientes de uma mina desativada, no inverno, primavera e verão aplicando a metodologia estabelecidas pela DQA usando os macroinvertebrados e perifiton como comunidades biológicas estudadas. Adicionalmente foi aplicada a análise multivariada aos dados recolhidos por citometria de fluxo à comunidade de bactérias da coluna de água e dos elutriados dos sedimentos e aos resultados das comunidades de macroinvertebrados e perifiton obtidos da DQA. No geral, os parâmetros físico-químicos, e as quantificações de metais mostraram valores mais elevados nos elutriados dos sedimentos do rio, do que na coluna de água mostrando a importância da análise desta matriz que não está contemplada na DQA. Resultados sensu DQA mostraram que nem sempre as comunidades de macroinvertebrados e perifiton foram concordantes na resposta aos diferentes tipos de impactos e que a qualidade ecológica dos locais avaliados foi melhor do que era expectável. Por outro lado, a análise multivariada das comunidades de macroinvertebrados e perifiton foi bastante discriminatória, associando elevados níveis de nutrientes e metais com organismos mais tolerantes, que se encontram em locais mais impactados, e organismos sensíveis com altos níveis de oxigénio dissolvido em locais mais pristinos. A análise da comunidade bacteriana revelou uma distinta separação entre bactérias LNA e HNA nos sedimentos, de acordo com os diferentes stresses ambientais, sendo HNA, nos sedimentos, um ótimo indicador de contaminação. Estes resultados revelam que a comunidade bacteriana oferece uma boa resolução de locais contaminados usando a citometria de fluxo como metodologia rápida de avaliação complementar à avaliação do estado ecológico sensu DQA sendo, no entanto, necessárias mais estudos aplicados a outras tipologias de rios e outros tipos de impactos para confirmar a validade desta nova metodologia.

Full textAbstract:
Reflecting on the concept of well-being has been proven to be a crucial activity in sustainability endeavours. In the present society, well-being has been defined and promoted through an economic perspective. Measurements such as GDP and economic growth have been perceived as a determinant of welfare. This has led people to believe that having money and material goods are key to achieve well-being. This consumerist lifestyle has caused people to disconnect from nature and stop considering it as essential in order to have a happy and healthy life with high levels of well-being. By analysing this problem, we realized that if we want to live a sustainable life, we cannot continue viewing well-being through this lens. This problem is shown in the tension between the predominant capitalistic vision of well-being and alternative sustainable well-being theories, such as the well-established Māori framework. As researchers, we were wondering how we can redirect this discourse by placing future sustainability managers within this tension. To explore this, we engage in co-creating well-being narratives with 11 sustainability master students at Uppsala University Campus Gotland. How can the conversations with them around well-being drive a sustainable transformation? We discuss the participants’ thoughts and feelings during the interview process to investigate the influence of well-being conversation on generating a sustainable discourse. We found that joining the two concepts of well-being and sustainability through a narrative approach creates a powerful tool in driving change towards putting the priority back on nature.
