The widespread adoption of LMSs raises the need to evaluate the quality in use of these platforms through attributes such as usability and User eXperience (UX). For instance, if the LMS does not provide a good usability, the learner will spend more time trying to understand how to use the platform rather than learning the educational content. Similarly, a positive UX is essential to make the platform more pleasuring, appealing and satisfactory to the learner. Although several studies have been conducted to evaluate LMSs, few techniques encompass both usability and UX. This work presents the development of a technique to evaluate the usability and UX of LMSs, called TUXEL, by means of Design Science Research methodology. Additionally, we developed a tool to support the evaluation process. We conducted two empirical studies in order to assess the feasibility of the technique, while comparing it with an existing technique from the literature. Results indicated that TUXEL allowed identifying a higher number of usability problems in comparison to an adapted version of the Heuristic Evaluation, while requiring less time. / .

O objetivo desta tese de doutorado foi desenvolver modelos de previsão de desempenho de pavimentos asfálticos para a malha rodoviária do Estado da Bahia. Os modelos de desempenho foram desenvolvidos para pavimentos em concreto asfáltico usinado a quente e em tratamento superficial duplo. Foram utilizadas informações de um banco de dados de gerência de rodovias do DERBA, coletados em 2004, e foram coletados dados complementares de irregularidade longitudinal em 2009, após o desenvolvimento de um planejamento fatorial específico para essa finalidade. Foram utilizadas duas formas de análise estatística dos dados para avaliar a significância dos fatores e definir os parâmetros dos modelos de desempenho: a Análise Exploratória de Dados (AED) e a Análise da Variância (ANOVA). Os fatores considerados foram a idade do pavimento, o tráfego e a pluviometria e os resultados da análise exploratória de dados corroboraram os resultados encontrados pela análise da variância, tanto em relação aos efeitos dos fatores como das interações. Os modelos de previsão do desempenho foram desenvolvidos para as variáveis dependentes Índice de Condição do Pavimento Flexível (ICPF) e Área Total de Trincas (ATT), para os pavimentos em concreto asfáltico usinado a quente, e os modelos de previsão de desempenho de Área de Desgaste (ADesg) e Irregularidade Longitudinal (IRI BA), para os trechos em tratamento superficial duplo. Para a irregularidade longitudinal, também foram desenvolvidos modelos de desempenho em separado, para regiões de clima semiárido a seco (IRIBAs) e clima subúmido a úmido (IRI BAÚ). Para a verificação da adequação dos modelos de previsão de desempenho foram utilizadas a análise de resíduos, o coeficiente de correlação (r) e o coeficiente de determinação (\'R POT.2\'). Os modelos de desempenho, desenvolvidos neste trabalho para a Área Total de Trinca (ATT) e para a Irregularidade Longitudinal, foram comparados com modelos de desempenho empíricos, utilizados em programas de gerência de pavimentos por organismos rodoviários, do Brasil e do exterior, e apresentaram melhores resultados. O modelo de Irregularidade Longitudinal (IRI BA) para a rede de rodovias em tratamento superficial duplo também foi comparado com modelo desenvolvido pelo Departamento de Infraestrutura de Transportes da Bahia - DERBA, com base em levantamentos para a priorização de trechos candidatos a atividades de manutenção e reabilitação, e apresentou melhor ajuste aos dados observados. No entanto, para que sejam obtidos ainda melhores resultados, quanto à previsão de desempenho dos pavimentos da rede de rodovias pavimentadas do Estado da Bahia, é necessário que sejam realizados novos levantamentos para alimentação do banco de dados, sugerindo-se estudos complementares que incluam fatores que não puderam ser considerados neste trabalho, como a capacidade estrutural, por exemplo. Recomenda-se que o método utilizado neste trabalho, baseado no planejamento fatorial, na Análise Exploratória de Dados e na Análise de Variância, seja repetido, pois se mostrou capaz de reduzir os custos da coleta de dados sem comprometer a precisão e acurácia dos modelos de desempenho obtidos. / The objective of this thesis was to develop performance prediction models for asphalt pavements in the State of Bahia. The performance models were developed for hot-mix asphalt (HMA) and double surface treatment (ST). Information was obtained from a database maintained by DERBA (State of Bahia Department of Transportation), with data collected in 2004, and from additional collection of data, mainly of pavement roughness, performed in 2009 and that was based on an experimental design for this specific purpose. Two statistical analyses were used to assess the significant factors and define the parameters of the performance models: Exploratory Data Analysis (EDA) and Analysis of Variance (ANOVA). The factors considered were age of the pavement, traffic volume and rainfall, and the results of the exploratory data analysis corroborated the results found by the analysis of variance, both in relation to the effects of factors such as of their interactions. The performance prediction models were developed for the dependent variables Pavement Condition Index (PCI) and Area of Total Cracks (ATC) for HMA pavements, and Raveling (R) and roughness (IRI BA) for ST pavements. For roughness, performance models were also developed considering, separately, two climate conditions: semiarid to arid (IRI BAa) and sub-humid to humid (IRI BAh). Residue analysis and calculation of correlation coefficient (r) and coefficient of determination (\'R POT.2\') were performed to verify the adequacy of performance prediction models. The performance models developed in this work for Area of Total Cracks (ATC) and roughness (IRI) were compared with empirical performance models used for pavement management in Brazilian and foreign highway agencies, and they presented the best results. The performance model for roughness (IRI BA) in ST pavements was also compared to a prediction model developed by DERBA using data collected by a maintenance and rehabilitation activities prioritization program and it presented the best fit to the observed data. However, to obtain even better results regarding the performance prediction of asphalt pavements in the State of Bahia, it is necessary to conduct new field surveys to feed the database and be used in further studies that include factors that could not be considered in this work, as structural capacity, for example. It is recommended that the method used in this work, based on factorial design, Exploratory Data Analysis and ANOVA, be repeated, because it proved capable of reducing the costs of data collection without compromising precision and accuracy of the obtained performance prediction models.

O Índice de Condição do Pavimento (ICP), também apresentado como um índice de defeitos combinados, é, em muitos Sistemas de Gerência de Pavimentos Urbanos (SGPU), o único indicador da qualidade do pavimento dos segmentos que compõem a malha viária. Este trabalho é baseado em conceitos gerais, utilizando os tipos de defeito de pavimentos flexíveis do Programa SHRP (Strategic Highway Research Program), bem como a forma de quantificação da severidade e extensão com que se manifestam na superfície dos pavimentos, mas propõe um novo método para determinação de um Índice de Condição de Pavimentos Urbanos (ICPU), que considera as condições particulares de projeto, materiais, técnicas construtivas, controle de qualidade e políticas de manutenção e reabilitação da cidade em que está sendo implantado. O cálculo do ICPU é desenvolvido em três etapas, em que primeira calcula o peso por tipo de defeito, a partir de questionários preenchidos por profissionais da área de infraestrutura de transportes. A segunda etapa define fatores de ponderação para os pesos, por tipo de defeito e em função da severidade. A terceira e última etapa do método consiste na análise de correlação entre segmentos representativos da malha viária urbana em análise, o que, no estudo de caso desenvolvido neste trabalho, utilizou 10.402 de um total de 111.497 segmentos do Distrito Federal do Brasil, distribuídos entre as trinta regiões administrativas, incluindo Brasília, que foram avaliadas, subjetiva e objetivamente, nos anos de 2010 a 2012, pela Companhia Urbanizadora da Nova Capital do Brasil (NOVACAP), e que permite a determinação dos fatores de ponderação em função da extensão, por tipo de defeito. / The Pavement Condition Index (PCI), also presented as an index of combined defects, is, in many Urban Pavement Management Systems (UPMS), the only indicator of pavement condition for the segments of the urban roadway network. This work is based on general concepts, using the flexible pavement distress types of the SHRP Program (Strategic Highway Research Program), as well as the way to evaluate the severity and extent to which they manifest on the pavement surface, but proposing a new method for determining an Urban Pavement Condition Index (UPCI), which considers the particular conditions of design, materials, construction techniques, quality control and policies of maintenance rehabilitation of the city in which it is being implemented. The calculation of the UPCI is developed in three stages, in which the first calculates the weight by defect type, from questionnaires completed by professionals in the transport infrastructure area. The second stage sets weighting factors for the weights by distress type depending on the severity. The third and final step of the method consists in the analysis of correlation between representative segments of the urban roadway network in question, which, in the case study developed in this study, used a total of 10,402 among 111,497 segments of the Federal District of Brazil, distributed among the thirty administrative regions, including Brasilia, which were evaluated subjectively and objectively, in the years 2010-2012, by the Urbanization Company of the New Capital of Brazil (NOVACAP), which allows the determination of the weighting factors depending on of the distress type as a function of the extension.

Since last four to five years the buzz of continuous growing of agile development has been spread all around the world, specially Extreme Programming as the most important methodology of this kind. From the other side, ISO 9001:2000-TickIT Guide 5.0 has been established mainly in Europe as one of the well-known Quality Management Systems, in order to create a continuous software process improvement throughout software organizations that is mainly related to a certi¯cation process. This thesis is developed to mainly answer the question of how Extreme Programming and the standard ISO 9001:2000 with its interpretation for software development as TickIT Guide 5.0 can be used together, in order to have a continuous software process improvement with the agility to respond quickly to environment changes and satisfy the customer needs and expectations.

Social networking services are relatively new phenomena and they have attracted so much attention around themselves. These services have been seen by many organizations as a po-tential tool to facilitate knowledge sharing. However, very few have successfully adopted such services. Many problems which lead to failures arise when it comes to developing and implementing social networking services with the goal to facilitate knowledge sharing.The purpose of this thesis is to investigate the failure of one social networking service to satisfy the knowledge sharing needs of the organization that has developed and implement-ed it in-house.Interviews with three employees of the company were arranged. The interviews were done with time intervals in between. This gave us the opportunity to rearrange the questions that were going to be asked to the next interviewee. The interviews were really helpful and gave us a good insight of the problem with the development and implementation of the social networking service that the organization was facing. After the interviews were conducted, a questionnaire was elaborated and sent out to the employees in the organization.The results we came up with were really interesting. A table with failure factors for the so-cial networking service used in the organization was made and a model suggesting the steps an organization should follow for the successful development and implementation of a so-cial networking service that facilitates knowledge sharing internally was developed.We found out that the failure was not in the social networking service itself but in the way it was presented, positioned and communicated to the employees of the company. They never took the service seriously for its intended purpose which was knowledge sharing within the organization and that led to the cancelation of the project.

Web site usability is an important factor when creating and managing web sites, since it essentially determines whether or not the site is usable by its intended audience. As an attempt to simplify the process of achieving high usability for web sites, this thesis has explored the possibility of integrating usability guidelines with web content management systems. The overall aim was to determine if, and how, usability guidelines can be implemented in a web content management system to make it promote and deliver web site usability, and to find solutions that aid web site users in carrying out the basic tasks of finding, reading and understanding information on the web. To estimate the effectiveness of such solutions, the level of human dependency was considered when evaluating the solutions. This thesis has shown that it is possible to construct such solutions, and has found several for each of the basic user tasks of finding, reading and understanding information. Although some of the found solutions automatically improve a site's usability or actively promote site usability, the majority are still dependent on human efforts in order to promote usability. It was concluded that it is possible to integrate usability guidelines with a web content management system, but that web site usability still largely depends on human effort in order to be effective.

The help desk serves as the first support level for solving IT problems but sometimes they have their own problems. These problems can be linked to the lack of access to the right knowledge which could be solved by implementing knowledge management so that agents have all the knowledge they need available to them when they need it. There is statistical data available to confirm that, by implementing this knowledge management-centric approach, there is a significant improvement in throughput and reduced times spent on calls. Yet there seems to be that there is no research available to show us the cultural, process, resource and responsibility impact of knowledge management in this environment. This is the focus of this project and by creating a special knowledge management system prototype, for a working help desk, these aspects are analyzed. The results show a minimal culture barrier, more structured processes, better access to resources and increased responsibilities.

Buildings are responsible for a significant portion of energy consumption worldwide. Intelligent buildings have been devised as a potential solution, where energy consumption and building use are harmonised. At the heart of the intelligent building is the building energy management system (BEMS), the central platform which manages and coordinates all the building monitoring and control subsystems, such as heating and lighting loads. There is often a disconnect between the BEMS and the building it is installed in, leading to inefficient operation, due to incongruous commissioning of sensors and control systems. In these cases, the BEMS has a lack of knowledge of the building form and function, requiring further complex optimisation, to facilitate efficient all year round operation. Flawed BEMS configurations can then lead to ‘sick buildings’. Recently, building energy performance simulation (BEPS) has been viewed as a conceptual solution to assist in efficient building control. Building energy simulation models offer a virtual environment to test many scenarios of BEMS operation strategies and the ability to quickly evaluate their effects on energy consumption and occupant comfort. Challenges include having an accurate building model, but recent advances in building information modelling (BIM) offer the chance to leverage existing building data, which can be translated into a form understood by the building simulator. This study will address these challenges, by developing and integrating a BEMS, with a BIM for BEPS assisted predictive control, and assessing the outcome and potential of the integration.

Den ökade användningen av kunskap inom organisationer har utvecklat teorin inom Knowledge Management (KM). KM-processer utvecklas för större organisationer vilket skapar problem när dessa ska tillämpas inom SME (Small och medium Enterprises), som karaktäriseras av en brist på resurser och standardisering. Ytterligare problem uppstår inom konsultorganisationer när arbetet mot kunder prioriteras före arbete som bidrar till organisationsutveckling. Vår studie fokuserar därmed på konsult-SMEer och de utmaningar som dessa ställs inför inom KM. Abstrakt Genom en litteraturstudie identifierades tre problemområden när det gäller KM- processer inom dessa organisationer; kodifikation, organisatorisk struktur och skapande av kunskapsvänlig kultur. Inom varje problemområde finns det även ett antal utmaningar som organisationerna ställs inför. Dessa utmaningar studerades empiriskt hos två olika konsult-SMEer som arbetade inom IT. Den empiriska undersökningen bidrog med nya utmaningar som inte identifierades i litteraturen, dessa presenteras i diskussionen. I slutsatse / The increased use of knowledge within organizations has contributed to the development of Knowledge Management (KM). The processes of KM are developed for larger organizations. This creates problems when they are directly applied on a SME (Small and Medium Enterprises), which is characterized by a lack of resources and standardization. Additional problems arise within consulting organizations when work towards the customer is prioritized above organizational-development. This study focuses on consulting SMEs and the issues that arise through their KM- development. Abstract Through a literature-review we identified three problematic areas for KM-processes within consulting SMEs. The areas are codification, organizational structure and creation of a knowledge-friendly environment. Within each problematic area there were additional challenges that later was studied empirically. This study was done at two consulting-SMEs, both working within the field of IT. The empirical study contributed with new challenges that will be presented during the discussion
