Pełny tekst źródłaData privacy has been growing in importance in recent years, especially with the continuous increase of online activity. Researchers continuously study, design, and develop solutions aimed at enhancing users’ data privacy. The wicked problem of data privacy is the continuous challenge that defies straightforward solutions. Since there are many factors involved in data privacy, such as technological, legal, and human aspects, we can only aim at mitigating rather than solving this wicked problem. Our aim was to focus on human aspects for designing usable crypto-based privacy-enhancing solutions. In this thesis, we followed a user centered design method by using empirical qualitative means for investigating user’s perceptions and opinions of our solutions. Most of our work has focused on redactable signatures in the cloud context within an eHealth use-case. Redactable signatures are a privacy-enhancing scheme, which allow the removal of parts of a signed document by a specified party without invalidating the respective signature. Our results yielded key HCI considerations as well as guidelines of different means for supporting the design of future solutions.

Pełny tekst źródłaVårdrelaterade infektioner (VRI) är ett stort problem inom vården idag. För tidigt födda barn (prematurer) har problem att hålla sin kroppstemperatur inom normala gränser på grund av ökad värmeförlust. De behöver därför särskild vård som ges med hjälp av kuvöser, vilka bidrar till att minimera värmeförluster som sker via konvektion. Kuvösen som används inom neonatologin har identifierats som en av de bidragande faktorerna till VRI på grund av den varma och fuktiga miljön, vilken gör det lätt för mikroorganismer att föröka sig. För att bedöma i vilken utsträckning kuvösen är en faktor i spridningen av VRI har detta examensarbete genomfört ATP+AMP (total ATP) luminiscens-mätningar för att på så vis möjliggöra identifieringen av problemområden i kuvösen samt presentera lösningar till en del av dessa. ATP återfinns i både organisk materia och bakterier och är därför en bra indikator på ett problemområde på grund av att organisk materia agerar som näringsämne för bakterier. Enbart kuvösboxen tillhörande Giraffe® OmniBed® kuvösen testades i denna studie. Rengöringsprocessen av kuvösen observerades vid ett flertal tillfällen. Tillsammans med intervjuer resulterade detta i 29 förmodade problemområden belägna på eller inne i kuvösboxen. Dessa ställen mättes före och efter rengöring. Studien utfördes på neonatalavdelningen på Karolinska sjukhuset i Solna. Mätningar visade att delar som rengörs med en diskdesinfektor är mindre kontaminerade än de delar som rengörs manuellt. Flertalet områden på karossen blev mer kontaminerade efter rengöring vilket indikerade att utformningen av kuvösen behöver förbättras. Det var ofta tvålrester kvar på ytan av karossen, vilket resulterade i hämning av total ATP luminiscens-reaktion. Detta ledde till orealistiskt låga värden och att 45 av 570 mätningar exkluderades. Försiktighet bör iakttas vid användning av total ATP luminiscens-metoden, med Kikkomans LuciPac Pen, då sannolikheten för tvålrester ökar vid mätningar på karossen i kuvösen. En ångrengörare och flaskborste skulle kunna användas för att bättre nå och rengöra problemområden, såsom hålrum och runt värmeelementet i botten av chassit. Dessa redskap behöver dock utvärderas i framtida studier. Användningen av ångrengörare kan också minska eller eliminera användningen av ytdesinfektion, som orsakar röda irriterande ögon och yrsel hos städpersonal, om effektiviteten uppmätts hålla sjukhusets krav på renhet. Funktionaliteten hos kuvösen fanns vara utmärkt, men förbättringar behövs i utformningen av kuvösen för att möjligöra effektivare, lättare och bättre rengöring.

- Sorting: Arrange the alternatives into a few groups in preference order, so that the DM can manage them more effectively.
- Nominal classification: Assign alternatives to nominal groups structured by the DM, so that the number of groups, and the characteristics of each group, seem appropriate to the DM.
Sorting problems are studied extensively under three headings. Case-based distance sorting is carried out with Model I, which is optimized for use with cardinal criteria only, and Model II, which is designed for both cardinal and ordinal criteria; both sorting approaches are applied to a case study in Canadian municipal water usage analysis. Sorting in inventory management is studied using a case-based distance method designed for multiple criteria ABC analysis, and then applied to a case study involving hospital inventory management. Finally sorting is applied to bilateral negotiation using a case-based distance model to assist negotiators that is then demonstrated on a negotiation regarding the supply of bicycle components.
A new kind of decision analysis problem, called multiple criteria nominal classification (MCNC), is addressed. Traditional classification methods in MCDA focus on sorting alternatives into groups ordered by preference. MCNC is the classification of alternatives into nominal groups, structured by the DM, who specifies multiple characteristics for each group. The features, definitions and structures of MCNC are presented, emphasizing criterion and alternative flexibility. An analysis procedure is proposed to solve MCNC problems systematically and applied to a water resources planning problem.

Algumas ações do processo projetual se restringem aos pensamentos dos designers, gerando uma dificuldade para compreender o processo e torná-lo explícito. As pesquisas nessa área tentam transpor essas limitações, buscando perceber o modo como os designers resolvem os problemas para aprimorar a sua atuação. Esses problemas são caracterizados como mal-estruturados e podem ser vistos de diferentes perspectivas, gerando respostas distintas. O conceito de coevolução percebe a resolução de problemas de forma evolutiva: à medida que compreende-se um pouco mais o problema, as respostas tornam-se mais aprimoradas. Esta dissertação tem como objetivo geral compreender a coevolução do problema de design. Para isso, realizou-se uma pesquisa exploratória em um workshop em design, coletando as informações por meio de grupos focais e do registro, em vídeo, do processo realizado pelos participantes. A técnica utilizada para analisar as informações coletadas nos grupos focais e nos vídeos foi a análise de conteúdo, com algumas adaptações necessárias à pesquisa realizada. Na análise, percebeu-se que a coevolução é influenciada: 1) pela formulação inicial do problema que funciona como uma força motora, impulsionando o processo de resolução do problema; 2) pela forma como as equipes se articulam, levando-se em conta o modo como os integrantes desempenham diferentes papeis e estabelecem um ritmo de resolução do problema de acordo com experiências anteriores que trazem para o projeto; 3) pelos questionamentos em relação ao problema ou à solução, caracterizando-se como uma das estratégias utilizadas pelos designers para avançar no espaço-problema ou no espaço-solução. Concluiu-se, assim, que não só o espaço-problema e o espaço-solução se modificam no percurso do projeto de forma a provocar uma evolução mútua, mas os diversos fatores que envolvem o processo projetual também influenciam na coevolução do problema de design.
Some actions in the design process are restricted to the designers’ thoughts, what may cause some difficulties in understanding the process itself and making it explicit. Studies in this area attempt to overcome these limitations by looking into the way designers solve problems to improve their performance. These problems are usually characterized as ill-structured and can be seen from different perspectives, leading to distinct answers. The concept of co-evolution regards problem resolution in an evolutive manner: as the problem is better understood, the answers become more refined. The overall objective of this work is to understand the co-evolution of the design problem. In order to do this, an exploratory research was conducted within a design workshop, where data was collected by means of both focal groups and videos recording the participants’ process. The technique used to analyse all this data was Content Analysis, with some necessary adaptations to the context of the present research. In the analysis, it was possible to observe that co-evolution is influenced by: 1) the initial formulation of the problem that works as a driving force, boosting the problem resolution process; 2) the way the groups manage themselves, taking into consideration the manner in which different members play distinct roles and establish a problem resolution pace based on previous experiences they bring to the project; and 3) inquiries related to the problem or the solution, which can be regarded as one of the strategies used by designers to move forward into the problem space or the solution space. In conclusion, all these observations lead to the understanding that not only the problem space and the solution space modify themselves in the course of the project, triggering mutual evolution, but the diverse aspects involved in the design context also have some influence on the co-evolution of the design problem.

Pełny tekst źródłaO design de sistemas interativos é um processo complexo, iterativo e colaborativo, que requer diferentes conhecimentos para sua realização, e composto por diferentes atividades que se inter-relacionam na composição de um produto final. As informações produzidas durante cada atividade são de extrema relevância para a continuidade do processo e para a compreensão, explicação e manutenção do produto produzido. Estas informações devem estar relacionadas e integradas em um discurso claro e coerente, permitindo sua rastreabilidade e contemplando a proveniência e o contexto em que foram produzidas. Observa-se, entretanto, que as propostas de captura e modelagem do processo de design em IHC provêem uma visão fragmentada e/ou incompleta deste processo. Por esta razão, propõe-se aqui um modelo epistêmico, baseado em Design Rationale (DR), adequado ao registro e modelagem do design de sistemas interativos. Com base na revisão e análise das principais visões e propostas do processo de design, seus requisitos, modelos, notações, linguagens de suporte foi proposto o modelo epistêmico Ideia. O modelo tem como principal objetivo registrar e comunicar as atividades de design de forma coesa, oferecendo subsídios para a reflexão da equipe de design sobre as atividades do processo de design, bem como informações de proveniência para a rastreabilidade das informações. Para isso, o modelo propõe a integração dos insumos e produtos (e.g., requisitos, modelos, artefatos) das atividades de design, oferecendo uma ponte entre as atividades de análise (espaço de problema) e de design conceitual (espaço de solução) por meio do DR. O modelo foi implementado no protótipo Deprost e adotado no design de parte de um sistema colaborativo, o sistema WikiMapps, possibilitando avaliar a proposta através de um estudo de caso sobre seu desempenho quanto ao que é proposto.
The design of interactive systems is a complex, iterative and collaborative process, composed of different activities that are interrelated in the composition of a final product and requires different expertise to perform it. The information produced during each activity is very important for the continuity of the process and to understand, explain and maintain the product produced. This information must be related and integrated in a clear and coherent speech, allowing traceability and addressing the origin and the context in which they were produced. It is noted, however, that the proposed process catch and modeling in HCI design provide a fragmented and/or incomplete view of this process. For this reason, we propose an epistemic model, based on Design Rationale (DR), suitable for the recording and modeling of the design of interactive systems. Based on the review and analysis of the key views and proposals of the design process, their requirements, models, notations and support languages, the epistemic model Ideia has been proposed. The model has as its main goal to register and report design activities in a cohesive manner, offering support for the reflection of the design team about the activities of the design process as well as information sources for the traceability of information. For this, the model proposes the integration of inputs and outputs (e.g., requirements, models, artifacts) of the activities of analysis (problem space) and the conceptual design (solution space) DR. The model was implemented in the Deprost prototype and adopted in the design of part of the WikiMapps project, allowing us to evaluate the proposal in a real case study.

The present work aims to address the problem of fluid-structure interaction using a discontinuous Galerkin approach. Starting from the Navier-Stokes equations on a fixed domain, an arbitrary Lagrangian Eulerian (ALE) approach is used to derive the equations for the deforming domain. A geometric conservation law (GCL) is then introduced, which guarantees freestream preservation of the numerical scheme. The space discretization is performed using a discontinuous Galerkin method and time integration is performed using either an explicit four stage Runge-Kutta scheme or an implicit BDF2 scheme. The mapping parameters for the ALE formulation are then obtained using algorithms based on radial basis functions (RBF) or linear elasticity. These strategies are robust and can be applied to bodies with arbitrary shapes and undergoing arbitrary motions. The robustness and accuracy of the ALE scheme coupled with these mapping strategies is then demonstrated by solving some model problems. The ability of the scheme to handle complex flow problems is demonstrated by analyzing the low Reynolds number flow over an oscillating circular cylinder.

Pełny tekst źródłaThis thesis investigates the second-best toll pricing and capacity expansion problems when stated as mathematical programs with equilibrium constraints (MPEC). Three main questions are rised: First, whether conventional descent methods give sufficiently good solutions, or whether global solution methods are to prefer. Second, how the performance of the considered solution methods scale with network size. Third, how a discretized stochastic mathematical program with equilibrium constraints (SMPEC) formulation of a stochastic network design problem can be practically solved. An attempt to answer these questions is done through a series ofnumerical experiments.
The traffic system is modeled using the Wardrop’s principle for user behavior, separable cost functions of BPR- and TU71-type. Also elastic demand is considered for some problem instances.
Two already developed method approaches are considered: implicit programming and a cutting constraint algorithm. For the implicit programming approach, several methods—both local and global—are applied and for the traffic assignment problem an implementation of the disaggregate simplicial decomposition (DSD) method is used. Regarding the first question concerning local and global methods, our results don’t give a clear answer.
The results from numerical experiments of both approaches on networks of different sizes shows that the implicit programming approach has potential to solve large-scale problems, while the cutting constraint algorithm scales worse with network size.
Also for the stochastic extension of the network design problem, the numerical experiments indicate that implicit programming is a good approach to the problem.
Further, a number of theorems providing sufficient conditions for strong regularity of the traffic assignment solution mapping for OD connectors and BPR cost functions are given.

PROGRAMA DE SUPORTE À PÓS-GRADUAÇÃO DE INSTS. DE ENSINO
Atualmente mais da metade da população mundial mora em cidades. O deslocamento na região urbana, mediante a utilização de transporte público se dificulta devido ao planejamento deficiente das rotas e redes de transporte, longos tempos de viagem, aumento do custo das passagens, dos tempos de espera, etc. Como consequência, a busca de operações mais eficientes no sistema de transporte público urbano tem aumentado visando atender as necessidades de transporte de forma mais sustentável. Após a revisão da literatura relacionada ao problema de desenho de rede de transporte público urbano, foi escolhido o método proposto por Aquino, (1980), aplicável para redes de ônibus urbanos. Por médio da modernização do programa do método escolhido e as melhorias nele, o número de rotas que define a rede conectada diminuiu. O número de transbordos na rede foi minimizado até zera-lo com um menor conjunto de rotas. Análise de indicadores e de rentabilidade das rotas que minimizam o número de transbordo na rede, permite ao planejador ter uma visão geral do comportamento dessas rotas possibilitando tomar decisões mantendo os requerimentos iniciais e o objetivo de estudo. O programa do método desenvolvido, adaptado a uma linguagem moderna, Cmais mais, oferece, tanto ao meio acadêmico quanto ao profissional, uma ferramenta de fácil aplicação para dar solução ao Problema de Desenho de Rede de Transporte Público Urbano. Contribuindo potencialmente ao incremento da eficiência do processo de planejamento e, portanto, à redução de não conformidades do serviço de transporte resultando em economia dos custos para as empresas prestadoras deste serviço.
Nowadays, more than half of the world s population lives in cities. Displacement in the urban area through the use of public transportation is hampered by poor planning of transport routes and networks, long travel times, increased ticket costs and waiting times, etc. As a consequence, the search for more efficient operations in the urban public transport system has increased in order to meet the transport needs in a more sustainable way. After the literature review related to the urban public transport network design problem, the method proposed by Aquino (1980), applicable to urban bus networks, was chosen. By means of the program s modernization of the chosen method and the improvements in it, the number of routes defining the connected network has decreased. The overflow number on the network has been minimized to zero with a smaller set of routes. Analysis of indicators and profitability of the routes that minimize the number of transfer in the network, allows the planner to have an overview of the behavior of these routes allowing to make decisions keeping the initial requirements and the objective of study. The developed method program, adapted to a modern language, C plus plus, offers both an academic and a professional environment an easy application tool to solve the Urban Public Transport Network Design Problem. Potentially contributing to the increase of the efficiency of the planning process and, therefore, to the reduction of nonconformities of the transport service, resulting in cost savings for the companies that provide this service.

Pełny tekst źródłaNowadays in the aircraft industry, structural optimization problemscan be really complex and combine changes in choices of materials, stiffeners, orsizes/types of elements. In this work, it is proposed to solve large scale structural weightminimization problems with both categorical and continuous variables, subject to stressand displacements constraints. Three algorithms have been proposed. As a first attempt,an algorithm based on the branch and bound generic framework has been implemented.A specific formulation to compute lower bounds has been proposed. According to thenumerical tests, the algorithm returned the exact optima. However, the exponentialscalability of the computational cost with respect to the number of structural elementsprevents from an industrial application. The second algorithm relies on a bi-level formulationof the mixed categorical problem. The master full categorical problem consists ofminimizing a first order like approximation of the slave problem with respect to the categoricaldesign variables. The method offers a quasi-linear scaling of the computationalcost with respect to the number of elements and categorical values. Finally, in the thirdapproach the optimization problem is formulated as a bi-level mixed integer non-linearprogram with relaxable design variables. Numerical tests include an optimization casewith more than one hundred structural elements. Also, the computational cost scalingis quasi-independent from the number of available categorical values per element

Pełny tekst źródłaUnder det senaste decenniet har marknaden erbjudits en mängd olika typer av molntjänster och utvecklings-ramverk framtagna av ledande företag inom mjukvaruindustrin. Dessa tjänster har ofta använts för att lösa specifika uppgifter. Olika komponenterna som ingår i dessa specifika lösningar har med tiden utvecklats ändrats allteftersom de har mognat. Att integrera dessa komponenter för att lösa en helt ny uppgift tenderar därför att bli svårt på grund av deras instabila, inkompatibla och experimentella karaktär. Medan vissa teknikkomponenter kan fortsätta att utvecklas kan andra avstanna och utgå. Vi har närmat oss detta problemområde genom agil och iterativ utveckling samt användar-centrerad design-metod. En moln-baserad lösning som bland annat integrerat bleeding-edge teknikkomponenter har utvecklats och utvärderats med syfte att ge en icke-påträngande tekniskt support för gå-möten. De resultat som här presenteras och diskuteras baseras på interaktion med forskargruppen inom projektet "Med rörelse i tankarna", användarstudier och användartesteter i fält på olika arbetsplatser där den prototyp som utvecklats sökt motsvara användarnas utryckta förväntningar på tekniskt support för gångmöten. Vi diskuterar också prototypens egenskaper och vår motivation för val av metoder för att utveckla den. Slutligen diskuterar vi de utvecklingsutmaningar vi ställdes inför under vårt försök och om det är rimligt att integrera olika bleeding-edge komponenter för att lösa komplexa verkliga problem eller huruvida man hellre bör vänta på att dessa teknologier nått en stabilare mognadsgrad.

In the past, most public construction agencies in Taiwan manage construction projects in a conventional manner for preventing corruption. That is, a design-bid-build contracting method and a low-bid tendering method are often adopted for finding a contractor. Such a traditional apporach has caused numerous inefficiencies and disputes due to the misinterpretation of design, construction interterferences, and many other factors. After the Government Procurement Law has been enacted, a new approach that is based on the design/build (also called turnkey) contracting method and the most advantageous tendering method can be adopted by law. However, construction disputes remain even when the new approach is applied. Thus, this study aims to investigate the reasons and suggust solutions of these construction disputes by analyzing six design/build projects. These case projects were all related to the construction of new high-school facilities. According to these case studies, this work identifies six types of construction disputs. The lessons learned for each dispute are discussed. Overall, the findings of this study should be able to support public agencies in managing both design/build and design-bid-build projects.

Use of the Design-Build procurement foe public construction works can improve the defects by traditional procurement methods, such as overly long design periods, complex working interfaces, and awards resulting in unreasonably low price bids and poor quality work etc. Because of public sector often do not understand the Design-Build system in the implementation, or inadequate advance work, which led to problems of implementation, the performance not only generate a lot of controversy, also negative affecting on the implementation of the Design-Build system. For this reason, the study primary focus on public works for Design-Build project the present situation and effectiveness of the implementation, and the type of Design-Build dispute induction from compliance dispute case, analyze the causes of the dispute, discussion public sector for the crux of the problem, further discussion of contract changes, Order to be able reduce the authorities and the contractors shall cognitive differences when the contract changes, research appropriate manner of design review, comparison of the model Design-Build contract terms and the terms of FIDIC Silver Book, expectations related to improving views on the content of the Design-Build contract template as suggestion for future reference of agencies concerned.
