This thesis investigates the design of atria for daylighting in large scale buildings. Athree dimensional test building with a central atrium was constructed and various parameters of the atrium altered. The impact of these changes was studied through computer simulations of annual daylight distribution by implementing state of theart software. Daylight autonomy is simulated for an annual climate file for Stockholm, Sweden. In the thesis, notion is made of basic daylighting concepts, the importance of bringing daylight into buildings is argued, and the daylighting criteria of three environmental certification tools introduced. Furthermore, a detailed comparison is made on several well known daylight simulation tools. A newly developed, state of the art, daylight simulation tool called Honeybee, is used in the simulation process. The tool utilizes the calculation engines of wellknown daylight simulation software Radiance and Daysim, which apply backward ray-tracing to reach accurate results. Honeybee is coupled to the graphical algorithmeditor Grasshopper for Rhinoceros 3D, which allows for an efficient way of parametric modelling. The comparison of five different daylight simulation tools showed that Honeybee outweighs the capabilities of many of them by offering a wast range of simulation capabilities and also giving the user exceptional control of result data within multiple zones of the test building. The results of the daylight study have been compiled into a document which purpose is to serve as early stage design guidelines of atria for architects. Many factors have been shown through simulation to have a dramatic impact on daylighton an annual basis, and several suggestions have been made on how to maximize the quantity of daylight within buildings containing atria.

The relationship between narrative and game mechanics has been researched under terms such as ludonarrative dissonance, ludonarrative resonance and narrative mechanics. Yu-Gi-Oh! is a Trading Card Game which contains game mechanics that symbolically represents sections of the Arthurian legend. In this thesis the mechanics of specific Yu-Gi-Oh! cards were compared to the Arthurian legend. From this analysis were design guidelines derived, on how to represent a narrative with game mechanics. Game objects can be referenced by listing associated cards. The name of a mechanic can help in symbolically tell a narrative. The exclusion of a mechanic can also represent something. The conditions for a mechanic to be available is an area where narrative can be implemented. If a narrative mechanic is surrounded by many other mechanics, the symbolism can be “drowned out”. There is a balance between effective symbolism and a good game mechanic.

This research aims to make the first step in the direction of creating guidelines to use for building an instrument capable to collect information about citizens’ emotional reaction toward their city.Through the use of an existing mobile application meant to collect data about one’s own emotions I tried to evaluated the availability of people in sharing how they feel.Later on, based on the evaluations of this app, I created two subsequent analog prototypes that can be placed in urban spaces to collect people’s place related emotions. The devices have been used both inside the university and in open urban spaces in Malmö. Using the experiences made with these prototypes, concerning the availability of people in sharing their emotions about spaces, this thesis is used to develop guidelines and design opportunities for further development of interactive street furniture designed to collect place related emotions.

Das Ziel des ServFace Projektes ist es Endnutzern ohne umfangreiche IT-Kenntnisse das einfache Erstellen von servicebasierten Anwendungen zu ermöglichen. Dazu wird ein Kompositions- werkzeug mit dem Namen “ServFace Builder“ verwendet. Das Werkzeug erlaubt es Endnutzern, interaktive Anwendungen durch die Komposition von Service-Operationen zu erstellen. Dafür ist eine grafische Repräsentation der Service-Operationen durch UI-Fragmente notwendig. Die UI-Fragmente werden im ServFace-Umfeld als Frontends bezeichnet. In der vorliegenden Arbeit wird ein Konzept zur automatischen Visualisierung dieser Frontends vorgestellt. Um das Ergebnis der Visualisierung zu verbessern, nutzt der Visualisierungsprozess neben der Service-Beschreibung weitere Informationen in Form von Annotationen und Gestaltungsempfehlungen. Konkret werden die folgenden Aspekte in dieser Arbeit beschrieben: • Visualisierung von Frontends zur Repräsentation von Service-Operationen auf Basis von Service-Beschreibungen, Annotationen, Plattformspezifikationen und Gestaltungsempfehlungen unter der Maßgabe der Gebrauchstauglichkeit und Nutzbarkeit. • Integration der Frontends in die jeweils aktuelle Instanzen des gegebenen Anwendungsmodells. • Technische Umsetzung und Evaluation der entwickelten Konzepte / The aim of the ServFace Project is to enable users with limited IT skills to easily create service-based applications. In order to do so, a tool called "ServFace Builder" has been developed. This tool allows users to build a composite application by combining several service operations. An important part of the ServFace Builder is the graphical representation of those service operations through user interfaces. This thesis describes an approach to automatically generate user interfaces for service operations. To enhance the graphical representation, the user interface generation process of the ServFace Builder comprises annotations and design recommendations next to the common service descriptions to enhance the result of the generation process. This thesis discusses: • Graphical representation of service operations on the basis of service descriptions, annotations, plattform specifications and design recommendations. • Integration of the graphical representation into the actual instance of the given application model. • Implementation and evaluation of the presented concepts.

This paper investigates how audio monitoring systems should be designed, in the context of smart cities and in accordance with Swedish legislation. Audio monitoring for smart cities is promising and have previously shown great potential. However its opportunities are still relatively unexplored. ShotSpotter is one of several examples of audio monitoring in the context of smart cities. In the US only, the system has successfully been used to alert and locate shootings in over 90 cities. However, the technology is surrounded by controversies and there has been debate whether audio monitoring systems are compatible with law. Compatibility is critical since incompatibility could result in severe sanctions. Research related to this paper has been conducted according to the Design Science research strategy. The research resulted in design guidelines for audio monitoring systems, for law enforcement purposes, in accordance with Swedish law. The design guidelines are based upon existing audio monitoring systems, previous research and empirical data. The empirical data consists of 12 interviews with experts in law, phonetics and digital forensics. Additionally, the design guidelines have been evaluated by an expert in a criteria-based evaluation interview. Results of the research shows that it is, in fact, possible to design audio monitoring systems, in the context of smart cities, in accordance with Swedish legislation. The design guidelines can be applied in the development of audio monitoring systems with law enforcement purposes. With some modification, they can also be used for audio monitoring systems with other purposes. / Uppsatsen syftar till att undersöka hur ljudövervakningssystem inom ramen för smarta städer- konceptet bör utformas i enlighet med svensk lagstiftning. Ljudövervakning för smarta städer har visat på stor potential och ännu är dess möjligheter outforskade. ShotSpotter är ett av flera exempel på ljudövervakning inom ramen för smarta städer. Systemet har med framgång använts för att uppmärksamma och lokalisera skottlossningar i över 90 amerikanska städer. Det råder dock debatt huruvida ljudövervakningssystemet är kompatibelt med lagstiftning. Denna kompatibilitet är kritisk då det motsatta kan resultera i stränga påföljder och därmed utgöra direkta hinder för implementation. Forskning i relation till uppsatsen har genomförts inom ramen för forskningsstrategin Design Science. Forskningsprocessen har mynnat ut i designriktlinjer för hur ett ljudövervakningssystem med brottsbekämpande syfte bör utformas i enlighet med svensk lagstiftning. Designriktlinjerna baseras på befintliga ljudövervakningssystem, tidigare forskning och omfattande empiriskt underlag. Det empiriska underlaget utgörs av 12 intervjuer med olika typer av experter inom juridik, fonetik och IT- forensik. Designriktlinjerna har med framgång utvärderats i en kriteriebaserad expertintervju. Av forskningsresultatet att döma är det möjligt att utforma ljudövervakningssystem för smarta städer i enlighet med svensk lagstiftning. De framtagna designriktlinjerna kan användas vid utveckling av ljudövervakningssystem med brottsbekämpande syfte. Med viss modifikation kan de även användas för ljudövervakningssystem med andra syften.

The word revise means to reconsider or modify as with text. If we think of the suburban landscape as a text, the culture of each era left documentation of their values, policies and way of life in the form of transportation networks and other infrastructure, such as Main Streets, squares and public buildings. While evidence of most of the everyday life of individuals of every era gets erased by the following era, infrastructure investments of each era are adaptively reused and remain to tell the story. This thesis documents the adaptive reuse of these suburban frameworks and develops a proposition for the appropriate next layer to accommodate a new culture of inhabitants. Focusing on second generation suburbs, using Gwinnett County as a case study, this analysis identifies three problems of the current suburban situation: the problem of abandoned strips, a demographic shift, and the need for place. As new strip highways develop, old strips decline leaving abandoned shopping centers and declining property values. New development continues to move north and out of the county, and middle class residents, for which existing auto-oriented suburbs were created, move as well. A new, poorer, and more ethnically diverse population inherits the auto-oriented landscape left behind. This phenomenon is particularly concentrated along the southern portion of the Buford Highway corridor. Those with more money move closer to new development, while those with less money have less choice and are found near declining strips with fewer services, poorer quality housing and lower quality of life. Finally, county officials have expressed a desire for defining "the epicenter of Gwinnett." I believe that there is no one "center" of Gwinnett, but a series of places defined by memory, design or events. I propose to improve the situation of these three problems with a light rail line that connects existing places and creates new walkable, livable places to improve quality of life. This connective piece will serve as a social condenser in lieu of a center, provide links between polar populations, and reactivate declining strips while creating a sustainable infrastructural spine for future growth in the region.

L'intégration 3DVLSI, également connue sous le nom d'intégration monolithique ou séquentielle, est présentée et évaluée dans cette thèse comme une alternative à la réduction du nœud technologique des circuits logiques CMOS. L’avantage principal de cette technologie par rapport à l'intégration parallèle 3D, déjà existante, est l'alignement précis entre les niveaux, ce qui permet des contacts 3D réduits et plus proches. Un autre avantage, extrêmement favorable à l’approche 3DVLSI, est l’amélioration du placement et du routage par rapport aux circuits planaires, notamment parce qu’elle permet des interconnexions plus courtes et qu’elle offre a un degré de liberté supplémentaire dans la direction Z pour la conception. Par exemple, les fils les plus longs dans les circuits planaires peuvent ainsi être réduits grâce aux contacts 3DCO, en diminuant les éléments parasites d'interconnexion. Il est ainsi possible d’augmenter la vitesse du circuit et de réduire la puissance électrique. Dans ce contexte, la thèse a été divisée en deux parties. La première partie traite de l’évaluation de la Consommation, des Performances et de la Surface (CPS) et donne des recommandations pour la conception des circuits 3D. La deuxième partie traite la variabilité des circuits 3D en utilisant un modèle statistique unifié, et en proposant une approche pour la variabilité des circuits multi-niveaux. / 3DVLSI integration, also known as monolithic or sequential integration is presented and evaluated in this thesis as a potential contender to continue the scaling for CMOS logic circuits. The main advantage of this technology compared to the already existing 3D parallel integration is its high alignment among tiers, enabling small size and pitch with the inter-tier contacts (3DCO). Another great 3DVLSI feature is its improved capability to place and route circuits, compared to the planar approach: the interconnections can be shorter as the design has an additional degree of freedom in the Z direction. For instance, long wires in planar circuits can cut thanks to 3DCO contacts, lowering the interconnection parasitic elements and speeding up the circuit as well as reducing the power. In this framework, the thesis has been divided into two parts: the first part is dedicated to the evaluation of Performance, Power and Area (PPA) of 3D circuits and gives design guidelines. The second part treats the variability in 3D circuits by using a 3D unified statistical model and propose an approach for the multi-tier variability.

[pt] Hoje, os constantes avanços tecnológicos em interfaces digitais, e por consequência as interfaces gráficas do usuário, se fazem cada vez mais presentes na interação humano-máquina. Porém, num contexto em que sistemas inteligentes, a exemplo dos sistemas robóticos, já são uma realidade, ainda restam lacunas a serem preenchidas quando se pensa em integrar, com fluidez, robôs a trabalhos customizados e complexos. Esta pesquisa tem como foco a análise da usabilidade de interfaces de usuário específicas para a interação com robôs remotos também conhecidas como Robot User Interfaces (RUIs). Quando bem executadas, tais interfaces permitem aos operadores realizar remotamente tarefas em ambientes complexos. Para tanto, trabalha-se com a hipótese de que, se RUIs forem concebidas considerando as especificidades desses modelos de interação, as falhas operacionais serão reduzidas. O objetivo desta pesquisa foi avaliar diretrizes específicas para sistemas robóticos, compreendendo a relevância destas na usabilidade de interfaces. Para uma base teórica, foram levantados os modelos já existentes de interação com robôs e sistemas automatizados; e os princípios de design que se aplicam a estes modelos. Após a revisão bibliográfica, foram realizadas entrevistas contextuais com usuários de sistemas robóticos e testes de usabilidade, a fim de reproduzir, em interfaces com e sem diretrizes de RUIs, os processos de interação na realização de tarefas. Os resultados finais das técnicas aplicadas apontaram para a validade da hipótese - se interfaces específicas para sistemas robóticos forem concebidas considerando as especificidades dos modelos de interação humano-robô, as falhas operacionais na interação serão reduzidas - à medida que os sistemas desenvolvidos com interfaces específicas ao contexto de interação com robôs proporcionaram uma melhor usabilidade e mitigaram a ocorrência de uma série de possíveis falhas humanas. / [en] Nowadays, the constant technological advances, and consequently the graphical user interfaces, have become more and more present in the humanmachine interaction. However, in a context where intelligent systems, such as robotic systems, are already a reality, there are still gaps to be filled when we think about integrating robots with custom and complex activities. This research aims on the analysis of Robot User Interfaces (RUIs) usability. When well executed, such interfaces allow operators to remotely perform tasks in complex environments. To that intent, our hypothesis is that, if RUIs are conceived considering the specificities of these interaction models, operational failures will be reduced. The main goal of this research was to evaluate specific guidelines for robotic systems, understanding their relevance in usability. For a theoretical basis, the existing models of interaction with robots and autonomous systems were raised; as well as the design principles that apply to these models. After a bibliographic review, we conducted contextual interviews with users of robotic systems, and usability tests to reproduce, in interfaces with and without RUI guidelines, the interaction processes in the task completion. The final results of the applied techniques proved the validity of the hypothesis, as the systems developed with interfaces specific to the interaction with robots provided better usability and mitigated the occurrence of array of human faults.

The working situation of fighter pilots is often very challenging. The pilots are requested to perform their tasks and make decisions in situations characterised by time-pressure, huge amounts of data and high workload, knowing that wrong decisions might result in fatal consequences. To aid the pilots, several automatic support systems have been implemented in modern fighter aircraft and will continue to be implemented in pace with technological advancements and new demands posed on the pilots. For example, innovations within the information fusion (IF) domain have made it possible to fuse large amounts of data, stemming from different sensors, databases etc., to create a better foundation for making decisions and act than would have been possible if the information sources had been used separately. However, there are both positive and negative effects of automation, such as decreased workload and improved situation awareness on the one hand, but skill degradation and complacent behaviour on the other. To avoid the possible negative consequences of automation, while at the same time ameliorating the positive ones, a human-centred automation (HCA) approach to system design has been proposed as a way of optimizing the collaboration between the human and the machine. As a design approach, HCA stresses the importance of a cooperative human-machine relationship, where the operator is kept in the automation loop. However, how to introduce HCA within the fighter aircraft domain as well as its implications for the interface and automation design of support systems within the field has not been investigated. This thesis investigates the implications of introducing HCA into the fighter aircraft domain. Through literature surveys and empirical investigations, general and domain specific HCA guidelines have been identified. These advocate, for example, that an indication of the reliability of the information and the recommendations provided by the different aircraft support systems must be given as well as that support for appropriate updates of the pilots’ individual and team awareness of the situation must be provided. A demonstrator, mirroring some of the identified guidelines, has been implemented and used to evaluate the guidelines together with system developers within the domain. The evaluation indicated that system developers of modern fighter aircraft implicitly incorporate many of the identified HCA guidelines when designing. However, the evaluation further revealed that to explicitly incorporate these guidelines into the development approach, preferably through the development of a domain specific style guide, would aid the system developers design automated support systems that provide appropriate support for the pilots. The results presented in this thesis are expected to aid developers of modern fighter aircraft support systems by incorporating HCA into the traditional simulator-based design (SBD) approach. This approach is frequently used within the field and stresses early and frequent user-involvement when designing, in which complementary HCA evaluations could be performed to further improve the support systems implemented from an automation perspective. Furthermore, it is expected that the results presented in this thesis will contribute to the research regarding how to incorporate the human operator in the information fusion processes, which has been recognised as a research gap within the IF field. Thus, a further contribution of this thesis is the suggestion of how the HCA development approach could be of aid when improving the interaction between the operator and the automated fusion system. / Arbetssituationen för stridspiloter är ofta mycket utmanande. Piloterna måste utföra sina uppgifter och fatta beslut i stressiga situationer med stora informationsmängder och hög arbetsbörda, samtidigt som val av fel beslut kan leda till allvarliga konsekvenser. För att hjälpa piloterna har flera automatiska stödsystem implementerats i moderna stridsflygplan. Denna trend kommer att fortsätta i takt med nya tekniska framgångar och nya krav som ställs på piloterna. Forskning inom informationsfusion (IF) har bland annat gjort det möjligt att fusionera stora mängder data som härstammar från olika sensorer, databaser m.m. för att på så sätt skapa en bättre grund för att fatta beslut och agera än vad som hade varit möjligt om informationskällorna hade använts separat. Dock har både positiva och negativa effekter av automatisering rapporterats, såsom minskad arbetsbörda och förbättrad situationsuppfattning men även försämrad pilotprestation till följd av att de automatiska systemens prestanda inte övervakas. För att undvika negativa effekter av automation samtidigt som de positiva effekterna stärks har den så kallade människo centrerade automationen (HCA) lyfts fram som en möjlig väg att designa system där samverkan mellan automationen och den mänskliga operatören optimeras. Som en designapproach fokuserar HCA på viken av en samverkande människamaskin relation, där operatören hålls kvar i automatiseringsloopen. Men hur HCA kan introduceras inom stridsflygdomänen och dess implikationer för gränssnitts- och automationsdesign av stödsystem inom domänen har inte undersökts. Denna licentiatavhandling undersöker möjliga implikationer av att introducera HCA inom stridsflygdomänen. Genom litteraturundersökningar och empiriska studier har generalla och domänspecifika HCA riktlinjer identifierats, såsom att piloterna måste erbjudas en indikation angående tillförlitligheten hos den information och de rekommendationer som de olika implementerade stödsystemen i flygplanet har genererat, samt att stöd för att uppdatera piloternas individuella och gemensamma uppfattning av situationen måste ges. En demonstrator, som återspeglar några av de identifierade HCA riktlinjerna, har implementerats och använts för att utvärdera riktlinjerna tillsammans med systemutvecklare inom domänen. Denna utvärdering påvisade att systemutvecklare inom stridsflygdomänen implicit använder sig av många av de identifierade HCA riktlinjerna under designprocessen, men att explicit inkludera dessa i en domänspecifik design guide skulle kunna hjälpa dem att designa automatiska system som erbjuder lämpligt stöd för piloterna. De resultat som presenteras i denna licentiatavhandling förväntas kunna hjälpa utvecklare av moderna stridsflygsystem genom att inkludera HCA i den traditionella simulator-baserade designapproachen (SBD). Denna approach används flitigt inom området och fokuserar på tidigt och återkommande användardeltagande vid designarbetet, där komplementära HCA utvärderingar skulle kunna genomföras för att förbättra de stödsystem som implementeras från ett automationsperspektiv. Det förväntas även att de resultat som presenteras i denna avhandling kommer att bidra till forskningen kring hur operatörer kan påverka fusionsprocessen, vilket har identifierats som ett område där mer forskning behövs inom IF området. Ytterligare ett bidrag av denna avhandling är därför det förslag som ges på hur HCA utvecklingsprocessen skulle kunna användas för att förbättra interaktionen mellan operatören och det automatiska fusionssystemet.

The performance of building envelopes and roofing systems significantly depends on accurate knowledge of wind loads and the response of envelope components under realistic wind conditions. Wind tunnel testing is a well-established practice to determine wind loads on structures. For small structures much larger model scales are needed than for large structures, to maintain modeling accuracy and minimize Reynolds number effects. In these circumstances the ability to obtain a large enough turbulence integral scale is usually compromised by the limited dimensions of the wind tunnel meaning that it is not possible to simulate the low frequency end of the turbulence spectrum. Such flows are called flows with Partial Turbulence Simulation. In this dissertation, the test procedure and scaling requirements for tests in partial turbulence simulation are discussed. A theoretical method is proposed for including the effects of low-frequency turbulences in the post-test analysis. In this theory the turbulence spectrum is divided into two distinct statistical processes, one at high frequencies which can be simulated in the wind tunnel, and one at low frequencies which can be treated in a quasi-steady manner. The joint probability of load resulting from the two processes is derived from which full-scale equivalent peak pressure coefficients can be obtained. The efficacy of the method is proved by comparing predicted data derived from tests on large-scale models of the Silsoe Cube and Texas-Tech University buildings in Wall of Wind facility at Florida International University with the available full-scale data. For multi-layer building envelopes such as rain-screen walls, roof pavers, and vented energy efficient walls not only peak wind loads but also their spatial gradients are important. Wind permeable roof claddings like roof pavers are not well dealt with in many existing building codes and standards. Large-scale experiments were carried out to investigate the wind loading on concrete pavers including wind blow-off tests and pressure measurements. Simplified guidelines were developed for design of loose-laid roof pavers against wind uplift. The guidelines are formatted so that use can be made of the existing information in codes and standards such as ASCE 7-10 on pressure coefficients on components and cladding.
