Full textAbstract:
In urban conditions architecture often loses a connection with the surrounding context and viewers through inappropriate scale, design orientation and the misuse of light during the day and night. In areas of density, perception is everything.
This exploration seeks to express architecture as a language of light and transparency by emphasizing a long linear connection with the ground plane and surrounding city. This creates horizontal bands of space that emit and receive various forms of light. The goal of this thesis is to portray itself as a glowing beacon of attraction while simultaneously displaying its inner workings.Master of Architecture

Uma das principais preocupações para construir a próxima geração de sistemas PAD é o consumo de energia. Para quebrar a barreira de exascale a comunidade científica precisa investigar alternativas que possam lidar com o problema de consumo de energia. Sistemas PAD atuais não se preocupam com energia e já consomem GigaWatts. Requisitos de consumo de energia restringirão fortemente sistemas futuros. Nesse contexto processadores de alta potência abrem espaço para novas arquiteturas. Duas arquiteturas surgem no contexto de PAD. A primeira arquitetura são as unidades de processamento gráfico (GPU), GPUs possuem vários núcleos de processamento, suportando milhares de threads simultâneas, se adaptando bem a aplicações massivamente paralelas. Hoje alguns dos melhores sistemas PAD possuem GPUs que demonstram um alto desempenho por um baixo consumo de energia para várias aplicações paralelas. A segunda arquitetura são os processadores de baixo consumo, processadores ARM estão melhorando seu desempenho e mantendo o menor consumo de energia possível. Como exemplo desse ganho, projetos como Mont-Blanc apostam no uso de ARM para construir um sistema PAD energeticamente eficiente. Este trabalho visa verificar o potencial dessas arquiteturas emergentes. Avaliamos essas arquiteturas e comparamos com a arquitetura mais comum encontrada nos sistemas PAD atuais. O principal objetivo é analisar o consumo de energia e o desempenho dessas arquiteturas no contexto de sistemas PAD. Portanto, benchmarks heterogêneos foram executados em todas as arquiteturas. Os resultados mostram que a arquitetura de GPU foi a mais rápida e a melhor em termos de consumo de energia. GPU foi pelo menos 5 vezes mais rápida e consumiu 18 vezes menos energia considerando todos os benchmarks testados. Também observamos que processadores de alta potência foram mais rápidos e consumiram menos energia, para tarefas com uma carga de trabalho leve, do que comparado com processadores de baixo consumo. Entretanto, para tarefas com carga de trabalho leve processadores de baixo consumo apresentaram um consumo de energia melhor. Concluímos que sistemas heterogêneos combinando GPUs e processadores de baixo consumo podem ser uma solução interessante para alcançar um eficiência energética superior. Apesar de processadores de baixo consumo apresentarem um pior consumo de energia para cargas de trabalho pesadas. O consumo de energia extremamente baixo durante o processamento é inferior ao consumo ocioso das demais arquiteturas. Portanto, combinando processadores de baixo consumo para gerenciar GPUs pode resultar em uma eficiência energética superior a sistemas que combinam processadores de alta potência com GPUs.One of the main concerns to build the new generation of High Performance Computing (HPC) systems is energy consumption. To break the exascale barrier, the scientific community needs to investigate alternatives that cope with energy consumption. Current HPC systems are power hungry and are already consuming Megawatts of energy. Future exascale systems will be strongly constrained by their energy consumption requirements. Therefore, general purpose high power processors could be replaced by new architectures in HPC design. Two architectures emerge in the HPC context. The first architecture uses Graphic Processing Units (GPU). GPUs have many processing cores, supporting simultaneous execution of thousands of threads, adapting well to massively parallel applications. Today, top ranked HPC systems feature many GPUs, which present high processing speed at low energy consumption budget with various parallel applications. The second architecture uses Low Power Processors, such as ARM processors. They are improving the performance, while still aiming to keep the power consumption as low as possible. As an example of this performance gain, projects like Mont-Blanc bet on ARM to build energy efficient HPC systems. This work aims to verify the potential of these emerging architectures. We evaluate these architectures and compare them to the current most common HPC architecture, high power processors such as Intel. The main goal is to analyze the energy consumption and performance of these architectures in the HPC context. Therefore, heterogeneous HPC benchmarks were executed in the architectures. The results show that the GPU architecture is the fastest and the best in terms of energy efficiency. GPUs were at least 5 times faster while consuming 18 times less energy for all tested benchmarks. We also observed that high power processors are faster than low power processors and consume less energy for heavy-weight workloads. However, for light-weight workloads, low power processors presented a better energy efficiency. We conclude that heterogeneous systems combining GPUs and low power processors can be an interesting solution to achieve greater energy efficiency, although low power processors presented a worse energy efficiency for HPC workloads. Their extremely low power consumption during the processing of an application is less than the idle power of the other architectures. Therefore, combining low power processors with GPUs could result in an overall energy efficiency greater than high power processors combined with GPUs.

Full textAbstract:
With the rising costs of large scale distributed systems many researchers have began looking at utilizing low power architectures for clusters. In this paper, we describe our Astro cluster, which consists of 46 NVIDIA Jetson TK1 nodes each equipped with an ARM Cortex A15 CPU, 192 core Kepler GPU, 2 GB of RAM, and 16 GB of flash storage. The cluster has a number of advantages when compared to conventional clusters including lower power usage, ambient cooling, shared memory between the CPU and GPU, and affordability. The cluster is built using commodity hardware and can be setup for relatively low costs while providing up to 190 single precision GFLOPS of computing power per node due to its combined GPU/CPU architecture. The cluster currently uses one 48-port Gigabit Ethernet switch and runs Linux for Tegra, a modified version of Ubuntu provided by NVIDIA as its operating system. Common file systems such as PVFS, Ceph, and NFS are supported by the cluster and benchmarks such as HPL, LAPACK, and LAMMPS are used to evaluate the system. At peak performance, the cluster is able to produce 328 GFLOPS of double precision and a peak of 810W using the LINPACK benchmark placing the cluster at 324th place on the Green500. Single precision benchmarks result in a peak performance of 6800 GFLOPs. The Astro cluster aims to be a proof-of-concept for future low power clusters that utilize a similar architecture. The cluster is installed with many of the same applications used by top supercomputers and is validated using the several standard supercomputing benchmarks. We show that with the rise of low-power CPUs and GPUs, and the need for lower server costs, this cluster provides insight into how ARM and CPU-GPU hybrid chips will perform in high-performance computing.

Full textAbstract:
It is important for compilers to generate executable code that is as small as possible, particularly when generating code for embedded systems. One method of reducing code size is to use instruction set architectures (ISAs) that support combining multiple operations into single operations. The ARM ISA allows for combining multiple memory operations to contiguous memory addresses into a single operation. The LLVM compiler contains a specific memory optimization to perform this combining of memory operations, called ARMLoadStoreOpt. This optimization, however, relies on another optimization (ARMPreAllocLoadStoreOpt) to move eligible memory operations into proximity in order to perform properly. This mover optimization occurs before register allocation, while ARMLoadStoreOpt occurs after register allocation. This thesis implements a similar mover optimization (called MagnetPass) after register allocation is performed, and compares this implementation with the existing optimization. While in most cases the two optimizations provide comparable results, our implementation in its current state requires some improvements before it will be a viable alternative to the existing optimization. Specifically, the algorithm will need to be modified to reduce computational complexity, and our implementation will need to take care not to interfere with other LLVM optimizations.

Os veículos submarinos não tripulados tem uma importância crescente devido à sua flexibilidade e baixo custo. Devido à sua complexidade intrínseca, eles requerem diversas competências diferentes para serem desenvolvidos e permitem realizar pesquisas em vários campos do conhecimento. No contexto de uma universidade, que possui pessoal heterogêneo e de alta rotatividade, faz-se mister adotar uma organização que permita que os esforços de cada aluno possam ser reusados pelos outros, de modo as atividades de pesquisa possam avançar com pouca perda de tempo e retrabalho. Tal necessidade pode ser respondida pela aplicação de conceitos da engenharia de sistemas, tais como modularidade, separação formal entre soluções tecnológicas e necessidades, classificação funcional, critérios para escolha do método de desenvolvimento, uso de referencial normativo técnico, plano tecnológico, integração, verificação e validação e gerenciamento de configurações. Este trabalho se limita a desenvolver uma arquitetura de controle, observando os conceitos de engenharia de sistemas, aplicada a um AUV. É feita uma comparação com outras arquiteturas similares do estado da arte e mostram-se resultados de testes em piscina para esta arquitetura. É mostrado também que foi possível estabelecer a continuidade do desenvolvimento por outros alunos, validando a utilidade da metodologia. Conclui-se que, para aumentar a eficiência da pesquisa universitária, é necessário observar aspectos gerenciais e institucionais além dos aspectos técnicos ao conceber soluções técnicas.The unmanned underwater vehicles have a growing position due to their flexibility and low cost. Due to their inherent complexity, they require many different skills to be developed and they allow conducting research in various fields of knowledge. In the context of a university, which has heterogeneous staff and high turnover, there is the need of adopting an organization that allows the efforts of each student be reused by others, so research activities can proceed with little loss of time and rework. This need can be answered by the application of system engineering concepts such as modularity, formal separation between technology solutions and needs, functional classification, criteria for the choice of development method, use of technical reference standard, technological plan, integration, verification and validation and configuration management. This work is limited to development of a control architecture, observing the concepts of systems engineering, applied to an AUV. A comparison is made with other similar architectures in the state of the art and shows up test results in the pool for this architecture. It is also shown that it was possible to keep the development by other students, validating the utility of the methodology. It is concluded that in order to increase the efficiency of university research, it must be observed managerial and institutional aspects beyond the technical aspects when designing technical solutions.

Full textAbstract:
Cette thèse a pour objet la conception d'un hyperviseur logiciel sécurisé, à vocation de certification. Les plus hauts niveaux de certification requièrent l'usage de méthodes formelles, permettant de démontrer la validité d'un produit par rapport à une spécification à l'aide de la logique mathématique. Le matériel prouvé n'existant pas, les mécanismes d'hypervision sont implémentés en logiciel. Cela contribue à réduire la base de confiance, et donc la quantité de modélisation et de preuve à produire. En outre, cela rend possible la virtualisation de systèmes sur des plateformes qui ne sont pas dotées d'instructions de virtualisation. Les principaux challenges sont l'analyse du jeu d'instruction qui, malgré l'existence de documentation, comporte des ambiguïtés, des particularités dépendantes de l'implémentation et des comportements non définis. Puis, l'identification des intensions d'un système invité étant donné un flot d'instructions discret afin de rester en interposition avec le matériel sous-jacent. Pour ce faire, le code machine de l'invité est analysé et les instructions menaçant l'intégrité ou la confidentialité du système sont remplacées par des trapes logicielles, provoquant une analyse du contexte afin d'autoriser ou non leur exécution. Reposant sur l'existence d'un CPU et d'une MMU prouvés, seul du code privilégié est susceptible d'outrepasser les droits d'accès configurés par l'hyperviseur. Il n'est donc pas nécessaire d'hyperviser le code non privilégié. Les micro-noyau, généralement choisis pour leur légèreté, ont donc un second avantage : ils réduisent au minimum le surcoût de l’hypervisionThis thesis presents the design of a secured, software based hypervisor for certification purposes. The highest levels of certification require formal methods, which demonstrate the correctness of a product with regard to its specification using mathematical logic. Proven hardware is not available off-the-shelf. In order to reduce the Trusted Computing Base (TCB) and hence, the amount of specification and proofs to produce, virtualization mechanism are software-made. In addition, this enables virtualization on platforms which do not have virtualization-enabled hardware. The challenge for achieving this goal is twofold. On one hand, despite an existing documentation, the instruction set to be analysed has tedious corner cases, implementation-dependant behaviour or even worse, undefined behaviour. On the other hand to infer the system behaviors has to be infered given a discrete instruction flow, in order to remain interposed between the guest and the underlying hardware. For achieving this, the guest's machine code is analysed, and sensitive instructions (which threaten confidentiality or integrity) are replaced by traps, which enable arbitration given the actual guest context. Relying on hypothetically proven processor and memory management unit, only privileged code may bypass the configuration setup by the hypervisor and access the hardware. Thus, analysing unprivileged code is worthless in this case. Micro-kernel design which tends to offload most of the code in userspace, are suitable here. Using that paradigm reduces the overhead induced by certified virtualization

Full textAbstract:
Nowadays, network processors are an integral part of information technology. With the deployment of 5G network ramping up around the world, numerous new devices are going to take advantage of their processing power and programming flexibility. Contemporary information technology providers of today such as Ericsson, spend a great amount of financial resources on licensing deals to use processors with proprietary instruction set architecture designs from companies like Arm holdings. There is a new non-proprietary instruction set architecture technology being developed known as Risc-V. There are many open source processors based on Risc-V architecture, but it is still unclear how well an open-source Risc-V processor performs network packet processing tasks compared to an Arm-based processor. The main purpose of this thesis is to design a test model simulating and evaluating how well an open-source Risc-V processor performs packet processing compared to an Arm Cortex M7 processor. This was done by designing a C code simulating some key packet processing functions processing 50 randomly generated 72 bytes data packets. The following functions were tested: framing, parsing, pattern matching, and classification. The code was ported and executed in both an Arm Cortex M7 processor and an emulated open source Risc-V processor. A working packet processing test code was built, evaluated on an Arm Cortex M7 processor. Three different open-source Risc-V processors were tested, Arianne, SweRV core, and Rocket-chip. The execution time of both cases was analyzed and compared. The execution time of the test code on Arm was 67, 5 ns. Based on the results, it can be argued that open source Risc-V processor tools are not fully reliable yet and ready to be used for packet processing applications. Further evaluation should be performed on this topic, with a more in-depth look at the SweRV core processor, at physical open-source Risc-V hardware instead of emulators.Nätverksprocessorer är en viktig byggsten av informationsteknik idag. I takt med att 5G nätverk byggs ut runt om i världen, många fler enheter kommer att kunna ta del av deras kraftfulla prestanda och programerings flexibilitet. Informationsteknik företag som Ericsson, spenderarmycket ekonomiska resurser på licenser för att kunna använda proprietära instruktionsuppsättnings arkitektur teknik baserade processorer från ARM holdings. Det är väldigt kostam att fortsätta köpa licenser då dessa arkitekturer är en byggsten till designen av många processorer och andra komponenter. Idag finns det en lovande ny processor instruktionsuppsättnings arkitektur teknik som inte är licensierad så kallad Risc-V. Tack vare Risc-V har många propietära och öppen källkod processor utvecklats idag. Det finns dock väldigt lite information kring hur bra de presterar i nätverksapplikationer är känt idag. Kan en öppen-källkod Risc-V processor utföra nätverks databehandling funktioner lika bra som en proprietär Arm Cortex M7 processor? Huvudsyftet med detta arbete är att bygga en test model som undersöker hur väl en öppen-källkod Risc-V baserad processor utför databehandlings operationer av nätverk datapacket jämfört med en Arm Cortex M7 processor. Detta har utförts genom att ta fram en C programmeringskod som simulerar en mottagning och behandling av 72 bytes datapaket. De följande funktionerna testades, inramning, parsning, mönster matchning och klassificering. Koden kompilerades och testades i både en Arm Cortex M7 processor och 3 olika emulerade öppen källkod Risc-V processorer, Arianne, SweRV core och Rocket-chip. Efter att ha testat några öppen källkod Risc-V processorer och använt test koden i en ArmCortex M7 processor, kan det hävdas att öppen-källkod Risc-V processor verktygen inte är tillräckligt pålitliga än. Denna rapport tyder på att öppen-källkod Risc-V emulatorer och verktygen behöver utvecklas mer för att användas i nätverks applikationer. Det finns ett behov av ytterligare undersökning inom detta ämne i framtiden. Exempelvis, en djupare undersökning av SweRV core processor, eller en öppen-källkod Risc-V byggd hårdvara krävs.

Full textAbstract:
The Internet of Things (IoT) has seen a huge growth spurt in the last few years which has resulted in the need for more standardised IoT technology. Because of this, numerous IoT platforms have sprung up that offer a variety of features and use different technologies which may not necessarily be compliant with each other or with other technologies. Companies that wish to enter theIoT market are in constant need to find the most suitable IoT platform for their business and have a certain set of requirements that need to be fulfilled by the IoT platforms in order for the application to be fully functional. The problem that this thesis project is trying to address is a standardised procedure for selecting the IoT platforms. The project aims to suggest a list of requirements derived from the available IoT architecture models, that must be followed by IoT applications in general, and a subset of these requirements may be specified by the companies as essentials for their application. This thesis project also aims at development of a Web platform to automate this process, by listing the requirements on this website and allowing companies to input their choices,and accordingly show them the list of IoT platforms that comply with their input requirements. A simple Weighted Sum Model is used to rank the search result in order to prioritise the IoT platforms in order of the features that they provide. This thesis project also infers the best IoT architectural model available based on a comparative study of three major IoT architectures with respect to the requirements proposed. Hence the project concludes that this Web platform will ease the process of searching for the right IoT platform andthe companies can therefore make an informed decision about the kind of IoT platform that they should use, thereby reducing their time spent on market research and hence their time-to-market.

Full textAbstract:
Accurate virtual platforms allow for crucial, early, and inexpensive assessments about the viability and hardware constraints of software/hardware applications. The growth of multicore architectures in both number of cores and relevance in the industry, in turn, demands the emergence of faster and more efficient virtual platforms to make the benefits of single core simulation and emulation available to their multicore successors whilst maintaining accuracy, development costs, time, and efficiency at acceptable levels. The goal of this thesis is to find optimal virtual platforms to perform hardware design space exploration for multi-core architectures running filtering functions, particularly, a discrete signal filtering Matlab algorithm used for oil surveying applications running on an ARM Cortex-A53 quadcore CPU. In addition to the filtering algorithm, the PARSEC benchmark suite was also used to test platform compliance under workloads with diverse characteristics. Upon reviewing multiple virtual platforms, the gem5 simulator and the QEMU emulator were chosen to be tested due to their ubiquitousness, prominence and flexibility. A Raspberry Pi Model B was used as reference to measure how closely these tools can model a commonly used embedded platform. The results show that each of the virtual platforms is best suited for different scenarios. The QEMU emulator with KVM support yielded the best performance, albeit requiring access to a host with the same architecture as the target, and not guaranteeing timing accuracy. The most accurate setup was the gem5 simulator using a simplified cache system and an Out-of-Order detailed ARM CPU model.

Full textAbstract:
Digital Signal Processing(DSP) algorithms are widely implemented in real time systems.In fields such as digital music technology, many of these said algorithms areimplemented, often in combination, to achieve the desired functionality. When itcomes to implementation, DSP algorithms are performance critical as they havetight deadlines. In this thesis, performance optimization using Single InstructionMultiple Data(SIMD) vectorization technique is performed on the ARM Cortex-A15 architecture for six commonly used DSP algorithms; Gain, Mix, Gain and Mix,Complex Number Multiplication, Envelope Detection and Cascaded IIR Filter. Toensure optimal performance, the instructions should be scheduled with minimalpipeline stalls. This requires execution time to be measured with fine time granularity.First, a technique of accurately measuring the execution time using thecycle counter of the processor’s Performance Management Unit(PMU) along withsynchronization barriers is developed. It was found that the execution time measuredby using the operating system calls have high variations and very low timegranularity, whereas the cycle counter method was accurate and produced reliableresults. The cost associated with the cycle counter method is 75 clock cycles. Usingthis technique, the contribution by each SIMD instruction towards the executiontime is measured and is used to schedule the instructions. This thesis also presentsa guideline on how to schedule instructions which have data dependencies usingthe cycle counter timing execution time measurement technique, to ensure that thepipeline stalls are minimized. The algorithms are also modified, if needed, to favorvectorization and are implemented using ARM architecture specific SIMD instructions.These implementations are then compared to that which are automaticallyproduced by the compiler’s auto-vectorization feature. The execution times of theSIMD implementations was much lower compared to that produced by the compilerand the speedup ranged from 2.47 to 5.11. Also, the performance increaseis significant when the instructions are scheduled in an optimal way. This thesisconcludes that the auto-vectorized code does poorly for complex algorithms andproduces code with a lot of data dependencies causing pipeline stalls, even with fulloptimizations enabled. Using the guidelines presented in this thesis for schedulingthe instructions, the performance of the DSP algorithms have significant improvementscompared to their auto-vectorized counterparts.Digitala signalbehandlingsalgoritmer(DSP) implementeras ofta i realtidssystem. Inomfält som exempelvis digital musikteknik används dessa algoritmer, ofta i olika kombinationer,för att ge önskad funktionalitet. Implementationen av DSP-algoritmerär prestandakritisk eftersom systemen ofta har små tidsmarginaler. I det härexamensarbetet genomförs prestandaoptimering med Single Instruction MultipleData(SIMD)-vektorisering på en ARM A15-arkitektur för 6 vanliga DSP-algoritmer;volym, mix, volym och mix, multiplikation av komplexa tal, amplituddetektering,och seriekopplade IIR-filter. Maximal optimering av algoritmerna kräver ocksåatt antalet pipeline stalls i processorn minimeras. För att kunna observera dettakrävs att exekveringstiden kan mätas med hög tidsupplösning. I det här examensarbeteutvecklas först en teknik för att mäta exekveringstiden med hjälp aven klockcykelräknare i processorns Performance Management Unit(PMU) tillsammansmed synkroniseringsbarriärer. Tidsmätning med hjälp av operativsystemsfunktionervisade sig ha sämre noggrannhet och tidsupplösning än metoden medatt räkna klockcykler, som gav tillförlitliga resultat. Den extra exekveringstidenför klockcykelräkning uppmättes till 75 klockcykler. Med den här tekniken är detmöjligt att mäta hur mycket varje SIMD-instruktion bidrar till den totala exekveringstiden.Examensarbete presenterar också en metod att ordna instruktioner somhar databeroenden sinsemellan med hjälp av ovanstående tidsmätningsmetod, såatt antalet pipeline stalls minimeras. I de fall det behövdes, skrevs koden till algoritmernaom för att bättre kunna utnyttja ARM-arkitekturens specifika SIMDinstruktioner.Dessa jämfördes sedan med resultaten från kompilatorns automatgenereradevektoriseringkod. Exekveringstiden för SIMD-implementationerna varsignifikant kortare än för de kompilatorgenererade och visade på en förbättring påmellan 2,47 och 5,11 gånger, mätt i exekveringstid. Resultaten visade också på entydlig förbättring när instruktionerna exekveras i en optimal ordning. Resultatenvisar att automatgenererad vektorisering presterar sämre för komplexa algoritmeroch producerar maskinkod med signifikanta databeroenden som orsakar pipelinestalls, även med optimeringsflaggor påslagna. Med hjälp av metoder presenteradei det här examensarbete kan prestandan i DSP-algoritmer förbättras betydligt ijämförelse med automatgenererad vektorisering.

Full textAbstract:
The aim was to investigate the perception of whiteness in Nordic architecture and analyse the reasonsbehind the pale colour scheme in a public space context. The word pale was used alongsidewith white, since it gave broader possibilities to ponder over the topic. The geographical researcharea was framed to cover Sweden and Finland, although the search for underlying reasons extendedbeyond the borders of the North. Architecture was viewed as an entity, including both exteriors andinteriors. The focus was on reasoning around the question “why” to arouse professional discourseabout the often-unquestioned topic. Analysing the background of a commonly acknowledged phenomenonstrives to make architects more conscious of the background of their aesthetics so thatfuture decisions can be based on a more complex set of knowledge rather than leaning on tradition.Because of the wide demarcation of the research question, the project started with self-formulatedhypothesis, after which they were thoroughly analysed. The formulated pre-assumptions were, thatthe Nordic paleness is, firstly, a consequence of misinterpreted past architecture. Moreover, naturalcircumstances of the North, the symbolism connected to white and the tradition of canonisingmodernism were established as hypothesis. Lastly, architect education, combined with the tendencyof prototyping with white materials were assumed to endorse the pale colour scheme. The misinterpretations’possible implication in the perception of whiteness was also examined as a part of the research.Justification for the hypothesis was found, although broad framing meant that the referencematerial was splintered. Personal reflection was used as a means for cohesion. The paper includes aconcise artistic element in the form of an introductory poem to each chapter.Batchelor's thesis for Aalto university

Full textAbstract:
This creative project presents an overview of the architectural styles and history of the surviving commercial architecture of A.M. Strauss in Fort Wayne, Indiana. He was the best known architect working in Fort Wayne during the period covered by this creative project, and his work is an excellent example of how national architectural trends affected architecture in Fort Wayne. His commercial architecture represents his best known and most significant work. He did far too many buildings to cover in a single thesis, and so his residential and institutional architecture in Fort Wayne remains for another study, as do his many works outside of Fort Wayne. This project also brings together in one treatment as much photographic, historical and architectural documentation of these buildings as possible — documentation now scattered across east central and northeast Indiana. It traces Strauss's stylistic changes from Spanish Eclecticism through Art Deco and Art Moderne to Modernism. The surviving buildings represent each of these styles and shifts in historical context.Department of Architecture

This thesis investigates the architecture design studio by focusing on particular instances in the studio: Situations in which students "get stuck." This study first discusses what these situations involve: When do students consider themselves stuck, how can such situations be recognized in the studio and what are their possible causes. In this description "stuckness" is seen as a reaction to a breakdown in the relation between the student's actions and the requirements of his environment. In the second part of the thesis the notion of inquiry (as described by John Dewey) is applied as a research method and used to determine the cause of a specific situation. The structure and content of such inquiries is discussed through a detailed example. Although the thesis does not intend to devise solutions to "being stuck," the practical uses of the research method in the design studio are considered as well: Inquiries are also seen as a tool to illuminate student's problems and to provide opportunities to discuss issues that are crucial to the student's learning. The theoretical background of this study is drawn from work in several fields, including that of Kurt Lewin, John Dewey and Clifford Geertz. This thesis also relies on information gathered in informal interviews with architecture students and faculty and inquiries conducted within two design studios.

Full textAbstract:
Awareness is the experiencing in life. It is how you experience being yourself in your surroundings moment by moment. But of all the possible things you can be aware of in the moment, it is something that always takes the spotlight. Attention is that directing spotlight. Attention is the focus in the open field of awareness. Attention is something that we have all the time, but it seems to be constrained to the experience of a thought or emotion that we have in the moment. We have a feeling that we are our thoughts and therefor as soon as something arises in the mind, we have an urge to strive towards what´s pleasant and pushing away what´s not. But the attention is directed towards what seems more important at the moment and our values can therefor change due to the circumstance that we are in, and instead of acting in our environment, we react. Meanwhile we habitually direct our attention towards so many things that we hope will contribute to our wellbeing, that we don’t have time to see that we are directing the attention in the completely wrong direction. Wellbeing isn’t the effect of any outer condition, it is a state of mind. Our minds are the space where our lives are played out. Which means that the only thing we could possibly have control over, is how we respond to the situations that occur in our lives. To make us the director of our attention, to not lose more moments to a momentary reactive mind is hard. During my investigations of how Japanese architectural strategies activates the mind, the aim for my project was developed, to shape spaces that activates awareness. The challenge is to not direct the attention in another direction, but to put the attention on attention itself. This project tries to do this by merging body with space, or by making the mind the space.

How do we remember urban space? How can we measure what is remembered? This thesis presents a new approach to study urban spatial perception in an efficient, automated, and scalable way. It explores the use of novel tools developed for online surveys and data visualization. Previous studies in human spatial perception have used methods such as face-to-face interviews, questionnaires, recognition tasks and surveys that ask subjects to draw sketch maps. Those conventional methods produced significant urban studies such as the one by Kevin Lynch (1960), but they are laborious, sensitive to the individuality of subjects, prone to examiners' biases and conducted with a limited number of subjects. Their results are also difficult to quantify. In contrast, the method developed here uses geo-tagged street views and a web-based visual survey. An online experiment conducted in this thesis collected 394 participants in 20 days who were asked to guess the locations of street views from a familiar neighborhood. Results are presented in the form of interactive visualizations. Analysis revealed that memory for exact location of place improves with degree of interaction and proximity to center, rather than number of encounters; memory for one location may vary dramatically between different viewpoints. The results also suggest that the irregularity of urban structure doesn't prevent the forming of strong mental images. While this new method cannot completely replace face-to-face interviews, it demonstrates the possibility of using available technology to scale visual surveys to hundreds or even thousands of people and rapidly visualize the resulting data. It thus opens up new possibilities for large-scale, fine-grained studies in urban perception.

This thesis focuses on market valuation of attributes of single family housing in the Salt Lake City market. Using data from different sub-regions of Salt Lake County, this paper addresses the question of buyer demand with respect to home style. Using hedonic regression analysis, the thesis explores the premium or discount associated with different styles of homes. Analyzing the hedonic results in the context of the current housing stock in the Salt Lake Area provides interesting insights into how rambler, two-story, splitentry and tri-level homes are valued. The hedonic model shows that buyers pay a premium for ramblers across the different sub areas of Salt Lake City. Given this premium, the thesis explores what the optimal mix of home style might be in the two areas where considerable developable land remains.

An interactive three-dimensional computer animation system has been developed. The system consists of several graphical editors for creating and controlling articulated (jointed) figures and environments. The primary input device is a mouse, which the animator uses for drawing and choosing menu options. The editors are designed to allow the animator to create specialized drawings describing the subjects of the animation. Modelling data is generated automatically from the drawings. Movement can be controlled in a variety of ways. The animator can position each limb of the figure individually. use pre-programmed skills. or use implemented robotics algorithms. A path planning algorithm is available so characters can find a collision-free path when instructed to walk from one place to another. This is a first step towards goal-directed animation where animators will specify desired goals in terms such as "walk to the door and open it" and characters will know enough about "where they are" and how they can move to perform the appropriate motions.

Full textAbstract:
Only the African acacias have a so-called flat topped crown. This study identifies this architecture using the simple measures of height, diameter and spread. In this way the flat-topped species are identified and differentiated from the other acacia species (A. nilotica & A. tortilis). It has been suggested that this shape is an anti-herbivore mechanism. We demonstrate how these trees spend a lot of energy in defence, which indicates that the canopy shape is a poor anti-herbivore device. Measurements of the height of grass outside the canopies indicate that these species inhabit areas of long grass. At the same time, our data show that at least one of these species (A. nilotica) is extremely fire sensitive (60% mortality). The effect which saves these trees from fire is shorter grass beneath their crowns providing a low-fuel fire buffer for the trunk. However, none of the conventional effects of canopy are able to cause this effect (shade, nutrients). We propose that the shade and nutrient-rich undercanopy grass (as well as the pods of these animal-dispersed trees) encourages large grazing mammals to spend time under these trees. These animals then, are responsible for lowering the height of the grass cover by grazing and trampling, and hence save the trees from fire. We suggest an animal - flat-topped tree mutualism where food and shade are exchanged for seed dispersal and fire protection.

Full textAbstract:
This dissertation presents the findings of a descriptive study in enterprise architecture decision-making processes. Decisions regarding enterprise systems architecture are among the most complex decisions in the IS domain. Enterprise architecture evaluations and recommendations such as choice of an enterprise system and buy-versus-build applications are strategic decisions in the sense that they influence and constrain corporate decisions. Formal and informal methodologies are discussed in this dissertation regarding how enterprise architecture decisions ought to be made in an abstract, ideal situation (i.e., normatively) and in describing best practices (i.e., prescriptively). How enterprise architecture decisions are made in practice, however, has not been rigorously studied (i.e., descriptively). The first purpose of this research is to examine the processes by which enterprise architects make decisions in practice. Drawing on concepts from complex decision-making (e.g., heuristics, scripts, schema, etc.) and sociology (e.g., mimetic isomorphism), the aim of this paper is to understand architectural decision-making in practice from the descriptive view. A second purpose of this research is to provide at least the beginnings of a new theory for enterprise architecture decision-making processes. Using a grounded theory approach, the study uses systematically collected field data to clarify and refine concepts of architecture decision processes and how organizational issues influence them. This descriptive and empirical study was used to propose a new theory for conceptualizing the organizational environmental issues on enterprise architecture. The paper thus has important implications for research and practice.

This dissertation examines how Bosnian Muslims construct their identity through the lens of rebuilt or newly built mosques following the systematic destruction of religious architecture during the 1992-1995 War. The stylistic diversity of contemporary mosques in the region, I argue, reflects competing visions of how contemporary Bosnia should deal with its own history of coexistence and war. By examining different identity formation processes on three scales (the building process, the regional, and the global scale), the dissertation argues that, aside from its religious functions, the contemporary mosque has become the primary locus where the emerging Bosniak nation can visually and symbolically shape and express its visions of itself. I begin by outlining how the cultural and political history of Bosnian Muslims has been "written" and "rewritten" through religious architecture since the fifteenth century. I then investigate how during the war of the 1990s the nationalist extremists instrumentalized religious architecture to facilitate the realization of their expansionist projects. While all ethno-national groups in Bosnia experienced significant war losses, Bosnian Muslims suffered the greatest human and architectural casualties. I argue that the extent and the genocidal nature of war violence against them has transformed the meaning of the mosque from that of a place of worship and of a signifier of religious-ethnic identity to that of the ethnic body of the Bosniak nation. The notion that the mosque stands in for the human body was internalized by Bosnian Muslims in the form of two novel and programmatically delineated mosque genres defined here as the Inat Mosque and the Memorial Mosque. The first results from identity construction in response to the national myths and territorial claims of the Serbs and Croats, while the second represents identity creation that is linked to the community's own internal processes of commemoration. These regional negotiations of identity are challenged by two competing global imperial ideologies introduced to Bosnia by the Saudi and Turkish donors and manifest in monumental mosques they finance. As local builders compete with these supra-national Islamic networks, contemporary mosque architecture in Bosnia has become a site of negotiation and frictions between global and local interests. Throughout, the analysis highlights the significance of ethnic symbols, long-term cultural factors, and global cultural flows in the creation of contemporary nations.

This thesis explores the change in the building structures of a Northeastern Ecuadorian group, the Secoya of the Aguarico River. In the context of environmental activism and cultural survival there are many reasons to lament major alterations in the Secoya's lifestyle in recent years. One of the most visible transformations experienced by this group is the abandonment of several traditional architectural types, including the Jaihub'e or communitarian longhouse. The thesis focuses on understanding the forces that have influenced the Secoya decision to adopt the Zinc House type, a metallic-roofed individual housing unit. These include change in their economic systems, depletion of the natural resources necessary for traditional construction, Western cultural pressure, difficulty to adapt the traditional structures to a modern life, and finally a historical predisposition to change. In short, the Secoya changed firstly because everything around changed, leaving them with no other option, and secondly because, simply, human beings naturally tend to change. The change was meaningful for the Secoya because many building practices that were actively linked to social life were abandoned. It was meaningful for us outsiders because our expectations of an exotic culture were left unfulfilled when it changed. However, rather than the loss of another indigenous culture, what the case illuminates is the nature of our own expectations, those conforming to an urban, pop mythology regarding sustainability. We should follow the Secoya example and change our own urban mythology, because our mythology wrongly overvalues cultural idleness and nature as the means for guaranteeing sustainability;
(cont.) it emphasizes that sustainability depends on resource saving rather than on social justice, and it believes that sustainable solutions are an universal panacea that invariably applies to every culture, geography and historical context. The thesis seeks to expand the frontier of architectural theory towards an unconventional scenario, that of the Upper Amazon, in a series of specific topics: First, it provides detailed knowledge on three typologies of ethnic interest, one of them aboriginal (locally originated), one indigenous (locally adapted) and one modern (neutral-global). Second, it offers historical knowledge about the evolution of the Upper Amazonian building tradition. Third, it discusses how myth and building structure interact in the Upper Amazonian traditional house. Fourth, it details the serious cultural implications of the abandonment of the traditional types. Five, it presents knowledge about the environmental and social factors contributing to the abandonment of those types. And six, it helps to develop awareness about our own urban myths on sustainability in the context of change.

Find full textAbstract:
In order to reduce the invasiveness of implantable electronic sensor devices, a technology is needed that could create devices that behave soft and flexible as biological tissue but at the same time maintain their electronic functionality and resist to a high values of sheer and tensile stress. The main problem consists in producing a biocompatible material that stiffens at excessive strain and thus could prevent crack formation and delamination in the more fragile thin functional electronic layers. This thesis presents the methodology to fabricate and characterize a smart composite material composed by polymer nanofiber networks incorporated in an elastomeric matrix. Nanofiber networks of the biocompatible polymer Poly(L-lactic acid) (PLLA) are produced by electrospinning. The polymer Polydimethylsiloxane (PDMS) is used as the elastomeric matrix. The objective is to achieve a significant strain-stiffening transition by introducing a nanofiber network with controlled architecture. To this end a methodology is introduced that enables to synthetize polymer nanofibers with controlled curvature. Dynamical mechanical analysis (DMA) and Atomic Force Microscopy (AFM) are employed to characterize the mechanical properties of the composite material as well as of its single components. The results indicate that the mechanical response of the polymer can be largely controlled by the nanonetwork architecture. Stiff response to tensile stress is obtained when the fibers are straight and aligned in the stress direction. Soft and stretchable response results when fibers are curved or oriented parallel to the strain direction. The introduction of the methodology for fabrication as well as the characterization of such nanonetwork composites with controlled architecture will pave the way for further systematic studies leading to composites with tunable strain stiffening transition.

EnglishPh.D.
Nineteenth-century Britain experienced a confluence of a rapidly urbanizing physical environment, radical changes in the hierarchical relationships in society as well as in the natural sciences, and a nostalgic fascination with antiquities, especially gothic architecture. The realist novels of this period reflect this tension between dramatic social restructuring and a conservative impulse to remember and maintain the world as it has been. This dissertation focuses on the word structure to unpack the implications of these opposing forces, both for our understanding of the social structures that novels reflect, and the narrative structures that novels create. To address these issues, I examine the architectural structures described in Victorian realist novels, drawing parallels with their social and narrative structures. In Charles Dickens's Little Dorrit (1855), George Eliot's Adam Bede (1859), and Thomas Hardy's The Mayor of Casterbridge (1886) and Jude the Obscure (1895), descriptions of houses and barns, churches and cathedrals, shops and factories, and courthouses and schools are thematically important because they draw our attention to the novels' interest in the social structures that underlie the fictional worlds they represent. Buildings provide spaces where members of a community may work towards a shared purpose; they also embody that community's common knowledge, values, and ideals. These novels take up the thematic concern with structure through their own formal narrative structuring work. Much like an architect builds a physical structure, novels build a narrative structure by carefully arranging patterns, sequences, proportions, and perspectives. An examination of a novel's description of a building reveals moments of self-reflexive consideration of the narratives it constructs. These are moments that interrogate the building materials of narrative and how their arrangement becomes meaningful, that consider what the narrative structure can accommodate and what it excludes, and that invite us to attend to the ways in which the act of structuring a narrative situates it in time, in relation to the past, present, and future. The choices an architect makes about ornaments and materials, the way a building integrates the surrounding environment, and the way its proportions compare to a human scale, all constitute a kind of language; moreover, the way people interact with, in, and around these built spaces suggests it is a dynamic and evolving language. Preeminent Victorian art and social critic John Ruskin's architectural treatise, The Seven Lamps of Architecture (1849) serves as a master key to interpreting the Victorian understanding of architectural language in the novels under investigation. Because Ruskin's writings pervaded mid-century artistic discourse, and because he turned his critical gaze on such a wide range of the mid-nineteenth century's most important aesthetic, social, philosophical, and ethical concerns, his work provides an invaluable bridge between the physical, social, and narrative structures in these novels. Each of Ruskin's "lamps" represents a specific architectural principle; each chapter in this project pairs a novel with a lamp with thematic and formal resonance.

Full textAbstract:
Allocation of expensive resources, (such as Multiplier) onto the CGRA has been of interest from quite some time. For these architectural solutions to fulfill the designers' requirements, it is of utmost importance that the design offers high performance, low power consumption, and effective area utilization. The allocation problem is studied using the UntangledII gaming environment, which has been developed at the Reconfigurable Computing Lab at UNT to discover the design of custom domain-specific architectures. This thesis explores several case-studies to investigate the arrangement of functional units and interconnects to achieve a low power, high performance, and flexible heterogeneous designs that can fit for a suite of applications. In the later part, several human mapping strategies of top and bottom players to design a custom domain-specific architecture are presented. Some common trends that were examined while analyzing the mapping strategies of the players are also discussed.

Full textAbstract:
This empirical research explores secondary behavioural effects after energy efficiency improvements are carried out in residential properties. Three field studies were carried out to provide an original contribution to knowledge about rebound effects, behavioural spillover and the psychological constructs that may contribute to changes in behaviour after energy efficiency improvements are carried out in real-life settings. In the first two studies, residents in economically deprived communities in Wales who had energy efficiency improvements under the Arbed scheme were invited to complete a self-reported questionnaire about their behaviours, attitudes, subjective norms, perceived behavioural control and self-identity. The Arbed scheme was set up by the Welsh Government to provide home energy efficiency and renewable microgeneration measures for low-income and fuel-poor households in Wales. Residents from nearby communities served as a control for these studies. The first study was cross-sectional and explored whether there were any associations between energy efficiency measures and other energy-related measures. The second study was a longitudinal study and the occupants filled in the questionnaire both before and after the energy efficiency measures were installed. This study particularly explored whether the energy efficiency measures would lead to changes in other energy related behaviours. The results from both studies found no evidence of changes in other energy-related behaviours, suggesting positive spillover did not occur, but changes were found in some of the measured psychological constructs. Self-reported environmental identity increased for the energy efficiency improvement group after the measures were installed. For the third study, utility meter readings and indoor air temperatures were taken for a sub-sample of the occupants both before and after the energy efficiency measures were installed. There were few differences found between the two groups for indoor air temperature, but the energy efficiency improvement group was found to use less energy after the measures were installed. The actual energy saved for the energy efficiency improvement group was however lower than predicted and a rebound effect of 54% was calculated. This research is one of the few field studies in this area. The findings from the three studies suggest that after energy efficiency improvements are installed, the occupants may take back some, if not a considerable amount, of the potential energy savings to improve their thermal comfort. The findings also provide an indication that psychological mechanisms may change after energy efficiency measures are installed.

Full textAbstract:
Neoadjuvant chemotherapy has become standard practice in patients with high-risk early breast cancer as it improves rates of breast conservation surgery and enables prediction of recurrence and survival by using response to treatment as a surrogate. Previous studies have focused on generating molecular datasets to develop prediction models of response, though little is known on how tumours and their microenvironments are modulated by neoadjuvant chemotherapy. The thesis aims at molecularly characterising tumour changes during neoadjuvant chemotherapy in a cohort of 168 patients. Serial tumour samples at diagnosis, and, when available, midway through chemotherapy and on completion of treatment were profiled by shallow whole genome sequencing, deep exome sequencing and transcriptome sequencing, resulting in the generation of an unprecedented genomics dataset with tumours in situ while patients received chemotherapy. Molecular predictors of response to chemotherapy were inferred from the diagnostic biopsy. Several novel observations were made, including previously undescribed associations between copy number alterations, mutational genotypes, neoantigen load, HLA genotypes and intra-tumoural heterogeneity with chemosensitivity. Possible mechanisms of chemoresistance included LOH at the MHC Class I locus, decreased expression of MHC Class I and II genes and drug influx molecules, as well as increased expression of drug efflux pumps. A complex relationship between proliferation, tumour microenvironment composition (TME) and response to treatment was explored by deconvoluting bulk RNAseq data and performing digital pathology orthogonal validation. Clonal and microenvironment dynamic changes induced by/associated with chemotherapy were then modelled. Two types of genomic responses were identified, one in which the clonal composition was stable throughout treatment and another where clonal emergence and/or extinction was evident. Validation by multi-region deep sequencing confirmed the dynamics of the clonal landscape. Clonal emergence was shown to be associated with higher proliferation and decreased immune infiltrate, with an increase in genomic instability and homologous recombination deficiency during treatment. The immune TME composition and activity mirrored response to treatment, with cytolytic activity and innate and adaptive immune infiltrates linearly correlating with the degree of residual disease remaining after chemotherapy. Finally, the circulating tumour DNA (ctDNA) genomic landscape was explored by using shallow whole genome sequencing and targeted sequencing of plasma DNA. Tumour mutations detected on exome sequencing were also detected in ctDNA in plasma, supporting the use of liquid biopsies as a biomarker for monitoring response to therapy and detection of minimal residual disease.

Full textAbstract:
Service-oriented architecture enables web services to operate in a loosely-coupled setting and provides an environment for dynamic discovery and use of services over a network using standards such as WSDL, SOAP, and UDDI. Web service has both functional and non-functional characteristics. This thesis work proposes to add QoS descriptions (non-functional properties) to WSDL and compose various services to form a business process. This composition of web services also considers QoS properties along with functional properties and the composed services can again be published as a new Web Service and can be part of any other composition using Composed WSDL.
