I dagsläget när studenter från Kungliga Tekniska Högskolan (KTH) ska genomföra en examensarbetspresentation ska det finnas aktiva lyssnare på plats. Aktiva lyssnare är andra studenter som också utför examensarbeten och som lyssnar på presentationen och ställer frågor. Detta är ett obligatoriskt moment som alla studenter genomför under sina examensarbeten. Problemet med detta moment är att det inte genomförs på ett smidigt sätt, för att få sitt deltagande godkänt får man en underskrift på ett papper av examinatorn på plats som bevis på delaktighet. Skulle detta papper tappas bort finns inga bevis på delaktighet. I detta examensarbete ska närvaroprocessen göras smidigare, både för studenter och för examinatorer, med hjälp av digitalisering. Som student ska det vara enkelt att ställa frågor till presentatören, dessa frågor kommer vara en del av grunden för närvarokontrollen. För examinatorer ska närvarokontrollen av aktiv lyssnare deltagandet förenklas. Med hjälp av lärplattformen Canvas, som KTH använder sig av, ska det bli lättare för examinatorer att ta närvaro på studenter. Studenter ska med hjälp av en gruppfunktion i Canvas kunna välja vilken presentation de vill delta i genom att gå med i en grupp som representerar en vald presentationen. Canvas har också en diskussionsfunktion som gör det möjligt för aktiva lyssnare att ställa sina frågor om presentationen, frågorna kommer sedan vara ett underlägg för närvaro och deltagande under presentationen. Canvas kan med sitt applikationsprogrammeringsgränssnitt användas med programmeringsspråket Ruby, vilket är tänkta ska användas, för att digitalisera och förenkla aktiv lyssnare processen. Detta projekt har tagit fram en process som endast använder Canvas för bevis på närvaro och delaktighet som aktiv lyssnare under en presentation. Som aktiv lyssnare behöver man endast gå med i en grupp som representerar en presentation och publicera en fråga i en diskussionstråd i gruppen för att få delmomentet godkänt. Med denna process behöver varken studenter eller examinatorer hantera osmidigt pappersarbete. Resultatet är fullt fungerande och har testats på en fiktiv Canvasdomän och skulle i teorin kunna användas på KTH. / In today’s degree project presentations at the Royal Institute of Technology (KTH), there must be active listeners on site. Active listeners are other students who are also doing degree projects. They listen to the presentation and ask questions to the presenter. This is a mandatory assignment for every degree project student. The problem with this assignment is that the process of getting once attendance approved is implemented in an old-fashioned way, a signature from the examiner on site on a piece of paper is the only proof of participation. If the piece of paper is lost a student has no proof of participation. In this thesis the attendance process for active listeners will be improved both for students and examiners with the help of digitalization. As a student it should be easy to ask your questions to the presenter, these questions will then be a part of the attendance. As an examiner the attendance and active listening participation will be made easier to document and record. With the help of the learning management system Canvas, which KTH uses, attendance control for examiners will be made easier. Students will with the help of a group function in Canvas be able to choose which presentation they want to attend to by joining a group which represents a chosen presentation. With the help of a discussion function in Canvas, active listeners will post their questions to the presenter, the questions will then be used as a proof of attendance and participation during the presentation. With its application programming interface, Canvas can be used with the programming language Ruby, which is intended to be used to digitalize and simplify the active listening process. This project has developed a process that only uses Canvas for proof of presence and participation as an active listener. As an active listener, you only need to join a group representing a presentation and post a question in a discussion thread in said group to pass the assignment. With this process neither students nor examiners need to handle clumsy paperwork. The results are fully functional and have been tested against a custom Canvas domain and could in theory be used at KTH.

O Light Steel Frame (LSF) é um desses novos métodos, baseado em perfis de aço que trabalham em conjunto através de subsistemas estruturais, não requisitando água nem produção de materiais in loco. Não só a forma de construir deve ser atualizada para melhor utilizar os recursos produtivos, como também deve-se promover melhorias no gerenciamento das construções. Em virtude disso, uma crescente tecnologia que está cada vez mais sendo agregada na construção civil é a Modelagem De Informação Da Construção, ou simplesmente BIM, da sigla em inglês. BIM permite planejar, projetar, construir, usar e manter uma construção. Para isso, não é necessário que exista um aplicativo que englobe todas essas tarefas. Por utilizar informação parametrizada, aplicativos distintos podem compartilhar uma mesma informação e gerar seus resultados, processo esse denominado de interoperabilidade. Assim, este trabalho tem como foco principal desenvolver uma ferramenta capaz de modelar estruturas em LSF, realizar um pré-cálculo estrutural e também prover meios de permitir a interoperabilidade com outros softwares. Para este fim, foi empregado o SketchUp, que possui uma interface de programação em linguagem Ruby, e possui módulos de geração de dados compatíveis com as necessidades da interoperabilidade. Como resultado, a ferramenta gerada neste trabalho alcançou desempenho satisfatório, mesmo que ainda existam muitos recursos para serem agregados. / The large amount of construction waste currently generated in Brazil demands new construction methods and more industrialized process. The Light Steel Frame (LSF) is one of those new methods based based on structural subsystems comprising steel properties, not ordering water or production of material in loco. Building and its management should be improoved. Building Information Modeling, or simply BIM, allows the planning design, building using and maintaing of building. Therefore, it is not necessary to have an application that includes all these tasks. By means of parameterized information, different applications can share the same information and generate results, a process known as interoperability. This work is mainly focused on developing a tool capable of modeling structures in LSF, performing a structural pre-analysis and also providing a means to enable interoperability with other software. To this end, we applied the SketchUp, which has a programming interface in Ruby language, and has data generation modules compatible with the interoperability needs. As a result, the generated tool in this work has achieved satisfactory performance, even though there are still many resources to be aggregated.

Tracking an individual specimen can be a difficult task especially when one also has to keep track of the environmental factors that affect the tracked specimen’s behavior. The task of tracking these animals becomes impossible when they become submerged in water and their number increases to more than just one. The aquatic species that are being tracked by this project in Lake Pontchartrain and the Gulf of Mexico are: tarpon, scalloped hammerhead, whale shark, tiger shark, yellowfin tuna, spotted seatrout, redfish, and bull shark. We are tracking these fish using acoustic and satellite transmitters. The insertion of transmitters in the fish was handled by the Louisiana Department of Wildlife and Fisheries biologists. The acoustic transmitters were implanted on smaller fish that only swam in Lake Pontchartrain. Due to this, receivers were only implanted at locations across the lake on various types of attachments such as buoys, PVC pipes, and pilings. These receivers were positioned at more than ninety locations in order to maximize the acquisition of detections. These species were tracked in Lake Pontchartrain and the Gulf of Mexico. After this preliminary setup, a constant batch of data was generated on a regular basis and this data was process by the application developed in this project. A Ruby on Rails application was then setup in order to store this data and manipulate it to display an animated track. The application utilizes: Ruby, Rails, HTML, CSS, SQL, JavaScript and multiple third part libraries. Many optimizations were performed in order to ensure reliability and performance when loading a high volume of fish or if a high volume of users were to use the application.

Em sólidos dopados com Cr+3, o efeito não-linear ocorre devido à população de íons dopantes no estado metaestável, o qual possui uma polarizabilidade diferente do estado fundamental. Nestes materiais, o índice de refração não-linear n2 é proporcional a Δα/Is , onde Δα é a diferença de polarizabilidade, entre os estados, excitado (metaestável) e o fundamental, e Is a intensidade de saturação da transição. A técnica conhecida como Z-Scan é na atualidade a mais popular para medidas de n2 e foi recentemente aplicada em cristais dopados com Cr+3. Nestes materiais, o tempo de resposta do meio não-linear é dado pelo longo tempo de vida espontâneo do estado excitado τ0 (usualmente τ0 > 100 µs) tornando possível medidas da resposta transiente do sinal. Isto torna possível a normalização do sinal pela medida em t =O (quando o efeito não-linear ainda não se manifestou) com o intuito de eliminar efeitos lineares parasíticos (devido a imperfeições da superfície da amostra, não paralelismo, etc.). Neste trabalho 7 nós usamos o método de Z-Scan resolvido no tempo para determinar não apenas n2, mas também a intensidade de saturação Is. Nós introduzimos um novo método para determinação de Is, através da medida de Z-Scan transiente. Os valores de n2 e Is, podem ser usados para calcular a seção de choque da absorção no estado fundamental σ1, Δα e Δσ (a diferença de seção de choque de absorção entre o estado excitado e metaestável). , Fizemos medidas em cristais de rubi e alexandrita usando um laser de Ar modulado por um \"chopper\". No caso da alexandrita, o Cr+3 pode ocupar dois sítios que apresentam propriedades bastante diferentes. A técnica resolvida no tempo permite que se diferencie estes dois sítios, e então se determine n2, Is, τ0, Δα e Δσ para o íon de Cr+3 em cada tipo de sítio (no caso do sítio de espelho os valores de n2 e Δα são inéditos). / In Cr+3 doped solids, the nonlinearity originates from the population of dopant íon metastable excited state, which has a polarizability different from that of ground state. In these materials, the non-linear refractive index n2 is proportional to a Δα/Is, where a Δα is polarizability difference between excited and ground states and Is is the transition saturation intensity. The thecnique known as Z-Scan is nowadays the most popular one for n2 measurements and was recently applied to Cr+3 doped solids. In this material, the nonlinearity response time is given by the excited state spontaneous lifetime τ0 (usually τ0 > 100 µs) permitting transient response measurements. This allows signal normalization at t=0 (when the nonlinear effect did not appear yet) in order to eliminate parasitic linear effects (due to nonparallel sample surfaces, surface imperfections, etc.). In the present work we used a time resolved Z-Scan method to determine not only n2 but also the saturation intensity Is and these values can be used to calculate the ground state absorption cross section σ1, Δα and Δσ (where Δσ is the absorption cross section difference between excited and ground states). We introduced a new method to measure Is through transient Z-Scan measurements. We performed measurements in ruby and alexandrite using a chopped Ar+ ion laser. In the alexandrite crystal the Cr+3 ion can occupied two different sites that have very different spectroscopy properties. The time resolved technique allowed us to distinguished these two sites and then determine n2, σ0, Δα , Δσ and Is for the Cr+3 ion each kind of site(our n2, Δα and Is results for the mirror site are original contributions of these work).

Evolução de software é uma das atividades mais desafiadoras do processo de desenvolvimento de software. Uma importante questão associada à essa atividade é a correta compreensão do código fonte e outros artefatos que necessitam ser mantidos e evoluídos. Visando auxiliar desenvolvedores na manutenção de código, Integrated Development Environments (IDE’s) proporcionam ferramentas que informam desenvolvedores sobre as dependências e as particularidades do código a ser modificado. No entanto, linguagens dinamicamente tipadas não definem tipos explicitamente no código fonte, o que dificulta a análise estática do código e consequentemente a contrução dessas ferramentas. Como exemplo, a construção de call graphs (grafos de chamadas), utilizados pelas IDE’s para criar ferramentas de navegação de código, é prejudicada pela ausência da definição de tipos. Para abordar o problema da criação de call graphs para linguagens dinamicamente tipadas, propomos uma técnica dividida em passos para a construção de um call graph baseado em informações extraídas da execução de testes. A técnica é dividida em 3 passos, o Passo #1 cria um call graph conservativo e estático que resolve chamadas de métodos baseado apenas em nomes dos métodos, ainda no primeiro passo, testes são executados e seu traço de execução é armazenado para posterior análise. O Passo #2 combina a informação armazenada da execução dos testes e o call graph construído no primeiro passo, o Passo #2 também é responsável pela criação de um conjunto de regras de associação que servirão para guiar desenvolvedores durante a criação de novas partes do código. Nossa avaliação em uma aplicação real de porte grande mostrou que a técnica melhora a precisão do call graph criado removendo arestas desnecessárias (70%), e mostrou-se apta a auxiliar desenvolvedores definindo pontos de navegação no código baseada na análise de regras de associação extraídas do test-case-based call graph. / Evolving enterprise software systems is one of the most challenging activities of the software development process. An important issue associated with this activity is to properly comprehend the source code and other software assets that must be evolved. To assist developers on these evolution tasks, Integrated Development Environments (IDEs) build tools that provides information about the source code and its dependencies. However, dynamically typed languages do not define types explicitly in the source code, which difficult source code analysis and therefore the construction of these tools. As an example, the call graph construction, used by IDE’s to build source code navigation tools, is hampered by the absence of type definition. To address the problem of constructing call graphs for dynamic languages, we propose a technique based on steps to build a call graph based on test runtime information, called test-case-based call graph. The technique is divided in three steps; Step #1 creates a conservative and static call graph that decides target nodes based on method names, and the first step also run tests profiling its execution; Step #2 combines the test runtime information and the conservative call graph built in the first step to create the test-case-based call graph, it also creates a set of association rules to guide developers in the maintenance while creating new pieces of code; Finally, Step #3 uses the test-case-based call graph and the association rules to assist developers in source code navigation tasks. Our evaluation on a large-size real-world software shows that the technique increases call graph precision removing several unnecessary conservative edges ( %70), and assist developers filtering target nodes of method calls based on association rules extracted from the call graph.

Mass spectrometry (MS) has been a key player in biological investigation for some time and is the instrument of choice for high throughput proteomics. However, the generation of large, inherently rich, proteomics data sets has far outpaced our ability to utilize them to produce biological knowledge. The ultimate utility of MS proteomics is closely tied to our ability to interpret, integrate and validate this voluminous data. By way of introduction, I discuss the creation of the Open Proteomics Database, which aims to increase publicly available data and to encourage broader contribution from the statistical and bioinformatic communities. Next, I detail research efforts in the integration of mass spectrometry data sets to increase the number of quantifiable peptides. Comparing peptide quantities between experiments (or subsequent chromatographic fractions) in large numbers requires the chromatographic alignment of MS signals, a challenging problem. We use Dynamic Time Warping (DTW) and a bijective (one-to-one) interpolant to create a smooth warp function amenable to multiple alignment. We test a wide variety of alignment scenarios coupled with high confidence, overlapping peptide identifications to optimize and compare alignment parameters. We determine an optimal spectral similarity function, show the importance of penalizing gaps in the alignment path, and demonstrate the utility of our algorithm for multiple alignments. Then, we introduce a method to independently validate large scale proteomics data sets. We use known biases in sample constitution including amino acid content, transmembrane sequence content, and protein abundance to estimate peptide false identification rates (FIRs) in what we term sample bias validation (SBV). We use SBV to compare the false identification rate accuracy (FIRA) and recall capabilities of widely used techniques for error estimation in MS based proteomics. Finally, we describe the open source package mspire (mass spectrometry proteomics in Ruby). Mspire offers unified interfaces for working with a variety of file formats across the analytical pipeline, much needed converters between key formats, and tools for FIR determination. The package eases the burden of working with MS proteomics data, reducing the barrier of entry to developers and offering useful tools to analysts of MS proteomics data. / text

While producing the highest power output of any vertebrate, hovering hummingbirds must also precisely modulate the activity of their primary flight muscles to vary wingbeat kinematics and modulate lift production. By examining how electromyograms (EMGs) and wingbeat kinematics of hummingbirds change in response to varying aerodynamic power requirements during load lifting trials and air density reduction trials, we can better understand how aerodynamic power output is modulated via neuromuscular control. During both treatments increased lift was achieved through increased stroke amplitude, but wingbeat frequency only increased during air density reduction trials. These changes in wingbeat kinematics were matched by increased EMG intensities as aerodynamic power output requirements increased. Despite the relative symmetry of the hovering downstroke and upstroke, the timing of activation and number of spikes per EMG burst were consistently different in the supracoracoideus compared to the pectoralis, likely reflecting differences in muscle morphology.
