description: Schatten helfen dabei, räumliche Zusammenhänge zu begreifen, und sind aus modernen Echtzeitvisualisierungen nicht mehr wegzudenken. In der Echtzeitgrafik werden häufig Shadow-Mapping Verfahren in Kombination mit Tiefpassfiltern verwendet um visuell ansprechende Schatten zu erzeugen. Der weichzeichnende Effekt dieser Filter hat den Vorteil, dass Fehler, die bei beim Abtasten der Szenengeometrie entstehen, versteckt werden können, was wiederum die visuelle Qualität der erzeugten Schatten erhöht. Ziel dieser Arbeit ist es, diese Filter auszunutzen, um eine Funktion aus dem Radius des Weichzeichnungsfilters und der Abtastrate der Shadow Map herzuleiten, die es ermöglicht, Rechenleistung einzusparen, während der optische Eindruck der Schatten erhalten bleibt. Im Verlauf dieser Arbeit werden wir ergründen, wie diese Fehler entstehen und wie man sie vermeiden kann. Eine Studie hilft uns dabei, ein optimales Verhältnis zwischen der Abtastfrequenz der Shadow Map und dem Radius des Filters zu finden. Aus den Ergebnissen der Studie leiten wir dann eine Formel ab und entwickeln einen Algorithmus, mit dem sich bestehende Shadow-Mapping Algorithmen erweitern lassen können. Anhand der Implementierung eines Prototyps können wir zeigen, dass sich mit unserer Methode in vielen Fällen die Sampling Frequenz reduzieren lässt und Rechenleistung eingespart werden kann.
description: Shadows are an indispensable aid for understanding spatial relations of objects in natural scenes, which is why they are very important for real-time rendering applications. Combining filtering techniques with shadow mapping is a common tool to simulate visually pleasing shadows in interactive applications. A positive effect of such approaches is that filtering blurs aliasing artifacts caused by sampling the discretized geometric data stored in the shadow map, thereby improving the visual quality of the shadow. The goal of this thesis is to exploit common filtering algorithms in order to find a function of blur radius and shadow-map sampling frequency, which allows for optimized computational performance while mostly preserving the visual quality of the shadow. In the course of this work, we investigate how shadow artifacts arise and how to hide them. We set up and execute a user study to find the optimal relation between the shadow-map sampling frequency and the filter radius. From the results of the user study, we derive a formula and develop an algorithm that can be incorporated into existing shadow-mapping algorithms. We evaluate our results by applying the algorithm to a custom-made rendering framework and observe an increase in processing speeds.

description: We present a method to generate probability distributions that correspond to metrics obeying partial differential equations generated by extremizing a functional $J[g^{μν}(θ^i)]$, where $g^{μν}(θ^i)$ is the Fisher metric. We postulate that this functional of the dynamical variable $g^{μν}(θ^i)$ is stationary with respect to small variations of these variables. Our approach enables a dynamical approach to Fisher information metric. It allows to impose symmetries on a statistical system in a systematic way. This work is mainly motivated by the entropy approach to nonmonotonic reasoning.

description: PyPartMC is a Pythonic interface to PartMC, a stochastic, particle-resolved aerosol model implemented in Fortran. Both PyPartMC and PartMC are free, libre, and open-source. PyPartMC reduces the number of steps and mitigates the effort necessary to install and utilize the resources of PartMC. Without PyPartMC, setting up PartMC requires: working with UNIX shell, providing Fortran and C libraries, and performing standard Fortran and C source code configuration, compilation and linking. This can be challenging for those less experienced with computational research or those intending to use PartMC in environments where provision of UNIX tools is less straightforward (e.g., on Windows). PyPartMC offers a single-step installation/upgrade process of PartMC and all dependencies through the pip Python package manager on Linux, macOS, and Windows. This allows streamlined access to the unmodified and versioned Fortran internals of the PartMC codebase from both Python and other interoperable environments (e.g., Julia through PyCall). Consequently, users of PyPartMC can setup, run, process and visualize output of PartMC simulations using a single general-purpose programming language.

description: Many interfaces exist to create a single map, but few for creating a sequence, or story from a collection of maps. Taking a 3 stage user centred design approach, this thesis designs an interface which addresses this technological gap by focusing on the requirements of the journalist. In the first stage, semi-structured expert interviews elicit user requirements and use case scenarios for the new interface. Second, existing candidate software was evaluated based on these requirements. Significant shortfalls were found particularly in guidance for the structure of a story and the ability to share the output to social media. An interface focusing on six of the requirement shortfalls was then designed and evaluated through use case scenarios, using a case study from the Malaria Atlas Project. The research concludes that a redesign of the walkthrough to aid the novice user in creating an online cartographic data comic is required before a full working prototype system can be developed.

description: Hybrid mode-locking has been widely used in enhancing pulse quality, however how the hybrid two mode-locking techniques work remains unclear. In this paper, we experimentally investigate three pulse formation mechanisms in saturable absorbers (SA) and nonlinear polarization evolution (NPE) passively hybrid mode-locked fiber laser, which are SA-dominated, NPE-dominated, and SA-NPE co-domination switching. Clarified the exists dynamic competition and cooperation among the mode-locking techniques. For the first time, the method of simulating filtered gain spectrum with customized filtering is proposed, and the switching of pulse formation mechanisms is numerically investigated using the coupled Ginzburg-Landau equations. Our results deepen the understanding of hybrid mode-locked fiber lasers and provided a foundation for multi-wavelength mode-locked lasers with different mode-locking techniques in a single cavity.
An ex-situ study of polymer electrolyte membrane fuel cell gas diffusion layer durability under steady-state and freezing conditions
Creators: name: Lee, Charles Sim Jem
Publisher: name: University of British Columbia
Year: 2011

description: Polymer electrolyte membrane fuel cells (PEMFCs) are being developed to meet the lifetime requirements expected in commercial applications. While the effect of the gas diffusion layer (GDL) on performance has been studied, little is known of the impact of GDL materials and designs on PEMFC durability. Successful development of durable components such as the GDL is essential to achieving PEMFC system requirements for commercial applications. In this study, GDL compressive strain under steady-state and freezing conditions, and the effects of freezing conditions on GDL properties of electrical resistivity, bending stiffness, air permeability, surface contact angle, porosity and water vapor diffusion were studied. A GDL was aged ex-situ and its characteristics were evaluated as a function of aging time. GDL strain was measured to occur under steady-state aging conditions (80 °C and 200 psi). A maximum strain of 0.98 % was measured over 1500 hours of aging time. Increasing temperature to 120 °C or applied load to 400 psi resulted in maximum strains of 2.0 % and 1.5 %, respectively. Water phase transition during freezing conditions (54 freeze-thaw cycles between -35 and 20 °C) had no effect on GDL strain. No change in in-plane electrical resistivity, bending stiffness, surface contact angle, porosity and water vapor diffusion, through 50 consecutive freeze-thaw cycles between -35 and 20 °C, was measured. An increase in in-plane and through-plane air permeability (18 and 80 % respectively) was attributed to material loss during permeability measurements. Ex-situ tests showed that convective air flow can cause material loss, resulting in increased permeability and further convection. The GDL was shown to be much more resilient to material loss in the absence of water phase transitions.

description: O microcrédito tem sido um fator que vem a contribuir para o desenvolvimento econômico-social de toda a nação. Um dos maiores desafios do governo e da sociedade brasileira é estabelecer políticas que promovam o desenvolvimento econômico e social, com o objetivo de gerar emprego e renda para as populações mais pobres. A grande maioria dos pequenos empreendimentos informais não tem acesso ao crédito, por não atender às exigências de garantia dos financiamentos bancários. Necessário se faz apresentar instrumentos e estratégias adequadas às necessidades específicas desses pequenos empreendimentos. O Microcrédito, pelo uso de metodologia específica (aval solidário, agentes de crédito, entre outros) surge como uma das alternativas de combate à pobreza. O estudo procurou caracterizar o perfil dos tomadores de microcrédito em Sena Madureira, no estado do Acre, a partir dos levantamentos sócio-econômicos realizados pelos agentes de crédito, antes de receberem o pequeno empréstimo realizado com as famílias, através do Projeto Semente.

Nesse sentido, realizou-se estudo de caso objetivando conhecer as principais demandas tecnológicas do estado de Rondônia a partir da visão de técnicos da extensão e de produtores rurais e suas percepções acerca do processo de inovação tecnológica da Embrapa Rondônia. Os resultados obtidos indicam haver uma boa imagem dos técnicos da extensão acerca do trabalho e da importância da empresa como indutora do desenvolvimento tecnológico local. No caso dos produtores, embora estes considerem o trabalho da empresa importante, o nível de conhecimento e uso de tecnologias geradas por ela mostrou-se baixo, bem como seu processo de comunicação com ambos os atores falho, revelando um descompasso entre as atividades de pesquisa e de extensão rural, não obstante o estoque tecnológico existente permitir o atendimento às principais demandas tecnológicas advindas do setor de produção.

description: Code translation aims to convert source code from one programming language (PL) to another. Given the promising abilities of large language models (LLMs) in code synthesis, researchers are exploring their potential to automate code translation. The prerequisite for advancing the state of LLM-based code translation is to understand their promises and limitations over existing techniques. To that end, we present a large-scale empirical study to investigate the ability of general LLMs and code LLMs for code translation across pairs of different languages, including C, C++, Go, Java, and Python. Our study, which involves the translation of 1,700 code samples from three benchmarks and two real-world projects, reveals that LLMs are yet to be reliably used to automate code translation -- with correct translations ranging from 2.1% to 47.3% for the studied LLMs. Further manual investigation of unsuccessful translations identifies 15 categories of translation bugs. We also compare LLM-based code translation with traditional non-LLM-based approaches. Our analysis shows that these two classes of techniques have their own strengths and weaknesses. Finally, insights from our study suggest that providing more context to LLMs during translation can help them produce better results. To that end, we propose a prompt-crafting approach based on the symptoms of erroneous translations; this improves the performance of LLM-based code translation by 5.5% on average. Our study is the first of its kind, in terms of scale and breadth, that provides insights into the current limitations of LLMs in code translation and opportunities for improving them. Our dataset -- consisting of 1,700 code samples in five PLs with 10K+ tests, 43K+ translated code, 1,748 manually labeled bugs, and 1,365 bug-fix pairs -- can help drive research in this area.

description: As transformações pelas quais passa a sociedade aprofundam a interdependência da agricultura com as funções de insumos, equipamentos e máquinas agropecuárias, processamento e transformação, distribuição e consumo, surgindo daí o termo sistema agroindustrial ou agronegócio. Dentre os vários segmentos produtivos que compõem os sistemas agroindustriais brasileiro, a fruticultura vem ganhando projeção tanto no mercado interno quanto no mercado externo, em virtude de novas demandas que vêm surgindo, decorrentes principalmente de novos hábitos de consumo na busca de uma vida mais saudável. Em Rondônia, apesar da baixa participação no PIB do agronegócio do estado, a fruticultura constitui-se em fonte de renda e em alternativa interessante de diversificação das atividades agropecuárias. Visando conhecer a realidade da atividade no estado, foi proposta e realizada pesquisa, de caráter exploratório, com os atores da cadeia agroindustrial de frutas, com o objetivo principal de identificar as interrelações existentes no sistema, por meio da caracterização, análise e divulgação da situação atual da produção, processamento e comercialização das principais frutas cultivadas e comercializadas. Os resultados indicam haver pouca coordenação entre os elos dessa cadeia, o que conduz à necessidade de se estabelecer ações conjuntas e melhor interação entre eles, visando superar as dificuldades que se apresentam para o sistema como um todo.

description: Employing daily wind data from the ECMWF, we perform passive particle advection to estimate the Lagrangian velocity correlation functions (LVCF) associated with the midlatitude tropospheric flow. In particular we decompose the velocity field into time mean and transient (or eddy) components to better understand the nature of the LVCF's. A closely related quantity, the absolute dispersion (AD) is also examined. Given the anisotropy of the flow, meridional and zonal characteristics are considered separately. The zonal LVCF is seen to be non-exponential. In fact, for intermediate timescales it can either be interpreted as a power law of the form $τ^{-α}$ with $ 0

description: Porous electrodes were developed using laser powder bed fusion of Inconel 718 lattice structures and electrodeposition of a porous nickel catalytic layer. Laser energy densities of ~83-333 J/m were used to fabricate ~500 um thick electrodes made of body centered cubic unit cells of 200-500 um and strut thicknesses of 100-200 um. Unit cells of 500 um and strut thickness of 200 um were identified as optimum. Despite small changes in feature sizes by the energy input, the porosity of >50% and pore size of ~100 um did not change. In a subsequent step, we used nickel electrodeposition to create smaller scale pores on the electrode. The electrochemical performance of the electrodes for hydrogen/oxygen evolution reaction (HER/OER) was evaluated in a three-electrode setup. For HER, a much larger maximum current density of ~ -372 mA/cm2 at a less negative potential of ~-0.4 V vs RHE (potential against reversible hydrogen electrode) was obtained in the nickel-coated samples, as compared to -240 mA/cm2 at ~-0.6 V in the bare one, indicating superior performance of the coated sample. Conversely, OER exhibited minor performance differences upon application of the coating, indicating insignificant dependence of OER to surface composition and available surface.

description: Este trabalho descreve as modalidades de financiamentos agrícolas que poderão ser obtidas pelo agricultor. Neste estudo, consideraram-se as necessidades do produtor cafeeiro em estar optando pelo melhor crédito a ele fornecido. Tais créditos podem derivar-se a partir de financiamentos agrícolas, créditos rurais, aplicações compulsórias e recursos das autoridades monetárias que poderão ser utilizados em benefício do produtor rural. Investiga-se o grau de conhecimento pelos agricultores das fontes financiadoras das lavouras cafeeiras da região de Londrina, Estado do Paraná. A principal conclusão do estudo é que o agricultor da região estudada, não conhece todos os financiamentos agrícolas que podem beneficia-lo. O pequeno e médio agricultor teme os financiamentos, seja pela possibilidade de quebra na produtividade, pelas intempéries climáticas, pelas elevadas taxas de juros bancários, pela dificuldade na renegociação de prazos para as parcelas do financiamento, ou seja pela queda dos preços praticados no mercado. Observou-se neste estudo a existência de cafeicultores descapitalizados e com inserção comercial precária. Todavia, tais agricultores têm importante participação na produção de alimentos para a região Londrinense, ainda que enfrentem grandes dificuldades para acessar os financiamentos. Dificuldades essas determinadas pela falta de capacitação, infraestrutura, assistência técnica e extensão rural, e apoio à comercialização.

description: Listening to echoes has long been a way to estimate distances, a technique whose backbone is the time delay. The gravitational field also creates a time delay, called Shapiro time delay, that helps us extract some information from the field and is indeed due to the photon journey through the field. Here, the ability of the Shapiro effect to distinguish naked singularities from non-naked ones (black holes) is discussed. It is also inferred that this time delay may be hired to compare the various types of singularities with different dimensions. Besides them, the possibility of detecting the rotation of the assumed objects through surveying the gravitational time delay is also addressed.

description: The performance of ensemble-based data assimilation techniques that estimate the state of a dynamical system from partial observations depends crucially on the prescribed uncertainty of the model dynamics and of the observations. These are not usually known and have to be inferred. Many approaches have been proposed to tackle this problem, including fully Bayesian, likelihood maximization and innovation-based techniques. This work focuses on maximization of the likelihood function via the expectation-maximization (EM) algorithm to infer the model error covariance combined with ensemble Kalman filters and particle filters to estimate the state. The classical application of the EM algorithm in a data assimilation context involves filtering and smoothing a fixed batch of observations in order to complete a single iteration. This is an inconvenience when using sequential filtering in high-dimensional applications. Motivated by this, an adaptation of the algorithm that can process observations and update the parameters on the fly, with some underlying simplifications, is presented. The proposed technique was evaluated and achieved good performance in experiments with the Lorenz-63 and the 40-variable Lorenz-96 dynamical systems designed to represent some common scenarios in data assimilation such as non-linearity, chaoticity and model misspecification.

description: We report the discovery of SDSSJ1049+5103, an overdensity of resolved blue stars at (α_{2000}, δ_{2000}) = (162.343, 51.051). This object appears to be an old, metal-poor stellar system at a distance of 45 +/- 10 kpc, with a half-light radius of 23$\pm 10$ pc and an absolute magnitude of M_V = -3.0^{+2.0}_{-0.7}. One star that is likely associated with this companion has an SDSS spectrum confirming it as a blue horizontal branch star at 48 kpc. The color-magnitude diagram of SDSSJ1049+5103 contains few, if any, horizontal or red giant branch stars, similar to the anomalously faint globular cluster AM 4. The size and luminosity of SDSSJ1049+5103 places it at the intersection of the size-luminosity relationships followed by known globular clusters and by Milky Way dwarf spheroidals. If SDSSJ1049+5103 is a globular cluster, then its properties are consistent with the established trend that the largest radius Galactic globular clusters are all in the outer halo. However, the five known globular clusters with similarly faint absolute magnitudes all have half-mass radii that are smaller than SDSSJ1049+5103 by a factor of $\gtrsim$ 5. If it is a dwarf spheroidal, then it is the faintest yet known by two orders of magnitude, and is the first example of the ultra-faint dwarfs predicted by some theories. The uncertain nature of this new system underscores the sometimes ambiguous distinction between globular clusters and dwarf spheroidals. A simple friends-of-friends search for similar blue, small scalesize star clusters detected all known globulars and dwarfs closer than 50 kpc in the SDSS area, but yielded no other candidates as robust as SDSSJ1049+5103.

Disturbances in Influence of a Shepherding Agent is More Impactful than Sensorial Noise During Swarm Guidance

description: The guidance of a large swarm is a challenging control problem. Shepherding offers one approach to guide a large swarm using a few shepherding agents (sheepdogs). While noise is an inherent characteristic in many real-world problems, the impact of noise on shepherding is not a well-studied problem. We study two forms of noise. First, we evaluate noise in the sensorial information received by the shepherd about the location of sheep. Second, we evaluate noise in the ability of the sheepdog to influence sheep due to disturbance forces occurring during actuation. We study both types of noise in this paper, and investigate the performance of Strömbom's approach under these actuation and perception noises. To ensure that the parameterisation of the algorithm creates a stable performance, we need to run a large number of simulations, while increasing the number of random episodes until stability is achieved. We then systematically study the impact of sensorial and actuation noise on performance. Strömbom's approach is found to be more sensitive to actuation noise than perception noise. This implies that it is more important for the shepherding agent to influence the sheep more accurately by reducing actuation noise than attempting to reduce noise in its sensors. Moreover, different levels of noise required different parameterisation for the shepherding agent, where the threshold needed by an agent to decide whether or not to collect astray sheep is different for different noise levels.

description: We generalize earlier results of Fokas and Liu and find all locally analytic (1+1)-dimensional evolution equations of order $n$ that admit an $N$-shock type solution with $N\leq n+1$. To this end we develop a refinement of the technique from our earlier work (A. Sergyeyev, J. Phys. A: Math. Gen, 35 (2002), 7653--7660), where we completely characterized all (1+1)-dimensional evolution systems $\bi{u}_t=\bi{F}(x,t,\bi{u},\p\bi{u}/\p x,...,\p^n\bi{u}/\p x^n)$ that are conditionally invariant under a given generalized (Lie--Bäcklund) vector field $\bi{Q}(x,t,\bi{u},\p\bi{u}/\p x,...,\p^k\bi{u}/\p x^k)\p/\p\bi{u}$ under the assumption that the system of ODEs $\bi{Q}=0$ is totally nondegenerate. Every such conditionally invariant evolution system admits a reduction to a system of ODEs in $t$, thus being a nonlinear counterpart to quasi-exactly solvable models in quantum mechanics.

description: Since the work of Feenstra (2002), the standard Anderson & van Wincoop (2003) Gravity Model has been estimated using a fixed effects approach. However, a fixed effects approach has a major drawback: it does not allow for the estimation of exporter- and importer-invariant variables. Thus, economically relevant variables such as exporter and importer gross domestic product are disregarded. Here, we propose a random intercept model to address this gap. This approach not only provides identical estimates to a fixed effects approach, but also allows for the estimation of exporter- and importer-invariant variables.
