Laser-based diagnostic methods are being applied to more and more flows of theoretical and practical interest and are revealing interesting new flow features. Imaging particles or droplets in Nephelometry and Laser Sheet Dropsizing methods requires a tradeoff between maximised signal to noise ratio, without over-saturating the detector. Droplet imaging results in lognormal pdf (probability density function) distribution of pixel intensity. It is possible to fit a lognormal distribution to the histogram of pixels intensities. If pixel intensities are clipped at a saturated value it is possible to estimate a presumed pdf shape without the effects of saturation from the lognormal fit to the unsaturated histogram. Information about presumed shapes of the pixel intensity pdf is used to generate corrections that can be applied to data to account for saturation. The effects of even slight saturation are shown to be a significant source of error on the derived average. It is found that errors on the determined average exceed 5% when the number of saturated samples exceeds 3% of the total. This study also attempts to delineate limits, within which, the detector saturation can be accurately corrected. It is demonstrated that a simple method for reshaping the clipped part of the pixel intensity histogram makes accurate corrections to account for saturated pixels. These outcomes can be used to correct a saturated signal...

Brueckner-Hartree-Fock calculations are performed for nuclear matter with an exact treatment of the Pauli exclusion operator and single particle energy in the Bethe-Goldstone equation. The differences in the binding energy, compared to the commonly used approximations, are non-negligible. These differences lead to a larger binding energy around the calculated saturation point. Furthermore the Dirac structure of the nucleon self-energy in symmetric nuclear matter as well as neutron matter is derived from Dirac-Brueckner-Hartree-Fock calculations. It is demonstrated that the effects of correlations on the effective Nucleon-Nucleon interaction in the nuclear medium can be parametrised in terms of an effective meson exchange. This analysis leads to a very intuitive interpretation of correlation effects and also provides an efficient parametrisation of the effective interaction to be used in relativistic structure calculations for finite nuclei.; Bei der im Jahr 2001 vom Autor selbst produzierten Datei main.pdf kommt es auf modernen Betriebssystemen mittlerweile zu Anzeigeproblemen. Zur Behebung der Probleme wurde am 22.7.15 die aus dem originalen Autorenformat von der UB produzierte inhaltlich und formal identische pdf-Datei main2.pdf bereitgestellt.; Brueckner-Hartree-Fock Rechnungen werden in Kernmaterie unter Beruecksichtigung des exakten Pauli-Operators und der Einteilchenenergie in der Bethe-Goldstone Gleichung durchgefuehrt. Die Unterschiede in der Bindungsenergie sind im Unterschied zu den normalerweise verwendeten Naeherungen nicht vernachlaessigbar. Diese Unterschiede bedingen eine groessere Bindungsenergie im Bereich des berechneten Saettigungspunktes.

The Field Monte Carlo or Stochastic Fields method for turbulent reacting flows has been applied to the issue of sub-grid scale emission heterogeneity in a mesoscale model. This method is a solution technique for the probability density function (PDF) transport equation and can be seen as a straightforward extension of currently used mesoscale dispersion models. It has been implemented in an existing mesoscale model and the results compared with Large-Eddy Simulation data simulation devised to test specifically the effect of sub-grid scale heterogeneity on upper-air concentration fluctuations. The sub-grid scale emission heterogeneity is assimilated in the model as a PDF of the emissions. The results show an excellent agreement without the need of setting any model constant other than the ones already used in the mesoscale model. The stochastic Fields method solve for the PDF of concentration of dispersing scalars and therefore it posses the ability of handling chemistry of any complexity without any closure assumption. This study shows for the first time the feasibility to apply this method to mesoscale chemical transport models.; JRC.H.4-Transport and air quality

The stochastic fields method for turbulent reacting flows has been applied to the issue of sub-grid scale emission heterogeneity in a mesoscale model. This method is a solution technique for the probability density function (PDF) transport equation and can be seen as a straightforward extension of currently used mesoscale dispersion models. It has been implemented in an existing mesoscale model and the results are compared with Large-Eddy Simulation (LES) data devised to test specifically the effect of sub-grid scale emission heterogeneity on boundary layer concentration fluctuations. The sub-grid scale emission variability is assimilated in the model as a PDF of the emissions. The stochastic fields method shows excellent agreement with the LES data without adjustment of the constants used in the mesoscale model. The stochastic fields method is a stochastic solution of the transport equations for the concentration PDF of dispersing scalars, therefore it possesses the ability to handle chemistry of any complexity without the need to introduce additional closures for the high order statistics of chemical species. This study shows for the first time the feasibility of applying this method to mesoscale chemical transport models.; JRC.F.8-Sustainable Transport (Ispra)

Bimetallic palladium-gold (PdAu) nanoparticle (NP) catalysts have been demonstrated for the better catalytic performance than monometallic Pd catalysts in various reactions; however, the enhancement mechanism is not completely clear for most reactions. This thesis addresses the investigation of PdAu NP catalysts with emphasis on the structureproperty relationships in water-phase reactions, using hydro dechlorination (HDC) of trichloroethene (TCE) as the model reaction. Catalyzed TCE HDC is a potential approach for water pollution control, in which colloidal Pd-decorated Au NPs (Pdf Au NPs) are known to be significantly better catalysts than monometallic Pd ones. X-ray absorption spectroscopy (XAS) of carbon-supported Pdf Au NPs with different surface Pd coverages verified their core-shell structure (Au-rich core and Pdrich shell). Structure evolution was observed upon heat treatment, in which Pd was in the form of surface Pd ensembles at room temperature. The metals formed a surface PdAu alloy or a bulk PdAu alloy above 200°C, as determined from the average coordination environment. Results suggested a new way to promote Pd catalysis, namely, by impregnating supported Pd catalysts with gold salt followed by thermal annealing; such post-impregnation with different heat treatments could lead to >15-fold increase in TCE HDC activity. Pd ensembles on the Au NP surface were demonstrated to be major active sites for TCE HDC as the reaction rates correlated strongly with the size of Pd ensembles determined from XAS. The geometric effect...

IEEE Journal of Selected Topics in Earth Observations and Remote Sensing; Near-real time ocean surface currents derived from satellite altimeter (JASON-1, GFO, ENVISAT) and scatterometer (QSCAT) data on 1 degrees X 1 degrees resolution for world oceans (60 degrees S to 60 degrees N) are available online as “Ocean Surface Current Analyses-Real Time (OSCAR).” The probability distribution function (PDF) of the current speeds (w) , constructed from global OSCAR data from 1992 to 2008, satisfies the two-parameter Weibull distribution reasonably well, and such a PDF has little seasonal and interannual variations. Knowledge on PDF of w will improve the ensemble horizontal flux calculation, which contributes to the climate studies.

Communications in Mathematical Sciences, Volume 3, Issue 4, 605-620, 2005.; We solve the Smoluchowski equation for steady state solutions of rigid nematic polymers and suspensions under imposed elongational flow, magnetic or electric fields, respectively. Under the three imposed fields, we show that (1) the Smoluchowski equation can be cast into a generic form, (2) the external field must parallel to one of the eigenvectors of the second moment tensor in steady states, and (3) the steady state solution of the Smoluchowski equation (probability density function or simply pdf) is of the Boltzmann type parameterized by material parameters and two order parameters governed by two algebraic-integral equations. Then, we present a complete bifurcation diagram of the order parameters with respect to the material parameters by solving the algebraic-integral equations. The stability of the pdf solutions is inferred from the minimum of the free energy density. The solution method is extended to dilute solutions of dipolar, rigid nematic polymers under an imposed electric field. The first moment of the steady state pdf is shown to be parallel to the external field direction at sufficiently strong permanent dipole or relatively weak dipole-dipole interaction. In this case...

Blind source separation consists on estimating n source signals from m measurements generated through an unknown mixing process of the sources. In the underdetermined case where we have more sources than measurements, we divide the problem into two stages: estimation of the mixing matrix and inversion of the linear problem. This paper deals with the first stage. It is well known that when the sparsity of the sources premise is true, measurements tend to align with the columns of the mixing matrix, so the problem can be formulated as estimating the peaks of multidimensional probability density functions (PDF). In this paper we analyze two different techniques to estimate this peaks: one is to convert the multidimensional PDF into the power spectral density (PSD) of multiple complex sinusoidal signals and use different multidimensional espectral estimation techniques to detect the peaks. The other is to convert the (m − 1)- multidimensional PDF to m − 1 unidimensional projections and estimate the peaks of these.

El objetivo de esta tesis es desarrollar nuevas técnicas de extracción lineal de características para clasificación, mediante el uso de criterios basados en teoría de la información. Dado que esta teoría establece un marco que permite medir el grado de dependencia entre variables aleatorias o señales, nos proporciona una buena medida del nivel de relevancia de las características extraídas respecto a la clase a la que pertenece cada muestra. Se exploran dos aproximaciones distintas. La primera de ellas está basada en funciones de contraste que aproximan la información mutua entre las proyecciones obtenidas individualmente y las clases. En la segunda, se plantea como criterio a optimizar el test de hipótesis que sirve como regla de clasificación. La aproximación basada en funciones de contraste hace uso de una estimación de la información mutua similar a otra que ha sido usada con éxito en análisis de componentes independientes. La estimación utiliza momentos sobre funciones no polinomiales aplicadas a los datos. De esta forma, no es necesario el modelo de la función densidad de probabilidad (FDP) de los datos. Al ser derivables estas funciones, es posible su optimización mediante ascenso por gradiente. El método basado en la maximización del test de hipótesis hace uso de un modelo de Parzen para estimar la FDP de los datos. Se propone un algoritmo para optimizar dichos modelos de acuerdo con el criterio de máxima verosimilitud combinado con un procedimiento de validación cruzada. Su aplicación al problema de extracción lineal de características consiste en la maximización del cociente de verosimilitudes medido sobre los datos de entrenamiento. También se describen procedimientos para la aplicación de estos modelos optimizados a otros problemas de aprendizaje como análisis de componentes independientes y clasifiación de Parzen. Junto a los métodos propuestos...

En muchas aplicaciones, se asume un modelo de generación de las observaciones. Cuando se asume también ruido de medida, este modelo crea una función de verosimilitud. Dada unas medidas u observaciones recibidas, entonces en general se conoce la Función de Densidad de Probabilidad (fdp) de las mismas. La inferencia Bayesiana consiste en estimar parámetros de la fdp a posteriori minimizando un coste previamente establecido. El principal inconveniente es que para hallar estos estimadores es necesario, en general, calcular integrales muy complejas, y típicamente en varias dimensiones. En la mayoría de ocasiones esto no es posible de forma analítica. Una alternativa de aproximación estocástica para superar este inconveniente son los métodos MCMC (Markov Chain Monte Carlo) basados en métodos de Monte Carlo. El método MCMC que se estudiar a en este proyecto es el método Metropolis Hastings. El algoritmo Metropolis Hastings genera una serie de muestras a partir de cadenas de Markov que converge hacia la densidad objetivo. La principal limitación de este algoritmo es que la cadena generada puede quedarse atrapada en un sub-región de alta probabilidad de la densidad objetivo, como puede ser una moda, y no representar fielmente la fdp que se desee. Para evitar esto...

Introdução As doenças cardiovasculares (DCV) são a mais importante causa de mortalidade em Portugal, sendo uma área de intervenção que deve ser considerada prioritária. Uma vez instalada a DCV, continua a ser imperioso o controlo dos fatores de risco cardiovascular assim como a adesão à terapêutica, pois na prática verifica-se que os doentes frequentemente mantêm comportamentos de risco cardiovascular. Evidencia-se a pertinência do acompanhamento de enfermagem para fomentar um estilo de vida saudável e a adesão ao regime terapêutico proposto. Objetivo geral: Analisar os efeitos de um programa de prevenção secundária da doença cardiovascular nos doentes a quem foi diagnosticada Síndrome Coronária Aguda (SCA). Objetivo específico: Analisar as diferenças entre os diferentes momentos do programa de ensino sobre a adesão à terapêutica farmacológica.

Introdução e Objectivos A febre na criança é um dos principais motivos de ida aos serviços de urgência pediátrica, quer como único sintoma, quer associado a outras manifestações de doença. Reconhece-se que a abordagem da criança com febre nem sempre é consensual na comunidade científica, particularmente nas vantagens ou desvantagem no processo evolutivo do quadro clínico de uma criança. Devido à existência de ideias erróneas que rodeiam o conceito de febre, bem como ao stress despertado nos pais, estes precipitam-se frequentemente nas medidas a adotar, bem como em acesso eventualemnte precoce aos serviços de urgência. Este estudo teve como objetivos principais: identificar o conhecimento dos pais sobre a febre na criança; e analisar as estratégias utilizadas pelos pais no seu controlo. Metodologia Trata-se de uma RSL (Revisão Sistemática da Literatura). Para a realizarmos procedemos à pesquisa na plataforma EBSCO tendo percorrido as seguintes bases de dados: CINAHL, MEDLINE, MedicLatina, Academic e Search Complete. Foi ainda efetuada pesquisa na base de dados ScieLo. Após rigoroso processo de seleção em que foram estabelecidos previamente vários critérios de inclusão e exclusão, foram retidos 7 artigos que constituíram o corpus documental de análise. Resultados Verificamos que o conhecimento dos pais é em regra insuficiente. Figuejoa et al. (2012) descrevem que mais de metade das mães considera a febre uma doença...
