Abstract:

The purpose of this thesis is to investigate the market potential of producer services in Jönköping County. In relation to the main purpose, the idea is to examine which factors that have a positive impact on the development of a long run qualitative producer service industry in the region.

The favourable location of Jönköping County is one of the main factors for why the county has one of the highest densities of manufacturing firms in Sweden. Moreover, the region has comparative advantages in several products, for an example; wood, rubber, machinery and electronically goods. Earlier research and comparisons with other international manufacturing clusters indicates that these areas tend to contain highly developed producer service industries. The thesis gives a case example of how the beneficial, mutual interaction between the manufacturing and producer service industries works in the car industry in Germany. However, to be able to establish a successful and close relationship between the above mentioned industries, the theoretical framework distinguishes several important factors; for instance, education and infrastructure are assumed to be the two most vital ingredienses. Nonetheless, also the firms’ production milieu and technology affects the successful development of a cluster district. Furthermore,when relating the theoretical assumptions to the descriptive statistics, with the intention to elucidate the industrial structure of Jönköping County, one can differentiate three major producer service sectors, namely; “Transport and mail”, “Consulting, marketing, law” and finally “Rentals of premises, labour and machinery”. Nevertheless, several alarming observations can be noticed concerning the wage level, education intensity, productivity and gross profit percentage within the county’s producer service industry; where all these features are below the domestic average. Nevertheless, the empirical analysis indicates that the region has a varying, but yet a positive market potential in the majority of the county’s municipalities. With correct priorities, Jönköping County has good future prospects to reach a high competitive position, but to accomplish this; the education intensity has to be improved.

Syftet med denna uppsats är att utreda om Jönköpings län besitter marknadspotential inom närindustriella tjänster. I relation till syftet är avsikten också att ta reda på vilka faktorer som kan underlätta utvecklingen av en långsiktig kvalitativ service industri i länet. Den fördelaktiga geografiska positionen är en av faktorerna till varför Jönköpings län har blivit ett av Sveriges industritätaste områden; där regionen har komparativa fördelar i trä, gummi, maskin och elektroniska produkter. Genom tidigare forskning och vid jämförelser med andra internationella tillverkningskluster hävdas det att det finns tydliga tecken på att dessa områden bör innerhålla starkt utvecklade centra för närindustriella tjänster. I uppsatsen nämns framförallt den tyska bilindustrin som ett exempel på hur nära samarbetet mellan tillverkning och service industrin kan bedrivas. För att kunna nå en nära samverkan mellan de nämnda industrierna så pekar teoridelen ut flera viktiga ståndpunkter, där bland annat utbildning och infrastruktur är av allra högsta vikt. Men även företagens produktionsmiljö och teknologi reflekterar hur ett framgångsrikt klusterområde utvecklas. När man därefter relaterar dessa utgångspunkter till den deskriptiva statistiken med syfte att klargöra Jönköpings läns industristruktur, kan man konstatera att den största industritjänsten utgörs av transport och logistik. Därefter följer marknadsföring,redovisning och juridisk rådgivning, medan den tredje och sista tjänsten är uthyrning av lokaler, maskiner och personal. Dock påträffas flera oroväckande iakttagelser gällande lönenivåer, utbildningsintensitet, produktivitet och bruttovinstandelar inom produktionstjänster i länet, då samtliga faktorer hamnar under riksgenomsnittet. Vidare indikerar de empiriska resultaten och analysen på att det finns en varierande men positiv marknadspotential i majoriteten av länets kommuner. Med rätta prioriteringar så finns det således goda framtidsutsikter för att regionen skall kunna skaffa sig en hög konkurrenskraft i framtiden. Men då krävs det framförallt en högre utbildningsgrad bland den arbetsföra befolkningen i länet.

Abstract:

L'obésité abdominale est associée à différents problèmes de santé tels qu’une augmentation du risque de diabète de type 2 et de maladies cardiovasculaires. L’activité physique est un élément clé dans la prise en charge de l’obésité. En effet, elle permet de diminuer le risque cardiométabolique. Peu d’études se sont toutefois intéressées à déterminer la meilleure modalité d’entraînement spécifiquement chez les femmes adultes qui présentent une obésité abdominale. Objectifs : Comparer l’impact de deux modalités d’entraînements cardiovasculaires (entraînement continu d’intensité modérée (MICT) et entraînement par intervalles à haute intensité (HIIT)) qui procurent la même dépense énergétique sur le profil de risque cardiométabolique de femmes caractérisées par la présence d’obésité abdominale. Méthodes : Vingt femmes avec obésité abdominale ont été randomisées en deux groupes. Ainsi, 10 femmes (41,8 ± 8,9 ans) ont pris part au groupe MICT et 10 femmes (37,8 ± 5,7 ans), au groupe HIIT. Elles devaient s’entraîner 3 fois par semaine durant 12 semaines et les entraînements n’étaient pas supervisés. Les données physiques et métaboliques ont été recueillies au début et à la fin du programme. Un test-t de Student pour données appariées a été réalisé afin de comparer la moyenne des données au temps 1 et au temps 2 pour chacun des groupes. Les changements entre les deux groupes ont été comparés à l’aide d’un test-t de Student pour données non appariées. Les données recueillies sont des données préliminaires, car l’étude est toujours en cours. Résultats : L’intervention MICT et HIIT n’a entraîné aucune amélioration significative de la VO₂max. Aucune différence significative n’a été constatée suite à l’intervention dans les facteurs de risque cardiométaboliques, et ce, à la fois pour le groupe MICT et le groupe HIIT. Finalement, il n’y a aucune différence significative entre les deux groupes concernant les changements, et ce, pour tous les paramètres étudiés. Conclusions : Nos données préliminaires démontrent que le MICT et le HIIT n’ont provoqué aucun changement significatif, et ce, à la fois au niveau de la condition physique ou du profil de risque cardiométabolique.
Abdominal obesity is associated with various health problems such as an increased risk of type 2 diabetes and cardiovascular disease. Physical activity is a key element in the management of obesity as it reduces the cardiometabolic risk. Few studies have, however, been interested in determining the best training modality specifically for adult women having abdominal obesity. Objectives: To compare the impact of two cardiovascular training methods (continuous moderate intensity training(MICT) and high intensity interval training (HIIT)) which provide the same energy expenditure on the cardiometabolic risk profile of women characterized by the presence of abdominal obesity. Methods: A total of 20 women with abdominal obesity were randomized into two groups.Thus, 10 women (41.8 ± 8.9 years) took part in the MICT group and 10 women (37.8 ± 5.7 years) in the HIIT group. They had to train 3 times a week for 12 weeks and the training sessions were not supervised. Physical and metabolic data were collected at the beginning and end of the program. A Student's t-test for paired data was performed in order to compare the mean of the data at time 1 and at time 2 for each group. Changes between the two groups were compared using a Student t-test for unpaired data. The data collected is preliminary data as the study is still ongoing. Results: No significant change in VO₂max were observed following the intervention in the MICT and HIIT groups. Following the intervention, no significant difference was found in the cardiometabolic risk factors for the MICT and HIIT groups. Finally, there is no significant difference between the two groups regarding changes for all parameters studied. Conclusions: Our preliminary data shows that MICT and HIIT interventions were not associated with significant improvements inVO₂max or in cardiometabolic risk profile.

Abstract:

Une particularité importante du logiciel est sa capacité à être adapté et configuré selon différents scénarios. Récemment, la variabilité du logiciel a été étudiée comme un concept de première classe dans différents domaines allant des lignes de produits logiciels aux systèmes ubiquitaires. La variabilité est la capacité d'un produit logiciel à varier en fonction de différentes circonstances. Les systèmes à forte variabilité mettent en jeu des produits logiciels où la gestion de la variabilité est une activité d'ingénierie prédominante. Les diverses parties de ces systèmes sont couramment modélisées en utilisant des formes différentes de ''modèle de variabilité'', qui est un formalisme de modélisation couramment utilisé. Les modèles de caractéristiques (feature models) ont été introduits par Kang et al. en 1990 et sont une représentation compacte d'un ensemble de configurations pour un système à forte variabilité. Le grand nombre de configurations d'un modèle de caractéristiques ne permet pas une analyse manuelle. De fait, les mécanismes assistés par ordinateur sont apparus comme une solution pour extraire des informations utiles à partir de modèles de caractéristiques. Ce processus d'extraction d'information à partir de modèles de caractéristiques est appelé dans la littérature scientifique ''analyse automatisée de modèles de caractéristiques'' et a été l'un des principaux domaines de recherche ces dernières années. Plus de trente opérations d'analyse ont été proposées durant cette période. Dans cette thèse, nous avons identifié différentes questions ouvertes dans le domaine de l'analyse automatisée et nous avons considéré plusieurs axes de recherche. Poussés par des scénarios du monde réel (e.g., la téléphonie mobile ou la vidéo protection), nous avons contribué à appliquer, adapter ou étendre des opérations d'analyse automatisée pour l’évolution, le test et la configuration de systèmes à forte variabilité
The large number of configurations that a feature model can encode makes the manual analysis of feature models an error prone and costly task. Then, computer-aided mechanisms appeared as a solution to extract useful information from feature models. This process of extracting information from feature models is known as ''Automated Analysis of Feature models'' that has been one of the main areas of research in the last years where more than thirty analysis operations have been proposed. In this dissertation we looked for different tendencies in the automated analysis field and found several research opportunities. Driven by real-world scenarios such as smart phone or videosurveillance domains, we contributed applying, adapting or extending automated analysis operations in variability intensive systems evolution, testing and configuration

Abstract:

This paper studied the extensive margin (EM) and intensive margin (IM)of liquefied natural gas(LNG) imports in Europe over the period 1996-2015. Two econometric models were used, a prob it estimation for the EM and an OLS for the IM. A time-varying approach was conducted to analyse the stability of the models in the studied time frame. The models were constructed through the application of known determinants of LNG trade as well as new factors that previously was unused in the investigation of LNG trade. The results indicated an overall stable EM, but a highly varying IM over the period. The findings inform that the EM is driven by income, diversification and lower bounds technological development and we found that itis inhibited by pipeline imports, domestic production and higher bounds technological development. The IM is determined by favourable pricing opportunities, lower bounds technological development and the diversification aspect of LNG. IM is negatively affected by domestic natural gas production and the higher bounds of technological development.

Abstract:

Mestrado em Biomedicina Molecular
Physical inactivity is a major risk for obesity. This chronic disease results from a caloric imbalance causing an enlargement of adipocytes by excessive fat storage. With an increasing prevalence, childhood obesity is correlated with endothelial dysfunction, inflammation and oxidative stress conducting to the development of other diseases not only in children but also during adulthood. In other hand, numerous children practice exercise of high duration or intensity in high competition sports, which can have harmful effects at physical, physiological and psychological level. In high competition young athletes, oxidative stress and immunosuppression can happen leading to an elevated risk of infection. However, an improved lipid profile is found in childhood athletes. Thus, the objective of the present study was to analyze the impact of childhood obesity as well as intense swimming training in body composition, inflammation and lipid profile, through blood analysis, bioimpedance and immunodetection of the pro-inflammatory cytokines (IL-6 and TWEAK), a myokine (Myostatin) and an acute-phase protein (CRP). For that, 24 young people were recruited into three groups: obese, athlete and lean. The obese group had high levels of body fat, an atypical lipid profile (low HDL and high LDL), high levels of lactate dehydrogenase in the blood indicating tissue damage, chronic inflammation (high IL-6, CRP and TWEAK) and low muscle mass (high Myostatin) without muscle damage (low CK). However, low serum levels of hepatic enzyme (AST and ALT) in these obese children do not associate obesity with liver disease. In other hand, intense physical exercise is not a harmfull activity for young athletes, since the lipid profile is improved and the increased levels of inflammatory markers is not significant. The main benefit of intensive training is the decreased levels of glucose being a protective role for diabetes.
A inatividade física é um dos principais riscos para a obesidade. Esta doença crónica resulta de um desiquilíbrio calórico causando um alargamento dos adipócitos através do excesso de armazenamento de gordura. Com um aumento da prevalência, a obesidade infantil correlaciona-se com a disfunção endotelial, inflamação e stress oxidativo, conduzindo ao desenvolvimento de outras doenças não só em criança, mas também durante a idade adulta. Por outro lado, muitas crianças praticam exercício de elevada duração ou intensidade em desportos de alta competição, o que pode ter efeitos prejudiciais a nível físico, fisiológico e psicológico. Em jovens atletas de alta competição, stress oxidativo e imunossupressão podem ocorrer levando ao elavado risco de infeção. No entanto, perfis lipídicos melhorados são encontrados em crianças atletas. Desta forma, o objetivo do presente estudo foi analizar o impacto da obesidade infantil bem como de treinos intensivos de natação na composição corporal, inflamação e perfil lipídico através de análises ao sangue, bioimpedância e imunodeteção de citocinas pró-inflamatórias (IL-6 e TWEAK), uma miocina (Miostatina) e uma proteina de fase aguda (CRP). Para tal, foram recrutados 24 jovens divididos em três grupos: obesos, atletas e normoponderais. O grupo de obesos apresentou elevados níveis de gordura corporal, um perfil lipídico atípico (baixo HDL e elevado LDL), níveis elevados de lactato desidrogenase no sangue indicando dano tecidual, inflamação crónica (elevado IL-6, CRP e TWEAK) e massa muscular diminuida (elevada Miostatina) sem dano muscular (baixo CK). No entanto os baixos níveis de enzimas hepáticas (AST e ALT) no soro não associam a obesidade com doença hepática. Por outro lado, o exercício físico intenso não é uma atividade prejudicial para os jovens atletas, uma vez que o perfil lipídico é melhorado e o aumento dos níveis de marcadores inflamatórios não é significativo. O principal benefício do treino intensivo é a diminuição dos níveis de glucose tendo um papel protetor para a diabetes.

Abstract:

The objective of this study is to characterize the hospitalizations that occurred in the Pediatric Intensive Care Unit (PICU) at Santa Maria University Hospital from 2006 to 2013. It is a retrospective, descriptive and cross-sectional study that evaluated 1805 patients admitted to the PICU by secondary data collection and a database built based on the Inpatient Unit Records Book.The variables considered were: sex, age, origin, cause and outcome hospitalization and length of stay. It was performed a descriptive analysis followed by non-parametric inferential analysis with a 5% significance level. Out of the 1805 patients who were hospitalized during the eight-year study (2006-2013), 56.1% were male, where 42.4% were from the city of Santa Maria and 57.6% from others cities belonging the region that HUSM is the reference (4th Health Regional Coordination) or from other locations inside Rio Grande do Sul. There was no significant difference in the number of hospitalizations related to the months or the year. The average length of stay in the PICU was 7.5 days. Most patients (41.6%) were under one old, being the most frequent age of two months. The total mortality rate was 14.3% and 85.7% of the patients discharged from the unit. There was no significant difference between mortality rate and the evaluated year (minimum of 11% in 2012 and maximum of 17.7% in 2009) and age group. The most frequent causes of hospitalization were pneumonia, abdominal postoperative, trauma and sepsis wherein mortality for sepsis was significantly higher than mortality for abdominal postoperative and trauma, but there was no difference from the mortality caused by pneumonia. The data obtained is very similar to the data from others Brazilian PICU. The knowledge of epidemiological profile of patients at PICU of HUSM, still unpublished, can contribute to the decision-making and improve the quality of the care provided to users. In addition, the use of such data through appropriate analysis, dissemination and development of protocols and practices for the team, can also contribute to subsidy future studies, as well as provide guidance for patient care.
O objetivo desde estudo é caracterizar as internações que ocorreram na Unidade de Terapia Intensiva Pediátrica (UTIP) do Hospital Universitário de Santa Maria (HUSM) de 2006 a 2013. Constitui um estudo retrospectivo, descritivo, transversal, onde se avaliou, mediante dados secundários, 1805 internações neste período. As variáveis consideradas foram: sexo, idade, procedência, desfecho da internação, tempo de internação e causa. Foi realizada a análise descritiva seguida da análise inferencial não paramétrica com nível de significância de 5%. Das 1805 internações a maioria (56,1%), foi do sexo masculino, sendo que 42,4% eram da cidade de Santa Maria e 57,6% da região à qual o HUSM é referência (4ª Coordenadoria Regional de Saúde) ou de outro local do Estado do Rio Grande do Sul. Não houve diferença significativa em relação ao número de internações mensais e entre o número de internações anuais. O tempo médio de permanência na UTIP foi de 7,5 dias. A maioria dos pacientes (41,6%) tinha até um ano de idade, sendo a idade mais frequente de dois meses. A mortalidade encontrada foi de 14,3%, ou seja, 85,7% tiveram alta da unidade. Não houve diferença significativa entre a mortalidade entre os anos avaliados (mínimo de 11% em 2012 e máximo de 17,7% em 2009) e entre as faixas etárias. As causas de internação mais frequentes foram: pneumonia, pós-operatório abdominal, trauma e sepse, sendo que a mortalidade por sepse foi significativamente maior do que por pós-operatório abdominal e por trauma, mas não diferiu da mortalidade por pneumonia. Considerando as características de cada local, os dados encontrados se assemelham aos de outras UTIP no Brasil. O conhecimento dos resultados deste serviço, ainda inéditos, pode contribuir para a tomada de decisões, melhoria na assistência prestada aos usuários, qualificação do serviço e facilidade no acesso às informações. Além disso, o uso desses dados, por meio da análise adequada, divulgação, elaboração de protocolos e condutas para a equipe, podem contribuir para subsidiar estudos futuros, bem como orientar políticas de atendimento e cuidados aos pacientes.

Abstract:

Much of the aerosol research completed at the University of South Florida has revolved around evaluating industrial hygiene equipment and instrumentation in environmental chambers. Data collected during these studies has provided valuable baseline data on equipment and instrument performance under calm air conditions. A newly constructed wind tunnel now allows researchers to evaluate industrial hygiene instruments under moving air conditions. Because the wind tunnel is capable of producing wind velocities that a worker could encounter in the occupational setting, researchers may gain insight into instrument performance under simulated field conditions. Because aerosols can be introduced into the new wind tunnel testing section, researchers can also challenge industrial hygiene equipment and instrumentation with aerosols in sizes ranges that are of interest in public health. The purpose of this dissertation research was to develop a new wind tunnel to be used for aerosol research at the University of South Florida. Three specific aims had to be met for this study to be successful. They included: (1) designing a wind tunnel based on best practice information outlined in scientific literature, (2) constructing an operable wind tunnel to be used for aerosol research, and (3) characterizing wind tunnel performance by examining the wind tunnel velocity profile, turbulence intensity, and aerosol introduction/collection. The actual wind tunnel was constructed to a length of approximately 20 feet, a height of approximately 2 feet at its tallest point, and includes an entrance filter housing, a settling chamber, a contraction, a testing section, a diffuser, an exit filter housing, a fan, and exhaust duct. All components were designed and constructed using guidelines and best practices reported in the scientific literature. Velocity profile measurements were the first way that this wind tunnel was characterized. In order to successfully obtain measurements, the wind tunnel cross section was divided into 16 equal quadrants. Five measurements were taken for each quadrant at each wind velocity. Target wind velocities for this research were 0.5 m/s, 1.0 m/s, and 2.0 m/s. Actual average wind velocities of 0.48 m/s, 1.00 m/s, and 2.04 m/s. All were within established limits reported in the scientific literature. Turbulence intensity measurements were the second way that this wind tunnel was characterized. In order to successfully obtain measurements, the wind tunnel cross section was divided into 16 equal quadrants. Five measurements were taken for each quadrant at each wind velocity. Wind tunnels are typically designed to have the lowest turbulence intensity possible, generally below 10%. The overall average turbulence intensities for this wind tunnel at wind velocities of 0.5 m/s, 1.0 m/s, and 2.0 m/s were 9%, 10%, and 8% respectively. Overall turbulence intensity measurements were at or below 10%. Isokinetic sampling was the final method used to characterize this wind tunnel by collecting and detecting aerosols traveling through the wind tunnel testing section. The wind tunnel was operated at wind velocities of 0.5 m/s, 1.0 m/s, and 2.0 m/s with isokinetic sampling flow rates of 15.4 L/min, 30.9 L/min, and 61.7 L/min respectively. Monodisperse fluorescent polystyrene latex spheres were used as the test aerosol because they are uniform in size and shape and can be detected by fluorometry. The Blaustein Multi-Jet Atomizer (BLAM) was used to generate monodisperse fluorescent polystyrene latex aerosol 0.5 µm and 2.0 µm particles from liquid suspensions. The Vilnius Aerosol Generator (VAG) was used to generate monodisperse fluorescent polystyrene latex aerosol of 6.0 µm and 12.0 µm particles from dry powders. Nitrogen gas was used for delivering test aerosols into the wind tunnel. Five experimental runs were completed for each particle size and wind velocity for a total of 60 experimental runs. Fluorescence was detected in all 60 samples with average mass concentrations ranging from 0.000050 ng/ml to 0.002703 ng/ml. Based on velocity profile measurements, turbulence intensity measurements, and isokinetic sampling, the performance of University of South Florida wind tunnel was found to be excellent, indicating that it was designed and constructed appropriately. The wind tunnel can now successfully be used by researchers interested in evaluating industrial hygiene sampling equipment with aerosols ranging from 0.5 µm to 12.0 µm in moving air with velocities ranging from 0.5 m/s to 2.0 m/s.

Abstract:

Better understanding of the role of vegetation in the transport of fluid and pollutants requires improved knowledge of the detailed flow structure within the vegetation. Instead of spatial averaging, this study uses discrete measurements at multiple locations within the canopy to develop velocity and turbulence intensity profiles and observe the changes in the flow characteristics as water travels through a vegetation array simulated by rigid dowels. Velocity data were collected with a one dimensional laser Doppler velocimeter (LDV) under single layer emergent and submerged flow conditions, and through two layers of vegetation. The effects of dowel arrangement, density, and roughness are also examined under the single layer experiments. The results show that the velocity within the vegetation array is constant with depth and the velocity profile is logarithmic above it. The region immediately behind a dowel, where the vorticity and turbulence intensity are highest, is characterized by a velocity spike near the bed and an inflection point near the top of the dowel arrays. With two dowel layers, the velocity profile in the region behind a tall dowel exhibits multiple inflection points and the highest turbulence intensities are found there.

Abstract:

Necrotizing enterocolitis (NEC) is a costly and deadly disease in neonates. Composite risk for NEC is poorly understood and consensus has not been established on the relevance of risk factors. This two-phase study attempted to validate and test a neonatal NEC risk index, GutCheck(NEC). Phase I used an E-Delphi methodology in which experts (n=35) rated the relevance of 64 potential NEC risk factors. Items were retained if they achieved predefined levels of expert consensus or stability. After three rounds, 43 items were retained (CVI=.77). Qualitative analysis revealed two broad themes: individual characteristics of vulnerability and the impact of contextual variation within the NICU on NEC risk. In Phase II, the predictive validity of GutCheck(NEC) was evaluated using a sample from the Pediatrix BabySteps Clinical Data Warehouse (CDW). The sample included infants born<1500 grams, before 36 weeks, and without congenital anomalies or spontaneous intestinal perforation (N=58,818, of which n=35,005 for empiric derivation and n=23,813 for empiric validation). Backward stepwise likelihood-ratio method regression was used to reduce the number of predictive factors in GutCheck(NEC) to 11 and derive empiric weights. Items in the final GutCheck(NEC) were gestational age, history of a transfusion, NICU-specific NEC risk, late onset sepsis, multiple infections, hypotension treated with Inotropic medications, Black or Hispanic race, outborn status, metabolic acidosis, human milk feeding on both day 7 and day 14 (reduces risk) and probiotics (reduces risk).Discrimination was fair in the case-control sample (AUC=.67, 95% CI .61-.73) but better in the validation set (AUC=.76, 95% CI .75-.78) and best for surgical NEC (AUC=.84, 95% CI .82-.84) and infants who died from NEC (AUC=.83, 95% CI .81-.85). A GutCheck(NEC) score of 33 (range 0-58) yielded a sensitivity of .78 and a specificity of .74 in the validation set. Intra-individual reliability was acceptable (ICC (19) =.97, p<.001). Future research is needed to repeat this procedure in infants between 1500 and 2500 grams, complete psychometric testing, and explore unit variation in NEC rates using a comprehensive approach.

Abstract:

Yes
When using point measurement for environmental or sediment laden flows, there is well-recognised risk for not having aligned measurements that causes misinterpretation of the measured velocity data. In reality, these kinds of mismeasurement mainly happen due to the misinterpretation of bed orientation caused by the complexity of its determination in natural flows, especially in bedload laden or rough bed flows. This study proposes a novel bed realignment method to improve the measured data benchmarking by three-dimensional (3D) bed profile orientation and implemented it into different sets of experimental data. More specifically, the effects of realignment on velocity profile and streamwise turbulence structure measurements were investigated. The proposed technique was tested against experimental data collected over a water-worked and an experimentally arranged well-packed beds. Different from the well-packed rough bed, the water-worked bed has been generated after long sediment transport and settling and hence can be used to verify the proposed bed-alignment technique thoroughly. During the flow analysis, the corrected velocity, turbulence intensity and Reynolds stress profiles were compared to the theoretical logarithmic law, exponential law and linear gravity (universal Reynolds stress distribution) profiles, respectively. It has been observed that the proposed method has improved the agreement of the measured velocity and turbulence structure data with their actual theoretical profiles, particularly in the near-bed region (where the ratio of the flow measurement vertical distance to the total water depth, z/h, is limited to ≤0.4).

Abstract:

Gallium nitride (GaN)-based light-emitting diodes (LEDs) with cylindrical nanostructures have been the subject of significant research interest in the past decade, due to the potential of such structures to increase light extraction efficiency and deliver highly directional light emission. Nanorod LEDs, where the light emission is within the nanocylinder, have the additional potential to increase internal quantum efficiency and emit in colours previously thought impractical with GaN-based LEDs. Optical modelling of nanostructured LEDs is usually carried out using finite-difference time-domain methods, which are computationally intensive and do not always provide sufficient insight into the physics underlying the simulation results. This thesis proposes an intuitive, quasi-analytic method based on modal expansion. It is found that it is possible to calculate the far field diffraction patterns of all guided modes supported by a single nanorod, with full consideration of Fabry-Perot effects, in minutes using a standard office desktop computer. Focus is placed on the case of a nanorod of radius 140 nm, for which angular photoluminescence measurements were available to provide a means of validating the model. Consideration of the guided modes alone provides a compelling explanation for gross features in the measured data where none previously existed. It is shown that, using a standard equation from a textbook, it is possible to calculate how much each of the guided and radiation modes of a single nanorod is excited by a Hertzian dipole of known position and orientation with respect to the nanorod geometry. When interference between these modes is considered, it is possible to calculate the total far field angular emission pattern due to that dipole. Comparing these patterns with photoluminescence measurements allows one to infer the locations and orientations of dipole current sources; the results are found to be consistent with those of cathodoluminescence studies.

Esta dissertação propõe-se a modelar a dinâmica da exclusão social ao investigar as características dos indivíduos que contribuem para aumentar a probabilidade deste se encontrar em situação de exclusão social, assim como identificar os grupos mais vulneráveis. Para o efeito, vamos usar o critério proposto pelo Eurostat para definir a exclusão social, usando uma base de dados longitudinal de quatro anos do ICOR (Inquérito para as Condições de Vida e Rendimento) relativa à população portuguesa. O critério é traduzido num indicador binário de exclusão social, assim sendo, recorremos aos modelos Pooled Probit e Probit de Efeitos Aleatórios para modelar os nossos dados. Este trabalho tem também como objetivo enriquecer a literatura existente acerca desta matéria, e possibilitou-nos alcançar resultados interessantes, relativos às características que ajudam a explicar a probabilidade de ocorrência de exclusão social e aos grupos que se mostram mais vulneráveis a este problema.
This dissertation intends to model the dynamics of social exclusion by investigating the individual characteristics that contributes to increase the probability of being socially excluded, as well as the identification of the most vulnerable population groups. We will be using the criteria proposed by the Eurostat to define social exclusion, and we will be using a four years longitudinal data from European Statistics on Income and Living Conditions relative to the Portuguese population. We aggregate the criteria into a binary indicator of social exclusion, so we will be applying a Pooled Probit and a Random Effects Probit model to the data. This work also intends to enrich the literature about this subject, as we were able to reach interesting results, relative to the determinants of social exclusion and some of the most vulnerable groups to this phenomenon.

A subject that has aroused considerable interest in hydrometeorology and hydrology is the establishment of standards Rainstorm focusing on the positioning of the peaks over the duration of the events. We used rainfall data obtained in PCD located in the city of Barreiros in Meso coast of the state of Pernambuco, the period from 01/06/2000 (date of installation of PCD) to 31/12/2010. The methodology identified, besides the already known and referenced standards Advanced, Intermediate and Retarded, the following: Undefined and Multipico. Moreover, through the confrontation of heavy rainfall events identified with the stationary satellite images, the standards set were related to meteorological factors responsible and determinants thereof, giving bigger and better elements for aggregation of advantages in the provision of mitigation measures effects of weather forecasts and conditions within the modern view of weather. Therefore, the aim of this study was to indicate a form of rational presentation and unpublished patterns of heavy rainfall, providing subsidies to redirect the studies, with equanimity, and in accordance with the objectives which they propose, and additionally relate the patterns to weather systems that originate.
Um assunto que tem despertado bastante interesse na hidrometeorologia e hidrologia é o estabelecimento de padrões de chuvas intensas com enfoque no posicionamento dos picos ao longo da duração dos eventos. Foram usados os dados de precipitação obtidos na PCD localizada no município de Barreiros, na Mesorregião Litoral do Estado de Pernambuco, compreendendo o período de 01/06/2000 (data de instalação da PCD) a 31/12/2010. A metodologia aplicada permitiu identificar, além dos já conhecidos e referenciados padrões Avançado, Intermediário e Retardado, os seguintes: Indefinido e Multipico. Ademais, mediante a confrontação dos eventos de chuvas intensas identificados com as imagens fornecidas por satélites estacionários, os padrões estabelecidos foram relacionados com os fatores meteorológicos responsáveis e determinantes dos mesmos, conferindo maiores e melhores elementos para agregação de vantagens na provisão de medidas de mitigação dos efeitos e condições de previsões dentro da visão moderna de clima. Portanto, o objetivo do presente trabalho foi indicar uma forma de apresentação racional e inédita, dos padrões de chuvas intensas, proporcionando subsídios ao redirecionamento dos estudos, com equanimidade, e de conformidade com os objetivos a que se propõem, e, adicionalmente, relacionar os padrões aos sistemas meteorológicos que os originam.

Abstract:

Dans ce travail, nous avons etudie certains aspects du mecanisme de la luminescence du silicium poreux. La particularite de l'approche a ete le suivi simultane de l'intensite, des temps de vie et de la forme du declin de la pl en fonction des plusieurs parametres tels que: la temperature, le niveau d'oxydation anodique et l'intensite d'excitation. Nous decrivons la structure poreuse comme un ensemble de cristallites de dimensions nanometriques, interconnectees par des ponts de silicium ou de silice. Le premier niveau excite dans ces cristallites est localise, les porteurs se retrouvant confines dans un point quantique. Par contre, les niveaux excites superieurs sont etendus sur plusieurs cristallites, les porteurs etant confines dans un fil quantique. Pour des temperatures plus petites que 250k, nous avons conclu que les porteurs sont localises et une description de la dynamique de recombinaison limitee par l'effet tunnel est valable dans toute cette gamme des temperatures. A plus hautes temperatures, le changement de la forme du declin et la forte decroissance de l'intensite de la pl ont ete associes a une delocalisation progressive des porteurs par activation thermique. Dans ce cadre, l'evolution contraire, enregistree au cours de l'oxydation anodique du silicium poreux, est assimilee a une localisation progressive des porteurs par l'accroissement des barrieres de potentiel du a l'oxydation des ponts reliant les cristallites. Le dernier volet de ce travail comporte une etude de l'evolution de l'intensite de la pl en fonction de l'intensite d'excitation. La saturation de la pl, detectee dans un regime de fortes intensites d'excitation, a ete attribuee a une intensification de la recombinaison auger. La meme explication est ensuite utilisee pour justifier la diminution du rendement de luminescence dans un regime de forte injection electrique

Conjugated linoleic acid (CLA), a fatty acid (FA) present in the meat and milk of ruminant animals, is considered a functional nutrient for humans. The interest in CLA is attributed to its many health benefits, such as having anti-carcinogenic, anti-atherogenic, anti-diabetic and anti-adipogenic effects. Dairy products are a rich natural source of CLA, and preliminary research indicates that the levels in milk can vary based on cattle breed and feeding system. The Fleckvieh is a popular dual-purpose breed recently introduced to the Western Cape. It is used in crossbreeding programs with Holstein and Jersey herds to increase fertility and beef production. Holstein and Jersey cattle are the two most common South African dairy breeds, but little information is available on the effect of crossbreeding on FA content and CLA levels in the milk. The primary objective of this study was to compare milk FA composition and CLA content of these two dairy breeds and their respective Fleckvieh crosses. A second objective was to investigate the effect of lactation stage on CLA levels. Jersey (J) and Fleckvieh x Jersey (F×J) cows were kept in a pasture-based system (PBS) for the duration of the study. Holstein (H) and Fleckvieh x Holstein (F×H) cows were housed in a feedlot system and fed a total mixed ration (TMR) for the duration of the study. The FA and CLA content of feeds from these two feeding systems were also analysed and compared. All cows used in the study were housed at the Elsenburg Research Farm of the Western Cape Department of Agriculture. Milk samples were collected every 35 days from the cows in each feeding group, starting 10 days after calving. Samples were kept in a freezer at -20 °C until laboratory analyses. The total number of milk samples collected was 1044. The milk FA composition and CLA in particular were determined by gas chromatography. Differences between groups were statistically analysed by two-way repeated measures of analysis of variance (ANOVA). Results show that milk CLA levels are higher in Fleckvieh-crossbred cows when compared to purebred cows. The higher CLA content of milk from Fleckvieh crossbred cows demonstrates the feasibility of using Fleckvieh bulls in South African crossbreeding programs, and are also an indication that genetic selection for increased CLA content is possible. The analysis of lactation stage showed that milk CLA is higher during late lactation. A comparison of feed samples from the two feeding systems revealed that pasture feeding resulted in higher omega-3 FA in milk.

Abstract:

Wind power, especially offshore, is considered to be one of the most promising sources of ‘clean’ energy towards meeting the EU targets for 2020 and 2050. However, its popularity has always fluctuated with the price of fossil fuels since nowadays wind electricity production cannot compete with nuclear or coal electricity production. Support structures are thought to be one of the main drivers for reducing costs in order to make the wind industry more economically efficient. Foundations and towers should be fit for purpose, extending their effective service life but avoiding costs of oversizing. An exhaustive review of the background and state of the art of the Fatigue-Life assessment approaches has been carried out, combining analysis of the gathered experimental data and the development of Finite Element models based on contemporary 3D solid models with diverse Regression Analyses, in order to identify their weakness and evaluate their accuracy. This research shows that the guides and practices currently employed in the design and during the operation of the offshore wind turbine support structures are obsolete and not useful for optimisation, which generally leads to conservationism and an unnecessary increase in costs. The basis for a comprehensive update of the Girth Weld and Tubular Joint S-N curves and the Stress Concentration Factors of Tubular Joints has been set out. Furthermore, a reliable methodology for deriving the Stress Intensity Factor at the deepest point of a semi-elliptical surface saddle crack in a tubular welded T-joint has been proposed.

Full text

Abstract:

Les pollutions par les xénobiotiques, en particulier les pesticides, et les métaux lourds issus des activités agricoles présentent une grande complexité de composition chimique et de dynamique spatio-temporelle. La présence de bandes enherbées entre les parcelles cultivées et les cours d’eau permet une limitation de la diffusion de ces pollutions résiduelles vers les milieux naturels. Le compartiment végétal de ces bandes enherbées peut jouer de multiples rôles dans ce contexte de protection environnementale. L’étude comparative réalisée in situ et en conditions contrôlées de laboratoire a permis de mettre en évidence le rôle biologique du compartiment végétal avec son implication directe dans les processus in planta d’absorption, de stockage et/ou de dégradation au moins partielle. Un tel rôle phytoremédiateur est dépendant de la capacité des plantes à se maintenir sur ces milieux pollués, qui diffère selon l’espèce considérée et structure ainsi les communautés végétales des bandes enherbées. L’étude intégrative en conditions contrôlées des réponses des plantes aux interactions avec les xénobiotiques à faibles doses, à différentes échelles de complexité du fonctionnement végétal, a permis de montrer les effets de ces stress chimiques chez l’espèce modèle Arabidopsis thaliana et chez l’espèce prairiale Lolium perenne. Les xénobiotiques et les métaux lourds à des doses subtoxiques ont induit d’importants bouleversements métabolomiques et moléculaires chez ces espèces, avec des effets cryptiques de ces polluants et de leurs produits de dégradation. L’analyse en conditions de multi-pollution, qui reflètent de manière réaliste les pollutions péri-agricoles, a montré la complexité et la difficulté de prédiction des interactions entre les effets des contaminants en mélange. Ces mécanismes de réponses diffèrent selon l’espèce et le polluant et laissent supposer des divergences en termes de perception et/ou de transport des polluants, ou de coordination des réponses moléculaires et métaboliques. Arabidopsis a ainsi présenté une coordination de ses réponses orientée vers une augmentation des métabolites de stress, et une diminution des métabolites carbonés (sucres solubles), en parallèle de modifications de l’expression de gènes impliqués dans les défenses antioxydantes, les défenses contre les stress xénobiotiques, ou dans la dynamique des phytohormones. Le stress chimique a entraîné chez Lolium des modifications majeures du métabolisme azoté, ainsi qu’un remaniement des processus de photorespiration. L’analyse transcriptomique de cette espèce a de plus montré que la majorité des gènes identifiés sont impliqués dans des voies de transduction de signal, montrant ainsi la complexité des mécanismes de réponse et les couplages qui existent entre les signaux métaboliques, en particulier liés aux sucres, les voies de signalisation associées aux phytohormones, les signaux de stress et la photosynthèse
Environmental pollutions by xenobiotics, especially by pesticides and heavy metals derived from agricultural activities, show an important complexity of chemical composition and of spatiotemporal dynamic. Vegetative filter strips between cultivated fields and streams limit the diffusion of these residual pollutions to natural environments. However, the exact biological role of plant in these buffer strips is poorly understood in this context of environmental and ecological protection. A comparative study carried out in situ and in controlled conditions highlighted the role of plant compartment in the processes of absorption, storage and/or partial degradation of pollutants in planta. Such capability of phytoremediation depends on the maintenance of a vegetal cover in area subjected to recurring flow of pesticides, it varies according to species and leads to the structuration of vegetative filter strip communities. An integrative study in controlled conditions of plant responses to low doses of pollutants allowed to analyze at different levels of complexity the impacts of chemical stresses on the model species Arabidopsis thaliana and the grassland species Lolium perenne. Low and sublethal doses of xenobiotics, associated degradation products and heavy metals induced cryptic perturbations at metabolic and molecular levels. Multi-pollution analyses, which reflect realistic conditions of environmental exposure, highlighted complex interactive effects between pollutants in mixture and the difficulty to predict them. The mechanisms of response to these chemical stresses differ according to the species and the pollutant, and suggest differences in term of perception and/or transport of pollutants, or of coordination of molecular and metabolic responses. Arabidopsis presented a coordination of its responses toward an increase of stress metabolites, a decrease of carbon metabolites (soluble carbohydrates), in parallel with modifications of gene expressions implicated on antioxidant defences, defence against xenobiotic stresses, or phytohormone dynamic. Chemical stress leads to major modifications of nitrogen metabolism in Lolium, and perturbations of processes of photorespiration. De novo transcriptomic analysis of Lolium therefore showed that a majority of identified genes are related to signal transduction pathways, highlighting the complexity of response mechanisms and the links between metabolic signals, especially linked to carbohydrate, hormonal signaling pathways, stress signals and photosynthesis. Subtoxic chemical stress induced cryptic re-engineering of plant processes that may explain the development of tolerance for some species and their persistence in area affected by residual pollution

The profile of the Brazilian cattle industry has changed due to the search for more efficiency. It is transforming form extractive practices to new levels of intensification and productivity. In this context, the metabolic and parasitological profile of 39 crossbred animals, aged around 24 months at the time of entering the feedlot and prior to slaughter were performed, in order to assess the health of bovine finished in this breeding system. The following evaluations were carried out: hematology, biochemistry, histopathology and parasitology. The clinical biochemical evaluation consisted of the higidity assessment of the liver and kidney, comprising the balance of energy and protein of these animals. The parameters used were: ALP, AST, GGT, bilirubin (total, conjugated and unconjugated), total protein, albumin, globulin, urea, creatinine, cholesterol and triglycerides. Total proteins were fractionated by agarose gel electrophoresis. Parasitological assessment was done through EPG and stool culture. In histopathology fragments of liver, kidney, lynph nodes (mesenteric, pre scapular and pre femoral) and lung were observed. Alterations in biochemical and electrophoretic tests, suggestive of chronic liver disease, were found. Such alterations were noticed by the presence of foamy macrophages in the liver and mesenteric lymph nodes; however, these findings were not related to differences found in daily weight gain found. Histology did not show alterations suggestive of respiratory diseases.
Com a busca por eficiência produtiva, o perfil da pecuária brasileira tem mudado; deixando de ser um empreendimento extrativista e tornando-se capaz de atingir, cada vez mais, novos patamares no caminho da intensificação, aumentando a produtividade. Neste contexto foi realizada a avaliação do perfil metabólico e parasitológico de 39 bovinos, mestiços de corte, com idade em torno de 24 meses, no momento de entrada no confinamento e anterior ao abate, no intuito de avaliar a saúde dos animais terminados neste sistema de criação. As avaliações realizadas foram: hematologia, bioquímica sérica, histopatológica e parasitológica. A bioquímica sérica consistiu na avaliação da higidez do fígado e do rim, englobando o balanceamento energético e protéico destes animais. Os parâmetros utilizados foram: ALP, AST, GGT, bilirrubina (total, direta e indireta), proteína total, albumina, globulina, uréia, creatinina, colesterol e triglicérides. As proteínas totais foram fracionadas por meio da eletroforese em gel de agarose. A avaliação parasitológica foi realizada por meio do OPG e da coprocultura. Nos exames histopatológicos foram colhidos, processados e observados fragmentos de fígado, rim, linfonodo (mesentérico, pré-escapular e pré-crural) e pulmão. Foram encontradas alterações nos exames bioquímicos e eletroforéticos sugestivos de doença hepática crônica, que foram constatadas com a presença de macrófagos espumosos no fígado e no linfonodo mesentérico, porém estes achados não foram relacionados as diferenças no ganho de peso médio diário encontrada. Na avaliação histológica não foi observada alteração sugestivas de doenças respiratórias.

Abstract:

The present investigation was mainly motived by some problems encountered in the calculation of atmospheric transmission, which do not succeed in fitting the observed data More specifically, we performed both an experimental investigation and a modeling of the absorption of CO2 ,around the Q branch located at 14 µm, laying stress on the importance of line coupling effects. A tunable diode laser mounting was used, allowing resolution of 1. 10-3 cm-1 or better. This enabled us to measure accurately the individual intensities and widths of lines in this Q branch. Then the absorption profile has been systematicaly measured as a function of pressure, and the departure fom the lorentzien model clearly pointed out. Ln order to account for the observed absorption, we were therefore led to include in the calculation the line-coupling coefficients ( usually disregarded in the Lorentzien model). This requires the calculation of the off-diagonal elements of the diffusion matrix. For this purpose, the only tractable procedure is to use a "scaling-law" approach. The obtained values allowed us to obtain quite excellent agreement with the experiment data
Les problèmes liés au calcul de la transmission spectrale terrestre ont été à l'origine de cette étude : quels que soient les types de modélisation utilisés, ceux-ci butent sur l'impossibilité fondamentale à rendre compte des observations dans certaines des régions spectrales concernées. Ce travail, entrepris à la fois sur un plan expérimental et théorique, a donc consisté à modéliser l'absorption infrarouge de C02 dans la région de 14 µm. Dans cette région, la nécessité de tenir compte des effets d'interférence entre raies a été clairement mise en évidence, notamment dans la zone de la branche "Q" de la transition 10°← 0110 située à 720 cm-1. La technique expérimentale adoptée a été la spectroscopie par diodes laser accordables qui permet d'atteindre des résolutions voisines de 1. 10-3 cm-1. Nous avons ainsi pu mesurer avec précision les intensités et les coefficients d'élargissement des raies de cette branche. Nous avons ensuite effectué une série d'enregistrements pour observer l'évolution du profil d'absorption en fonction de la pression, et mettre en évidence les effets de non-additivité des profils. A partir de ces données expérimentales "haute pression" ainsi que des paramètres individuels de raies précédemment mesurés, un essai de modélisation théorique a été entrepris afin de rendre compte des écarts au profil de Lorentz usuellement adopté dans les modèles de reconstitution des profils spectraux. Cette modélisation requiert le calcul des éléments matriciels non-diagonaux de la matrice représentant l'opérateur de diffusion. Dans l'état actuel de la théorie, un calcul à priori de ces éléments est impraticable. On a donc adopté un modèle du type " loi d'échelle " qui a donné des résultats tout à fait satisfaisants

Abstract:

L’objet de la thèse consiste à analyser la relation entre la consommation d’électricité et le produit intérieur brut dans une démarche d’intelligence économique. Plus précisément il s’agit d’analyser l’évolution de l’intensité électrique de l’activité économique sur la période de 2003 à 2012 dans les pays développés du G7 et estimer leurs demandes électriques entre 2013 et 2022.Une première partie cherche à explorer les aspects théoriques et pratiques de l’intelligence économique afin de la comprendre et l’appliquer. Une deuxième partie est consacrée à l’analyse empirique. Nous sommes parvenus aux résultats suivants :Premièrement, les courbes d’intensité électrique de deux pays : le Canada et le Etats – Unis dominent celles des autres pays développés, ainsi, les économies de ces deux pays de l’Amérique du nord sont plus énergivores que celles du Japon et des pays de l’Union européenne. Ensuite, l’évolution temporelle de la consommation d’électricité par unité de PIB sur dix années (2003 – 2012) a globalement diminué dans cinq pays: le Canada (-12%) ; le Royaume – Uni (-5, 3%) ; les Etats – Unis (-5%) ; la France (- 4%) ; l’Allemagne (-3%). Par contre, elle s’est détériorée au Japon (+5%) et en Italie (+6%). L’effet de « structure » est négatif dans tout l’échantillon, il traduit donc t une tertiarisation généralisée. Par contre l’effet « d’efficacité électrique » est contrasté. Il est négatif au Canada et aux Etats – Unis et positif dans le reste du groupe.Deuxièmement, les estimations indiquent une croissance généralisée de la demande électrique de 2013 - 2022 dans l’ensemble des pays du G7. Par ailleurs, les coefficients élasticité électricité /PIB sont inférieurs à l’unité dans tous les pays, excepté l’Italie. Cela signifie que la demande d’électricité moyen annuel de ces pays devrait croître moins vite que leurs PIB. Enfin, les principales perspectives de recherche qui apparaissent à l'issue de cette thèse concernent la transposition de notre modèle d’analyse (l’intelligence énergétique) aux autres formes d’énergie à savoir : le pétrole, le gaz, le charbon et les renouvelables .Finalement, ce modèle peut servir d’instrument de politique économique, énergétique et environnementale aux acteurs économiques et politiques (Etats, entreprises, ONG, OIG.)
The subject of this thesis consists of an analysis of the relationship between electricity consumption and Gross Domestic Product from the perspective of Competitive Intelligence. More specifically, it analyzes the evolution of the electrical intensity of economic activity from 2003 to 2012 in the developed countries of the G7, and then estimates their electricity needs from 2013 to 2022. Part one attempt to explore theoretical and practical aspects of Competitive Intelligence to understand and apply them, while part two is devoted to the empirical analysis itself.Concerning the latter, our results are as follows:First, the electrical intensity curves of two countries—Canada and the United States—dominate those of other developed countries; thus, the economies of these two North American countries are more energy-hungry than those of Japan and the countries of the European Union. The overall temporal evolution of electricity consumption per GDP unit over a ten-year period (2003-1012) has gone down in five countries: Canada (-12%), the United Kingdom (-5.3%), the United States (-5%), France (-4%), and Germany (-3%). On the other hand, this evolution has gone the other direction in Japan (+5%) and Italy (+6%). The effect of “structure” is negative across all analyzed data, suggesting general “tertiarisation”. However, the effect of “electricity efficiency” is mixed: it is negative in the United States and Canada, but positive for the rest of group.Second, estimations indicate an overall growth in electricity demand across all G7 countries from 2013 to 2022. Additionally, electrical elasticity coefficients/GDP units are down in all countries except Italy. This tells us that the average annual demand for electricity in these countries should increase at a slower rate than their respective GDPs.Lastly, the primary research perspectives that appear at the beginning of this thesis concern the transposition of our model of analysis (energetic intelligence) onto other forms of energy such as oil, natural gas, coal, and renewable energy sources. In the end, this model could be useful to economic and political authorities (governments, private companies, NGOs, IGOs, etc.) as an instrument of economic, energy, and environmental policy

Abstract:

Avec l’émergence du calcul haute-performance (HPC) et des applications Big Data, de nouvelles problématiques cruciales sont apparues. Parmi elles on trouve le problème du transfert de données, c’est-à-dire des communications entre machines, qui peut génerer des délais lors de gros calculs en plus d’avoir un impact sur la consommation énergétique. La réplication, que ce soit de tâches ou de fichiers, est un facteur qui accroît ces communications, tout en étant un outil quasi-indispensable pour améliorer le parallélisme du calcul et la résistance aux pannes. Dans cette thèse nous nous intéressons à la réplication de fichiers et à son impact sur les communications au travers de deux problèmes. Dans le premier, la multiplication de matrices en parallèle, le but est de limiter autant que possible ces réplications pour diminuer la quantité de données déplacées. Dans le second, l’ordonnancement de la phase « Map » de MapReduce, il existe une réplication initiale qu’il faut utiliser au mieux afin d’obtenir l’ordonnancement le plus rapide ou entraînant le moins de création de nouvelles copies. En plus de la réplication, nous nous intéressons aussi à la comparaison entre stratégies d’ordonnancement statiques (allocations faites en amont du calcul) et dynamiques (allocations faites pendant le calcul) sur ces deux problèmes avec pour objectif de créer des stratégies hybrides mélangeant les deux aspects. Pour le premier problème, le produit de matrices en parallèle, nous nous ramenons à un problème de partition de carré où l’équilibrage de charge est donné en entrée. Cet équilibrage donné, le but est de minimiser la somme des semi-paramètres des rectangles couvrant des zones ainsi créés. Ce problème a déjà été étudié par le passé et nous démontrons de nouveaux résultats. Nous proposons ainsi deux nouveaux algorithmes d’approximation, l’un fondé sur une stratégie récursive et l’autre sur l’usage d’une courbe fractale. Nous présentons également une modélisation alternative, fondée sur un problème similaire de partition de cube, dont nous prouvons la NP-complétude tout en fournissant deux algorithmes d’approximation. Pour finir, nous réalisons également une implémentation pratique du produit de matrices en utilisant nos stratégies d’allocation grâce à la librairie StarPU. Les résultats expérimentaux montrent une amélioration du temps de calcul ainsi qu’une diminution significative des transferts de données lorsqu’on utilise une stratégie statique d’allocation couplée à une technique de vol de tâches. Pour le second problème, l’ordonnancement de la phase « Map » de MapReduce, plusieurs copies des fichiers d’entrée sont distribuées parmi les processeurs disponibles. Le but ici est de faire en sorte que chaque tâche soit attribuée à un processeur possédant son fichier d’entrée tout en ayant le meilleur temps de calcul total. Une autre option étudiée est d’autoriser les tâches nonlocales (attribués à des processeurs ne possédant pas leurs fichiers d’entrée) mais d’en limiter le nombre. Dans cette thèse nous montrons premièrement qu’un algorithme glouton pour ce problème peut être modélisé par un processus de « balls-in-bins » avec choix, impliquant une surcharge (nombre de tâches supplémentaires par rapport à la moyenne) en O(mlogm) où m est le nombre de processeurs. Secondement, dans le cas où les tâches non-locales sont interdites, nous relions le problème à celui de l’orientation de graphes, ce qui permet d’obtenir des algorithmes optimaux et polynomiaux et l’existence d’une assignation presque parfaite avec forte probabilité. Dans le cas où les tâches non locales sont autorisées, nous proposons également des algorithmes polynomiaux et optimaux. Finalement, nous proposons un ensemble de simulations pour montrer l’efficacité de nos méthodes dans le cas de tâches faiblement hétérogènes
The increasing importance of High Performance Computing (HPC) and Big Data applications creates new issues in parallel computing. One of them is communication, the data transferred from a processor to another. Such data movements have an impact on computational time, inducing delays and increase of energy consumption. If replication, of either tasks or files, generates communication, it is also an important tool to improve resiliency and parallelism. In this thesis, we focus on the impact of the replication of input files on the overall amount of communication. For this purpose, we concentrate on two practical problems. The first one is parallel matrix multiplication. In this problem, the goal is to induce as few replications as possible in order to decrease the amount of communication. The second problem is the scheduling of the “Map” phase in the MapReduce framework. In this case, replication is an input of the problem and this time the goal is to use it in the best possible way. In addition to the replication issue, this thesis also considers the comparison between static and dynamic approaches for scheduling. For consistency, static approaches compute schedules before starting the computation while dynamic approaches compute the schedules during the computation itself. In this thesis we design hybrid strategies in order to take advantage of the pros of both. First, we relate communication-avoiding matrix multiplication with a square partitioning problem, where load-balancing is given as an input. In this problem, the goal is to split a square into zones (whose areas depend on the relative speed of resources) while minimizing the sum of their half-perimeters. We improve the existing results in the literature for this problem with two additional approximation algorithms. In addition we also propose an alternative model using a cube partitioning problem. We prove the NP-completeness of the associated decision problem and we design two approximations algorithms. Finally, we implement the algorithms for both problems in order to provide a comparison of the schedules for matrix multiplication. For this purpose, we rely on the StarPU library. Second, in the Map phase of MapReduce scheduling case, the input files are replicated and distributed among the processors. For this problem we propose two metrics. In the first one, we forbid non-local tasks (a task that is processed on a processor that does not own its input files) and under this constraint, we aim at minimizing the makespan. In the second problem, we allow non-local tasks and we aim at minimizing them while minimizing makespan. For the theoretical study, we focus on tasks with homogeneous computation times. First, we relate a greedy algorithm on the makespan metric with a “ball-into-bins” process, proving that this algorithm produces solutions with expected overhead (the difference between the number of tasks on the most loaded processor and the number of tasks in a perfect distribution) equal to O(mlogm) where m denotes the number of processors. Second, we relate this scheduling problem (with forbidden non-local tasks) to a problem of graph orientation and therefore prove, with the results from the literature, that there exists, with high probability, a near-perfect assignment (whose overhead is at most 1). In addition, there are polynomial-time optimal algorithms. For the communication metric case, we provide new algorithms based on a graph model close to matching problems in bipartite graphs. We prove that these algorithms are optimal for both communication and makespan metrics. Finally, we provide simulations based on traces from a MapReduce cluster to test our strategies with realistic settings and prove that the algorithms we propose perform very well in the case of low or medium variance of the computation times of the different tasks of a job

The magneto-optical traps cool and trap atoms in a given region, forming clouds of cold atoms. As the setting of the trap, clouds can be obtained in different geometries such as spherical or ring-shaped. Traps have a wide range of applications, such as building atomic clocks, to obtain the Bose-Einstein condensate and the study of collisions, wherein the ring geometry is interesting to study in low dimensions. The learning of the trap parameters implies in its characterization and thus the appropriate parameters allow to optimize the trap and improve the performance of it s. The objective of our work is to study the behavior of the motion of atoms and the forces that act upon them by varying some parameters of the trap, such as the magnetic field gradient, the detuning between the laser frequency and the atomic transition, the intensity of the laser beams and also the intensity beams profile of the beams. By using the integration method of Runge-Kutta, we present simulations of the trajectory of a trapped atom and the radius of the orbit varying the same parameters of the trap mentioned above. One can find in literature a description of the force exertd on the trapped atoms with Gaussian profile laser beams in the traditional configuration and also with a small misalignment. From the deduction of the force on the trapped atoms with laser beams of Gaussian profile, we present some considerations to find the force acting on the atoms with Gaussian beam profile and simulations in this new configuration. Thus, the possibility of trapping atoms with other intensity beam profiles can be tested.
As armadilhas magneto-ópticas resfriam e aprisionam átomos em uma determinada região, formando nuvens de átomos frios. Conforme a configuração da armadilha, pode-se obter nuvens em diferentes geometrias, como esféricas ou em forma de anel. As armadilhas tem uma grande gama de aplicações, como a construção de relógios atômicos, a obtenção do condensado de Bose-Einstein e o estudo de colisões, no qual a geometria em anel se torna interessante para o estudo em baixas dimensões. Para conhecer os parâmetros da armadilha é necessário fazer sua caracterização. Parâmetros adequados permitem otimizar a armadilha e melhorar a performance da mesma. O objetivo de nosso trabalho é estudar o comportamento do movimento dos átomos e das forças que atuam sobre eles ao variar alguns parâmetros da armadilha, como por exemplo o gradiente de campo magnético, a dessintonia entre a frequência do laser e da transição atômica, a intensidade dos feixes laser e o perfil de intensidade dos feixes. Utilizando o método de integração de Runge- Kutta, apresentaremos simulações da trajetória de um átomo aprisionado e o raio da órbita variando os mesmos parâmetros da armadilha anteriormente citados. Na literatura encontra-se a descrição da força exercida sobre os átomos aprisionados com feixes laser de perfil gaussiano na configuração tradicional e também com um pequeno desalinhamento. A partir da dedução da força sobre os átomos aprisionados com feixes laser de perfil gaussiano, apresentaremos algumas considerações feitas para encontrar a força que atua sobre os átomos com feixes de perfil não gaussiano e simulações realizadas nesta nova consideração. Desta forma, poderá se verificar se existe a possibilidade de aprisionar átomos com feixes de outros perfis de intensidade.

Abstract:

Cette étude est motivée par les besoins réels de calcul dans la physique des réacteurs. Notre objectif est de concevoir les algorithmes parallèles, y compris en proposant efficaces noyaux algébriques linéaires et méthodes numériques parallèles.Dans un environnement many-cœurs en mémoire partagée tel que le système Intel Many Integrated Core (MIC), la parallélisation efficace d'algorithmes est obtenue en termes de parallélisme des tâches à grain fin et parallélisme de données. Pour la programmation des tâches, deux principales stratégies, le partage du travail et vol de travail ont été étudiées. A des fins de généralité et de réutilisation, nous utilisons des interfaces de programmation parallèle standard, comme OpenMP, Cilk/Cilk+ et TBB. Pour vectoriser les tâches, les outils disponibles incluent Cilk+ array notation, pragmas SIMD, et les fonctions intrinsèques. Nous avons évalué ces techniques et proposé un noyau efficace de multiplication matrice-vecteur dense. Pour faire face à une situation plus complexe, nous proposons d'utiliser le modèle hybride MPI/OpenMP pour la mise en œuvre de noyau multiplication matrice-vecteur creux. Nous avons également conçu un modèle de performance pour modéliser les performances sur MICs et ainsi guider l'optimisation. En ce qui concerne la résolution de systèmes linéaires, nous avons proposé un solveur parallèle évolutif issue de méthodes Monte Carlo. Cette méthode présente un degré de parallélisme abondant, qui s’adapte bien à l'architecture multi-coeurs. Pour répondre à certains des goulots d'étranglement fondamentaux de ce solveur, nous proposons un modèle d'exécution basée sur les tâches qui résout complètement ces problèmes
This study is driven by the real computational needs coming from different fields of reactor physics, such as neutronics or thermal hydraulics, where the eigenvalue problem and resolution of linear system are the key challenges that consume substantial computing resources. In this context, our objective is to design and improve the parallel computing techniques, including proposing efficient linear algebraic kernels and parallel numerical methods. In a shared-memory environment such as the Intel Many Integrated Core (MIC) system, the parallelization of an algorithm is achieved in terms of fine-grained task parallelism and data parallelism. For scheduling the tasks, two main policies, the work-sharing and work-stealing was studied. For the purpose of generality and reusability, we use common parallel programming interfaces, such as OpenMP, Cilk/Cilk+, and TBB. For vectorizing the task, the available tools include Cilk+ array notation, SIMD pragmas, and intrinsic functions. We evaluated these techniques and propose an efficient dense matrix-vector multiplication kernel. In order to tackle a more complicated situation, we propose to use hybrid MPI/OpenMP model for implementing sparse matrix-vector multiplication. We also designed a performance model for characterizing performance issues on MIC and guiding the optimization. As for solving the linear system, we derived a scalable parallel solver from the Monte Carlo method. Such method exhibits inherently abundant parallelism, which is a good fit for many-core architecture. To address some of the fundamental bottlenecks of this solver, we propose a task-based execution model that completely fixes the problems

Abstract:

Ce travail avait pour but de déterminer les paramètres des raies d’absorption de la molécule d’ammoniac en vue d’applications atmosphériques. A ce sujet, nous avons mesuré, à température ambiante, les intensités et les coefficients d’élargissement et de déplacement collisionnels des raies des bandes v1, v3, 2v4, et 4v2 dans la région spectrale 3050-3600 cm-1 de NH3 auto-perturbé. Ces mesures ont été effectuées dans un grand nombre de branches de ces bandes avec une très grande précision à l’aide d’un spectromètre infrarouge à transformée de Fourier à haute résolution (0.008 cm-1). Ces paramètres spectroscopiques ont été déterminés à l’aide d’une technique d’ajustement multi-pression utilisant deux profils différents : un profil de Voigt et un profil de Rosenkranz. Le manuscrit comporte cinq parties. La première partie concerne les propriétés spectroscopiques de l’ammoniac. La deuxième partie est dédiée à l’appareillage, avec la description du spectromètre IRTF Bruker IFS125HR. Dans la troisième partie, nous exposons les résultats des intensités et des auto-élargissements de raies isolées, qui sont extrait à partir des spectres enregistré, des bandes v1, v3,2v4 et 4v2 de NH3. La quatrième partie présente les résultats obtenus sur les déplacements de raies et les effets d’interférence entre les composantes des doublets des bandes v1 et v3 de NH3.Pour interpréter les résultats des mesures de largeurs de raies du système collisionnel NH3 auto-perturbé, nous allons présenter dans le chapitre 5 le formalisme adopté pour le calcul de ces largeurs. Une comparaison entre les largeurs calculées et mesurées permet de tester la validité du formalisme utilisé
The aim of this work was to determine the parameters of the absorption lines of the ammonia molecule for atmospheric applications. In this regard, we measured, at room temperature, the intensities, the broadening and the shift coefficients of the lines of the bands v1, v3, 2v4, and 4v2 in the spectral region 3050-3600 cm-1 of self-disturbed NH3. These measurements were carried out in a large number of branches of these bands with very high precision using a high resolution Fourier transform infrared spectrometer (0.008 cm-1).These spectroscopic parameters were determined using a multi-pressure fitting technique using two different profiles: a Voigt profile and a Rosenkranz profile.The manuscript consists of five parts. The first part concerns the spectroscopic properties of ammonia. The second part is dedicated to the apparatus, with the description of the Bruker IFS125HR IRTF spectrometer. In the third part, we expose the results of the line intensities and self-broadenings of isolated lines, which are extracted from the recorded spectra, bands v1, v3, 2v4 and 4v2 of NH3. The fourth part presents the results obtained on line shifts and the interference effects between the components of the doublets of the v1 and v3 bands of NH3.To interpret the results of the line width measurements of the self-disturbed NH3 collisional system, we will present in chapter 5 the formalism adopted for the calculation of these widths. A comparison between the calculated and measured widths makes it possible to test the validity of the formalism used

Abstract:

This study evaluates the efficacy of a self-guided, low-intensity curriculum, Marriage Moments, based on Fowers' (2000) virtues model of marital quality that emphasizes friendship, generosity, justice and loyalty. The Marriage Moments program consists of a guidebook and a video that were designed to strengthen marriages during the transition to parenthood and is used in the context of a home visitation program for first-time parents. Participants in the study included 119 married couples who had recently given birth to their first child. They were assigned to either a treatment, comparison or control group. The treatment group received the Marriage Moments curriculum as well as the Welcome Baby home visitation curriculum, the comparison group only received the Welcome Baby curriculum and the control group received neither program. Data were gathered through a battery of self- and spouse-report measures given at 3-months, 4-months, and 9-months postpartum. Relationship outcome measures included in this study were the Marital Virtues Profile, Revised-Dyadic Adjustment Scale, RELATE Satisfaction subscale, Transition Adjustment Scale, Father Involvement Scale, Household Labor Scale, and Maternal Depression Scale. Despite positive evaluations of the program from participants, analyses revealed a lack of significant, positive effects for members of the treatment group. Further research is needed before reliable conclusions can be drawn about the value of a marital virtues model as a guide for low intensity intervention.

Abstract:

La présente recherche a comme premier objectif d’étudier l’effet de la formation des ressources humaines sur la performance organisationnelle. Le concept de formation des ressources humaines, tel que considérée ici, comporte deux dimensions : l’intensité et l’incidence de la formation mesurées respectivement par la proportion des coûts investis et par la proportion d’employés formés. Les dimensions de la performance organisationnelle retenues sont la productivité et la rentabilité financière. Le second objectif de cette recherche est d’étudier l’effet modérateur du roulement du personnel dans la relation entre la formation et la performance organisationnelle. Les données de la présente recherche sont de nature secondaire. Il s’agit des données colligées par Jalette (1998) auprès de la Fédération des Caisses Desjardins de Montréal et de l’Ouest-du-Québec pour sa thèse de doctorat. Au total, 288 caisses ont été considérées pour la présente étude. Les analyses de régression multiple ont été effectuées dans le but de vérifier l’effet de chaque dimension de la formation sur chaque dimension de la performance organisationnelle. Quatre analyses de régression hiérarchiques nous ont permis de tester l’effet modérateur du roulement du personnel dans la relation entre la formation des ressources humaines et la performance organisationnelle. Les résultats de cette recherche indiquent que les relations examinées sont plus complexes qu’il n’y paraissait à première vue. Tout d’abord, l’effet de la formation sur la performance organisationnelle n’était pas significatif ou allait dans le sens contraire de nos attentes. Par contre, un effet modérateur significatif du roulement du personnel a été identifié dans trois régressions. Ainsi, la relation négative entre l’intensité de la formation et la rentabilité financière est moins prononcée dans un milieu où le roulement est élevé que dans un milieu où il est faible. Aussi, dans un milieu où le roulement est élevé, la relation entre l’incidence de la formation et la productivité est positive tandis qu’elle est négative dans un contexte où le roulement est bas. Ces deux effets modérateurs vont cependant dans le sens contraire à celui attendu. Cependant, l’hypothèse huit a été vérifiée : ainsi, dans un contexte où le roulement du personnel est élevé, la relation entre l’incidence de la formation et la rentabilité financière est négative tandis qu’elle est positive dans un contexte où le roulement est bas.
The first objective of the present research is to study the association between human resources training and organizational performance. The concept of human resources training, as considered in this study, includes two dimensions: intensity and incidence of training, respectively measured by the proportion of wage bills spent on training and the proportion of employees trained. The dimensions of organizational performance considered are the productivity and the financial profit. The second objective of this research is to study the moderating effect of the turnover in the relationship between training and organizational performance. The data in the present study were collected by Jalette (1998) during his doctoral studies. This data contain information collected from the Federation of Desjardins establishments from Montreal and West of Quebec. A total of 288 establishments were considered for this study. Regression analyses were conducted to verify if each of our dimensions of training has an effect on each dimension of organizational performance. We also tested, with four regression analyses, the presence of a moderating effect of turnover in the relationship between human resources training and organizational performance. The results of the present study indicate that the examined relations are more complex than they initially seemed to be. First of all, the effect of training on organizational performance was not significant or was contrary to our expectations. On the contrary, a significant moderating effect of turnover was identified in three regressions. In fact, the negative relation between intensity of training and financial profit is less pronounced in an environment where turnover is high compared to an environment where turnover is low. Also, in an environment where turnover is high, the relation between incidence of training and productivity is positive but it is negative in an environment where turnover is low. These two moderating effects are in the opposite direction than what we expected. However, our eighth hypothesis was verified : in an environment where turnover is high, the relation between incidence of training and financial profit is negative while it is positive in a context where turnover is low.

This research focused on the interactive relationship of the variance such as turnover intention, satisfaction of profit sharing, job satisfaction, job involvement and stress of work. The objects of the research are random sampling by the direct labels (operators work directly with production line) of tsmc, total 242 effective samples. The motive of this research initiated by means of high profit sharing in high-tech industry to attract talented persons in recent years. The rapid changes in production by highly growth also caused the serious stress to operators and hence high turnover ratio and then increase in operation cost. This research uses T-test, single variance analysis, Pearson analysis and step-by-step regression to study the relations of variance. The main finding of this research can be concluded to: 1.The satisfaction of profit sharing had high relation with job satisfaction, job involvement, job stress and turnover intention. Higher satisfaction of profit sharing results in higher job satisfaction, higher job involvement and lower work stress, lower turnover intention. 2.Job satisfaction affects job involvement, job stress and negative relate to turnover intention, the higher job satisfaction, the lower turnover intention. 3.The chance and channel of promotion is one of the important factor to job satisfaction. 4.Job involvement is negative to turnover intention, and also a prediction of turnover and job stress. 5.Job stress is positive to turnover intention, to reduce the work stress can also diminish turnover intention effectively I hope the conclusions and suggestions coming out from the research can apply to the domestic companies implementing profit sharing to design organization/system to improve employee’s satisfaction, job involvement and diminish job stress, turnover intention effectively, hence to lower down the turnover intention, improve the production efficiency and reduce the operation cost.

Methods: There were used biomedical measurements as a body measuring, bioelectrical impedance, laboratory spiroergometric measuring by maximal stress testing. Field spiroergometric measuring was provide during simulated match in pool hall. To find the role of physical fitness in performance billiard were used half structured interview with open questions and online survey. Results: The findings show that tested billiard players achieve levels of physical fitness from average to very good values. But some of them are classified as overweight and obese. Long-time playing billiard does not have any important influence on asymetric composition of muscle mass of upper limbs. During playing billiard an oxygen consumption didn't get over 30% of VO2max and values of heart rate were between 39 to 59% HRmax. During playing billiard an energy expenditure grows from 222 to 330% of BM. Billiard energetic demands of tested players are moving between 14,6 kJ to 29,3 kJ. Another result of thesis is a statement about the role of...
