Yes / This study presents an original asymmetric stepped-impedance resonator filter combined with meander coupled-line structures and enabling the realisation of finite transmission zeros (TZs) and the implementation of multi-band bandpass filters. The meander coupled sections (MCSs) tune the TZs and resonant frequencies: with higher-order spurious frequencies cancelled by the TZs, a single wideband with wide stopband from 1.18 to 1.84 GHz is possible. Furthermore, by positioning the finite TZs between the high-order spurious frequencies and adjusting the coupling strength between resonators, a quint-wideband filter can be realised, with centre frequencies of 1.19, 4.29, 5.43, 6.97, 9.9 GHz and fractional bandwidths of 31.9, 15.4, 15.8, 4.3, 39.2%, respectively. More importantly, two filters with single/quad-wideband performance can be realised by tuning the parameters of the MCS, and therefore they can be designed separately by using only one original structure. The triple-wideband filter is realised with the help of the asymmetric parallel uncoupled microstrip section. These filter structures enjoy the advantage of single/multi-band versatility, structure reusability and simplicity. The good in-band and out-of-band performance, low loss and simple structure of the proposed single/tri/quint-wideband filters make them very promising for applications in future multi-standard wireless communication. / European Union's Horizon 2020 research and innovation programme under Grant agreement H2020-MSCA-ITN-2016 SECRET-722424.

In recent years, as the availability of remote sensing imagery of varying resolution has increased, merging images of differing spatial resolution has become a significant operation in the field of digital remote sensing. This practice, known as data fusion, is designed to enhance the spatial resolution of multispectral images by merging a relatively coarse-resolution image with a higher resolution panchromatic image of the same geographic area. This study examines properties of fused images and their ability to preserve the spectral integrity of the original image. It analyzes five current data fusion techniques for three complex scenes to assess their performance. The five data fusion models used include one spatial domain model (High-Pass Filter), two algebraic models (Multiplicative and Brovey Transform), and two spectral domain models (Principal Components Transform and Intensity-Hue-Saturation). SPOT data were chosen for both the panchromatic and multispectral data sets. These data sets were chosen for the high spatial resolution of the panchromatic (10 meters) data, the relatively high spectral resolution of the multispectral data, and the low spatial resolution ratio of two to one (2:1). After the application of the data fusion techniques, each merged image was analyzed statistically, graphically, and for increased photointerpretive potential as compared with the original multispectral images. While all of the data fusion models distorted the original multispectral imagery to an extent, both the Intensity-Hue-Saturation Model and the High-Pass Filter model maintained the original qualities of the multispectral imagery to an acceptable level. The High-Pass Filter model, designed to highlight the high frequency spatial information, provided the most noticeable increase in spatial resolution. / Master of Science

This thesis explores the optimization of process parameters for producing single-track thin walls using Laser Powder Bed Fusion (LPBF) additive manufacturing. Using two different coupon designs, the study assesses the feasibility of creating the thinnest possible leak-tight structures within LPBF and evaluating their mechanical properties, including burst pressure and modulus of elasticity under pressure loads. A series of experimental iterations were conducted, varying laser power and laser speed to identify optimal conditions. The findings indicate that a narrow range of process parameters can produce consistently leak-tight thin walls. The results contribute to understanding how to achieve high quality, reliable thin wall structures in the LPBF process, with implications for industrial applications requiring thin, precise, leak tight, and durable walls.

L’altération du métabolisme postprandial des lipides et l’inflammation chronique associée apparaissent comme des éléments majeurs de la physiopathologie de l’obésité. L’implication de l’absorption intestinale d’endotoxines bactériennes du microbiote au cours de la digestion des lipides a été mise en évidence. Cependant la modulation de ces phénomènes par différentes quantités de lipides différemment structurés reste mal caractérisée, notamment chez les obèses. Nous avons mis en place un protocole clinique, en cross-over randomisé, visant à étudier chez des sujets normo-pondérés et obèses les conséquences de la digestion de matière grasse consommée, soit sous forme tartinée en différentes quantités (10 g ou 40 g), soit sous forme finement émulsionnée (40 g) sur le métabolisme postprandial des lipides et des endotoxines. Nous avons ainsi mis en évidence que l’augmentation plasmatique des chylomicrons, suite à une augmentation de la quantité de matière grasse ingérée, était plus précoce et plus importante chez les normo-pondérés que chez les sujets obèses, avec la sécrétion de plus gros chylomicrons suite à 40 g. Lorsque 40 g de matière grasse est émulsionnée, nous montrons qu’elle aboutit à un pic de triglycérides des chylomicrons plus précoce et plus élevé, reflétant une absorption facilitée des lipides, et de manière plus marquée chez l’obèse. Nous montrons aussi que cet état émulsionné aboutit à une β-oxydation plus élevée des lipides exogènes sur la journée, sans différence de perte fécale. Une endotoxémie postprandiale est également observée suite aux différents repas. L’accumulation postprandiale d’endotoxines, notamment présentes dans les chylomicrons, augmente avec la quantité de matière grasse tartinée en corrélation avec l’aire sous courbe des chylomicrons chez les obèses. En complément, l’absorption lipidique in vitro par des cellules Caco-2 était plus importante suite à l’incubation de milieux de lipolyse d’émulsions stabilisées par du caséinate que de la lécithine. Enfin, un test de digestion a été réalisé avant et après une chirurgie de by-pass gastrique pour identifier si une diminution drastique de l’absorption lipidique modifiait l’endotoxémie. Suite à l’opération, les patients sont davantage exposés aux endotoxines après la prise d’une émulsion au petit-déjeuner. En revanche, la LBP, protéine de transport des endotoxines proinflammatoire, diminue significativement à jeun et en postprandial suite à l’opération. L’ensemble de ces travaux démontrent qu’en plus des effets de la quantité de lipides ingérée sur la lipémie et l’absorption d’endotoxines associée, la structure de la matière grasse joue un rôle important dans la modulation du devenir métabolique des acides gras. La structuration des lipides alimentaires pourrait donc être spécifiquement adaptée afin d’optimiser le métabolisme lipidique postprandial, notamment chez des personnes obèses. / The alteration of postprandial lipid metabolism and associated chronic inflammation emerge as major elements in the obesity pathophysiology. The involvement of the intestinal absorption of endotoxin from microbiota during lipid digestion was recently highlighted. However, the modulation of these phenomena by different amounts of differently structured lipids remains poorly characterized, especially in obese people. We developed a cross-over randomized clinical study to explore in normal weight and obese subjects the consequences of fat digestion, consumed either spread on bread in different amounts (10 g or 40 g) or finely emulsified (40 g), on postprandial metabolism of lipids and endotoxins. We have demonstrated that the increase in plasma chylomicrons, after increase in the amount of fat ingested, was earlier and greater in normal-weight than in obese subjects, with the secretion of larger chylomicrons after consumption of 40 g of spread fat. When 40 g of fat is emulsified, we show that it leads to an earlier and higher peak of chylomicron triglycerides, reflecting facilitated absorption of fat, and more significantly in obese subjects. We also show that emulsified fat results in higher β-oxidation of exogenous lipids over the day, with no difference in fecal excretion. Postprandial endotoxemia was also observed in response to different meals. The postprandial accumulation of endotoxins, present in chylomicrons, increases with the amount of spread fat ingested and it is correlated with the area under the curve of chylomicrons in obese subjects. In addition, the in vitro lipid absorption by Caco-2 cells was greater following incubation with lipolysis media of emulsions stabilized by caseinate than lecithin. Finally, a digestion test was conducted before and after gastric bypass surgery to identify whether a drastic reduction in lipid absorption altered metabolic endotoxemia. After surgery, patients are more exposed to endotoxins in the morning after emulsion consumption at breakfast. However, LBP, a proinflammatory protein transporting endotoxins, significantly decreases after surgery. Altogether, these studies demonstrate that in addition to the metabolic effects of dietary fat intake on lipemia and associated endotoxemia, the fat structure also plays an important role in the modulation of further fatty acid handling. Structuring of dietary lipids could thus be specifically adapted to optimize postprandial lipid metabolism, especially in obese people.

A lo largo de estos años de existencia del grupo de investigación se han ido desarrollando un volumen de casos donde se comenzó a evidenciar un hecho: niños y adolescentes llegaban derivados a la consulta por problemas de aprendizaje, pero éstos no siempre respondían a que tuvieran unos procesos cognitivos por debajo de la media. Por tanto, no se explicaba su bajo rendimiento escolar. Ante estos casos nos planteamos como intervenir en esta realidad educativa. Indagando descubrimos que la mayoría de estos también tenían problemas a nivel emocional. La pregunta inmediata que nos hicimos fue: podemos llegar a pensar que quizás los procesos emocionales influyen directamente en los procesos cognitivos? El estado emocional influye directamente en los procesos cognitivos?Los procesos cognitivos y emocionales son un todo inseparable? Estas dudas son las que me llevaron a proponer esta investigación: ver la relación que puede haber entre los procesos cognitivos y los procesos emocionales, evidentemente, siempre centrados desde el Modelo Humanista- Estratégico (modelo del grupo de investigación): a nivel cognitivo, Teoría PASS de la Inteligencia; a nivel emocional, la Teoría del Procesamiento Cerebral de las Emociones.Se plantea la tesis estructurada en dos partes: Parte teórica: explicación de la Unidad de Neuropsicopedagogía del Hospital Dr. Trueta de Girona (UNPP) donde se realiza la investigación, revisión teórica de procesamiento cognitivo, procesamiento emocional y su relación mutua. 2.- Parte práctica: objetivos, metodología, resultados, análisis- discusión, implicaciones educativas y conclusiones. El objetivo general es establecer una relación entre el procesamiento cognitivo y emocional a partir de la relación de los procesos cognitivos PASS con problemas emocionales en niños y niñas de entre 5 y 16 años. Para conseguirlo se pretende: 1. Establecer la relación entre procesamiento PASS y los efectos de la intervención emocional según el Modelo Humanista - Estratégico; 2. Analizar la relación entre procesamientos cognitivos PASS y los efectos de la intervención cognitiva según la Teoría PASS de la Inteligencia; 3.Comprobar si los procesos PASS varían en el transcurso de más de seis meses sin ningún tipo de intervención ni emocional ni cognitiva, 4. Comprobar si los resultados obtenidos en los tres primeros objetivos se diferencian entre ellos para determinar el componente emocional en los procesos cognitivos PASS, y 5. Establecer orientaciones prácticas para la intervención psicopedagògica considerando la relación de procesos emocionales, cognitivos y aprendizaje.Para poder llevar a cabo esta investigación, la metodologia utilizada es: una metodologia cuantitativa ya que se realiza una investigación experimental enmarcada como un diseño mixto 3x2 con el primer factor ínter sujeto y el segundo factor intra sujeto. Y por otra parte, una metodologia cualitativa. ya que en la primera muestra se realiza una intervención psicopedagógica en base emocional a cuarenta casos de la UNPP, y en la segunda muestra se realiza una intervención psicopedagògica en base cognitiva a treinta casos de la UNPP.Los resultados comparativos nos corraboran afirmativamente la hipotesis y objetivos, facilitando realizar un analisis-discusión muy interesante aportando las implicaciones educativas que acarrean, y por consiguiente llegando a las conclusiones. De entre éstas destacamos principalmente:1. La intervención emocional es eficaz para mejorar el rendimiento cognitivo, si tenemos en cuenta que a pesar que no se ha realizado intervención cognitiva se ha producido una mejora en el rendimiento escolar.2. La intervención cognitiva PASS es eficaz para la mejora del rendimiento cognitivo y la desaparación de las dificultades de aprendizaje cuando el origen de estas es cognitivo. 3. En las diferencias en planificación se observa que se ha producido un incremento mayor y sustancial en el grupo que ha recibido intervención emocional. 4. Y por consiguiente, podemos decir que la emoción se interrelaciona con la cognición a través del procesamiento cognitivo de planificación. / Since the existence of the group of investigation, many children and teenagers have been developing apprenticeship problems. This event was not a consequence of cognitive processes in every case, for this reason, the low scholarship efficiency was hard to explain. Confronting this situation, we discovered that the most of them had emotional problems also. The every next question that appeared was: Does the emotional situation affect cognitive problems directly? Do cognitive processes and emotional situations go together? This questions are the things that motivated this investigation, looking for the relationship that could appear between these situations, utilizing a theory model: Model Humanista- Estratégico (Pérez, Timoneda 2001). The thesis is structured in two separated parts: the theoric part, which explains the Unit of neuropsicopedagogy (UNPP) from the Hospital Dr. Trueta de Girona (Spain), where the investigation was developed. The practice part analyzes the objectives, methodology, outcomes, educative implications and conclusions.The principal aim to determine the real relationship between people's cognitive process (based on the PASS Theory) and the emotional process (based on Humanist-Strategic Model) in children with emotional problems and learning difficulties (age: 5 to 16). That's why we had to:1.Establish the relationship between PASS processes and effects of emotional intervention done (based on Humanist - Strategic Model)2.Analyse the relationship between PASS processes and effects of cognitive intervention done (based on PREP - PASS Theory)3. Verify PASS processes change without any type of intervention done during six months. 4.Prove if the results in the three first objectives discriminate among them in order to determine the emotional component assessing the PASS cognitive processes. 5. Establish practice orientations for pedagogic intervention considering the relationship between emotional process, cognitive process, and learning. To be able to develop this investigation the method to be utilize is: a quantitative methodology which performs an experimental investigation, mix design 3x2 with a first factor inter subject and a second factor intra subject. And other hand, a qualitative methodology: The emotional intervention carried out in forty cases in UNPP and the cognitive intervention carried out in thirty cases in UNPP.The comparative outcomes do verify the hypothesis and the objectives. In consequence an analyses - discussion is developed, that the contributes to the education. The most important conclusions to emphasize are :1. The emotional intervention is efficient to improve cognitive efficiency when the origin of learning difficulties are emotional.2. The cognitive intervention based on PASS is efficient to improve cognitive ability. Moreover, thanks to the cognitive intervention the learning difficulties disappear when their origin are cognitive.3. In the planning differences you can see that a higher increase has been produced in the group that has received emotional intervention. In the control group no change has been produced. 4. And finally, we want to point out the most important conclusion: the emotion is related to the cognition through the planning process. That's why, it's impossible to separate cognition from emotion. Both of them have a strong relation.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This work shows and compares three different flux estimator algorithms developed for use in high-performance sensorless ac motor drives. The first algorithm uses a low pass filter with a very low cut off frequency to integrate the back electromotive force (emf). The second one uses a high pass filter to remove the offset present in the signal before it s integration. The third algorithm uses current and voltage model to estimate the flux of induction motor. These algorithms can be used to accurately measure the motor flux including magnitude and phase angle over a wide speed range. The performance of the algorithms is investigated, compared, and verified using simulation and experimental tests. / Este trabalho tem como objetivo apresentar uma comparação entre três algoritmos estimadores de fluxo estatórico diferentes. Estes algoritmos foram desenvolvidos para serem usados no projeto de acionamentos de alto desempenho, sem sensor de velocidade, para motores de indução. O primeiro algoritmo adotado utiliza um filtro passa baixa com uma freqüência de corte baixa para resolver a integração. O segundo algoritmo usa um filtro passa alta para retirar o offset do sinal de entrada do integrador puro. O terceiro algoritmo é um algoritmo híbrido que utiliza os modelos de tensão e corrente em paralelo para estimar o fluxo. Os algoritmos estimam fluxo estatórico em uma ampla faixa de freqüência de funcionamento do motor de indução e foram implementados na forma de simulação e experimentalmente para comparar o funcionamento dos mesmos em diferentes velocidades de operação do motor. / Mestre em Ciências

This study aimed to examine whether there are differences in the transmission of exchange rate changes on export prices (coefficient of pass-through) the soy complex (beans, meal and oil) between the United States, Brazil and Argentina. Moreover, the specific objectives were to a) describe the characteristics of American markets, Brazil and Argentina in terms of the exports of soybean complex, b) estimate the degree of pass-through of American markets, Brazil and Argentina, and c) review differences in the degree of pass-through between the three countries. The analysis period was from January 2003 to January 2012. As a method, we used time series econometrics to estimate the proposed model, the following procedures: checking the stationarity of the series; selection of lag for the VAR auxiliary; Johansen cointegration test, estimating the cointegration vector, and diagnostic tests for model. The results showed that the United States is the most competitive in the passthrough to the export price of grain and soybean meal. As for soybean oil, the most competitive country in the passthrough is Argentina. / Este trabalho teve como objetivo principal analisar se há diferença na transmissão da variação cambial nos preços de exportação (coeficiente de pass-through) do complexo da soja (grão, farelo e óleo) entre Estados Unidos, Brasil e Argentina. Além disso, os objetivos específicos foram de a) Descrever as características dos mercados americano, brasileiro e argentino no que tange as exportações do complexo da soja; b) Estimar o grau de pass-through dos mercados americano, brasileiro e argentino; e c) Analisar as diferenças entre o grau de passthrough entre os três países. O período de análise foi de janeiro de 2003 a janeiro de 2012. Como método, utilizou-se econometria de séries temporais para estimação do modelo proposto, seguindo os procedimentos: verificação da estacionariedade das séries; seleção de defasagem para o VAR auxiliar; teste de cointegração de Johansen; estimação do vetor de cointegração; e testes diagnósticos para o modelo. Como resultados, observou-se que Estados Unidos é o mais competitivo no repasse cambial para o preço de exportação do grão e do farelo de soja. Já para o óleo de soja, o país mais competitivo no repasse cambial é a Argentina.

Le by-pass gastrique Roux-en-Y (BPG) est une chirurgie de l'obésité qui induit des améliorations spectaculaires de l'homéostasie glucidique indépendamment de la perte de poids. Un mécanisme proposé pour expliquer ces améliorations est une augmentation de la production intestinale de glucose (PIG) qui induit des effets bénéfiques sur l'organisme (satiété, amélioration de la sensibilité hépatique à l'insuline). Cette augmentation de la PIG, retrouvée chez la souris ayant subi un BPG simplifié, est également responsable des effets bénéfiques des régimes enrichis en protéines via l'inhibition des récepteurs mu-opioïdes (RMO) par les peptides. Nous avons donc testé l'hypothèse selon laquelle les effets bénéfiques du BPG dépendraient d'une inhibition des RMO par les protéines alimentaires et nous avons également testé le rôle causal de la PIG dans ces améliorations métaboliques. Pour cela, nous avons réalisé un by-pass duodéno-jéjunal (BDJ), ie un BPG sans restriction gastrique, chez des souris sauvages (WT), des souris invalidées pour le gène du RMO (MOR-/-) et des souris dépourvues de PIG (I-G6pc-/-). Chez les souris obèses, Le BDJ induit une forte perte de poids (–30%), en partie expliquée par une malabsorption lipidique, ainsi qu'une amélioration des paramètres glucidiques dépendante de cette perte de poids. Au contraire, chez la souris de poids normal, le BDJ n'induit ni perte de poids ni malabsorption mais améliore la tolérance au glucose. Les effets sont les mêmes chez les souris WT, MOR-/- et I-G6pc-/- ce qui montre que les récepteurs mu-opioïdes et la PIG ne semblent pas avoir de rôle causal dans les améliorations du métabolisme énergétique et glucidique après BDJ / Roux-en-Y gastric bypass procedure (GBP) is an obesity surgery that induces dramatic glucose homeostasis improvements independently of weight loss. A proposed mechanism to explain these glucose homeostasis improvements is an increase in intestinal glucose production (IGP) that induces beneficial effects on metabolism (satiety, improved liver insulin sensitivity). This increase in IGP is found in mice that have undergone a simplified GBP and is also responsible for the beneficial effects of protein-enriched diets through the inhibition of mu-opioid receptors (MOR) by alimentary peptides. We therefore hypothesized that the beneficial effects of GBP could depend on MOR inhibition by dietary proteins and we also tested the causal role of IGP in these metabolic improvements. For this purpose, we performed a duodenal-jejunal bypass surgery (DJB), ie GBP without gastric restriction, in wild-type mice (WT), in mice lacking MOR gene (MOR-/-) and in mice lacking IGP (IG6pc-/-). In obese mice, DJB induced a rapid and substantial weight loss (-30%), partly explained by fat malabsorption, and weight loss-dependent improvements of glucose homeostasis. In contrast, in the non-obese mice, DJB did not induce weight loss nor malabsorption but improved glucose tolerance. Effects were similar in WT, MOR-/- and I-G6pc-/- mice showing that mu-opioid receptors and IGP did not appear to have a causal role in glucose and energy metabolism improvements after DJB

Sports analytics is an area that is growing at a rapid rate. It can be described as the use of data and analytics to gain an advantage in sports. It can include scouting, recovery, tactics and so on. This thesis uses data about association football passes to analyse players passing attributes. The dataset that has been used is acquired from the company Football Analytics Sweden AB and is produced by a subcontractor. The dataset includes event data for all games played in the Swedish division 1 during the 2020 season. In total there are 48 different types of events, but only the category passes accurate are analysed. Accurate passes are represented by x and y coordinates for the start and end point of the pass. The thesis's intention is the study how passes can be categorized in order to differentiate different players passing attributes, and how to identify types of players in regard to passing from that categorization. The categorization has been made possible by dividing the football pitch into different zones. The zones have been chosen on sports science and football grounds. Every pass is assigned a category based on which zone the pass starts in and what zone the pass ends up in. The proportion of passes a player hits for every category is then calculated and is used to perform factor analysis. The factor analysis identifies 13 underlying factors that can describe players different passing attributes. These factors have been interpreted and given names. The factors describe both general attributes as well as more specific attributes. Factor scores are then used to compare and identify which or what type of passing player a particular player is. / Sports analytics är ett begrepp som används mer och mer. I allmänhet kan det beskrivas som användningen av data och dataanalys för att få en fördel inom sport. Det kan vara allt från scouting (rekrytering av spelare), återhämtning och taktik. Den här studien använder information om fotbollspassningar för att undersöka fotbollsspelares passningsegenskaper. Datamaterialet som använts är erhållet från företaget Football Analytics Sweden AB och är framtaget av en underleverantör. Datamaterialet innehåller händelsedata för alla matcher som spelades i division 1 under säsongen 2020. Totalt finns det 48 olika typer av händelser, men endast händelsen lyckade passningar tas i beaktande. Lyckade passningar representeras av x och y koordinater för start- och slutpunkten för passningen. Studiens syfte är att undersöka hur passningar kan kategoriseras för att göra det möjligt att differentiera olika spelares passningsförmågor och hur man kan identifiera typ av passningsspelare utifrån kategoriseringen. Kategorisering av passningar utfördes med hjälp av en zonuppdelning av fotbollsplanen. Zonuppdelning är grundad på sportvetenskapliga och fotbollsmässiga grunder.  Varje passning tilldelas en kategori beroende på vilken zon passningen startar och slutar i. Andelen av passningar en spelare slår inom varje kategori beräknas, för att sedan användas i en faktoranalys. Faktoranalysen identifierar bakomliggande faktorer som påverkar en spelares andelar av passningar inom varje kategori. Totalt identifierades 13 bakomliggande faktorer och dessa kan beskriva en spelares passningsegenskaper. Dessa faktorer har verklighetstolkas och namngetts. Faktorerna beskriver både allmänna egenskaper och mer specifika egenskaper.  Faktorpoäng som beräknats från dem bakomliggande faktorerna används sedan för att jämföra och identifiera vilka eller vilken typ av passningsspelare en spelare är.
