Today, designers work in tandem with computerized tools to create stylized graphic designs, diagrams, and icons. In this work, we explore the applications of generative modeling to the design of vectorized drawings, with a focus on font glyphs. We establish a data-driven approach for creating preliminary graphics upon which designers can iterate. To accomplish this, we present an end-to-end pipeline for a supervised training system on Scalable Vector Graphics (SVGs) that learns to reconstruct training data and produce similar but novel examples. We demonstrate its results on selected characters using a Google Fonts dataset of 2552 font faces. Our approach uses a variational autoencoder to learn sequences of SVG drawing commands and is capable of both recreating ground truth inputs and generating unseen, editable SVG outputs. To investigate improvements to model performance, we perform two experiments: one on the effects of various SVG feature encodings on generated outputs, and one on a modified architecture that explicitly encodes style and class separately for multi-class generation.

The content of this work is the design and implementation of HW supported by SW for viewing subtitles into the movie, which translates from the projection equipment on 16 mm film, synchronizing subtitles with the movie, at the same time the work also addresses the issues of principle changes the distance of the canvas. Subtitles are loaded by using the SD card slot control by using the control, which is used to display graphics monochrome buttons that are also used for setting the device and its modifications.

Stylized Stroke Fonts (SSF) are stroke fonts which allow variable stroke widths and arbitrary stroke ends. In this thesis project we implement SSF by extending concepts of the traditional vector graphics paradigm, giving what we call Vector Graphics Stylized Stroke Fonts (VGSSF). A stroking algorithm for the new stroke model is developed and implemented in the Opera web browser's internal vector graphics drawing toolkit. Both the HTML 5 Canvas JavaScript interface and SVG fonts are extended to support the new stroke model. An editor and renderer for the SVG font format is implemented inside the browser using the extended Canvas interface. Sample glyphs from Latin and Chinese typefaces are converted to the SVG font format to assess the suitability of the stroke representation. The results are excellent for Chinese Ming typeface glyphs, while there are some minor problems with Latin typeface glyphs. Approximations suggest that VGSSF gives a size reduction of the font definition file by at least 50%, with a potential reduction of around 85% for Chinese typefaces. The processing requirements increase by approximately 20-30% due to extra steps required to render each glyph.

Depuis maintenant près d’un siècle, des robots sous-marins ont été développés afin de réaliser des tâches spécifiques aux besoins des grands acteurs historiques du domaine (militaires, pétroliers, câbliers ou explorateurs benthiques) sans vraiment se soucier de la polyvalence et de la modularité de la plateforme. L’objectif de cette thèse est d’avoir une réflexion sur une solution technologique et scientifique avec comme domaine applicatif l’environnement faible fond ou confiné. Il s’agit en d’autres termes de concevoir un robot sous-marin que l’on peut faire évoluer aisément tant sur le plan mécanique, électronique qu’informatique. Cet objectif impose de proprement conceptualiser cette « polyvalence » en s’attachant à apporter de l’abstraction dans l’architecture de contrôle que se soit au niveau de l’automatique avec l’expression de la polyvalence liée à l’étage d’actionnement ou de l’informatique avec une architecture basée services, pouvant être composés, afin de répondre à la diversité des besoins applicatifs. L’ensemble de ces travaux a pour point de départ le robot Jack mis au point par l’entreprise Ciscrea, partenaire industriel, qui apporte un aspect économique à la nécessité de développer une solution polyvalente pouvant être décliné en une gamme de produits. Ce manuscrit traite de la conception, la réalisation et l’expérimentation de ce vecteur que ce soit en piscine où en environnement réel
Since almost a century, underwater robots have been developed in order to respond to the specific needs of historical actors of the domain (military, hydrocarbons exploitation, underwater cabling or benthic exploration), without addressing specifically the question of versatility or modularity of the underwater platform. This thesis aims to address these questions on a technological solution dedicated to shallow water or confined environment. In other words, the objective is to realise an underwater system, able to evolve on the mechanical, electronical or software aspects. This requires to properly conceptualise this « versatility » with an abstraction of the control architecture, on the actuation aspect, with the expression of the versatility linked to the actuation systems, or on the software architecture level, with a Service-Oriented-Architecture (SOA) approach, in order to tackle the diversity of the application requirements. This study is based on the Jack system, developed by the Ciscrea Company, which is the industrial partner of this project, and brings the economical aspect as a central requirement. This underlines another view of the versatility question, the development of a range of product for the Ciscrea Company.This thesis proposes the conception, realisation and experimentation of such a versatile underwater system, with test-tank and field validation

Resumo: A presente tese refere-se a um modelo de controle de corrente para conversores em matriz trifásico para trifásico e inversores fonte de tensão trifásica sem capacitor no elo de corrente continua com o objetivo minimizar e compensar as distorções presentes nas tensões de saída dos conversores de modo a obter correntes elétricas senoidais na carga. Nesses conversores, por não possuírem elementos armazenadores de energia de grandes valores, os desequilíbrios e/ou distorções presentes nas tensões de entrada irão se refletir nas tensões de saída. O modelo de controle de corrente proposto consiste em manter constante o módulo do vetor espacial das correntes de saída do conversor em matriz por meio de um regulador PI que altera dinamicamente a razão cíclica de acionamento das chaves de potência compensando os desequilíbrios e distorções das tensões trifásicas de entrada. O desempenho do controle proposto é validado por meio de simulações executadas no Matlab e em resultados experimentais obtidos no protótipo de um inversor fonte de tensão sem capacitor no elo de corrente continua alimentando uma carga RL trifásica
Abstract: This thesis concern a current control method for three-phase matrix converter and three-phase voltage source inverter without a dc link capacitor in order to mitigate and compensate the distortions present in the output voltages so that the output currents are sinosoidal. In these converters, because of lack of large storage elements, imbalances and/or distortions present in the input voltage will be immediately reflected to the converter output voltages. The proposed current control model forces the magnitude of the output space vector current to be constant through a PI controller that dynamically alters the duty cycle of the power converter switching for compensating the imbalances and distortions from input voltages. The performance of this current control is validated by simulations implemented in Matlab and experimental results on the prototype of a voltage source inverter without a DC link capacitor feeding a three-phase RL load

The Sandflies are insects diptera nematocera belonging to the Psychodidae family, very important for public health, because some species are vectors of etiological agents of leishmaniasis, endemic parasitic disease in the state of Maranhão and in Brazil. These vectors are frequently found in natural ecotopes, domestic animal shelters and human habitations. This research aimed to study the occurrence of sandflies in the urban and rural peridomiciliary environment of municipality of Caxias, Maranhão, in notification area of cases of cutaneous and visceral leishmaniasis, as well as the rate of natural infection by Leishmania and analysis of blood food source. This is a cross-sectional, exploratory, descriptive and field study, with a quantitative approach, performed from March 2013 to February 2015. The specimens were collected with CDC (Center for Disease Control) light traps type in 20 homes, 10 in urban area and 10 in rural area. Were collected 15,895 specimens belonging to 17 species, one of genus Brumptomyia and 16 of Lutzomyia. The most abundant species were Lu. longipalpis (90.26%) and Lu. whitmani (7.65%). In the urban area the abundance of sandflies was higher in rainy season, and in the rural area in the dry season. Lu. longipalpis and Lu. whitmani occurred in two seasons, most frequently in rainy and dry season, respectively. From a total of 3, 520 female, 982 samples were used for DNA and PCR-RFLP extraction for detecting the presence of Leishmania. The vector Lu. longipalpis was found infected by Le. infantum (3.0%); Le. shawi (0.3%); Le. mexicana (0.2%); Le. braziliensis (0.6%) and Le. guyanensis (0.6%) and with mixed infection Le. infantum/Le. braziliensis (0.6%). The specie Lu. whitmani was infected by Le. infantum/Le. braziliensis (4.0%) and Le. braziliensis (4.3%). Other species found infected include: Lu. trinidadensis with Le. infantum/Le. braziliensis and Lu. evandroi and Lu. termitophila with Le. braziliensis and Le. guyanensis respectively. Based on these results it is suggested adopting control measures by the public health authorities to contain a future epidemic of AVL in this area, which is also endemic to ACL. For detection of food source were captured 778 engorged females, 573 were positive for eight different types of domestic and wild animals: dog, man, chicken, ox, pig, horse, rodent and opossum; obtaining mixed reactions in eight different associations: dog/rodent, man/chicken, chicken/rodent, dog/chicken, horse/rodent, rodent/pig and man/opossum. The presence of sandflies species infected with different species of leishmanias and fed with blood of domestic animals and human justifies the occurrence of endemic form of visceral and cutaneous leishmaniasis in the municipality of Caxias. Based on these results it is suggested adoption of control measures by the public health authorities to contain a future epidemic of these diseases.
Os flebotomíneos são dípteros nematóceros, pertencentes à família Psychodidae, muito importantes para a saúde pública, pois algumas espécies são vetores dos agentes etiológicos das leishmanioses, doenças parasitárias endêmicas em todo o território brasileiro. Esses vetores são encontrados com frequência em ecótopos naturais, abrigos de animais domésticos e habitações humanas. A presente pesquisa teve como objetivo estudar a ocorrência de flebotomíneos no ambiente peridomiciliar urbano e rural do município de Caxias, Maranhão, em área de notificação de casos de leishmaniose tegumentar e visceral, bem como, a taxa de infecção natural por Leishmania e análise da fonte alimentar sanguínea. Trata-se de um estudo transversal, exploratório, descritivo e de campo, tendo uma abordagem quantitativa, realizado no período de março de 2013 a fevereiro de 2015. Os espécimes foram coletados com armadilhas luminosas do tipo CDC (Center for Disease Control) em 20 residências, 10 na zona urbana e 10 na zona rural. Foram coletados 15.892 espécimes pertencente a 17 espécies, sendo uma do gênero Brumptomyia e 16 do gênero Lutzomyia. As espécies mais abundantes foram Lu. longipalpis (90,26%) e Lu. whitmani (7,65%). Na zona urbana a abundância de flebotomíneos foi maior no período chuvoso, e na zona rural na estação seca. Lu. longipalpis e Lu. Whitmani ocorreram nas duas estações, com mais frequência na estação chuvosa e seca, respectivamente. Do total de 3.520 fêmeas, 982 exemplares foram utilizados para a extração de DNA e PCR-RFLP para detecção de presença de Leishmania. O vetor Lu. longipalpis foi encontrado infectado por Le. infantum (3,0%), Le. shawi (0,3%), Le. mexicana (0,2%), Le. braziliensis (0,6%) e Le. guyanensis (0,6%) e com infecção mista Le. infantum/Le. braziliensis (0,6%). A espécie Lu. whitmani estava infectada com Le. infantum/Le. braziliensis (4,0%) e Le. braziliensis (4,3%). Outras espécies encontradas infectadas incluem-se: Lu. trinidadensis com Le. infantum/Le. braziliensis; Lu. evandroi e Lu. termitophila com Le. braziliensis e, Le. guyanensis, respectivamente. Para detecção da fonte alimentar foram utilizadas 778 fêmeas ingurgitadas, 573 positivaram para oito tipos diferentes de animais domésticos e silvestres, sendo detectadas reações simples representadas por sange de: cão, homem, galinha, boi, porco, cavalo, roedor e gambá e as reações mistas foram representadas por sangue de: cão/roedor, roedor/homem, galinha/homem, galinha/roedor, cão/galinha, cavalo/roedor, roedor/porco e homem/gambá. A presença de espécies de flebotomíneos infectadas com diferentes espécies de leshmânias e alimentados com sangue de animais domésticos e humanos justifica a ocorrência de forma endêmicas das leishmanioses visceral e tegumentar no município de Caxias. Diante dos resultados obtidos sugere-se adoção de medidas de controle por parte das autoridades de saúde pública, de forma a conter uma futura epidemia dessas doenças.

Le filtrage matriciel, obtenu par projection sur le premier vecteur propre de la matrice spectrale, constitue un outil performant pour l'etude de profils sismiques. C'est un traitement multidimensionnel assez simple a mettre en uvre et qui, par amelioration du rapport signal sur bruit, permet de mettre en evidence les arrivees d'energie caracterisant les structures geologiques. La methode necessite peu d'hypotheses a priori; elle est basee sur les relations frequentielles entre signaux dont la fonction de transfert est definie par le premier vecteur propre de la matrice. L'application a differents profils ecors et leur interpretation structurale permettent de cerner les performances et les limites de la methode: le traitement de profils de reflexion grand angle (campagne preliminaire ecors alpes 85) est peu efficace a cause du caractere tres bruite des donnees; par contre, le traitement de sections de type grands profils donne de bons resultats (profils de reflexion verticale et de reflexion grand angle ecors alpes 86, profil de refraction ecors nord de la france)

Leishmaniasis are a group of neglected infectious and parasitic diseases, with major repercussions at global and national level. In the State of Maranhao, both the American Cutaneous Leishmaniasis (LTA) and the American Visceral Leishmaniasis (LVA) are endemic and have great prominence at the national scene. Within the state territory, one of the leading regions is the Lençóis Maranhenses National Park - PNLM, whose surroundings have undergone environmental and ecological damage caused by man, resulting from direct and indirect tourism activities. As a result of this process every year are recorded cases, mostly LTA ones. Goals. Facing such reality, this study aimed: to define the epidemiological profile of the LTA between the years 2007 and 2013, taking into account demographic (age and gender), occupational and chronological features of the affected populations (reported cases); to demonstrate through a cartographic tool, a survey of the timeline distribution of cases of LTA; and an interactive map to determine the risk rate for acquisition of LT. It has been also proposed to study the transmission cycle of the disease, based on the identification of species of sandflies, their sources of blood and their Leishmania genus parasites, and additionally determining vector capacity of Lu. Whitmani toward Le. Braziliensis and Le. Amazonians. Methodology. The county of Barreirinhas was selected for this study because it is the main gateway to PNLM. In short, investigation of LTA cases was carried out in SINAN files, comprising all neighborhoods of the county (158), through the cycle 2007-2013, and sandflies collections were held in 62 of these communities. The species were identified taxonomically and females analyzed at the molecular level to research for natural infection by Leishmania, along with the animals that served as a food source. Results. 458 positive cases of LTA were reported between the years 2007 and 2013, predominantly in men from rural areas and farmers. The cases were concentrated in the south central area of the county, all year round. There was some geographic expansion with the emergence of new outbreaks, however, it was observed the persistence of the former areas of occurrence of the disease. As for the risk rates, villages Sítio Barra, Engenho and Manoelzinho were those who were positive for all variables. On the other side, the communities Quebra, Santa Rosa and Fumaça, presented less risk, since almost all the variables studied were negative for these locations. As for the sandflies, 9,853 specimens of 18 species have been collected, all present in extra-domicile (forest) and only 12 occurring in peri-domicile areas. The incidence was higher in areas surrounding dwellings (56.2%) than in extra-domicile environment (43.8%) and females predominated (51.4%) over males (48.6%). The dominant species were Lu. whitmani (53.83%), Lu. longipalpis (25.60%), Lu. Lenti (11.69%), Lu. evandroi (5.50%) and Lu. flaviscutellata (0.87%). Natural infections due to Le. infantum, were found in females captured in peri-domicile in five villages and extra-domicile in other two. The species Lu. longipalpis, vector of Le. Infantum, indicated a positivity rate of 3.7% for this species. While species not considered insect vector of this leishmania, such as Lu. Lenti and Lu. Whitmani, even so presented infection rates of 0.6% and 0.9%, respectively. Rates of natural infection due to Le. braziliensis, were detected in peri-domicile in two locations; while in Lu. Whitmani, considered the vector of this Leishmania species, rate of 0.3% was found. The rate of infection due to Le. amazonensis was 8% for Lu. Flaviscutelata, captured in peri-domicile in two villages and extra-domicile in just one. Lu. whitmani was able to get infected with Le. Braziliensis and Le. Amazonians. Concerning food source hosts, the following were identified: equines (9.0%), human (1.4%), canine (27.4%), rodent (3.3%), fowl (20.9%) and hogs (37.9%). Conclusion. All elements of the epidemiological chain of Leishmaniasis were present within the area of study, both in peri-domicile and extra-domicile areas, which explains the endemic state of the disease in the region.
Introdução. As leishmanioses constituem um grupo de doenças infectoparasitárias negligenciadas, com grande repercussão a nível mundial e nacional. No Estado do Maranhão tanto a Leishmaniose Tegumentar Americana (LTA) como a Leishmaniose Visceral Americana (LVA) são endêmicas e apresentam grande destaque no cenário nacional. Dentro do território maranhense, uma das regiões de destaque é a do Parque Nacional dos Lençóis Maranhenses – PNLM, cujo entorno, tem sofrido danos ambientais e ecológicos gerados pelo homem, em função das atividades diretas e indiretas do turismo. Como resultado desse processo todos os anos são registrados casos, principalmente de LTA. Objetivos. Diante desta realidade, este trabalho objetivou definir o perfil epidemiológico da LTA entre os anos de 2007 e 2013, levando em consideração os fatores demográficos (faixa etária e sexo), ocupacionais e temporais das populações acometidas (casos notificados); demonstrar através de uma ferramenta cartográfica, um mapa da distribuição espaço temporal dos casos de LTA e um mapa interativo para determinação da taxa de risco para aquisição da LT. Também se propôs estudar o ciclo de transmissão da doença, a partir da identificação das espécies de flebotomíneos, de suas fontes de sangue e de seus parasitas do gênero Leishmania, e determinar capacidade vetorial de Lu. whitmani para Le. Braziliensis e Le. Amazonenses. Metodologia. O município de Barreirinhas foi selecionado para esse estudo porque constitui a principal porta de entrada ao PNLM. Em suma, fez-se o inquérito dos casos da LTA nos arquivos do SINAN de todas as localides do município (158), no período de 2007-2013, e realizou-se coletas de flebotómineos em 62 destes povoados. As espécies foram identificadas taxonomicamente e as fêmeas analisadas a nível molecular para pesquisa de infecção natural por Leishmania e dos animais que serviram como fonte alimentar. Resultados. Foram notificados 458 casos positivos de LTA entre os anos de 2007 e 2013 predominando nos homens provenientes da zona rural e lavradores. Os casos estavam concentrados na região centrosul do município, ao longo dos anos. Houve certa expansão geográfica com o surgimento de novos focos, entretanto, foi observada a persistência das antigas áreas de ocorrência da doença. Quanto às taxas de risco, os povoados Barra do Sitio, Engenho e Manoelzinho foram os que apresentaram positividade para todas as variáveis estudadas. Já os povoados Quebra, Santa Rosa e Fumaça, ofereceram menor risco, uma vez que, quase todas as variáveis estudadas deram negativas para essas localidades. Quanto aos flebotomíneos, foram coletados 9.853 exemplares de 18 espécies, todas presentes no extradomicílio (mata) e apenas 12 ocorreram nos peridomicílios. A abundância foi maior no peridomicílio (56,2%) do que no extradomicílio (43,8%) e as fêmeas predominaram (51,4%) sobre os machos (48,6%). As espécies dominantes foram Lu. whitmani (53,83%), Lu. longipalpis (25,60%), Lu. lenti (11,69%), Lu. evandroi (5,50%) e Lu. flaviscutellata (0,87%). As infecções naturais por Le. infantum, foram encontradas em fêmeas capturadas nos peridomicílios de cinco povoados e no extradomicilio de outros dois. A espécie Lu. longipalpis, vetora de Le. infantum, mostrou uma taxa de positividade de 3,7% para esta espécie. Enquanto espécies não consideradas vetoras desta leishmânia, como Lu. lenti e Lu. whitmani mostraram taxas de infecção de 0,6% e 0,9%, respectivamente. A taxa de infecção natural por Le. braziliensis, foi detectada nos peridomicílios de duas localidades; para Lu. whitmani, considerada vetora desta espécie de Leishmania foi encontrada taxa de 0,3%. A taxa de infecção por Le. amazonensis foi de 8% para Lu. flaviscutelata obtidos nos peridomicilios de dois povoados e no extradomicilio de um apenas. Lu. whitmani foi capaz de se infectar com Le. Braziliensis e Le. Amazonenses. Para fonte alimentar foram identificados os seguintes hospedeiros: equino (9,0%), humano (1,4%), cão (27,4%), roedor (3,3%), galinha (20,9%) e porco (37,9%). Conclusão. Todos os elementos da cadeia epidemiológica das leishmanioses estavam presentes na área do presente estudo, tanto no peridomicílio como no extradomicílio, o que explica a situação endêmica da doença na região.

Nous pouvons appréhender le Cinéma comme un vecteur culturel capable de cristalliser les us et coutumes d’une société, ou comme un outil susceptible d’en manifester les aspirations. L’industrie cinématographique italienne demeure parmi celles qui ont su imposer dans l'imaginaire des publics des œuvres venues aussitôt enrichir le patrimoine culturel mondial. De nos jours, sa présence internationale est plus modérée, et le rayonnement de ses œuvres ne dépasse que rarement les limites nationales. Les quelques auteurs tels que Emanuele Crialese, Matteo Garrone et Paolo Sorrentino ont su gagner une visibilité désormais incontestable, leur permettant de devenir le symbole d’un cinéma italien contemporain renaissant. Les contenus de leurs filmographies sont le résultat de formes cinématographiques tout aussi riches que variées, et leur influence semble capable de modifier et de mettre à jour l’imaginaire des passionnés de culture italienne. Nos travaux veulent étudier et comprendre l’impact de leurs œuvres au sein d’un pays comme la France. À travers une étude qui se veut historique, sociologique et économique, nous analysons la représentation du réel dans l’histoire du cinéma transalpin, un idéal intellectuel qui semble intéresser particulièrement les publics français. Puis nous nous consacrons aux contenus de nos trois filmographies de référence, pour en extrapoler les données socio-politico-économiques. L’étude de l’impact de ces œuvres sur les critiques cinématographiques français conclut ces travaux, qui se penchent également sur la distribution et l’exploitation de ce cinéma, présent non seulement dans les salles de l'Hexagone, mais diffusé parallèlement au sein de nombreux festivals
One may approach cinema as a cultural vector which can either give shape to the habits and customs of a given society or reflect its yearnings. The Italian film industry is one among those which have produced movies which entered the global cultural imaginary. Nowadays, its international presence has been reshaped and Italian films do not easily shine beyond the national frame. Artists such as Emanuele Crialese, Matteo Garrone or Paolo Sorrentino have managed to achieve an undeniable visibility, and have become the symbol of a reborn contemporary Italian cinema. The content of their filmographies are the result of film shapes that are as rich as they are diverse, and their influence seems able to alter and to update the imaginary of italian culture connoisseurs. The purpose of our work is to study and understand the impact of their masterpieces on the French audience. Through a historical, sociological and economical study, we will analyse the representation of reality in the history of Italian cinema : an intellectual ideal which seems to have been of interest especially to the French spectators. Then we will focus on the content of these three specific directors’ lifework in order to examine social, political and economical data. Finally, we will conclude by observing the impact these films have had on French experts such as film critics. This study also deals with the distribution and the running of these specific directors’ films not only in the cinemas but also when aired in various film festivals
È possibile concepire il Cinema come un vettore culturale capace di materializzare gli usi e i costumi di una società, o suscettibile di manifestarne le aspirazioni. L'industria cinematografica italiana dimora tra quelle che hanno saputo imporre delle opere entrate istantaneamente nell'immaginario collettivo, e ciò su scala mondiale. Oggi, la sua presenza a livello internazionale è stata ridimensionata e la diffusione delle sue opere oltrepassa raramente i confini nazionali. I rari autori del calibro di Emanuele Crialese, Matteo Garrone e Paolo Sorrentino hanno saputo acquisire una visibilità oramai indiscussa, permettendo loro di diventare il simbolo d'un cinema italiano contemporaneo rinascente. I contenuti delle loro filmografie sono il risultato di forme cinematografiche tanto ricche quanto varie, e la loro influenza sembra capace di modificare e aggiornare l'immaginario degli appassionati di cultura italiana. Queste ricerche vogliono analizzare e comprendere l'impatto delle loro opere in un paese come la Francia. Attraverso degli studi storici, sociologici ed economici, queste ricerche analizzano le forme rappresentative legate al reale presenti nella storia del cinema italiano, un ideale intellettuale che sembra interessare in particolar modo i pubblici francesi. Inoltre, esse si consacrano all'estrapolazione dei dati socio-politico-economici contenuti nelle tre filmografie a cui facciamo riferimento. L'analisi dell'impatto di queste opere sui critici cinematografici francesi scelti come pubblici, concludono queste ricerche che si dedicano in egual modo alla distribuzione e alla commercializzazione di queste opere, presenti non solo in sala, ma diffuse inoltre in molti festival

ABSTRACT Study of vector fonts seal carving This research paper is mainly about the use of CO2 laser carving cutter in engraving of common images and fonts. The method is to take a ready typesetting of a graphic file and run it through the developed path. By utilizing the path tracing method, the system will capture the internal and external vector data of the font, and after repeating the same steps, the path gradually makes move outward and inward until the engraving area are all filled. The lattice fonts will be transformed into vector fonts, and then all the fonts can easily and freely to be shrinked or enlarged. At the last, to process the captured data and have it reprogrammed. As soon as the new data is sent to the interpreter, the dual-axis drive motor proceeds the engraving(the images or fonts). By doing the mentioned steps, not only the efficiency and finesse of engraving will be improved, but also the quality, speed and stability of engraving will be highly promoted. Keywords：Vector font, Path Planning, Laser engraving,Contour capture.

Idiopathic congenital clubfoot can be treated either operatively (comprehensive surgical release (CSR)) or conservatively (ponseti technique (PCT)). This thesis compared the mid-term outcomes after CSR and PCT treatments to a typically developing sample. A Dynamical Systems Analysis (DSA) approach and a multi-segment foot model were used to examine group differences in multi-segment foot and lower extremity kinematics, kinetics, coordination and coordination variability during walking. Ten children with clubfoot treated with PCT and seven children with clubfoot treated with CSR were evaluated retrospectively and compared to ten typically developing children. Multi-segment foot and lower extremity kinematic (240 Hz) and kinetic (1080 Hz) data were collected while participants walked barefoot at a fixed walking velocity (1.0 m/s-1 ±5%). Sagittal plane metatarsophalangeal (MTP) and three-dimensional (3D) forefoot-rearfoot, ankle, knee and hip joint range of motion (ROM) during stance and 3D ankle, knee and hip peak joint moments during push-off were calculated. A modified vector coding technique was used to quantify the multi-segment foot and lower extremity coordination and coordination variability throughout stance for forefoot-rearfoot inversion/eversion (Ff-Rf), rearfoot inversion/eversion–tibial internal/external rotation (Rf-Tib) and femur-tibia internal/external rotation (Fem-Tib) couples. Reduced MTP and forefoot-rearfoot ROM was observed in the CSR group while the PCT group demonstrated values comparable to CTR. Sagittal plane ankle ROM was similar between groups however, the CSR group demonstrated reduced frontal plane ROM compared to PCT. Peak ankle plantar flexion moment was reduced in the last 50% of stance in the clubfoot groups. The CSR group demonstrated greater knee and hip moments compared to CTR and PCT. The PCT group demonstrated lessor peak ankle eversion, knee external rotation and knee valgus moments compared to CTR. No significant differences were observed in Ff-Rf, Rf-Tib and Fem-Tib coordination and coordination variability throughout stance between the groups. PCT and CSR gait was characterized by restricted multi-segment foot motion and abnormal lower extremity joint moments; suggesting mild residual deformity. Despite residual deformity, the coordination and coordination variability results indicate that the PCT and CSR groups are not functionally limited and demonstrate similar multi-segment foot and lower extremity movement patterns as CTR.

Foot-and-mouth disease virus (FMDV) is a constant threat to domestic livestock throughout the world. The outbreak of FMD has led to huge economic loss in affected countries. The conventional vaccine against FMDV is based on the chemically inactivated virus. This remains a potential risk of virus escape by biosecurity failure or incomplete viral inactivation. Therefore, alternative approaches to produce an efficient and safe FMDV vaccine are needed to circumvent the use of inactivated virus. Development of plant virus-based vaccines has several advantages, such as easy to produce, low cost and safe. Advances in understanding the mechanism of immune response in molecular level have led to the successful design and production of FMDV vaccines using different expression systems. The prominent G—H loop of the VP 1 capsid protein of FMDV spanning residues 134—158 has been identified as a major immunogenic site for eliciting neutralizing antibodies and has formed the basis for the peptide approach to vaccination. Bamboo mosaic virus (BaMV), a member of the potexvirus, is a single-stranded, positive-sense RNA virus with a genome size about 6.4 kb which contains five conserved open reading frame (ORFs). In this study, the immunogenic dominant epitope of FMDV was expressed in Chenopodium quinoa using a vector based on a recombinant Bamboo mosaic virus (BaMV). The recombinant virus BS-FMDV-VP1128164-Nd35mcp (Vd35mCP) contains 37 amino acid residues from G-H loop fused to the amino terminus of BaMV capsid protein (CP). Vd35mCP infected C. quinoa produced large quantity of stable progeny viral particles assembled with the modified CP subunits. Mice and guinea pigs were used to test the immunogenic effects of the recombinant virus. All mice produce high serum tilter after parenteral injection with different dose of Vd35mCP, or the overexpressed VP1 protein in E. coli. However, oral administration of the Vd35mCP to guinea pigs cannot elite high serum IgG against FMDV, which remains further investigation.

Dissertação de mestre em Engenharia Eletrónica Industrial e de Computadores
A emissão de gases poluentes para a atmosfera tem vindo a provocar alterações climáticas irreparáveis, levantando inúmeras questões relativas ao desenvolvimento sustentável para o futuro que se avizinha. Entre outros, a mobilidade de pessoas e bens apresenta-se como uma das principais origens deste problema. Com o intuito de mitigar este problema, a mobilidade elétrica tem vindo a ter uma presença cada vez mais assídua na sociedade de hoje em dia, proporcionando um meio de transporte com zero emissões. Contudo, a maior desvantagem deste conceito reside no sistema de armazenamento de energia, usualmente baterias eletroquímicas, resultando em autonomias baixas e tempos de carregamento elevados. Com o intuito de contribuir com o desenvolvimento tecnológico nesta área de investigação, o objeto de estudo desta dissertação teve como foco principal os sistemas de carregamento de baterias. No presente documento de dissertação de mestrado são apresentados vários tipos de carregamento de baterias existentes no mercado, os seus princípios de funcionamento, bem como vantagens e desvantagens. Tendo em consideração estes últimos pontos, e com o intuito de contribuir com o desenvolvimento tecnológico nesta área, foi desenvolvido um conversor de eletrónica de potência para o carregamento de baterias de um veículo elétrico. O carregador de eletrónica de potência desenvolvido é trifásico de carregamento lento e unidirecional, tendo sido adotada uma topologia em fonte de corrente, possuindo uma bobina como elemento armazenador de energia, em vez dos típicos condensadores aplicados aos conversores do tipo fonte de tensão. Além das diferenças mencionadas anteriormente, o conversor fonte de corrente permite ajustar de forma dinâmica a corrente de carregamento da bateria, evitando o uso de um segundo conversor CC-CC para esse efeito. Foi utilizado um sistema de controlo para o conversor funcionar como carregador de baterias que tem com base a modulação vetorial. O estudo e validação teórica do conversor de eletrónica de potência para o carregamento das baterias foi realizada com a ajuda da ferramenta de simulação PSIM. O desenvolvimento do protótipo e consequente validação experimental foi realizado em ambiente laboratorial, onde dispunha dos materiais e equipamentos necessários para a realização deste projeto.
The emission of gaseous pollutants into the atmosphere has been causing irreparable climate change, raising several issues regarding sustainable development for the near future. Among others, mobility presents itself as one of the main origins of this problem. In order to mitigate this problem, electric mobility has been an increasingly frequent presence in today's society, providing a means of transportation with zero emissions. However, the major disadvantage of this concept lies in the energy storage system, usually electrochemical batteries, imposing low autonomy and high charging times. To contribute to the technological development in this area of research, the study object of this dissertation was focused on battery charging systems. In this Master Dissertation document are presented various types of battery charging systems existing in the market, its operating principles as well as advantages and disadvantages. Taking into consideration these last points, and with the intention of contributing to the technological development in this area, it was developed a power electronics converter to charge electric vehicle batteries. The developed power electronics converter is a three-phase, slow charging unidirectional device, with a current source topology having a coil as energy storage element instead of the typical capacitors applied in voltage source converters. In addition to these differences, the current source converter allows to dynamically adjust the battery charging current, avoiding the use of a secondary DC-DC converter for this purpose. A control system adapted to the converter was used, the main one being based in the space vector modulation. The study and theoretical validation of the power electronic converter for battery charging was carried out with the help of the PSIM simulation tool. The development of the prototype and consequent experimental validation was performed in laboratory environment, where it had the necessary components and instruments for the realization of this project.

Atualmente, a utilização de cargas não lineares é cada vez mais frequente. Estas, originam problemas de qualidade de energia elétrica (QEE), resultando em várias consequências, como falhas em equipamentos eletrónicos, podendo causar prejuízos elevados em diversos setores. Os filtros ativos de potência, que também podem fazer interface com fontes de energia renovável, apresentam-se como uma boa solução para mitigar estes problemas. Nesta dissertação de mestrado apresentam-se as topologias de filtros ativos de potência, tendo sido simulada uma topologia de Filtro Ativo Paralelo do Tipo Fonte de Corrente. Nesta simulação, para além do inversor fonte de corrente (Current-Source Inverter - CSI), implementou-se um algoritmo baseado na Teoria p-q, bem como a técnica de modulação vetorial (Space-Vector Modulation - SVM). Estas técnicas foram as escolhidas para efetuar o controlo e a modulação do Filtro Ativo Paralelo do Tipo Fonte de Corrente. Nesta dissertação é ainda efetuado um estudo sobre o estado da arte dos conversores CC-CC utilizados em sistemas solares fotovoltaicos, e sobre os sistemas de controlo aplicáveis aos mesmos.

A Qualidade de Energia Elétrica é um assunto cada vez mais importante devido ao crescente número de problemas e custos relacionados com a diminuição dos níveis de Qualidade de Energia Elétrica. Para compensar os atuais problemas de Qualidade de Energia Elétrica foram desenvolvidos os filtros ativos de potência, que possuem uma resposta temporal rápida, sendo capazes de se adaptar dinamicamente às condições do sistema que estão a compensar. Nesta Dissertação de Mestrado são apresentadas as principais topologias de filtros ativos de potência, sendo que a utilizada foi o Filtro Ativo Paralelo. Esta é considerada uma das mais importantes, por ser capaz de efetuar compensações a nível das correntes. Para a implementação deste filtro ativo de potência foi necessário definir o tipo de inversor, a teoria de controlo e a técnica de modulação a serem utilizadas. Tendo isto em conta, foi efetuado o levantamento do estado da arte relativo aos inversores utilizados em filtros ativos de potência, assim como das principais teorias de controlo e técnicas de modulação aplicáveis no âmbito desta Dissertação. Após isto, foi selecionado o Inversor Tipo Fonte de Corrente (Current-Source Inverter - CSI). A teoria de controlo e a técnica de modulação escolhidas foram, respetivamente, a Teoria p-q e a Modulação Vetorial (Space Vector Modulation - SVM). O sistema de controlo e os circuitos de potência foram simulados no software PSIM para que seja possível validar a sua correta implementação e funcionamento. Uma vez obtida essa validação, os circuitos e sistemas de controlo foram implementados em laboratório, para verificar o seu funcionamento. Finalmente, é de referir que com esta Dissertação pretende-se contribuir para a investigação da utilização de Inversores Tipo Fonte de Corrente em Filtros Ativos Paralelos.
Power Quality is a subject with ever increasing importance due to the rising numbers of problems and costs related with the reduction of the Power Quality levels. To compensate the Power Quality problems were developed active power filters that have a quick time response, and that are capable of adapting to the conditions of the system they are compensating. In this Master Thesis are presented the main topologies of active power filters, with the Shunt Active Power Filter being implemented. This topology is considered to be one of the most important active power filter topologies, because it is capable of performing current compensation. For the implementation of this active power filter, it was necessary to define the type of inverter, the control strategy and the modulation technique to be used. Regarding this, a research of the state of the art of inverters, control strategies and modulation techniques used in Shunt Active Filters was performed. After this, the Current-Source Inverter (CSI) was selected. The control strategy and the modulation technique implemented were the p-q Theory and the Space Vector Modulation (SVM), respectively. The control and power circuits were simulated using the software PSIM, so that their operation could be validated. Once this validation was obtained, these systems were implemented in laboratory, to assess their operation capabilities. Finally, it must be said that with this work it is intended to contribute to the research of the use of Current Source Inverters in Shunt Active Power Filters.
