A measurement method of small-capacitance using transient waveforms is proposed in this thesis. A pi-circuit is used to express the stray capacitors between terminals and those from each terminal to ground. Two measuring modes, differential and common modes, are required to obtain the parameters of the circuit. The parameters are determined by transient current waveforms of the modes with an applied voltage, i.e., the open circuited voltage at the end of the current injection cable. The parameters of the pi-type circuit are obtained from a slope of the transient current waveforms or a waveform fitting by a nonlinear method. These methods enable the derivation without a voltage measurement by a probe connecting across the small capacitance, since the parasitic capacitance of the voltage probe obscures the small capacitance. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University

A população de cães errantes tem sido um problema na sociedade moderna e levanta discussão sobre o bem estar dos animais, a responsabilidade ambiental e assuntos relacionados saúde pública, como agressão, zoonoses e acidentes de trânsito. São Paulo é uma cidade com mais de dez milhões de habitantes e uma população de cães domiciliados em torno de 2,5 milhões de animais. Não há pesquisas a respeito da distribuição da população de cães errantes e isso dificulta o planejamento de ações de intervenção neste campo. O problema foi abordado do ponto de vista da probabilidade de abandono e capacidade de suporte ambiental. Foi criado um escore composto por treze variáveis de risco de abandono. Os dados foram agrupados por distrito administrativo e estes classificados em três categorias (tercis). Foi definida uma amostra de conveniência de seis áreas a serem visitadas, duas em cada categoria, que fossem pequenas e isoladas, passiveis de percorrer a pé. O número de animais foi estimado pelo método de pseudo-captura, utilizando fotos e anotações para identificar os animais. Simultaneamente, foi aplicado um questionário em uma amostra aleatória sistemática dos domicílios de cada área. Das seis áreas visitadas, em duas foi observada presença de cães errantes e em apenas uma delas, uma população fixa. Dos fatores associados a presença de cães errantes, destacam-se os relacionados a proximidade homem-cão e ao ambiente. Intervenções nestes fatores e incentivo à guarda responsável podem ser soluções desejáveis para redução gradativa da população de cães errantes / The stray dog\'s population of has been a problem in modern society and raises discussion on different issues like animal welfare, environmental responsibility and public health matters such as dogs bites, zoonosis and traffic accidents. Sao Paulo is a city with over ten million inhabitants and a population of owned dogs around 2.5 million animals. There are no surveys on the distribution of the population of stray dogs and this hampers any plan of intervention. The problem was accessed from the standpoint of relinquishment probability and environmental carrying capacity. A score was created with thirteen variables, of known risk factors of relinquishment. The data was grouped by district and classified in to three categories (terciles). a convenience sample of six areas was defined, two in each category, which were small and isolated, liable to go through on foot. The number of animals was estimated by the pseudo capture method, using photos and notes to identify the animals. Simultaneously, a questionnaire was administered in a systematic random sample of households in each area. Of the six areas visited, in only two it the presence of stray dogs was observed and only one showing a fixed stray population. Of the factors associated to the presence of stray dogs, one can distinguish: degree of human-dog proximity and those related to environment. Intervention on these factors and encouraging responsible ownership could be a solution to gradually reduce the population of stray dogs.

Abstract The dissertation examines the settlement and interactions of the Late Iron Age communities of northern Finland by focusing on the archaeological sites and finds documented in the regions of Northern Ostrobothnia and Kainuu. The point of departure for the study is to understand the data from a local point of view as in the previous evaluations the hunter-gatherer population inhabiting the area has been overlooked with most of the discussions revolving around the peasant influence arriving from southwestern Finland and Karelia. Partially for this reason, the period in question has appeared problematic and many questions regarding the settlement remain unadressed. The reason for the poor research situation articulates with the problems related to the archaeologica remains. Most of the material must be classified as so-called stray finds or archaeological objects to which no context can be determined without excavations taking place. These stray finds comprise the most significant portion of the available data, as besides them only a few burials, dwelling sites or other feasible remains are documented in Northern Ostrobothnia and Kainuu. In spite of this, the research interest towards these finds has been relatively minor until recent years. The research questions are approached via three case studies, which represent stray finds that were excavated during the research process of the dissertation. These sites are addressed by taking into consideration their form, function and dating as well as examining their archaeological context on a borader geographical scale. In addition to the case studies, the dissertation considers previously known sites and finds in the research area and elsewhere in the interior and northern Fennoscandia. Based on the study, it is argued that several stray finds are associated with burial sites, dwellings and other indicators of settlement whose formation process has likely been affected by local traditions and subsistence as well as contacts and interactions with other Iron Age communities. / Tiivistelmä Tutkimus tarkastelee Pohjois-Suomen myöhäisrautakautista asutusta ja väestön vuorovaikutussuhteita Pohjois-Pohjanmaan ja Kainuun maakuntien alueelta tunnettujen löytöjen ja kohteiden valossa. Tutkimuksen keskeisimpänä lähtökohtana on näiden teemojen hahmottaminen paikallisesta näkökulmasta, sillä monissa aikaisemmissa tulkinnoissa alueella asunut metsästäjä-keräilijäväestö on jäänyt kohtalaisen vähäiselle huomiolle keskustelujen keskittyessä Lounais-Suomesta ja Karjalasta tulleeseen talonpoikaisvaikutukseen. Osittain tästä syystä kyseinen aikakausi on pitkään näyttäytynyt ongelmallisena, eikä moniin alueen asutusta koskevaan kysymykseen ole voitu vastata. Syy myöhäisen rautakauden heikkoon tutkimustilanteeseen niveltyy arkeologiseen aineistoon liittyvään problematiikkaan. Valtaosa tutkimusalueelta talletetusta materiaalista on luettava niin kutsutuiksi irtolöydöiksi, eli arkeologisiksi esinelöydöiksi, jolle ei ilman kenttätutkimuksia ole mahdollista määrittää tarkkaa löytöyhteyttä. Irtolöydöt muodostavat merkittävän aineistokokonaisuuden, sillä niiden lisäksi Pohjois-Pohjanmaalta ja Kainuusta tunnetaan ainoastaan muutamia myöhäisrautakautisia asuinpaikkoja, hautoja tai muita arkeologisia kohteita. Tästä huolimatta, niihin kohdistunut tutkimuksellinen mielenkiinto on viimevuosiin saakka ollut pääosin vähäistä. Väitöskirja lähestyy aineistoa kolmen tapaustutkimuksen kautta. Tapaustutkimukset koostuvat kaivauksin tutkituista irtolöytökohteista sekä niiden lähiympäristön sekä laajemman arkeologisen kontekstin havainnoinnista. Kaivauksin tutkittujen kohteiden lisäksi tutkimuksessa tarkastellaan myös muuta myöhäiselle rautakaudelle ajoittuvaa aineistoa niin tutkimusalueella kuin sen lähialueilla. Tutkimuksen perusteella useat irtolöydöt voidaan liittää hautoihin, asuinpaikkoihin tai muihin asutuksesta kertoviin muinaisjäännöksiin, joiden muodostumisprosessiin ovat vaikuttaneet niin paikalliset traditiot ja elinkeinot kuin yhteydet ja vuorovaikutus muiden rautakautisten yhteisöjen kanssa.

The cat is capable of the elimination of millions of oocysts in the environment leading to a massive contamination of these places and leading to a public health issue. Toxoplamosis is a disease with high prevalence throughout the world and the cat is responsible for the parasite’s perpetuation. The evaluation of the accuracy of parasitological diagnostic methods is of vital importance to improve the veterinarian laboratory diagnosis through the use of high sensitivity, specificity and reproducible tests. The aim of this study was to verify the prevalence of intestinal parasites from stray cats in Goiania-GO, to verify the seroprevalence of anti-T. gondii antibodies through the modified aglutination test (MAT) and to perform the evaluation of the accuracy of the parasitological tests applied. Therefore 155 samples of feces and 50 blood samples from stray cats from the Zoonosis Center of Goiania were collected during the year of 2012. The feces samples were processed by the Willis (gold standard), Sheather, Faust and Hoffman-Janer-Pons-Lutz (HJPL) techniques. The MAT was performed in the blood samples. The accuracy was performed through the determination of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and kappa index (k). The intestinal parasites prevalence in the feces from stray cats was 71.68% (115/154). The most prevalent helminth was Ancylostomatids (83.48%, 96/115) and the most prevalent protozoan in monoparasitism was Cystoisospora sp (7.83%, 9/115). T. gondii presented high prevalence (18.27%, 21/115) in fecal samples, 64% in blood samples (32/50) while 36% seronegative (18/50). The accuracy showed that the HJPL and Sheather techniques presented association to the golden standard for the intestinal parasites diagnosis. For the specific diagnosis of T. gondii oocysts the Faust techniques was the one with high accuracy in comparasion to the golden standard, with we emphasize the importance of using two parasitological techniques for the diagnosis of intestinal parasites / O gato doméstico é um importante transmissor de agentes zoonóticos para o homem, em especial Toxoplasma gondii. O gato infectado é capaz de eliminar milhões de oocistos no meio ambiente, provocando uma contaminação maciça nestes locais, sendo considerado um problema de saúde pública. A toxoplasmose é uma doença com alta prevalência em todo o mundo, sendo o gato responsável pela perpetuação do parasito. Avaliar a acurácia de métodos parasitológicos é de extrema importância para melhorar o diagnóstico laboratorial veterinário, utilizando testes de alta sensibilidade, especificidade e reprodutibilidade. O objetivo deste trabalho foi verificar a prevalência de parasitos intestinais em gatos errantes em GoiâniaGO, verificar a soroprevalência de anticorpos anti-T. gondii pelo teste de aglutinação modificado (MAT) e realizar a avaliação da acurácia de técnicas parasitológicas aplicadas no diagnóstico de parasitos intestinais. Foram coletadas 155 amostras de fezes no ano de 2012 no Centro de Controle de Zoonoses de Goiânia-GO e 50 amostras de sangue de gatos no mesmo período. As amostras de fezes foram processadas pelos métodos de Willis (padrão-ouro), Sheather, Faust e Hoffman-Janer-Pons-Lutz (HJPL). Nas amostras de sangue foi realizado o MAT. A análise de acurácia foi realizada determinando a sensibilidade, especificidade, valor preditivo positivo (VPP), valor preditivo negativo (VPN) e índice kappa (k). A prevalência de parasitos intestinais no ano de 2012 foi de 71,68% (115/154), sendo os Ancilostomídeos o helminto mais prevalente 83,48% (96/115), o protozoário mais prevalente foi Cystoisospora sp. em monoparasitismo 7,83% (9/115). T. gondii apresentou alta prevalência: 18,27% (21/115). Ao analisar a soroprevalência de um grupo de 50 animais, 64% (32/50) eram soropositivos e 36% (18/50) soronegativos. A análise de acurácia demonstrou que as técnicas de HJPL e Sheather apresentaram associação ao padrão-ouro para o diagnóstico de parasitos intestinais. No diagnóstico específico de oocistos de T. gondii a técnica de Faust apresentou melhor acurácia comparada ao padrão-ouro, com isso ressaltamos a importância do uso de duas técnicas parasitológicas para o diagnóstico de parasitos intestinais.

Les doses secondaires neutroniques ne sont actuellement pas estimées lors de la planification de traitement dans les centres de protonthérapie puisque les logiciels de planification de traitement (TPS) ne le proposent pas tandis que les simulations Monte Carlo (MC) et les mesures sont inadaptées pour un environnement clinique. L’objectif de la thèse est de développer un modèle analytique dédié à l’estimation des doses secondaires neutroniques aux organes sains qui reste pratique et simple d’utilisation en routine clinique. Dans un premier temps, la géométrie existante de la gantry installée au Centre de protonthérapie d’Orsay (CPO) de l’institut Curie modélisée avec le code de calcul MCNPX a été étendue à trois configurations de traitement supplémentaires (énergie en entrée de ligne de 162, 192 et 220 MeV). Une approche comparative simulation-mesure a ensuite été entreprise afin de vérifier la capacité de ces modélisations à reproduire les distributions de doses (en profondeur et latérales) des protons primaires ainsi que le champ secondaire neutronique. Des écarts inférieurs à 2 mm ont été observés pour les protons primaires. Pour les neutrons secondaires, les écarts sont plus mitigés avec des rapports simulation sur mesure de ~2 et de ~6, respectivement pour la spectrométrie et les équivalents de dose dans un fantôme physique. L’analyse des résultats a permis d’identifier l’origine de ces écarts et de mettre en perspective la nécessité de conduire de nouvelles études pour améliorer à la fois les mesures expérimentales et les simulations MC. Dans un deuxième temps, une approche purement numérique a été considérée pour calculer les doses neutroniques aux organes sains de fantômes voxélisés représentant des patients d’un an, de dix ans et adulte, traités pour un craniopharyngiome. Une variation de chaque paramètre de traitement a été réalisée afin d’étudier leur influence respective sur les doses neutroniques. Ces paramètres ont pu être ordonnés par ordre décroissant d’influence : incidence de traitement, distance organe-collimateur et organe-champ de traitement, taille/âge des patients, énergie de traitement, largeur de modulation, ouverture du collimateur, etc. Des suggestions ont également été avancées pour réduire les doses neutroniques.Dans un troisième temps, un modèle analytique a été conçu de façon à être utilisable en routine clinique, pour tous les types de tumeur et toutes les installations de protonthérapie. Son entraînement séparé pour trois incidences de traitement a montré des écarts inferieurs à ~30% et ~60 µGy Gy⁻¹ entre les données d’apprentissage (doses neutroniques calculées aux organes sains) et les valeurs prédites par le modèle analytique. La validation a consisté à comparer les doses neutroniques estimées par le modèle analytique à celles calculées avec MCNPX pour des conditions différentes des données d’apprentissage. Globalement, un accord acceptable a été observé avec des écarts moyens de ~30% et ~100 µGy Gy⁻¹. La flexibilité et la fiabilité du modèle analytique ont ainsi été mises en évidence. L’entraînement du modèle analytique à partir d’équivalents de dose neutroniques mesurés dans un fantôme solide au Centre Antoine Lacassagne a confirmé son universalité, bien qu’il requière néanmoins quelques ajustements supplémentaires pour améliorer sa précision. / Stray neutron doses are currently not evaluated during treatment planning within proton therapy centers since treatment planning systems (TPS) do not allow this feature while Monte Carlo (MC) simulations and measurements are unsuitable for routine practice. The PhD aims at developing an analytical model dedicated to the estimation of stray neutron doses to healthy organs which remains easy-to-use in clinical routine. First, the existing MCNPX model of the gantry installed at the Curie institute - proton therapy center of Orsay (CPO) was extended to three additional treatment configurations (energy at the beam line entrance of 162, 192 and 220 MeV). Then, the comparison of simulations and measurements was carried out to verify the ability of the MC model to reproduce primary proton dose distributions (in depth and lateral) as well as the stray neutron field. Errors within 2 mm were observed for primary protons. For stray neutrons, simulations overestimated measurements by up to a factor of ~2 and ~6 for spectrometry and dose equivalent in a solid phantom, respectively. The result analysis enabled to identify the source of these errors and to put into perspective new studies in order to improve both experimental measurements and MC simulations. Secondly, MC simulations were used to calculate neutron doses to healthy organs of a one-year-old, a ten-year-old and an adult voxelized phantoms, treated for a carniopharyngioma. Treatment parameters were individually varied to study their respective influence on neutron doses. Parameters in decreasing order of influence are: beam incidence, organ-to-collimator and organ-to-treatment field distances, patient’ size/age, treatment energy, modulation width, collimator aperture, etc. Based on these calculations, recommendations were given to reduce neutron doses. Thirdly, an analytical model was developed complying with a use in clinical routine, for all tumor localizations and proton therapy facilities. The model was trained to reproduce calculated neutron doses to healthy organs and showed errors within ~30% and ~60 µGy Gy⁻¹ between learning data and predicted values; this was separately done for each beam incidence. Next, the analytical model was validated against neutron dose calculations not considered during the training step. Overall, satisfactory errors were observed within ~30% and ~100 µGy Gy⁻¹. This highlighted the flexibility and reliability of the analytical model. Finally, the training of the analytical model made using neutron dose equivalent measured in a solid phantom at the center Antoine Lacassagne confirmed its universality while also indicating that additional modifications are required to enhance its accuracy.

This diploma thesis deals with the issue of EMC of tram vehicles and traction system. The first chapter defines the issues that are then dealt with in the thesis. The next chapter lists the objectives of the work. Subsequent chapters analyze the issues described in chapter 2. In the last chapter, a flow chart is proposed, which should serve as a tool to estimate the hazards of the traction drive due to induced bearing currents.

<p dir="ltr"> Nowadays, inkjet printers are widely used all around the world. But how do they transfer the digital image to a map that can control nozzle firing? In this preliminary report, we briefly illustrate that part of the printing pipeline that starts from a halftone image and ends with Hardware Ready Bits (HRBs). We also describe the implementation of the multi-pass printing method with a designed print mask. HRBs are used to read an input halftone CMY image and output a binary map of each color to decide whether or not to eject the corresponding coloranr drop at each pixel position. In general, for an inkjet printer, each row of the image corresponds to one specific nozzle in each swath so that each swath will be the height of the printhead \cite{torpey1997multipass}. To avoid visible white streaks due to clogged or burned out color nozzles, the method called multi-pass printing is implemented. Subsequently, the print mask is introduced so that we can decide during which pass each pixel should be printed. Once we figure out how to transfer the digital image to our printing signals. We start to think about improving the color performance for the inkjet printer. In one of our previous papers \cite{wang2020developing}, we described the color management pipeline that was applied to our nail inkjet printer, which is used to map the source gamut to the destination printer gamut. However, the resulting prints are not as vivid as we would like to have, since those prints are not well saturated. To obtain more saturated prints, we propose a saturation enhancement method based on image segmentation and hue angle. This method will not necessarily give us the closest representation of the colors within the input image but could give us more saturated prints. The main idea of our saturation enhancement method is to keep the lightness and hue constant, while stretching the chroma component.</p><p><br></p><p dir="ltr"> In one of our previous papers \cite{hu2021improving}, we mostly focused on the color saturation problem in our inkjet printer. However, our partner reported that there are some boundary noise pixels on the background, which are quite visible when the background is white. By checking the pipeline of our printing procedure, we realized that the noise stray dots are generated during the halftoning procedure. This part of the dissertation is dedicated to separating the white background from the foreground, which enables us to constrain the error diffusion process inside the white background. The main idea is to apply image segmentation, which could help us to precisely extract the background.</p><p><br></p><p dir="ltr"> Lastly, inspired by the paper \cite{smith2023chiral}, we decided to design an aperiodic clustered-dot screen, which may have better performance compared to the current DBS screen. This screen generation method is offline, so the time cost is not our main consideration. The output halftone result is what we concentrate on. This screen is generated based on a polygon shape, which is called tile(1,1) defined by the paper \cite{smith2023chiral}. We keep extending this single polygon shape to obtain the combination aperiodic shape that is called a supertile. After obtaining the final supertile, we assigned each tile(1,1) shape to either a dot or a hole based on the complementary symmetry property. Finally, based on some interpolation methods, we generate the threshold matrix. </p>
