Full textAbstract:
Allteftersom forskningen inom Human Computer interaction (HCI) fortskrider konstrueras det allt fler innovativa sätt att interagera med spelkonsoller. Då fler sätt att interagera med spelkonsoller utvecklas förbättras även förutsättningarna för spelbranschen att öka interaktionen i spelen. Den senaste generationen av spelkonsoller har kommit fram med egna lösningar och innovativa sätt att öka spelupplevelsen och interaktionen. Nintendo Wii har t.ex. en rörelsesensor som reagerar på rörelserna av handkontrollen, och Xbox Kinect reagerar med hjälp av en kamera som läser av kroppens rörelser och Playstation Move reagerar på en kombination av en kamera och en kontroll med sensorer. Handkontrollens design har inte förändrats mycket under de senaste konsol-generationerna om man bortser från Nintendo Wii som formade sin kontroll som en stav. Kontrollen har haft en bumerangform, som med tiden har fått fler knappar och i senare generationer analoga spakar. Kontrollen ligger bra i handen och designen ger en bra spelupplevelse i vissa genrer av spel. I vissa spel ökas interaktionen med tillbehör, som t.ex. musikinstrument för karaokespel som underlättar för spelaren. Undantaget är FPS-genren, där precisionen kompenseras med hjälp av mjukvara. Frågeställningen i denna avhandling är om man med hjälp av en ny handkontrollsdesign i formen av en sfär kan öka precisionen i FPS-spel. Designen avviker från den traditionella, och i kontrollen används modern teknologi för att kunna registrera lutningar av handkontrollen. Med hjälp av intervjuer kan jag utvisa huruvida kontrollen förbättrar precisionen och spelkänslan, och vilka områden som behövs förbättras. Slutsatsen blev att testerna inte var tillräckliga för att rättvist kunna säga om det misslyckades eller lyckades då respondenterna som var missnöjda med känsligheten trots allt gillade styrningen.

Full textAbstract:
"The use of cameras and computer vision algorithms to provide state estimation for robotic systems has become increasingly popular, particularly for small mobile robots and unmanned aerial vehicles (UAVs). These algorithms extract information from the camera images and perform simultaneous localization and mapping (SLAM) to provide state estimation for path planning, obstacle avoidance, or 3D reconstruction of the environment. High resolution cameras have become inexpensive and are a lightweight and smaller alternative to laser scanners. UAVs often have monocular camera or stereo camera setups since payload and size impose the greatest restrictions on their flight time and maneuverability. This thesis explores ORB-SLAM, a popular Visual SLAM method that is appropriate for UAVs. Visual SLAM is computationally expensive and normally offloaded to computers in research environments. However, large UAVs with greater payload capacity may carry the necessary hardware for performing the algorithms. The inclusion of general-purpose GPUs on many of the newer single board computers allows for the potential of GPU-accelerated computation within a small board profile. For this reason, an NVidia Jetson board containing an NVidia Pascal GPU was used. CUDA, NVidia’s parallel computing platform, was used to accelerate monocular ORB-SLAM, achieving onboard Visual SLAM on a small UAV. Committee members:"

Resumo: A capacidade de sistemas heterogêneos cooperarem é uma necessidade atual que vem se impondo cada vez mais, principalmente pelo rápido desenvolvimento da tecnologia de processamento distribuído, obrigando a busca de soluções mais apropriadas. Nesse contexto, a especificação CORBA (Common Object Request Broker Architecture) apresenta uma arquitetura que permite a interoperabilidade entre aplicações em ambientes distribuídos heterogêneos. Entretanto, pela sua grande flexibilidade nas decisões de implementação, surgem problemas para estender essa interoperabilidade entre dois ORBs desenvolvidos por diferentes tecnologias. Nesta dissertação são discutidos esses problemas e suas respectivas soluções, sendo apresentado um conjunto de operações para suportar o mecanismo de interceptação, estendendo as transparências de acesso e localização, consideradas fundamentais num ambiente distribuído, para além do escopo de um ORB. É proposta, também, uma forma para prover transparência de relocação, estendida para suportar interoperabilidade. Por fim, é descrita uma implementação desses mecanismos utilizando um protótipo aberto de ORB e uma implementação comercial, chamada ORBeline.
Abstract: The ability of heterogeneous systems cooperate to problem's solutions is a real need that has been growing, due to the increasing development of the distributed processing technology. This need is driving the development of more suitable solutions. The CORBA (Common Object Request Broker Architecture) specification presents an architecture, which allows interoperability among heterogeneous distributed environment applications. However, because of the great flexibility offered in implementation decisions, many problems to extend interoperability between two ORBs developed by different technologies arise. This work discusses these problems and their solutions and presents a. set of operations to support an interception mechanism extending access and location transparencies, considered as fundamental for a distributed environment, to work beyond an ORB scope. A scheme to provide relocation transparency, extended to support interoperability is also proposed. Finally, an implementation of these mechanisms over an open ORB's prototype and ORBeline, a commercial product, is described.

Full textAbstract:
An object recognition system called ORB1 is proposed and implemented for use on a mobile robot. ORB utilizes the QUADRIS sensor platform developed at the Centre for Intelligent Machines (CIM) at McGill University, which is composed of two BIRIS2 laser rangefinders. ORB performs a series of sensory and perceptual tasks in conjunction with a mobile robot control architecture called SPOTT. ORB's main task is to sense the mobile robot's surroundings and provide laser range data, in the form of line segments, for SPOTT's map database. In an office environment, ORB also identifies and labels the structural objects (i.e., walls, doors) in this map. While navigating through an office space, the mobile robot may be required to search for certain objects in the area. In these scenarios, ORB is used to recognize the movable objects (i.e., chairs, tables and desks).ORB is able to perform its tasks in a fast and efficient manner by using simple models to represent the structural and movable objects in its database. ORB's recognition procedures only require sparse sets of range scans to identify the aforementioned objects. The structural object models are built from prior knowledge of the office environment. For example, the doorway model would consist of the known doorway widths found on the experimental office floor. ORB has been tested extensively in the CIM environment, but it can also be applied to any office space provided the structural dimensions are known a priori. ORB's models for the movable objects are idealized descriptions with the object's surfaces represented by planes. The physical dimensions of the movable object models are defined by Architectural Standards, as office furniture are built to conform to these standards.

Among a myriad of spider web geometries, the orb web presents a fascinating, exquisite example in architecture and evolution. Its structural component, the silk protein, is an exemplary natural material because its superior properties stem intrinsically from the synergistic cooperativity of hierarchically-organized components, rather than from the particular properties of the building blocks themselves. By bridging together different levels of hierarchy in the web, we elucidate the mechanisms by which structure at each composite level contributes to organization and material phenomena at subsequent levels, demonstrating that the web is a highly adapted system where both material and hierarchical structure across all length-scales is critical for its functional properties. Further, the material hierarchy scheme within the orb web is exploited to address questions of silk evolution. Spider orb webs can be divided into two categories distinguished by the capture silk used in construction: cribellate orb webs composed of pseudoflagelliform silk coated with dry cribellate threads and ecribellate orb webs, composed of viscid flagelliform silk fibers, coated by adhesive glue droplets. Cribellate capture silk is generally stronger but less extensible than viscid capture silk and a body of phylogenic evidence suggests that cribellate capture silk is more closely related to the ancestral form of capture spiral silk. Here, we use a coarse-grained web model to investigate how the mechanical properties of spiral capture silk affect the behavior of the web system, illustrating that more extensible capture spiral silk yields a decrease in the web's energy absorption, suggesting that the function of the capture spiral shifted from prey capture to other structural roles. Additionally, we observe that in webs with more extensible capture silk, the effect of thread strength on web performance is reduced, indicating that thread extensibility is a dominant driving factor in web diversification. In this thesis, we propose a novel model-centered materials-hierarchy based approach to studying evolutionary trends and suggest possible applications for other fields.

Previous issue date: 2013The Araneidae Clerck, 1757 has 3029 species in 168 genera. They are common in nature, weaving orbicular bidimensional webs on trees and bushes and, apparently, have nocturnal habits. Spiders of Eustala Simon, 1895 occur throughout all American continent and it seems to be the most speciose Neotropical Araneidae genus. The genus contains about 90 species, 16 of which have been described from Brazil. The male is characterized by the palpus with only one patellar macroseta; conic, whitish hanging down posteriorly median apophysis and the terminal apophysis is a sclerotinized extension, resting on a transparent, baloon-like, subterminal apophysis. The females are characterized by the epigynum with ringed scape pointed anteriorly. The most common pattern color on the abdomen dorsum is a folium. However, this could vary from specimen to specimen, being more or less pigmented. Although frequently collected, species of this genus are poorly known, at present, there are just a few studies on the genus from South America. Thus this study aims to contribute to the knowledge of the Brazilian species of Eustala, through diagnosis and illustrations of species from Southern Brazil, giving continuity to the work initiated about the genus on Rio Grande do Sul state. In order to carry out this study, Eustala material from several arachnological collections was analyzed. Illustrations were made with the aid of camera lucida coupled to the stereoscopic microscope. The left male palpus was illustrated on mesal and ventral views; the epigynum was illustrated on ventral, posterior and lateral views. In current study Eustala ulecebrosa (Keyserling, 1892), from Rio Grande do Sul and E. mourei Mello-Leitão, 1947, from Paraná are illustrated and redescribed. Eight new species from Southern Brazil are described: E. guarani sp. nov., from Paraná; E. catarina sp. nov., from Santa Catarina and E. ericae sp. nov., E. cidae sp. nov., E. lisei sp. nov., E. cuia sp. nov. and E. farroupilha sp. nov, all based on males and females and E. eldorado sp. nov., based only on males, from Rio Grande do Sul. Eustala albiventer (Keyserling, 1884), E. taquara (Keyserling, 1892), E. minuscula (Keyserling, 1892), E. itapocuensis Strand, 1916, E. photographica Mello-Leitão, 1944, E. levii and E. palmares, Poeta, Marques & Buckup, 2010 present new distribution records from Brazil and E. perfida Mello-Leitão, 1947 has a first record in Uruguay.
A família Araneidae Clerck, 1757 agrega 3029 espécies em 168 gêneros. Aranhas comuns na natureza, tecem teias orbiculares bidimensionais na vegetação arbustiva e arbórea e, aparentemente, têm hábitos noturnos. Eustala Simon, 1895 ocorre em todo o continente Americano e parece ser o gênero Neotropical de Araneidae com maior riqueza de espécies. O gênero contém cerca de 90 espécies, das quais 16 são descritas do Brasil. O macho caracteriza-se pelo palpo com única macrocerda patelar, apófise média cônica e esbranquiçada, voltada posteriormente e pela apófise terminal que é um prolongamento esclerotinizado sobre a apófise subterminal, em forma de balão transparente. As fêmeas se caracterizam pelo epígino com escapo dirigido anteriormente, podendo ser liso ou anelado. O padrão de colorido frequente no dorso do abdômen é o fólio, no entanto, muitos espécimes variam na coloração, podendo ser mais ou menos pigmentados. Apesar de frequentemente colecionadas as espécies desse gênero são pouco conhecidas, visto que são escassos os trabalhos taxonômicos do gênero para a América do Sul. Assim, este estudo visa contribuir para o conhecimento das espécies brasileiras de Eustala, através da diagnose e ilustração das espécies dos estados da região Sul do Brasil, dando continuidade ao trabalho iniciado sobre o gênero no estado do Rio Grande do Sul. Para a execução deste projeto, o material de Eustala depositado nas coleções aracnológicas das regiões Sudeste e Sul do Brasil foram examinados. As ilustrações foram realizadas com o auxílio de câmara-clara acoplada ao microscópio estereoscópio. O palpo esquerdo foi ilustrado nas vistas ventral e mesial e o epígino nas vistas ventral, posterior e lateral. No presente trabalho são redescritas Eustala ulecebrosa (Keyserling, 1892), do Rio Grande do Sul e E. mourei Mello-Leitão, 1947, do Paraná. Oito novas espécies são descritas do Sul do Brasil: E. guarani sp. nov., do Paraná; E. catarina sp. nov., de Santa Catarina e E. ericae sp. nov., E. cidae sp. nov., E. lisei sp. nov., E. cuia sp. nov. e E. farroupilha sp. nov., todas baseadas em machos e fêmeas, e E. eldorado sp. nov., baseada em exemplar macho, do Rio Grande do Sul. As espécies Eustala albiventer (Keyserling, 1884), E. taquara (Keyserling, 1892), E. minuscula (Keyserling, 1892), E. itapocuensis Strand, 1916, E. photographica Mello-Leitão, 1944, E. levii e E. palmares, Poeta, Marques & Buckup, 2010 apresentam novos registros de ocorrência no Brasil e E. perfida Mello-Leitão, 1947, tem primeiro registro para o Uruguai.

Resumo: Este estudo investiga a emergência dos conceitos de "nação" e "povo", no Brasil do século XIX, como um paradigma intelectual que delimitou o pensamento de um grupo de escritores genericamente identificados como "gerações românticas". Mesmo quando separados pela filiação partidária, ou pela participação na proteção oficial, todos esses escritores atribuíam a si mesmos e às suas obras um importante papel na construção de um estado nacional. Este papel, desempenhado através da elaboração de uma literatura nacional, é o que chamamos aqui o fardo dos homens de letras
Abstract: This study investigates the rise and consolidation of the concepts of "nation' and "people", in nineteenth-century Brazil, as an intellectual paradigm which bounded the thought of a group of writers generally identified as "romantic generations". Even when separated by party-lines, or by partaking in the official protection, all those writers attributed to themselves and their works an important role in the building of a national state. This role, played through the making of a nationalliterature, is that we call here the men of letters' burden

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThe feline calicivirus (FCV) and the felid herpesvirus type 1 (FeHV-1) are the main agents of the respiratory tract diseases of felines. Both viruses are distributed worldwide, however its distribution and prevalence in Brazil are not well known. In the present thesis we describe the isolation and one serosurvey of FCV and FeHV-1 in some counties of the Rio Grande do Sul State, Brazil; and the molecular characterization of the capsid protein gene of FCV isolates is also described. In Chapter 1, we describe the epidemiologic survey of FCV and FeHV-1 through investigation of the conjunctival, nasal, oral and oropharyngeal swabs from 302 domestic cats. The viral isolation was performed in Crandell-Reese feline kidney cells and the isolates were submitted to PCR and RT-PCR for confirmation of the presence of the FeHV-1 and FCV, respectively. Fifty five (18.2%) of the 302 cats analyzed were positive for the viral isolation; when tested by PCR, 29 cats (52.7%) were shedding the FCV, 21 (38.2%) shedding FeHV-1, and 5 cats (9.1%) shedding both viruses. In addition, isolates of FCV and FeHV-1 were standardized to be used as control in the PCR and virus neutralization (VN) assays (serological technical used in chapter 3 of the thesis). The SV65/90 (FCV) and the SV534/00 (FeHV-1) isolates were defined as standard viruses for the assays. In Chapter 2, the molecular characterization of 13 FCV isolates is described; ten isolates came from the survey performed in chapter 1, two were deposited in the virology laboratory of the UFSM and one was obtained from a cat with gingivitis-stomatitis syndrome. The ORF2 (open reading frame) region that codifies the major protein of the viral capsid was sequenced, which includes an immunodominant region of the virus. The ORF 2 was analyzed at the nucleotide and amino acid levels and these data was used for phylogenetic studies of the 13 Brazilian isolates of FCV. These isolates were compared to ten reference strains of FCV and to the San Miguel sea lion virus type 1 (SMSV-1) as an outgroup in phylogenetic study. The primers were designed using the complete sequence of FCV-F9. The comparison of the 13 Brazilian isolates with the F9 strain revealed a large molecular diversity among them, concentrated mainly along the linear epitopes of the region. The Chapter 3 describes a serosurvey against FCV and FeHV-1 in serum samples from domestic feline. From the 630 samples tested by the VN assay, 53.6% (338/630) were positive to one or both viruses with a prevalence of 39.2% for neutralizing antibodies against FCV and 30.6% for FeHV-1. The results from the present study demonstrated that the FCV and FeHV-1 are circulating among the feline population examined, and also, the presence of carriers of the viruses among these cats. Besides, the molecular characterization of the FCV evidenced the great genetic variability of the Brazilian isolates when compared to vaccine and reference strains.
O calicivírus felino (feline calicivirus FCV) e o herpesvírus felino tipo 1 (felid herpesvirus type 1 FeHV-1) são os principais agentes das doenças do trato respiratório dos felinos. Ambos os vírus são mundialmente distribuídos, mas no Brasil sua distribuição e prevalência são ainda pouco conhecidas. Na presente tese descrevemos o isolamento e sorologia do FCV e do FeHV-1 em alguns municípios do estado do Rio Grande do Sul (RS), Brasil; e a caracterização molecular do gene da proteína do capsídeo de isolados de FCV. No Capítulo 1, descreve-se o isolamento do FCV e do FeHV-1 por meio da coleta de suabes (conjuntival, nasal, oral e orofaringeano) de 302 gatos domésticos. O material coletado foi inoculado em cultivo celular de origem felina (CRFK) e submetidos a PCR e RT-PCR para confirmação em FeHV-1 e FCV, respectivamente. Dos 302 gatos analisados, 55 (18,2%) foram positivos no isolamento; e quando testados por PCR, 29 dos 55 gatos (52,7%) excretavam o FCV, 21 (38,2%) excretavam o FeHV-1 e 5 gatos (9,1%) apresentavam ambos os vírus. Além dessa descrição, realizou-se a padronização de um isolado de FCV e de FeHV-1, para serem utilizados como controle nas técnicas de PCR e na vírus neutralização [VN] (técnica sorológica utilizada no capítulo 3 da tese). O SV65/90 (FCV) e o SV534/00 (FeHV-1) foram os isolados definidos como vírus-padrão. No Capítulo 2, incluímos o estudo sobre a análise molecular de 13 isolados de FCV; dez isolados foram obtidos a partir do material descrito no capítulo 1, dois estavam armazenados no laboratório de virologia da UFSM e um foi obtido de um gato acometido pela síndrome gengivo-estomatite. A região analisada foi o gene da proteína do capsídeo, codificado pela ORF2 (open reading frame), na qual se localizam as regiões imunodominantes do FCV. A ORF2 foi analisada em nível de nucleotídeos e aminoácidos; e uma análise filogenética dos 13 isolados brasileiros de FCV, incluindo dez cepas de referência e o vírus dos leões marinhos de San Miguel tipo 1 (San Miguel sea lion virus type 1 SMSV-1) como um outgroup, foi também realizada. Os primers foram desenhados com base na sequência completa do genoma da cepa de referência a FCV-F9. Quando os 13 isolados brasileiros de FCV foram comparados a cepa F9, detectou-se grande diversidade molecular nas regiões variáveis do gene e nos epitopos lineares mapeados. O Capítulo 3 contem um estudo sorológico contra FCV e FeHV-1 em amostras de soro de felinos domésticos. Das 630 amostras testadas pela VN, 53,6% (338/630) foram positivas para um ou ambos os vírus; sendo a prevalência de anticorpos neutralizantes contra o FCV de 39,2% e do FeHV-1 de 30,6%. Os resultados aqui apresentados demonstram a circulação do FCV e do FeHV-1 na população de gatos domésticos analisados, assim como, a presença de gatos portadores para ambos os vírus. Além disso, a caracterização molecular do FCV demonstrou a grande variabilidade genética dos isolados brasileiros em comparação às cepas vacinais e às de referência.

Full textAbstract:
Circadian clocks enable coordination of essential biological and metabolic processes in relation to the 24-hour light cycle. However, there are many habitats that are not subject to this light cycle, such as the deep sea, arctic regions, and cave systems. This study analyzes the circadian pattern of isolated populations of a subterranean spider, Meta ovalis from two Tennessee caves and five Indiana caves. Locomotor activity was recorded with TriKinetics LAM50 Locomotor Activity Monitor under a 12-hour light (L), 12-hour dark (D) (LD 12:12) cycle preceding total darkness (DD). Significant differences were found within and among populations found in Tennessee cave systems in average free running period and onset of locomotor activity. Selection, drift, and genetic fixation are explored as the causes of variation in the present study, using M. ovalis as the model organism. All five caves in Indiana show little variation, whereas both Tennessee caves show large interindividual variation.

Full textAbstract:
Circadian clocks are endogenous time keeping mechanisms that are ubiquitous among animals. They enable coordination of many essential biological and metabolic processes in relation to the 24 hour light cycle on earth. However, there are many habitats on earth that are not subject to this light cycle. This study aims to look at the potential genetic drift of the circadian rhythm of a subterranean spider, Meta ovalis, as well as gathering general natural history information on this under-studied spider. This study will fill general gaps in knowledge of this spider and its habitat, highlight the importance of studying organisms within a subterranean environment, and place importance on cave conservation and acquiring knowledge of these specialized, and sensitive species. This study integrates circadian and foraging theory to evaluate species as circadian specialists and generalists based on how narrowly or widely their activity is spread over the 24 h cycle. We suggest that M. ovalis benefits from a generalist strategy, showing small bursts of focused activity widely dispersed across the 24 h cycle, allowing it to capture prey opportunistically whenever it is available. Live spiders were collected from area caves, monitored in an environment controlled for light and temperature, and returned to their cave of origin. The activity of each spider was analyzed for differences in circadian activity among and between populations to determine if there is a significant drift of the circadian strategy between isolated populations of Meta ovalis. We expect to see a different circadian strategy implemented between populations due to drift from the spiders being isolated from other populations.

In distributed systems design, middleware is a key component. Middleware establishes the communication between a client and server in a multi-tiered architecture. One approach to middleware is implementing the OMG's CORBA standard, through the use of ORBs. Three of the more popular commercially available ORBs are Sun's Java 2 ORB, Borland's VisiBroker for Java, and IONA's Orbix 2000 for Java. The purpose of this graduate project was to compare the three ORBs both quantitatively and qualitatively. The project compares the ORBs quantitatively by measuring the performance of each ORB, in terms of response time. The comparison was done qualitatively by looking at the services each ORB provides, the level of ease of implementing a simple, client-server application in each ORBs' syntax, the time taken to develop each application, difficulties encountered, and the stability of each ORB when tested. The results of the project should prove to be useful for distributed systems designers, and for researchers studying middleware products. In addition, each of the applications created for the project can be re-used for any future performance or load testing of the ORBs one might want to conduct.

Full textAbstract:
Les Arts de la Mémoire ont initié, il y a déjà vingt-cinq siècles, un chemin vers l’art total, en associant pour la première fois, lieux et mémoire, espace et temps, image et pensée. Ces arts se pratiquent non seulement comme procédés mnémotechniques, mais se révèlent être aussi de véritables machines à manipuler des fantasmes et des images. Ce que les Arts de la Mémoire nous révèlent du lien entre pensée et image, c’est la fonction privilégiée non seulement du paysage imaginaire et de l’inscription de l’homme dans ce paysage, mais aussi de la déambulation qui permet d’organiser symboliquement, selon la logique d’un parcours, la projection des images fixées sur le support de son architecture virtuelle. J’ai tenté de suivre à la trace l’apparition des images en mouvement, dans les explorations de Simonide, Lulle, Bruno, Leibnitz, Warburg, ou Benjamin. Chemin faisant, l’image s’est mise à penser, le texte s’est mis à voir. J’ai imaginé que le cinéma pouvait être ce Palais de Mémoire Total, cette mémoire mobile et ce voyage immobile, ce passage créé de la vie à la représentation de la vie, cette fluidité des métamorphoses et des travellingsSome 2,500 years ago, the Art of Memory paved the way for a total form of the arts, for the first time combining places (loci) and memory, space and time, image and thought. These arts go well beyond the mere process of mnemotechnics, proving also to be powerful machines that can be used to manipulate phantasms and images. What the Art of Memory has to tell us about the relationship between thought and image concerns the privileged function not just of the imaginary landscape and how man is inscribed on it, but also the process of walking abroad or from place to place (deambulation) whereby the projection of the images set onto the medium of one’s virtual architecture can be organised symbolically, following the logic of the path followed. What I have attempted to do is track down the apparition of images in movement in the explorations of Simonides, Llull, Bruno, Leibnitz, Warburg or Benjamin. Following this path, the image became thought and the text became sight. I imagined that cinema could be that total Memory Palace, that mobile memory and immobile journey, the passage created from life to the representation of life, the fluidity of metamorphosis and travelling

Full textAbstract:
L’infection par le virus de l’hépatite E (HEV) est un problème majeur de santé publiquequi touche plus de 20 millions de personnes et tue environ 70 000 chaque année à travers lemonde. Le HEV est la cause majeure d’hépatite virale aiguë dans le monde. En France, laséroprévalence du HEV est de 22,4% dans la population générale. Ce virus se transmet parvoie féco-orale ou par consommation de viande contaminée mal cuite. Très récemment, nousavons décrit un système de culture cellulaire permettant d’amplifier efficacement le HEV. Cesystème représente un outil unique pour caractériser les différentes étapes du cycle infectieuxdu HEV qui sont très mal connues à ce jour. Dans le cadre de ma thèse, je me suis intéresséplus particulièrement à la protéine de capside ORF2 qui est l’unité structurale des particulesvirales et est donc un acteur central du cycle infectieux du HEV. La protéine ORF2 est uneprotéine de 660 acides aminés (aa) qui possède un peptide signal (PS) et trois sites potentielsde N-glycosylation (N1, N2 et N3). J’ai donc étudié le rôle de la N-glycosylation de cetteprotéine ORF2 dans le cycle infectieux du HEV. Pour atteindre cet objectif, la soucheinfectieuse HEV-p6 génotype 3 a été utilisée pour infecter les cellules de la lignéehépatocytaire PLC3, sous clone de la lignée PLC/PRF/5. Les résultats obtenus ont montré quela protéine ORF2 est N-glycosylée uniquement au niveau des sites N1 et N3 ; le site N2 estdéfavorable à la N-glycosylation. Nos résultats ont montré que la N-glycosylation de laprotéine ORF2 n’est pas importante pour sa stabilité, son oligomérisation, sa reconnaissancepar des anticorps, l’assemblage et l’infectiosité des particules virales. Nous avons aussimontré que la protéine ORF2 est importée dans le noyau des cellules hôtes au cours du cycleinfectieux du HEV de manière indépendante de la N-glycosylation. Nous avons identifié pourla première fois un signal de localisation nucléaire (NLS) fonctionnel en position N-terminalede la protéine ORF2 lui permettant d'interagir probablement avec l’importine alpha1. Demanière surprenante, ce NLS régule non seulement l’import nucléaire de cette protéine virale,mais aussi sa translocation réticulaire. Nous avons également démontré que la protéine ORF2est exportée du noyau des cellules hôtes en interagissant avec l’exportine1 et possède 3signaux d’export nucléaire (NES) en position C-terminale. Ces résultats améliorent laconnaissance du trafic intracellulaire de la protéine ORF2 et pourraient orienter les stratégiesantivirales dirigées contre le HEVHepatitis E virus (HEV) infection is a major public health problem that affects more than20 million people and kills approximately 70,000 worldwide each year. HEV is the leadingcause of acute viral hepatitis in the world. In France, the seroprevalance of HEV is 22.4% inthe general population. This virus is transmitted by fecal-oral route or by consumption ofundercooked contaminated meat. Very recently, we have described an efficient cell culturesystem to amplify HEV. This system represents a unique tool for characterizing the variousstages of the infectious HEV lifecycle that are very poorly understood to date. As part of mythesis, I focused on the ORF2 capsid protein which is the structural unit of viral particles andis therefore a central player in the HEV lifecycle. ORF2 is a 660 amino acids protein thatcontains a signal peptide and three potential N-glycosylation sites (N1, N2 and N3). My workaimed to identify the role of the ORF2 N-glycosylation in the HEV lifecycle. Our resultsrevealed that the ORF2 protein is N-glycosylated on the N1 and N3 sites, whereas the N2 siteis not N-glycosylated. Also, the N-glycosylation has no significant relevance neither for thestability, oligomerization, antibody recognition of the ORF2 protein nor for viral assemblyand viral infectivity. We also revealed that, the ORF2 protein is translocated into the nucleusof infected cells, independently of N-glycosylation. We identified for the first time afunctional nuclear localization signal (NLS) located at the N-terminus of the ORF2 proteinthat interacts probably with the importin alpha1. Surprisingly, this NLS regulates both nuclearimport and endoplasmic reticulum translocation of the ORF2 protein. Finally, wedemonstrated that, the ORF2 protein possesses three nuclear export signals (NES) located atits C-terminus. The ORF2 protein interacts with the exportin1 and is exported from the cellnuclei. This interaction drives the ORF2 protein from the nucleus to the cytoplasm of theinfected cells. Hence, this study led to new insights into the molecular mechanisms of theORF2 protein and could help to the design of novel antiviral strategies against HEV

Full textAbstract:
This thesis investigates the problem of tracking objects for an Augmented Reality (AR) setting. More specifically, the issue of tracking Post-It® notes to be used in a Mobile Augmented Reality (MAR) application using the Oriented FAST and Rotated BRIEF (ORB) keypoint extractor and descriptor, is investigated. This problem explores the relatively new and unexplored territory of tracking specific objects in real-time on mobile devices. Since MAR is becoming more prevalent, this is a field that is likely to be explored in more depth in the future. A solution was implemented in an existing note scanning application. Test sequences, with accompanying ground truth, were created for the applicable scenarios. The test sequences were used to reliably verify and evaluate the implementation with regard to precision, recall, accuracy, and speed. The ground truth was generated in a Mixed-Initiative Computing (MIC) application. The results show that tracking using only ORB is not viable if high precision, recall, or accuracy is needed. While tracking via ORB may not be viable as a standalone solution, the thesis describes methods for using it in a MIC setting, which may be viable.Denna masteruppsats undersöker spårning av objekt för användning i en AR- miljö. Mer specifikt så undersöks spårning av Post-It®-notiser för användning i en MAR applikation med hjälp av ORB. Det här problemet utforskar det relativt nya och outforksade området rörande spårning av specifika objekt i realtid på mobila enheter. Eftersom MAR blir alltmer vanligt förekommande, så kommer det här forskningsområdet troligtvis att utforskas mer ingående i framtiden. En lösning implementeras utöver en existerande applikation for att skanna notiser. Testsekvenser, med ackompanjerande faktisk data skapades för de relevanta scenarierna. Dessa testsekvenser användes för att kunna verifiera och utvärdera implementationen med avseende på precision, återkall, träffsäkerhet och snabbhet. All faktisk data genererades i en MIC-applikation. Resultaten visar att spårning med enbart ORB är inte genomförbart om höga krav på precision, återkall, träffsäkerhet eller snabbhet behövs. Medan spårning via ORB måhända inte är genomförbart i nuläget som en självstående lösning, så har den här mastersuppsatsen beskrivit metoder för att använda ORB i en MIC-applikation. Något som faktiskt kan vara genomförbart.

Full textAbstract:
The evolution of technology has led the research into new emerging wearable devices such as the Smart Glasses. This technology provides with new visualization techniques. Augmented Reality is an advanced technology that could significantly ease the execution of much complex operations. Augmented Reality is a combination of both Virtual and Actual Reality, making accessible to the user new tools to safeguard in the transfer of knowledge in several environments and for several processes.
This thesis explores the development of an android based image recognition application. The feature point detectors and descriptors are used as they can deal great with the correspondence problems. The selection of best image recognition technique on the smart glasses is chosen based on the time taken to retrieve the results and the amount of power consumed in the process. As the smart glasses are equipped with the limited resources, the selected approach should use low computation on it by making the device operations uninterruptable. The effective and efficient method for detection and recognition of the safety signs from images is selected. The ubiquitous SIFT and SURF feature detectors consume more time and are computationally complex and require very high-level hardware components for processing. The binary descriptors are taken into account as they are light weight and can support low power devices in a much effective style. A comparative analysis is being done on the working of binary descriptors like BRIEF, ORB, AKAZE, FREAK, etc., on the smart glasses based on their performance and the requirements. ORB is the most efficient among the binary descriptors and has been more effective for the smart glasses in terms of time measurements and low power consumption.

Full textAbstract:
Aureliano Fernandez-Guerra is known especially among Quevedo’s scholars because he published the first complete edition of Quevedo’s works. Few people know his plays and, for this reason, they have never been studied. These plays were written during his youth, when Fernández-Guerra hadn’t decided anything about his career yet. Therefore, these plays were always very important for him and, for this reason, he continued to correct and to revise them. Among them, the unpublished drama La hija de Cervantes (1840) was considered the most important play.
In this doctoral thesis I have tried to describe this Spanish author, especially focusing on theatre. In the first part I wrote about the life and the literary works, giving particularly importance to his plays that are La peña de los enamorados (1939), La hija de Cervantes (1840), Alonso Cano (1842) and La Ricahembra (1845), this last one written in collaboration with Manuel Tamayo y Baus, another important and famous playwright.
In the second part I deepened the study of La hija de Cervantes because it is a particular interesting drama: Aureliano Fernández-Guerra chose to represent the author of the Quixote as a character of his drama, especially dramatizing the most mysterious moments of his life, such as the Gaspar de Ezpeleta’s murder, his relationship with his daughter Isabel de Saavedra and his supposed love for a woman, whose existence his unknown. Besides, this drama is interesting because it is partially autobiographic: I found several letters and articles where it is emphasized the similarities between Cervantes’ and Aureliano’s life: both feel misunderstood and not appreciated by other people and both had to renounce a big love.
In the final part I presented the critical edition of La hija de Cervantes based on the last three manuscripts that are today at the Institut de Teatre in Barcelona. A wide philological note shows the transcription criterions.

Full textAbstract:
Many freshwater mussels are imperiled, due to a number of interrelated factors such as habitat alteration, degradation of water quality, and impoundments. The Golden Orb mussel (Quadrula aurea, I. Lea, 1859) is endemic to the state of Texas and is currently a candidate for the endangered species list, as the number of known populations has been declining in recent years. Little is currently known about Q. aurea aside from basic distribution data. This study is focused on evaluating a combination of macro-habitat and micro-habitat variables to determine their influence on the distribution and density of this species. Macro-habitat variables, including dominant land cover, surface geology, and soil erodibility factor, did not have a significant relationship with mussel distributions. The best model of micro-habitat variables that impacts the Q. aurea distributions is comprised of relative substrate stability (RSS) at moderate flows and current velocity at low flows. For all mussel species in this study, current velocity at low flows is the primary variable that influences distribution. Q. aurea are associated with habitats where larger sediment particles (large gravel and cobble) help to stabilize the substrate in areas with higher current velocities. An understanding of the preferred habitats for Q. aurea can be used to help focus conservation efforts and practices.

Previous issue date: 2013-10-08The Catholic Church elected the last decade of the past century for the investment in television as a resource and mean for evangelization, consolidating its tradition in electronic evangelization, started on the radio in the 50 s. Currently, in Brazil, there are four coexisting catholic television stations, which broadcast nationally: Rede Vida, Canção Nova, TV Século XXI and TV Aparecida, besides the local ones maintained by dioceses. The investment in television means that the physical church itself is no longer the exclusive place for the expression of cult. Our object of study is the analysis of the televisual broadcast produced by two catholic television stations: TV Canção Nova and TV Aparecida. The choice of these stations was made due to the definition of two distinct scenarios of Catholicism: the charismatic scenario and the institutional scenario. Two weeks were randomly selected during the research for an accurate analysis of the broadcast. We will take into consideration for the analysis not only the technical characteristics of the audiovisual but, above all, the content aired. We avoided the comparative analysis between the two stations because it would be irrelevant, considering that both are confessional stations of the same creed. We intend to verify if there is any differential between the broadcast produced by these stations and the others, basing on the hypothesis that by absorbing several formats of radiophonic programs and transposing them to television, confessional Catholics prepare its programming plan in formats that have already been established by evangelization and repeat in their broadcast the formats from nonconfessional stations. Our analysis is based on the case study of the mentioned stations and is supported by theories of cultural miscegenation (GRUZINSKI, 2001; PINHEIRO, 2009); of cultural mediation (MARTIN-BARBERO, 2001, 2004); the spectacle society (DEBORD, 2007); the sociology of absences and the emergencies (SANTOS, 2010)
A Igreja Católica elegeu a última década do século passado para o investimento na televisão como recurso e meio para a evangelização, consolidando a sua tradição na evangelização eletrônica, iniciada nos 1950 no rádio. Atualmente, no Brasil, coexistem quatro emissoras de televisão católicas, que transmitem sua programação nacionalmente: Rede Vida, Canção Nova, TV Século XXI e TV Aparecida, além de emissoras locais mantidas por dioceses. O investimento em televisão faz com que a Igreja física deixe de ser o local exclusivo para a manifestação do culto. O nosso objeto de estudo é a análise da programação televisual produzida por duas emissoras de TVs católicas: TV Canção Nova e TV Aparecida. A escolha destas emissoras obedeceu à definição de dois cenários distintos de catolicismo: o cenário carismático e o cenário institucional. Selecionamos duas semanas, aleatórias, ao longo da pesquisa, para a análise apurada da programação. Levaremos em consideração para a análise, não só as características técnicas do audiovisual, mas, sobretudo o conteúdo de programação veiculado. Evitamos a análise comparativa entre as emissoras citadas, pois seria irrelevante, tendo em vista que ambas são emissoras confessionais do mesmo credo. Queremos verificar se há algum diferencial entre a programação produzida por essas emissoras e as outras emissoras, partindo da hipótese de que absorvendo vários formatos de programas radiofônicos e transpondo-os para a televisão, emissoras confessionais católicas elaboram sua grade de programação em formatos já consagrados pela evangelização e repetem em seus programas formatos encontrados em emissoras não-confessionais. A nossa análise se baseia no estudo de caso das emissoras citadas e é amparada pelas teorias da mestiçagem cultural (GRUZINSKI, 2001; PINHEIRO, 2009); da mediação cultural (MARTIN-BARBERO, 2001, 2004); e da sociedade do espetáculo (DEBORD, 2007); da sociologia das ausências e das emergências (SANTOS, 2010)

SpIOMM (le spectromètre-imageur de l’observatoire du Mont-Mégantic), installé à l’observatoire du Mont-Mégantic depuis 2004, est un spectromètre-imageur à transformée de Fourier qui reste, à ce jour, le seul instrument au monde en mesure d’échantillonner un champ de 12 minutes d’arc en 1.4 millions de spectres dans les longueurs d’onde du visible. L’installation, en 2010, d’une seconde caméra, qui a ouvert la possibilité d’utiliser les données présentes sur le second port de sortie de l’interféromètre, d’une part, et la réalisation de SITELLE (le spectromètre-imageur pour l’étude en long et en large des raies d’émission), une version améliorée de SpIOMM pour le télescope Canada-France-Hawaï, d’autre part, ont rendu impératif le développement d’un logiciel de réduction capable de combiner les données issues des deux ports de sorties pour en tirer toute l’information disponible. L’essentiel de cette thèse porte sur l’élaboration de ORBS, un logiciel de réduction des données de SpIOMM et SITELLE entièrement automatique et conçu sur un modèle architectural ouvert et évolutif. Une étude de la nébuleuse Wolf-Rayet M1-67, réalisée à partir des données de SpIOMM réduites avec ORBS, qui démontre clairement, et pour la première fois, l’existence de deux régions de matériel fortement enrichi en azote, est également présentée à titre d’application.SpIOMM (spectromètre-imageur de l’observatoire du Mont-Mégantic), attached to the telescope of the Observatoire du Mont-Mégantic, is an imaging Fourier transform spectrometer which is still the only instrument in the world capable of sampling a 12 arc-minute field of view into 1.4 million spectra in the visible band. Since the installation in 2010 of a second camera, which has given the possibility of using the data on the second port of the interferometer, on the one hand, and the development of SITELLE (spectromètre-imageur pour l’étude en long et en large des raies d’émission), an upgraded version of SpIOMM, for the Canada-France-Hawaii Telescope, on the other hand, the design of a data reduction software capable of combining the data of both ports, has become a necessity. The main part of this thesis concerns ORBS, a data reduction software for SpIOMM and SITELLE fully automated and based on an open and upgradable architecture. An application to the study of the Wolf-Rayet nebula M1-67, which, for the first time, clearly demonstrates the existence of two regions made of a material strongly enriched in nitrogen, is also presented.

Full textAbstract:
Many studies have investigated the ecological factors that affect behavior in Micrathena gracilis, a diurnal orb-weaving spider that forages exclusively on flying insects during the day. However, none yet have considered how the temporal distributions of prey and predator occurrences shape their daily behavioral rhythms, especially web construction which involves a heavy energetic investment well in advance of potential nutritional benefit. Recently, other spider species have been found to express significant circadian plasticity, suggesting that circadian clock-controlled rhythms may play a larger role in niche partitioning than once thought. Despite the appearance of significant insect abundance in the evenings, M. gracilis individuals stop foraging, take down their webs, and retreat before they can capitalize on this opportunity. Is the nutritional benefit of this forfeited prey significant compared to what they collect during the day, and if so, what potential cost might justify opting out of this potential gain? To investigate, sticky traps for prey collection and a camera array for recording predator activity were used at a local field site to survey what risks and rewards these spiders face throughout the 24-hour day. Spider activity in a lab environment and web captures in the field were also used to confirm behavioral patterns and nutrient uptake throughout the day. It was found that significant prey biomass is given up shortly after the time that spiders typically retreat, suggesting that the spiders truly forfeit this prey and do not simply retreat due to a gradual decrease in overall prey availability. Spiders reliably cease foraging in the early evening and show agitation throughout the night when not comfortably hidden, suggesting that significant extension of foraging behavior may be harshly punished. However, recorded predation events from the camera array were much rarer than anticipated, and no predation was confirmed in the evening. These results support the notion that these spiders’ circadian rhythms are shaped by factors other than prey availability, but more work is necessary to identify these factors

Several studies have investigated the ecological factors that affect behavior in Micrathena gracilis, a diurnal orb-weaving spider that forages on flying insects during the day. However, none yet have considered how the temporal distributions of prey and predator occurrences shape their daily behavioral rhythms, especially web construction, which involves a heavy energetic investment well in advance of potential nutritional benefit. Recently, several orb-weaving spider species have been shown to exhibit a variety of abnormal rhythms, suggesting that circadian clock-controlled rhythms may play an unexpected role in behavioral evolution. Despite the appearance of significant insect abundance in the evenings, M. gracilis individuals stop foraging, take down their webs, and retreat before they can capitalize on this opportunity. Is the nutritional benefit of this forfeited prey significant compared to what they collect during the day, and if so, what potential cost might justify opting out of this potential gain? To investigate, sticky traps for prey collection and a camera array for recording predator activity were used at a local field site to survey what risks and rewards these spiders face throughout the 24-hour day. Spider activity and web captures in the field were also used to confirm behavioral patterns and capture success throughout the day. It was found that spiders begin foraging when prey becomes available but cease while prey is still abundant. These observations appear to support a theoretical model of behavioral decisions under predation risk. However, recorded predation events were rare, and predation was not confirmed outside of the foraging timeframe. These results support the notion that the circadian rhythm of Micrathena gracilis is shaped by factors other than prey availability, but the theoretical pressure from predation risk requires further investigation.

A tradução dessa narrativa fabulosa inscreve-se no projeto de tradução de utopias literárias, como uma das linhas de pesquisa coordenada pelo professor Dr. Carlos Eduardo Ornelas Berriel, no Departamento de Teoria Literária do Instituto de Estudos da Linguagem da Universidade de Campinas, e foi co-orientada pela professora Dra Marie-Luce Demonet, do departamento de Letras Modernas, área Renascimento, do Centre d'Études Supérieures de la Renaissance, durante os dois anos de permanência na cidade de Tours, França (março de 2010 a março de 2012) e até o encerramento do doutorado. As evidências decorrentes de uma leitura linear dessa obra podem encobrir uma profusão de elementos que se distribuem em uma espiral de interesses de seu autor que vão do exercício da Retórica e defesa do vernáculo a um exercício da "ironia" pelo uso da palavra onde falta a liberdade para a sua expressão. Uma abordagem que desvie da linearidade parece ser uma das condições para se prosseguir nos desvendamentos de Alector. A hipótese de que personagens reais pudessem estar travestidos em personagens de ficção orientou a escolha metodológica: pesquisa bibliográfica e abordagem de diferentes centros de documentação, como os Arquivos da cidade de Bourges, Lyon, Paris, Vanves, Roma e Cidade do Vaticano. Intentou-se estabelecer vínculos entre a morte trágica de Barthélemy Aneau e as suspeitas de infiltração calvinista no Collège de la Trinité, onde Aneau foi "Principal" e justificar Alector como metáfora ou ironia de seu tempo. Essa tese organiza-se em duas partes: a Parte A cumpre oferecer um estudo crítico da cidade imaginária de Orbe. Essa parte constitui-se de três momentos: as análises de aspectos gerais da obra, principalmente o julgamento de Alector e o diálogo dos anciãos; a dimensão utópica da cidade orbitana; e, finalmente, a sua dimensão religiosa e a Parte B compreende o estudo que preparou a tradução e contém dois capítulos: o primeiro procura caracterizar a obra, discute o sentido da narrativa em seu contexto e apresenta seu autor, além de uma apresentação geral dos resultados das pesquisas realizadas nos arquivos; o segundo intenta refletir sobre o processo tradutório de Alector, visando a justificar a tradução filológica como uma das perspectivas possíveis de tratamento do corpus submetido ao trabalho de análise, a explicitar o referencial teórico, bem como as etapas de organização do trabalho de tradução. A conclusão retoma sucintamente a discussão apresentada nessas duas partes e vem seguida da tradução bilíngue de Alector, narrativa fabulosa. Os Anexos apresentam o repertório de documentos consultados nos Arquivos e bibliotecas na França, Itália e Cidade do Vaticano. As buscas nos Arquivos não revelaram nenhuma evidência que pudesse confirmar a hipótese anunciada, mas apontaram pistas para o prosseguimento da pesquisa: lacunas encontradas nos documentos da Nunciatura da França e documento inédito encontrado na Bibliothèque muncipale de Lyon sobre a morte do médico encarregado da "autópsia" do corpo de Barthélemy Aneau. Depois da tradução oferecida pelo médico inglês John Hammond, em 1590, espera-se que "Alector, narrativa fabulosa" possa contribuir a fomentar o interesse pelas utopias literárias produzidas durante o período do Renascimento
Abstract: This thesis presents the Portuguese translation of Alector, histoire fabuleuse by Barthelemy Aneau, published in Lyon in 1560 by Pierre Fradin. The translation of that fabulous story is part of the translation project of literary utopias and one of its research lines, supervised by Professor Carlos Eduardo Ornelas Berriel of the Department of Literary Theory of the Instituto de Estudos da Linguagem of the University of Campinas (São Paulo, Brazil); it was co-directed by Professor Marie-Luce Demonet of the Department of Modern Languages, Renaissance Studies, of the Centre d'Études Supérieures de la Renaissance during a two-year doctorate exchange program in the city of Tours, France (March 2010-March 2012). A linear reading of Alector could hide a variety of elements that are distributed in a spiral of interests by the author, ranging from the exercise of Rhetoric and the defense of the vernacular to a practice of 'irony' by the use of speech where freedom of expression lacks. Therefore, a non-linear approach seemed to be a prerequisite to progress in the research and in the interpretations of that work. The assumption that real people could hide behind the fictional characters guided our methodological choices: a survey of the literature and visits to several documentation centers, such as the archives of the city of Bourges, Lyon, Paris, Vanves, Rome, and the Vatican. We aimed to find a connection between the tragic death of Barthélemy Aneau and the suspected Calvinist infiltration at the Collège de la Trinité managed by Aneau and we wanted to demonstrate that Alector is a metaphor or irony of its time. Our thesis is made up of two parts: Part A contains a critical study of the imaginary town of Orbe and is made up of three sections: first, the analysis of the general aspects of the work, especially Alector's trial and the dialogue of the elder; second, the utopian dimension of the city of Orbe and third, its religious dimension. Part B contains the study that prepared the translation and features two sections: the first one characterizes the work, discusses the meaning of the narrative in its context, and introduces its author; it also contains the general analysis of the results of the research conducted at the archives. The second chapter reflects on the process of translating Alector and was developed to justify the philological translation as one of the possible ways of treating the analyzed corpus, to explain both the theoretical basis and the organizational stages of the translation. The conclusion briefly resumes the discussion presented in these two parts and is followed by the bilingual translation of Alector, histoire fabuleuse. The appendices list the documents we looked up at the archives and libraries in France, Italy, and the Vatican. Our research at the archives did not produce any proof that would confirm our hypothesis, but revealed leads for future research, such as the gaps found in the documents of the Nunciature in France or an unpublished document found at the Municipal Library of Lyon on the death of the physician in charge of the "autopsy" of Barthelemy Aneau's body. After the translation provided by the English doctor John Hammond in 1590, we hope that 'Alector, histoire fabuleuse' may contribute to raise interest in the literary utopias of the Renaissance

Full textAbstract:
Few studies have rigorously assessed the adaptive value of diel rhythms in animals. We laid the groundwork for assessing the adaptive rhythm hypothesis by assaying diel rhythms of foraging and antipredator behavior in the orb-weaving spider Cyclosa turbinata. When confronted with a predator stimulus in experimental arenas, C. turbinata exhibited thanatosis behavior more frequently and for longer durations during the day. However, assays of antipredator response within webs revealed more complex diel patterns of avoidance behaviors and no pattern of avoidance behavior duration. Assays of prey capture behavior found that the likelihood of exhibiting prey capture behavior varied significantly across times of day and test subjects, but only test subject predicted attack latencies. Although C. turbinata foraging aggression changed over the diel cycle, we found no evidence of a trade-off between foraging behavior and predator vigilance. However, overall patterns of vigilance may be masked by diel changes in antipredator strategies.

Full textAbstract:
While the thought of having computers recognize objects in images have been around for a long time it is only in the last 20 years that this has become a reality.One of the first successful recognition algorithms was called SIFT and to this day it is one of the most used. However in recent years new algorithms have beenpublished claiming to outperform SIFT. It is the goal of this report to investigate if SIFT still is the top performer 17 years after its publicationor if the newest generation of algorithms are superior. By creating a new data-set of over 170 test images with categories such as scale, rotation, illumination and general detectiona thorough test has been run comparing four algorithms, SIFT, KAZE, AKAZE and ORB. The result of this study contradicts the claims from the creators of KAZE and show thatSIFT has higher score on all tests. It also showed that AKAZE is at least as accurate as KAZE while being significantly faster. Another result was that whileSIFT, KAZE and AKAZE were relatively evenly matched when comparing single invariances that changed when performing tests that contained multiple variables. Whentesting detection in cluttered environments SIFT proved vastly superior to the other algorithms. This led to the conclusion that if the goal is the best possibledetection in every-day situations SIFT is still the best algorithm.

Medical technologies are increasingly moving into the home-setting, and they need to take potential users' experiences into account doing so. This paper explores how interactive point-of-care medical technologies can support and reassure potential users in their waiting during nighttime. Using Research through Design, it presents Mia & the Orb, an interactive home-based for detecting Urinary Tract Infections (UTI). The interactive test incubator guides the user's breathing and provides warmth, orbiting around moments of waiting during nighttime. Using Participatory Design Fiction to unravel user values and a material directed design approach on the physical prototyping phase, it was found that making medical technologies soft, warm and comforting opens up new opportunities to help during painful and helpless moments of waiting.Medicinsk teknik blir alltmer vanligare i hemmet och de måste ta hänsyn till potentiella användares upplevelser. Denna uppsats utforskar hur interaktiva vårdmedicinska tekniker kan stödja och lugna potentiella användare i deras väntan under natten. Med hjälp av ”Research through Design” presenterar den Mia & the Orb, ett interaktivt hembaserat test för att upptäcka urinvägsinfektioner (UVI). Den interaktiva testinkubatorn guidar användarens andning och ger värme under prövande stunder av väntan under natten. Genom att använda ”Participatory Design Fiction” för att upptäcka användares värderingar och en materialstyrd designmetod under den fysiska prototypfasen, antyder att göra medicinsk teknik mjuk, varm och tröstande öppnar upp nya möjligheter att hjälpa till under smärtsamma och hjälplösa ögonblick.

Full textAbstract:
Spider orb-webs have evolved to intercept prey, absorb and dissipate the kinetic energy from prey impact, and retain prey until a spider can subdue their catch. Orb-web structure and function engages scientists from many disciplines, including engineering, behavior, materials science, ecology, and evolution. This dissertation examines the sticky capture spiral component of an orb-web. This composite material is made of supporting fibers covered in sticky glue droplets. These threads are both adhesive and extensible, and their performance is influenced by ambient conditions. The questions I addressed are framed in an ecological context, although they also add to our understanding of materials science. The results of the first study showed that temperature increased the viscosity of glycoproteins within Argiope aurantia droplets, mediating the effect of daily humidity changes, an important environmental effect on the glue's performance. The second study demonstrates that capture spiral droplets of spiders that build webs in habitats ranging from full sun to shade and nocturnal species (Argiope aurantia, Leucauge venusta, Neoscona crucifera, Verrucosa areenata, Micrathena gracilis) is resistant to degradation after a day's worth of UVB exposure. Conversely, after the equivalent of two days of UVB exposure the glue degrades in webs built by M. gracilis that build webs in the shade and N. crucifera, a nocturnal species. The less harsh UVA has little affect on capture spiral glue function, both for species that build webs in full sun and those that build webs at night. The third study documented web asymmetry in Argiope trifasciata orb-webs and identified differences in droplet characteristics across the webs. These spiders differently allocated resources, with the bottom region of the web having twice the droplet volume as the top, and half the ratio of aqueous to glycoprotein material as the inner droplets. Additionally, during foraging times, the bottom of the web experiences higher humidity than the top, which has the potential to increase droplet toughness in this region. This study expands the understanding of web asymmetry by examining the differences in glue characteristics as an additional level of flexibility for web fine-tuning.Ph. D.

Full textAbstract:
Forensic psychiatric nursing is a specialty at the junction of two well-researched intersecting systems with two different mandates: criminal justice (public protection) and health care (public good). Nurses’ involvement at one of the systems’ points of juncture, review board (RB) hearings, has largely been left unexplored. At RB hearings, a panel of legal and health care professionals determines if persons unfit to stand trial (UST) or not criminally responsible on account of mental disorder (NCRMD) represent significant threats to the safety of the public, and orders conditions aimed at keeping the community safe. The aim of this research project was to explore how psychiatric and public safety discourses construct the identity of persons UST or NCRMD during RB hearings, and nurses’ contribution to such identity construction. Critical ethnography methodology was employed, mobilizing three data sources: interviews with forensic psychiatric nurses, observations of RB hearings, and RB documentary artifacts. A poststructuralist lens was used to discern how RB culture produces truths about persons UST or NCRMD that sustain the hegemony of public safety and psychiatric discourses. The main finding was that the forensic psychiatric structure leverages therapeutic nursing interventions and documentation as evidence of deviancy, so that persons UST or NCRMD can be objectified and produced as dangerous, prior to socially rehabilitating them. Discursive structures sustaining the forensic psychiatric system inscribe nursing care within a disciplinary scheme, rendering it coercive and punitive. Thus, a care-and-custody dichotomy is insufficient to explain the complex processes at play in forensic psychiatry. These findings have implications for research, practice, and education in forensic psychiatric nursing, nursing ethics, and other nursing specialties on the medico-legal borderland.

Full textAbstract:
Sharing locally stored media files like music, videos and pictures has not been user-friendly for a long time now. Nowadays people, when they know where the media is stored, have to use the complicated network shares or external storage solutions like USB sticks, hard drives or even CD/DVDs to share media across different users. When the users do not know where the media is stored, they have to use Internet-based peer- to-peer applications like LimeWire, KaZaa or the Gnutella-network, which requires searching and downloading the media first, before being able to actually make use of it. But what if you do not have an Internet connection, do not want to mess around with external storage solutions nor want to wait while downloading or copying from a (network) device, but still want to make use of the media stored on another computer system? Indeed, nowadays there is not any easy solution that provides a very user-friendly, fast and responsive, flexible and stable solution for this. This problem brought us to our research question: “Is there a very easy solution for sharing or watching media throughout the local network?” After some research we stumbled upon some state-of-the-art technologies, which came very close to what we wanted to achieve, however, still having quite some drawbacks, not suitable as a solution for the problem mentioned above. We decided to innovate and tried to find a solution without any drawbacks while still being very user-friendly. We achieved quite good research results showing that: • Using a client-only network was the most efficient and flexible way to provide a stable network structure; • Java was the best programming language to provide a cross-platform application; • For compatibility with the media sharing itself an object-oriented based indexing storage structure, like db4o, yielded the best flexibility and speed in comparison with SQL or other technologies; • The streaming of the media could be achieved best by making use of Java VLC libraries. The user-friendliness of the demo application that we created was also very good, only a few clicks are sufficient to share your media across the network, no need to bother about user rights and so on. We can conclude that our research can be the base of a very successful innovative media sharing system and strongly believe, with some more adjustments in the future, that it has potential to become a very popular application along the media sharing industry.
