Previous issue date: 2017-04-10 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Os polvos s?o os cefal?podes de maior import?ncia no ambiente bent?nico, pois atuam como predadores generalistas e oportunistas, consumindo uma grande variedade de organismos. Por isso, sua ecologia alimentar j? foi estudada utilizando-se diversas metodologias aplicadas a uma variedade de esp?cies do grupo e em diferentes localidades. Entretanto, ainda n?o h? consenso sobre qual t?cnica seria mais eficaz neste tipo de investiga??o, ou mesmo se o emprego de apenas um m?todo seria suficiente. Desta forma, este trabalho teve por objetivo comparar tr?s m?todos quali-quantitativos distintos (an?lise de restos em tocas, de conte?do digestivo e de is?topos est?veis) para caracteriza??o da dieta de Octopus insularis, polvo mais frequente na costa nordeste do Brasil e em suas ilhas oce?nicas. As ?reas de estudo foram: a ReBio Atol das Rocas, ambiente insular, pr?stino e ?nico no hemisf?rio Sul; e Rio do Fogo, na APA Estadual dos Recifes de Corais, ambiente costeiro, com ocupa??o humana e impacto de pesca. No Atol das Rocas, os tr?s m?todos foram utilizados e mostraram resultados distintos. Embora os restos de presas em tocas e o conte?do digestivo tenham apontado crust?ceos como presas principais, apenas o material encontrado nos est?magos mostrou que peixes e poliquetos ocorriam na dieta em quantidades consider?veis. Ambos mostraram propor??es similares de moluscos na dieta, mas diferiram quanto ao seu tipo (gastr?podes nas tocas e cefal?podes nos est?magos). Os is?topos apontaram moluscos como presas principais e crust?ceos como presas secund?rias e corroboraram os resultados do m?todo de conte?do digestivo, que indicou a contribui??o de peixes e poliquetos. Al?m disso, mostraram que equinodermos tamb?m s?o parte da dieta. Em Rio do Fogo, apenas os restos nas tocas e o conte?do digestivo foram avaliados, de forma que o primeiro apontou bivalves como presas principais e crust?ceos em quantidades m?nimas, e o segundo destacou crust?ceos como os mais consumidos e acompanhados de pequenas quantidades de moluscos (gastr?podes, bivalves e qu?tons), peixes e poliquetos. Em geral, as tocas mostram restos de estruturas r?gidas e pesadas das presas, como conchas e carapa?as, e subestimam aquelas com maiores propor??es de tecidos moles, as quais s?o encontradas nos est?magos. Os is?topos, por sua vez, mostram as presas com maiores taxas de assimila??o e talvez sofram influ?ncia do conte?do energ?tico das mesmas. Al?m disso, fatores abi?ticos (ondas e correntes) e bi?ticos (digest?o r?pida dos polvos e outros animais se alimentando nas tocas) tamb?m podem alterar os resultados. Por fim, sugere-se o uso de ao menos dois m?todos complementares, dependendo do objetivo, esp?cie e ?rea de estudo do trabalho. / Octopuses are the most important cephalopods in the benthic environment, since they act as generalist and opportunistic predators, consuming a wide variety of organisms. Their trophic ecology has already been studied using several methodologies applied to a variety of species in different locations. However, there is no consensus on which technique would be more effective in this type of research, or even if the use of only one method would be sufficient. Therefore, the objective of this study was to compare three different qualitative and quantitative methods (analysis of midden piles, digestive content and stable isotopes) to characterize the diet of Octopus insularis, the most frequent octopus on the northeast coast of Brazil and its oceanic islands. The study areas were: the Biological Reserve of Rocas Atoll, an insular, pristine and unique environment in Southern Hemisphere; and Rio do Fogo, inside the State Marine Protected Area of Coral Reefs, a coastal environment, with human occupation and fishing impact. In Rocas Atoll, the three methods were used and showed different results. Although midden piles and digestive content have pointed crustaceans as the main prey, only the material found in the stomachs showed that fishes and polychaetes occurred in the diet and in considerable amounts. Both showed similar proportions of mollusks in the diet, but differed in the type of such organisms (gastropods in the dens and cephalopods in the stomachs). The isotopes pointed mollusks as main prey and crustaceans as secondary prey, corroborated the contributions of fish and polychaetes exhibited by the digestive content and showed that echinoderms are also part of the diet. In Rio do Fogo, only the dens and the stomach contents were evaluated, so that the first one pointed to bivalves as major prey and crustacean in minimal quantities, and the second highlighted crustaceans as the most consumed prey, accompanied by small amounts of mollusks (gastropods, bivalves and chitons), fishes and polychaetes. In general, midden piles show remains of hard and heavy structures of prey, such as shells and carapaces, and underestimate those with high proportions of soft tissues, which are found in the stomachs. The isotopes, on the other hand, show the prey with higher rates of assimilation and may be influenced by their energy content. In addition, abiotic (waves and currents) and biotics factors (rapid digestion of octopuses and other animals feeding in the dens) may also alter the results. Finally, it is suggested the use of at least two complementary methods, depending on the research goals, the species and area to be studied.

Previous issue date: 2014-12-22 / Esta Dissertação de Mestrado aborda o problema de cooperação entre um robô aéreo
e um terrestre em ambientes externos utilizando técnicas de controle não linear e de
processamento de imagens. A ideia é implementar um sistema que permita ao robô
terrestre navegar por um mapa previamente conhecido, sendo capaz de desviar-se de
obstáculos e de recalcular a sua rota quando o robô aéreo, ou ele mesmo, identificar
uma obstrução no caminho. Para isso, os robôs devem ser capazes de determinar por
qual caminho navegarão, de detectar obstáculos e de trocar informações. A detecção de
obstáculos e a identificação das landmarks pelo robô terrestre são realizadas utilizando,
respectivamente, um sensor laser de varredura e processamento de imagens, enquanto o
robô aéreo realiza essas mesmas atividades usando apenas o processamento de imagens.
A vantagem que se obtém através da cooperação com um Veículo Aéreo Não Tripulado
(VANT) é a otimização do tempo de navegação do robô terrestre ao se processar as
imagens capturadas pelo robô aéreo. Esse processamento permitirá a detecção precoce
de adversidades na rota do veículo terrestre e, também, das landmarks nesta mesma
rota. Foram implementados controladores para navegação ponto a ponto e para desvio
de obstáculos. Também se desenvolveu um método para realizar a correção da odometria
do robô terrestre. Além disso, foi desenvolvido um simulador para o robô móvel e uma
interface de comunicação entre os dois robôs. Por fim, foram realizados testes em ambientes
externos a fim de verificar a eficácia do sistema desenvolvido. Através dos resultados
alcançados pôde-se comprovar o funcionamento do sistema proposto. Os robôs foram
capazes de navegar até o ponto destino e o robô terrestre foi capaz de desviar-se dos
eventuais obstáculos, além de efetuar o recálculo do caminho quando uma obstrução foi
encontrada na rota, tanto pelo robô aéreo quanto por ele próprio.

An investigation of intersections between reanimation practice and queer theory in a moving image workKiteley, Robin J. January 2015 (has links)
This practice-informed research establishes points of intersection between reanimative practices within moving image work and queer theoretical positions. It frames this within autoethnographic understandings of memories pertaining to my adolescent experience of gay acculturation via textual sources. A bricolage methodology deriving from the work of Kincheloe and Berry (2004) is used. Multiple methods of investigation are employed including alternative archive creation, moving image tests and prototypes, processes of reading and re-reading and autoethnographic, reflective and academic writing practices. Analysis and evaluation are informed by selected queer theoretical concepts which correspond to the broad structural phases of reanimation. Research outputs deriving from these processes are i) moving image tests, ii) autoethnographic vignettes, iii) a moving image piece entitled Unbounded and iv) a written thesis. The research aims to build on current understandings of the term “reanimation” (Cholodenko, 1991, 2004, 2007a, 2007b, 2007c, 2009; Skoller, 2013; Wells, 1998; Wells & Hardstaff, 2008), particularly within moving image practices using “found” material, and to articulate these within a queer perspective. A contextual review assesses previous work on reanimation in research, scholarship and queer-related animation. A series of moving image tests establish a relationship between animation, deanimation and reanimation which, I propose, constitutes the reanimative process. I consider this practice-informed understanding in relation to analogous patterns and motifs in queer theoretical literature. Finally, evaluation of the evidence from my practice tests and the terminal piece, Unbounded, corroborate a proposed set of intersections. The conclusion offers a conceptualisation of the process of reanimation in my moving image practice and establishes that the reanimated outcome attests to its reanimated status through the “temporal composite” (Skoller, 2013). I build on work concerning queer forms of evidence (Muñoz, 1996, 2009), alternative archive creation (Cvetkovich, 2003), queer temporality (Freeman, 2010; Rohy, 2009; Stockton, 2009) and futurity (Bansel, 2012; Edelman, 2004; Muñoz, 2009) to demonstrate that this reanimative principle is reflective of contemporary queer concerns with historicity. This practice-informed research contributes to knowledge by extending a modest body of animation literature addressing sexuality (de Beer, 2014, 2015, January 21; Griffin, 1994; Halberstam, 2011; Padva, 2008; Pilling, 2012b; Takahashi, 2014; Wells, 1998; Wood, 2008) through its focus on the formal aspects of reanimation and interconnections with the queer, as opposed to the more frequently addressed issue of queer representation.

The place from which I see : a practice-led investigation into the role of vision in understanding solo performance improvisation as a form of compositionElliott, Hilary January 2013 (has links)
The Place From Which I See is a practice-led investigation into performance improvisation in which I have asked the question: ‘What is the role of vision in understanding solo performance improvisation as a form of composition?’ The research is encompassed and presented in two different, but interwoven, modalities, which function as a total thesis. These are: (1) a written thesis, which is divided into the four main chapters outlined in the Introduction and (2) a sharing of studio-based investigations and performances - included on the accompanying DVD - and a live performance. This sharing of practical work is designed to illuminate how the practice has functioned as a methodology for research and as a means of embodying and making public the research outcomes. Together, it is intended that these different articulations form a clear and useful prism through which the practical and theoretical terrain of the project can be distilled. In this thesis I argue that working pragmatically and creatively with vision within the specificity of the immediate space and situation of performance can function as an efficacious means of understanding solo improvised performance as a form of composition, and the research offers five strategies that collectively function as a template of approaches for generating and shaping improvisational material. The strategies have been developed through instigating a practice/theory feedback loop with the phenomenology and artistic paradigm offered by French philosopher Maurice Merleau-Ponty. I introduce his model of painterly composition as a particular rubric of what I call vision/action responsiveness against which I situate my own compositional approaches. I also outline five of the key ideas that infuse both this rubric and his phenomenology more generally - the significance of the entwining of a ‘questioning’ vision with movement; the chiasm; the visible; the ‘invisible’ and the ‘I can’ - and illuminate the way in which the practice has been developed and refined through a pragmatic interaction with these ideas. The thesis also outlines how these aspects of the phenomenological discourse have been re-framed through this interaction with the practical investigations and I situate my working of Merleau-Ponty’s ideas within the context of other treatments within both dance and theatre. More broadly, I relate this doctorate’s methodological approach and aesthetic concern with vision as a core compositional tool in and for performance to the compositional strategies, aesthetics, methodologies and philosophies of a range of other practitioners, locating the research within the wider field of improvisational performance. As an outcome, this research offers the template of strategies, layered with my particular re-framings of Merleau-Ponty’s phenomenology, as an original contribution to the practice and discourse of solo performance improvisation.

'F- f- felt it' : breathing feminist, queer and clown thinking into the practice and study of Sarah Kane's Cleansed and BlastedKane, Nina R. January 2013 (has links)
This thesis uses studio practice, scholarly research, close reading of text, performance observation and conversation with practitioners to establish diverse readings of Sarah Kane’s Cleansed. It includes original material from the 2012 productions of Cleansed in Japan (Kamome-za Fringe Theatre), and in Ireland (Bare Cheek Theatre). It notes practice on Cleansed in gallery spaces (Cast-Off Drama, UK). It offers a dramaturgical approach to workshopping the play from a feminist and queer position, informed by theories of gender and transgender, and the marginalised, loving and delinquent practice of clowning. The research discusses principles of breath, voice and sexuate difference drawing primarily on the philosophies of Luce Irigaray, on the voice practice of Cicely Berry and the clown teaching of Sue Morrison. The work challenges the ‘in-yer-face’ theatre discourse on Kane arguing that it represents a McDonaldization of its subject matter, and an insidious trivialisation of her texts. It offers new thinking on the opening night of Blasted (1995), suggesting that the ‘furore’ was fuelled by collective male hysteria and superstition; its roots centred in mourning. Analysing Cleansed in relation to Edward Bond’s Saved and Lear, it explores tropes of ghosts, stitching and the silent scream, and argues that Kane militates for gynocentric time and becoming. It analyses the symbol of the perimeter fence as a feature of 1980s Britain, noting the strength of binary associations configured in it with reference to both English football hooliganism (male) and the Greenham Common Women’s Peace Camp (female). It argues that Kane sets up heteronormative binaries in Cleansed to debate and contest them. A key conclusion of the thesis is that Cleansed politically addresses and dramatises issues of transgender experience presenting accounts of gender violence, mutability, transitioning, the sharp fractures and silences of gender dysphoria, but also, ultimately, queer desire, love and optimism.

Practical proprioception : an examination of a core physiological foundation for physical performance trainingHaughey, Laura January 2013 (has links)
Proprioception is both the means by which people naturally have a pre-reflective awareness of their bodies, and the mechanism by which performers (and others) can develop advanced levels of bodily awareness in the service of physical skill and psychophysical fluency. These two qualities are amongst the most important for contemporary performers, and this thesis demonstrates how an understanding of proprioception and its enhancement provides a strong foundation for performance training. The original contribution to knowledge in this thesis is to cross epistemological boundaries and bring the scientific research, theory and discourse to the field of actor training, where previously this has not been done. This thesis synthesises theories and definitions of proprioception to provide a clear and comprehensive overview, establishes the functions that proprioception performs, maps relationships between proprioception and related terms and concepts, and argues that proprioception provides a comprehensive model for a core physiological foundation for physical performance training. The research questions under investigation are ‘Can proprioception in physical performers be improved and if so, how will increased proprioception be of benefit to the performer?’ Two research studies are carried out to investigate whether proprioception could be improved in physical performers after targeted proprioceptive training. The studies also explore what benefits the performers accrued during the training and how improved proprioception manifested in their levels of performance. The studies show that proprioception can be improved in performers after participating in proprioceptive training, and demonstrate, explore and evidence that this improvement brings an enhancement in physical performance. Methodologically, an approach is proposed to evaluate training practices which is based in a practice led research paradigm. This research is of interest to actors who use their bodies for specialist skilled movement in training and performance and who undertake a physical approach to their work, and particularly pertinent to actor trainers, providing a rationale to inform, support and enhance training methodologies.

基於CWMP與OAuth的智慧家庭服務維運管理架構 / Toward a CWMP and OAuth Compatible Operations Management Architecture for Smart Home Services王依晴, Wang, Yi Ching Unknown Date (has links)
隨著資訊及通訊技術的快速發展,智慧家庭技術日漸成熟,使得人們的家居生活環境更加便利。由於智慧家庭中技術多元,不同廠商所生產的設備互不相通,導致其操作及安裝程序複雜,影響人們的使用意願,使得目前智慧家庭的願景仍不普及。本論文主要為利用CWMP結合OAuth建立出一個功能完整的智慧家庭服務管理架構,同時兼顧服務使用者與服務供應者的需求,整合家庭內部與外部之間的互動,提供遠端購買模組、佈署服務、監控、計費以及自動偵錯與恢復等管理功能,亦加入了授權與認證規範,期望能提供更完善的管理架構,使得每個家庭雖然由不同的服務與設備組成,但皆能透過同一種技術進行管理,以利智慧家庭維運技術的發展。 / With the rapid development of Information and Communications Technology (ICT), smart home technology has become more and more mature. The applications of smart home technology are still not popular because home devices are usually made by different vendors and thus are not compatible. As a result, the management and setup procedures of these smart home products are complicated. This thesis presents the design and implementation of a CWMP and OAuth based operations management architecture that supports remote purchasing of services and components, deployment of services, diagnosis, billing of service usage and autonomic failure detection and recovery of services. The architecture uses OAuth for supporting security functions of users’ private information. It is expected that the proposed architecture can facilitate the practical applications of smart home technology and provide a reference design for designing operations management mechanisms for smart homes.

Etude de l’interaction canaux calciques de type-N / récepteurs couplés aux protéines G et de son impact dans la tolérance aux effets analgésiques de la morphine. / Study of the interactions between N-type channels and G protein coupled receptors and their impact on morphine tolerance.Accart, Sylvain 29 March 2013 (has links)
Bien que la régulation des canaux calciques par les récepteurs couplés aux protéines G soit connue depuis une trentaine d'année, ce n'est que récemment qu'il a été découvert que ce phénomène pouvait passer par une interaction directe entre ces deux partenaires. Les RCPGs sont les senseurs d'un grand nombre de paramètres (des simples photons aux molécules odorantes en passant par des hormones, acides aminés et nucléotides) et ils contrôlent un grand nombre de processus cellulaires en fonction de ces différents stimuli, ce qui en fait une cible thérapeutique majeure. Une de leurs cibles est l'activité des canaux calciques voltage dépendants qui est responsable d'un grand nombre de processus tels que le contrôle du potentiel de membrane, le relargage de neurotransmetteurs, la contraction musculaire ou, bien sûr, le contrôle du taux de calcium intracellulaire qui est lui-même un second messager impliqué dans de nombreuses voies de régulations.Il nous a donc paru intéressant de se pencher plus en avant sur ces interactions et de trouver une méthode nous permettant de cribler ces interactions potentielles avec des RCPG ciblés pouvant intervenir dans une thématique de contrôle de la douleur. Pour cela nous avons développé une stratégie de FRET en temps résolu utilisant les cryptates de terres rares à déactivation lente couplés aux ligands du tag SNAP comme donneurs de fluorescence, les canaux calciques étudiées étant fusionnés avec cet épitope et l'eGFP fusionnée aux RCPGs en tant qu'accepteur. Ce test nous a permis de confirmer l'interaction entre CaV2.2 et ORL1 le récepteur de la nociceptine. Nous avons ensuite cherché à caractériser plus précisément cette interaction et nous avons déterminé quelles en étaient les séquences peptidiques responsables au sein des domaines C-terminaux de ces deux protéines grâce à des expériences de GST-pull down. Nous avons synthétisé un peptide reproduisant la séquence d'interaction d'ORL1 que nous avons couplé à la séquence TAT, le rendant ainsi capable de pénétrer les membranes cellulaires. Lorsque nous ajoutons ce peptide leurre dans les expériences de TR-FRET, l'augmentation de fluorescence observée en présence de CaV2.2-SNAP et ORL1-GFP disparait totalement alors que l'ajout d'un peptide contrôle composé des mêmes acides aminés mais présentés dans le désordre n'a aucun effet. Nous avons ensuite cherché à étudier les effets de ce peptide in vivo lors d'un protocole de tolérance à la morphine étant donné que les souris K.O. pour le gène d'ORL1 sont résistantes à l'apparition de cette tolérance. Cette stratégie de découplage CaV2.2 :: ORL1 abolit complètement le phénomène de tolérance aux effets analgésiques de la morphine par une action au niveau spinal. Ce travail peut conduire à l'utilisation d'une telle approche dans une perspective thérapeutique visant à améliorer l'utilisation de morphiniques lors du traitement des douleurs chroniques. / The regulation of the calcium channels by GPCRs has been known for almost thirty years but the direction interaction between those two proteins is a recent breakthrough. GPCRs are sensors for a great number of parameters (photons, smell molecules, hormones, amino acids, nucleotides…) and they control numerous cellular functions according to those parameters making them a major target for pharmacology. One of the GPCR's targets is the calcium channel activity which is responsible for a great number of cellular processes like control of the membrane potential, neurotransmitters or hormonal secretion, muscular contraction and, of course, control of the intracellular calcium level which is a second messenger of numerous cell-regulation pathways.It appears to us that it would be interesting to study more closely those interactions and find a way to screen the GPCR/calcium channels interactions that may occur in pain regulation. We developed a strategy of time resolved FRET, using rare earth cryptate coupled to the ligand of the SNAP tag which is fused to the calcium channel as fluorescence donor and eGFP fused GRPRs as acceptors. That test confirmed the interaction between CaV2.2 and ORL1, the nociceptin receptor. We characterized more precisely the peptide sequence of the carboxy-terminal domain of the two proteins which is responsible for the interaction using GST-pull down experiments. We synthesized a peptide reproducing the ORL1 interaction sequence coupled to the TAT sequence allowing to go through the cell membranes. When we add this decoy peptide to ours TR-FRET experiments we lose all the increase of fluorescence that we see in presence of CaV2.2-SNAP and ORL1-GFP but the adding of a control peptide made of the same peptides but scrambled didn't affect the experiment. Then we look for the effects of this peptide in vivo, during a morphine tolerance protocol as it was reported that the ORL1 knock-out mice were insensitive to this phenomenon. This strategy of uncoupling CaV2.2 and ORL1 leads to a complete suppression of the tolerance to the analgesic effects of the morphine by an action at the spinal level. This work could lead to a therapeutic use of this approach which could enhance the use of morphinic compounds in treatment of chronics pains.
