Ön Stora Karlsö, belägen ca 15 km väster om Klintehamn, Gotland, har sedan länge varit skyddad för sina höga naturvärden. På ön finns en fyrplats från 1887 vars bebyggelse är statliga byggnadsminnen. Söder om fyrplatsen finns en gammal igenvuxen fyrträdgård vilken utgör föremål för fallstudie i detta arbete. Karlsö Jagt- och Djurskyddsförening AB äger majoriteten av all mark på ön och förvaltar den, samt bedriver besöksverksamhet. De har en önskan om att eventuellt åter kunna bruka mark i fyrträdgården för småskalig odling av köksväxter. Syftet med arbetet är att genom dokumentation, insamlande av kunskap och information om fyrträdgården på Stora Karlsö bidra till att dess kulturhistoriska värden inte går förlorade vid eventuella nyodlingar i trädgården. Syftet är även att öka kunskapen om fyrträdgårdar och dess betydelse och funktion i Sverige i allmänhet, samt att därigenom synliggöra det gröna kulturarvet i äldre tiders trädgårdsodling. Resultaten visar att trädgården, som var i ständig förändring under tiden den brukades, var hierarkiskt uppdelad mellan de anställda vid fyrplatsen och odlingsytan var indelad i inhägnade lotter. Trädgården har både haft en funktion för självförsörjning och kontemplation och både köksväxter och prydnadsväxter har odlats. Idag finns t. ex. syrener, gullregn, bondpioner samt nio olika äldre sorter av narcisser kvar i trädgården. Avläsbara strukturer i marken samt gjutna fundament för staketstolpar visar var tidigare odlingslotter har funnits. Väldisponerade och genomtänkta nyodlingar i trädgården skulle inte skada dess kulturhistoriska värden, utan snarare bidra till förståelsen av platsens historia och vara positivt ur ett bevarandeperspektiv. / The island of Stora Karlsö, located about 15 km west of Klintehamn, Gotland, has long been protected for its high natural values. There’s a lighthouse from 1887 on the island and buildings connected to it are state monuments. South of the lighthouse there’s an overgrown garden from the lighthouse period which is the subject of study in this essay. Karlsö Jagt- och Djurskyddsförening AB owns the majority of all land on the island and manages it, as well as conducting visiting activities. They have the desire to resume small-scale cultivation of vegetables in the lighthouse garden.The aim of this studie is to, through documentation, gathering of knowledge and information about the lighthouse garden at Stora Karlsö, ensure that its cultural and historical values are not lost in the event of any new cultivation in the garden. The aim is also to increase the knowledge about lighthouse gardens and its importance and function in Sweden in general, and thereby make the green heritage in gardeing of elder times more visible. The results show that the garden, which was in constant change while used, was hierarchically divided between the employees at the lighthouse and the cultivation area was divided into fenced allottments. The garden has both had a function of self-sufficiency and contemplation, and both vegetable plants and ornamental plants have been cultivated. Today there are e. g. lilacs, common laburnum, peony and nine different older varieties of narcissus left in the garden. Structures in the field as well as foundations for fence posts show where previous allotments have been located. If carefully implemented, new cultures in the garden would not damage the cultural and historical value of the garden, but rather contribute to the understanding of the history of the site and be positive from a preservation and maintenance perspective.

This dissertation situates literary modernism in the context of a nascent form of globalization. Before it could be fully acknowledged global encroachment was, by virtue of its novelty, repeatedly experienced as a kind of shattering or disintegration. Through an examination of three modernist novels, I argue that a general modernist preoccupation with space both expresses and occludes anxieties over a globe which suddenly seemed to be too small and too undifferentiated. Building upon recent critical work that has begun to historicize modernist understandings of space, I address the as yet under-appreciated ways in which globalism and its discontents informed all of the locales that modernist fictions variously inhabited. For Joseph Conrad, James Joyce, and Virginia Woolf, the responses to global change were as diverse as the spaces through which they were inflected. / I begin by identifying a modernist predilection for spatial metaphors. This rhetorical touchstone has, from New Criticism onward, been so sedimented within critical responses to the era that modernism's interest in global space has itself frequently been diminished. In my readings of Conrad's Heart of Darkness, Joyce's Ulysses, and Woolf's To the Lighthouse, I argue that the signs of globalization are ubiquitous across modernism. As Conrad repeats and contests New Imperialist constructions of Africa as a vanishing space, that continent becomes the stage for his anxieties over a newly diminished globe. For Joyce, Dublin's conflicted status as both provincial capital and colonial metropolis makes that city the perfect site in which to worry over those recent world-wide developments. Finally, I argue that for Woolf, it is the domestic space which serves best to register and resist the ominous signs of global incursion. In conclusion, I suggest that modernism's anticipatory attention to globalization makes the putative break between that earlier era and postmodernity---itself often predicated upon spatial compression---all the more difficult to maintain.

Space and commercial sexual exchanges, understand the "Lighthouse" among other settings, as a place and practiced as a heterotopic space deviation from theorists such as Foucault (2001) and Certeau (1994). I made use of the oral method and from there I interviewed eleven people selected according to age and knowledge of the historical facts of Olivedos linked to the Lighthouse and Joan Black. For reasons of memory discussion embasei me in theoretical as Candau (2011), with their ratings of memory and Montenegro (2007), for discussion of orality. The look of the research was guided, in the first chapter to Joan Black discussion as protagonist Lighthouse, historicizing the term "black" and their representations to understand how the name of Joan began to be accompanied by the term in the sense surname. In the second chapter problematizei the identity configurations Joan Francelino Lima, comprising from Hall (2000, p. 108), that identities are "fragmented and fractured," multiple. Also in this chapter, I presented the Joan Black tactics for meeting sexual partners and their encounter with the Catholic Church. In the third chapter, I analyzed the Lighthouse and its representations to Olivedos as "practiced place," multiple and named according to the configuration assigned by popular. In the fourth chapter, I analyzed the historical plot that led to deactivation of the lighthouse at the expense of the Municipality of urbanization process. So the historiographical operation here is woven from the space for discussion, as well as Joan identities as protagonist Lighthouse and representation of the History of Women in Olivedos-PB. Thus, these and other stories about Joan and the Lighthouse will be found here from what makes the historian and will be representations of Paraiba history / A pesquisa teve como objetivo perscrutar as memórias referentes ao “Farol e a Joana Preta,” em Olivedos - PB, (1940-1970). Espaço de trocas comerciais e sexuais, entendi o “Farol” dentre outras configurações, como um lugar praticado e como um espaço heterotópico do desvio, a partir de teóricos como Foucault (2001) e Certeau (1994). Fiz uso do método da oralidade e a partir daí entrevistei onze pessoas selecionadas de acordo com a idade e o conhecimento dos fatos históricos de Olivedos atrelados ao Farol e a Joana Preta. Para fundamentação da discussão de memória me embasei em teóricos como Candau (2011), com suas classificações da memória e Montenegro (2007), para a discussão de oralidade. O olhar da pesquisa se orientou, no primeiro capítulo para a discussão de Joana Preta enquanto protagonista do Farol, historicizando o termo “preta” e suas representações para compreender de que forma o nome de Joana passou a ser acompanhado do termo no sentido de sobrenome. No segundo capítulo problematizei as configurações identitárias de Joana Francelino de Lima, compreendendo a partir de Hall (2000, p. 108), que as identidades são “fragmentadas e fraturadas,” múltiplas. Ainda nesse capítulo, apresentei as táticas de Joana Preta para encontros com parceiros sexuais e seu encontro com a igreja católica. No terceiro capítulo, analisei o Farol e suas representações para Olivedos como “lugar praticado,” múltiplo e nomeado de acordo com a configuração atribuída pelos populares. No quarto capítulo, analisei as tramas históricas que levaram a desativação do Farol em detrimento do processo de urbanização do Município. Assim a operação historiográfica aqui tecida ocorre a partir da discussão de espaço, bem como das identidades de Joana enquanto protagonista do Farol e representação da História das Mulheres em Olivedos-PB. Dessa forma, essas e outras histórias sobre Joana e o Farol serão aqui encontradas a partir do que fabrica o historiador e serão representações da História da Paraíba.

This thesis presents the development towards a system that can capture and quantify motion for applications in biomechanical and medical fields demanding precision motion tracking using the lighthouse technology. Commercially known as SteamVR tracking, the lighthouse technology is a motion tracking system developed for virtual reality applications that makes use of patterned infrared light sources to highlight trackers (objects embedded with photodiodes) to obtain their pose or spatial position and orientation. Current motion capture systems such as the camera-based motion capture are expensive and not readily available outside of research labs. This thesis provides a case for low-cost motion capture systems. The technology is applied to quantify motion to draw inferences about biomechanics capture and analysis, quantification of gait, and prosthetic alignment. Possible shortcomings for data acquisition using this system for the stated applications have been addressed. The repeatability of the system has been established by determining the standard deviation error for multiple trials based on a motion trajectory using a seven degree-of-freedom robot arm. The accuracy testing for the system is based on cross-validation between the lighthouse technology data and transformations derived using joint angles by developing a forward kinematics model for the robot’s end-effector pose. The underlying principle for motion capture using this system is that multiple trackers placed on limb segments allow to record the position and orientation of the segments in relation to a set global frame. Joint angles between the segments can then be calculated from the recorded positions and orientations of each tracker using inverse kinematics. In this work, inverse kinematics for rigid bodies was based on calculating homogeneous transforms to the individual trackers in the model’s reference frame to find the respective Euler angles as well as using the analytical approach to solve for joint variables in terms of known geometric parameters. This work was carried out on a phantom prosthetic limb. A custom application-specific motion tracker was also developed using a hardware development kit which would be further optimized for subsequent studies involving biomechanics motion capture.

This thesis aimed to assess the feasibility of using an off-the-shelf virtual reality tracking system as a low cost precision pose estimation solution for robotic operations in both indoor and outdoor environments. Such a tracking solution has the potential of assisting critical operations related to planetary exploration missions, parcel handling/delivery, and wildfire detection/early warning systems. The boom of virtual reality experiences has accelerated the development of various low-cost, precision indoor tracking technologies. For the purpose of this thesis we choose to adapt the SteamVR Lighthouse system developed by Valve, which uses photo-diodes on the trackers to detect the rotating IR laser sheets emitted from the anchored base stations, also known as lighthouses. Some previous researches had been completed using the first generation of lighthouses, which has a few limitations on communication from lighthouses to the tracker. A NASA research has cited poor tracking performance under sunlight. We choose to use the second generation lighthouses which has improved the method of communication from lighthouses to the tracker, and we performed various experiments to assess their performance outdoors, including under sunlight. The studies of this thesis have two stages, the first stage focused on a controlled, indoor environment, having an Unmanned Aerial Vehicle (UAS) perform repeatable flight patterns and simultaneously tracked by the Lighthouse and a reference indoor tracking system, which showed that the tracking precision of the lighthouse is comparable to the industrial standard indoor tracking solution. The second stage of the study focused on outdoor experiments with the tracking system, comparing UAS flights between day and night conditions as well as positioning accuracy assessments with a CNC machine under indoor and outdoor conditions. The results showed matching performance between day and night while still comparable to industrial standard indoor tracking solution down to centimeter precision, and matching simulated CNC trajectory down to millimeter precision. There is also some room for improvement in regards to the experimental method and equipment used, as well as improvements on the tracking system itself needed prior to adaptation in real-world applications. / Master of Science / This thesis aimed to assess the feasibility of using an off-the-shelf virtual reality tracking system as a low cost precision pose estimation solution for robotic operations in both indoor and outdoor environments.
