Ingeniera Civil EléctricaEl desierto de Atacama anida abundantes recursos naturales en sus 105.000 km2. Éste contiene las reservas más grandes de cobre y productos no metálicos del mundo, y los niveles mundiales de irradiancia más altos con un promedio anual de 2.500 kWh/m2 de Irradiancia Horizontal Global (GHI), 3.500 kWh/m2 de Irradiancia Directa Normal (DNI) y de 4.000 horas de sol. A pesar de tener muchas ventajas, también presenta desafíos importantes. A modo de ejemplo, se sabe que las dosis anuales de UV-B en el desierto de Atacama son cerca de un 40% más altas que las típicas del norte de África. Esta parte del espectro no genera más electricidad y podría perjudicar los materiales utilizados en los módulos fotovoltaicos (FV), reduciendo su vida útil. Por ende, un módulo vidrio/vidrio (bifacial) especialmente diseñado para nuestro desierto es parte de la I+D+i FV en el programa solar nacional. Para materiales y diseños de módulos FV ya existentes, datos acerca de observaciones sobre su degradación son variables en su nivel de detalle, consistencia, calidad y significancia estadística. Además, la información disponible acerca de fallas típicas de módulos FV instalados en el desierto de Atacama es escasa o inexistente. A partir del contexto señalado, el objetivo principal de esta tesis es diseñar e implementar una herramienta de inspección para recolectar datos (IDCTool, por sus siglas en inglés), con el fin de evaluar módulos FV que operan en condiciones climáticas desérticas y caracterizarlos. La propuesta se basa en el estado-del-arte de prácticas en terreno junto con la definición de un conglomerado de criterios para su uso en soluciones FV de baja escala. Su implementación incluye el desarrollo de una encuesta, equipos y herramientas; y procedimientos para pruebas en terreno y análisis. IDCTool fue usada para una campaña en la región de Arica y Parinacota, la que es representativa de climas desérticos. Los resultados obtenidos fueron analizados de acuerdo con el procedimiento propuesto. La propuesta metodológica de esta tesis se validó mediante la campaña de Arica. Los 15 sitios visitados (comuna de Arica) fueron clasificados en 4 zonas: la costa, el centro de la ciudad, el valle y el desierto. Durante la campaña se inspeccionó 95 módulos FV, de los cuales se encontraron 9 fabricantes distintos. Los módulos operando por más tiempo llevaban 13 años instalados, los más nuevos llevaban 2 años. Todos los módulos inspeccionados estaban compuestos por un vidrio frontal, una lámina polimérica trasera y marco de aluminio. Según los resultados, no se presentaron fallas en cables, conectores ni celdas solares. La falla más típica fue el efecto soiling con 52 casos de soiling ligero y 39 de soiling fuerte. Otras fallas típicas fueron corrosión menor de la puesta a tierra (18 casos) y corrosión del marco (12 casos). En relación a los parámetros eléctricos, la mayor degradación se observó en la potencia nominal con una caída máxima de 39,08% y una caída promedio de 13,19±6,22%. En relación a la diferencia de temperatura de operación de los módulos FV con respecto a la temperatura ambiente, la mayor diferencia fue 24,45°C con un promedio de 11,67°C. Se encontró que la celda más caliente de todo el universo inspeccionado operaba a 99,4°C, mientras que en promedio las celdas más calientes operaban a 64,0°C. Con respecto a las anormalidades térmicas, se encontraron 2 módulos FV con patrón PID y 12 módulos mostraron celdas homogéneamente muy calientes. El trabajo realizado indica que la herramienta desarrollada, incluyendo la metodología para el análisis, entrega datos en formato estándar capaces de caracterizar módulos FV. Los datos analizados fueron estudiados mediante sus tendencias con el uso de herramientas estadísticas. Por ende, fue posible realizar conclusiones y recomendaciones. A pesar de esto, y debido a la falta de módulos inspeccionados, los fenómenos encontrados durante la campaña no pueden ser generalizados. En efecto, nuestro análisis no está validado por evidencia estadística sólida. En este contexto, el desarrollo de una base de datos significativa, mediante el uso de la IDCTool, será el mejor conjunto de datos como punto de partida para comenzar a hacer recomendaciones concluyentes para desarrollos en el ámbito FV.

Murray, Jacqueline Ruth. "A visual analysis of HIV/AIDS antiretroviral therapy print campaign materials found in four Western Cape community clinic environments". Master's thesis, University of Cape Town, 2016. http://hdl.handle.net/11427/23426.
Testo completoAbstract (sommario):
Print media campaign material strongly influences people's perceptions of illness and health and the role and purpose of medication (NSMC, 2010: np). Because adherence is critical to the successful management of the Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS), the introduction of antiretroviral treatment (ART) into the South African health sector presented a major communications challenge, namely how best to communicate awareness and administration of the drugs and how they should be taken. Over the past ten years, the government Department of Health (DoH), the Treatment Action Campaign (TAC), and other prominent nongovernmental HIV/AIDS organizations (NGOs) such as Love Life, Soul City and the Bishop Tutu Foundation have defined a number of different objectives aimed at the promotion of prescription generic antiretroviral drugs (Venter, 2014:3). This has led to an increase in the number of campaigns, each having singular visual representations of HIV/AIDS and users' relationships to antiretroviral drugs. Despite this, stigma and distrust around HIV/AIDS is prominent among the South African public (Rubincam, 2013:13). As a result, there remains a large amount of ambivalence toward the impact of ART on the body and its place within many communities. This has a direct bearing on issues of adherence. For this reason, it is important to study the nature and efficacy of the materials currently being used for social marketing in this context. This qualitative study therefore questions the nature of the current visual language of ART related leaflets and posters found in four Western Cape community clinics and asks whether the content effectively communicates an understanding of antiretroviral therapy, specifically around issues of adherence. In this study, I aim to identify ART adherence social marketing communication strategies used by leading NGOs and the DoH in South Africa. The nature of the visual and textual representations of antiretroviral print media campaign materials found in four Western Cape community clinic environments is established. The purpose of this research is to provide contemporary and useful information on the style, content, and design of social marketing materials in the hope that it will add significant value for further research on ART adherence. This study is a microanalysis focused on quality, not quantity. The investigation is modest. It does not consider a large sample and is intended as a starting point for further research. I hope to identify possible gaps between the combination of messages offered in leaflet and poster print media, and the needs of those infected with the virus, especially at a time when it necessitates they begin ART. The intended impact of this research is to encourage an increased understanding and awareness by government and NGO marketing departments of their campaign material so that it facilitates the transition onto treatment in a way that is empowering, informative, empathetic, and responsible.

Testo completoAbstract (sommario):
Education in the Swedish school system should aim to assist pupils in the development of fundamental values. This study investigates to what extent different groups of people are represented within two textbooks for English language teaching (ELT), produced in Sweden and commonly used in Swedish schools and how these representations correlate with the values indicated in the curriculum. Additionally, this study explores if textbooks designed for ELT can be adapted and used as a resource in the Arts classroom for multimodal representation analysis. The study used a multimodal critical discourse analysis with a social semiotic approach to address these questions, looking at the textbooks' textual and visual elements. The result is addressed both quantitatively and qualitatively and showed that, while women were shown in active roles, white men were overrepresented in both the visual and textual representations and people of colour of both genders were underrepresented. The results imply that ELT textbooks have some ways to go in order to meet the representation demands that the curriculum sets and that more research needs to address how to more accurately and frequently represent different groups of people within ELT teaching materials.

Testo completoAbstract (sommario):
Thesis (M. Tech.) - Central University of Technology, Free State, 2009The aim of health communication campaigns and visual communication material (VCM) is to positively influence audience health behaviour and attitude. VCM has been used in this respect effectively as a vehicle to convey information about HIV/AIDS over the past three decades. It has been used to promote health knowledge and awareness in order to reduce the transmission of the virus. The aim of this study was to determine the efficacy of graphic imagery in HIV/AIDS VCM. To realise this aim, the researcher set the following objectives: * To review relevant literature in order to isolate key features and process those that communicators must consider/follow when developing HIV/AIDS VCM; * To determine the comprehension of selected outdoor HIV/AIDS messages, the graphics used in these messages, illustration preferences, and an evaluation of the self-efficacy of selected loveLife outdoor visual messages; and * To propose a model that communicators can use as a guideline when developing VCM. The outcome of the review suggests a compilation of features, design guidelines and variables that may contribute to the effectiveness of VCM. The results of the empirical study indicate that suitable graphic imagery fosters message comprehension, while inappropriate imagery inhibits comprehension, and realistic and appropriate imagery is preferred to abstract and representational imagery. Familiar images can contribute towards improved comprehension of HIV/AIDS messages. These findings also gave birth to the proposed ‘O’ communication model, which is a reflection of the results of the empirical study.

Ayers, Drew R. "Vernacular Posthumanism: Visual Culture and Material Imagination". Digital Archive @ GSU, 2012. http://digitalarchive.gsu.edu/communication_diss/34.
Testo completoAbstract (sommario):
Vernacular Posthumanism: Visual Culture and Material Imagination uses a theory of image vernaculars in order to explore the ways in which contemporary visual culture both reflects on and constructs 21st century cultural attitudes toward the human and the nonhuman. This project argues that visual culture manifests a vernacular posthumanism that expresses a fundamental contradiction: the desire to transcend the human while at the same time reasserting the importance of the flesh and the materiality of lived experience. This contradiction is based in a biodeterminist desire, one that fantasizes about reducing all actants, both human and nonhuman, to functions of code. Within this framework, actants become fundamentally exchangeable, able to be combined, manipulated, and understood as variations of digital code. Visual culture – and its expression of vernacular posthumanism – thus functions as a reflection on contemporary conceptualizations of the human, a rehearsal of the posthuman, and a staging ground for encounters between the human and the nonhuman. Each chapter of this project begins in the field of film studies and then moves out toward a broader analysis of visual culture and nonhumanist theory. This project relies on the theories and methodologies of phenomenology, materialism, posthumanism, object-oriented ontology, actor-network theory, film and media studies, and visual culture studies. Visual objects analyzed include: the films of Stanley Kubrick, David Cronenberg, and Krzysztof Kieślowski; Fast, Cheap & Out of Control (1997); the film 300 (2006); the TV series Planet Earth (2006); DNA portraits, the art of Damien Hirst; Body Worlds; human migration maps; and remote surgical machinery.

Testo completoAbstract (sommario):
Design is all about visuals, or that is what I have found out during this thesis, from the process materials to the outcome our main entry point to any problem is how will we solve it visually so it’s understandable for the general user. This aspect is problematic in itself due to the fact that we, as humans, understand the world and the things around using all our senses continuously, even though we can forget as visuals are so overpowering. There is a huge opportunity area in exploring our other senses and bringing them back to technology, and this can be seen in works in the past like Tangible Interactions [1] or Natural User Interfaces [2]. But in this moment in time, where all these new technologies like VR/AR and IoT are about to enter our lives and change them forever, this topic is more important than ever. We have already seen what happens when we turn humans into mere machines with some fingers as interactive inputs, and barely any senses to process all the information given to us. Now that these technologies are still young and malleable, we can direct the future to where we want it instead of being guided by the technology itself. To do this we need to reimagine the design process, not reinvent the wheel, but add experts which we currently leave behind and I argue are key to unlock these technologies, experts not only of the technological side of things but on the human side too, like physiotherapists and dancers. Add also people who we never think about when we think of VR like visually impaired users, which could make these technologies inclusive since early on, instead of as an afterthought like we usually do. Not only people, but we also need to add new materials to understand how we use our senses and explore ways that we can understand and explore them differently; like bodystorming and improv theatre because when things aren’t visual, how do you sketch it? A sketch turns into a video about movement. The end result provides a wide breadth of examples of the types of innovations that can come out of using these new design materials, and to open new frontiers. From a VR game with no visuals whatsoever to an AR location based story game, to a home sized multimodal operating system containing several different apps controlled through physical movement. The examples open up the space instead of closing into a single solution. This is just the tip of the iceberg, a hope that others will be inspired by it and continue with this journey that has just started, to guide the future into one that is more technological and at the same time more human than ever before. What we know is that VR does not equate Visual Reality.

Doutoramento em Estudos de ArteTem-se assistido nos últimos anos, a importantes descobertas na investigação dos fenómenos luminosos e tecnologias ópticas, permitindo o correspondente avanço científico e tecnológico. Essa evolução teve também consequências no campo da arte, que levaram ao desenvolvimento de novas técnicas e formas de expressão plástica. Esta dissertação explora a óptica e a luz laser, de um ponto de vista mais plástico do que técnico, e sugere um resumo da história da luz nas artes visuais. As possibilidades da óptica e luz laser como meios criativos para a arte, são discutidas, juntamente com os seus desenvolvimentos, a partir dos movimentos de arte existentes, e como a óptica e a luz laser têm sido utilizadas pelos artistas. Assim, nos primeiros capítulos organizei com alguma documentação, um comentário em perspectiva histórica, e é nele que reside a minha concepção e desenvolvimento do projecto, bem como naturalmente, das “peças/objectos” que o materializaram. Este trabalho é essencialmente teórico-prático, pelo que as peças criadas para esta tese, são elementos essenciais a ter em conta. As peças/objectos desenvolvidas são “Objectos específicos de luz”, que se intitulam: “Entre duas imagens”, “Espreitar duas vezes”, “Observador observado”, “Observador como elemento estético”, “Observador cinestésico” e “Observador incorporado”. Estes “objectos específicos de luz”, apresentam-se espacialmente colocados segundo um percurso definido, de forma encadeada entre si, obrigando o observador/fruidor, a explorá-los, segundo uma determinada sequência. Nesta sequência proponho evidenciar uma caminhada da LUZ, desde a sua função servil de “iluminar a observação”, até ao seu protagonismo de principal elemento plástico da obra.
In recent years, one has witnessed significant developments concerning the research of light phenomena and optical technologies, which have made the equivalent advances possible, both scientifically and technologically. Such evolution has brought consequences within the artistic field, leading to the development of new ways and techniques of plastic expression. The present essay explores optics and laser light, under a conceptual perspective rather than a technical one, as well a summary of the history of light within visual arts is suggested. The possibilities of optics and laser light as creative media for art are discussed, along with their evolution, this discussion being held upon both the existing art movements and the way optics and laser light have been used by artists. Thus, I have organised a commentary in historical perspective, along a number of documents, in the early chapters. Upon this commentary can one find the grounds upon which the conception and development of my project are based. Those have also been, of course, the bases for conceiving and developing the “parts/objects” that have materialised the project as backup. This is a theoretical-practical work, so the pieces created are crucial elements. The “parts/objects” developed are “Light specific objects”, their titles being: “Between two images”, “Peeping Twice”, “Viewed viewer”, “Viewer as aesthetic element, “Kinetic viewer” and “Incorporated viewer”. Such “Light specific objects” are arranged and linked in a certain way so as to mark a settled route, through which the viewer/enjoyer is led to explore them according to a definite sequence. My goal throughout this sequence is to emphasise a LIGHT trek, from its servile function of “lighting up viewing” to its starring role as the main plastic element of a work.

This dissertation shows how regular cameras can be used to record and analyze the vibrations of visible objects. Through careful temporal analysis, we relate subtle changes in video to the vibrations of recorded surfaces, and use that information to reason about the physical properties of objects and the forces that drive their motion. We explore several applications of our approach to extracting vibrations from video - using it to recover sound from distant surfaces, estimate the physical properties of visible objects, and even predict how objects will respond to new, previously unseen forces. Our work impacts a variety of fields, ranging from computer vision, to long-distance structural health monitoring and nondestructive testing, surveillance, and even visual effects for film. By imaging the vibrations of objects, we offer cameras as low-cost vibration sensors with dramatically higher spatial resolution than the devices traditionally used in engineering. In doing so, we turn every camera into a powerful tool for vibration analysis, and provide an exciting new way to image the world.

Esse estudo objetiva mostrar a inserção sistemática do cesto do tipo Kaipó na sociedade Krahó. Paralelamente sugere um meio de abordagem dos artefatos através do desenho de observação e da reconstrução técnica. Sugere, ainda, o uso do desenho de observação como meio de comunicação dos processos tecnológicos dos artefatos. A análise dos aspectos visuais e estruturais da coleção de cestos Kaipó do acervo do Museu Paulista forneceu dados etnográficos. São 51 exemplares coletados por Harald Schultz e Vilma Chiara nas aldeias Krahó entre as décadas de 40 a 60. Na atualidade dos Krahó não confeccionam o cesto Kaipó. Assim, alguns dados etnográficos foram relacionados a diversos aspectos sociais e culturais dessa etnia, através da pesquisa de campo e da bibliografia pertinente. Outros dados etnográficos remetem a questões, especialmente os trançados específicos desse tipo de cesto - os enfeites - e a seleção de trançados que adotavam frente a um leque de possibilidades suas conhecidas. O cesto Kaipó expressava com seu trançado em diagonal de buriti um mesmo princípio dual ordenador do mundo Krahó. 106 .O cesto Kaipó explicitava aliança social entre parentes afins adquiridos via a relação marido-esposa. O cesto kaipó guardava os bens particulares de uma esposa - iguarias, miudezas e coco-debabaçu - os quais eram consumidos por outras pessoas, mas tendo a sua proprietária como mediadora. De modo claro, as miudezas e o coco-de-babaçu são matéria-prima para a elaboração do corpo humano; através do corte dos cabelos, da depilação, dos adornos e do ato de colorir a pele a mulher constrói aspectos da pessoa Krahó, sejam outras mulheres, crianças e principalmente homens. Essa característica do cesto permanece em uso: recipientes - latas circulares de folhas de flamdres - de tamanhos aproximadamente iguais aos Kaipó são usados com a mesma finalidade e com o mesmo gestual dos antigos Kaipó.Não informado pelo(a) autor(a).

This work explores the possibilities of robust, noise adaptive and automatic segmentation of driver eye movements into comparable quantities as defined in the ISO 15007 and SAE J2396 standards for in-vehicle visual demand measurements. Driver eye movements have many potential applications, from the detection of driver distraction, drowsiness and mental workload, to the optimization of in-vehicle HMIs. This work focuses on SeeingMachines head and eye-tracking system SleepyHead (or FaceLAB), but is applicable to data from other similar eye-tracking systems. A robust and noise adaptive hybrid algorithm, based on two different change detection protocols and facts about eye-physiology, has been developed. The algorithm has been validated against data, video transcribed according to the ISO/SAE standards. This approach was highly successful, revealing correlations in the region of 0.999 between analysis types i.e. video transcription and the analysis developed in this work. Also, a real-time segmentation algorithm, with a unique initialization fefature, has been developed and validated based on the same approach.
This work enables real-time in-vehicle systems, based on driver eye-movements, to be developed and tested in real driving conditions. Furthermore, it has augmented FaceLAB by providing a tool that can easily be used when analysis of eye movements are of interest e.g. HMI and ergonomics studies, analysis of warnings, driver workload estimation etc.

Testo completoAbstract (sommario):
Three independent studies with human functional magnetic resonance imaging (fMRI) measurements were designed to investigate the neural basis of visual glossiness processing in the human brain. The first study is to localize brain areas preferentially responding to glossy objects defined by specular reflectance. We found activations related to gloss in the posterior fusiform (pFs) and in area V3B/KO. The second study is to investigate how the visual-induced haptic sensation is achieved in our brain. We found that in secondary somatosensory area (S2) was distinguishable between glossy and rough surfaces, suggesting that visual information about object surfaces may be transformed into tactile information in S2. In the third study we investigate how the brain processes surface gloss information conveyed by disparity of specular reflections on stereo mirror objects and compared it with the processing of specular reflectance. We found that both dorsal and ventral areas were involving in this processing. The result implicates that in this region the processing of stereoscopic gloss information has a pattern of activation that is additional to the representation of specular reflectance. Overall, the three studies contribute to our understanding about the neural basis of visual glossiness and material processing in the human brain.

The condition of information overload has become a common problem facing contemporary designers. This has resulted in a critical need for the development of "intelligent decision support" systems. One such system would allow a designer to visualize not only material qualities and behavior characteristics, but provide the means to distill, organize, and select relevant data. Material databases and the enabling power of the internet can only be exploited as "information providers" for designers when such a system is adapted. Material selection has been identified as a means of exploring this type of analysis / assessment strategy because it is a specific activity (within the broader realm of design) that is concerned with complex decision making processes. The decision matrix is defined by multiple disciplines, incomplete and varied information , and an explosion in the production of materials that have dynamic properties. Emphasis must be placed on distilling and presenting critical information in a comprehensive and accessible format.

This study is concerned with the development of a practical and effective form of computer-aided analysis of the visual impact of building development in rural areas. Its contribution is fourfold. Firstly, a conceptual model has been developed for the process of seeing in the context of visual impact analysis. Secondly, a mathematical model for a consistent series of visual descriptors has been devised. Thirdly, a suitable design tool has been devised to make use of visual descriptors in visual impact analysis. Fourthly, visual descriptors have actually been implemented as computer software. The concept of visual impact analysis is defined and placed within the wider context of landscape research. The problems faced by a designer in the context of visual impact analysis are identified and the concept of a 'design tool' is introduced and defined. A number of existing computer software packages, intended or used for visual impact analysis, are reviewed critically. The concept of 'visual descriptors' as measures to be used by designers is introduced and examined critically. A conceptual model is presented for the process of seeing in the context of visual impact analysis. A range of possible measures for use as visual descriptors is presented and developed further into a series of precise definitions. A method of implementing visual descriptors is presented together with formal algorithms for the derivation of eight visual descriptors. A software package incorporating these descriptors is presented and verification and case studies of its use carried out. Visual descriptors, as implemented, are assessed for their effectiveness as a design tool for visual impact analysis.

Many animals, including humans, rely on visual input to guide their behaviour and interact with their environment. The study of the visual system is prevalent in neuroscience, however, given the highly complex nature of the brain, we are yet to understand the full functionality of the system. In this study, we set out to explore different aspects of visual processing in the mouse early visual pathway, and how they compare to those in other mammals. In this thesis, we study two major brain structures in the early visual pathway, the dorsal lateral geniculate nucleus (dLGN) in the thalamus, and the primary visual area (V1 or area 17) in the cortex. We aim to explore 3 different aspects of visual information processing in these areas. Firstly, the functional response characteristics of single neurons in the visual thalamus. Secondly, whether additional communication channels are used in thalamo-cortical interactions in the mouse. And lastly, the correlation of behaviour within neuronal population activity in visual cortex. We use data from two different experimental paradigms. One involves an anaesthetised preparation, recording extracellular potentials from the visual thalamus in isolation, or from the visual thalamus and the primary visual cortex simultaneously. The second involves an awake preparation in which animals were trained on a 'Go'/'NoGo' discrimination task and extracellular potentials were recorded from the primary visual cortex during behaviour. This project combines time-series analysis and information theoretical methods to analyse high dimensional multi-electrode array recordings. In addition to the analysis of experimental data, we also explore the practical and methodological implications of measuring communication through cross-frequency coupling and propose an alternative method to measure this phenomenon.

Face-to-face dialogue is the most natural mode of communication between humans. The combination of human visual perception of expression and perception in changes in intonation provides semantic information that communicates idea, feelings and concepts.

This thesis documents the development of a web-application attacking the problem of visualization of co-authorship networks. The visualization encompasses several views.Each of them shows different aspects of the data which is loaded from Academic Archive Online (DiVa), a library system which holds all publications released in the Linnaeus University. To detect relationships among authors, a new interactive layout for Node-Link Diagrams was developed which shows publications, authors and corresponding organizations (faculties, departments) in a radial manner. This Network-View is connected to another view showing the attributes (year, type) of the publications. In development, particular emphasis was placed on a rich support of user interaction in order to equip the user with a tool that allows graphical and explorative analysis of the underlying data.

Testo completoAbstract (sommario):
Previously published studies, using human and non-human animal samples, suggest that stress impairs memory retrieval. However, most human studies that report these impairing effects explore verbal memory only. The aim of the studies reported in this dissertation was to explore the effects of an acute stressor (Study 1), and of administration of prednisone (Study 2), on retrieval of visual-spatial material (both emotional and neutral), and to compare the findings against three theories that attempt to account for the effects of stress on memory: the inverted-U hypothesis (de Kloet et al., 1999), hot-cool theory (Jacobs & Metcalfe, 1998), and the integrated vertical and horizontal perspective theory (Schwabe et al., 2012). To explore the research question, I aimed to systematically replicate, in humans, the pioneering study of de Quervain et al. (1998). They demonstrated that both stress (in the form of foot-shocks) and glucocorticoid treatment impaired memory retrieval, as demonstrated by water maze performance, in rodents. To replicate their design for use in humans, I needed to make several apparatus substitutions. Hence, before embarking on the major studies that constitute the dissertation, I undertook two pilot/preparation studies. Study A verified that a novel visual and spatial task (a virtual environment (VE) water maze task) was a suitable human analog for the Morris Water Maze. Twenty-four participants learned the location of a target in three different VE rooms. Landmarks in the first room were neutral non-arousing pictures; in the second, pleasant arousing pictures; and in the third, unpleasant arousing pictures. Emotional content of landmarks did not affect place learning, although the women demonstrated better recognition for arousing than neutral landmarks. Study B verified that a novel laboratory-based stressor was a suitable substitute for the foot-shock stressor. This novel stressor combines the Cold Pressor Test with the Trier Social Stress Test (TSST) into a single procedure: the Fear Factor Stress Test (FFST). Ninety participants completed one of three conditions: FFST-Stress, FFST-Control, or TSST. The FFST-Stress induced a more robust and sustained cortisol response than the TSST (without increasing participant discomfort), while the FFST-Control condition did not provoke a cortisol response. Following these validation studies, Study 1 explored the effects of the FFST on memory retrieval for the VE rooms created in Study A. Sixty participants learned the location of an invisible target in the VE rooms and, 24 hours later, after undergoing either the FFST-Stress or -Control conditions, completed a set of navigational, recall, and recognition memory tests. In Study 2, the FFST conditions were substituted by a 25mg prednisone dose and a placebo. Following ingestion of the prednisone/placebo, 60 participants completed the same set of navigational and memory tests. Results revealed that neither acute stress nor prednisone administration impaired visual and spatial memory. However, exposure to the acute stressor appeared to enhance verbal memory in women, and prednisone administration appeared to impair verbal memory in both men and women. Relating the current findings to theory revealed that only the inverted-U hypothesis was capable of accounting for the observed pattern of data with regard to verbal memory. Specifically, congruent with predictions derived from that theory, a combination of low levels of endogenous cortisol due to the time of day when procedures were performed, along with the dose-dependent effects of cortisol, might account for the contrasting verbal memory findings seen across Studies 1 and 2. However, none of the three theories were capable of explaining the absence of stress effects on visual and spatial memory. Findings from Studies 1 and 2 therefore suggest that being exposed to an acute stressor or being administered prednisone might have had varying effects across memory domains, which is consistent with a functional perspective on memory. These findings indicate that further investigation into domain-specific effects of stress on memory might be a rewarding area of inquiry.

Dentre as festas públicas e coletivas, podemos citar o carnaval como uma das mais importantes quanto à sua capacidade de representar simbolicamente a formação social e política da sociedade pernambucana. Atualmente, com a devida importância dada aos estudos sobre cultura material e imaterial, em suas formas de expressão consideradas como tradicionais ou populares e a sua salvaguarda, o presente estudo, tendo como “pano de fundo” o carnaval e o surgimento dos clubes carnavalescos pedestres, realizou uma investigação sobre o estandarte dos clubes e troças do carnaval do Recife e Olinda. Sendo o estandarte o principal elemento simbólico dessas agremiações, no qual se confunde, muitas vezes, o sagrado e o profano e sendo ele também um dos primeiros e mais importantes meios de expressão visual do frevo, o nosso estudo realizou, através da revisão bibliográfica das principais obras de viés histórico antropológico que tratam dessa temática e de pesquisa de campo, a análise de uma amostra representativa de estandartes pertencentes aos acervos dessas agremiações e do Paço do Frevo, além de entrevistas com artífices e carnavalescos. Identificou e classificou os elementos estéticos e simbólicos presentes nesses estandartes, integrando as informações levantadas pela revisão bibliográfica com o conteúdo reunido durante a pesquisa, contribuindo com informações importantes sobre os estandartes carnavalescos, sua origem, evolução e simbologia, e obtendo assim, uma compreensão do objeto de estudo na sua totalidade.
Among the public and collective parties, we can mention the carnival as one of the most important as at all, considering its capacity of symbolic representation in two ways: social construction and Pernambuco’s society politics. Actually with the correct magnitude given to academic studies about expressions of material cultures believed traditionals or popular and your safeguard, the present research, realized an investigation into the “carnival gonfalons” of Recife’s and Olinda’s carnival clubs. Emphazing that the “carnival gonfalon” like the principal symbolic element of these refered clubs, mingling, many times, the sacred and the profane, and considering it is one of the begginig and most important ways of Frevo's visual expression as well. Our study performed by literature review of the major works of anthropological historical bias that address this theme and field research, the analysis of a representative sample of “carnival gonfalons” belonging to the assets of these associations and Frevo’s Palace, as well as interviews with artificers and carnival’s people. Identified and classified the aesthetic and symbolic elements contained in these “carnival gonfalons”, integrating the information gathered by literature review content gathered during the research, contributing important information about the “carnival gonfalons”, its origin, evolution and symbols, and obtaining, an understanding of the subject matter in its entirety.

Abstract: Book: fold and labyrinth material aims to test the making of a book object, through experimentation and artistic procedures (graphics, plastics and digital), in close proximity to the concepts of fold and labyrinth by the poststructuralist philosopher Gilles Deleuze (1991). The inspiration for this proposal was my master dissertation entitled Objects and Affects (2014, IEL-Labjor, Unicamp), in which I tried to give visibility to the research writing process, leaving visible erasures, corrections, sketches, with drawings, ink stains and sewing threads, in dialogue with the Brazilian artist Arthur Bispo do Rosário and the poet Manoel de Barros. With the desire to continue the research, in the doctorate we seek to broaden the web of connections between authors and artists to investigate the thesis itself as a shelter of the various gestures and procedures of making a book object (or an object book). A willingness to compose blades of spaces-times in which the imagetext relations unfold through the labyrinths of the visual poetry of Augusto de Campos, Haroldo de Campos and Julio Plaza, through the writings of Jorge Luis Borges, and the books and installations of Edith Derdyk. A search for handmade-digital surfaces that accumulate the layers of the lost directions, the choices drawn, the scrambled paths, the inspiring references of the process of making-writing a book.

The purpose of this study was to explore printed antennas as an alternative technique for applying hyperthermia treatment. The antenna consisted of a printed ground plane and a thin copper plate. The ground plane was made of silver conductive ink printed on a flexible substrate. The challenge of the printed ground plane was limited conductivity. Multi-layer printing was one of the ways to increase the conductivity of the printed trace. This study examined whether the multiple-layered printings on the ground plane influence the performance of the antenna. The ground plane printed on a flexible substrate was evaluated for its conductivity and capacity to handle the heat energy for the extended time duration at the elevated temperature. This research was conducted in two experimental stages. The first stage of the experiment was designed to test conductivity of the ground plane. Ground planes were printed on a 32.5 mm × 17.0 mm substrate. The thickness and resistance of up to five layers of conductive printing were tested to verify how repeated printing improved the resistance and resistivity. Results showed that the multi-layering technique reduced the resistance of the printed trace, but statistically, the ground plane had no significant improvement in resistance beyond the triple layer printing. With an increase of the thickness, resistivity rather increased after the triple layer printing. The second stage of the experiment was used to assess the performance of the entire antenna. Antennas were fabricated using ground planes with triple and quintuple layers based on resistance and resistivity measurements. The antennas showed an acceptable level of performance in terms of antenna return loss and temperature elevation. The statistical analysis of return loss, power handling capability over the time, and temperature elevation was not significant among the antennas with triple and quintuple layered ground planes. Antennas were able to achieve 42 ˚C within 10 minutes at a 2cm deep location with the return loss of -13.76 dB. Most importantly, experimental results showed that antennas were able to handle 15 watt power without degrading the antenna performance. The antenna showed a successful performance in power handling and reaching the tumor temperature.

By first breaking down visual components and visual structure that are commonly used in image construction, this report will try to predict how a audience chooses to view an image. Through eye-tracking technology using a webcam to track the subjects' eye movement, these visual components validation will be tested. The result is presented as heatmaps; which illustrate the point of attention of the audience. The result is then compared with a hypothesis that was compiled in preparation for the examination. The result of the survey shows that potential off using eye-tracking for analysis, though the technology of using a web camera might not be the most suitable.

Focus in the world today is quality and customer orientation. An organization needs to understand the concept of value from the perspective of a customer in order to keep up with expectations on quality, and the turbulent and global environment of today characterized by rapidly changing conditions. This master thesis project was conducted at ABB in Sweden during spring 2020. It is essential for ABB to have an ongoing focus on improvement to maintain a successful organization and enable a competitive future of quality and innovation. The aim of this project was to identify ways to improve material flow and reduce the amount of non-value-added activities that exist in a particular assembly process today. The objective of the project was to conduct proposals on realistic actions for improvement for implementation. Initially in the project a current state was performed and compiled into a specification of requirements and visualized through overall mapping of the material and communication flow. Two of the requirements were reducing the total lead time and ensure the same, or improved, physical and psychosocial work environment. The result of the current state showed that material is not available when needed, material shelves are not structured, and material flow is not optimal. Analysis methods used for analyzing the current state were material flow charts, value stream mapping and spaghetti diagrams. The outcome of the performed analyzes were then used as the foundation for a compiled list of problem areas. All previous performed work was then summarized, discussed and developed into a list of actions for improvement. This phase was performed by initially generating a great amount of ideas, which were then reviewed and evaluated in consideration of the specification of requirements. In addition to the final list of actions, a mapping of the future state was conducted to support the actions and visualize what a future state could look like if the actions are implemented. Lastly, the final list of actions was complemented with another list – a living document of the actions. This document gives the opportunity on a regular basis to monitor progress and should be regularly reviewed and updated. To ensure a successful implementation of improvement work based on the conducted action list, it is recommended to define and clarify responsibility for each action as well as target date and end date. Furthermore, the list should be continuously modified to ensure implementation. It is as well recommended to acknowledge implemented improvements in parallel with performing actions to maintain motivation. Additionally, participation in implementation and promoting dialogue, transparency and respect are valuable factors reducing the negative effects of the implementation of improvement concepts and contributes to a sustainable development of the improvement work.

My investigation of an ‘African aesthetic style’ in this thesis is informed by the production, display and writings on African cultural objects. I demonstrate contemporary jewellery design to derive from a critical methodology, particularly as it facilitates a renegotiation of the relationship and dialogue between the producer and viewer of contemporary jewellery objects.

Testo completoAbstract (sommario):
Despite the fact that photographs come into being as material objects imprinted with light reflected off the subject in front of the camera, and therefore possess a decidedly physical connection to their referent, the materiality of photographs tends to be overlooked in favour of apprehending them as primarily visual signs independent of their physical support. This practice-led research project under the title Taking Photographs Beyond the Visual: Paper as a Material Signifier in Photographic Indexicality explores the status of photographs as physical traces. In an attempt to find ways in which remote natural locations could be expressed more fully than it is possible by means of purely visual representation, papermaking and image-formation are combined in a single process executed entirely on-site. This working method was developed during the course of the project through artist residencies in Switzerland and a thorough research of traditional papermaking that included visits to numerous European paper mills. The making of each work involves an absurdly laborious and time-consuming process of hiking to an alpine location, making paper on-site from local plants and - using only the inherent light-sensitivity of plant substances - exposing it for many days in a camera built there partly from found natural materials. The resulting photographic objects function as pure indices in the semiotician Charles Sanders Peirce’s understanding of the term – as traces that point to their causes without necessarily revealing anything about the nature of the latter. They are artefacts testifying primarily through their presence, rather than through pictorial representation, to the exposure having taken place. Such process of signification requires the viewer’s active, haptic and imaginative response. The work proposes a way of photographically representing place as elemental - that is, existing outside the human schema of production, consumption and meaning – instead of through such cultural constructs as ‘landscape’ or ‘the scenic’.

Little research has been done on the task of how a person searches for images when presented with a set of images, typically those presented by image search engines. By investigating the properties we might be able to present the images in a different manner to ease the users search for the image he/she is looking for. The work was performed at Chiba University under the supervision of Norimichi Tsumura and Reiner Lenz. I created an experimental platform which first showed a target image and then a 7 × 4 grid in which the users task would be to locate the target image. The experiment data was recorded with a NAC EMR-8B eyetracker that saved the data as both a video and serial data stream. The data was later used to extract certain characteristics for different image sets, like how the eye fixates, and how different image sets affect the scan. The initial place where the user started his/her search was dependent on where the user previously was fixating. It was also more probable that subsequent fixations were placed in a close proximity to the previous fixation. My results also show that the search task was slightly faster when images where placed with a high contrast between neighboring images, i.e. dark images next to bright ones etc.

The current proliferation of connected displays and mobile devices from smart phones and tablets to wall-sized displays presents a number of exciting opportunities for information visualization and visual analytics. When a user employs heterogeneous displays collaboratively to achieve a goal, they form what is known as a display ecology. The display ecology enables multiple displays to function in concert within a broader technological environment to accomplish tasks and goals. However, since information and tasks are scattered and disconnected among separate displays, one of the inherent challenges associated with visual analysis in display ecologies is enabling users to seamlessly coordinate and subsequently connect and integrate information across displays. This research primarily addresses these challenges through the creation of interaction and visualization techniques and systems for display ecologies in order to support sensemaking with visual analysis.
This dissertation explores essential visual analysis activities and design considerations for visual analysis in order to inform the new design of display ecologies for visual analysis. Based on identified design considerations, we then designed and developed two visual analysis systems. First, VisPorter supports intuitive gesture interactions for sharing and integrating information in a display ecology. Second, the Spatially Aware Visual Links (SAViL) presents a cross-display visual link technique capable of guiding the user's attention to relevant information across displays. It also enables the user to visually connect related information over displays in order to facilitate synthesizing information scattered over separate displays and devices. The various aspects associated with the techniques described herein help users to transform and empower the multiple displays in a display ecology for enhanced visual analysis and sensemaking.Ph. D.

In this dissertation we propose four methods for the recognition of human activities. In all four of them, the representation of the activities is based on spatiotemporal features that are automatically detected at areas where there is a significant amount of independent motion, that is, motion that is due to ongoing activities in the scene. We propose the use of spatiotemporal salient points as features throughout this dissertation. The algorithms presented, however, can be used with any kind of features, as long as the latter are well localized and have a well-defined area of support in space and time. We introduce the utilized spatiotemporal salient points in the first method presented in this dissertation. By extending previous work on spatial saliency, we measure the variations in the information content of pixel neighborhoods both in space and time, and detect the points at the locations and scales for which this information content is locally maximized. In this way, an activity is represented as a collection of spatiotemporal salient points. We propose an iterative linear space-time warping technique in order to align the representations in space and time and propose to use Relevance Vector Machines (RVM) in order to classify each example into an action category. In the second method proposed in this dissertation we propose to enhance the acquired representations of the first method. More specifically, we propose to track each detected point in time, and create representations based on sets of trajectories, where each trajectory expresses how the information engulfed by each salient point evolves over time. In order to deal with imperfect localization of the detected points, we augment the observation model of the tracker with background information, acquired using a fully automatic background estimation algorithm. In this way, the tracker favors solutions that contain a large number of foreground pixels. In addition, we perform experiments where the tracked templates are localized on specific parts of the body, like the hands and the head, and we further augment the tracker’s observation model using a human skin color model. Finally, we use a variant of the Longest Common Subsequence algorithm (LCSS) in order to acquire a similarity measure between the resulting trajectory representations, and RVMs for classification. In the third method that we propose, we assume that neighboring salient points follow a similar motion. This is in contrast to the previous method, where each salient point was tracked independently of its neighbors. More specifically, we propose to extract a novel set of visual descriptors that are based on geometrical properties of three-dimensional piece-wise polynomials. The latter are fitted on the spatiotemporal locations of salient points that fall within local spatiotemporal neighborhoods, and are assumed to follow a similar motion. The extracted descriptors are invariant in translation and scaling in space-time. Coupling the neighborhood dimensions to the scale at which the corresponding spatiotemporal salient points are detected ensures the latter. The descriptors that are extracted across the whole dataset are subsequently clustered in order to create a codebook, which is used in order to represent the overall motion of the subjects within small temporal windows.Finally,we use boosting in order to select the most discriminative of these windows for each class, and RVMs for classification. The fourth and last method addresses the joint problem of localization and recognition of human activities depicted in unsegmented image sequences. Its main contribution is the use of an implicit representation of the spatiotemporal shape of the activity, which relies on the spatiotemporal localization of characteristic ensembles of spatiotemporal features. The latter are localized around automatically detected salient points. Evidence for the spatiotemporal localization of the activity is accumulated in a probabilistic spatiotemporal voting scheme. During training, we use boosting in order to create codebooks of characteristic feature ensembles for each class. Subsequently, we construct class-specific spatiotemporal models, which encode where in space and time each codeword ensemble appears in the training set. During testing, each activated codeword ensemble casts probabilistic votes concerning the spatiotemporal localization of the activity, according to the information stored during training. We use a Mean Shift Mode estimation algorithm in order to extract the most probable hypotheses from each resulting voting space. Each hypothesis corresponds to a spatiotemporal volume which potentially engulfs the activity, and is verified by performing action category classification with an RVM classifier.
