Full textAbstract:
The moving installation Visible is composed of parts of the classical painting, wooden slats and canvas. It represents the inner walls 8 anonymous portraits of dead children. They represent cruel and incomprehensible pain that a one can commit. Rotating an object is inspired by children's toys, children's carousel and its symbolism and design solutions to commemorate military mobile tent. Object carousel has an octahedral shape with a roof, levitates in the air space, not touching the ground and without a defined border.

All architecture is the interplay between structure, surface and ornament. Traditionally, ornament adorned structure thereby giving it its meaning. A society with its intellectual foundations resting in faith or the abstract emphasized the ornament over the structure. The growth of Rationalism and the substitution of the empirical for the abstract necessarily caused a reordering of ornament and structure. Enabled by technology, structure subsumed ornament. The new architecture was not designed as per canons, rather, new methods for design developed parallel to the technology which enabled its construction. The new architecture, supported by a load bearing skeletal structure represents a turning point in the history of building. The wall was dissolved and replaced by a skeletal structure. The structural members were not covered, rather, their exposure was a conscious act. They served to articulate the resulting architecture which was markedly spatial and expressive. Architecture was no longer confined by stylistic rules. New architecture reconciling realities of how it IS conceived and constructed finds meaning in and of itself. As a result, the conceiving and building of architecture factors into the architectural process. The reordering of the architectural elements of structure and ornament is indicative of the evolution of the intellectual process. Structure, made visible in architecture graphically represents the · thoughts, values and intents of its builders. Architecture in which structure subsumes ornament, is more reflective of the thoughts values and intents of its builders.

PintoraEsta memoria se construye a partir de una narrativa cronológica. Donde hago hincapié en cómo llegué a la carrera de Licenciatura en Artes Visuales y cómo por medio del aprendizaje adquirido comencé a develar los intereses de mi trabajo visual. Por ello, en el presente escrito, entendido como “memoria”, es importante para mí hacer más descriptivo el rememorar de mi desarrollo desde el inicio. Describir los trabajos que surgieron de forma inconsciente, los cuales más que dotarlos con conceptos, estaban impulsados por el quehacer, seguidos por aquellos que intuían las primeras inquietudes plásticas y de lucidez, para luego finalizar con ejercicios que levantan problemáticas aún más reflexivas en torno al quehacer artístico.

Detta examensarbete syftar till att beskriva de displacerade barnens situation ochde utmaningar de står inför på grund av displacement i Cali, Colombia. Detkommer att göras genom att studera de icke-statliga organisationernas arbete dåstaten på många delar i Colombia och Cali har låg närvaro. Många av dessa barntillhör afro-colombianska och inhemska folkgrupper och därför kommer dennastudie att göras utifrån ett intersektionellt perspektiv inom kategorierna etnicitetoch klass. Colombia har under de senaste åren varit det land med flestinternflyktingar i världen, och trots ett fredsavtal med de största rebellgruppernaär Colombia fortfarande ett land i toppen av den globala statistiken. Landetshistoria präglas av interna konflikter, olaglig arbetskraft och narkotikahandel. Deproblem Colombia står inför under denna pågående fredsprocess är komplexa ochpåverkar främst displacerade barn och deras familjer. Resultatet av denna studievisar att många displacerade barn har lägre levnadsstandard än andra barn.Majoriteten bor i ekonomiskt utsatta områden och tillhör minoritetsbefolkningen,de får sämre utbildning och blir ofta diskriminerade på grund av att de ärcolombianer men med en annan kultur och annat ursprung änmajoritetsbefolkningen i staden. Det finns olika typer av socialt arbete i Cali somarbetar med empowerment för att förhindra detta och för att stärka barnen; delsgenom utbildning och dels genom upprätthållande av kultur i form av musik ochdans. Socialarbetare i Cali arbetar oftast utan stöd av staten och är själva eller harvarit displacerade. Många upplever att displacerade barn ofta ses som en homogengrupp trots dennes heterogenitet.This bachelor thesis seeks to describe the displaced children’s situation and thechallenges they face due to displacement in Cali, Colombia. Many of thesechildren belong to Afro-Colombian and indigenous communities and thereforethis study will be made through an intersectional perspective based on ethnicityand class. Colombia was during recent years the country with the most internallydisplaced people in the world, and today, despite a peace agreement with thebiggest guerrilla groups, it is still a country in the top of the global statistics. Thecountry’s history is characterized by internal conflicts, illegal labor and drugtrafficking and the problems they are facing during this peace progress arecomplex. This is affecting displaced children and their families. The humanitariancrisis in Colombia is unique in many ways and have been creating manychallenges for the government. Therefore, one of the main reasons to study non-governmental, social work is because these organizations fill an important gap inresponse to help, support and empower displaced children in areas around Caliwith little governmental presence. The result of this study shows that manydisplaced children in Cali have a lower standard of living than other children. Themajority live in low-income areas and belong to the minority population, theyreceive lower quality education and are often discriminated for being Colombiansbut with a different culture and other origin than the majority population in thecity. There are various types of social work in Cali that work with empowermentto prevent this and to strengthen the children; through education or by maintainingculture in the form of music and dance. Social workers in Cali usually workwithout the support of the state and are run by people who themselves have beendisplaced. Many of the social workers feel that displaced children often are seenas a homogeneous group despite its heterogeneity.

Dee, Hannah-Mary. "Explaining visible behaviour." Thesis, University of Leeds, 2005. http://etheses.whiterose.ac.uk/1338/.
Full textAbstract:
This thesis presents a novel approach to the problem of behaviour modelling within computer vision. This technique is not based upon statistical measures of typicality, but upon building an understanding of the way people navigate towards a goal. Representing movement through the scene in terms of the known goals and obstacles and interpreting people's behaviour as representative of underlying intentions enables behaviour to be explained in terms of these previously defined goals. A family of related algorithms for performing this goal-directed analysis of behaviour are presented and evaluated, alongside a number of metrics for measuring how well the computed explanation matches the observed behaviour. These measurements can be interpreted as measurements of goal-directedness or intentionality. The system is evaluated using a novel methodology which involves comparing the algorithmic output with the performance of humans engaged in a visual surveillance task. An application of this technique is demonstrated within the visual surveillance domain, providing classification of behaviour patterns as explicable or inexplicable. The advantages of such an approach are multiple: it handles the presence of movable goals (for example, parked cars) with ease, and trajectories which have never before been presented to the system can be classified as explicable. The output of the system (for example �Agent n is heading towards goal m� with an associated score indicating how good this explanation is) are easily interpreted. The systems described in this thesis could also in principle be extended to handle richer varieties of scene, moving obstacles, and more complicated systems of goals.

Hussein, Ahmed Taha. "Visible light communication system." Thesis, University of Leeds, 2016. http://etheses.whiterose.ac.uk/15894/.
Full textAbstract:
Visible light communication (VLC) systems have become promising candidates to complement conventional radio frequency (RF) systems due to the increasingly saturated RF band and the potentially high data rates that can be achieved by VLC systems. Over the last decade, significant research effort has been directed towards the development of VLC systems due to their numerous advantages over RF systems, such as the availability of simple transmitters (light emitting diodes, LEDs) and receivers (silicon photo detectors), better security at the physical layer, improved energy efficiency due to the dual functionally (i.e., illumination and communication) and hundreds of THz of license-free bandwidth. However, there are several challenges facing VLC systems to achieve high data rates (multi gigabits per second). These challenges include the low modulation bandwidth of the LEDs, co-channel interference (CCI), inter symbol interference (ISI) due to multipath propagation and the light unit (i.e., VLC transmitter) should be ‘‘ON’’ all the time to ensure continuous communication. This thesis investigates a number of techniques to overcome these challenges to design a robust high-speed indoor VLC system with full mobility. A RGB laser diode (LD) is proposed for communication as well as illumination. The main goal of using LD is to enable the VLC system to achieve multi-gigabits data rates when employing a simple modulation technique (such as on-off keying (OOK)), thus adding simplicity to the VLC system. A delay adaptation technique (DAT) is proposed to reduce the delay spread and enable the system to operate at higher data rates (10 Gb/s in our case). The thesis proposes employing angle diversity receivers (ADR) and imaging diversity receivers to mitigate the impact of ISI, CCI, reduce the delay spread (increase the channel bandwidth) and increase the signal to noise ratio (SNR) when the VLC system operates at high data rates (5 Gb/s and 10 Gb/s) under the effects of mobility and multipath dispersion. Moreover, the work introduces and designs three new VLC systems, an ADR relay assisted LD-VLC (ADRR-LD), an imaging relay assisted LD-VLC (IMGR-LD) and a select-the-best imaging relay assisted LD-VLC (SBIMGR-LD), which are modelled and their performance is compared at 10 Gb/s in two VLC room sizes (5m × 5m × 3m and 4m × 8m × 3m). As well as modelling in two different room scenarios: an empty room and a realistic environment were considered. The work also introduces and designs a high-speed fully adaptive VLC system that employs beam steering and computer generated holograms (CGHs), which has the ability to achieve 20 Gb/s with full receiver mobility in a realistic indoor environment. Furthermore, a new high-speed fast adaptive VLC system based on a divide-and-conquer methodology is proposed and integrated with the system to reduce the time required to identify the optimum hologram. The new system has the ability to achieve 25 Gb/s in the worst case scenario. This thesis also proposes four new infrared (IR) systems to support VLC systems when the light is totally turned off. In addition, it introduces the concept of a collaborative VLC/IR optical wireless (OW) system and investigates the impact of partial dimming on the VLC system performance. An adaptive rate technique (ART) is proposed to mitigate the impact of light dimming. Finally, an IROW system (cluster distributed with beam steering) is introduced to collaborate with a VLC system to maintain the target data rate in the case of partial dimming.

Full textAbstract:
In this thesis, I examine the life and work of Paul Klee and his struggle against the mechanisation of society which led not only to its industrialisation but also to the formalisation of the arts. I suggest further that Klee considered the mechanisation of society to be accelerated by the Great War. Klee strives to confront this increasingly industrialised world through the development of his art, while also reflecting on the very ability of art to address the industrialisation of the everyday life. I examine Klee’s path in this struggle, beginning with his Diaries and also examine his published text, the Creative Credo, written during the War. In the Creative Credo, Klee spells out his newly found understanding of art. The motto from this text: “Art does not reproduce the visible but makes visible” will guide my exploration of Klee’s artistic motivation. I also consider how the artwork of Klee enables the viewer to pull away from the preoccupations and individual involvement of everyday awareness to contemplate the complex “networks” that lay beneath. Klee’s art is not one-dimensional, instead, by investigating complex networks and associations that lay beneath art and life Klee challenges us to rethink art and life itself.1 Klee’s artwork is still able to speak to the contemporary viewer as it did then because we are still subjected to the same battles.

Full textAbstract:
In this thesis, we show that it is possible to design a battery-free light sensing system that can sense and communicate hand gestures while operating fully on harvested power from indoor light. We present two main innovations that push our system to tens of microwatts of power to enable battery-free operation. First, we introduce a novel visible light sensing system that can track variations in light intensity by using a solar cell as a sensor. Solar cells are unlike photodiodes optimized for energy yield in the visible light region and hence do not require any power hungry active components such as an operational amplifier. Furthermore, solar cells can operate under more diverse light conditions as they are not susceptible to saturation under bright light. Second, we devise two ultra-low power communication mechanisms based on radio frequency backscatter to transmit sensor readings at various resolutions without the need of any energy-expensive computational blocks. We design two battery-free and self-powered hardware prototypes that are based on these two innovations. Our first design utilizes an on-board comparator based circuit to perform a 1-bit digitization of changes in light readings, consuming only sub-microwatt of power for digitization. For our second prototype, we design an analog backscatter mechanism that can map raw sensor readings directly to backscatter transmissions. We demonstrate the feasibility of our designs when sensing significant changes in light intensity caused by shadows from hand gestures, and reconstruct these at a receiving device. Our results demonstrate the ability to sense and communicate various hand gestures at a peak power of 20 microwatts when performing 1-bit digitization, and a mean power of 60 microwatts when performing analog backscatter. Both designs represent orders of magnitude improvement in terms of power consumption over state-of-the-art visible light sensing systems.Battery-free Visible Light Sensing

Previously demonstrated integrated optical phased arrays have primarily been implemented in silicon-based platforms and have therefore been limited to operation at infrared wavelengths, where silicon provides low-loss transmission. Developing integrated optical phased arrays for visible wavelengths would enable the exploration of new applications for this technology, such as autostereoscopic displays and neuronal targeting for optogenetics. The work presented in this thesis involves the development of visible light integrated optical phased array components and systems with a focus on autostereoscopic image projection applications. Practical 3D microdisplay applications will require (1) large-aperture phased array systems for diffraction minimization, (2) integrated phase modulation for implementing dynamically reconfigurable phased array antenna elements, and (3) a phased array system architecture for accurately encoding the light field of virtual objects. Integrated photonic architectures for all three aforementioned goals are investigated in this thesis. With respect to the first goal, a 1x1 mm2 aperture visible light phased array with a near diffraction limited far-field spot size is demonstrated. With respect to the second goal, the design of an integrated phase modulator based on the electro-optic tuning of a nematic liquid crystal waveguide cladding layer is developed and a near-x phase shift is demonstrated in a fabricated device. Finally, an autostereoscopic image projection system comprised of multiple tiled phased arrays configured to project a virtual image with parallax in one dimension within an 8.58° field of view is demonstrated.

Full textAbstract:
In this thesis, I examine human-like language generation from a visual input head-on, exploring how people refer to visible objects in the real world. Using previous work and the studies from this thesis, I propose an algorithm that generates humanlike reference to visible objects. Rather than introduce a general-purpose REG algorithm, as is tradition, I address the sorts of properties that visual domains in particular make available, and the ways that these must be processed in order to be used in a referring expression algorithm. This method uncovers several issues in generating human-like language that have not been thoroughly studied before. I focus on the properties of color, size, shape, and material, and address the issues of algorithm determinism and how speaker variation may be generated; unique identification of objects and whether this is an appropriate goal for generating humanlike reference; atypicality and the role it plays in reference; and multi-featured values for visual attributes. Technical contributions from this thesis include (1) an algorithm for generating size modifiers from features in a visual scene; and (2) a referring expression generation algorithm that generates structures for varied, human-like reference.

Full textAbstract:
L’étonnement a une place privilégiée dans la vie des idées, considéré comme l’émotion à l’origine de toutes formes de spéculations philosophiques, il est l’objet d’étude le plus adéquat pour analyser les problèmes communs du cinéma et de la philosophie : le mouvement (Thalès, Héraclite, Zénon d’Élée), la remise en question du réel (Descartes), l’accès au savoir par les sens (Platon). Par l’incarnation de « personnages conceptuels » (l’idiot, le sceptique, le jeune philosophe), le cinéma offre la possibilité d’accéder à des raisonnements philosophiques de manière empirique. Le cinéma sera ainsi considéré comme un outil pouvant mettre en scène le doute cartésien grâce à une déconstruction progressive du réel. Chaque film étudié matérialisera une étape de cette déconstruction : Three Days of the Condor de Sydney Pollack : la remise en question du réel ; Aguirre, la colère de Dieu de Werner Herzog et Bullitt de Peter Yates : le déni du réel, la filmographie de Buster Keaton (courts et longs-métrages) : la trahison des apparences, les œuvres abstraites de Stan Brakhage : la réduction du réel à un entrelacement de formes et de sensations. Cette thèse proposera une redéfinition des causes et des conditions du surgissement de l’étonnement. En effet, étant principalement lié au nouveau dans les différents traités sur l’émotion étudiés (Descartes, Darwin, Charles Le Brun, William James), le rapport entre étonnement et mémoire nécessitera un développement. Ainsi par l’intermédiaire d’une revalorisation de la mémoire affective dans la perception d’un objet étonnant, cette émotion pourra enfin être prise en compte en fonction du passé du sujet. Les différents types de reconnaissance engagés dans la vision d’un film seront analysés pour comprendre à quel moment ce phénomène passe d’un événement mineur à un événement majeur. Le cinéma pourra de cette manière être employé comme un laboratoire mémoriel. Grâce à une approche anthropologique de la première cause de l'étonnement au cinéma : "les feuilles qui bougent" c’est-à-dire le mouvement, le mythe des images vivantes sera étudié du point de vue de sa persistance à différents moments de l’histoire du cinéma du Napoléon d’Abel Gance à Young Sherlock Holmes de Barry Levinson. Ce premier principe étonnant du dispositif cinématographique donnera lieu à une inversion, 4 l’étonnement suscité par une autre vie des images cette fois insufflée par la suspension ou l’arrêt sur image. Enfin « le phénomène saturé » défini par Jean-Luc Marion comme un étonnement surplombant le champ de vision du spectateur sera divisé en une typologie des différents types de saturation au cinéma (le réel surpris, le montage cubiste, la plénitude du cadre etc.), dans le but de trouver un équivalent visuel de l'évidence (première obsession cartésienne). Le dessein de cette typologie inspirée par Descartes sera de réhabiliser les sens dans la construction du savoirAstonishment has a privileged place in the history of philosophy, considered as the emotion behind all forms of philosophical speculation; it is the most appropriate object of study to analyze the common problems of cinema and Philosophy: movement (Thales, Heraclitus, Zeno of Elea), questioning reality (Descartes), access to knowledge through the senses (Plato). Cinema will thus be considered as a tool able to portray Cartesian doubt through a progressive deconstruction of reality. Each film studied materializes a stage of this deconstruction: Three Days of the Condor by Sydney Pollack: questioning reality Aguirre, the Wrath of God by Werner Herzog and Bullitt by Peter Yates: the denial of reality the filmography of Buster Keaton (short and feature films); the betrayal of appearances the abstract works of Stan Brakhage: the reduction of reality to an interweaving of forms and sensations. Thus, by the incarnation of « conceptual characters » (the idiot, the skeptic, the young philosopher), cinema allows us to empirically access to philosophical reasoning. This development will also involve the redefinition of the causes and conditions of astonishment. Indeed, the relationship between astonishment and memory will necessitate a further investigation into, since it is mainly linked to the new and the extraordinary in the different treatises on emotion studied (Descartes, Darwin, Charles Le Brun, William James). Thus, by means of a revaluation of the affective memory in the perception of an astonishing object, this emotion can finally be considered according to the past of the subject. The different types of recognition involved in filmic vision will be analyzed to understand when this phenomenon moves from being a minor event to a major event. In this way, cinema can be used as a memorial laboratory. Thanks to an anthropological approach to the primary cause of astonishment in the cinema: « the moving leaves » (i.e. movement), the myth of living images, will be studied through its persistence at different moments of cinema history from Abel Gance’s Napoleon to Young Sherlock Holmes by Barry Levinson. The first principle of cinematic astonishment leads us to consider its inversion, the astonishment aroused by another aspect of life of images, one dominated by the suspension or the halting of the image. Finally, the « Saturated Phenomena » (defined by Jean-Luc Marion as an astonishment overlooking the spectator's field of vision) will be divided into a typology of the different 6 types of saturation in the cinema (cubist montage, crowded frames, etc.) in order to find a visual equivalent of the evidence (the first Cartesian obsession) and to reassert the value of the senses in the construction of knowledge

Full textAbstract:
The meaning of term &ldquorepresentation&rdquo
has shifted in both relevancy and definition in the discipline of architecture with the introduction of computational design technologies. The assumption of this study is that the selected mode of representation has the power to affect the process of design and even the production of architecture. At the present time, while the discipline is witnessing a change in its tendencies and terminologies, such as from drawing to 3D modeling, from construction to fabrication, and from geometry to topology, it is crucial to look at the &ldquo
conventions&rdquo
of architectural representation that are identified through &ldquo
projections,&rdquo
and particularly the &ldquo
orthographic set&rdquo
. This study aims to challenge the prejudices against the &ldquo
orthographic set&rdquo
that consider it to be an ineffective or inadequate tool for representation in the contemporary practice of architecture following the emergence of &ldquo
digitization&rdquo
. It is the claim of this thesis that the &ldquo
orthographic set&rdquo
is actually a methodology that is still powerful in the visualization of the &ldquo
rational&rdquo
thinking processes of design, and is still a highly pertinent technique in the representation and production of architecture. With the arrival of computational design technologies to the practice of architecture, the &ldquo
visibility&rdquo
of its representations have started to blur
and considering the dialectics between architectural representation and the architectural object, while Modern Architecture can be assessed as the transformation of the orthographic set into a declaration of a stylistic manifesto, in the digital age the question arises of what makes architecture visible, and whether it is possible to come up with a &ldquo
new&rdquo
definition of style.

Full textAbstract:
Device authentication in ad hoc networks is becoming more and more important. Nowadays, there are many interesting applications which communicate via the short-rang wireless communication channel (such as Bluetooth or WiFi). In the communication, a great deal of sensitive information is required to be transmitted. Therefore, device authentication is significant. In order to build a secure authentication mechanism, protocols are proposed using human control visual channels. However, this method brings many challenges, the main one being the burden placed on humans. Therefore, in this thesis, these protocols are optimized using visible light communication techniques, which significantly reduce the work faced by humans.

Full textAbstract:
Genomic DNA is the template of life - the entity which is characterized by a self-sustaining anatomical development, regulated signaling processes, the ability to reproduce and to respond to stimuli. Through what is classically known as the central dogma, the genome is transcribed into mRNA, which in turn is translated into proteins. The proteins take part in most, if not all, cellular processes, and it is by unraveling these processes that we can begin to understand life and disease-causing mechanisms. In vitro and in vivo assays are two levels at which protein communication may be studied, and which permit manipulation and control over the proteins under investigation. But in order to retrieve a representation of the processes as close to reality as possible, in situ analysis may instead be applied as a complement to the other two levels of study. In situ PLA offers the ability to survey protein activity in tissue samples and primary cell lines, at a single cell level, detecting single targets in their natural unperturbed environment. In this thesis new developments of the in situ PLA are described, along with a new technique offering in situ enzyme-free detection of proximity between biomolecules. The dynamic range of in situ PLA has now been increased by several orders of magnitude to cover analogous ranges of protein expression; the output signals have been modified to offer a greater signal-to-noise ratio and to limit false-positive-rates while also extending the dynamic range further; simultaneous detection of multiple protein complexes is now possible; proximity-HCR is presented as a robust and inexpensive enzyme-free assay for protein complex detection. The thesis also covers descriptions on how the techniques may be simultaneously applied, also together with other techniques, for the multiple data-point acquisition required by the emerging realm of systems biology. A future perspective is presented for how much more information may be simultaneously acquired from tissue samples to describe biomolecular interactions in a new manner. This will allow new types of biomarkers and drugs to be discovered, and a new holistic understanding of life.

This context statement presents a critical examination of my work as a documentary photographer, focusing on the long-term project Nowhere People (2005-2016). It reveals as well the impact statelessness has on individuals and communities around the world. Given the interdisciplinary nature of this topic, the statement will employ methods of auto-ethnography as well as theories of state, human rights, memory and identity in order to illustrate the significance of the visual in articulating the lives of stateless populations. This statement attempts to connect my own experience and journey of working in the field of documentary photography with the growing discussion and debate related to the state, human rights, nationality and the rights of non-citizens. I will demonstrate how this portfolio of public works presents a multidimensional portrait of this issue in a way that contributes to filling in substantial evidence gaps in the context of human rights by making the various elements of this invisible condition, visible. In addition, I will survey photography’s capacity to translate deficiencies inherent within human rights and international law and examine its role in challenging contemporary definitions of citizenship and identity. I will discuss how I have navigated my work and the project Nowhere People through debates related to subjectivity, agency, representation, spectatorship and the interconnectedness between photographer, subject and viewer. I will also detail the pragmatic decisions I have made relating to the authorship and dissemination of the work to various audiences in relation to the tectonic shift in the access to information and use of the image within this shifting paradigm of visual culture.

Full textAbstract:
Visible light communications (VLC) is an emerging technology of optical wireless communications, which has been in the research spotlight recently, thanks to the remarkable development of light emitting diodes. Furthermore, optical camera communications, a timely VLC topic, has earned a great share of researchers'interest in the last few years, given the wide availability of digital cameras. This thesis proposes to merge two separate technologies: image processing and VLC, to create a camera-based VLC system. Moreover, the work presented in this thesis describes a short-range mobile-to-mobile communication link, where the transmitter and the receiver are the smartphone’s screen and camera, respectively. In addition, the data is encoded into images and subsequently beamed out of the transmitter's screen, and the receiver's camera captures consecutive frames containing the transmitter's screen to extract the data. The proposed system offers inherent advantages in terms of portability and simplicity of implementation as it uses available screens and smartphone cameras. Additionally, the system is software-based and does not require any hardware modifications on the devices, thus making a high potential for millions of consumers. The system proposed in this thesis is designed for mobile users. Therefore, high performance in dynamic environments is required. Moreover, combining image processing and VLC for smartphone to smartphone VLC is an innovative topic and very few works reported similar communication links. As such, it is imperative to investigate the impact of computer vision challenges on the system's performance, such as the detection of the transmitter by the receiver's camera, in dynamic conditions. Consequently, this work focuses on the development of an effective algorithm to capture frames containing the transmitter as well as other objects in the background, detect the transmitter contained in the received frames, and then finally extract the originally transmitted information. The end-to-end system is fully implemented on a mobile platform and a range of experiments are carried out in order to evaluate the system's performance. It is proved that the system is able to achieve very high success rate that reaches 98% data recovery of transmitted images under test conditions, demonstrating a practical link with a possible 100 kbps data transmission capability.

This thesis presents an investigation into designs and developments of indoor visible light communication (VLC) systems using orthogonal frequency division multiplexing (OFDM) schemes. The novel contribution of this thesis is a development of a visible light communication system that incorporates OFDM and imaging-diversity multiple-input multiple-output (MIMO) techniques, which allows robust transmissions on multiple channels at high data rates. The characteristics of VLC systems are presented, one of which is VLC communications channel exhibits high Signal-to-Noise Ratio (SNR). The major constraint however, is the low modulation bandwidth of typical high power white LED sources. The performance of OFDM as a modulation scheme is investigated. OFDM offers the possibility for bit and power loading to increase bandwidth efficiency, as well as a straightforward equalisation in time and frequency domains to compensate the low pass frequency response of the LED. This allows transmission rates of up to ~310Mbps at a BER of 2x10-3 on a single-channel link using 16- QAM DCO-OFDM. Further increase in data rates for this transmission is constrained by the available signal power due to a dynamic range limitation at the receiver. An increase in signal power will results in the OFDM waveform to be clipped, which incurs a clipping noise. MIMO systems offer a linear capacity gain to a number of transmission channels in an ideal configuration. These systems mitigate the dynamic range limitation, as power is divided between multiple channels. The performance of a MIMO transmission system is investigated under the same dynamic range constraint. A 4-channel MIMO transmitter is built using four sets of transmitter components of the single-channel link. An imaging system is used to separate the received optical power onto multiple detectors, and MIMO processing relaxes the requirements for precise mechanical alignments. The experiment has shown that the imaging MIMO system further improves data rates and transmissions of up to ~1.1Gigabit/s at a BER of 2x10-3 are achieved. To the best of the author’s knowledge, this is the highest reported for an indoor VLC MIMO-OFDM transmission. Also presented is an analysis of MIMO system scalability to provide room-wide coverage. Finally, this thesis presents an extended analysis of several other optical OFDM approaches, and concludes with recommendations of future work to increase the data rates of indoor VLC systems.

Full textAbstract:
On reconnaitra volontiers dans l'oeuvre de michel foucault une rupture fondamentale entre histoire de la folie et ses travaux precedents. En effet, ce livre publie en 1961 finit par mettre en cause la tentative d'atteindre la verite fondamentale de l'etre humain, tentative qui se trouvait justement au coeur de ses textes des annees cinquante. Or, le rejet de la reflexion anthropologique marquant ainsi clairement un tournant decisif de la pensee << foucaldienne >>, l'etude sur l'experience de la folie est animee par le meme theme qui commandait aux textes << prehistoriques >> de foucault, a savoir le theme de la contestation d'un positivisme : rapproche objectiviste, qui etait denoncee comme incapable de saisir la subjectivite originaire de l'etre humain, y est egalement refutee pour avoir aliene folie. Et que ce theme soit persistant est d'autant plus remarquable que foucault, cherchant a elaborer la methode de ses recherches historiques, se declarera lui-meme << positiviste heureux >> dans l'archeologie du savoir. Sa relation au positivisme, coherente jusque dans histoire de la folie, change d'une maniere manifeste dans l'oeuvre de 1969. Cela n'indique-t-il pas la necessite de reperer une autre coupure dans sa pensee, qui n'est sans doute pas moins importante que celle qu'on reconnait d'ordinaire ? il semble en effet qu'en analysant les formations historiques des configurations de savoir dans la culture occidentale, ses travaux des annees soixante tournent autour de cet effort pour se detacher de ce dont il etait tributaire. Notre etude vise a les caracteriser comme << epreuve modificatrice de soi-meme >>, epreuve qui constituerait pour foucault un exercice philosophique par excellence.

Cette thèse s'intéresse à l'étude d'un double processus catalytique, la catalyse à l'or et la photocatalyse. Nous avons cherché à synthétiser des dérivés enzofuranique à partir d'o-alkynylphénols et de sels d'aryle diazonium ou d'iodoalcynes en présence d'un mélange catalytique d'un complexe d'or (I) et d'un photocatalyseur sous irradiation à la lumière visible. Dans un premier temps, nous présentons un nouveau procédé de catalyse duale photoredox/or par cyclisation arylative d'o-alkynylphénols avec des sels d'aryle diazonium. Cette réaction s'effectue dans des conditions douces à température ambiante en l'absence de base et/ou d'additifs et offre une approche efficace pour la formation de squelettes hétérocycliques. La réaction proposée fait intervenir un intermédiaire vinyl or(III) formé par addition du radical aryle sur le catalyseur d'or et par modulation de l'état d‟oxydation du complexe par le photocatalyseur. Après élimination réductrice le produit de couplage hétérocyclique est obtenu. Dans un deuxième temps, nous avons mis au point une nouvelle méthode pour la synthèse de dérivés alcynylbenzofuraniques élaborés à partir d'o-alkynylphénols et d'iodoalkynes en présence d'un mélange catalytique d'Au (I) et d'Ir (III) sous irradiation de LEDs bleues. Sous irradiation à la lumière visible, le triplet excité de l'intermédiaire vinyl-or(I) et de l'iodure d‟alcyne partenaire s'engage facilement dans une séquence d'isomérisation par addition trans-cis-oxydante, enfin l'élimination réductrice permets la formation des produits de couplage croisé Csp2-Csp. Les études mécanistiques et de modélisation ont mis en évidence un phénomène de transfert d'énergie plutôt qu'un processus redox. Ce double procédé catalytique or/photoredox fournit un nouveau mode d'activation dans la catalyse homogène à l'orThis thesis has focused on the study of a dual catalytic process involving gold catalysis and photocatalysis. We aimed to synthesize benzofuran derivatives from o-alkynylphenols and aryl diazonium salts or iodoalkynes in the presence of a catalytic mixture of a gold(I) complex and a photocatalyst under visible light irradiation. Firstly, we present a novel dual photoredox/gold catalysis process by arylative cyclization of o-alkynylphenols with aryldiazonium salts. This reaction occurs smoothly at room temperature in the absence of base and/or additives and offers an efficient approach to heterocyclic scaffolds. The reaction is proposed to proceed through a photoredox-promoted generation of a vinylgold(III) intermediate, formed by addition of the aryl radical to the gold catalyst and modulation of the oxidation state by the photocatalyst, which undergo reductive elimination to provide the heterocyclic coupling adduct. Later, we developed a new method for the synthesis of valuable alkynyl benzofuran derivatives devised from o-alkynylphenols and iodoalkynes in the presence of a catalytic mixture of Au(I) and Ir(III) under blue LED irradiation. Under visible light irradiation, the triplet excited state of the vinylgold(I) intermediate and the alkynyl iodide partner readily engaged in a oxidative addition–trans/cis isomerization sequence, deliver Csp2-Csp cross coupling products after reductive elimination. An energy transfer event rather than a redox pathway was demonstrated by the mechanistic and modeling studies. This dual gold/photo catalytic process provides a novel mode of activation in gold homogenous catalysis

Among the requirements for a modern airplane is a requirement of their low visibility, i.e. low reflectivity with respect to electromagnetic radiation. The reflectivity of the airplane is determined primarily by their construction and dielectric properties of their surface materials.

"Vision is regarded as the most noble of the senses, and the loss of eyesight as the ultimate physical loss" -- Juhani PallasmaaTo see or not to see? As a child growing up in the Dominican Republic, my vision was blurred by a perception strongly held by my elders. A perception that have been nurtured and carried out for many centuries. This perception have kept me away from the \'reality\', limiting my vision to what existed in the other side of the borderline. As my eyes were blindfolded, my ears opened to received words that would slowly construct my own imaginary world. A particular world, in which hearing was dominant over my other senses. As one would imagine that a world could painful while living in \'darkness\', what was actually painful was living with the existence of the unknown, of the invisible.
In April 2011, I decided to visit the imaginary line that runs along Dominican Republic and Haiti. My experience was truly remarkable. At that present moment, I had a very exciting encounter with a new sense of reality. As I approached to an unfinished construction, I climbed to a metal stair reaching an altitude of nearly twenty feet. My eyes witnessed what was hidden for nearly thirty years of my existence. Through the wavy transparent mirage caused by the refraction of the blistering sun, I was able to see the neighboring country of Haiti for the first time. Along the Massacre River, there was an element that immediately captivated by curiosity. It was a thin, blue metal gate located right in the middle of a concrete bridge that expanded east and west uniting the border towns of Dajabon and Ounaminthe. To my eyes, this gate was a visible and an invisible boundary -- A line, a remarkably powerful, and fundamental element in Architecture -- which was strongly visible, by dividing and marking its presence demarcating territories. Yet, was also transparent uniting two cultures during the market days.
My thesis unfolds in the quest of what can exist by the emergence of the visible and the invisible -- what I envisioned while standing at the site, a Binational Market along the imaginary line.

Full textAbstract:
Dans le cadre du modèle standard du Big Bang, le deutérium est l'élément dont l'abondance primordiale est la plus sensible à la densité baryonique de l'Univers. Cet élément est uniquement créé lors de la nucléosynthèse primordiale, quelques minutes après le Big Bang ; aucune théorie standard n'en prédit actuellement d'autres sources significatives. Au contraire, étant brûlé dans les étoiles, son abondance D/H décroît au cours de l'évolution cosmique. Les mesures de D/H apportent ainsi des contraintes sur les modèles de Big Bang et d'évolution chimique des galaxies. On peut distinguer trois types de mesures de D/H : les abondances primordiale, proto-solaire et interstellaire, respectivement représentatives de l'Univers il y a environ 15 milliards d'années, 4.5 milliards d'années et à l'époque actuelle. Si l'évolution du deutérium semble qualitativement claire, les résultats concernant ces trois types d'abondance ne convergent pas pour l'instant vers trois valeurs bien définies. Les travaux entrepris durant cette thèse sont reliés à la mesure de l'abondance interstellaire du deutérium. Celle-ci s'obtient habituellement par l'observation spectroscopique en absorption des séries de Lyman de l'hydrogène et du deutérium. Ces observations se font dans le domaine ultraviolet, au moyen d'observatoires spatiaux. Les résultats présentés ici ont été obtenus avec le Télescope spatial Hubble puis le satellite FUSE, récemment mis en orbite. D'autre part, une nouvelle méthode d'observation du deutérium a été proposée, dans le domaine visible à partir de télescopes au sol. Ce travail a mené aux premières détections et à l'identification de la série de Balmer du deutérium, observée en émission dans des régions HII avec le Télescope Canada-France-Hawaii et le Very Large Telescope.

Full textAbstract:
Visible light communication (VLC) is an emerging optical wireless communication technology that employs the light-emitting diode (LED) as the data transmitter. It has great potential to alleviate the strain on the radio-frequency (RF) spectrum in the indoor environment. The integration of VLC into indoor communication networks establishes optical attocells, responsible for the downlink traffic from the network to user terminals. These attocells could be easily deployed wherever LEDs are adopted for general illumination, including in electromagnetic interference sensitive areas like hospitals and airplanes. Although opaque bounds effectively contain light signals, VLC attocells would generally not operate free of interference. Illumination designers aim to have a uniform illumination at a certain height in the indoor environment, which mandates a rich overlap between the emissions of luminaires and results in unavoidable inter-attocell interference (IAI) from a communications perspective. This reality encourages us to propose the coordination of multiple VLC attocells (i.e., VLC-enabled LED luminaires) to turn the problem of overlap and thus interference into an advantage. In this thesis, we study how the coordination of VLC attocells can be employed to improve the user performance. Two coordinated VLC architectures, both of which utilize single-carrier transmission but differ at the coordination level, are investigated first. The analysis primarily focuses on the beamforming design subjected to the limited dynamic range of LED transmitters. The design of robust beamformers is also considered to combat the uncertainty of channel information at the transmitter. Finally, we propose a multi-carrier coordinated VLC architecture that uses power lines as the backbone network for the VLC front-end. Several subcarrier allocation schemes with varying degrees of tradeoff among hardware, computational complexity, and performance for meaningful variations of this hybrid system are proposed. The system designs developed throughout the thesis enable the collaboration among multiple LED transmitters in VLC systems, and our results indicate that these collaborative designs can significantly improve the performance of indoor VLC systems.Applied Science, Faculty of

Full textAbstract:
During the last decade, there has been an increase in the number of automated programs (bots) that perform tasks such as harvesting information or making posts on social media. CAPTCHA was developed as a defense against bots, but several common CAPTCHAs have usability issues and are difficult for users to solve. This project aims to determine if a non-visible user input-based CAPTCHA can help solve this problem. The CAPTCHA looks for patterns in the user input, that is, signs that the input is controlled by scripted logic. The CAPTCHA is evaluated by looking at how capable it is at identifying patterns, human mouse movements and bot-controlled mouse movements. Additionally, it is investigated if there exists a data sequence size at which the pattern recognition algorithm can most successfully detect patterns and avoid false negatives. The results showed that interval sizes 40-50 provide the best results. Using these sizes, the pattern recognition algorithm was able to fulfill the commonly accepted rates of at least a 99 % success rate and at most a 10 % false negative rate. This shows that the CAPTCHA is robust under the circumstances investigated.

Full textAbstract:
This research explores the notion of visual justice in relation to questions of gay identity and gay visibility. It looks at the relationship between gay identity and visual justice because the homosexual experience of social exclusion and discrimination is often described as a form of social invisibility and gay identity politics can be seen as a struggle to obtain public visibility. Moreover, it argues that in late-capitalist or spectacular societies, social dynamics connected to visual matters and regimes of visuality have increasing salience, and the lack of visual representations and/or misrepresentation of gays in mainstream culture and society is a form of injustice that needs to be seriously addressed. This thesis analyses and critically questions the relationship between gay identity and forms of visibility. To study these issues the thesis considers the media event produced by the broadcast of the first entirely gay TV drama Queer as Folk. The programme's explicit visions of gayness triggered a heated public debate on questions of gay visibility. Some viewers saw it as an obscene programme which was rendering public matters that were better kept 'private', whilst some others welcomed it as an example of a more democratic widening of the representational arena, and as a symptom of greater social inclusion and acceptance of gays in mainstream culture and society. By examining and evaluating the public discourses around Queer as Folk this research articulates a wider sociological investigation into the relationship between gay identity and the representational field. It aims to gain an understanding of social inclusion and social justice in visually mass mediated societies. It interrogates current visions of social justice based on the opposition of symbolic and material social processes and challenges the separation of recognitive and redistributive claims for justice. It assesses risks and potentials of representational visibility, imagining new visions of democracy.

The amalgamation of the technologies of Microfabrication and Rapid Prototyping and Manufacturing is a field that has witnessed a surge of research activity in recent years. This thesis demonstrates the development of a novel microfabrication system characterised by the use of Computer Generated Holograms (CGHs) as part of a StereoLithographic rapid prototyping system in cohesion with applied microfabrication techniques. CGHs are reconstructed using a laser diode operating at a visible wavelength (407nm) and subsequently implemented in the fabrication of a microstructure. The hologram encoding method utilized two-pixel macropixels implemented on a smectic, analogue ferroelectric liquid crystal (AFLC) spatial light modulator (SLM). This, in conjunction with the bipolar nature of the modulating device, allows for full complex optical modulation. A commercial photopolymer is chosen as the target material. The underlying chemical processes comprising its photochemical behaviour in its native state, as well as in the presence of sensitizers or visible light photoinitiators, are described and the suitability of each to the StereoLithographic processes evaluated. Experimental determination of the effect of such holograms on the target material is undertaken, which include nondegenerate four wave mixing to investigate optical characteristics and cure depth measurement techniques to evaluate photochemical response. The beneficial effects of using a visible light source with respect to the final physical properties of the component are determined. Final product microstructures displaying a variety of topologies are experimentally realised, accompanied by descriptions of their respective fabrication techniques and formulation requirements

Best possible performance of the device is characterized, effects of noise and filtering techniques are observed, and results from several organic films are tested. The implemented device is optimized for cost, spectral reconstruction quality is tested, and guidelines for optimal device performance are proposed.

This thesis presents a collaborative human-machine crowdmapping approach to creating socio-spatial maps that represent both spatial and social aspects of communities. Our implemented system combines satellite image analytics, a mobile mapping app, and social survey data. The system is designed to provide an end user experience that aligns institutional interests with grassroots interests, resulting in a self-sustaining system. In collaboration with the global health organization Partners in Health, we tested our approach with local health workers in Rwanda. Better maps can improve local visibility and empower communities to share knowledge, trade goods, and access medical services. Assisted by automatically annotated satellite maps, the community-driven mapping resulted in detailed spatial and social maps for four rural villages. With the collected data, we designed a novel socio-spatial map for this community that combines knowledge about household locations, paths, inhabitants of those homes, and social relations between residents. Generalizing from this map, we propose a framework to organize people, places, paths, and relationships to reason about the intersection of social and spatial mapping. Furthermore, we derive design characteristics of our human-machine mapping system that can guide the development of new systems in related contexts. Socio-spatial maps have the potential to be used as critical decision-making tools for individuals and organizations alike.

In this thesis we present a Security Application based on Visible Light Communication(VLC). As VLC continues to develop, the need to protect valuable informationtransmitted using this type of communication is also growing. We aim to protect thisvaluable information by proposing a security application in which the data is encryptedin a multiple-light system and only recoverable in specific locations of a movingpattern within specific time. We use the Shamir Secret Sharing algorithm as basis forthe encryption combined with additional algorithms to provide a more securetransmission. The application is formed by the Physical Layer which is in charge ofproviding the optimal configuration for transmission and the Application Layer inwhich we implement the encryption and decryption algorithms for the application.The Physical Layer is formed by a group of LED bulbs controlled by an FPGA usingPWM to represent the information. We propose a scheduling algorithm in which thelights are scheduled in a bit-by-bit manner. The reception part is formed by theOPT101 optical receiver connected to the ultra-low power TS881 comparator. Asecond FPGA is in charge of demodulating the signals from the comparator bymeasuring the period of each signal to detect the corresponding bit. To evaluate theSecurity Application and to find best configurations for the Physical Layer we performa series of experiments in which we modify the responsivity of the receiver underdifferent scenarios including variations of transmission angles, data rates, and heights.The results show that adjusting the sensitivity of the receiver plays a major role in theapplication as we shows different types of configurations to adjust the areas in whichthe information can be received.

People with visible facial difference often experience other people reacting negatively to their appearance. For many, this is part of everyday life. Research has identified social support as critical in adaptation processes. This is the case both for those whose facial difference was apparent at birth, and those who experienced injury or illness. There is a lack of a comprehensive theoretical construct for exploring how personal communities provide resources needed by adults to live well with visible facial difference. The combination of semi-structured interviews and creation of personal community maps provided opportunities to explore the interplay between respondent accounts and patterns of relationships people are embedded within. Seventeen adults with visible facial difference and two unaffected ‘significant others’ were interviewed. The findings provide evidence that personal communities are important social spaces for negotiation of resources that enable adults to feel connected, valued and safer within wider communities. Social support was not described as a property of the individual, but as experienced with combinations of people that change according to situation, place, or time. A diversity of personal community patterns were found, largely consistent with findings from Spencer and Pahl (2006), with one variation which increased intimate support. Some personal communities were less supportive and consequently people were at risk of isolation. Processes within personal communities were helpful both in dealing with negative social environments and in helping establish different versions of ‘normal’ life. The importance of focussing on social contexts, when seeking to understand how people live with visible facial differences, is highlighted.

Full textAbstract:
As video games have become have become more popular and as popular as music and movies, the need for more video game developers have increased also. But even though there are more people developing video games, there still exists usability issues in video games like also in general computer software. The purpose of the thesis is to find out how usability issues can be seen in video games.
To find out the answer for this research question, research was done as literature review. There already existed a fair amount of literature relating to usability issues of video games. Also the usability issues of computer software were discussed a little bit as video games are similar to computer software. The research on existing literature provided usability issues to be discussed and to find out the answer.

Full textAbstract:
A visualização em tempo real de cenas complexas através de ambientes de rede é um dos desafios na computação gráfica. O uso da visibilidade pré-computada associada a regiões do espaço, tal como a abordagem dos Potentially Visible Sets (PVS), pode reduzir a quantidade de dados enviados através da rede. Entretanto, o PVS para algumas regiões pode ainda ser bastante complexo, e portanto uma estratégia diferente para diminuir a quantidade de informações é necessária. Neste trabalho é introduzido o conceito de Smart Visible Set (SVS), que corresponde a uma partição das informações contidas no PVS segundo o ângulo de visão do observador e as distâncias entre as regiões. Dessa forma, o conceito de “visível” ou de “não-visível” encontrado nos PVS é estendido. A informação referente ao conjunto “visível” é ampliada para “dentro do campo de visão” ou “fora do campo de visão” e “longe” ou “perto”. Desta forma a informação referente ao conjunto “visível” é subdividida, permitindo um maior controle sobre cortes ou ajustes nos dados que devem ser feitos para adequar a quantidade de dados a ser transmitida aos limites impostos pela rede. O armazenamento dos SVS como matrizes de bits permite ainda uma interação entre diferentes SVS. Outros SVS podem ser adicionados ou subtraídos entre si com um custo computacional muito pequeno permitindo uma rápida alteração no resultado final. Transmitir apenas a informação dentro de campo de visão do usuário ou não transmitir a informação muito distante são exemplos dos tipos de ajustes que podem ser realizados para se diminuir a quantidade de informações enviadas. Como o cálculo do SVS depende da existência de informação de visibilidade entre regiões foi implementado o algoritmo conhecido como “Dual Ray Space”, que por sua vez depende do particionamento da cena em regiões. Para o particionamento da cena em uma BSP-Tree, foi modificada a aplicação QBSP3. Depois de calculada, a visibilidade é particionada em diferentes conjuntos através da aplicação SVS. Finalmente, diferentes tipos de SVS puderam ser testados em uma aplicação de navegação por um cenário 3D chamada BSPViewer. Essa aplicação também permite comparações entre diferentes tipos de SVS e PVS. Os resultados obtidos apontam o SVS como uma forma de redução da quantidade de polígonos que devem ser renderizados em uma cena, diminuindo a quantidade de informação que deve ser enviada aos usuários. O SVS particionado pela distância entre as regiões permite um corte rápido na informação muito distante do usuário. Outra vantagem do uso dos SVS é que pode ser realizado um ordenamento das informações segundo sua importância para o usuário, desde que uma métrica de importância visual tenha sido definida previamente.
