This thesis reconstructs the genre of urban satirical pamphleteering. It contends that the pamphlets of Robert Greene, Thomas Nashe, Thomas Dekker, Thomas Middleton, and Barnaby Rich are stylistically and generically akin. Writing in a relatively undefined form, these pamphleteers share an interest in describing contemporary London, and employ an experimental style characterised by its satirical energy. In addition, they negotiate a series of tensions between profitability and play. In the early modern period, ‘profit' was variously conceived as financial, moral, or rooted in public service. Pamphleteers attempted to reconcile these senses of profitability. At the same time, they produced playful works that are self-consciously mocking, that incorporate alternative perspectives, and that are generically hybrid. To varying degrees, urban satirical pamphlets can be defined in relation to the concepts of profitability and play. Chapter One introduces the concept of moral profitability through an examination of Elizabethan moralistic pamphlets. In particular, it analyses the anxious response to profitability contained in Philip Stubbes's Anatomie of Abuses (1583). Chapter Two argues that Greene disrupted appeals to totalising profitability, and instead demonstrated the alternative potential of play. Chapter Three examines Nashe's notoriously evasive pamphlets, contending that he embraced play in response to the potential profitlessness of pamphleteering. Chapter Four argues that although Dekker and Middleton rejected absolutist notions of profitability, their pamphlets redirect stylistic play towards compassionate social commentary. Finally, Chapter Five explores Rich's relocation of moralistic conventions in pamphlets that are presented as both honest and mocking. Taken as a whole, this thesis re-evaluates the style and genre of urban satirical pamphleteering. It reveals that this frequently overlooked literary form was deeply invested in defining and critiquing the purpose of literature.

Des robots sociaux tels que Pepper sont déjà présents "dans la nature". Leur comportements sont adaptés à chaque cas d'usage par des experts. Permettre au grand public d'enseigner de nouveaux comportements pourrait mener à une meilleure adaptation à moindre coût. Dans cette thèse nous étudions un système cognitif et des comportements robotiques permettant à des utilisateurs de Pepper à domicile de composer de nouveaux comportements à partir de comportements existants, par le langage parlé. Les domiciles sont des mondes ouverts qui ne peuvent pas être prédéterminés. Pepper doit donc, en plus d'apprendre de nouveaux comportements, être capable de découvrir son environnement, et de s'y rendre utile ou de divertir : c'est un scénario riche. L'enseignement de comportements que nous démontrons s'effectue donc dans ces conditions uniques : par le seul langage parlé, dans des scénarios riches et ouverts, et sur un robot Pepper standard. Grâce à la transcription automatique de la parole et au traitement automatique du langage, notre système reconnaît les enseignements de comportement que nous n'avions pas prédéterminés. Les nouveaux comportements peuvent solliciter des entités qui auraient été appris dans d'autres contextes, pour les accepter et s'en servir comme paramètres. Par des expériences de complexité croissante, nous montrons que des conflits entre les comportements apparaissent dans les scénarios riches, et proposons de les résoudre à l'aide de planification de tâche et de règles de priorités. Nos résultats reposent sur des méthodes qualitatives et quantitatives et soulignent les limitations de notre solution, ainsi que les nouvelles applications qu'elle rend possible
Social robots like Pepper are already found "in the wild". Their behaviors must be adapted for each use case by experts. Enabling the general public to teach new behaviors to robots may lead to better adaptation at lesser cost. In this thesis, we study a cognitive system and a set of robotic behaviors allowing home users of Pepper robots to teach new behaviors as a composition of existing behaviors, using solely the spoken language. Homes are open worlds and are unpredictable. In open scenarios, a home social robot should learn about its environment. The purpose of such a robot is not restricted to learning new behaviors or about the environment: it should provide entertainment or utility, and therefore support rich scenarios. We demonstrate the teaching of behaviors in these unique conditions: the teaching is achieved by the spoken language on Pepper robots deployed in homes, with no extra device and using its standard system, in a rich and open scenario. Using automatic speech transcription and natural language processing, our system recognizes unpredicted teachings of new behaviors, and a explicit requests to perform them. The new behaviors may invoke existing behaviors parametrized with objects learned in other contexts, and may be defined as parametric. Through experiments of growing complexity, we show conflicts between behaviors in rich scenarios, and propose a solution based on symbolic task planning and priorization rules to resolve them. The results rely on qualitative and quantitative analysis and highlight the limitations of our solution, but also the new applications it enables

Every day, adversaries bombard Department of Defense computer networks with scanning traffic in order to gather information about the target network. This reconnaissance is typically a precursor to attacks designed to access data, exfiltrate information, or plant malware in order to gain a military advantage. One specific reconnaissance tool, traceroute, is used to map the network topology of a target network. We implement an active network defense tool, dubbed DeTracer, that seeks to thwart network mapping attacks through the use of deception. We deploy DeTracer in several environments, including the Internet, to demonstrate that an attacker attempting to map a target network using traceroute probes can be presented with a false network topology of the defender’s choosing. Our experiments show that a defender can present an adversary with a credible false network topology. We are able to deceive all types of incoming traceroute probes, present a complex false network topology on a per source and destination basis, and deploy our deception scheme without disrupting service to the real production infrastructure on our network.

Roberto Sebastian Matta Echaurren, artista chileno surrealista, se conoce principalmente por su trabajo pictórico. Hoy, con la presente tesis se desea mostrar, explorar, investigar y deducir cómo este artista plástico principalmente pictórico, encuentra en el grabado un camino paralelo en el desarrollo de su obra, un camino bastante desconocido hasta este momento. La tesis que se presenta parte desde los inicios de su vida y relata el transcurso en ella. Ya que todos estos factores históricos y personales son los que nos ayudarán a conocer y comprender quién es Roberto Sebastian Matta Echaurren, un artista que nunca se consideró chileno, un artista universal y un pintor al que nunca se le consideró grabador, a pesar de la cantidad y calidad de su obra gráfica. Estas últimas ideas se expresan y se exponen en profundidad posteriormente dentro de la presente tesis. Luego, la investigación presenta una explicación del por qué es el título "Visiones e influencias de un grabador desconocido" para así poder vislumbrar cómo Matta entiende y vive el arte. Y lo más relevante cómo Matta descubre el grabado, dónde, cómo, cuándo, y por qué desea expresarse en esta área artística. Y se enuncia algo muy relevante que son los reconocidos ¿atelieres¿ de grabado en los que Matta eligió trabajar. Posteriormente se indican los dos atelieres más significativos donde trabajó Matta que son: Atelier George Visat - Albert Dupont y Atelier Fernand Mourlot ¿ Frank Bordas, haciendo un énfasis en la relación de Roberto Matta y Frank Bordas ya que es a partir de esta relación y los datos que nos entregaron las fuentes directas que podremos entender y comprender cómo Matta ve el grabado. Todo lo descrito son las bases que nos guiarán a un segmento esencial de esta tesis que es el capítulo titulado ¿Pintura y Grabado". Dentro de este capítulo veremos la pintura de Matta, su obra finalizada y su proceso dentro de ella. Con el resultado de toda esta información, hacemos un paralelo pictórico y gráfico, siendo lo fundamental establecer y esclarecer si existe o no una relación entre la pintura y el grabado de Roberto Matta. La catalogación de los grabados es el núcleo de la presente tesis, siendo el primer catálogo técnico de la obra de Matta, a pesar de que esta tesis se comenzó hace mas de 5 años, aún no existe un catálogo técnico y razonado completo de su obra. Hoy se presenta un catálogo más completo que los existentes aunque no se posee aún la totalidad de su obra. Posteriormente a la catalogación de sus grabados se presenta un análisis y comentarios para comprender la obra gráfica de este artista, en ella se eligen por grado de relevancia, a nivel histórico, personal o plástico seis obras gráficas, que son: The New School, Hom¿mere, El verbo hommerica, El gran Burundi-burunda ha muerto, Don Q y Ubu Roi. Para finalizar se ha considerado interesante presentar una cronología de la vida y obra de Roberto Matta que estarán unidas a los hechos históricos chilenos y mundiales para darnos un contexto político y social importante que se ve reflejado en las obras plásticas del artista. Deseo mencionar que las ¿Visiones e influencias de un grabador desconocido¿ no es una investigación completa ni acabada, ya que, la finalización de este trabajo fue truncado por una integrante relevante de la familia del artista, no obstante se logra presentar casi un 80% de su trabajo gráfico. Siendo esta tesis el destape hacia esa parte que el artista escondía y protegía como un secreto y de la cual actualmente solo conocemos fragmentos para su comercialización. Posteriormente a la primera revision de la presente tesis por los investigadores externos, se han realizado ciertos cambios, uno es sobre la presentacion del grafico familiar y de la presentacion de las fichas, todos los cambios son a nivel grafico de la presente tesis. Finalmente aquí esta!, se la presento hoy ¿Visiones e influencias para un grabador desconocido¿ un trabajo contra el miedo, contra el olvido, contra el secreto.

The Germans of Geilenkirchen-Hengesburg region of Germany were convinced by relative and friend, Father Peter Leonard Thevis, of the Archdiocese of New Orleans, to emigrate to the United States for a number of reasons: political, religious, and economic. After establishing themselves on land previously used for grazing cattle, the Germans soon discovered rice could easily be cultivated in large amounts. Along with their success as rice farmers in Roberts Cove, Louisiana, these Germans soon involved themselves in politics and engaged one another and the surrounding community in numerous court cases. These court cases, overlooked by previous historians, demonstrate that the Germans of Roberts Cove had begun to assimilate, prior to World War I and the passage of anti-German legislation.

The forward/inverse kinematics, trajectory planning and control system for a mobile omni-directional robot are analyzed and implemented. For kinematic analysis each wheel of the robot has been modeled as a "higher pair" joint. Both the forward and inverse kinematic solutions of the robot are dealt with. The trajectory planning for the robot is done on two levels, a global robot trajectory and individual wheel trajectories. A simple, Linear Segment with Parabolic Blends, trajectory is used on the local, wheel level. On the global level the robot can be made to move along higher order trajectories. A PID control system for the robot is implemented for this purpose. Using a hierarchical control scheme the wheel encoder feedback is converted to global motion feedback. This control scheme does not account for wheel slippage.

Advances in the knowledge of chemical structure of coal and development of high performance computational techniques led to more than hundred and thirty four proposed molecular level representations (models) of coal between 1942 and 2010. These models were virtually on the carboniferous coals from the northern hemisphere. There are only two molecular models based on the inertinite- and vitrinite-rich coals from the southern hemisphere. The current investigation is based on the chars derived from the Permian-aged coals in two major South African coalfields, Witbank #4 seam and Waterberg Upper Ecca. The two coals were upgraded to 85 and 93% inertinite- and vitrinite-rich concentrates, on visible mineral matter free basis. The coals were slow heated in inert atmosphere at 20 ℃ min-1 to 450, 700 and 1000 ℃ and held at that temperature for an hour. After the HCl-HF treatment technique at ambient temperatures, the characteristics of the coals and chars were examined with proximate, ultimate, helium density, porosity, surface area, petrographic, solid-state 13C NMR, XRD and HRTEM analytical techniques. The results largely showed that substantial transitions occurred at 700-1000 ℃, where the chars became physically different but chemically similar. Consequently, the chars at the highest temperature (1000 ℃) drew attention to the detailed study of the atomistic properties that may give rise to different reactivity behaviours with CO2 gas. The H/C atomic ratios for the inertinite- and vitrinite-rich chars were respectively 0.31 and 0.49 at 450 ℃ and 0.10 and 0.12 at 1000 ℃. The true density was respectively 1.48 and 1.38 g.cm-3 at 450 ℃ and 1.87 and 1.81 g.cm-3 at 1000 ℃. The char form results from the petrographic analysis technique indicated that the 700-1000 ℃ inertinite-rich chars have lower proportions of thick-walled isotropic coke derived from pure vitrinites (5-8%) compared with the vitrinite-rich chars (91-95%). This property leads to the creation of pores and increases of volume and surface area as the softening walls expand. It was found that the average crystallite diameter, La, and the mean length of the aromatic carbon fringes from the XRD and HRTEM techniques, respectively, were in good agreement and made a definite distinction between the 1000 ℃ inertinite- and vitrinite-rich chars. The crystallite diameter on peak (10) approximations, La(10), of 37.6Å for the 1000 ℃ inertinite-rich chars fell within the HRTEM’s range of minimummaximum length boundary of 11x11 aromatic fringes (27-45Å). The La (10) of 30.7Å for the vitrinite-rich chars fell nearly on the minimum-maximum length range of 7x7 aromatic fringes (17-28Å.) The HRTEM results showed that the 1000 ℃ inertinite-rich chars comprised a higher distribution of larger aromatic fringes (11x11 parallelogram catenations) compared with a higher distribution of smaller aromatic fringes (7x7 parallelogram catenations). The mechanism for the similarity between the 700-1000 ℃ inertinite- and vitrinite-rich chars was the greater transition occurring in the vitrinite-rich coal to match the more resistant inertinite-rich coal. This emphasised that the transitions in the properties of vitrinite-rich coals were more thermally accelerated than those of the inertinite-rich coals. The similarity between the inertinite- and vitrinite-rich chars was shown by the total maceral reflectance, proximate, ultimate, skeletal density and aromaticity results. Evidence for this was the carbon content by mass for the inertinite- and vitrinite-rich chars of respectively 90.5 and 85.3% at 450 ℃ and 95.9 and 94.1% at 1000 ℃. The aromaticity from the XRD technique was respectively 87 and 77% at 450 ℃ and 98 and 96% at 1000 ℃. A similar pattern was found in the hydrogen and oxygen contents, the atomic O/C ratios and the aromaticity from the NMR technique. The subsequent construction of large-scale molecular structures for the 1000 ℃ inertinite-rich chars comprised 106 molecules constructed from a total of 42929 atoms, while the vitrinite-rich char model was made up of 185 molecules consisting of a total of 44315 atoms. The difference between the number of molecules was due to the inertinite-rich char model comprising a higher distribution of larger molecules compared with the vitrinite-rich char model, in agreement with the XRD and HRTEM results. These char structures were used to examine the behaviour on the basis of gasification reactivity with CO2. The density functional theory (DFT) was used to evaluate the interactions between CO2 and the atomistic representations of coal char derived from the inertinite- and vitrinite rich South African coals. The construction of char models used the modal aromatic fringes (fringes of highest frequencies in size distributions) from the HRTEM, for the inertinite- and vitrinite-rich chars, respectively (11x11 and 7x7 parallelogram-shaped aromatic carbon rings). The structures were DFT geometrically optimized and used to measure reactivity with the Fukui function, f+(r) and to depict a representative reactive carbon edge for the simulations of coal gasification reaction mechanism with CO2 gas. The f+(r) reactivity indices of the reactive edge follows the sequence: zigzag C remote from the tip C (Czi = 0.266) > first armchair C (Cr1 = 0.087) > tip C (Ct = 0.075) > second armchair C (Cr2 = 0.029) > zigzag C proximate to the tip C (Cz = 0.027). The DFT simulated mean activation energy, ΔEb, for the gasification reaction mechanism (formation of second CO gas molecule) was 233 kJ mol-1. The reaction for the formation of second CO molecule is defines gasification in essence. The experimental activation energy determined with the TGA and random pore model to account essentially for the pore variation in addition to the gasification chemical reaction were found to be very similar: 191 ± 25 kJ mol-1 and 210 ± 8 kJ mol-1; and in good agreement with the atomistic results. The investigation gave promise towards the utility of molecular representations of coal char within the context of fundamental coal gasification reaction mechanism with CO2.

This thesis is a narrative study that examines significant life experiences of six living artists that were pivotal in their decision to pursue careers in the arts. Although the examples found in these conversations are not exhaustive—many factors play into the individuals sense of identity and agency—they serve to give voice to the multiplicity of the learning experience, underscoring that creative education occurs in the home, the community, and among social groups as frequently as it does in the classroom. Through direct, open-ended conversations with artists, research explores the setting of upbringing and education, the pivotal experiences—catalysts—that propelled these individuals into art careers, and impact of their experience on both creative practice and notions of art learning. Interviews encompass artists whose work is located in public spaces, natural landscapes, and urban environments as often as it appears in the traditional exhibition settings, whose work is both collaborative and socially constructed. They comprise Rick Lowe, artist and founder of Project Row Houses in Houston, Texas whose community-centered social sculpture expands on our cultural assumptions about the artist and Anne Wallace, a public artist whose early work as a human right activist and bi-cultural experiences translate into videos about the complexities of the United States/Mexico border. It includes Vincent Valdez, a self-described “hyper-realist” who depicts his home city and composite life experiences of his family through allegorical paintings and drawings; Marie Lorenz, an artist explorer whose interest in urban waterways brings her work into the waters of forgotten canals and rivers; of Robert Pruitt, who critiques ever-changing political landscapes, conceptions of history, and globalism through hybrid drawings and sculptures; and Franco Mondini-Ruiz who fuses aesthetics of high and low in installations and creative economy widely accessible to people both within and outside the confines of the art world. Through narrative conversation, this thesis enriches overlapping theories that encompass our understandings of education and learning—mentorship, experiential learning, the aesthetic experience, place-based learning, communities of practice—through lived example, underscoring learning as a socially constructed phenomenon. Experiences of learning, unique and wholly individualized, contribute to a one’s sense of self and agency; in the case of the six artists featured in this study, creative experiences contribute to their identity as “artist” and motivated their pursuit of lifework and career.
