Description
Este trabajo examina la producción literaria y cultural chicana/méxicosudoesteña de las distintas épocas coloniales del sudoeste: la época colonial española (1521-1821), la época colonial angloamericana (1848-1965) y la época poscolonial (1965-presente) para ver hasta qué punto siguen vigentes los legados coloniales dentro de un contexto contemporáneo. Avanzamos la hipótesis que, de la larga residencia histórica y geográfica de las personas hispanomexicanas en el sudoeste, se han producidos textos simbólicos donde se registran dos o más discursos residuos cuyo origen es una ideología dominante. El capítulo 1 plantea y detalla la hipótesis, reseña los numerosos estudios existentes, describe el marco teórico y da la división en capítulos. En el capítulo 2, se da de manera detallada el método crítico: la definición del colonialismo clásico según la teoría de Mario Barrera, la relación colonizador/colonizado aportada por Albert Memmi y los conceptos del tercer espacio híbrido, el mestizaje y el imaginario decolonial asociados con la época poscolonial como ofrecidos respectivamente por Homi Bhabha, Rafael Pérez-Torres y Emma Pérez. El capítulo 3 ofrece un análisis de la época colonial española vía dos obras nuevomexicanas: el poema épico Historia de la Nueva México (1610) de Gaspar Pérez de Villagrá y el drama Los comanches (c.1779) de anónimo. El capítulo 4 trata la colonización angloamericana en las obras The Squatter and the Don (1885) de María Amparo Ruiz de Burton y Dew on the Thorn (escrita en los 1940; publicada en 1997) de Jovita González de Mireles. El capítulo 5 examina la época poscolonial vía la obra Los muertos también cuentan (1995) de Miguel Méndez. Una lectura de la literatura chicana/méxicosudoesteña revela la presencia de varios personajes típicos asociados cada uno a una diferente época histórica desde el conquistador español hasta un mexicano recién inmigrado, quienes no han podido evadir la correspondiente presencia de un grupo dominante u colonizador. Con base en una investigación de las cinco obras seleccionadas, se muestra cómo las relaciones coloniales se forman y se transforman y luego se manifiestan en un contexto contemporáneo, desplazando por ende nuestro entendimiento de las relaciones coloniales como un simple proyecto binario de dominación y subordinación.

Description
Set in the former Yugoslavia, contemporary Bosnia and Herzegovina, and Midwest America, the collection of short stories follows the complicated trajectory of war-survivor to refugee and, then, immigrant. These stories---about religious prisoners who are not at all religious, about young, philosophizing boys tempting the bullets of snipers, about men retracing their fathers' steps over bridges that no longer exist---grapple with memory, imagination, and the nature of art, and explore the notion of writer as witness.

Description
One of the main challenges in planetary robotics is to traverse the shortest path through a set of waypoints. The shortest distance between any two waypoints is a direct linear traversal. Often times, there are physical restrictions that prevent a rover form traversing straight to a waypoint. Thus, knowledge of the terrain is needed prior to traversal. The Digital Terrain Model (DTM) provides information about the terrain along with waypoints for the rover to traverse. However, traversing a set of waypoints linearly is burdensome, as the rovers would constantly need to modify their orientation as they successively approach waypoints. Although there are various solutions to this problem, this research paper proposes the smooth traversability of the rover using splines as a quick and easy implementation to traverse a set of waypoints. In addition, a rover was used to compare the smoothness of the linear traversal along with the spline interpolations. The data collected illustrated that spline traversals had a less rate of change in the velocity over time, indicating that the rover performed smoother than with linear paths.

Description
A simple passion for reading compels many to enter the university literature classroom. What happens once they arrive may fuel that passion, or possibly destroy it. A romanticized relationship with literature proves to be an obstacle that hinders a deeper and richer engagement with texts. Primary research consisting of personal interviews, observations, and surveys, form the source of data for this dissertation project which was designed to examine how literature teachers engage their students with texts, discussion, and assignments in the university setting. Traditionally text centered and resolute, literature courses will need refashioning if they are to advance beyond erstwhile conventions. The goal of this study is to create space for a dialogue about the need for a pedagogy of literature.

Description
As the complexity of robotic systems and applications grows rapidly, development of high-performance, easy to use, and fully integrated development environments for those systems is inevitable. Model-Based Design (MBD) of dynamic systems using engineering software such as Simulink® from MathWorks®, SciCos from Metalau team and SystemModeler® from Wolfram® is quite popular nowadays. They provide tools for modeling, simulation, verification and in some cases automatic code generation for desktop applications, embedded systems and robots. For real-world implementation of models on the actual hardware, those models should be converted into compilable machine code either manually or automatically. Due to the complexity of robotic systems, manual code translation from model to code is not a feasible optimal solution so we need to move towards automated code generation for such systems. MathWorks® offers code generation facilities called Coder® products for this purpose. However in order to fully exploit the power of model-based design and code generation tools for robotic applications, we need to enhance those software systems by adding and modifying toolboxes, files and other artifacts as well as developing guidelines and procedures. In this thesis, an effort has been made to propose a guideline as well as a Simulink® library, StateFlow® interface API and a C/C++ interface API to complete this toolchain for NAO humanoid robots. Thus the model of the hierarchical control architecture can be easily and properly converted to code and built for implementation.

Description
En el siglo XXI nuestra vida se está cruzando constantemente con la tecnología, tanto que algunos declaran que nuestro mundo se ha hecho posthumano, ya que no se puede separar al ser humano de la máquina. Aunque algunos se sientan amenazados por estas tecnologías, otros están abrazando la Red Mundial, aprovechándose de las infinitas oportunidades que ofrece. Uno de estos elementos fundamentales que internet posibilita es la capacidad de comunicarse directamente con otras personas. El blog por ejemplo, o bitácora en español, permite que los usuarios se proyecten a sí mismos o a sus pseudo-identidades, sus pensamientos e ideas a través del texto que escriben en internet. También sus lectores pueden responder a estos autores inmediatamente. Los posts publicados--entradas en una página web--, aunque aparecen cronológicamente, son episodios fragmentados. Pero el blog no se limita a la producción de un texto sino que el autor puede también "jugar" con el cuerpo del texto para añadir hipervínculos y multimedia. Esta forma de escribir está cambiando lo que se considera "válido" como texto, incluso lo que se considera literatura. El objetivo de este trabajo no es estudiar la literatura digital en su totalidad, sino específicamente en algunas obras escritas por mujeres en internet. Si se considera la escritura digital como una forma de arte marginalizada, se podría decir que la escritura realizada por mujeres en internet experimenta una doble-marginalidad debido al hecho de que la literatura de mujeres siempre ha sido marginal al canon. Este estudio tomará un punto de vista transatlántico, incluyendo en el mismo a varias escritoras hispanohablantes de diferentes edades, experiencias y con variados motivos en su trabajo que publican sus obras en internet. Estas autoras incluyen las blogueras Almudena Montero (española) yMaría Amelia López Soliño (española); la periodista ciudadana Yoanis Sánchez (cubana); y la poeta digital/crítica Belén Gache (española-argentina). En esta tesis he explorado y considerado la noción de que el internet sirve como un medio de democratización puesto que, hasta cierto punto, las fronteras de género y nacionalidad desaparecen. Por esta razón, este trabajo va a considerar varias teorías tales como el postmodernismo, las teorías sobre la escritura de mujeres y teorías sobre la democratización de la tecnología para analizar la literatura que se encuentra en la red. Aunque las escritoras analizadas en este proyecto son distintas, y usan la tecnología de maneras diferentes, tienen una misma meta: expresarse libremente y comunicarse directamente con sus lectores al conectarse a internet. Mi hipótesis de trabajo consiste en que estas mujeres escriben de una manera particular--es decir, que no escriben igual a los hombres que escriben en internet--y que la red ofrece una plataforma única a las mujeres: en este espacio ellas son más activas--en oposición a la literatura tradicional-- en cuanto a compartir y publicar su propio trabajo e ideas.

Description
This dissertation considers the literary and cultural response of the labor-class poets to the emerging forces of Foucauldian biopolitics in early modern Britain to shed new light on the cultural impacts of biopower upon the rural community in early modern Britain. The analysis demonstrates how the labor class literary response is characterized by an exterior experience with the nonhuman in an alternative mode to the Wordsworthian experience of the interior. I then use labor-class poets to counter Wordsworthian notions of the immaterial State population through a critical expose of state-Subject, subject-object, and human nonhuman exterior relations as they are depicted in the labor-class poetry of late eighteenth and early nineteenth century Britain. Employing an object-ontological reading of community, I explore how the effects of biopower were inscribed in the literary artifacts of the labor-class. As a final consideration, I explore the response to postcolonial biopolitics in J.M. Coetzee's 1999 novel, Disgrace. The research takes a focused historical view, surveying a range of literary, political, and historical texts between 1760-1840 to offer new readings of Robert Bloomfield, Robert Burns, John Clare, William Cobbett, Ebenezer Elliott, Olivier Goldsmith, James Hogg, and William Wordsworth. In complement, the research offers a new reading of postcolonial biopolitics in the contemporary work of J.M Coetzee.

Description
In this collection of stories, people find themselves face to face with great trouble: a house lost to flood, a brother lost to the river, a girl on the edge of an adulthood she can't possibly survive. Set in Northern California along the banks of the Sacramento and American Rivers, the stories feature characters who live below the radar of the middle-class. Central to the narratives are notions of loss, lust, pleasure, and struggle.

Description
The development of advanced, anthropomorphic artificial hands aims to provide upper extremity amputees with improved functionality for activities of daily living. However, many state-of-the-art hands have a large number of degrees of freedom that can be challenging to control in an intuitive manner. Automated grip responses could be built into artificial hands in order to enhance grasp stability and reduce the cognitive burden on the user. To this end, three studies were conducted to understand how human hands respond, passively and actively, to unexpected perturbations of a grasped object along and about different axes relative to the hand. The first study investigated the effect of magnitude, direction, and axis of rotation on precision grip responses to unexpected rotational perturbations of a grasped object. A robust "catch-up response" (a rapid, pulse-like increase in grip force rate previously reported only for translational perturbations) was observed whose strength scaled with the axis of rotation. Using two haptic robots, we then investigated the effects of grip surface friction, axis, and direction of perturbation on precision grip responses for unexpected translational and rotational perturbations for three different hand-centric axes. A robust catch-up response was observed for all axes and directions for both translational and rotational perturbations. Grip surface friction had no effect on the stereotypical catch-up response. Finally, we characterized the passive properties of the precision grip-object system via robot-imposed impulse perturbations. The hand-centric axis associated with the greatest translational stiffness was different than that for rotational stiffness. This work expands our understanding of the passive and active features of precision grip, a hallmark of human dexterous manipulation. Biological insights such as these could be used to enhance the functionality of artificial hands and the quality of life for upper extremity amputees.

Description
Human fingertips contain thousands of specialized mechanoreceptors that enable effortless physical interactions with the environment. Haptic perception capabilities enable grasp and manipulation in the absence of visual feedback, as when reaching into one's pocket or wrapping a belt around oneself. Unfortunately, state-of-the-art artificial tactile sensors and processing algorithms are no match for their biological counterparts. Tactile sensors must not only meet stringent practical specifications for everyday use, but their signals must be processed and interpreted within hundreds of milliseconds. Control of artificial manipulators, ranging from prosthetic hands to bomb defusal robots, requires a constant reliance on visual feedback that is not entirely practical. To address this, we conducted three studies aimed at advancing artificial haptic intelligence. First, we developed a novel, robust, microfluidic tactile sensor skin capable of measuring normal forces on flat or curved surfaces, such as a fingertip. The sensor consists of microchannels in an elastomer filled with a liquid metal alloy. The fluid serves as both electrical interconnects and tunable capacitive sensing units, and enables functionality despite substantial deformation. The second study investigated the use of a commercially-available, multimodal tactile sensor (BioTac sensor, SynTouch) to characterize edge orientation with respect to a body fixed reference frame, such as a fingertip. Trained on data from a robot testbed, a support vector regression model was developed to relate haptic exploration actions to perception of edge orientation. The model performed comparably to humans for estimating edge orientation. Finally, the robot testbed was used to perceive small, finger-sized geometric features. The efficiency and accuracy of different haptic exploratory procedures and supervised learning models were assessed for estimating feature properties such as type (bump, pit), order of curvature (flat, conical, spherical), and size. This study highlights the importance of tactile sensing in situations where other modalities fail, such as when the finger itself blocks line of sight. Insights from this work could be used to advance tactile sensor technology and haptic intelligence for artificial manipulators that improve quality of life, such as prosthetic hands and wheelchair-mounted robotic hands.
