ASPECTOS FANTÁSTICOS PRESENTES EN MORIRÁS LEJOS DE JOSÉ EMILIO PACHECO

Vargas Ortiz, Juan Ignacio January 2006 (has links)
Informe de Seminario para optar al grado de Licenciado en Lengua y Literatura Hispánica mención Literatura. / La literatura fantástica ha sido objeto de numerosos estudios en vías de establecer sus límites y la consiguiente determinación de las directrices que permitan la instauración de lo fantástico como un género independiente. En ese sentido, se considera que lo fantástico está rodeado de un campo semántico constituido por signos tales como: horror, pánico, miedo, estupefacción y asombro. De esta manera es que se ha llegado a proponer como una característica propia de lo fantástico, la producción de un quiebre en la realidad representada en el relato, lo que conduciría a la duda, la vacilación, la que debe ser experimentada -según algunos autores- tanto en los personajes, como en quien lee.

Some robots are designed to perform tasks in completely inhospitable environments such as the earth´s subsurface, the ocean depths or spatial exploration. In order to consider a robot as autonomous, a fundamental premise is to have self-adaptation capabilities. Over the last years, the advances in technology allow the development of self-adaptive systems, which are able to manage themselves to recuperate from faults or even change their behavior and structure in order to improve the quality of the delivered service. A critical point when building any software is its architecture, i.e., its structural organization in a set of interacting components. In this context, reference architecture is a technique that is well known for combining the best practices, patterns and strategies for building and standardizing domain specific software. Nowadays, there is a lack of studies presenting reference architectures for structuring self-adaptive software of mobile robots in order to decrease maintenance efforts. A number of studies claim that self-adaptive systems are based on the control theory and, more specifically, on the use of control loops in their architecture to perform adaptations. Therefore, this master thesis proposes SARAMR, a control loop-based reference architecture whose goal is to make maintenance activities a more productive task. The employment of the architecture divides the whole system in two modules; base application and adaptation module. The adaptation module encompasses the control loops and the base application is further divided into three other components: environment, behaviors and the electromechanical part. SARAMR was qualitatively evaluated by means of the development of two applications: a self-adaptive wall follower mobile robot and another conventional one to performing monitoring in in-door environments. Next, some maintenance activities were created to investigate the effort of applying them. We have observed that the separation of concerns of our architecture allows new components to be added causing less impacts than in systems developed in an adhoc way. / Robôs móveis autônomos fazem parte de uma categoria especial de robôs projetados para realizar tarefas sem a intervenção de seres humanos. Alguns robôs são projetados para realizar tarefas em ambientes completamente inóspitos à vida humana como no subsolo terrestre, nas profundezas de oceanos ou na exploração espacial. Para que um robô seja considerado autônomo, uma premissa fundamental é possuir capacidades de autoadaptação. Nos últimos anos, os avanços da tecnologia possibilitaram o desenvolvimento de sistemas robóticos autoadaptativos, que são capazes de gerenciarem a si próprios, se recuperarem de falhas e também de alterarem seu comportamento e estrutura com o objetivo de otimizar e/ou manter a qualidade do serviço (QoS) oferecido. Uma questão crítica para a concepção e construção de qualquer sistema de software é sua arquitetura, isto é, sua organização estrutural em um conjunto de componentes que interagem. Nesse contexto, a utilização de arquiteturas de referência é uma abordagem conhecida atualmente por combinar as melhores práticas, padrões e estratégias para a construção e padronização de sistemas de software para um determinado domínio. Atualmente, nota-se uma carência de estudos que apresentem arquiteturas de referência para estruturar o software de robôs móveis autoadaptativos de forma a facilitar atividades de manutenção nesses sistemas. Muitos estudos apontam que sistemas autoadaptativos são baseados na teoria do controle e mais especificamente na utilização de loops de controle em sua arquitetura para realizar as adaptações. Diante disso, este trabalho propõe a arquitetura de referência SARAMR, uma arquitetura de referência baseada em loops de controle cujo objetivo é facilitar atividades de manutenção no software desses sistemas. A utilização da arquitetura divide o sistema em dois módulos: aplicação base e módulo de adaptação. O módulo de adaptação envolve os loops de controle e a aplicação base ainda é subdividida em três componentes: ambiente, comportamentos e a parte eletromecânica. SARAMR foi avaliada de forma qualitativa mediante o desenvolvimento duas aplicações: um robô autoadaptativo seguidor de paredes e um outro convencional de patrulhamento. Depois disso, algumas manutenções evolutivas foram idealizadas no sentido de averiguar o esforço de aplicá-las. Constatou-se que a separação de interesses existente na arquitetura permite que novos componentes possam ser adicionados com impacto menor do que em sistemas que não usam essa arquitetura.

Allegory and the Transnational Affective Field in the Contemporary Mexican Novel (1993-2013)

Bernal Rodríguez, Alejandra 08 October 2019 (has links)
This thesis identifies continuities and disruptions within the tradition of literary allegory in Latin America and critically revisits the category of “national allegory” (Jameson 1986) in order to articulate an interpretative model suited to contemporary “transnational allegorical fiction”. Based on the analysis of seven Mexican novels that register the transition of neoliberalism from the political-economic order to a form of biopolitical control (Althusser, Foucault, Žižek), I identify the emergence of what I call a “transnational affective field”: a symbolic horizon, alternative to the nation, where the prospective function of foundational romances (Sommer) and the retrospective function of mourning akin to postdictatorial fiction (Avelar), converge. This ideological device negotiates power relations, facilitates the transfer of local/global meaning, promotes intercultural empathy and compromise, and denounces mechanisms of exclusion; thereby, reconfiguring the affective and political functions of allegory in Latin American fiction. Part One discusses critical approaches to allegorical fiction in both Latin American and World literatures. Part Two compares the representation of the binomial nation/world in three historiographic metafictions by Carmen Boullosa, Francisco Rebolledo and J.E. Pacheco through recent approaches in post-/de-colonial and memory studies. Part Three examines the depiction of the nation as simulacrum and the figuration of postmodern subjectivities in Jorge Volpi and Juan Villoro from a poststructuralist perspective. It also contends that Álvaro Enrigue’s and Valeria Luiselli’s novels are representative of an emergent meta-allegorical imagination that, in an ironic reversal of allegory (de Man), simultaneously constructs it as a mechanism of ideological control as well as a conscious strategy to resist commodification and symbolic violence (Bourdieu) in the contemporary world. The analysis demonstrates the vitality of Mexican transnational allegorical fiction as a socio-political and affective counter-hegemonic discourse that also functions as an effective strategy of recognition in the international literary field.
