Écfrasis y Lecturas Icono-textuales en las "Leyendas" de Gustavo Adolfo Bécquer

The relationship between literature and the visual arts is ancient and it has been studied from different conceptual frames. Scholars agree that both have a descriptive function and therefore share the common goal of portraying a fictional or nonfictional reality. Based on this correspondence between two different modes of artistic expression, the Roman poet Horace coined the well-known simile ut pictura poesis --as is painting so is in poetry-- which in turn functions as the theoretical underpinning of ekphrasis, a rhetorical device through which one medium of art tries to describe the essence and form of another medium of art, with the purpose of enhancing the original work described. Spanish post-romantic poet and writer Gustavo Adolfo Bécquer (1836-1870) mastered this rhetorical strategy by expertly weaving all of his artistic interests into his prose. The purpose of this dissertation is to analyze how Bécquer makes his readers both see and hear through his prose. My semiotic research encompasses the various forms of ekphrasis used by Bécquer in the “Leyendas”. It shows how both images and symbols produce in readers sensory experiences that enhance their role as active participants in the creation of meaning. Thus, Bécquer´s prose is like a painting which not only tells a story, but also reflects reality through the eyes of the reader’s imagination. By using these ekphrastic strategies in his collection of short stories, Bécquer makes words, paintings, and music converge and collide with iconography, visual culture, and intertextuality. These components must be read, seen, heard, and understood to be more than just complementary to the text, but rather crucial elements, equal in importance to verbal expression. This analysis shows how Bécquer’s “Leyendas” not only tackle notions such as fantasy, figuration, and imagination, but also the importance of the reader´s gaze. Bécquer integrates processes such as imaginative action, iconization and visualization, into a semantic web whereby the reader creates his own particular hermeneutic image.

Semantic distributed database management with applications to the Internet dissemination of environmental data

The research presented in this dissertation is comprised of several parts which jointly attain the goal of Semantic Distributed Database Management with Applications to Internet Dissemination of Environmental Data. ^ Part of the research into more effective and efficient data management has been pursued through enhancements to the Semantic Binary Object-Oriented database (Sem-ODB) such as more effective load balancing techniques for the database engine, and the use of Sem-ODB as a tool for integrating structured and unstructured heterogeneous data sources. Another part of the research in data management has pursued methods for optimizing queries in distributed databases through the intelligent use of network bandwidth; this has applications in networks that provide varying levels of Quality of Service or throughput. ^ The application of the Semantic Binary database model as a tool for relational database modeling has also been pursued. This has resulted in database applications that are used by researchers at the Everglades National Park to store environmental data and to remotely-sensed imagery. ^ The areas of research described above have contributed to the creation TerraFly, which provides for the dissemination of geospatial data via the Internet. TerraFly research presented herein ranges from the development of TerraFly's back-end database and interfaces, through the features that are presented to the public (such as the ability to provide autopilot scripts and on-demand data about a point), to applications of TerraFly in the areas of hazard mitigation, recreation, and aviation. ^
