Las Camelias de Amelia
No full textLa Camelias de Amelia (written in Spanish) is a 2009 collection of short stories about Puerto Rico and its people. Its author, Zoé Jiménez Corretjer, forms part of the Puerto Rican writers called ‘La Generación de los 80’ (authors writing in Spanish from the island and not in English from US territory.) This review only analyzes the work as a unit; those so inclined can read its twenty-five short stories by themselves. Las Camelias de Amelia is a very finely crafted piece of work
Discovering Puerto Rican Art Song: A Research Project on Four Art Song Works by Héctor Campos Parsi
No full textabstract: Puerto Rico has produced many important composers who have contributed to the musical culture of the nation during the last 200 years. However, a considerable amount of their music has proven to be difficult to access and may contain numerous errors. This research project intends to contribute to the accessibility of such music and to encourage similar studies of Puerto Rican music. This study focuses on the music of Héctor Campos Parsi (1922-1998), one of the most prominent composers of the 20th century in Puerto Rico. After an overview of the historical background of music on the island and the biography of the composer, four works from his art song repertoire are given for detailed examination. A product of this study is the first corrected edition of his cycles Canciones de Cielo y Agua, Tres Poemas de Corretjer, Los Paréntesis, and the song Majestad Negra. These compositions date from 1947 to 1959, and reflect both the European and nationalistic writing styles of the composer during this time. Data for these corrections have been obtained from the composer's manuscripts, published and unpublished editions, and published recordings. The corrected scores are ready for publication and a compact disc of this repertoire, performed by soprano Melliangee Pérez and the author, has been recorded to bring to life these revisions. Despite the best intentions of the author, the various copyright issues have yet to be resolved. It is hoped that this document will provide the foundation for a resolution and that these important works will be available for public performance and study in the near future.Dissertation/ThesisD.M.A. Music 201
Configuration and Representation of Large-Scale Dataflow Graphs using the Dataflow Interchange Format

No full textAbstract—A wide variety of DSP design tools have been developed that incorporate dataflow graph representations into their GUI-based design environments. However, as the complexity of application graph topologies increases, textual manipulation of graph specifications becomes increasingly important. The dataflow interchange format (DIF) provides a text-based language for the description of dataflow graphs. Currently, the DIF infrastructure supports the specification of mixed-grain dataflow models, porting of dataflow applications specified in DIF across DSP design tools, software synthesis of applications specified in DIF, as well as a variety of optimization and analysis capabilities. This paper presents a novel set of dataflow graph configuration features that have been developed in the DIF language. These features greatly enhance the flexibility and power with which dataflow graphs, especially large-scale graphs, can be constructed and manipulated in DIF. To support the new graph configuration capabilities, several new concepts have been incorporated into the DIF language semantics, such as the capability to handle certain dynamic dataflow constructs, and support for C-like arrays in DIF specifications. Along with these concepts, a new framework for the construction and manipulation of DIF objects through the use of C/C++ is presented, and applications of this framework are demonstrated

The dataflow interchange format (DIF) is a standard language for specifying mixed-grain dataflow models for digital signal processing (DSP) systems and other streaming-related application domains. Here, by DSP, we mean applications that processes digitally represented signals, includin
