dcterms.abstract: Such as the author states in the first pages, this book is the result of several years of teaching the involved topics at the California Polytechnic State University (Cal Poly), San Luis Obispo, California, U.S.A, to undergraduates. This characteristic can be observed in the organization of the book, in each of the chapters, and in the hands-on orientation of each of the presented topics.\n\n<i>(Párrafo extraído del texto a modo de resumen)</i>

dcterms.abstract: This book makes a clear presentation of the traditional topics included in a course of undergraduate parallel programming. As explained by the authors, it was developed from their own experience in classrooms, introducing their students to parallel programming. It can be used almost directly to teach basic parallel programming.

dcterms.abstract: Resource allocation is a usual problem that must be faced during a distributed system design. Despite the large number of algorithms proposed in literature to solve this problem, most papers lack of detailed descriptions about how to turn these algorithms into real-world reliable protocols. This article presents a fault-tolerant algorithm for distributed resource allocation named SLOTS which is implemented as an executable protocol. It allocates resources among members in a fairly manner using simple heuristics and employing a donation approach. SLOTS supports the dynamic behavior of clusters and provides high availability services. It bases its fault-tolerance properties and membership changes in atomic sets of operations (like transactions) using services provided by an underlying Group Communication System.

dcterms.abstract: Handling faults is a growing concern in HPC; higher error rates, larger detection intervals and silent faults are expected in the future. It is projected that, in exascale systems, errors will occur several times a day, and they will propagate to generate errors that will range from process crashes to corrupted results because of undetected errors. In this article, we propose a methodology that improves system reliability against transient faults, when running parallel message-passing applications. The proposed solution, based on process replication, has the goal of helping programmers and users of parallel scientific applications to achieve reliable executions with correct results. This work presents a characterization of the strategy, defining its behavior in the presence of faults and modeling the temporal costs of employing it. As a result, we show its efficacy and viability to tolerate transient faults in HPC systems.

dcterms.abstract: Convolutional Neural Networks have been providing a performance boost in many areas in the last few years, but their performance for Handshape Recognition in the context of Sign Language Recognition has not been thoroughly studied. We evaluated several convolutional architectures in order to determine their applicability for this problem. Using the LSA16 and RWTH-PHOENIX-Weather handshape datasets, we performed experiments with the LeNet, VGG16, ResNet-34 and All Convolutional architectures, as well as Inception with normal training and via transfer learning, and compared them to the state of the art in these datasets. We included experiments with a feedforward neural network as a baseline. We also explored various preprocessing schemes to analyze their impact on the recognition. We determined that while all models perform reasonably well on both datasets (with performance similar to hand-engineered methods), VGG16 produced the best results, closely followed by the traditional LeNet architecture. Also, pre-segmenting the hands from the background provided a big boost to accuracy.

dcterms.abstract: El presente trabajo se enmarca en una investigación que se está llevando a cabo acerca de la utilización de Materiales Didácticos Hipermediales (MDH) para la enseñanza de la Matemática en la universidad. Se realizó un estudio de caso que implicó el diseño de un MDH y su implementación en un curso de Matemática dirigido a estudiantes de primer año de una Facultad de Ingeniería. Se indagó acerca de las variables que pueden incidir en que los estudiantes manifiesten una actitud negativa, positiva o indiferente y acerca de cuáles son las razones por las cuales valoran de uno u otro modo un MDH. En este trabajo, se presentan algunos de los resultados obtenidos en relación a las actitudes de los estudiantes frente al uso de este MDH. Como aporte de esta investigación se analizan los factores positivos y negativos encontrados a lo largo de la investigación que sirven como andamiaje para otros docentes del área.; This work is part of a research that has being carried out about the use of Hypermedia Materials for teaching Mathematics at the University. A case of study involving the design and implementation of a Hypermedia Material in a Mathematics course for freshmen of a School of Engineering was performed. Variables that can affect students’ attitude (negative, positive or indifferent) in relation to their experience with Hypermedia Material are analyzed. As a consequence, in this paper, some of the results obtained in relation to student attitudes towards the use of this Hypermedia Material are presented. Positive and negative factors found throughout this experience are detailed here, so it can serve as scaffolding for other teachers in the area.

dcterms.abstract: En este trabajo se relevan estudios que analizan la integración de tecnologías de información y comunicación (TIC) en la enseñanza y aprendizaje en instituciones de nivel superior. Se pone foco -entre otras variables- en la exploración de actitudes y percepciones de profesores/as y estudiantes. De acuerdo a esta motivación, en este artículo confluyen distintas investigaciones realizadas en diversos países, y cuya selección se efectúa a partir de una revisión bibliográfica sistemática. Las producciones científicas halladas abren reflexiones en torno a posiciones individuales e intersubjetivas respecto del uso de tecnologías digitales en la práctica educativa. Se discuten beneficios y problemáticas que se asocian a estas experiencias, acorde a posibilidades institucionales y habilidades que se ponen en juego para su dominio. Se expone una síntesis del estado del arte, destacándose recurrencias y divergencias entre las distintas publicaciones, y sistematizándose discusiones que podrían profundizarse en instancias futuras. Este análisis resulta en un aporte para los actores educativos que requieran contemplar aspectos influyentes frente a la utilización de las TIC en educación, y/o bien, deban definir acciones estratégicas al respecto. El conjunto de las problematizaciones tributa a la investigación/acción para el fortalecimiento de las prácticas educativas.; In this work, diverse studies analyzing the integration of information and communication technologies (ICT) in teaching and learning processes, in high education institutions, are reviewed. This paper focalizes on the analyses of different variables related with the attitudes and the perceptions of students and teachers using ICT in educational scenarios. According to this motivation, different previous researches carried out at different countries were selected, considering a methodological process of bibliographic systematic revision. The studies that have been reviewed open reflections on the use of digital technologies in educational scenarios, considering individual and interrelated variables. Not only advantages and disadvantages usually referred by the authors are discussed, but also the necessary skills and institutional barriers/possibilities are considered. A synthesis and an analysis of the state of the art related with this research topic are presented here, in which the similarities and differences among the authors involved are highlighted. These debates contribute to the research related with the improvement of educational practices.
