One of the fundamental aspects in the adaptation of the teaching to the European higher education is changing based models of teacher education to models based on student learning. In this work we present an educational experience developed with the teaching method based on the case method, with a clearly multidisciplinary. The experience has been developed in the teaching of analysis and verification of safety rails. This is a multidisciplinary field that presents great difficulties during their teaching. The use of the case method has given good results in the competences achieved by students

The technique of reinforcement of wooden floors is a matter clearly multidisciplinary. The teaching of the subject using the "traditional" method, explaining the theory first and then proposing and solving problems has not been successful. This paper discusses the results of a teaching experiencie. It has been the teaching of the subject by the case method. The results are clearly superior to those obtained with the traditional methodology.

Effective automatic summarization usually requires simulating human reasoning such as abstraction or relevance reasoning. In this paper we describe a solution for this type of reasoning in the particular case of surveillance of the behavior of a dynamic system using sensor data. The paper first presents the approach describing the required type of knowledge with a possible representation. This includes knowledge about the system structure, behavior, interpretation and saliency. Then, the paper shows the inference algorithm to produce a summarization tree based on the exploitation of the physical characteristics of the system. The paper illustrates how the method is used in the context of automatic generation of summaries of behavior in an application for basin surveillance in the presence of river floods.

Reproducible research in scientic work ows is often addressed by tracking the provenance of the produced results. While this approach allows inspecting intermediate and nal results, improves understanding, and permits replaying a work ow execution, it does not ensure that the computational environment is available for subsequent executions to reproduce the experiment. In this work, we propose describing the resources involved in the execution of an experiment using a set of semantic vocabularies, so as to conserve the computational environment. We dene a process for documenting the work ow application, management system, and their dependencies based on 4 domain ontologies. We then conduct an experimental evaluation sing a real work ow application on an academic and a public Cloud platform. Results show that our approach can reproduce an equivalent execution environment of a predened virtual machine image on both computing platforms.

Hoy en día, los sistemas middleware de publicar-suscribir con la filtración de mensajes basado en contenido tiende a ser popularizado, y un sistema como este requiere codificar su mensaje a la combinación de varios elementos que se encuentran en los conjuntos no-interseccionados. Varios predicados posibles en los dominios de esos conjuntos forman un filtro, y el núcleo de algoritmo filtrado es seleccionar filtros adaptados tan pronto como sea posible. Sin embargo, el conjunto, que está formado por los filtros, contiene la extremadamente fuerte indeterminación y distensibilidad, lo que restringe el algoritmo filtrado. Por la resolución de la distensibilidad, se estudió la característica del conjunto de filtros en álgebra, y sabía que es un retículo específico. Por lo tanto, se intenta usar el carácter, el cual los retículos forman un conjunto parcialmente ordenado (o poset, del inglés partially ordered set) con límites, para reducir el tamaño de conjunto de filtros (compresión equivalente). Por estas razones, es necesario implementar un contenedor abstracto de retículo, y evaluar su desempeño tanto en la teoría, como en la práctica, para la solución de la distensibilidad del conjunto de filtros. Retículo (Lattice) es una estructura importante de Álgebra Abstracta, comúnmente se utiliza para resolver el problema teórico, y apenas de ser un contenedor abstracto en la ciencia de software, como resultado de su implementación compleja que proviene de su trivialidad en álgebra. Y por eso se hace difícil mi trabajo. Con el fin de evitar la teoría compleja del sistema práctico, simplemente introduce su núcleo algoritmo, el algoritmo de conteo, y esto llevó a cabo con el problema - la distensibilidad del conjunto de filtros. A continuación, se investigó la solución posible con retículos en la teoría, y se obtuvo el diseño de la implementación, normas para las pruebas xUnit y par´ametros para la evaluación. Por último, señalamos el entorno, el resultado, el análisis y la conclusión de la prueba de rendimiento.

Reproducible research in scientific workflows is often addressed by tracking the provenance of the produced results. While this approach allows inspecting intermediate and final results, improves understanding, and permits replaying a workflow execution, it does not ensure that the computational environment is available for subsequent executions to reproduce the experiment. In this work, we propose describing the resources involved in the execution of an experiment using a set of semantic vocabularies, so as to conserve the computational environment. We define a process for documenting the workflow application, management system, and their dependencies based on 4 domain ontologies. We then conduct an experimental evaluation using a real workflow application on an academic and a public Cloud platform. Results show that our approach can reproduce an equivalent execution environment of a predefined virtual machine image on both computing platforms.
