Actividades para fomentar las competencias transversales relacionadas con el razonamiento científico-técnico

Este artículo describe dos actividades que los autores llevan a cabo desde hace unos años en asignaturas de los últimos cursos de ingeniería y del máster de investigación que imparten. Estas actividades tienen por objetivo desarrollar competencias transversales tales como el razonamiento crítico, la capacidad de análisis y comprensión de trabajos científicos, y la argumentación y debate de opiniones contrapuestas, y están encaminadas a fomentar el razonamiento científico- técnico de los estudiantes. En concreto las actividades a las que nos referimos son de dos tipos, 1) sesiones de debate de artículos científico-técnicos y 2) preparación de preguntas tipo para examen. En el artículo se describen con detalle cómo se materializan estas dos actividades, y se realiza una evaluación cualitativa y cuantitativa del resultado de la experiencia, que nos permite concluir que contribuyen decisivamente a la formación de los estudiantes en las competencias transversales arriba mencionadas y, por lo tanto a mejorar el proceso de aprendizaje en general.SUMMARY -- This article describes two activities that the authors are carrying out since a few years ago in the latest courses of the engineering degree and masters they are teaching. These activities aim to develop generic skills such as critical thinking, the ability of analysis and understanding of scientific work, and the argumentation and discussion of opposing views. All of them are aimed at encouraging scientific and technical reasoning of students. These activities are the discussion/debate sessions of scientific-technical papers and the preparation of exam-like questions. The paper describes in detail how these two activities have been materialized and a qualitative and quantitative evaluation is provided. Out of this evaluation, the usefulness of these activities can be validated, and it can be concluded that they strongly contribute to the training of students in the transversal competences focus of this work and, as a consequence to improve the learning process

Diseño e implementación de herramientas Grid basadas en WSRF

El objetivo de este proyecto ha sido el desarrollo de una aplicación que permitiese acceder al middleware de Glosbus. Este software debe servir de puente entre el middleware y GridWay, que es una aplicación diseñada para obtener mejor rendimiento al enviar trabajos a un conjunto de recursos grid dinámicos. El motivo para implementar esta aplicación es la nueva implementación de C del toolkit lanzada el 30 de abril de 2005. Antes de comenzar a hablar de la aplicación hay que introducir al lector a toda una serie de conceptos sobre computación grid, Web Services y globus. Algunos ejemplos son XML, mensajes SOAP, OGSA, Stateful Web Services, WSRF,... [ABSTRACT] The objetive of this project has bee the development of an application to access Globus middleware. This application must be the bridge between the middleware and GridWay, an application designed to obtain the best performance from a set of dynamic grid resources. The motivation to do this,it's the brand nes C implementation of the toolkit that Globus released on April 30 2005. Before we start with this subject, we have to introduce the reader to all the new concept around grid computing, Web Services and Globus. Some of them are XLM, SOAP messages, OGSA, stateful Web Services,WSRF,..

Analysis of the threshold between GPON and EP2P

New services like Video on demand, Television (IPTV), high speed Internet access and Voice over IP on top the same link are called Triple Play services. These services demand very high bandwidth to customers. ADSL and ADLS2+ aren’t enough for supporting the new bandwidth requirement. One suitable solution for high bandwidth demand with a long reach is to use optical cable to customers (FTTX). Nowadays there are two technologies GPON (Gigabit passive optical network) and EP2P (Ethernet point-to-point) fighting for to be implemented in network access. This paper makes an evaluation between both solutions and it tries to answer the next question: What is the best solution for supporting requirement of Triple Play applications?Preprin

Who shot optical packet switching?

Looking at the volume of publications dealing with Optical Packet (OPS) and those dealing with Elastic Optical Networking (EON) in the period from 2000 to 2016, one clearly can observe that between 2004 and 2009 there is a boom of the OPS publications and then they start to diminish. At the same time, EON publications start to take-off (around 2011) and is steadily growing. EON is an emerging technology that may be considered as a killer technology in the sense that its performance, flexibility, associated cost, ease of deployment and marketing seem to be displacing OPS from the optical networking arena. The purpose of this paper is discuss if, effectively, EON is the killer technology of OPS. So then, besides review the EON technology, the paper analyzes its actual deployment possibilities.Peer ReviewedPostprint (author's final draft

Equacions de Maxwell en termes de formes diferencials

Treballs Finals de Grau de Matemàtiques, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2017, Director: Ignasi Mundet i Riera[en] Maxwell’s equations are one of the cornestones of physics. In this essay, we describe how these equations can be expressed in terms of differential forms. For this purpose, we present some results on smooth, riemannian and pseudo-riemannian manifolds in order to make this reformulation easier to understand

Verification of performance degradation in a telecommunications system due to the uncertainty of human users in the loop

The intensive use of new technologies that cause more interactions between systems and the daily activities of human users is changing the focus on how network re- sources should be managed. However, these changes can create challenges related to the level of uncertainty that people introduce to the system. In this context, this research study seeks to determine whether people’s uncertainty influences network performance and how significant its impact is. For these purposes, a simulated case study of a Vehicle for Hire application designed to run over a network slicing of a fifth-generation (5G) network. The simulations compared call drop rates in several settings configured to represent different levels of uncertainty, introducing random alterations to free channel planning reserved for the handover process. The simulation results reveal that the uncertainty specifically introduced by people exerts a high negative impact on network performance, evidencing the need to develop an algorithm that considers this uncertainty when managing resources within the 5G network core.This work has been supported by the Spanish Government through project TRAINER-A (PID2020-118011GB-C21) with FEDER contribution. Moreover, it has been supported by the Spanish Thematic Network under contract RED2018-102585-T (Go2Edge) and by the aid granted by the Sinfoni project INV2733 of the Cooperative University of Colombia.Peer ReviewedPostprint (published version
