  1. WAVEFRONT TESTER: Un nuevo laboratorio virtual para el estudio de los sensores frente de onda.

    Ferrando Martín, Vicente; Remón Martín, Laura; Furlan, Walter D.; Gimenez Palomares, Fernando; Monsoriu, Juan A.
    [EN] We present a new virtual laboratory developed with MatlabcGUI (Graphical User Interface) used toteach di erent aberration eff ects in the "Tecnologi a de Sensores Optoelectr onicos" at "Escuela T ecnicaSuperior de Ingenier a del Diseño" of the Universitat Polit ecnica de Val encia. The objective of this lab is to provide a computer tool to study the working principle of a Shack Hartman sensor and the parameters that determine the dynamic range of the same. Some examples made with di fferent aberrations (defocus,astigmatism, coma) and for diff erent sensor con gurations are presented.

  2. Rescate de la magnitud tiempo en el proceso de enseñanza-aprendizaje de las Turbomáquinas Hidráulicas

    Vicens Moltó, José Luis; Zamora Parra, Blas
    [EN] The behavior of a Hydraulic Turbomachine includes several coupled processes, which are in general not instantaneous, and require speci c periods of time for achieving their final status. Since a relevant quantity of Engineering students shows a trend towards the two-dimensionality, avoiding the transient evolutions,a teaching approach to the learning of transient processes is proposed in this work. Di erent hydraulic characteristic times, which linking to the control and dynamic simulation of the turbomachine performance, are identi ed and calculated. The purpose is to facilitate that the student was able to signi cantlylearn, with metacognitive capacity, the operation and...

  3. Modelos matemáticos en un problema de epidemias

    Vidal Meló, Anna; Boigues Planes, Francisco José; Estruch Fuster, Vicente Domingo
    [EN] The introduction of mathematical concepts through the development and the study of models have been addressed in several studies. The introduction of these models is usually done from the professor's speech and the student work is normally reduced to the experimentation with the given model. The IBM (Individual Based Model) approach to a problem is more understandable for the student, provides justi cationand can complement other approaches to the solution (di erential-continuous and/or discrete models). In this paper a teaching experience is presented, which tackles the same problem by means of complementary approaches on a continuous, discrete and IBM...

  4. Modelado y simulación de la cadena de suministro con AnyLogic®

    [ES] En este artículo se presenta una herramienta de software AnyLogic, para el modelado y simulación de la Cadena de Suministro (CS) proporcionando ayuda a la toma de decisiones a través de la simulación de escenarios de un mismo modelo de CS. AnyLogic da soporte a las metodologías de simulación más conocidas: sistemas de eventos discretos, dinámica de sistemas y modelado de agentes. Este artículo se centra en el contexto de dinámica de sistemas permitiendo la simulación de dos tipos de CS: colaborativa y no-colaborativa. Finalmente, se presenta un ejemplo ilustrativo en AnyLogic que permite comparar los dos modelos de...

  5. La innovación en la enseñanza de la Geometría Descriptiva. El uso de las herramientas digitales y el estudio de casos reales

    Cisneros Vivó, Juan José; Cabezos Bernal, Pedro Manuel
    [EN] Using computer in graphical expression teaching is being generalized in most of Architecture Schools.The subject of this paper is to show our experience in adapting traditional methodologies and contents tothe new three-dimensional drawing environment provided by CAD software. We pay much attention to the selection of those exercises that students must undertake. Every year we prepare a set of di erent architectural case studies containing di erent surfaces to be analyzed that are away from those abstract traditional exercises whose practical sense and application are not perceived by the student. Spatial resolution of problems and geometrical analysis of surfaces...

  6. Implantación de metodologías de cálculo a través del lenguaje Python para asignaturas impartidas en las titulaciones de la ETSIN.

    González Gutiérrez, Leo Miguel; Cercós Pita, Jose Luis; Esteban Burgos, Daniel
    [EN] The global target of this project is to improve the e ficiency of the students learning results by incorporating active learning methodologies such as the Python programming language which will improve theinterdisciplinarity and both horizontal and vertical academic coordination. We are also developing a complete repository, educational resources, and online videos in order to make the interaction and self-learning easier

  7. Hacia un nuevo entorno de aprendizaje en la Electrónica de Potencia: de lo virtual a lo personal

    Trujillo Aguilera, Francisco David; Pozo, A; Sotorrío, P. J.; Sánchez, F. J.; Blázquez, E. B.; Sánchez, J.
    [EN] Nowadays, the European Higher Education Area means an important change in the teaching/learning process: it is necessary to involve more re ciently to the students as well as to promote their independenceand active participation. This new framework includes the increase in the development and use of NewInformation and Communication Technology in education and the analysis of the academic performance of students. In this paper, it is described the implementation and development of a new learning environmentfor Power Electronics. To evaluate the bene fits and drawbacks of this new environment and the compliance with the objectives, several surveys have been...

  8. Docencia presencial y laboratorio remoto: una unión idónea para las prácticas de motores alternativos

    Navarro Arévalo, Emilio; Tizón Pulido, Juan Manuel
    [EN] It has been used in the same class time: a lecture and a remote laboratory for reciprocating engine prac-tices. In both cases, we have made use of video cameras to visualize real-time facilities. The lecture has been used to describe the test bench and the remote laboratory has been used to measure performances ofa spark ignition engine. This methodology is intended to solve the problem of overcrowding of students in the labs, mainly when the number of jobs for them is very low

  9. Diseño e implementación de tareas de modelización con iPad®'s: un enfoque dual

    Diago Nebot, Pascual David; Ortega Pons, Miriam; Puig Espinosa, Luis; Ferrando Palomares, Irene
    [ES] En este trabajo presentamos el diseño de dos propuestas para introducir la modelización de fenómenos físicos a través de actividades de modelización asistidas mediante iPad's. Cada una de las propuestas que vamos a presentar tiene una visión de la modelización: en un caso se trata de utilizar la modelización como vehículo para introducir contenidos matemáticos concretos mientras que, en el otro, pretendemos desarrollar una actividad que ayude a los alumnos a poner en marcha la competencia en resolución de problemas a través de la modelización. El objetivo es proporcionar dos propuestas basadas en la modelización dando detalles suficientes para...

    [EN] In this paper we present the qualitative analysis of the modelling process ofa 15-16 years old students teams working in a statistics activity with real data. We identify the di erent phases of the modelling process using the modelling cycle proposed by (Blum, Leiss, 2007) and we discuss the results from the perspective of the di culties founded during the analysis and the complexity of the modelling process analyze

  12. Coloreando el Álgebra Lineal

    Murillo Arcila, Marina; Beltrán Meneu, María José
    [EN] We present an example of how we can introduce basic concepts on Linear Algebra in a first course of an Engineering School. We use the RGB pattern color which allows us to decompose a color into three primary colors (namely, red, green, blue). By using this model we give a natural connexion between the additivity of the color decomposition and the notions on linear algebra (as vector space, linear combination and convex linear span of vectors). To visualize these connexions we use Geogebra.
