Ophthalmic: Laboratorio virtual para el diseño de nuevas lentes oftálmicas multifocales
(Universitat Politècnica de València, 2013-06-02) Calatayud, Arnau; Remón, Laura; Monsoriu, Juan A.; Giménez, Fernado; Furlan, Walter D.; Ministerio de Ciencia e Innovación; Generalitat Valenciana; Universitat Politècnica de València
[EN] This work presents a new virtual laboratory, OPHTALMIC, developed with MATLAB GUI for using in Optics and Optometry courses as a computer tool for studying the focusing properties of multifocal diffractive both on unconventional structures both periodic and aperiodic. This virtual laboratory enables students to quickly and easily analyze the influence of the different parameters of construction and find the best solution for a user.
Círculos de Mohr: un laboratorio virtual para la enseñanza y el aprendizaje de estados tensionales planos

[EN] Linear elasticity is a discipline that studies the elastic solid under external forces that generate a mechanical response in linear elastic regime. In particular, it is of special interest to study the stresses and strains at any point of the solid, which is known as the elastic problem. Moreover, the problem of plane stress state -that is, in two dimensions- it is very common in engineering. Prior to its study, it is necessary to first obtain the so-called stress state in the differential vicinity around a point of the elastic solid, then calculating the different values that can reach the tensions at that point in any direction. This paper shows a virtual laboratory based on the graphical method called Mohr's Circle -attributed to engineer Otto Christian Mohr (1835-1918)- which allows to represent the stress state at a point from a user-defined set of variables. The virtual laboratory MOHR, implemented with the MATLAB package through its graphical user interface (GUI), allows full interactivity and can obtain the values of the stresses in any direction. This application is an excellent tool to support the teaching and learning process of mechanics-related subjects in engineering studies.
Analysis of Oscillations in a Cableway: Wind Load Effects
(Universitat Politècnica de València, 2013-06-02) Gustincic, Jan; Garcia-Raffi, Lluís M.; Universitat Politècnica de València
[EN] The purpose of this paper is to develop and investigate a non-linear model for analysing the reaction of a self-detachable cabin monocable ropeway exposed to a sudden deceleration and wind forces. The First and Second Newton's Law and Differential Equations are the basic tools for building the model. Furthermore a few basic considerations have been made about the air “dragging and lifting" forces that induce oscillations and vibrations in mechanical systems alike. All the numerical data used for the simulation was taken from a ropeway in the skiing site of Ravascletto-Zoncolan in the North- East of Italy.
Generación de fractales a partir del método de Newton
(Universitat Politècnica de València, 2013-06-02) Marín, María José; Giménez, Fernando; Monsoriu, Juan A.; Ministerio de Ciencia e Innovación; Universitat Politècnica de València; Generalitat Valenciana
[EN] A large number of fractals known, as Julia fractals and Mandelbrot, can be generated from an iterative method. In this paper we present a virtual laboratory developed as a Graphical User Interface (GUI) of Matlab that allows us to study and visualize in real time the relationship between Newton iterative methods of two variables and the generation of fractals. The main objective is to allow Technical School students in Numerical Computation subjects to acquire the skills to generate fractals and interpret their plots in terms of the convergence or divergence speed of the sequence of iterated.
Modelización no lineal de secciones aeronaúticas con EXCEL-SOLVER©

[EN] The program MICROSOFT-EXCEL© has a great popularity in the professional world of engineering-consulting. The authors are aware of that from own experience. This is the reason that has led us to implement a nonlienar model to predict the ultimate strenght of fuselage and wings structures. The didactic methology has been developed for the subject Aircraft Structural Design in the 4th course of Aeronautical Engineering studies at the Polythecnic University of Valencia. The students show a high level of satisfaction since they learn nonlinear computational methods, valid for real structures; they are capable of the implementation with help of the very visual and handle tool MICROSOFT-EXCEL© (without programming code) and finally they solve nonlinear optimization problems with the numerical analysis complement SOLVER ©.
