TL;DR: Two new dynamic models are developed, the first of which is based on the Singular Value Decomposition (SVD), while the second comprises two consecutive steps: elimination of less contributive parameters and application of a SVD method.
Abstract: This work presents the identification of dynamic parameters in automotive vehicles. In order to develop the identification problem, a dynamic model is obtained for the front suspension of a race car. Two new dynamic models are developed, the first of which is based on the Singular Value Decomposition (SVD), while the second comprises two consecutive steps: elimination of less contributive parameters and application of a SVD method. Finally, both models are analyzed and validated by means of data cross-referencing for new trajectories other than those used during the identification process. The model obtained using the elimination reproduces the dynamic behavior with very good approximation even with the inclusion of errors, so it is presented as the most viable methodology for obtaining base parameters.

TL;DR: In this paper, the authors describe the forma en which la asignatura Electronica de Potencia, as assignatura troncal correspondiente al titulo Ingeniero Tecnico Industrial especialidad en ElectronICA Industrial, ha been modificada for adecuacion al nuevo sistema europeo de transferencia de creditos (ECTS).
Abstract: En el presente articulo se describe la forma en que la asignatura Electronica de Potencia, asignatura troncal correspondiente al titulo Ingeniero Tecnico Industrial especialidad en Electronica Industrial, ha sido modificada para su adecuacion al nuevo sistema europeo de transferencia de creditos (ECTS). Se presenta los contenidos teoricos y practicos, la planificacion horaria y el sistema de evaluacion original, para a continuacion describir cuales eran los objetivos a alcanzar marcados por ECTS y cual ha sido la actuacion realizada para llegar a satisfacerlos intentando mantener las mismas cargas lectivas y docentes para alumnos y profesores respectivamente. El articulo no pretende ser ningun manual de referencia para la implantacion de ECTS en asignaturas, sino mas bien se desea reflejar la experiencia llevada a cabo por los profesores de la asignatura para adaptarla a este nuevo sistema.

TL;DR: In this paper, the potential of Lumbricus terrestris in early detection of earthquakes was evaluated using a comprehensive review of literature, which allowed an approach to state of the art the object of study.
Abstract: Iberoamerican in the course of history has been part of the largest earthquakes that have occurred on the planet. Just mention on the side of the peninsula, the Lisbon earthquake occurred in the year 1755. On the side of Latin America, the earthquake in Chile occurred in 2010. These events and occurred in the rest of the world have awakened the interest of the scientific community in the context of developing prevention or prediction models. Earthquakes according to the theory of elastic fracture can be anticipated; early detection of these phenomena is possible due to the accumulated internal energy that is released in the form of seismic waves received by earthquake-receptor species as Lumbricus terrestris Linnaeus. In this logic, it is proposed to assess the potential of this species earthquake-receptor in early detection of earthquakes. Methodologically, the study used a comprehensive review of literature, which allowed an approach to state of the art the object of study. It is concluded that indeed L. terrestres is a species able to anticipate earthquakes.

TL;DR: In this article, different wind wave spectrum representations for shallow water are compared from a parametric point of view, including formulations with both constant (TMA and FRF spectra) and variable (Wallops-SW and GLERL spectras) frequency exponents, showing the necessity of at least four parameters in order to achieve an adequate representation of the full range of the spectrum in non-saturated or decaying seas propagating in shallow water.
Abstract: Different wind wave spectrum representations for shallow water are compared from a parametric point of view, including formulations with both constant (TMA and FRF spectra) and variable (Wallops-SW and GLERL spectra) frequency exponents. The results of the research clearly show the necessity of at least four parameters in order to achieve an adequate representation of the full range of the spectrum in non-saturated or decaying seas propagating in shallow water. Furthermore, when the modelling of the high frequency range is not of special interest, the total number of independent parameters could be reduced to only three without considerable loss of accuracy. Comparisons of theoretical shallow water spectral forms with spectra calculated from actual field measurements do not show any definite tendency in performance, being possible to obtain good results with any of the studied spectra. So, the selection of which spectrum to use in a particular application is still a quite subjective decision, being of importance the availability of input parameters needed for each model.

TL;DR: This article present a metodologia docente that integra satisfactoriamente the leccion magistral, the problemas de aula, las practicas de laboratorio, la evaluacion, and el trabajo del alumno fuera del horario lectivo.
Abstract: Este articulo presenta una metodologia docente que integra satisfactoriamente la leccion magistral, los problemas de aula, las practicas de laboratorio, la evaluacion y el trabajo del alumno fuera del horario lectivo. La leccion magistral, los problemas de aula y las practicas de laboratorio se plantean proponiendo al alumno un proyecto informatico real simplificado al inicio del curso cuya resolucion es el hilo conductor de toda la docencia. La evaluacion de la asignatura esta formada por pruebas distintas en las que cabe destacar el "miniproyecto", un trabajo en grupo que obliga a poner en practica las aptitudes deseadas. EL "miniproyecto" implica, ademas, poder orientar el aprendizaje del alumno fuera del horario lectivo. Para conseguirlo ha sido necesario desarrollar un simulador de sistemas de adquisicion de datos que pueden emplear los alumnos en sus casas para desarrollar el trabajo y afianzar los conocimientos
