Risolvere problemi aritmetici. Test e training su comprensione, rappresentazione, categorizzazione, pianificazione e memoria.
2009
Un programma in CD-ROM per migliorare le competenze nel problem solving matematico e potenziare le abilità cognitive e i processi che sottostanno all’attività di soluzione dei problemi. Il programma si articola in due moduli. Il modulo di assessment consente di valutare le abilità di risoluzione dei problemi e di individuare i diversi profili di difficoltà che i bambini possono presentare. Il modulo di training propone numerosi problemi matematici a difficoltà crescente e varie attività di potenziamento delle abilità necessarie a risolvere i problemi, come la comprensione, la rappresentazione, la categorizzazione e la pianificazione. Particolare attenzione è dedicata ai processi cognitivi l…
Approcci statistici per processi produttivi
2020
Il testo presenta una rassegna di analisi e modelli lineari statistici applicati ai dati economici con riferimento agli aspetti della specificazione lineare, trattando anche i modelli classici di produttività ed efficienza e soffermandosi sull’analisi delle carte di controllo statistico.
Inverse procedural modeling of 3D models for virtual worlds
2016
This course presents a collection of state-of-the-art approaches for modeling and editing of 3D models for virtual worlds, simulations, and entertainment, in addition to real-world applications. The first contribution of this course is a coherent review of inverse procedural modeling (IPM) (i.e., proceduralization of provided 3D content). We describe different formulations of the problem as well as solutions based on those formulations. We show that although the IPM framework seems under-constrained, the state-of-the-art solutions actually use simple analogies to convert the problem into a set of fundamental computer science problems, which are then solved by corresponding algorithms or opt…
Objective evaluation of the width of source ensemble in virtual halls
2012
[EN] In this work, we study the effects of the width of the sound source in several acoustical virtual room models with different topologies, sizes and uses, calibrated with commercial software. To achieve this aim, a square distribution of sound sources with variable side length has been considered. We have auralized four channels of speech signal and musical signal in three different locations in each room. By using signal processing techniques, a comparison of multisource auralizations with the ones obtained from a single source in the middle of the stage is made. Also, the variations between the usual room parameters obtained from these simulations are analyzed, in order to show the eff…
Observer-based finite-time fuzzy H∞ control for discrete-time systems with stochastic jumps and time-delays
2014
This paper is concerned with the problem of observer-based finite-time H ∞ control for a family of discrete-time Markovian jump nonlinear systems with time-delays represented by Takagi-Sugeno (T-S) model. The main contribution of this paper is to design an observer-based finite-time H ∞ controller such that the resulting closed-loop system is stochastic finite-time bounded and satisfies a prescribed H ∞ disturbance attenuation level over the given finite-time interval. Sufficient criteria on stochastic finite-time H ∞ stabilization via observer-based fuzzy state feedback are presented for the solvability of the problem, which can be tackled by a feasibility problem in terms of linear matrix…
BioLab: An Educational Tool for Signal Processing Training in Biomedical Engineering
2007
This paper introduces and evaluates BioLab, a tool for teaching biosignal processing. BioLab has been used in the biomedical engineering module that is given in the second semester of the fifth year of the electronic engineering degree at the University of Valencia, Spain. This module and its correspondent curricular pathway are also reviewed. BioLab allows the results obtained with digital processing techniques to be shown interactively in the theory classes, and it also provides support in laboratory sessions. The graphic interface of BioLab simplifies its learning and use and provides access to processing and visualization functions by means of menus. The tool is based on Matlab since th…
Active learning in digital communications with low-cost software defined radio
2021
Las comunicaciones digitales se enseñan tradicionalmente en sesiones de laboratorio desde un punto de vista teórico, utilizando plataformas de simulación. Sin embargo, el sistema de Acreditación Académica incluye la dimensión de "lo que se espera que los estudiantes sean capaces de hacer", lo que plantea la necesidad de disminuir la brecha entre las sesiones de laboratorio simuladas y un enfoque más práctico y realista. En este trabajo, proponemos una metodología para mejorar el aprendizaje de los aspectos prácticos relacionados con los cursos de Comunicaciones Digitales, así como para aumentar la motivación de los estudiantes, mediante el uso de dispositivos de radio definida por software …
Eco-Phenomenology: Philosophical Sources and Main Concepts
2018
Eco-phenomenology is a new developing trend, but its roots can be traced to philosophia naturalis (life philosophy), the philosophies of Schelling, Nietzsche, Bergson, Husserl, Merleau-Ponty, and other philosophers. The ecological turn in phenomenology is prompted by authors dealing with the problems of the human being – nature, life, the Universe. Eco-phenomenology and eco-philosophy are different teachings, eco-phenomenology being more theoretically fundamental while eco-philosophy until now more politically oriented. Eco-phenomenology appeals to us to look “Back to the Earth itself,” but that it is not enough to solve the question of the nature of nature and to recognize the meaning of n…
Design and Validation of a FPGA-Based HIL Simulator for Minimum Losses Control of a PMSM
2021
This work examines the FPGA programmable logic platforms applied to minimum losses control of a Permanent Magnet Synchronous Motor (PMSM), which represents a flexible solution for the implementation of an advanced digital control algorithm, given their intrinsic parallel structure and the capability to be directly reprogrammable in the field. In particular, design and validation of a FPGA-based Hardware-In-the-Loop (HIL) simulator is proposed, by investigating about data format, quantization and discretization effects and other issues arising during the experimental validation of a controller prototype, in order to reduce the embedded software development cycle and test control systems. The…
Viejos paisajes, nuevas tecnologías: una reconstrucción del paisaje Holoceno con gvSIG y sextante
2010
Con el objetivo de reconstruir el paisaje geomorfológico de finales del cuaternario y comienzos del Holoceno, se ha utilizado gvSIG y sextante para intentar establecer el paisaje a partir de los datos de campoarquelógicos y geomorfológicos recogidos durante una veintena de años en la cuenca media y alta del río Serpis. La evolución cuaternaria es la historia de un vaciado (erosión + denudación) de los valles del curso alto y medio del Serpis, con algunas interrupciones (fases de sedimentación). Testigos de dicha evolución son las terrazas fluviales adscritas por nosotros a diversos periodos del Cuaternario. La combinación de métodos tradicionales y el trabajo con el uso de herramientas SIG …
