Durant la primera meitat del segle XX, el nivell de vida i les condicions de treball de molts sectors pagesos varen deteriorar-se. La imatge més contundent d'aquest deteriorament es troba en el contlicte que esclatà durant els anys trenta, a recés d'unes condicions polítiques oberturistes i esperonat per una depressió económica mundial

There is a body of literature that suggests that student self-assessment is a main goal in higher education (Boud et al., 1995; Tan, 2008); moreover new forms of work organization require a high level of skills and competences. The efforts to deal with competence gaps could be developed at many levels, such as employers, educational institutions, individuals and public agents. Employers could put into practice competence development programs to moderate these gaps. Educational institutions can restructure the curriculum to support students in attaining the competences that are essential in the labour market. Individuals themselves may deploy their resources (time and money) in general or specific competence training. Further, government agencies could fund competence promotion programs. Such challenges for education drive change in learning curricula and method, to properly include the competences required for developing global workers who can move beyond basic competence, to enhanced flexibility and adaptability. In performance assessment methods, there is a shift from the traditional exam-based assessments to more innovative task assessment, which considers performance in multiple different tasks carry out by students. ICTs make it technologically feasible to carry out a complete and complex selfassessment of competences, which provides immediate results to students or other recipients. In the case of students, the evaluation of competences is relevant as developing competences is part - if not all - of the objectives of education. Therefore, it is an important element of the quality of educational organizations (e.g., universities), and of their organizational success. Further, educational organizations may put special emphasis on some differentiating competences, which can be a means of positioning and differentiation from competitors. Competence assessment is an instrument to make students conscious of their strengths and weaknesses, leading to higher motivation to develop their own learning career

L’objectiu principal d’aquest projecte consisteix en realitzar l’estudi, l' anàlisi, el disseny, i el desenvolupament d’una aplicació que millori i faciliti la tasca d’un empleat que treballi fora de l’empresa. Es fa una anàlisi dels requeriments de l’aplicació, es fa el model d’anàlisi i tot seguit el model de disseny, i s’implementarà mitjançant les eines que utilitza la nostra empresa o les que millor s’adaptin a ella. S’analitza també el tipus i el volum d’informació que haurà de manejar. Durant el procés de cada una de les etapes de desenvolupament s’aniran realitzant les corresponents proves per, finalment, realitzar una posada en marxa sobre un empleat a mode de proves en un entorn real. Degut a la necessitat de mobilitat dels comercials s’utilitzen dispositius PDA (Personal Digital Assistant) per al desenvolupament de l’aplicació que els permetrà realitzar les seves tasques. En canvi, l’aplicació corporativa de gestió de l’empresa està situada en un servidor Windows, i per centralitzar i gestionar la informació de les PDA s’utilitzarà una aplicació sota el sistema Windows. L’aplicació s’haurà de confeccionar en funció de les dades que es vulgui que el comercial pugui consultar sobre un client, obra, ... Per millorar-ne la seva funcionalitat, es permetrà l’opció de multi-llenguatge. L’aplicació de la PDA tindrà a grans trets les següents funcionalitats: gestió de clients, gestió de contactes, consultar gestions comercials, consultar obres dels clients, consultar el planning i l’estat dels muntadors. Altres processos que haurà de permetre l’aplicació son: la configuració i instal·lació de l’aplicació en els dispositius PDA i la càrrega i el traspàs de les dades entre l’aplicació del PDA i l’aplicació corporativa de l’empresa

Este artículo tiene por finalidad analizar las medidas de adaptación al riesgo de inundación que se han realizado en el ámbito de la Costa Brava, con especial incidencia en el papel que han tenido las obras de infraestructura hidráulica en la prevención de avenidas. Se intenta comprobar hasta que punto la percepción local dominante sobre las obras hidráulicas como una de las formas más eficientes pera la prevención de inundaciones se contradice con las nuevas tendencias tanto en relación a los costes ecológicos de la construcción de estos dispositivos hidráulicos como al planeamiento urbanístico y fluvial, en general

Positioning a robot with respect to objects by using data provided by a camera is a well known technique called visual servoing. In order to perform a task, the object must exhibit visual features which can be extracted from different points of view. Then, visual servoing is object-dependent as it depends on the object appearance. Therefore, performing the positioning task is not possible in presence of nontextured objets or objets for which extracting visual features is too complex or too costly. This paper proposes a solution to tackle this limitation inherent to the current visual servoing techniques. Our proposal is based on the coded structured light approach as a reliable and fast way to solve the correspondence problem. In this case, a coded light pattern is projected providing robust visual features independently of the object appearance

This paper focuses on the problem of realizing a plane-to-plane virtual link between a camera attached to the end-effector of a robot and a planar object. In order to do the system independent to the object surface appearance, a structured light emitter is linked to the camera so that 4 laser pointers are projected onto the object. In a previous paper we showed that such a system has good performance and nice characteristics like partial decoupling near the desired state and robustness against misalignment of the emitter and the camera (J. Pages et al., 2004). However, no analytical results concerning the global asymptotic stability of the system were obtained due to the high complexity of the visual features utilized. In this work we present a better set of visual features which improves the properties of the features in (J. Pages et al., 2004) and for which it is possible to prove the global asymptotic stability

In this paper we face the problem of positioning a camera attached to the end-effector of a robotic manipulator so that it gets parallel to a planar object. Such problem has been treated for a long time in visual servoing. Our approach is based on linking to the camera several laser pointers so that its configuration is aimed to produce a suitable set of visual features. The aim of using structured light is not only for easing the image processing and to allow low-textured objects to be treated, but also for producing a control scheme with nice properties like decoupling, stability, well conditioning and good camera trajectory

Coded structured light is an optical technique based on active stereovision that obtains the shape of objects. One shot techniques are based on projecting a unique light pattern with an LCD projector so that grabbing an image with a camera, a large number of correspondences can be obtained. Then, a 3D reconstruction of the illuminated object can be recovered by means of triangulation. The most used strategy to encode one-shot patterns is based on De Bruijn sequences. In This work a new way to design patterns using this type of sequences is presented. The new coding strategy minimises the number of required colours and maximises both the resolution and the accuracy

Obtaining automatic 3D profile of objects is one of the most important issues in computer vision. With this information, a large number of applications become feasible: from visual inspection of industrial parts to 3D reconstruction of the environment for mobile robots. In order to achieve 3D data, range finders can be used. Coded structured light approach is one of the most widely used techniques to retrieve 3D information of an unknown surface. An overview of the existing techniques as well as a new classification of patterns for structured light sensors is presented. This kind of systems belong to the group of active triangulation method, which are based on projecting a light pattern and imaging the illuminated scene from one or more points of view. Since the patterns are coded, correspondences between points of the image(s) and points of the projected pattern can be easily found. Once correspondences are found, a classical triangulation strategy between camera(s) and projector device leads to the reconstruction of the surface. Advantages and constraints of the different patterns are discussed
