En aquest article es presenta el relat de les històries personals de deu joves geògrafs i geògrafes centrades en la seva formació acadèmica i en les respectives experiències i trajectòries en el món laboral. No pretén ser una mostra representativa de l’actual panorama professional al nostre país, sinó, tan sols, fer arribar al lector deu trajectòries individuals que tenen com a fil conductor l’intent d’assolir l’exercici professional i estable de la geografia

Ensenyar a participar és instruir els futurs professionals a viure amb una visió crítica sobre el món i a pensar en la feina de l’arquitecte no solament des del punt de vista de la tekne sinó també des del punt de vista ètic i moral: disciplina que ensenya les regles que han de dirigir l’activitat lliure de l’home. Des de l’inici del segle XX diversos autors amb diversos punts de vista sobre la pedagogia van assenyalar la importància d’aprendre a partir d’activitats (la tekne), aspecte que comporta la idea d’una major participació i coordinació (element ètic) de l’alumnat. De fet, l’adaptació de la Universitat espanyola a l’espai europeu d’ensenyament superior, segons el Conveni de Bolonya de 1999, no només significa un canvi tècnic pel que fa al càlcul dels crèdits i la seva distribució, sinó que comporta sobretot —i aquest és l’aspecte més interessant i suggeridor d’aquest procés— l’anomenat canvi cultural, en què tot el cos docent ha d’implicar-se per tal d’aplicar el nou model en el qual l’element ètic, que comporta un actitud critica i responsable, de l’ensenyament assumeix més protagonisme. Model que hauria d’estimular la implicació critica de l’alumnat i el desenvolupament cooperatiu d’un pensament científic elaborat des de l’autonomia personal

In the context of the round table the following topics related to image colour processing will be discussed: historical point of view. Studies of Aguilonius, Gerritsen, Newton and Maxwell. CIE standard (Commission International de lpsilaEclaraige). Colour models. RGB, HIS, etc. Colour segmentation based on HSI model. Industrial applications. Summary and discussion. At the end, video images showing the robustness of colour in front of B/W images will be presented

In image segmentation, clustering algorithms are very popular because they are intuitive and, some of them, easy to implement. For instance, the k-means is one of the most used in the literature, and many authors successfully compare their new proposal with the results achieved by the k-means. However, it is well known that clustering image segmentation has many problems. For instance, the number of regions of the image has to be known a priori, as well as different initial seed placement (initial clusters) could produce different segmentation results. Most of these algorithms could be slightly improved by considering the coordinates of the image as features in the clustering process (to take spatial region information into account). In this paper we propose a significant improvement of clustering algorithms for image segmentation. The method is qualitatively and quantitative evaluated over a set of synthetic and real images, and compared with classical clustering approaches. Results demonstrate the validity of this new approach

The automatic interpretation of conventional traffic signs is very complex and time consuming. The paper concerns an automatic warning system for driving assistance. It does not interpret the standard traffic signs on the roadside; the proposal is to incorporate into the existing signs another type of traffic sign whose information will be more easily interpreted by a processor. The type of information to be added is profuse and therefore the most important object is the robustness of the system. The basic proposal of this new philosophy is that the co-pilot system for automatic warning and driving assistance can interpret with greater ease the information contained in the new sign, whilst the human driver only has to interpret the "classic" sign. One of the codings that has been tested with good results and which seems to us easy to implement is that which has a rectangular shape and 4 vertical bars of different colours. The size of these signs is equivalent to the size of the conventional signs (approximately 0.4 m2). The colour information from the sign can be easily interpreted by the proposed processor and the interpretation is much easier and quicker than the information shown by the pictographs of the classic signs

This paper is focused on the robot mobile platform PRIM (platform robot information multimedia). This robot has been made in order to cover two main needs of our group, on one hand the need for a full open mobile robotic platform that is very useful in fulfilling the teaching and research activity of our school community, and on the other hand with the idea of introducing an ethical product which would be useful as mobile multimedia information point as a service tool. This paper introduces exactly how the system is made up and explains just what the philosophy is behind this work. The navigation strategies and sensor fusion, where machine vision system is the most important one, are oriented towards goal achievement and are the key to the behaviour of the robot

This paper presents the use of a mobile robot platform as an innovative educational tool in order to promote and integrate different curriculum knowledge. Hence, it is presented the acquired experience within a summer course named ldquoapplied mobile roboticsrdquo. The main aim of the course is to integrate different subjects as electronics, programming, architecture, perception systems, communications, control and trajectory planning by using the educational open mobile robot platform PRIM. The summer course is addressed to a wide range of student profiles. However, it is of special interests to the students of electrical and computer engineering around their final academic year. The summer course consists of the theoretical and laboratory sessions, related to the following topics: design & programming of electronic devices, modelling and control systems, trajectory planning and control, and computer vision systems. Therefore, the clues for achieving a renewed path of progress in robotics are the integration of several knowledgeable fields, such as computing, communications, and control sciences, in order to perform a higher level reasoning and use decision tools with strong theoretical base

In computer graphics, global illumination algorithms take into account not only the light that comes directly from the sources, but also the light interreflections. This kind of algorithms produce very realistic images, but at a high computational cost, especially when dealing with complex environments. Parallel computation has been successfully applied to such algorithms in order to make it possible to compute highly-realistic images in a reasonable time. We introduce here a speculation-based parallel solution for a global illumination algorithm in the context of radiosity, in which we have taken advantage of the hierarchical nature of such an algorithm

Els autors s’endinsen en aquest article en l’estudi de les relacions entre geografia, orientalisme i colonialisme a Europa al tombant del segle passat, tot introduint la perspectiva de gènere i en el marc d'un interès més general per la història del pensament geogràfic contemporani. Ho fan a partir de l’anàlisi contextualitzada d'un text de l’època que fa referència al cas espanyol i a la seva aventura colonial africana. Es tracta del llibre El Marroc sensual i fanàtic (1936) d’Aurora Bertrana, una versió molt elaborada del discurs de la diferència i una bona il•lustració de la literatura de viatges de dones europees, força excepcional i atípica -això sí- en el context literari català i espanyol de l’època
