SIGFRUT: aplicación web para el diseño de plantaciones e instalaciones agrícolas

The SIGFRUT project is set within what we could call GIS applications in a web environment. (The acronym GIS is SIG in Spanish). We are all familiar with Internet map servers or IMS, with which we can visualize different thematic layers, check their attributes and, in the best cases, consult a data base, selecting and visualizing the elements that meet the required conditions. Nevertheless, these types of applications are basically simple map viewers and do not have any more functional features than the classic tools of visualization and consultation.(...)

Erasmus. Girona els ha canviat la vida

L’experiència Erasmus s’associa sovint a sortir de festa, estudiar poc i passar-s’ho tan bé com es pugui aprofitant que coneixes gent nova, que ets en un país estranger, que tens la família lluny i no et pot passar comptes, etc. Però aquests són només aspectes parcials, potser els més visibles, de tota l’experiència. Marxar de casa per estudiar en un país estranger comporta una sèrie de canvis en la vida que l’estudiant viu de manera més o menys intensa, i que poden marcar el seu futur. A aquests sis estudiants, Girona els ha canviat la vida. De fet el que els ha canviat la vida ha estat l’experiència Erasmus, i els hauria passat en qualsevol país on haguessin anat per motius d’estudi. Però ells van triar Girona. I Girona quedarà en el seu record per sempre. Nadeia Balsalobre, tècnica de l’Oficina de Relacions Exteriors ens explica els detalls en aquest reportatge

Viabilitat tècnica i econòmica de la implantació del mètode Ganimede® en un procés de vinificació

L’objecte del projecte és realitzar un estudi de viabilitat tècnica i econòmica respecte la implantació del mètode Ganimede® en el procés de vinificació enfront els sistemes convencionals. Aquest mètode es basa en la instal•lació dels dipòsits fermentadors patentats anomenats també Ganimede® que van néixer durant la verema 1997 de la mà de l’enòleg i inventor italià Francesco Marin

Adaption of Courses and Learning Environment to the User Context in dotLRN

The explosive growth of Internet during the last years has been reflected in the ever-increasing amount of the diversity and heterogeneity of user preferences, types and features of devices and access networks. Usually the heterogeneity in the context of the users which request Web contents is not taken into account by the servers that deliver them implying that these contents will not always suit their needs. In the particular case of e-learning platforms this issue is especially critical due to the fact that it puts at stake the knowledge acquired by their users. In the following paper we present a system that aims to provide the dotLRN e-learning platform with the capability to adapt to its users context. By integrating dotLRN with a multi-agent hypermedia system, online courses being undertaken by students as well as their learning environment are adapted in real time

Pose-based SLAM with probabilistic scan matching algorithm using a mechanical scanned imaging sonar

This paper proposes a pose-based algorithm to solve the full SLAM problem for an autonomous underwater vehicle (AUV), navigating in an unknown and possibly unstructured environment. The technique incorporate probabilistic scan matching with range scans gathered from a mechanical scanning imaging sonar (MSIS) and the robot dead-reckoning displacements estimated from a Doppler velocity log (DVL) and a motion reference unit (MRU). The proposed method utilizes two extended Kalman filters (EKF). The first, estimates the local path travelled by the robot while grabbing the scan as well as its uncertainty and provides position estimates for correcting the distortions that the vehicle motion produces in the acoustic images. The second is an augment state EKF that estimates and keeps the registered scans poses. The raw data from the sensors are processed and fused in-line. No priory structural information or initial pose are considered. The algorithm has been tested on an AUV guided along a 600 m path within a marina environment, showing the viability of the proposed approach

An overview of the advantages and constraints of coded pattern projection techniques for autonomous navigation

The absolute necessity of obtaining 3D information of structured and unknown environments in autonomous navigation reduce considerably the set of sensors that can be used. The necessity to know, at each time, the position of the mobile robot with respect to the scene is indispensable. Furthermore, this information must be obtained in the least computing time. Stereo vision is an attractive and widely used method, but, it is rather limited to make fast 3D surface maps, due to the correspondence problem. The spatial and temporal correspondence among images can be alleviated using a method based on structured light. This relationship can be directly found codifying the projected light; then each imaged region of the projected pattern carries the needed information to solve the correspondence problem. We present the most significant techniques, used in recent years, concerning the coded structured light method

Assaig de definició de l’àrea urbana de Girona

This article is an essay aiming at the definition of the urban district of Girona, having as a base the analysis of the intensities and directional tendencies of labour mobility fluxes in it. Several cathegories will be signaled inside this area which wil enable us to differenciate a number of crowns of municipalities according to their respective links with Girona town. A reflection set forth by Francesco Indovina on the concept of diffused town will be the first step in the attempt to typify this area. Thus, the existence of a diffused city core of which would be Girona town will be argued, an issue this one which is to be analysed in future studies
