El GREP (grup de recerca de producte, procs i producci) de la UdG actualment disposa duna eina informtica desenvolupada en un PFC del 2003 que li permet fer la seqenciaci de la producci dun taller mecnic amb un mxim de cinc productes, un nombre definit de possibles rutes de fabricaci per a cada producte i tres mquines. Aquesta eina s molt resolutiva per a aquests casos, ja que estudia totes les possibilitats i les comprova una per una. No obstant aquest fet presenta una srie de limitacions com sn el temps dexecuci doncs al comprovar totes les seqncies t un elevat cost computacional i la rigidesa del sistema doncs no ens permet seqenciar ms productes ni ms mquines. Per tal de donar soluci a aquest problema es planteja generar una nova eina informtica a partir de lactual per que permeti seqenciar ms peces sense ocupar tanta memria per aix implementar-hi futures millores com el temps de preparaci etc... Per a desenvolupar leina informtica shan utilitzat mtodes heurstics, concretament dos que sn: algoritmes gentics i cerca TABU. Aquests mtodes destaquen perqu no busquen totes les combinacions possibles sin que estudien una srie de combinacions i utilitzant mtodes de creuament i generaci dentorns busquen una soluci

El grup de visi per computadora de la Universitat de Girona, disposava dun manipulador lineal com a sistema de posicionament, per poder inspeccionar mitjanant visi artificial, la superfcie de diverses peces. El control es realitzava a partir dun PLC, controlant la posici de la plataforma de posicionament a partir dun servomotor, un servocontrolador i una targeta dentrada i sortida de polsos. Es pretn la recuperaci daquest sistema de posicionament lineal a partir de la recopilaci de la informaci inicial. El nou s ser enfocat al posicionament i a la classificaci de diversos elements. Daquesta forma es podr estudiar el funcionament dun servomotor governat per un servodriver i una targeta dentrada i sortida de polsos i sutilitzar com a element didctic per a la universitat. Es complementar la documentaci disponible i selaborar informaci tcnica

Molt sovint, a lindstria de lalimentaci o de la cosmtica, hi ha promocions on safegeixen productes de regal; aquests els embalen amb un sleever (tipus de plstic fora rgid) que desprs retractilen. Aquestes promocions solen ser espordiques i canviants i aix fa que no sigui factible la modificaci de la lnia de producci general per a realitzar-les. Per aquest motiu, moltes empreses disposen duna petita mquina de tall rotatiu per a poder tallar els sleevers ells mateixos, i aix tallar a molta velocitat i precisi aquestes petites produccions. Aix doncs, esdev molt interessant ladquisici daquest tipus de maquinria. Lobjectiu del projecte s fer lautomatitzaci duna mquina que pugui tallar aquest tipus de material rpidament per fer-lo rentable

We propose a probabilistic object classifier for outdoor scene analysis as a first step in solving the problem of scene context generation. The method begins with a top-down control, which uses the previously learned models (appearance and absolute location) to obtain an initial pixel-level classification. This information provides us the core of objects, which is used to acquire a more accurate object model. Therefore, their growing by specific active regions allows us to obtain an accurate recognition of known regions. Next, a stage of general segmentation provides the segmentation of unknown regions by a bottom-strategy. Finally, the last stage tries to perform a region fusion of known and unknown segmented objects. The result is both a segmentation of the image and a recognition of each segment as a given object class or as an unknown segmented object. Furthermore, experimental results are shown and evaluated to prove the validity of our proposal

This paper presents a vision-based localization approach for an underwater robot in a structured environment. The system is based on a coded pattern placed on the bottom of a water tank and an onboard down looking camera. Main features are, absolute and map-based localization, landmark detection and tracking, and real-time computation (12.5 Hz). The proposed system provides three-dimensional position and orientation of the vehicle along with its velocity. Accuracy of the drift-free estimates is very high, allowing them to be used as feedback measures of a velocity-based low-level controller. The paper details the localization algorithm, by showing some graphical results, and the accuracy of the system

Mosaics have been commonly used as visual maps for undersea exploration and navigation. The position and orientation of an underwater vehicle can be calculated by integrating the apparent motion of the images which form the mosaic. A feature-based mosaicking method is proposed in this paper. The creation of the mosaic is accomplished in four stages: feature selection and matching, detection of points describing the dominant motion, homography computation and mosaic construction. In this work we demonstrate that the use of color and textures as discriminative properties of the image can improve, to a large extent, the accuracy of the constructed mosaic. The system is able to provide 3D metric information concerning the vehicle motion using the knowledge of the intrinsic parameters of the camera while integrating the measurements of an ultrasonic sensor. The experimental results of real images have been tested on the GARBI underwater vehicle

This paper describes the improvements achieved in our mosaicking system to assist unmanned underwater vehicle navigation. A major advance has been attained in the processing of images of the ocean floor when light absorption effects are evident. Due to the absorption of natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination for processing underwater images. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion. In this paper a technique to correct non-uniform lighting is proposed. The acquired frames are compensated through a point-by-point division of the image by an estimation of the illumination field. Then, the gray-levels of the obtained image remapped to enhance image contrast. Experiments with real images are presented

Addresses the problem of estimating the motion of an autonomous underwater vehicle (AUV), while it constructs a visual map ("mosaic" image) of the ocean floor. The vehicle is equipped with a down-looking camera which is used to compute its motion with respect to the seafloor. As the mosaic increases in size, a systematic bias is introduced in the alignment of the images which form the mosaic. Therefore, this accumulative error produces a drift in the estimation of the position of the vehicle. When the arbitrary trajectory of the AUV crosses over itself, it is possible to reduce this propagation of image alignment errors within the mosaic. A Kalman filter with augmented state is proposed to optimally estimate both the visual map and the vehicle position

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
