THE CHANGING ECONOMIC SPATIAL STRUCTURE OF EUROPE
Many theoretical and practical works aim at describing the spatial structure of Europe, where spatial relations have undergone continuous change. This article gives an overview of models describing the spatial structure of Europe. Their diversity is highlighted by listing of these models, without any claim to completeness. Our study aims at describing the economic spatial structure of Europe with bi-dimensional regression analysis based on the gravitational model. With the help of the gravity model, we get a spatial image of the spatial structure of Europe. With these images, we can justify the appropriateness of the models based on different methodological backgrounds by comparing them with our results. Our goal is not to create and show a new model that overwrites the existing ones, but rather to contribute to understanding the European spatial structure through a new methodological approach
Mobile Robot Localization using Panoramic Vision and Combinations of Feature Region Detectors
IEEE International Conference on Robotics and Automation (ICRA 2008, Pasadena, California, May 19-23, 2008), pp. 538-543.This paper presents a vision-based approach for
mobile robot localization. The environmental model is topological. The new approach uses a constellation of different types of affine covariant regions to characterize a place. This type of representation permits a reliable and distinctive environment modeling. The performance of the proposed approach is evaluated using a database of panoramic images from different rooms. Additionally, we compare different combinations of complementary feature region detectors to find the one that achieves the best results. Our experimental results show promising results for this new localization method. Additionally, similarly to what happens with single detectors, different combinations exhibit different strengths and weaknesses depending on the situation, suggesting that a context-aware method to combine
the different detectors would improve the localization results.This work was partially supported by USC Women in Science and Engineering (WiSE), the FI grant from the Generalitat de Catalunya, the European Social Fund, and the MID-CBR project grant TIN2006-15140-C03-01 and FEDER funds and the grant 2005-SGR-00093
