Monitorização remota e detecção de falhas em rede de Média Tensão
  João Gomes Mota, João Gonçalo Maciel
  LABELEC, S.A., Grupo EDP
  Actas do Forum Energia IST, volume 1, pp. 45 a 48, Maio 2004.

  in Portuguese

Abstract: EDP Distribution and LABELEC began a joint study to optimise the quality of service (QoS) of the Medium Voltage network. Acknowledging the various devices capable of QoS measurements and telecommunications spread across the network, we propose the use of these features to perform real-time, continuous, diagnosis of the network. The work plan is presented in the paper, highlighting the different features of each equipment, the communications scheme and the information architecture. Since most of the equipment is already installed on the network, there is room for significant improvements at a low cost, enhancing the QoS and the tools available for distribution management and network exploitation.

Keywords: Quality of Energy/Service, medium voltage network, telecommunications

Mobile Robot Localisation on Reconstructed 3D Models
  João Gomes-Mota, Maria Isabel Ribeiro
  Journal of Robotics and Autonomous Systems 31 (1-2) pp. 17-30, Elsevier Science, April 2000.

Abstract: This paper presents a two-layer mobile robot localisation solution based on a Laser Range Scanner applied on reconstructed 3D models. This solution encompasses a feature matching layer performing without an initial posture estimate; a second layer based on coordinate transforms to refine an initial posture estimate, and a third module to assess the likelihood of the results computed by the two layers.

Keywords: mobile robot localisation, laser scanner, 3D scene reconstruction, frame localisation.

Nota: This is a reviewed and extended version of the SIRS'98 paper.

The interactive presentations were prepared to the audiences were I presented the papers. I believe they are a good introduction to the papers. Moreover, they allow me to go beyond the constraints of the paper pages.

The presentations open a new browser window fit to the presentation size. I recommend the versions 4.0 of Netscape Navigator and Internet Explorer browsers for a better viewing.

Unfortunately, a new Document Object Model implemented in the 6.0 release of the Netscape and Microsoft browsers and some of the DynamicHTML pages are no longer acessible with these browsers (see the Notes, below).

  1. If you have any difficulty finding one of these papers, please contact me.
  2. The interactive presentations use extensively DynamicHTML (JavaScript + Cascading Style Sheets). Make sure you have these options enabled in your browser.
  3. You should be capable to see most of the presentations with version 3.0 browsers, although some layout errors may occur. Should this occur, please try to resize the window.
  4. If you can't see a page in a presentation to the bottom - probably due to the font variation, go back and open the page in a new, maximized, window.
  5. If you can't put to work the interactive effects on a page, please proceed to the next one. You may also contact me for assistance.
  6. For a complete listing of the publicatios of our group, please refer to the Publications page on the site of the Mobile Robotics Lab (LRM).
