    • A hFSM based cognitive control architecture for assistive task in R-MIS 

      Casals Gelpi, Alicia; Sayols Baixeras, Narcís; Hernansanz Prats, Alberto (2020)
      Conference report
      Open Access
      SARAS aims to develop assistive surgical robots for laparoscopic MIS, autonomously operating in the same workspace of either a teleoperated surgical robot or a manually driven surgical tool. The auxiliary robots autonomously ...
    • Assistance strategies for robotized laparoscopy 

      Casals Gelpi, Alicia; Hernansanz Prats, Alberto; Sayols Baixeras, Narcís; Amat Girbau, Josep (Springer, 2020)
      Part of book or chapter of book
      Open Access
      Robotizing laparoscopic surgery not only allows achieving better accuracy to operate when a scale factor is applied between master and slave or thanks to the use of tools with 3 DoF, which cannot be used in conventional ...
    • Computer algebra tales on Goppa codes and McEliece cryptography 

      Sayols Baixeras, Narcís; Xambó Descamps, Sebastián (2020-06)
      Article
      Open Access
      The 40-year old McEliece public-key crypto-system is revisited with the help of recently developed resources: an improved Peterson–Gorenstein–Zierler decoder for alternant error-correcting codes; PYECC, a purely Python ...
    • Mathematical methods of signal processing 

      Sayols Baixeras, Narcís (Universitat Politècnica de Catalunya, 2011-11)
      Master thesis
      Open Access
      The aim of this project is to present in a systematic way the more relevant mathematical methods of signal processing, and to explore how they are applied to speech and image precessing. After explaining the more common ...
    • Multi-task control strategy exploiting redundancy in RMIS 

      Casals Gelpi, Alicia; Hernansanz Prats, Alberto; Sayols Baixeras, Narcís; Pieras Morell, Tomas (2020)
      Conference report
      Open Access
      A single master single slave teleoperation platform was developed to assist the surgeon during Fetoscopic laser Photocoagulation. The master is composed of a 6DoF haptic device and an interactive user interface containing ...
    • New technologies in surgery 

      Casals Gelpi, Alicia; Sayols Baixeras, Narcís; Amat Girbau, Josep (Springer, 2017)
      Conference report
      Restricted access - publisher's policy
      The progress of technology and robotics in industry has not yield to an equivalent development in the medical field. This paper analyses surgical proce-dures from the point of view of industrial processes looking for ...
    • Pattern modelling and pattern processing in image and speech signals 

      Sayols Baixeras, Narcís (Universitat Politècnica de Catalunya, 2012-07-24)
      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] In the context of signal processing, the aim of this memoir is to explore the pattern theory (PT) of Grenander and Mumford by focussing on two proof-of-concept applications, one dealing with images and the other ...
    • Technical and functional validation of a teleoperated multirobots platform for minimally invasive surgery 

      Leporini, Alice; Oleari, Elettra; Landolfo, Carmela; Sanna, Alberto; Larcher, Alessandro; Gandaglia, Giorgio; Fossati, Nicola; Muttin, Fabio; Capitanio, Umberto; Montorsi, Francesco; Sayols Baixeras, Narcís; Hernansanz Prats, Alberto; Casals Gelpi, Alicia (2020-05)
      Article
      Open Access
      Nowadays Robotic assisted Minimally Invasive Surgeries (R-MIS) are the elective procedures for treating highly accurate and scarcely invasive pathologies, thanks to their ability to empower surgeons’ dexterity and skills. ...
    • Vision based robot assistance in TTTS fetal surgery 

      Sayols Baixeras, Narcís; Hernansanz Prats, Alberto; Parra Hernández, Johanna; Eixarch Roca, Elisenda; Gratacós Solsona, Eduard; Amat Girbau, Josep; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      This paper presents an accurate and robust tracking vision algorithm for Fetoscopic Laser Photo-coagulation (FLP) surgery for Twin-Twin Transfusion Syndrome (TTTS). The aim of the proposed method is to assist surgeons ...
