    • Study and evaluation of the performance of a multistage solid-propellant rocket vehicle, including atmospheric ascent and orbital insertion 

      Vergés Eiras, Roger (Universitat Politècnica de Catalunya, 2021-06-21)
      Bachelor thesis
      Open Access
      En aquest projecte s'estudia i s'avalua el rendiment d'un coet de diverses etapes de propel·lent sòlid durant tot el seu ascens atmosfèric i fins a la seva inserció orbital. Per tant, en primer lloc s'analitza la composició ...
    • Study of feasibility of a mission to Mars using aerocapture technique 

      Belart Bayo, Oscar (Universitat Politècnica de Catalunya, 2012-07)
      Master thesis (pre-Bologna period)
      Open Access
      Aerocapture is a brand new technique of orbit insertion, which consists in the energy depletion of a spacecraft using atmospheric drag. This decelerates the space vehicle and changes its trajectory from hyperbolic orbit ...

      The ultimate accuracy and precision of conventional1 and interferometric2 Global Positioning Satellite System Rerflectometry (GNSS-R) techniques for mesoscale ocean altimetry are still a matter of debate in the scientific ...
    • Validating a timing simulator for the NGMP multicore processor 

      Jalle Ibarra, Javier; Abella Ferrer, Jaume; Fossati, Luca; Zulianello, Marco; Cazorla Almeida, Francisco Javier (European Space Agency (ESA), 2016)
      Conference report
      Open Access
      Timing simulation is a key element in multicore systems design. It enables a fast and cost effective design space exploration, allowing to simulate new architectural improvements without requiring RTL abstraction levels. ...
