    Radiation Transport Modelling in a Tokomak Plasma: Application to Performance Prediciton and Design of Future Machines 

    Albajar Viñas, Ferran (Date of defense: 2001-06-14)

    The understanding and modelling of heat and radiation transport in tokamak plasmas is essential in order to progress in the development of thermonuclear fusion towards a practical energy source which meets all the future ...

    Scaling-up methodology : a systematical procedure for qualifying NPP nodalizations. Application to the OECD/NEA ROSA-2 and PKL-2 Counterpart test 

    Martínez Quiroga, Victor (Date of defense: 2014-11-17)

    System codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. Qualifying both codes and nodalizations is an essential step prior to their use in any significant study involving ...

    Second Harmonic Generation in Photonic Crystals 

    Trull Silvestre, José Francisco (Date of defense: 1999-12-21)

    Photonic crystals emerged at the end of the last decade as a new frame to control the interaction between radiation and matter. The potential advances that such structures could report in photonics technology has lead to ...
