      Effect of Bi-doping and Mg-excess on the thermoelectric properties of Mg2Si materials 

      Ioannou, M.; Polymeris, G. S.; Hatzikraniotis, E.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2014)
      In this work, Bi-doped magnesium silicide compounds were prepared by applying a combination of both, short-time ball milling and heating treatment. The effect of Mg excess was also studied, aiming towards further improvement ...

      An inverse method to assign receptances by using classical vibration absorbers 

      Zhu, J.; Mottershead, J. E.; Kyprianou, Andreas (2009)
      The classical mass-spring absorber can be thought of as a very simple structural modification. In this paper the inverse problem of assigning receptances to a dynamic system by using one or more simple mass-spring absorbers ...

      Minimum relative entropy criterion for damage detection and location 

      Mares, C.; Kyprianou, Andreas (Affiliation: Brunel University, School of Engineering and Design, United KingdomAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, CyprusCorrespondence Address: Mares, C.Brunel University, School of Engineering and DesignUnited Kingdomemail: Cristinel.Mares@brunel.ac.uk, 2009)
      Relative entropy has been employed, as an alternative to other regularization methods, in solving ill-conditioned linear inverse problems. Damage detection when treated as structural modification imparted by the damage ...

      Solid-state synthesis and thermoelectric properties of Sb-doped Mg 2Si materials 

      Ioannou, M.; Polymeris, G.; Hatzikraniotis, E.; Khan, A. U.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2013)
      Sb-doped magnesium silicide compounds have been prepared through ball milling and solid-state reaction. Materials produced were near-stoichiometric. The structural modifications have been studied with powder x-ray diffraction. ...
