    • Influence of Cu on the properties of gadolinium-doped barium cerate 

      Gorbova, E.; Maragou, V.; Medvedev, D.; Demin, A.; Tsiakaras, P. (2008)
      In the present work the effect of copper oxide addition on the densification behavior and electrical conductivity of BaCe1-xGdxO3-delta (BCG) type ceramics is investigated. Small addition (1 mol%) of this sintering additive ...

    • Investigation of the protonic conduction in Sm doped BaCeO3 

      Gorbova, E.; Maragou, V.; Medvedev, D.; Demin, A.; Tsiakaras, P. (2008)
      In the present work the structural and electrical properties of samarium-doped barium cerate perovskites of BaCe1-xSmxO3-delta formula (with x=0-0.2), prepared by following the solid state reaction method, are investigated. ...

    • Management zones delineation using fuzzy clustering techniques in grapevines 

      Tagarakis, A.; Liakos, V.; Fountas, S.; Koundouras, S.; Gemtos, T. A. (2013)
      Precision viticulture aims at managing vineyards at a sub-field scale according to the real needs of each part of the field. The current study focused on delineating management zones using fuzzy clustering techniques and ...
