On the electrochemical properties of platinum stepped surfaces vicinal to the (100) pole. A computational study

Ferre Vilaplana, Adolfo; Gisbert, Ruben; Herrero, Enrique (Elsevier, 2014-04-10)

DFT studies on platinum stepped surfaces have been carried out in order to understand the differences in the electrochemical behavior between the surfaces with (111) and (100) terraces. Thus, adsorption energies of different ...
On the Results of the First Mobile Biometry (MOBIO) Face and Speaker Verification Evaluation

Marcel, Sebastien; McCool, Chris; Matejka, Pavel; Ahonen, Timo; Cernocky, Jan; Chakraborty, Shayok; Balasubramanian, Vineeth; Panchanathan, Sethuraman; Chan, Chi Ho; Kittler, Josef; Poh, Norman; Fauve, Benoit; Glembek, Ondrej; Plchot, Oldrich; Jancik, Zdenek; Larcher, Anthony; Albiol Colomer, Antonio José; Monzó Cuenca, José David (Springer Verlag (Germany), 2010)

This paper evaluates the performance of face and speaker verification techniques in the context of a mobile environment. The mobile environment was chosen as it provides a realistic and challenging test-bed for biometric ...
On the use of diagonal and class-dependent weighted distances for the Probabilistic k-nearest neighbor

Paredes Palacios, Roberto; Girolami, Mark (Springer Verlag (Germany), 2011)

A probabilistic k-nn (PKnn) method was introduced in [13] under the Bayesian point of view. This work showed that posterior inference over the parameter k can be performed in a relatively straightforward manner using Markov ...
