Unary Pattern Avoidance in Partial Words Dense with Holes [chapter]

Francine Blanchet-Sadri, Kevin Black, Andrew Zemke
2011 Lecture Notes in Computer Science  
In this paper, we pose the problem of avoiding patterns in partial words very dense with holes.  ...  Previous work completed the classification of all unary patterns with respect to partial word avoidability, as well as the classification of all binary patterns with respect to non-trivial partial word  ...  Following all this, the next problem is how "dense" in holes can a partial word defined over a fixed alphabet be, while still avoiding a given pattern.  ...

Stereo vision for view synthesis

D. Scharstein
1996 Proceedings CVPR IEEE Computer Society Conference on Computer Vision and Pattern Recognition  
We also reevaluate the requirements on stereo algorithms for the application of view synthesis and discuss ways of dealing with partially occluded r egions of unknown depth and with completely occluded  ...  In other words, if an error in the computed disparities could be detected with an additional camera, then the view from this point can reveal the error.  ...  We can not exclude this case in natural environments, and thus holes can never be avoided completely. Dealing with this situation involves synthesizing texture for the newly visible areas.  ...

Fabrication of asymmetric tubular mixed-conducting dense membranes by a combined spin-spraying and co-sintering process

Zhengkun Liu, Guangru Zhang, Xueliang Dong, Wei Jiang, Wanqin Jin, Nanping Xu
2012 Journal of Membrane Science  
Mixed-conducting dense ceramic membranes have attracted considerable attention because of their potential application in oxygen separation, oxyfuel combustion and catalytic membrane reaction processes.  ...  However, the development of robust mixed-conducting membranes with both high permeability and stability is still a major challenge.  ...  From the outside surface of the membrane (Fig. 6a) , the ceramic gains with clear grain boundaries are visible, and the membrane surface is dense and free from cracks and holes.  ...

Influence of Oxygen Partial Pressure during Processing on the Thermoelectric Properties of Aerosol-Deposited CuFeO2

Thomas Stöcker, Jörg Exner, Michael Schubert, Maximilian Streibl, Ralf Moos
2016 Materials  
On these dense CuFeO 2 films deposited on alumina substrates with electrode structures, the Seebeck coefficient and the electrical conductivity were measured as a function of temperature and oxygen partial  ...  Hence, the influence of oxygen partial pressure during synthesis on the thermoelectric properties of Cu-Delafossites at high temperatures was investigated in this study.  ...  With increasing pO 2 , more oxygen is incorporated into the material, resulting in an increased hole concentration, resulting in an increasing electrical conductivity.  ...
