Quasi-conformal Flat Representation of Triangulated Surfaces for Computerized Tomography [chapter]

Eli Appleboim, Emil Saucan, Yehoshua Y. Zeevi
2006 Lecture Notes in Computer Science  
In this paper we present a simple method for flattening of triangulated surfaces for mapping and imaging. The method is based on classical results of F. Gehring and Y.  ...  Väisälä regarding the existence of quasi-conformal and quasi-isometric mappings between Riemannian manifolds. A random starting triangle version of the algorithm is presented.  ...  The authors would like to thank Ofir Zeitoun and Efrat Barak and Amiad Segal and Ronen Lev for their dedicated and skillful programming of the algorithms.  ...

Method Both steps require multi-scale transformation of the (four-dimensional) data into the wavelet domain. For the first step a 'coarse-grained representation' [4] of the data is obtained.  ...  (in the case of positron emission tomography data) or an average over a run (as can be the case with functional MRI data sets).  ...  Previous hippocampal shape studies often use volumetric representations [2,3]. We feel that surface-based techniques are more appropriate, since the surface of an object actually defines its shape.  ...

Performance of optimized sound field control techniques in simulated and real acoustic environments

Philip Coleman, Martin Møller, Martin Olsen, Marek Olik, Philip Jackson, Jan Abildgaard Pedersen
2012 Journal of the Acoustical Society of America  
Test results showed that substitution of a hard surface flooring material for carpeting resulted in a net increase in corridor noise levels with the expected patient and medical professional perceptions  ...  However, if the hard surface flooring is combined with a high performance acoustical ceiling, then the rise in noise due to the floor surface is negated with the added absorption of the improved ceiling  ...  A non-destructive method of steel billet, which uses time-of-flight of ultrasonic longitudinal wave and detects defects as decrement of pseudo sound velocity reconstructed by computerized tomography, has  ...
