Goal:

analyze geographic and transportation information taking into account
multimodal transportation network (i.e. transportation network composed
of, for example, bus, rail, bicycle and sidewalks layers).
Requirements:

Computation of critical currents in superconductors
Co-advisors:

Goal:
To calculate current circulation maps in ceramic superconductor materials of
the YBaCuO kind, taking into account magnetic field measurements made on the
outside.
Application:
Superconductor ceramics, discovered less than 15 year ago start to see light
as industrial applications (feed-bars,SQUIDS, current limiters, etc. ).
These apppliances need three-dimensional centimeter-size bits. But the
great sensitivity of superconductivity to cristalization defects in the
material cause circulation of current in samples of that size to be irregular.
Control of the quality of the material is critical. It is of uttermost importance to
compute the current through the sample non-destructively. This problem has
been the subject of our cooperation with the electromagnetism and
superconductivity group of the Institute of Materials Science
Institut de Ciència de Materials
de Barcelona,of the CSIC, the Research Council of Spain, led by
X. Oradors from 1996.
Implementation:
The goal of this project is the computation of the critical current
in samples of plane cristalization. The magnetization of the sample is
approximated by a discrete function and this allows for the linearization of
the problem and the resolution throgh a QR Householder decomposition. The
size of the resulting system calls for an "out of core" method , that is,
only a part of the system is resident in RAM memory at any one time.
But the
problem can be solved on a PC with Linux.
The error control on this critical current computation will be done by
comparison of the results of a computation of the results of measures of the
magnetic field on the sample at different heights with those of a program of
direct computation of numerical integrations of the Biot-Savart law, of the
magnetic field generated by the current yield.
Once this application is developed its use will be offered to the groups
that synthesize these superconducting samples through a UPC server.
For the visualization of data we will use Matlab and Octave, with GNUPlot.

Representation of 3D Digital Images under the EVM model. Conversion
algorithms.
Dolors Ayala Vallespí.
You can send an e-mail dolorsa@lsi.upc.es
This project consists of the implementation of an algorithm to obtain
the frontier of a 3D digital image usin the EVM model as an intermediate.
The initial datum is an image in the usual voxels model. An EVM-formatted
model will be obtained and, then, the frontier will be rebuilt.
NOTE: This project is suitable for one or two students.

This project will apply a decomposition system called Alternate Addition
of Volumes on the simplest cse of orhogonal polyhedra represented under
the EVM model.
This method supports the representation of an object as the alternate
addition of convex volumes (in this case, boxes) and also as a
sequence of volumes to be extracted from an initial box.
NOTE: This project is suitable for one or two students.
