INDIVIDUAL MOBILITY GRANT No. IMG-96-BG-2061
Awarded to Dr. Ana Proykova by The European
to prepare case studies for the specializing
course Statistical Methods in Nuclear Physics
Host Institution: The Catholic University
B-1348, Lovain-la-Neuve, Belgium
Title of the course: Statistical Methods in
Nuclear Physics: I, II
Part One: A specializing course for the Master
Program in Physics (Data analysis in Nuclear and High Energy
Part two: A specializing course for the Master
and Ph.D. Program in Physics (Computer Simulations in Statistical
Home institution: The St. Kliment Ohridski University
This course has been existing and new cases has been
adding to it. Its original structure was based on two parts. The
first part covers selected topics from the statistics and data
analysis necessary to handle experimental data taken by the modern
set-up. It is included in the Master Program at the Faculty of
Physics, the University of Sofia).
The second part gives the students ideas of how natural
processes can be simulated by using computers. It provides a specializing
education for students enrolled in both the Master and the Ph.D.
programs in Theoretical Physics.
As a result of the project, the specializing course
Statistical Methods in Nuclear Physics included in the M.
Program at the Faculty of Physics, University of Sofia covers
the same topics as such a course available at the Institute of
Physics, the Catholic University of Louvain.
Objectives: The course
on Data analysis in Nuclear and High Energy Physics is
intended to cover selected topics from the probabilistic theory
and statistics applied in the specified fields of physics and
thus providing a specializing education for students enrolled
in the Master Program.
