### Excellent Master Theses

Three prizes have been awarded (in alphabetical order):

SMC's prize for excellent Master Thesis in Mathematics 2012/2013 is awarded to

- Shlok Datye, KTH

for *Money management principles for mechanical traders*, a thesis in Mathematical Finance, which shows a remarkable understanding of the subject. This innovative thesis provides sound mathematical justifications and extensions of a number of popular trading strategies, and gives unique insights into the field of mechanical trading, from mathematical rigour to practical implementation advice.

Thesis advisor: Filip Lindskog, KTH.

SMC's prize for excellent Master Thesis in Mathematics 2012/2013 is awarded to

- Mikael Hansson, SU

for *On generalized Ramsey numbers for two sets of cycles, *a thesis which establishes substantial new results within Ramsey Theory, a classical topic in combinatorics that dates back to the 1930's. The author displays mathematical prowess and maturity, as well as pedagogical skills in structuring very complicated arguments.

SMC's prize for excellent Master Thesis in Mathematics 2012/2013 is awarded to

- Erik Peldan, KTH

for *Computation of air-vortices based on GPU technology: optimizing and parallelizing a model for wake-vortex prediction using OpenCL,* a thesis in Scientific Computing. The work, which was carried out at the company AVTECH, was driven by important engineering applications. The author has made unique contributions to all aspects of this interdisciplinary subject: derivation of a mathematical model for the physical process, construction of numerical methods, sophisticated implementation as well as a critical evaluation of the model.
