Lots of activities during the summer of 2013

The summer of 2013 will be a very interesting one for us. In June we will participate in four conferences, in Lithuania and abroad, and present five reports (4 talks and 1 poster) on the most recent research done by us. During July and August we will have two students-trainees, who will participate in the project "Promotion of Student Scientific Activities" from the Research Council of Lithuania. The training will be held on the topics of "Economic convergence as thermodynamic appreciation of real currency exchange rate" (supervisor dr. (HP) Vygintas Gontis; student-trainee Kęstutis Acus) and "Controling complex stochastic systems" (supervisor Aleksejus Kononovicius; student-trainee Ignas Kazakevičius).

Belousov-Zhabotinsky reaction

Belousov-Zhabotinsky reaction [1] is a chemical reaction, or more precisely a reaction family, known for exhibiting temporal and spatial oscillations.

This reaction is one of the classical examples of the natural non-linear oscillations. Another prominent example is the previously analyzed prey-predator interactions in the ecosystem. Interestingly enough despite being of a very different nature both of these example can be modeled using Lotka-Volterra equations.

In this text we will also consider certai cellular automaton, which replicates the spatial oscillations seen in some of the Belousov-Zhabotinsky reactions.

Prisoner's dilemma

Previously we wrote about mathematical "puzzle" originating from a TV game (see the description of the Monty Hall problem). This time we shall consider the opposite case - the mathematical "game" used as a base for a TV game. Watch a fragment of the "Golden Balls" final stage called "Split or steal".

The game is very simple, yet about what constitutes an optimal play or correct solution we could argue a lot. It is even used to understand social behavior in humans [1].

RCL: Call for applications for Students' Research Practice in Lithuania in summer 2013

Research Council of Lithuania has announced a call for applications for students' research practice in Lithuania in summer of 2013. The contributors towards Physics of Risk website, dr. (HP) Vygintas Gontis and PhD student Aleksejus Kononovicius, offer two topics for the research practice. The offered topics are mainly based on the following topics, previously published on this website:

  • Economic convergence as thermodynamic appreciation of real currency exchange rate
  • Agents-leaders influence on the Kirman’s herding model dynamics
