A varhatoan nagy erdeklodesre valo tekintettel a penteki szeminariumot 
egy nagyobb befogadokepessegu teremben, a szomszedos F29-es 
eloadoteremben fogjuk megtartani. Azok szamara, akik nem tudnak 
eljonni, a http://www.galileowebcast.hu oldalon az interneten kozvetitjuk.

                       "Statistical Physics of Human Mobility"

        Abstract: A range of applications, from predicting the spread of human
        and electronic viruses to city planning and resource management in
        mobile communications, depend on our ability to understand the 
mobility
        of individuals. Here I will study the mobility pattern of millions of
        anonymized mobile phone users  to understand the statistical
        characteristics of human trajectories.  I will show that human
        mobility follows reproducible scaling laws, which, however, deviate
        from the standard Levy flight or random walk based predictions. I will
        discuss  a simple model that can account for the observed anomalies in
        the scaling behavior. Finally, as an application, I will show that  by
        measuring the entropy of each individual's trajectory, we find can
        explore the underlying predictability of human mobility.
