Nonlinear evolution wave equation for an artery with an aneurysm: an exact solution obtained by the modified method of simplest equation

Autor: Nikolova, E. V., Jordanov, I. P., Dimitrova, Z. I., Vitanov, N. K.

We study propagation of traveling waves in a blood filled elastic artery with an axially symmetric dilatation (an idealized aneurysm) in long-wave approximation.The processes in the injured artery are modelled by equations for the motion of the wall

Primacy analysis of the system of Bulgarian cities

Autor: Dimitrova, Z. I., Ausloos, M.

We study the primacy in the Bulgarian urban system. Two groups of cities are studied: (i) the whole Bulgaria city system that contains about 250 cities and is studied in the time interval between 2004 and 2011; and (ii) A system of 33 cities, studied
