A Study of Nine Extremely Low Mass Ratio-contact Binary Systems
The Astronomical JournalLow-mass ratio systems (LMR) are a very interesting class of contact eclipsing binaries challenging the theoretical models of stability. These systems are also considered possible progenitors of the rare low-mass optical transients called red novae.

Homogenization of heterogeneous, fibre structured materials [PDF]
, 2013 This contribution presents a multi-scale homogenization method to model fibre structured materials. On the macroscopic level textiles are characterized by a large area-to-thickness ratio, such that a discretization with shell elements is numerically ...

Analysis of unsteady wave processes in a rotating channel [PDF]
The impact of passage rotation on the gas dynamic wave processes is analyzed through a numerical simulation of ideal shock-tube flow in a closed rotating-channel. Initial conditions are prescribed by assuming homentropic solid-body rotation.
