On ice-induced instability in free-surface flows. [PDF]
, 2007 The problem of stability of a water-coated ice layer is investigated for a free-surface flow of a thin water film down an inclined plane. An asymptotic (double-deck) theory is developed for a flow with large Reynolds and Froude numbers which is then used

Mechanical Instabilities of Biological Tubes [PDF]
Physical Review Letters, 2012 We study theoretically the shapes of biological tubes affected by various pathologies. When epithelial cells grow at an uncontrolled rate, the negative tension produced by their division provokes a buckling instability. Several shapes are investigated : varicose, enlarged, sinusoidal or sausage-like, all of which are found in pathologies of tracheal ...

Analysis of DC voltage oscillation mechanism in AC/DC hybrid distribution system
The Journal of Engineering, 2019 DC voltage oscillation occurs more and more frequently in voltage source converter (VSC)-based AC/DC hybrid distribution system (AC/DC HDS). However, currently, the explanation of the oscillation mechanism is not clear enough.
