This paper introduces the notion of Lipschitz stability for nonlinear th order 8 matrix Lyapunov differential systems and gives sufficient conditions for Lipschitz stability. We develop variation of parameters formula for the solution of the nonhomogeneous nonlinear th order matrix Lyapunov differential system. We 8 study observability and controllability of a special system of th order nonline...

Grain-size distributions and thicknesses of tephra layers are used to reconstruct characteristics, dynamics, hazards explosive volcanic eruptions, but the extent which preservation is influenced by depositional environments unclear. This paper analyses grain-size produced Eyjafjallajökull (2010) Grímsvötn (2011) eruptions. We collected 110 samples layer thickness measurements from 86 sites at t...
