Ruin probability in finite time [PDF]
, 2011 In examining the nature of the risk associated with a portfolio of business, it is often of interest to assess how the portfolio may be expected to perform over an extended period of time. One approach involves the use of ruin theory (Panjer and Willmot, 1992).

Universality of finite-time disentanglement [PDF]
Physical Review A, 2016 In this paper we investigate how common is the phenomenon of Finite Time Disentanglement (FTD) with respect to the set of quantum dynamics of bipartite quantum states with finite dimensional Hilbert spaces. Considering a quantum dynamics from a general sense, as just a continuous family of Completely Positive Trace Preserving maps (parametrized by the ...

Passivity-Based Twisting Sliding Mode Control for Series Elastic Actuators
ActuatorsThis paper presents a passivity-based twisting sliding mode control (PBSMC) approach for series elastic actuators (SEAs). To address the time-varying position trajectory tracking control problem in SEAs, a fourth-order dynamic model is developed to ...

Faster 3D finite element time domain : Floquet absorbing boundary condition modelling using recursive convolution and vector fitting [PDF]
, 2009 A recursive convolution (RC) based on the vector fitting (VF) method and triangular temporal basis functions is employed to compute the Floquet absorbing boundary condition (FABC) formulation in the vector 3D finite element time-domain (FETD) modelling ...

Vehicle-bridge dynamic interaction using finite element modelling [PDF]
, 2010 First investigations on the dynamic response of bridges due to moving loads were motivated by the collapse of the Chester railway bridge in the UK in the middle of the 19th century.
