Ruin probability in finite time [PDF]

open access: yes, 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).

Faster 3D finite element time domain : Floquet absorbing boundary condition modelling using recursive convolution and vector fitting [PDF]

open access: yes, 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 ...

Research Of Finite-time Event-triggered Control For High-speed Train Under Switching Topology

open access: yesJournal of Applied Science and Engineering, 2022
A finite-time event-triggered model control strategy is proposed for multi-train high-speed train systems (MHSTs) with switching topologies. Due to the complexity of the high-speed railway operation environment, the communication topology of MHSTs is ...

New Results on Finite-Time Stability: Geometric Conditions and Finite-Time Controllers [PDF]

open access: yes2018 Annual American Control Conference (ACC), 2018
This paper presents novel controllers that yield finite-time stability for linear systems. We first present a sufficient condition for the origin of a scalar system to be finite-time stable. Then we present novel finite-time controllers based on vector fields and barrier functions to demonstrate the utility of this geometric condition. We also consider

The finite-volume method in computational rheology [PDF]

open access: yes, 2012
The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

Finite-Time Weighted Average Consensus and Generalized Consensus Over a Subset

open access: yesIEEE Access, 2016
In this paper, the finite-time consensus for arbitrary undirected graphs is discussed. We develop a parametric distributed algorithm as a function of a linear operator defined on the underlying graph and provide a necessary and sufficient condition ...

Prescribed Performance Control of Marine Surface Vessel Trajectory Tracking in Finite-Time with Full-State Constraints and Input Saturation

open access: yesJournal of Marine Science and Engineering, 2021
This manuscript mainly solves a fully actuated marine surface vessel prescribed performance trajectory tracking control problem with full-state constraints and input saturation. The entire control design process is based on a backstepping technique.

Finite-Time Projective Synchronization of Stochastic Complex-Valued Neural Networks With Probabilistic Time-Varying Delays

open access: yesIEEE Access, 2021
This paper addresses finite-time projective synchronization of stochastic complex-valued neural networks (SCVNNs) with probabilistic time-varying delays (PTVs). First, in the complex domain, PTVs are introduced into the studied model and a novel feedback
