Exponential Runge-Kutta methods for stiff kinetic equations [PDF]

, 2010
We introduce a class of exponential Runge-Kutta integration methods for kinetic equations. The methods are based on a decomposition of the collision operator into an equilibrium and a non equilibrium part and are exact for relaxation operators of BGK ...

Shape Sensing of a Complex Aeronautical Structure with Inverse Finite Element Method

Sensors, 2021
The inverse Finite Element Method (iFEM) is receiving more attention for shape sensing due to its independence from the material properties and the external load. However, a proper definition of the model geometry with its boundary conditions is required,

Displacement and stress monitoring of a chemical tanker based on inverse finite element method [PDF]

, 2016
Real-time reconstruction of full field structural displacements, strains, and stresses by using surface strain measurements obtained from on-board strain sensors is commonly referred to as shape- and stress-sensing.

A quadrilateral inverse-shell element with drilling degrees of freedom for shape sensing and structural health monitoring

Engineering Science and Technology, an International Journal, 2016
The inverse Finite Element Method (iFEM) is a state-of-the-art methodology originally introduced by Tessler and Spangler for real-time reconstruction of full-field structural displacements in plate and shell structures that are instrumented by strain ...

Power spectrum optimization for interference mitigation via iterative function evaluation [PDF]

, 2012
Power spectrum optimization is a well-known difficult nonconvex optimization problem for which only local optimality can typically be assured. This paper unifies several classes of local optimization methods and proposes efficient and new methods for ...
