Uncertainty quantification for linear elastic bodies with two fluctuating input parameters

Topology Optimization of Two Linear Elastic Bodies in Unilateral Contact

Abstract The optimal solutions are most sensitive to the boundary conditions when performing topology optimization of components. In many applications the design domain of the components are subjected to unilateral contact conditions. In order to obtain relevant conceptual designs by topology optimization of such systems, the contact conditions should be included explicitly in the optimization....

New family of Two-Parameters Iterative Methods for Non-Linear Equations with Fourth-Order Convergence

Error Estimation and Uncertainty Quantification for non-linear CFD problems

Modern research and engineering rely on numerical simulations to predict the behaviour of fluids and some derived physical quantities of interest. These predictions are often strewn with errors and uncertainties. Numerical errors come from replacing the real physics with approximate models solved by numerical approximations, while uncertainties are due to insufficient knowledge of some input va...

Recognition criteria vary with fluctuating uncertainty.

In distinct experiments we examined memories for orientation and size. After viewing a randomly oriented Gabor patch (or a plain white disk of random size), observers were given unlimited time to reproduce as faithfully as possible the orientation (or size) of that standard stimulus with an adjustable Gabor patch (or disk). Then, with this match stimulus still in view, a recognition probe was p...

PD Controller Design with H¥ Performance for Linear Systems with Input Delay

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
