We develop a new optimisation technique that combines multiresolution subdivision
surfaces for boundary description with immersed finite elements for the discretisation of the …

Local shape control methods, such as B-spline surfaces, are well-conditioned such that they
allow high-fidelity design optimization; however, this comes at the cost of degraded …

Engineers routinely perform parameter studies to investigate how system response changes
over a range of parameter values. This can provide engineering insight into the importance …

This article aims to contribute to numerical strategies for PDE-constrained multiobjective
optimization, with a particular emphasis on CPU-demanding computational applications in …

A new airfoil shape parameterization method is developed, which extended the Bezier curve
to the generalized form with adjustable shape parameters. The local control parameters at …

Reduced-order models based on Proper orthogonal decomposition are known to suffer from
a lack of accuracy due to the truncation effect introduced by kee** only the most energetic …

We present a method for constructing design-appropriate shape parameterizations of
discrete surfaces for optimization of flight vehicles. The method allows the designer to …

In this paper, we propose the use of Genetic Algorithms as a tool for improving a pacemaker
efficiency in a defective heart. Such device is generally used when the electrical activity of …

This paper presents and analyzes a new multigrid framework to solve shape optimization
problems governed by elliptic PDEs. The boundary of the domain, ie, the control variable, is …

Adjoint methods are the most e cient approach to compute the design sensitivities as the
entire gradient vector of a single objective function is obtained in a single adjoint system …
