Selective image segmentation is an important topic in medical imaging and real
applications. In this paper, we propose a weighted variational selective image segmentation …

A novel subdomain structural topology optimization method is proposed for the minimum
compliance problem based on the level sets with the parameterization of radial basis …

Over the years, several optimization techniques were widely used to find the optimum shape
and size of engineering structures (trusses, frames, etc.) under different constraints (stress …

Based on isogeometric boundary element method (IGA BEM) and piecewise constant level
set (PCLS) method, a new topology optimization approach is proposed to design the …

The paper deals with the structural optimization of the elastic body in unilateral contact with
a rigid foundation using the level set approach. A piecewise constant level set method is …

SUMMARY A new level set method for topology optimization of distributed compliant
mechanism is presented in this study. By taking two types of mean compliance into …

Eulerian derivatives of shape functionals in shape optimization can be written in two
formulations of boundary and volume integrals. The former is widely used in shape gradient …

We consider to solve numerically the shape optimization models with Dirichlet Laplace
eigenvalues. Both volume-constrained and volume unconstrained formulations of the model …

In this paper, we deal with some shape optimization geometrical inverse spectral problems
involving the first eigenvalue and eigenfunction of ap-Laplace operator, over a class of open …
