Distributed shape derivative via averaged adjoint method and applications [PDF]
, 2015 The structure theorem of Hadamard-Zol\'esio states that the derivative of a shape functional is a distribution on the boundary of the domain depending only on the normal perturbations of a smooth enough boundary.

Designing an Optimal Shape Warehouse [PDF]
, 2013 The paper addresses the topic of designing the shape of a warehouse and shows a comparison between a standard storage-handling system, which is designed taking into account the minimization of the handling planar path, and the one which is designed trying to minimizing the overall handling energy consumption.

Reconstructing 3D Shapes From Multiple Sketches Using Direct Shape Optimization
IEEE Transactions on Image Processing, 2020 3D shape reconstruction from multiple hand-drawn sketches is an intriguing way to 3D shape modeling. Currently, state-of-the-art methods employ neural networks to learn a mapping from multiple sketches from arbitrary view angles to a 3D voxel grid ...
