Shape optimization vs topology optimization
WebbIn this thesis, we will propose mathematical models and methods based on partial differential equations to compress images and videos. In the first part, we will propose a mathematical criterion allowing us to locate the best pixels to keep within an image in the case where the inpainting method is the heat equation. To do so, we will write the … WebbThis formulation involves a variable ground structure for topology optimization, since the shape of the shell mid-plane is modified in the course of the process. It was considered a simple type of design problem, where the optimization goal is to minimize the compliance with respect to the variables that control the shape, material fraction and orientation, …

WebbTopology optimization has been available since 1900 [1]. There are several survey papers dealing with this in the litera-ture [2,3]. Topology optimization is used for two major pur-poses: shape optimization and layout optimization. In the present study emphasis is on the use of topology optimization for determining the best structural layout. WebbTopology optimization has evolved rapidly since the late 1980s. The optimization of the geometry and topology of structures has a great impact on its performance, and the last …
