... is capable of modeling tubular vessel segments as well as bifurcations. The editing capability can be used for completing partially segmented vascular information such as the topology and radius, as well as designing normal vascular structure or pathological vascular structure such as the aneurysm...

... on the level set method and the finite element method (FEM). First, an optimization problem is formulated that addresses the design of compliant thermal actuators considering the magnitude of the displacement at the output location. Next, the topological derivatives that are used when introducing holes during...

...Charlie C. L. Wang This paper presents an approach to automatically recover mesh surfaces with sharp edges for solids from their binary volumetric discretizations (i.e., voxel models). Our method consists of three steps. The topology singularity is first eliminated on the binary grids so...

...Waldemar Celes; Glaucio H. Paulino; Rodrigo Espinha State-of-the-art numerical analyses require mesh representation with a data structure that provides topological information. Due to the increasing size of the meshes currently used for simulating complex behaviors with finite elements or boundary...

..., etc) on large databases of solid models. We introduce an approach to compare models based on shape using information extracted from the model boundary representation into Model Signature Graphs . We show how the Model Signature Graphs can be used to compute topological distances among models and how...

... and are arranged according to an arbitrary irregular curve mesh topology (Fig. 1). The surface constructed from these data will minimize flexibly chosen fairness criteria. The set of available fairness criteria is able to measure surface characteristics related to curvature, variation of curvature, and higher...

...Masatake Higashi; Hisashi Nakano; Atsuhide Nakamura; Mamoru Hosaka This paper introduces topological constraints to robustly and comprehensively process interference calculation in solid modeling and feature modeling, and describes a method of symbolic notation of their expressions and algorithms...
