Web1 de dez. de 2012 · Highlights Hierarchical refinement of NURBS offers full analysis suitability, straightforward implementation and simple generalization to 3D. We first explore local hierarchical refinement for adaptive NURBS-based IGA. We then combine the B-spline version of the FCM and hierarchical refinement for a seamless design-through … Webmotor and a transformer (Scheu et al., 2024) in a hierarchical structure. Using the HS model, it is also possible to predict the failure of equipment components in a hierarchical structure. The remainder of this paper consists of five sections. Section 2 introduces the background for failure forecasting and HS model.

As illustrated in Fig. 1 , cells with a higher refinement level can be created by … WebWe present an adaptive B‐spline FEM that employs hierarchical refinement and coarsening techniques. Hierarchical B‐spline refinement augments the approximation space through the use of finer, more compactly supported B‐splines. With this approach compatibility is automatic because problematic T‐vertices do not arise.
Web14 de out. de 2024 · In this paper, we propose a simple yet effective approach, i.e., Hierarchical and Interactive Refinement Network (HIRN), to preserve the edge structures in detecting salient objects. In particular, a novel multi-stage and dual-path network structure is designed to estimate the salient edges and regions from the low-level and high-level …
Web1 de set. de 2024 · The hierarchical approach to adaptive spline refinement has lately been revisited, resulting in the introduction of truncated hierarchical B-splines [10].
