Refinable spaces and local approximation estimates for hierarchical splines
(Oxford University Press, 2017-07)
We study the local approximation properties in hierarchical spline spaces through multiscale quasi-interpolation operators. This construction suggests the analysis of a subspace of the classical hierarchical spline space ...
Gradual Refinement Types
(2017)
Refinement types are an effective language-based verification technique. However, as any expressive typing discipline, its strength is its weakness, imposing sometimes undesired rigidity. Guided by abstract interpretation, ...
Comparison Of Adaptive Multiresolution And Adaptive Mesh Refinement Applied To Simulations Of The Compressible Euler Equations
(SIAM PublicationsPhiladelphia, 2016)
Algorithms for the implementation of adaptive isogeometric methods using hierarchical B-splines
(Elsevier Science, 2018-01)
In this article we introduce all the ingredients to develop adaptive isogeometric methods based on hierarchical B-splines. In particular, we give precise definitions of local refinement and coarsening that, unlike previously ...
Refinería Cartagena Oil Refining Company
(1915)
Vista del local en donde operaba la Cartagena Oil Refining Company, (1908-1923), a la entrada de Bocagrande. Propiedad de Diego Martínez Camargo, esta refinería funcionó entre 1909 y 1923. Producía principalmente querosene ...
Spline-based methods with adaptive refinement for problems of acoustics and fracture mechanics of thin plates
(Universidad de Chile, 2018)
Both the CAD software and FEM software have a significant impact on engineering nowadays. Even though both are powerful tools for design and analysis, the main drawback is that CAD geometries and Finite Element models do ...
Average adjacencies for tetrahedral skeleton-regular partitions
(ELSEVIER SCIENCE BV, 2005-05-01)
For any conforming mesh, the application of a skeleton-regular partition over each element in the mesh, produces a conforming mesh such that all the topological elements of the same dimension are subdivided into the same ...
