Curves defined by a class of discrete operators: Approximation result and applications
Mathematical Methods in the Applied Sciences, Volume 48, Issue 2, Page 2388-2403, 30 January 2025.In approximation theory, classical discrete operators, like generalized sampling, Szász‐Mirak'jan, Baskakov, and Bernstein operators, have been extensively studied for scalar functions. In this paper, we look at the approximation of curves by a class of discrete operators, and we exhibit graphical examples concerning several cases. The topic has useful

Ruling Based Design Method of Curved Origami
JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.ABSTRACT Curved origami attracts the attention of designers in recent years for the potential in the field of building structures for free form curved design. For practical use, the design methods are required to link the mathematically obtained curved surface and the requirements of architectural functions.

A GEOMETRIC PROCESSING WORKFLOW FOR TRANSFORMING REALITY-BASED 3D MODELS IN VOLUMETRIC MESHES SUITABLE FOR FEA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Conservation of Cultural Heritage is a key issue and structural changes and damages can influence the mechanical behaviour of artefacts and buildings. The use of Finite Elements Methods (FEM) for mechanical analysis is largely used in modelling stress ...
