Watermarking Algorithms for 3D NURBS Graphic Data
EURASIP Journal on Advances in Signal Processing, 2004 Two watermarking algorithms for 3D nonuniform rational B-spline (NURBS) graphic data are proposed: one is appropriate for the steganography, and the other for watermarking.

Generating NURBS cladding and structures with parametric programming and BIM
PARC: Pesquisa em Arquitetura e Construção, 2020 The process of designing and building curvilinear architectures is still challenging. The use of multiple applications with distinctive design paradigms are unlikely to disappear. The interoperability used here was not only the conventional one.

Attractive planar panelization using dynamic relaxation principles [PDF]
, 2015 In the presented paper a new method is proposed to approximate a given NURBS surface with a PQ (Planar Quad) mesh. The desired mesh layout will be generated in plan and then attracted to the target surface. The process iteratively pulls the mesh vertices

Robot‐Assisted Measurement of the Critical Micelle Concentration
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Computational Visual Media, 2017 Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as subdivision or NURBS. Both polygon models

The Anatomical Record, EarlyView.Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Dianzi Jishu Yingyong, 2018 Although the uniform theory of diffraction(UTD) could be theoretically applied to arbitrarily-shaped convex objects modeled by non-uniform rational b-splines(NURBS), one of the great challenges in calculation of the UTD surface diffracted fields is the ...

An isogeometric analysis for elliptic homogenization problems
, 2013 A novel and efficient approach which is based on the framework of isogeometric analysis for elliptic homogenization problems is proposed. These problems possess highly oscillating coefficients leading to extremely high computational expenses while using ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds
Computer Graphics Forum, EarlyView.The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.
