A Novel Vision-Based Outline Extraction Method for Hull Components in Shipbuilding

Journal of Marine Science and Engineering
The diverse nature of hull components in shipbuilding has created a demand for intelligent robots capable of performing various tasks without pre-teaching or template-based programming. Visual perception of a target’s outline is crucial for path planning

Three-dimensional random Voronoi tessellations: From cubic crystal lattices to Poisson point processes [PDF]

, 2008
We perturb the SC, BCC, and FCC crystal structures with a spatial Gaussian noise whose adimensional strength is controlled by the parameter a, and analyze the topological and metrical properties of the resulting Voronoi Tessellations (VT).

Construction of Pattern Optimization Model Driven by Fabric Parameters in 3D Garment Development Using Artificial Neural Networks

Technologies
Fabric properties significantly influence the accuracy of pattern dimensions derived from 3D scanned garment samples. To enhance the generated pattern accuracy, a novel predictive model was proposed to estimate the pattern dimension change ratio by ...

One machine, one minute, three billion tetrahedra

, 2018
This paper presents a new scalable parallelization scheme to generate the 3D Delaunay triangulation of a given set of points. Our first contribution is an efficient serial implementation of the incremental Delaunay insertion algorithm. A simple dedicated

An Efficient Mesh Generation Method for Fractured Network System Based on Dynamic Grid Deformation

Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
Meshing quality of the discrete model influences the accuracy, convergence, and efficiency of the solution for fractured network system in geological problem. However, modeling and meshing of such a fractured network system are usually tedious and difficult due to geometric complexity of the computational domain induced by existence and extension of ...

Load-Balancing for Parallel Delaunay Triangulations [PDF]

, 2019
Computing the Delaunay triangulation (DT) of a given point set in $\mathbb{R}^D$ is one of the fundamental operations in computational geometry. Recently, Funke and Sanders (2017) presented a divide-and-conquer DT algorithm that merges two partial ...

Reconstructing Curves from Sparse Samples on Riemannian Manifolds

Computer Graphics Forum, Volume 43, Issue 5, August 2024.
Abstract Reconstructing 2D curves from sample points has long been a critical challenge in computer graphics, finding essential applications in vector graphics. The design and editing of curves on surfaces has only recently begun to receive attention, primarily relying on human assistance, and where not, limited by very strict sampling conditions.

FAUST Observations in the Fourth Galactic Quadrant

, 1999
We analyze UV observations with FAUST of four sky fields in the general direction of the fourth Galactic quadrant, in which we detect 777 UV sources. This is ~50% more than detected originally by Bowyer et al (1995).

A system dynamics approach to modelling eco‐innovation drivers in companies: Understanding complex interactions using machine learning

Business Strategy and the Environment, Volume 33, Issue 5, Page 4456-4479, July 2024.
Abstract This paper examines the effect of drivers in the development of eco‐innovation from a system dynamics perspective. While previous literature has made important contributions in identifying factors that influence the development of eco‐innovations, there remains limited understanding of how these drivers act and interact in promoting its ...
