Reconstructing Geometrical Models of Indoor Environments Based on Point Clouds

open access: yesRemote Sensing, 2023
In this paper, we present a workflow that combines supervised and unsupervised methods for the reconstruction of geometric models with architectural information from unordered 3D data. Our method uses a downsampling strategy to enrich features to provide

Geometrical defect detection for additive manufacturing with machine learning models

open access: yesMaterials & Design, 2021
This study proposed a scheme based on Machine Learning (ML) models to detect geometric defects of additively manufactured objects. The ML models are trained with synthetic 3D point clouds with defects and then applied to detect defects in actual ...

Sewing Thread Consumption for Different Lockstitches of Class 300 Using Geometrical and Multi-Linear Regression Models

open access: yesAUTEX Research Journal, 2020
This paper aims to provide rapid and precise methods to allow industrials to predict the amount of sewing thread needed to sew a garment using different lockstitches of class 300 (301, 301/301, 304, 308, 309, 310, 311, 312, and 315).

Geometric models of matter [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Inspired by soliton models, we propose a description of static particles in terms of Riemannian 4-manifolds with self-dual Weyl tensor. For electrically charged particles, the 4-manifolds are non-compact and asymptotically fibred by circles over physical 3-space.

Mathematical models of the electric arc of variable geometrical parameters based on static voltage-current characteristics [PDF]

open access: yesE3S Web of Conferences, 2019
The paper presents the Schellhase and Pentegov models utilizing static voltage-current characteristics for representing processes occurring in the electric arc. In the approximations of these characteristics variation in geometrical parameters, i.e.

GEOMETRICAL MODELS OF MANDIBLE FRACTURE AND PLATE IMPLANT

open access: yesFacta Universitatis. Series: Mechanical Engineering, 2018
In the oral and maxillofacial surgery, there is a requirement to provide the best possible treatment for the patient with mandibular fractures. This treatment presumes application of reduction and fixation techniques for proper stabilization of the ...

Geometric Model of the Generations [PDF]

open access: yesPhysical Review Letters, 1995
We propose a geometric theory of flavor based on the discrete group ({ital S}{sub 3}){sup 3}, in the context of the minimal supersymmetric standard model. The group treats three objects symmetrically, while making fundamental distinctions between the generations.

Virtual Laser Scanning Approach to Assessing Impact of Geometric Inaccuracy on 3D Plant Traits

open access: yesRemote Sensing, 2022
In recent years, 3D imaging became an increasingly popular screening modality for high-throughput plant phenotyping. The 3D scans provide a rich source of information about architectural plant organization which cannot always be derived from multi-view ...
