Homogeneous Cosmological Models in Weyl’s Geometrical Scalar–Tensor Theory

open access: yesUniverse, 2023
In this paper, we consider homogeneous cosmological solutions in the context of the Weyl geometrical scalar–tensor theory. Firstly, we exhibit an anisotropic Kasner type solution taking advantage of some similarities between this theory and the Brans ...

Sewing Thread Consumption for Chain Stitches of Class 400 using Geometrical and Multilinear Regression Models

open access: yesAUTEX Research Journal, 2021
This work deals with determination of rapid and precise methods to predict the amount of sewing thread needed to sew a garment using different chain stitches of the class 400 (from 401 to 407 chain stitches).

GEOMETRICAL MODELS FOR OPTIMUM SHAPE OF CONCRETE ARCH DAMS [PDF]

open access: yesمجله مدل سازی در مهندسی, 2010
Concrete arch dams required less volume of concrete, when they are designed by an optimized geometrical model. These types of structures have better resistance against earthquakes because they are light, and can be built with lower prices.

Uq(sl3) web models: Locality, phase diagram and geometrical defects

open access: yesNuclear Physics B, 2022
We continue investigating the generalisations of geometrical statistical models introduced in [13], in the form of models of webs on the hexagonal lattice H having a Uq(sln) quantum group symmetry.

Geometrical Models for Substitutions [PDF]

open access: yesExperimental Mathematics, 2011
We consider a substitution associated with the Arnoux-Yoccoz interval exchange transformation (IET) related to the tribonacci substitution. We construct the so-called stepped lines associated with the fixed points of the substitution in the abelianization (symbolic) space. We analyze various projections of the stepped line, recovering the Rauzy fractal,

Implementing Data-Driven Approach for Modelling Ultrasonic Wave Propagation Using Spatio-Temporal Deep Learning (SDL)

open access: yesApplied Sciences, 2022
In this paper, we proposed a data-driven spatio-temporal deep learning (SDL) model, to simulate forward and reflected ultrasonic wave propagation in the 2D geometrical domain, by implementing the convolutional long short-term memory (ConvLSTM) algorithm.

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

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).

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 ...
