A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Local convergence of Newton's method using Kantorovich convex majorants

open access: yesJournal of Numerical Analysis and Approximation Theory, 2010
We are concerned with the problem of approximating a solution of an operator equation using Newton's method. Recently in the elegant work by Ferreira and Svaiter [6] a semilocal convergence analysis was provided which makes clear the relationship of the

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Local Convergence of Newton’s Method on Lie Groups and Uniqueness Balls

open access: yesAbstract and Applied Analysis, 2013
An estimation of uniqueness ball of a zero point of a mapping on Lie group is established. Furthermore, we obtain a unified estimation of radius of convergence ball of Newton’s method on Lie groups under a generalized L-average Lipschitz condition.

An Explicit Constitutive Reconstruction Framework for Mechanical Characterization of Miniaturized 3D‐Printed Specimens

open access: yesAdvanced Engineering Materials, EarlyView.
An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...

Estimation of the velocity vector of moving targets from SAR images [PDF]

open access: yes, 2008
Il SAR (Synthetic Aperture Radar) è un tipo di radar che acquisisce immagini per sintesi con alta risoluzione e indipendentemente dalle condizioni meteorologiche e di luminosità; per queste ragioni il SAR ricopre un ruolo fondamentale nel telerilevamento

Weak convergence and the Prokhorov radius

open access: yesJournal of Mathematical Analysis and Applications, 1992
The Prokhorov radius \(D(a,b,t,s)\) is defined as the supremum of the Prokhorov (Ky Fan) distance \[ d(X,a)=\inf\{r>0,\;\text{Pr}(| X- a|>r)
