A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Permutations from APN power functions over F22n

open access: yes网络与信息安全学报, 2017
APN functions have the lowest differential uniform over finite fields with characteristic 2 and the APN power functions are the most classical ones.APN power functions are all 3-1 functions over F22n.By generalizing the idea of changing 2-1 functions to ...

On the number of rational points on curves over finite fields with many automorphisms [PDF]

open access: yes, 2013
Using Weil descent, we give bounds for the number of rational points on two families of curves over finite fields with a large abelian group of automorphisms: Artin–Schreier curves of the form yq−y=f(x) with f∈Fqr[x], on which the additive group Fq acts,

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Vector finite fields of characteristic two as algebraic support of multivariate cryptography [PDF]

open access: yesComputer Science Journal of Moldova
The central issue of the development of the multivariate public key algorithms is the design of reversible non-linear mappings of $n$-dimensional vectors over a finite field, which can be represented in a form of a set of power polynomials. For the first

Algorithms for Exponentiation in Finite Fields

open access: yesJournal of Symbolic Computation, 2000
Let \(q\) be a prime power, and let \(r=nk+1\) be a prime not dividing \(q\). Let \(e\) be the index of the subgroup generated by \(q\) in the multiplicative group \(\mathbb Z ^*_r=\mathbb Z _r \setminus \{0\}\), and let \(K\) be the unique subgroup of order \(k\) in \(\mathbb Z ^*_r\). Let \(\beta\) be a primitive \(r\)th root of unity in GF\((q^{nk})\

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,

Quantum computing for finite fields. [PDF]

open access: yes, 2021
Finite fields, most notably GF(p) and GF(p^n), are mathematical objects with a wide variety of applications. With the advent of quantum computing, algorithms are being researched to provide speedups over classical computing for finite fields.
