Advanced 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
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 ...

Advanced 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]
Computer Science Journal of MoldovaThe 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
Journal 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})\

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Hamming distance from irreducible polynomials over $\mathbb {F}_2$ [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 We study the Hamming distance from polynomials to classes of polynomials that share certain properties of irreducible polynomials. The results give insight into whether or not irreducible polynomials can be effectively modeled by these more general ...
