Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

GELİŞTİRİLMİŞ KALİTE KARŞILAŞTIRMA METODUYLA HİDROLİK KAZICI MAKİNE SEÇİMİ
Pamukkale University Journal of Engineering Sciences, 1999 Quality comparison equipment selection is essentially an equipment ranking method developed by Cokorilo and Milicic in 1991. The concept of this method is based on three matrixes models which are namely called as the machine technical characteristic ...

Left Ideal Preserving Maps on Triangular Algebras [PDF]
, 2018 Let A be a unital algebra over a commutative unital ring R. We say that A is a SLIP algebra if every R-linear map on A that leaves invariant every left ideal of A is a left multiplier. In this paper we study whether a triangular algebra Tri(A,M,B) is a SLIP algebra and give some necessary or sufficient conditions for a triangular algebra be a SLIP ...

Waring problem for triangular matrix algebra
Linear Algebra and its ApplicationsThe Matrix Waring problem is if we can write every matrix as a sum of $k$-th powers. Here, we look at the same problem for triangular matrix algebra $T_n(\mathbb{F}_q)$ consisting of upper triangular matrices over a finite field. We prove that for all integers $k, n \geq 1$, there exists a constant $\mathcal C(k, n)$, such that for all $q> \mathcal ...

Triangular matrix and Koszul algebras [PDF]
International Journal of Algebra, 2007 It is well known that Koszul algebras are quadratic and monomial quadratic algebras [7] and quadratic algebras of global dimension two are Koszul. It was also proved in [4] that algebras with a quadratic Groebner basis are Koszul, however there is no general characterization of Koszul algebras, hence it is of interest to construct new Koszul algebras ...

Advanced Engineering Materials, EarlyView.Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Gorenstein defect categories of triangular matrix algebras [PDF]
arXiv, 2014 We apply the technique of recollement to study the Gorenstein defect categories of triangular matrix algebras. First, we construct a left recollement of Gorenstein defect categories for a triangular matrix algebra under some conditions, using it, we give a categorical interpretation of the Gorenstein properties of the triangular matrix algebra obtained

Advanced Engineering Materials, EarlyView.This study explores geometry‐driven phase evolution in gyroid shell metamaterials made via laser powder bed fusion of 17‐4 precipitation hardened stainless steel. Locally hardened regions develop along the primary loading paths in the structure, which finite element analysis and geometric considerations link to enhanced gyroid strength.

An Application of the t-Extension of the p-Fibonacci Pascal Matrix in Coding Theory
Advances in Mathematical Physics, 2022 We consider the t-extension of the p-Fibonacci Pascal matrix. First, we study the k-th power of the t-extension of the p-Fibonacci lower and upper triangular Pascal matrix.
