Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

How do both firm‐level resources and country‐level competitiveness shape the relationship between alliance portfolio diversity and radical innovation? A comparison between the food and other manufacturing industries

open access: yesAgribusiness, EarlyView.
Abstract This study examines how European food companies can operationally leverage the value created by strategic alliances into commercially viable products. More importantly, it emphasizes that the effects of alliance portfolio diversity (APD) on radical innovation performance can be achieved not only directly, but also via moderating roles, that is,

On semigroups of relations with the operation of the rectangular product [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
A set of binary relations closed with respect to some collection of operations on relations forms an algebra called an algebra of relations. The theory of algebras of relations is an essential part of modern algebraic logic and has numerous applications ...

On the Structure of Acyclic Binary Relations

open access: yes, 2018
We investigate the structure of acyclic binary relations from different points of view. On the one hand, given a nonempty set we study real-valued bivariate maps that satisfy suitable functional equations, in a way that their associated binary relation is acyclic. On the other hand, we consider acyclic directed graphs as well as their representation by

Groups of binary relations

open access: yesSemigroup Forum, 1970
It was shown in [3] that every finite group is the maximal subgroup of a semigroupBx of all binary relations on some finite set X. This result is extended here to arbitrary groups.
