A system of interaction and structure [PDF]

open access: yesACM Transactions on Computational Logic, 2007
This article introduces a logical system, called BV, which extends multiplicative linear logic by a noncommutative self-dual logical operator. This extension is particularly challenging for the sequent calculus, and so far, it is not achieved therein. It becomes very natural in a new formalism, called the calculus of structures

Multiaxial fatigue of cast aluminium EN AC-42000 T6 (G-AlSi7Mg0.3 T6) for automotive safety components under constant and variable amplitude loading [PDF]

open access: yesFracture and Structural Integrity, 2016
Regarding the fatigue behaviour of EN AC-42000 T6 (A 356 T6), which is the most frequently used cast aluminium alloy for automotive safety components, especially under non-proportional constant and variable normal and shear stress amplitudes with ...

Structural Transitions in a Classical Two-Dimensional Molecule System [PDF]

open access: yes, 2002
The ground state of a classical two-dimensional (2D) system with finite number of charged particles, trapped by two positive impurities charges localized at a distance (zo) from the 2D plane and separated from each other by a distance xp are obtained ...

THE STRUCTURE OF SPIN SYSTEMS

open access: yesInternational Journal of Mathematics, 2003
A spin system is a sequence of self-adjoint unitary operators U1, U2, … acting on a Hilbert space H which either commute or anticommute, UiUj = ±UjUi for all i, j; it is called irreducible when {U1, U2, …} is an irreducible set of operators. There is a unique infinite matrix (cij) with 0, 1 entries satisfying [Formula: see text] Every matrix (cij ...

Experimental and numerical analyses of stiffness and fatigue properties of a spring element for mounts with tunable stiffness made of C85S+QT sheet steel

open access: yesFracture and Structural Integrity
Mounting stiffness has an important impact on a system’s structural dynamics and also on the durability of many structures. Mounts with tunable stiffness allow adapting a system’s structural dynamic behavior.

Structural relaxation in a system of dumbbell molecules

open access: yes, 2002
The interaction-site-density-fluctuation correlators, the dipole-relaxation functions, and the mean-squared displacements of a system of symmetric dumbbells of fused hard spheres are calculated for two representative elongations of the molecules within ...
