Congruence lattices of free lattices in non-distributive varieties

open access: yes, 2005
We prove that for any free lattice F with at least $\aleph\_2$ generators in any non-distributive variety of lattices, there exists no sectionally complemented lattice L with congruence lattice isomorphic to the one of F.

A decomposition of distributive lattices

open access: yesDiscrete Mathematics, 1985
The author works out the concept of a split decomposition of a distributive lattice fitting into the general decomposition theory of Cunningham and Edmonds. He clarifies the amount of uniqueness valid for repeated decompositions, the structure of the building stones, and the reconstruction process.

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Representation of certain classes of distributive lattices by sections of sheaves

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
Epstein and Horn ([6]) proved that a Post algebra is always a P-algebra and in a P-algebra, prime ideals lie in disjoint maximal chains. In this paper it is shown that a P-algebra L is a Post algebra of order n≥2, if the prime ideals of L lie in disjoint

A uniform refinement property for congruence lattices

open access: yes, 2005
The Congruence Lattice Problem asks whether every algebraic distributive lattice is isomorphic to the congruence lattice of a lattice. It was hoped that a positive solution would follow from E. T. Schmidt's construction or from the approach of P. Pudlak,

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Algorithm for lattice model analyzing of information-measuring system structure

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
A lattice model of the structures of developing information-measuring systems is considered. It is shown that this model allows studying the transformation of structures of information-measuring system during the life cycle.

Soft Lattices

open access: yesJournal of New Results in Science, 2012
Soft set theory was introduced by Molodtsov in 1999 as a general mathematical tool for dealing with problems that contain uncertainity. In this paper,we define concept of a soft lattice, soft sublattice, complete soft lattice, modular soft lattice ...

Belief Functions on Distributive Lattices

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2013
The Dempster-Shafer theory of belief functions is an important approach to deal with uncertainty in AI.In the theory, belief functions are defined on Boolean algebras of events. In many applications of belief functions in real world problems, however, the objects that we manipulateis no more a Boolean algebra but a distributive ...
