Modular Lattice Generated by Fuzzy Implicationl

open access: yes, 2016
Background Objective: Lattice has been used in mathematics in 18th century. Modular lattice is one of the most important types of lattice. In18 Michal and Drewniak define a lattice which is generated by fuzzy implication.

Weak Relative Complements in Almost Distributive Lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
In this paper, the concept of relative complementation in almost distributive lattice is generalized. We obtain several properties on the sets of weak relative complement elements.

f-Fixed Points of Isotone f-Derivations on a Lattice

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
In a recent paper, Çeven and Öztürk have generalized the notion of derivation on a lattice to f-derivation, where f is a given function of that lattice into itself.

Simulation results and applications of an advection bounded scheme to practical flows

open access: yes, 2012
This paper reports experiments on the use of a recently introduced advection bounded upwinding scheme, namely TOPUS (Computers & Fluids 57 (2012) 208-224), for flows of practical interest.

Rowmotion on \(m\)-Tamari and biCambrian lattices [PDF]

open access: yes
Thomas and Williams conjectured that rowmotion acting on the rational \((a,b)\)-Tamari lattice has order \(a+b-1\). We construct an equivariant bijection that proves this conjecture when \(a\equiv 1\pmod b\); in fact, we determine the entire orbit ...

Congruences and Trajectories in Planar Semimodular Lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
A 1955 result of J. Jakubík states that for the prime intervals p and q of a finite lattice, con(p) ≥ con(q) iff p is congruence-projective to q (via intervals of arbitrary size).

The prime filter theorem of lattice implication algebras

open access: yes, 2001
Using a special set x −1 F , we give an equivalent condition for a filter to be prime, and applying this result, we provide the prime filter theorem in lattice implication algebras. 2000 Mathematics Subject Classification. Primary 03G10, 06B10, 54E15. 1.

Active-set strategy in Powell's method for optimization without derivatives [PDF]

open access: yes, 2014
In this article we present an algorithm for solving bound constrained optimization problems without derivatives based on Powell's method for derivative-free optimization. First we consider the unconstrained optimization problem.

Numerical solution of coupled mass and energy balances during osmotic microwave dehydration

open access: yes, 2012
The mass and energy transfer during osmotic microwave drying (OD-MWD) process was studied theoretically by modeling and numerical simulation. With the aim to describe the transport phenomena that occurs during the combined dehydration process, the mass ...
