The definition of open bisimilarity on the χ-processes does not give rise to a sensible relation on the χ-processes with the mismatch operator. The paper proposes ground open congruence as a principal open congruence on the χ-processes with the mismatch operator. The algebraic properties of the ground congruence is studied. The paper also takes a close look at barbed congruence. This relation i...

in this paper, we define the notions of fuzzy congruence relations and fuzzy convex subalgebras on a commutative residuated lattice and we obtain some related results. in particular, we will show that there exists a one to one correspondence between the set of all fuzzy congruence relations and the set of all fuzzy convex subalgebras on a commutative residuated lattice. then we study fuzzy...

The relationship between phylogenetic accuracy and congruence between data partitions collected from the same taxa was explored for mitochondrial DNA sequences from two well-supported vertebrate phylogenies. An iterative procedure was adopted whereby accuracy, phylogenetic signal, and congruence were measured before and after modifying a simple reconstruction model, equally weighted parsimony. ...

Flat iteration is a variation on the original binary version of the Kleene star operation P Q, obtained by restricting the rst argument to be a sum of atomic actions. It generalizes pre x iteration, in which the rst argument is a single action. Complete nite equational axiomatizations are given for ve notions of bisimulation congruence over basic CCS with at iteration, viz. strong congruence, b...

the aim of the present research was to investigate the relationship between the components of organizational intelligence and organizational culture in physical education general office and offices in east azerbaijan province. the present research was a descriptive – correlation one and performed as a field. the statistical population consisted of the staff of physical education general office ...

Nearly twenty years ago, two of the authors wrote a paper on congruence lattices of semilattices [9]. The problem of finding a really useful characterization of congruence lattices of finite semilattices seemed too hard for us, so we went on to other things. Thus when Steve Seif asked one of us at the October 1990 meeting of the AMS in Amherst what we had learned in the meantime, the answer was...
