This paper is written in the framework of the Special Issue of Mathematics entitled
“Hypercompositional Algebra and Applications”, and focuses on the presentation of the …

In this paper, we generalize three types of rough set models based on j-neighborhood space
(ie, type 1 j-neighborhood rough set, type 2 j-neighborhood rough set, and type 3 j …

In this paper, the notions of int-soft left (right) ideals, int-soft interior ideals and int-soft
biideals over the soft sets are introduced and several related properties of these notions are …

The various branches of Mathematics are not separated between themselves. On the
contrary, they interact and extend into each other's sometimes seemingly different and …

In this article we deal with field data modelling. The data have been recorded during the
operation of a drinking water distribution system. Numerous records about water distribution …

In this article we deal with modelling diagnostic data. They are the data measured during the
operation of a conveyor belt. To be specific, we observe how the distances between …

The purpose of this paper is the study of prime ideals and prime filters in hyperlattices. I−
filter and the filter generated by a∈ L are introduced. Moreover, we introduce dual …

Abstract System quality requirements are typically formed by consideration of reliability and
safety performance. Failures caused by system weakness, degradation or fatigue may cause …

When we assume that the input–set of an automaton without output is a semihypergroup
instead of a monoid, we talk about quasi–multiautomata. Even though cartesian composition …

In our paper, we construct Cartesian composition of automata in a way rather different from
the classical approach. In our case, the resulting structure is not an automaton but a quasi …
