In this paper I will attempt to characterise the difference between ontological and non-ontological categories for the sake of a better understanding of the subject matter of ontology. My account of ontological categories defines them as equivalence classes of a certain family of equivalence relations that are determined by ontological relations. As a result, the demarcation problem for ontolog...

In this paper, we introduce and study fuzzy variational-like inclusion, fuzzy resolvent equation and $H(cdot,cdot)$-$phi$-$eta$-accretive operator in real  uniformly smooth Banach spaces. It is established that fuzzy variational-like inclusion is equivalent to a fixed point problem as well as to a fuzzy resolvent equation. This equivalence is used to define an iterative algorithm for solving fu...

In order to study quantum aspects of σ-models related by Poisson–Lie T-duality, we construct three-and two-dimensional models that correspond, in one of the dual faces, to deformations of S 3 and S 2. Their classical canonical equivalence is demonstrated by means of a generating functional, which we explicitly compute. We examine how they behave under the renormalization group and show that dua...

However, this problem can be fixed by requiring active substitutions be defined on the base sort only (see, for instance, [2]). The purpose of this note is to supply a proof for the theorem. In the original semantics in [1], the use of structural equivalence introduces the nondeterminism, which makes it difficult to write a rigorous proof. To overcome the difficulty we shall use intermediate se...

in this work, the feasibility study for design of a laboratory sample rde which has an annular geometry with diameter of 76 mm and length of 101 mm has been performed. detonation engines are expected to be used as propulsion system in aerospace applications in the future. several types of detonation engines are currently under examination, including the rotating detonation engine (rde). first, ...
