The problem of the existence of analytically definable well-orderings at a given level of the projective hierarchy is considered. This problem is important as a part of the general problem of the study of the projective hierarchy in the ongoing devel

The design techniques of integrated information systems development aimed at the life cycle support are reviewed. Cases of the CALS-technologies and systems engineering for building some typical models are considered. These models can be used for typ

Examples of effectively indiscernible projective sets of real numbers in various models of set theory are presented. We prove that it is true, in Miller and Laver generic extensions of the constructible universe, that there exists a lightface Π21 eq

In this study, optimization based on artificial neural network (ANN) was established to predict the optimal performance parameters of the system, leading to an optimized propulsion system. Optimization related works on propulsion system investigated

In this paper we prove that for any m≥1 there exists a generic extension of L, the constructible universe, in which it is true that the set of all constructible reals (here subsets of ω) is equal to the set D1m of all reals definable by a paramete

In this paper, we prove the following. If n≥3, then there is a generic extension of L, the constructible universe, in which it is true that the set P(ω)∩L of all constructible reals (here—subsets of ω) is equal to the set P(ω)∩Δn1 of all

Models of set theory are defined, in which nonconstructible reals first appear on a given level of the projective hierarchy. Our main results are as follows. Suppose that n ≥ 2 . Then: 1. If it holds in the constructible universe L that a ⊆ ω an

The energy demand worldwide is increasing, and such demand should be satisfied with renewable resources to diminish the carbon footprint. There are a few ways to produce clean energy such as wind, solar and marine energy; however, some technologies a
