Concomitant extraction of natural stone blocks in a crushed stone quarry
Технічна інженерія, 2022 Most crushed granite quarries in Ukraine have areas with low fracturing, which allows mining blocks of natural decorative stone, and in some quarries these areas are significant in volume, for example, as in the Leznikovskyi quarry.

A note on entanglement classification for tripartite mixed states
Acta Polytechnica, 2022 We study the classification of entanglement in tripartite systems by using Bell-type inequalities and principal basis. By using Bell unctions and the generalized three dimensional Pauli operators, we present a set of Bell inequalities which classifies ...

Killing Tensor and Carter Constant for Painlevé–Gullstrand Form of Lense–Thirring Spacetime
Universe, 2021 Recently, the authors have formulated and explored a novel Painlevé–Gullstrand variant of the Lense–Thirring spacetime, which has some particularly elegant features, including unit-lapse, intrinsically flat spatial 3-slices, and some particularly simple ...

An Operational Characterization of Soft Topologies by Crisp Topologies
Mathematics, 2021 This paper contributes to the expanding literature on soft topology. We first prove that soft topologies can be characterized by crisp topologies. This takes advantage of two connected constructions that produce soft topologies from crisp topologies and ...

A Double Penalty Model for Ensemble Learning
Mathematics, 2022 Modern statistical learning techniques often include learning ensembles, for which the combination of multiple separate prediction procedures (ensemble components) can improve prediction accuracy.

Equivalence of the Frame and Halting Problems
Algorithms, 2020 The open-domain Frame Problem is the problem of determining what features of an open task environment need to be updated following an action. Here we prove that the open-domain Frame Problem is equivalent to the Halting Problem and is therefore ...

Three-Factor Kinetic Equation of Catalyst Deactivation
Entropy, 2021 The three-factor kinetic equation of catalyst deactivation was obtained in terms of apparent kinetic parameters. The three factors correspond to the main cycle with a linear, detailed mechanism regarding the catalytic intermediates, a cycle of reversible

Separability Criteria Based on the Weyl Operators
Entropy, 2022 Entanglement as a vital resource for information processing can be described by special properties of the quantum state. Using the well-known Weyl basis we propose a new Bloch decomposition of the quantum state and study its separability problem.
