Sustainable Greenhouse Covering Materials with Nano- and Micro-Particle Additives for Enhanced Radiometric and Thermal Properties and Performance

open access: yesAgriEngineering, 2023
This review aims to provide a comprehensive overview of nano- and microscopic materials that can provide thermal radiation insulation without reducing visible light transmittance, thereby reducing heat loss and conserving energy in greenhouses.

Covering properties in neutrosophic topological spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
Single-valued neutrosophic set is being extensively used in solving real-life problems. Recently neutrosophic topological space was developed based on redefined single-valued neutrosophic set operations. The purpose of this article is to investigate some

Effect of Colloid Water Thickness on Microstructures and Mechanical Properties of Titanium/Steel Interfaces Prepared by Explosive Welding [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
Using colloid water as a covering for explosives can improve the energy efficiency for explosive welding, while its effects on bonding properties remain unclear.

On Fuzzy C-Paracompact Topological Spaces

open access: yesMathematics, 2022
The aim of this paper is to study fuzzy extensions of some covering properties defined by A. V. Arhangel’skii and studied by other authors. Indeed, in 2016, A. V.

Single-Valued Neutrosophic Covering-Based Rough Set Model Over Two Universes and Its Application in MCDM [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This article aims to propose a new type of single-valued neutrosophic(SVN) covering-based rough sets over two universes by using Wang’s single-valued neutrosophic covering rough sets.

Some properties defined by relative versions of star-covering properties II

open access: yesApplied General Topology, 2023
In this paper we consider some recent relative versions of Menger property called set strongly star Menger and set star Menger properties and the corresponding Hurewicz-type properties. In particular, using [2], we "easily" prove that the set strong star

The Jensen Covering Property [PDF]

open access: yesJournal of Symbolic Logic, 2001
The Jensen covering lemma says that either L has a club class of indiscernibles, or else, for every uncountable set A of ordinals, there is a set B ∈ L with A ⊆ B and card (B) = card(A). One might hope to extend Jensen's covering lemma to richer core models, which for us will mean to inner models of the form L[] where is a coherent sequence of ...

More on Selective Covering Properties in Bitopological Spaces

open access: yesJournal of Mathematics, 2021
In this study, we continue our investigation of selective covering properties in bitopological spaces. We discuss their behaviour under certain kinds of mappings.

The use of artificial neural networks for mathematical modeling of the effect of composition and production conditions on the properties of PVC floor coverings [PDF]

open access: yesHemijska Industrija, 2017
The application of PVC floor coverings is strongly connected with their end-use properties, which depend on the composition and processing conditions.

Selection principles and covering properties in bitopological spaces

open access: yesApplied General Topology, 2020
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,
