The Design and Simulation of an Astronomical Clock
(MDPI, Basel, 2021)
This paper describes and explains the synthesis of an astronomical clock mechanism which displays the mean position of the Sun, the Moon, the lunar node and zodiac circle as well as the Moon phases and their motion during ...
Some New Observations for F-Contractions in Vector-Valued Metric Spaces of Perov's Type
(MDPI, Basel, 2021)
The main purpose of this article is to improve, generalize and complement some recently established results for Perov's type F-contractions. In our approach, we use only the property (F1) of Wardowski while other authors ...
Numerical-experimental determination of stress and deformation state in connection lugs
(Institut za ispitivanje materijala, Beograd, 2021)
The present paper describes the numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. Research is based on structural elements of ...
Brownian fractal nature coronavirus motion
(World Scientific Publ Co Pte Ltd, Singapore, 2021)
The goal of our research is to establish the direction of coronavirus chaotic motion to control corona dynamic by fractal nature analysis. These microorganisms attaching the different cells and organs in the human body ...
Intact stability of historic passenger ships in light of the second generation intact stability criteria
(Royal Inst Naval Architects, London, 2021)
The paper examines the intact stability of historic passenger ships from the point of view of the contemporary-notion of the intact stability. i.e. the Second Generation Intact Stability Criteria (SGISC) framework. Au ...
Experimental research of absorption properties of rigid foam filled circular seamless tube energy absorber under quasi-static axial load
(Sage Publications Ltd, London, 2021)
The aim of this research work is investigations of absorption characteristics of a circular seamless tube collision absorber filled by rigid polyurethane (PU) foam under axial load. Shrinking of circular tube passing through ...
Napredni model upravljanja energijom zasnovan na pravilima za poboljšanje ekonomičnosti hibridnih električnih guseničnih vozila / Advanced rule-based energy management for better fuel economy of hybrid electric tracked vehicle
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2021)
Sva nedavna tehnološka dostignuća na polju raspodele snage između pogonskih agregata u hibridnim guseničnim vozilima su uglavnom teško primenjiva i teška za izračunavanje što ih čini nepraktičnim za primenu u stvarnom ...
Some significant remarks on multivalued Perov type contractions on cone metric spaces with a directed graph
(Amer Inst Mathematical Sciences-Aims, Springfield, 2021)
Using the approach of so-called c-sequences introduced by the fifth author in his recent work, we give much simpler and shorter proofs of multivalued Perov's type results with respect to the ones presented in the recently ...
Modelling and analysis of machine tool with parallel-serial kinematics based on O-X glide mechanism
(Springer Heidelberg, Heidelberg, 2021)
Machine tools with a parallel-serial (hybrid) kinematics structures represent a compromise solution that combines the advantages of traditional serial and parallel kinematic in the building of machine tools. By selecting ...
Thermogravimetric and kinetic analysis of biomass and polyurethane foam mixtures Co-Pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Alternative fuels are crucial for the decarbonisation of high-energy demanding processes. The utilisation of waste materials to produce alternative fuels is especially interesting since, the co-pyrolysis of waste plastics ...
