Rapid evaluation of maintenance process using statistical process control and simulation
(Daaam International Vienna, Vienna, 2018)
There are successful and less successful maintenance systems (MS). As a dynamic category, the success of the maintenance function must be taken into consideration both for the present day and the future. This is the reason ...
Enhanced matrix function approximation
(Kent State University, 2017)
Matrix functions of the form f (A) v, where A is a large symmetric matrix, f is a function, and v not equal 0 is a vector, are commonly approximated by first applying a few, say n, steps of the symmetric Lanczos process ...
Reliability Estimation of Stochastic Dynamical Systems with Fractional Order PID Controller
(World Scientific Publ Co Pte Ltd, Singapore, 2018)
In this paper, the reliability of stochastic dynamical systems under Gaussian white noise excitations with fractional order proportional-inegral-derivative (FOPID) controller is estimated. First, the FOPID controller is ...
Exploring innovative solutions for aged concrete utilization: treatment of liquid radioactive waste
(Springer, New York, 2018)
In this study, the applicability of waste concrete as a sorbent material for the liquid radioactive waste management was considered. The sample was properly characterized in terms of mineralogical and surface composition, ...
Improved TGA-MS measurements for evolved gas analysis (EGA) during pyrolysis process of various biomass feedstocks. Syngas energy balance determination
(Elsevier, Amsterdam, 2021)
This paper provides in-depth knowledge about the evolved gas analysis interpretation via newly proposed semi-quantitative approach, arising from thermogravimetric analysis (TGA) - mass spectrometry (MS) coupled measurements, ...
Error Estimates for Certain Cubature Formulae
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2018)
We estimate the errors of selected cubature formulae constructed by the product of Gauss quadrature rules. The cases of multiple and (hyper-)surface integrals over n-dimensional cube, simplex, sphere and ball are considered. ...
An Improved Techno-Economic Approach to Determination of More Precise Installed Parameter for Small Hydropower Plants
(MDPI, Basel, 2021)
Designing a small hydropower plant (SHPP) necessitates fulfillment of energy and ecological constraints, so a well-defined design flow is of the utmost significance. The main parameters of each SHPP are determined by ...
Numerical research of the compressible flow in a vortex tube using openfoam software
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The work presented in this paper is dealing with numerical simulation of energy separation mechanism and flow phenomena within a Ranque-Hilsch vortex tube. Simulation of turbulent, compressible, highly swirling flow inside ...
An experimental investigation and statistical analysis of turbulent swirl flow in a straight pipe
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper presents results of our own velocity field measurements in a straight pipe swirl flow. These studies were conducted using an originally designed hot wire probe. Due to the specially tailored shape of the probe, ...
A model for evaluation of customer satisfaction with banking service quality in an uncertain environment
(Routledge Journals, Taylor & Francis Ltd, Abingdon, 2018)
The aim of this study was to propose a fuzzy decision-making model to evaluate customer satisfaction level which has a critical effect on the bank's competitive advantage and its business. Value of customer satisfaction ...
