An analytical model of the replacement costs of aircraft engine life-limited parts
(Emerald Group Publishing Ltd, Bingley, 2021)
Purpose The purpose of this paper is to present novel recursive expressions for modelling the replacement costs of aircraft engine life-limited parts during shop visits to assist engine operators in both evaluating their ...
Numerical Simulation of Aerodynamic Performance of Wing with Split Winglets
(Belgrade : Military Technical Institute, 2020)
Winglet is an additional surface in a form of vertical or horizontal extension of the wing. The shape of winglet changed during the development period and depending on the type of aircraft on which they were installed. Due ...
Development of a Coordinate Measuring Machine-Based Inspection Planning System for Industry 4.0
(MDPI, Basel, 2021)
Industry 4.0 represents a new paradigm which creates new requirements in the area of manufacturing and manufacturing metrology such as to reduce the cost of product, flexibility, mass customization, quality of product, ...
Vickers hardness indentation size effect in selective laser melted MS1 maraging steel
(Sage Publications Ltd, London, 2021)
In this paper, selective laser melting fabricated specimens in non-heat-treated and heat-treated conditions were subjected to Vickers microhardness testing, by using a full range of loadings: 10, 25, 50, 100, 200, 300, ...
Transport and mining machines operators’ behavioral attitudes in safety climate context
(Belgrade : Institute for research and design in Industry, 2022)
As industrial systems represent a complex socio-technical system, it is necessary to analyse the impact of manager-operator-machine interaction on industrial safety, as categories of contextual factors. However, modern ...
Assessment of integrity of pressure vessels for compressed air
(Institut za ispitivanje materijala, Beograd, 2021)
Fracture mechanics approach for structural integrity assessment is described in the case of pressure vessels for compressed air. The results of non-destructive testing indicated unacceptable defects on the vessels and set ...
Pyrolysis kinetics of [4-(hydroxymethyl)phenoxymethyl]polystyrene (Wang) resin using master-plot method and distributed reactivity model
(Springer, New York, 2022)
The pyrolysis of [4-(hydroxymethyl)phenoxymethyl]polystyrene (Wang) resin was studied by dynamic simultaneous thermogravimetric analysis (TGA) and derivative thermogravimetry techniques. The studied resin is used as the ...
A new optimisation method of PIDC controller under constraints on robustness and sensitivity to measurement noise using amplitude optimum principle
(Taylor & Francis Ltd, Abingdon, 2021)
This paper presents a new optimisation method for PID controller cascaded with a lead-lag compensator (PIDC). Parameters of the controller are obtained by solving the constrained optimisation problem. We propose two variants ...
On the Gauss-Kronrod quadrature formula for a modified weight function of Chebyshev type
(Springer, Dordrecht, 2022)
In this paper, we consider the Gauss-Kronrod quadrature formulas for a modified Chebyshev weight. Efficient estimates of the error of these Gauss-Kronrod formulae for analytic functions are obtained, using techniques of ...
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 ...
