Mobility of positive ions in CF4
(IOP Publishing Ltd, Bristol, 2014)
Cross-section sets for transport of positive ions in CF4 that fit the available experimental data for mobility are assessed by normalizing the available experimental and theoretical cross-sections within the framework of ...
Wheel-rail contact forces measurements using strain gauges applied on the rails
(Innovation Center of Faculty of Mechanical Engineering, Belgrade, 2019)
The paper presents practical application of originally developed method for wayside measurements of wheelrail contact forces using strain gauges and an overview of recently developed similar methods presented by different ...
Experimental determining of fracture behaviour of P460NL1 steel welded joint specimens
(Elsevier Science Bv, Amsterdam, 2019)
This paper is focused on the experimental measuring of impact energy as a part of the doctoral dissertation involving the fatigue behaviour of welded joints, made of fine grain normalised micro-alloyed low carbon high ...
Fractional order Cole model of bioimpedance of the human skin: new results
(Bulgaria: Publ. House „Vanio Nedkov“, 2012)
In this paper, electrical impedance measurement data and fractional calculus have been utilized for modeling bioimpedance properties of human skin. In relation to our experimental in vivo conditions,
structure and complexity ...
Conceptual design of solar-powered high-altitude long endurance aircraft
(University of Belgrade, Faculty of Mechanical Engineering, 2022)
The design of high-altitude unmanned aerial vehicles is one of the most current research
topics today in the field of aviation. The possible purposes of such flying platforms are

The Influence of NARX Control Parameters on the Fuel Efficiency Improvement of a Hydraulic Hybrid Powertrain System
(Faculty of Engineering, University of Kragujevac, 2022)
Multivariable fractional order PID control of the cryogenic process of mixing of two gaseous airs flows: D-decomposition method
(Belgrade : Serbian Society of MechanicsFaculty of Technical Sciences Novi Sad, 2016)
In the air production cryogenic liquid [1], the nowadays energy concern
and operation requirement can rather exploit the advances in control
systems theory to derive optimally designed closed-loop plants that
can operate ...
Comparison of Numerical Simulation Models for Open Loop Flight Simulations in the Human Centrifuge
(Wiley Online Library, 2013)
To achieve predefined Gz load profile in high G training in human centrifuge, it is necessary to determine angular velocity and acceleration of a planetary axis (centrifuge arm). Initial value problem that can not be ...
Overview of numerical methods for solving optimal control problem in guidance algorithms
(Univerzitet u Beogradu, Mašinski fakultet, 2022)
Numerical techniques for solving optimal control problems fall into two general classes: indirect methods and direct methods. In an indirect method, we rely on the Pontryagin's maximum principle and other necessary conditions ...
Design of small-scale composite vertical-axis wind turbine blade
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
Although less efficient than their horizontal-axis counterparts, vertical-axis wind turbines (VAWTs) present an interesting research topic as well as a renewable energy converter with lots of potential for application in ...
