Theoretical Study of Tool Holder Self-excited Oscillation in Turning Processes Using a Nonlinear Model
(International Journal of Acoustics and Vibration, 2018)
In this paper, by observing a system which is composed from a workpiece and a tool holder, a dynamic and a
mathematical nonlinear model is acquired. These models can be used as a theoretical foundation for research ...
Concept of reconstruction and modernization of railway tracks of route 9a – doboj-tuzla-brčko section
(CETRA- 5th International Conference on Road and Rail Infrastructure, 2018-05)
War developments in the mid-1990s, economic crisis and the lack of funds to reconstruct
railway infrastructure and the fleet have led to the situation that railway traffic in Bosnia
and Hercegovina (BiH) goes at low ...
Design of IIR Multiple-Notch Filters with Symmetric Magnitude Responses About Notch Frequencies
(Circuits, Systems, and Signal Processing, 2018-05)
A novel all-pass-based infinite impulse response (IIR) digital multiple-notch filter design method is presented in this paper. The proposed method ensures that, for an arbitrary pass-bands ripple value, specifications ...
Application of the Fokker-Planck Kolmogorov equation to determining the mean value of nucleons generated by the direct ejection process
(Nuclear Technology and Radiation Protection, 2019)
The statistical description of the process of direct nucleon ejection is the subject of this paper. This description is based on the generalized Fokker-Planck-Kolmogorov equation. The basic proposal is this: deterministic ...
OPTIMIZATION OF ULTRASONICALLY ASSISTED ADSORPTION OF Cu(II) ON CARBONIZED AND ACTIVATED WALNUT SHELLS
(Facta Universitatis Series Working and Living Environmental Protection, 2018-11)
The effects of ultrasound (US) on the adsorption process of Cu(II) on granulated activated carbon (GAC), produced by walnut shells, was studied in this paper. Equilibrium results of the adsorption process are tested by ...
Ultrasound-assisted extraction of sunflower oil from the cake after sunflower seed pressing
(Journal of Agricultural Sciences, 2018)
The influence of ultrasound application on the extraction (UE) of the cake after sunflower seed pressing was studied. Three different solvents were used for extraction in the Soxhlet apparatus: n-hexane, petroleum ether ...
New Eco-Friendly Xanthate-Based Flotation Agents
(Minerals, 2020-04)
An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as ...
An analysis of energy efficiency in Wireless Sensor Networks (WSNs) applied in smart agriculture
(Computers and Electronics in Agriculture, 2019-01)
In this paper the usage of Wireless Sensor Networks (WSN) in smart agriculture applications was analyzed. The main focus of the paper is on the power consumption of the various WSN components, on the both levels, physical ...
Experimental and numerical study of temperature field during hard facing of different carbon steels
(Thermal Science, 2020)
In this research the 3-D transient non-linear thermal analysis of the hard-facing process was performed by using the experimental testing and finite element method. Testing was done at three different carbon steels and the ...
Optimization and kinetic modeling of waste lard methanolysis in a continuous reciprocating plate reactor
(Chinese Journal of Chemical Engineering, 2019-10)
Continuous biodiesel production from a waste pig-roasting lard, methanol and KOH was carried out in a reciprocating plate reactor (RPR) using a factorial design containing three process factors, namely methanol/lard molar ...
