Optimal Placement and Sizing of Inverter-Based Distributed Generation Units and Shunt Capacitors in Distorted Distribution Systems Using a Hybrid Phasor Particle Swarm Optimization and Gravitational Search Algorithm
(Electric Power Components and Systems, 2020-08)
In this paper, a novel hybrid population-based meta-heuristic algorithm, called the hybrid Phasor Particle Swarm Optimization and Gravitational Search Algorithm (PPSOGSA), is proposed to solve the problem of optimal placement ...
Satisfaction is a function of users of logistics services in e-commerce
(Technology Analysis & Strategic Management, 2020-12)
Customer satisfaction in e-commerce directly depends on diverse dimensions of logistics services. In the market, there is a constant dilemma which logistics service dimensions affect customer satisfaction in e-commerce. ...
Evaluation of acid mine drainage kinetics in the lead-zinc mine
(Arabian Journal of Geosciences, 2020-05)
In this paper the comparative results of on-site analysis and modelling of the mechanisms and kinetics of the mining waters in the ore deposit Crnac are presented. The research process included hydrogeology explorations ...
Assessment of Probability of Gear Tooth Side Wear of a Planetary Gearbox
(TEHNIČKI VJESNIK-TECHNICAL GAZETTE, 2020-04)
Gear tooth side wear in planetary gearboxes represents one of the main reasons for damage occurring in these gears. Wear magnitude is unpredictable and depends on temperature, lubrication, load, material and other random ...
Nonlinear superharmonic resonance analysis of a nonlocal beam on a fractional visco-Pasternak foundation
(Proceedings of the Institution of Mechanical Engineers. Part C: Journal of Mechanical Engineering Science, 2020-07)
This paper investigates the dynamic behaviour of a geometrically nonlinear nanobeam resting on
the fractional visco-Pasternak foundation and subjected to dynamic axial and transverse loads. The
fractional-order governing ...
First cobalt complexes with methyl pyruvate semi/thiosemicarbazone - synthesis, physico-chemical and structural characterization
(Journal of the Serbian Chemical Society, 2020)
In the reaction of acetone solutions of CoX2∙nH2O (X = Cl, Br) with methyl pyruvate semi/thiosemicarbazone (Hmps, Hmpt) the first Co(II) complexes with these ligands, i.e., [Co(Hmps)(H2O)X2] (X = Cl (1), Br (2)), ...
Performance Analysis of an IEEE 802.15.4 Network Operating Under κ–μ Fading, Interference and AWGN
(Iranian Journal of Science and Technology - Transactions of Electrical Engineering, 2020-03)
IEEE 802.15.4 standard is widely used in the field of low-power, low-cost and low-bit rate communications. In this paper, we analyze performance of an IEEE 802.15.4 network operating in 2450 MHz ISM (Industry, Science and ...
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 ...
