Multipurpose compensation scheme for voltage Sag/swell and selective harmonics elimination in distribution systems
(VSB-Technical University of Ostrava, 2018)
Voltage harmonics, sag, and swell are the most harmful disturbances in distribution systems. This paper introduces a novel effective controller method for simultaneous compensation of both voltage sag/swell and voltage ...
Octagonal Shaped Metamaterial Absorber Based Energy Harvester
(Kaunas University of Technology, 2018)
In this study, a novel octagonal shaped metamaterial based broadband absorber is proposed for energy harvesting at WIMAX wireless communication band. The proposal has an absorption of 99.97 % at 5.5 GHz with a bandwidth ...
Apostol type (P, Q)-Frobenius-euler polynomials and numbers
(University of Kragujevac, Faculty of Science, 2018)
In the present paper, we introduce (p, q)-extension of Apostol type Frobenius-Euler polynomials and numbers and investigate some basic identities and properties for these polynomials and numbers, including addition theorems, ...
Climate impacts in Europe under+1.5 degrees C global warming
(John Wiley and Sons Inc, 2018)
The Paris Agreement of the United Nations Framework Convention on Climate Change aims not only at avoiding +2 degrees C warming (and even limit the temperature increase further to +1.5 degrees C), but also sets long-term ...
Traffic Safety at Median Ditches: Steel vs. Concrete Barrier Performance Comparison Using Computer Simulation
(Mdpi, 2018)
In Turkey, concrete V-shaped ditches are formed at the median section of divided highways to provide drainage. Recent accidents show that these ditches actually present safety risks to vehicles entering the medians. Vehicles ...
