Evaluation of Harmonics Impact on Digital Relays
(MDPI, 2018-04-11)
This paper presents the concept of the impact of harmonic distortion on a digital protection relay. The aim is to verify and determine the reasons of a mal-trip or failure to trip the protection relays; the suggested ...
The definition of input parameters for modelling of energetic subsystems
(EDP Sciences, 2013-06-26)
This paper is a short review and a basic description of mathematical models of renewable energy sources which present individual investigated subsystems of a system created in Matlab/Simulink. It solves the physical and ...
New experimental research stand SVICKA neutron field analysis using neutron activation detector technique
(EDP Sciences - France, 2018-04-18)
Knowledge of neutron energy spectra is very important because neutrons with various energies have a different material impact or a biological tissue impact. This paper presents basic results of the neutron flux distribution ...
The Application of Curve Fitting on the Voltammograms of Various Isoforms of Metallothioneins–Metal Complexes
(MDPI, 2017-03-01)
The translation of metallothioneins (MTs) is one of the defense strategies by which organisms protect themselves from metal-induced toxicity. MTs belong to a family of proteins comprising MT-1, MT-2, MT-3, and MT-4 classes, ...
New class of chaotic systems with circular equilibrium
(2015-04-10)
This paper brings a new mathematical model of the third-order autonomous deterministic dynamical system with associated chaotic motion. Its unique property lies in the existence of circular equilibrium which was not, by ...
