On the Gauss-Kronrod quadrature formula for a modified weight function of Chebyshev type
(Springer, Dordrecht, 2022)
In this paper, we consider the Gauss-Kronrod quadrature formulas for a modified Chebyshev weight. Efficient estimates of the error of these Gauss-Kronrod formulae for analytic functions are obtained, using techniques of ...
A note on generalized averaged Gaussian formulas for a class of weight functions
(Springer, Dordrecht, 2020)
In the recent paper Notaris (Numer. Math., 142:129-147,2019) it has been introduced a new and useful class of nonnegative measures for which the well-known Gauss-Kronrod quadrature formulae coincide with the generalized ...
On d*-Complete Topological Spaces and Related Fixed Point Results
(MDPI, Basel, 2020)
In this paper, we introduce the concept ofd*-complete topological spaces, which include earlier defined classes of complete metric spaces and quasib-metric spaces. Further, we prove some fixed point results for mappings ...
Application of modified Kalina cycle in biomass chp plants
(Wiley, Hoboken, 2020)
This paper presents alternatives to Kalina cycles typically used in place of the organic Rankine cycle in biomass power plants. Overviews of both Rankine and Kalina cycles are given alongside the possibilities of using ...
Mathematical modelling and optimisation of lignite and wheat straw co-combustion in 350 MWe boiler furnace
(Elsevier Sci Ltd, Oxford, 2020)
In this paper pulverised lignite-fired 350 MWe boiler furnace is selected for numerical simulations performed by using in-house developed computer code to deepen understanding of complex processes during direct co-firing ...
Integration of solar energy by nature-inspired optimization in the context of circular economy
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The purpose of this paper is to make a research on solar power plants integration in an electric power system, taking into account all costs arising from circular economy criteria. Four scenarios of solar power plant ...
The error bounds of Gauss quadrature formulae for the modified weight functions of Chebyshev type
(Elsevier Science Inc, New York, 2020)
In this paper, we consider the Gauss quadrature formulae corresponding to some modifications of each of the four Chebyshev weights, considered by Gautschi and Li in [4]. As it is well known, in the case of analytic integrands ...
PVDF-HFP/NKBT composite dielectrics: Perovskite particles induce the appearance of an additional dielectric relaxation process in ferroelectric polymer matrix
(Elsevier Sci Ltd, Oxford, 2021)
Na0.25K0.25Bi0.5TiO3 (NKBT) perovskite particles are synthesized by solid-state method and used as a filler for polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) co-polymer. X-ray diffraction analysis of NKBT powders ...
Thermomechanical behavior of bio-fiber composite thermal insulation panels
(Elsevier Science Sa, Lausanne, 2020)
The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
