Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier Sci Ltd, Oxford, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100-240 min) and ...
Multistep generalized transformation method applied to solving equations of discrete and continuous time-fractional enzyme kinetics
(Elsevier Science Bv, Amsterdam, 2017)
In this paper, Caputo based Michaelis-Menten kinetic model based on Time Scale Calculus (TSC) is proposed. The main reason for its consideration is a study of tumor cells population growth dynamics. In the particular case ...
Closed-form solution for the free axial-bending vibration problem of structures composed of rigid bodies and elastic beam segments
(Elsevier Science Inc, New York, 2020)
In this paper, the coupled axial-bending vibration of planar serial frame structures composed of rigid bodies and Euler-Bernoulli beam segments is considered. The corresponding mode orthogonality conditions for this kind ...
Nonlinear vibration of a nonlocal functionally graded beam on fractional visco-Pasternak foundation
(Springer, Dordrecht, 2022)
This paper investigates the nonlinear dynamic behavior of a nonlocal functionally graded Euler-Bernoulli beam resting on a fractional visco-Pasternak foundation and subjected to harmonic loads. The proposed model captures ...
On the problem of a heavy homogeneous ball rolling without slipping over a fixed surface of revolution
(Elsevier Science Inc, New York, 2022)
The paper considers a heavy homogeneous ball rolling without slipping on the outside of a real rough fixed surface of revolution, which is generated by rotating a plane curve around a vertical axis. By applying the Coulomb ...
Humidity sensing properties of nanocrystalline pseudobrookite (Fe2TiO5) based thick films
(Elsevier Science Sa, Lausanne, 2018)
Pseudobrookite based nanopowder was obtained by solid state synthesis of starting hematite and anatase nanopowders in the weight ratio 55:45. Structural and morphological properties were analyzed using X-ray diffraction ...
Numerical study of pulverized coal-fired utility boiler over a wide range of operating conditions for in-furnace SO2/NOx reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Important tasks during pulverized coal-fired utility boiler exploitation are efficient utilization of variable quality fuels, operation in a wide range of loads and emission reduction of pollutants, like oxides of nitrogen ...
Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
