Statistical methods for designing a Geiger-Muller counter suitable for an early warning system
(Elsevier, 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier, 2019)
Highly ordered, anodically grown TiO2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping (≤2 at.%) in the titanium oxide lattice. FESEM micrographs revealed nanotubes ...
The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...
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 ...
Investigation into the causes of fracture in railway freight car axle
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Railway axles are vital parts of railway. Their failure in the form of dynamic fracture is commonly of disastrous outcomes for railway vehicles. Accordingly, railway axles are designed to be highly reliable, while the ...
Free vibration of structures composed of rigid bodies and elastic beam segments
(Academic Press Ltd- Elsevier Science Ltd, London, 2015)
Free vibration of structures composed of rigid bodies and elastic beam segments is considered, assuming that the mass centers of rigid bodies are not located on the neutral axes of undeformed elastic beam segments. It is ...
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 ...
Mass minimization of an Euler-Bernoulli beam with coupled bending and axial vibrations at prescribed fundamental frequency
(Elsevier Sci Ltd, Oxford, 2021)
The problem of determining the optimum shape of a homogeneous Euler-Bernoulli beam of a circular cross-section, in which the coupled axial and bending vibrations arose due to complex boundary conditions, is considered. The ...
First passage of stochastic fractional derivative systems with power-form restoring force
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this paper, the first-passage failure of stochastic dynamical systems with fractional derivative and power-form restoring force subjected to Gaussian white-noise excitation is investigated. With application of the ...
