Luminescent Eu3+-doped transparent alumina ceramics with high hardness
(Elsevier, 2017-05-17)The Eu3+-doped transparent aluminas were prepared by wet shaping technique followed by pressureless sintering and hot isostatic pressing. The effect of dopant amount on microstructure, real in-line transmission (RIT), ... -
Local controllability of trident snake robot based on sub-Riemannian extremals
(Universit`a del Salento, 2017-05-24)To solve trident snake robot local controllability by differential geometry tools, we construct a privileged system of coordinates with respect to the distribution given by Pffaf system based on local nonholonomic conditions ... -
High repetition rate laser-induced breakdown spectroscopy using acousto-optically gated detection
(AIP Publishing, 2014-07-24)This contribution introduces a new type of setup for fast sample analysis using laser-induced breakdown spectroscopy (LIBS). The novel design combines a high repetition rate laser (up to 50 kHz) as excitation source and ... -
A ternary relation for structuring the digital plane
(EDP Sciences, 2017-01-12)We discuss certain ternary relations, called plain, and show that each of them induces a connectedness on its underlying set. This connectedness allows for definitions of concepts of simple closed and Jordan curves. We ... -
On a product of universal hyperalgebras
(Faculty of Mathematics and Computer Science, Ovidius University, 2015-05-15)We introduce and study a new operation of product of universal hyperalgebras which lies, with respect to set inclusion, between the cartesian product of the hyperalgebras and the cartesian product of their idempotent hulls. ... -
On the stability of some properties of partial algebras under powers
(SAV, 2014-04-01)In the paper, we study eight properties of partial algebras most of which are related to diagonality. For each of the properties, we give sufficient conditions under which this property is preserved by powers of partial algebras. -
Multivariate classification of echellograms: a new perspective in Laser-Induced Breakdown Spectroscopy analysis
(Springer Nature, 2017-12-01)In this work, we proposed a new data acquisition approach that significantly improves the repetition rates of Laser-Induced Breakdown Spectroscopy (LIBS) experiments, where high-end echelle spectrometers and intensified ... -
Topological structuring of the digital plane
(DMTCS, 2013-08-01)We discuss an Alexandroff topology on the digital plane having the property that its quotient topologies include the Khalimsky and Marcus-Wyse topologies. We introduce a further quotient topology of the topology discussed and ... -
Fracture mechanics parameters of multilayer pipes
(University of West Bohemia, 2007-10-19)Multilayer pipes consisting of different materials are frequently used in praxis because of partial improvement of the properties of pipe systems. To estimate lifetime of these pipes the basic fracture parameters have to ... -
Case study: the influence of oil-based friction modifier quantity on tram braking distance and noise
(Serbian Tribology Society, 2017-06-21)In the present study, the twin disc machine and the light rail system was employed in order to investigate the ability of oil-based friction modifier (FM) to optimize adhesion and to reduce noise. The risks associated with ... -
Crack propagation in the vicinity of the interface in layered materials
(University of West Bohemia, 2009-01-04)Paper deals with the problem of crack propagation in the vicinity of the interface in layered materials. Layered materials are often used in practice, primarily because of their better mechanical properties in comparison ... -
Tribological studies on copper-based friction linings
(Faculty of Engineering, University of Kragujevac, Serbia, 2017-06-22)The objects of this work were nine different copper-based friction linings produced from powder by pressing and sintering. Six copper-based friction linings contained 3 wt.% zinc (Zn) and variable content of tin (Sn), i.e. ... -
Applications of the discontinuous Galerkin method to propagating acoustic wave problems
(SAGE Publishing, 2017-06-16)The purpose of this article is to demonstrate that the discontinuous Galerkin method is efficient and suitable to solve linearized Euler equations, modelling sound propagation phenomena. -
Selection of MEMS Accelerometers for Tilt Measurements
(Hindawi, 2017-03-30)In order to build a tilt sensor having a desired sensitivity and measuring range, one should select an appropriate type, orientation, and initial position of an accelerometer. Practical guidelines for an optimal selection ... -
Modelling of consequences of biogas leakage from gasholder
(University of Zagreb - Faculty of Agriculture, 2017-01-01)This paper describes modelling of consequences of biogas leakage from a gasholder on agricultural biogas station. Four scenarios were selected for the purpose of this work. A rupture of gasholders membrane and instantaneous ... -
Experimental comparison of the behavior between base oil and grease starvation based on inlet film thickness
(Serbian Tribology Society, 2017-03-24)This paper deals with the experimental study of an elastohydrodynamic contact under conditions of insufficient lubricant supply. Starvation level of this type of the contact may be experimentally determined based on the ... -
X-ray induced electrostatic graphene doping via defect charging in gate dielectric
(NPG, 2017-04-03)Graphene field effect transistors are becoming an integral part of advanced devices. Hence, the advanced strategies for both characterization and tuning of graphene properties are required. Here we show that the X-ray ... -
Lubricant flow in thin-film elastohydrodynamic contact under extreme conditions
(Tsinghua University Press, 2016-12-01)To further extend knowledge about fluid film friction in elastohydrodynamic contact, it is important to examine how lubricant flows. In this paper, several film thickness results obtained by interferometry technique for ... -
Mixed Lubrication Solution of Dynamically Loaded Radial Slide Bearings
(Faculty of Engineering, University of Kragujevac, 2017-03-23)A solution of radial slide bearing dynamics and tribology incorporating the influences of real surface roughness contacts or the influence of surface roughness on bearing lubrication is presented in this paper. Finite ... -
Use of micro computed-tomography and 3D printing for reverse engineering of mouse embryo nasal capsule
(IOP Publishing, 2016-03-02)Imaging of increasingly complex cartilage in vertebrate embryos is one of the key tasks of developmental biology. This is especially important to study shape-organizing processes during initial skeletal formation and growth. ...
