The assessment of aridity in Leskovac Basin, Serbia (1981-2010)
(2018-08-25)
In the paper, the aridity is defined on the basis of four climate indices: De Martonne's index of aridity, Lang’s Rain Factor and Gračanin’s Rain factor for the vegetation period and hydrothermal coefficient of Seljaninov. ...
A stochastic model for estimation of repair rate for system operating under performance based logistics
(Polish Maintanace Society, 2018-09-01)
Performance Based Logistics (PBL) concept has an aim to improve the system availability and it has been extensively researched in the recent years. These researches showed that inventory level does not impact system ...
C-class functions on some fixed point results in ordered partial metric spaces via admissible mappings
(Department of Mathematics and Informatics, Faculty of Sciences, Novi Sad, 2018-06-05)
In this paper, we generalized the results presented in the paper W. Long, S. Khaleghizadeh, P. Salimi, S. Radenović and S. Shukla, Some new fixed point results in partially ordered metric spaces via admissible mappings, ...
Some remarks on TAC-contractive mappings in b-metric spaces
(Društvo matematičara Srbije, 2018-09-03)
In this paper we complement and improve fixed point results established on
TAC-contractive mappings in the framework of b-metric spaces. Our analysis starts by a
recent paper of Babu and Dula [G. V. R. Babu and T. M. ...
Synthesis and spectral characterization of asymmetric azines containing a coumarin moiety: The discovery of new antimicrobial and antioxidant agents
(2018-10-25)
Nine unsymmetrical azines containing a coumarin moiety were prepared by the reaction of the hydrazone of 4-hydroxy-3-acetylcoumarin with differently substituted aromatic aldehydes. The azines were fully spectrally ...
SSC Reception over Kappa-Mu Shadowed Fading Channels in the Presence of Multiple Rayleigh Interferers
(Kaunas University of Technology, 2018-06-22)
Modelling of complex wireless transmission scenario over fading channels in the presence of multiple co- channel (CCI) interferers will be presented in this paper. Propagation environment will be modelled with general ...
Influence of zero boresight and non-zero boresight pointing error on BER FSO transmission over Malaga atmospheric channel
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2018-03-22)
In this paper, the influence of a zero and a non-zero boresight pointing errors on the performances of free-space optic transmission over the Málaga atmospheric turbulence channel is considered. Closed form expressions for ...
Interaction between gold nanoparticles and selected antitumor gold complexes
(Society of Physical Chemists of Serbia, 2018-09-28)
The paper presents the results of study of interaction between citrate capped gold nanoparticles (AuNPs) and some antitumor gold complexes with pyridine ligands (AubipyC, AubipyOH and AupyOAc), in order to elucidate the ...
DOPRINOS FIGURATIVNIH BROJEVA RAZVOJU VIZUELNO LOGIČKOG PRISTUPA REŠAVANJU ZADATAKA SA BROJNIM NIZOVIMA
(Univerzitetska misao - časopis za nauku, kulturu i umjetnost, Novi Pazar, 2018-05-01)
Savremena nastava matematike na svim nivoima obrazovanja uglavnom se svodi na primenu algebarskih formula i algebarskih postupaka. Vizuelno-logički pristup sagledavanju i rešavanju matematičkih zadataka vrlo malo je prisutan ...
Hybrid modification of accelerated double direction method
(Hindawi, 2018-11-06)
We present a hybridization of the accelerated gradient method with two vector directions. This hybridization is based on the usage of a chosen three-term hybrid model. Derived hybrid accelerated double direction model keeps ...
