Comparison of adaptive algorithms for free space optical transmission in Malaga atmospheric turbulence channel with pointing errors
(2019)
In this study, the authors investigate average capacity of free space optics communication over Málaga atmospheric turbulence channel with pointing errors and path loss, for intensity modulated/direct detection (IM/DD) and ...
Dislocated quasi cone b-metric space over Banach algebra and contraction principles with application to functional equations
(De Gruyter Open Access, 2019-08-09)
In this paper we introduce dislocated and dislocated quasi version of a cone b-metric space over a Banach algebra as well as weak semi α-admissible and α-identical pair of mappings and prove common fixed point theorems for ...
Caristi, Nadler and H + -Type Contractive Mappings and Their Fixed Points in θ-Metric Spaces
(MDPI (Basel, Switzerland), 2019-04-07)
A new proper generalization of metric called as θ -metric is introduced by Khojasteh et al. (Mathematical Problems in Engineering (2013) Article ID 504609). In this paper, first we prove the Caristi type fixed point theorem ...
Total Normalcy of Knots
(Faculty of Sciences and Mathematics, University of Niš, 2019-01-01)
In this paper we consider first order infinitesimal bending of curves and knots. The total
normalcy of the knot during the first order infinitesimal bending is discussed and expressions for the first variation of the total ...
A new longipinane ketone from Achillea abrotanoides (Vis.) Vis.: chemical transformation of the essential oil enables the identification of a minor constituent
(Wiley-VHCA AG, Zurich, Switzerland, 2019-12-10)
Introduction: Minor plant constituents are difficult to identify due to the challenging
isolation and acquiring of reliable spectral data. Essential oils abound in such minor
constituents that might be of high importance ...
Optimization and validation of the kinetic spectrophotometric method for quantitative determination of the pesticide atrazine and its application in infant formulae and cereal-based baby food
(Wiley-VHCA AG, Zurich, Switzerland, 2019-05-11)
BACKGROUND: Pesticides are potentially toxic to humans and can produce both acute and chronic health effects, depending on the quantity and the ways in which a person is exposed. Exposure to pesticides can cause serious ...
