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 ...
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 ...
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 ...
Speaker Recognition Using Constrained Convolutional Neural Networks in Emotional Speech
(Molecular Diversity Preservation International, 2022-03-16)
Speaker recognition is an important classification task, which can be solved using several
approaches. Although building a speaker recognition model on a closed set of speakers under neutral speaking conditions is a ...
Design of a 2-Bit Neural Network Quantizer for Laplacian Source
(Molecular Diversity Preservation International, 2021-07-22)
Achieving real-time inference is one of the major issues in contemporary neural network applications, as complex algorithms are frequently being deployed to mobile devices that have constrained storage and computing power. ...
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 ...
Theoretical investigation of bandwidth of multimode step-index silica photonic crystal fibers
(MDPI, 2022-03-23)
Solving the time-dependent power flow equation (PFE) provides a useful method to study
the transmission bandwidth of step-index silica photonic crystal fibers (SI SPCFs). The transmission
bandwidth of these kinds of ...
Theoretical investigation of the capacity of space division multiplexing with step-index air-clad silica optical fibers
(MDPI, 2022-02-23)
We studied the effect of mode coupling on the space division multiplexing (SDM) capabilities of multimode step-index (SI) air-clad silica optical fibers by numerically solving the power
flow equation. Mode coupling ...
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 ...
