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 ...
(C , Ψ * , G ) Class of Contractions and Fixed Points in a Metric Space Endowed with a Graph
(MDPI (Basel, Switzerland), 2019-05-27)
In this paper, we introduce the (C,Ψ∗,G) class of contraction mappings using C-class functions and some improved control functions for a pair of set valued mappings as well as a pair of single-valued mappings, and prove ...
Existence and Unique Coupled Solution in Sb-Metric Spaces by Rational Contraction with Application
(MDPI (Basel, Switzerland), 2019-03-28)
In this paper, we prove a unique common coupled fixed point theorem for two pairs of w-compatible mappings in Sb -metric spaces. We also furnish an example to support our main result.
Application of Mellin Transforms in Determination the Probability Distribution of the Stochastic Volatility Models
In this paper, an application of the Stochastic Mellin Transforms (SMTs) in determination of the probability distribution functions (PDFs) of the Stochastic Volatility (SV) models is proposed. In that aim, three basic SV ...
Some Remarks and New Results in Ordered Partial b-Metric Spaces
(MDPI (Basel, Switzerland), 2019-04-06)
We improve and generalize some new results in fixed point theory in the context of partial b-metric spaces
The influence of different doses of γ-radiation on the hydrolytic stability of modified urea-formaldehyde (UF) resins
Zbog emisije formaldehida (СН2О) iz drvenih proizvoda, gde se urea- formaldehidne (UF) smole, izmedu ostalog, koriste za impregnaciju drvenih panela koje se koriste u unutrasnjosti stambenih i drugih objekata ...
First study of electrochemical behavior of herbicide pethoxamid and its voltammetric determination in river water
Pethoxamid (РОА) is relatively new herbicide and it belongs to group of chloroacetamides. lt inhibits the germination of target weeds in com, soybeans, peas and beans, tobacco and other crops and it can affects on ...
Morfološka i elektrohemijska karakterizacija nanočestica srebra i gvožđe-oksida namenjenih za elektroanalizu
Nanočestice metala i oksida metala (NPs) privlače pažnju mnogih istraživača zbog svojih jedinstvenih optičkih i električnih svojstva. Ove nanočestice nalaze primenu u biologiji, medicini, kao i u elektronici, za izradu ...
Nano-Fe2O3 particles as voltammetric signal amplifiers in sensing of heavy metals and pesticides
Nanočestice na bazi oksida gvožđa (NPs) su privukle veliku pažnju imajući u vidu njihove fizičke, posebno magnetne, i hemijske osobine. U ovom istraživanju su nanočestice gvožđe(III)-oksida (Fe2O3 NPs) sintetisane jednostavnim ...
