I-lacunary statistical convergence of sequences of sets
(Faculty of Sciences and Mathematics, University of Nis, 2014)In this paper we study the concepts of Wijsman I-statistical convergence, Wijsman I-lacunary statistical convergence and Wijsman strongly I-lacunary convergence of sequences of sets and investigate the relationship between them -
Lacunary statistical summability of sequences of sets
(Konuralp Journal of Mathematics, 2015)In this paper we define the WS_θ-analog of the Cauchy criterion for convergence and show that it is equivalent to Wijsman lacunary statistical convergence. Also, Wijsman lacunary statistical convergence is compared to other ... -
An extension of asymptotically lacunary statistical equivalence set sequences
(Springer, 2014)This paper presents, for sequences of sets ,the notions of asymptotically lacunary statistical equivalence (in the sense of Wijsman) of multiplicity L, strongly asymptotically lacunary p-equivalence (in the sense of Wijsman) ... -
On almost asymptotically lacunary statistical equivalence of sequences of sets
(Fractional Calculus and Application Group, 2014)In this paper we study the concepts of Wijsman almost asymptotically statistical equivalent, Wijsman almost asymptotically lacunary statistical equivalent and Wijsman strongly almost asymptotically lacunary equivalent sequences ... -
On strongly lacunary summability of sequences of sets
(Journal of Applied Mathematics & Bioinformatics, 2013)In this paper, we introduce the concept of Wijsman strongly lacunary summability for set sequences. Then, we discus its relation with Wijsman strongly Ces`aro summability. Furthermore, we also give its relation with Wijsman ... -
On asymptotically lacunary statistical equivalent set sequences
(Hindawi Publishing Corporation, 2013)This paper presents three definitions which are natural combination of the definitions of asymptotic equivalence, statistical convergence, lacunary statistical convergence, and Wijsman convergence. In addition, we also ... -
Electrochemical corrosion behavior of high velocity Oxy-Fuel (HVOF) superalloy coatings on ductile irons
(Sakarya University Journal of Science, 2019)In this study, alloyed and unalloyed ductile irons (DI) were coated with two different Ni-based superalloy materials by HVOF method. Microstructure and phase analyzes of the coatings were performed by using SEM, EDX, XRD ... -
Effects of CO2 and H2S on corrosion of martensitic steels in brines at low temperature
(Nace International, 2018)Corrosion studies were conducted for martensitic carbon steels in 5 wt% NaCl brine solutions at 4°C and 10 MPa (1,450 psi). These studies simulated different subsurface environments relevant to Arctic drilling. Here, two ... -
Investigation of corrosion and wear behavior of borided AISI P20 steel in micro-wave furnace
(IOP Publishing, 2019)In this study, the effect of microwave boronizing treatment on the corrosion and wear behaviour of boride layer formed on AISI P20 steel have been investigated. The boronizing treatment was carried out using Ekabor-II ... -
Electrochemical corrosion of Ti6Al4V, Ti and AISI 316L SS after immersed in concentrated simulated body fluid

Lacunary statistical convergence of sequences of sets
(Canadian Research & Development Center of Sciences and Cultures, 2012)Several notions of convergence for subsets of metric space appear in the literature. In this paper we define lacunary statistical convergence for sequences of sets and study in detail the relationship between other convergence ... -
