Fixed point results of F-rational cyclic contractive mappings on 0-complete partial metric spaces
( Forum-Editrice Universitaria Udinese SRL , 2018 , Article)Wardowski [19] introduced a new concept of contraction which called F-contraction and proved a fixed point theorem on complete metric space. Following this direction of research, in this paper, we introduce an F-rational ... -
Fixed point results using Ft-contractions in ordered metric spaces having t-property
( MDPI AG , 2019 , Article)In this paper, we prove the existence of fixed points of Ft-contraction mappings in partially ordered metric spaces not necessarily complete. We require that the ordered metric space has the t-property, which is a new ... -
Fixed point theorems for weakly T-Chatterjea and weakly T-Kannan contractions in b-metric spaces
( Springer-Verlag , 2014 , Article)In this work, we obtain some fixed point results for generalized weakly T-Chatterjea-contractive and generalized weakly T-Kannan-contractive mappings in the framework of complete b-metric spaces. Examples are provided in ... -
Flow and heat transfer analysis of Jeffery nano fluid impinging obliquely over a stretched plate
( Taiwan Institute of Chemical Engineers , 2017 , Article)This study investigates the problem of oblique stagnation point flow using Jeffery nanofluid as a rheological fluid model. Effects of thermophoresis and Brownian motion are taken into account. The governing nonlinear partial ... -
Forecasting the impact of environmental stresses on the frequent waves of COVID19
( Springer , 2021 , Article)A novel approach to link the environmental stresses with the COVID-19 cases is adopted during this research. The time-dependent data are extracted from the online repositories that are freely available for knowledge and ... -
Formation of a cold antihydrogen beam in AEGIS for gravity measurements
( AIP Publishing , 2008 , Article)The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the ... -
Frequency conversion layers for Si solar cell efficiency improvement
( Springer Nature , 2017 , Book chapter)SiNx and SiNx: Tb3+ thin layers deposited by reactive magnetron co-sputtering have been studied with the aim of optimizing the light management in Si solar cells. Those Si-based layers are developed to be compatible with ... -
Functional linear models for interval-valued data
( Taylor and Francis Group , 2022 , Article)Aggregation of large databases in a specific format is a frequently used process to make the data easily manageable. Interval-valued data is one of the data types that is generated by such an aggregation process. Using ... -
Fuzzy linear programming for supply chain management in steel industry
( Hikari Ltd. , 2014 , Article)Linear programming is one of the frequently applied tools in supply chain management. However, managers and decision makers may lack information about exact values of most of the parameters used in the optimization models. ... -
Gamma irradiation effects on polymethyl methacrylate
( WILEY-VCH Verlag , 2007 , Article)The effect of gamma-irradiation on the structure of polymethyl methacrylate (PMMA) has been investigated. In this study, the PMMA specimens were gamma-irradiated at doses in the range of 0-1000 kGy and measured by means ... -
Gender Difference in Teachers' Mathematical Knowledge for Teaching in the Context of Single-Sex Classrooms
( Springer Netherlands , 2016 , Article)This study examines gender differences of teachers on their mathematical knowledge for teaching in the context of single-sex classrooms in Saudi Arabia. A translated version of the Mathematical Knowledge for Teaching (MKT) ... -
The general solution for the relativistic and nonrelativistic Schrödinger equation for the δ(n) -function potential in 1-dimension using cutoff regularization, and the fate of universality
( World Scientific Publishing , 2022 , Article)A general method has been developed to solve the Schrödinger equation for an arbitrary derivative of the δ-function potential in 1-d using cutoff regularization. The work treats both the relativistic and nonrelativistic ... -
