We establish a common fixed point theorem for weakly compatible mappings generalizing a result of Khan and Kubiaczyk 1988. Also, an example is given to support our generalization. We also prove common fixed point theorems for weakly compatible mappings in metric and compact metric spaces.
The problem of the parameterization of data points in NURBS curve/surface has been considered by amount of researchers. In this study, a new parameterization method considered as hybrid parameterization method is proposed. Like universal method, this method uses the property of ¿at each span index, there is exactly one maximum value of the rational B-spline… (More)
The distribution of hadrons produced in deeply inelastic electron–proton collisions depends on the azimuthal angle between lepton scattering plane and hadron production plane in the photon-proton centre-of-mass frame. In addition to the well known up-down asymmetry induced by the azimuthal dependence of the Born level subprocess, there is also a… (More)
In the present paper, we prove some fixed point theorems of Hegedus contraction in some types of distance spaces, dislocated metric space, left dislocated metric space, right dislocated metric space and dislocated quasi-metric metric space which are generalized metrics spaces where self-distances are not necessarily zero.
Accident forecasting is designed to help decision making and planning before loss occur; a new method of combination forecasting applied in traffic accident is showed in this paper. It is based on the rough sets theory, and the weighting coefficient of all the forecast models, so the result of forecasting will be more precise. Based on the mean relative… (More)
It is extremely inevitable for classroom interaction to involve students to work in groups. The study aims at utilizing cooperative learning strategy to maximize classroom interaction in secondary school level at Damazeen city. The study follows the descriptive analytical method and uses a questionnaire as a tool for data collection. In practice two… (More)
Laminar natural convection in differentially heated (β = 0°, where β is the inclination angle), inclined (β = 30° and 60°), and bottom-heated (β = 90°) square enclosures filled with a nanofluid is investigated, using a two-phase lattice Boltzmann simulation approach. The effects of the inclination angle on Nu number and convection heat transfer coefficient… (More)
In this paper, the problem of reducing control points for surface reconstruction is addressed. A new parameterization method considered as hybrid method for NURBS surface is presented. This method allows multiple knots, and very close domain knots. The proposed method and another three conventional methods (uniform, cord length and centripetal) are applied… (More)
