In the rst part of this work we present several new geometric
properties of analytic functions by applying the di¤erential subordination. In
addition, several results in the geometric functions ...theory pointed out.
In the present paper, a new type of special curve couple which are
called WC"-partner curves are introduced according to alternative moving
frame {N,C,W}. The distance function between the ...corresponding points of
reference curve and its partner curve is obtained. Besides, the angle function
between the vector elds of alternative frame of the curves is expressed by
means of alternative curvatures f and g. In addition to these, various charac-
terizations are obtained related to these curves.

In previous papers, several To-objects in set-based topological cat-
egory have been introduced and compared. In this paper, we give the char-
acterization of general To (resp. To, and T'o) ...convergence approach spaces as
well as show how these notions are linked to each other.
In the present paper our aim is to investigate lightlike hyper-
surfaces of R41
having degenerate or non-degenerate planar normal sections.
Firstly, we prove that lightlike hypersurfaces in R41
...always have degenerate
planar normal sections. Then we examine the conditions for lightlike hyper-
surfaces in R41
to have non-degenerate planar normal sections and obtain some
characterizations for such lightlike hypersurfaces.

The aim of the present paper is to define Ka-continuity which is
associated to the number sequence a = (an) and to give some new results.
In this paper, we characterize various local T2 extended pseudo-
quasi-semi metric spaces and investigate the relationships among these various
forms. Finally, we give some invariance properties of ...these local T2 extended
pseudo-quasi-semi metric spaces.
In this paper, we introduce a new class of extended (a;m1;m2)-convex functions. Some algebraic properties of these class functions have been investigated. Some new Hermite-Hadamard type inequalities ...are derived. Results represent signicant refinement and improvement of the previous results. Also, the author establish a new integral identity and, by this identity, Hölder's and power mean inequality, discover some new Hermite-Hadamard type inequalities for functions whose first derivatives are (a;m1;m2)-convex. Our results are new and coincide with the previous results in special cases.
A Shewhart chart based on normality assumption is not appropriate for skewed distributions since its Type-I error rate is inflated. This study presents X and S control charts for monitoring the ...process variability for skewed distributions. We propose Weighted Standard Deviation (WSD) X and S control charts. Standard deviation estimator is applied to monitor the process variability for estimating the process standard deviation, in the case of the WSD X and S control charts as this estimator is simple and easy to compute. Unlike the Shewhart control chart, the proposed charts provide asymmetric limits in accordance with the direction and degree of skewness to construct the upper and lower limits. The performances of the proposed charts are compared with other heuristic charts for skewed distributions by using Simulation study. The Simulation studies show that the proposed control charts have good properties for skewed distributions and large sample sizes.
