In this study, we have introduced the bipolar fuzzy soft (D-)metric
space which is based on bipolar fuzzy soft point of bipolar fuzzy soft sets and
give some of their properties. Also, the bipolar ...fuzzy soft sequences and bipolar
fuzzy soft cauchy sequences concepts have been studied with the help of defined
metric spaces and some of their properties have been investigated. In addition
to all this, many examples are given in order to better understand the concepts
and features studied and contribute to a better understanding of the paper.
This paper consist of three main sections. In the first part, we
obtain the complete lifts of the Fa(5, 1)-structure on tangent bundle. We have
also obtained the integrability conditions by ...calculating the Nijenhuis tensors
of the complete lifts of Fa(5, 1)-structure. Later we get the conditions of to be
the almost holomorfic vector field with respect to the complete lifts of Fa(5, 1)-structure. Finally, we obtained the results of the Tachibana operator applied
to the vector fields with respect to the complete lifts of Fa(5, 1)-structure on
tangent bundle.
In this paper, the Klein - Gordon equation is generalized using the
concept of the variational order derivative. We try to construct the Crank-
Nicholson scheme for numerical solutions of the ...modified Klein- Gordon equa-
tion. Stability analysis of the Crank-Nicholson scheme is examined and ana-
lyzed to prove the proposed method is stable for solving the time-fractional
variable order Klein- Gordon equation. Numerical examples are also given for
illustration.
In this paper, using the Calkin-Gorbachuk method, the general
form of all maximal dissipative extensions of the minimal operator generated by
rst order linear multipoint symmetric singular ...di¤erential-operator expression
in the direct sum of Hilbert space of vector-functions has been found. Later
on, the structure of spectrum of these extensions is researched. Finally, the
results are supported by an application.
This article presents di¤erent parameter estimation methods for
exible Weibull distribution introduced by Bebbington et al. (Reliability En-
gineering and System Safety 92:719-726, 2007), which is a ...modi ed version
of the Weibull distribution and is suitable to model di¤erent shapes of the
hazard rate. We consider both frequentist and Bayesian estimation methods
and present a comprehensive comparison of them. For frequentist estima-
tion, we consider the maximum likelihood estimators, least squares estima-
tors, weighted least squares estimators, percentile estimators, the maximum
product spacing estimators, the minimum spacing absolute distance estima-
tors, the minimum spacing absolute log-distance estimators, Cramér von Mises
estimators, Anderson Darling estimators, and right tailed Anderson Darling
estimators, and compare them using a comprehensive simulation study. We
also consider Bayesian estimation by assuming gamma priors for both shape
and scale parameters. We use a Markov Chain Monte Carlo algorithm to
compute the posterior summaries. A real data example is also a part of this
work.

In this paper, we rstly give an alternative method to determine
the size of C(Sn) which is the set of elements of type Sn in a nite Cox-
eter system (Wn; Sn) of type Bn.
In this article, light-like hypersurfaces which are derived by null
Cartan curves are examined and discussed. The singularities of lightlike hy-
persurfaces and light-like focal sets are investigated ...by using the Bishop frame
on the Null Cartan curves. We obtain that the types of these singularities
and the order of contact between the null Cartan curves are closely related
to the Bishop curvatures of the null Cartan curves. Moreover, two examples
of light-like hypersurfaces and light-like focal sets are given to illustrate our
theoretical results.
