On Relations for the Moment Generating Functions from the Extended Type II Generalized Logistic Distribution Based on K-TH Upper Record Values and A Characterization
In this study we, give some new explicit expressions and recurrence relations satisfied by marginal and joint moment generating functions of k-th upper record values from extended type II generalized logistic distribution. Next we show that results for upper record values of this distribution can be derived from our result as special cases. Further, a characterizing result of this distribution on using the conditional expectation of upper record values is discussed. |

Radio Mean Number of Some Wheel Related Graphs
A Radio Mean labeling of a connected graph G is an injective map f from the vertex set V (G) to the set of natural numbers N such that for each distinct vertices u and v of G, d (u, v) + [(f(u)+f(v))/2]≥1+diam(G). The radio mean number of f, rmn(f), is the maximum number assigned to any vertex of G under the labeling f. The radio mean number of G, rmn(G) is the minimum value of rmn(f) taken over all radio mean labelings f of G. Here we have found the radio mean number of some graphs derived from wheels. |

Application
to
IFS’S:
the
Non-Convex
Case
In this
paper we
prove
that
systems
generated
by
uniformly

contractive
set-valued
mappings
are
bi-shadowing
with
respect
to
comparison
set
valued
contractive
mappings
that
have
nonempty
and
compact
(not
necessarily

values.
An

On Some
Covering
Properties
in Terms
of Fuzzy
Grill
In this
paper
our
primary
intension
is to
develop
some
fuzzy
grill
oriented
compact-like
notions
through
α-shading
in a
fuzzy
topological
space.
Moreover,
we
characterize
these
ideas by
means of
α-finite
union
property,
prefilterbases,
prefilters
and
fuzzy
grills
via some
pre-assigned
fuzzy
grill
and the
underlying
fuzzy
topology.

by
utilizing
βθ-open
