Numerical Solution of Bioheat Transfer Model using Generalized Wavelet Collocation Method
In this article, we develop a a generalized wavelet collocation method based on a Haar wavelet to facilitate the solution of modified Pennes bio-heat transfer model during thermal therapy. The process of heat transfer in living biological tissue is studied under various coordinate systems. Contrary to the existing operational matrix methods based on orthogonal functions, we construct the Haar wavelet operational matrices of integration without using the block pulse functions. The temperature distribution inside a living biological tissue has been investigated for different estimations of thermal conductivity, antenna power constant, and surface temperature. The numerical results obtained shows that the desired temperature occur faster in spherical symmetric coordinate as compared to axisymmetric coordinate where as temperature in axisymmetric coordinate occur faster in comparison
to cartesian coordinate. The performance and accuracy of the proposed technique is elucidates by a comparison of the numerical outcomes with homotopy perturbation method and the exact solution of the model.

Frame Systems in Non-Locally Convex Banach Spaces
In this paper, we define atomic decompositions in a non- locally convex Banach space Ɩp (0 < p ≤ 1) and discuss its existence through examples. Also, a sufficient condition for its existence is given and it is observed that if a p-Banach space has an atomic decomposition, then the space is isomorphic to its associated p-Banach sequence space. Further, necessary and sufficient conditions for an atomic decomposition in a p-Banach space is given. Finally, we define shrinking atomic decomposition and gave a necessary and sufficient condition for it.

On Star Coloring of Degree Splitting of Cartesian Product Graphs
A star coloring of a graph G is a proper vertex coloring with the condition that no path on four vertices in G can be labelled by two colors. The star chromatic number χs (G) of G is the least number of colors that is required to star color G. In this paper, we determine the star chromatic number of the degree splitting graph of the Cartesian product of any two simple graphs G and H denoted by G□H and also we portray the star chromatic number for the degree splitting graph of the Cartesian product of prism graphs, toroidal graphs and grid graphs.

Construction
of a Riesz
Wavelet
Basis on
Locally
Compact
Abelian
Groups
We have
explored the
concept of
Riesz
multiresolution
analysis on
a locally
compact
Abelian
group G, and
have
extensively
studied the
methods of
construction
of a Riesz
wavelet from
the given
Riesz MRA.
We have
proved that,
if δα is the
order of
dilation,
then
precisely δα−1
functions
are required
to construct
a Riesz
wavelet
basis for L2
(G). An
example,
supporting
our theory
and
illustrating
the methods
developed,
has also
been
discussed in
detail. |

Topology
In this
paper, the
notions of

obtained. In
this

On α − and α
*−
T0
and T1
Separation
Axioms In
I− Fuzzy
Topological
Spaces
Sostak and
Kubiak
introduced
I−fuzzy
topological
spaces.
Subspaces
and products
of I−fuzzy
topological
spaces have
been
introduced
and studied
by Peeters
and Sostak.
Srivastava
et al.
introduced
and studied
α− and α*−Hausdorff
I−fuzzy
topological
space.
George and
Veeramani
improved the
definition
of a fuzzy
metric,
which was
first
introduced
by Kramosil
and Michalek.
Grecova et
al.
constructed
an LM−fuzzy
topological
space using
a strong
fuzzy
metric,
where L
and M
are complete
sublattices
of the unit
interval
[0,1]
containing 0
and 1.
This LM−fuzzy
topological
space
reduces to
an I−
fuzzy
topological
space if L =
M = I = [0,
1]. In this
paper, we
have
introduced α
− T0,
α*
− T0,
α − T1
and α*
− T1
separation
axioms in
I−fuzzy
topological
spaces and
established
several
basic
desirable
results. In
particular,
it has been
proved that
these
separation
axioms
satisfy the
hereditary,
productive
and
projective
properties.
Further, we
have proved
that in an
I−fuzzy
topological
space, α−Hausdorff⇒
α − T1
⇒ α − T0
and α*−Hausdorff⇒
α*
− T1
⇒ α*
− T0.
It has been
also shown
that an I−fuzzy
topological
space
induced by a
strong fuzzy
metric is α−Hausdorff,
for α ∈ [0,
1) and α*−Hausdorff,
for α ∈ (0,
1], which
further
implies that
this I−fuzzy
topological
space
satisfies α
− T0,
α*
− T0,
α − T1
and α*
− T1
separation
axioms. |

On Maximal
Ideal Space
of the
Functionally
Countable
Subring of
C(F)
Let X be a
Tychonoff
space and F,
a filter
base of
dense
subsets of X
(i.e., it is
closed under
finite
intersection)
and let C(F)
= limS∈F
C(S), where
C(S) is the
ring of all
real-valued
continuous
functions on
S. It is
known that
C(F) =
□{C(S) : S ∈
F }. By Cc(F)
(C*c(F)),
we mean a
subring of
C(F)
consisting
of (bounded)
functions
with
countable
range. In
this paper,
we study Mc
(M*c),
the maximal
ideal space
of Cc(F)
(C*c(F))
with the
hull-kernel
topology.
Equivalent
topology for
each of them
provided. It
is shown
that both Mc
and M*c
are T4-spaces.
More
generally,
they are
homeomorphic.
Particularly,
we prove
that the
maximal
ideal space
of Qc(X)
(qc(X))
and the
maximal
ideal space
of Q*c(X)
(q*c(X))
are
homeomorphic,
where Qc(X)
(qc(X))
is the
maximal
(classical)
ring of
quotients of
Cc(X),
and Q*c(X)
(q*c(X))
is the
subring
consisting
of bounded
functions.

Homoderivations
on a Lattice
In this
paper, the
concept of
homoderivation
on a lattice
as a
combination
of two
concepts of
meet-homomorphisms
and
derivations
is
introduced.
Some
characterizations
and
properties
of
homoderivations
are
provided.
The
relationship
between
derivations
and
homoderivations
on a lattice
is
established.
Also, an
interesting
class of
homoderivations
namely
isotone
homoderivations
is studied.
A
characterization
of the
isotone
homoderivations
in terms of
the meet-homomorphisms
is given.
Furthermore,
a sufficient
condition
for a
homoderivation
to become
isotonic is
established.

A Note on Generalized
Frame
Potential
The concept
of the frame
potential
was defined
by Benedetto
and Fickus
[1] and it
was showed
that the
finite unit
norm tight
frames can
be
characterized
as the
minimizers
of the the
energy
functional.
The concept
was
generalized
by Carrizo
and Heineken
[5] and they
introduced
the concept
of mixed
frame
potential.
In the
present
paper, we
further
generalize
the concept
introducing
the notion
of
generalized
frame
potential
and observe
that frame
potential
and mixed
frame
potential
are
particular
cases of
generalized
frame
potential.
We prove
some results
concerning
the
generalized
frame
potential. |

Evolution
Equations by
an Extended
Numerical
Method
In this
paper, an
extension
for the tanh-function
method is
proposed by
using an (α1,
α2,
..., αn,
β)− rational
transformation
method, n is
an arbitrary
integer. As
applications
and to
illustrate
the validity
of this
method, the
(1+3)-
dimensional
conformable
time and
space
factional
Burgers
equation,
and two
other
(1+3)-dimensional
conformable
fractional
evolution
examples,
that are
useful for
academic
purposes,
are solved.
More kink
and
generalized
traveling
wave
solutions
are obtained
and some
three-dimensional
solution
graphs are
presented at
the end of
this paper.
