This paper introduce the notion of
b-syndetic sets and give new results by
using the
work of W. Gottschalk (1955), H. Lee (1985),
D. Andrijevic´(1996) and S. Al-Kutaibi (1997).

In this paper, we define the concepts of a
closed ideal with respect to an element of
a BCH-algebra and a closed BCH-algebra
with respect to an element of BCHalgebra . We stated and proved some
theorems which determine the relationship
between these notion and the notions of
some ideals of a BCH-algebra.

Mixing property was classified in the
first book of topological dynamics
written by Gottschalk & Hedlund ,[4],
( 1955 ) as one of the regionally transitive
properties . It is concerned with the
existence of a compact subset K of the
phase group G of a topological
transformation group (X ,G,π ) such that
for every U ,V non empty open subsets
of X ,there exists a compact subset K of
G such that, for every
g ∈ K ⇒Ug ∩V ≠ φ
C
,
In this work we introduced new
different types of mixing ,and studied
there relations with other transitive
properties. Moreover we studied some
relations between them and recursion
dynamical properties such as periodicity ,
almost periodicity and recurrence. we
gave conditions to transfer some types of
mixing under suitable homomorphism.

Sorting has been a profound area for the
algorithmic researchers and many
resources are invested to suggest more
works for sorting algorithms. For this
purpose, many existing sorting algorithms
were observed in terms of the efficiency
of the algorithmic complexity.
Many algorithms are very well known
for sorting the unordered lists.
In this proposed algorithm, we
suggested a new algorithm for sorting
integers number depending on dividing
the input array to many sub-arrays (which
represents a vector or array with one
dimension), according to the number of
digits in each integer number, the relation
between sub-array elements is determined,
and this relation used to determines the
right location of each element in subarrays.
Collision may happen, which is solved
by moving elements in sub-array to next
location. Finally, all ordered sub-arrays
will be merged together to rebuild the
origin array. The proposed algorithm
compared with many famous algorithms
gives promising results.

In this paper, land use/cover
classification using fuzzy techniques
which involves several steps, from
designing the parameters of the
membership functions through
classification of the satellite image to the
refining the final product. To decide the
threshold parameters of membership
functions that lead to appropriate
classification of the scene, one band of
landsat-5 were investigated by the features
of the histogram of each area to be
classified. The results of fuzzy system
(Mamdani type) has been compared with
the classical method (* Maximum
likelihood classification *) and encourage
us to use this technique for other bands
with optimum rules for future works.

In this paper, we will study the
numerical solution of fuzzy initial value
problems using two methods, namely, the
least square method and the Adomain
decomposition method. Also, comparison
between the obtained results is made, as
well as with the crisp solution, when the
α-level equals one.

In this study we present five variables of
lecturer's evaluation in department of
community health nursing, college of
Nursing, Kufa university in Iraq for 2011.
The data is analyzed using completely
random design, LSD and factorial
Experiment to explain the significant
difference between all variables (scientific
,personality ,ability of evaluation and
ability of communication ) for each type
of evaluation. SPSS program (version 16)
was used throughout this study to analyze
the data and to generate various Tables .

The main goal of this work is to create
a general type of G – space , namely,
feebly Cartan G – space and a new type of
limit sets , namely, feebly limit sets
(x)
f Λ , J (x)
f
and, give some properties
and some equivalent statement of these
concept also we explain the relationship
among the definitions feebly Cartan G –
space and (x)
