ترجع صعوبة دراسة طرائق تحليل الانحدار المتعدد إلى فهم و تفسير العلاقات المتشابكة بين المتغيرات التي تؤثر في الظاهرة المدروسة والى ضخامة البيانات التي يجب تحليلها و بخاصة وجود بعض من هذه البيانات الشاذة . لقد قمنا في هذا البحث بدراسة و معالجة البيانات الشاذة الموجودة في بيانات نموذج الانحدار الخطي المتعدد في حالة وجود اثنين أو أكثر من معاملات هذا النموذج غير معنوية ، و أوجدنا خوارزمية لحل مشكلتي وجود البيانات الشاذة من جهة و حل مشكلة معنوية نموذج الانحدار و عدم معنوية معامل أو أكثر من جهة أخرى .
he problem with study of the ways of multiple regression analysis is related to e to the understanding and the explanation of the complicated relations among variables which affect the studied phenomenon and the huge amount of the used data in particular some of this outliers. In this research we have studied and treated the outliers in case of having two or more non-significant parameter and we have made anew algorithm to solve the phenomenon outliers on the one hand and solving the problem of the significant of multiple regression.

In this research ,we studied the problem of multicollinearity among
independent variables in the multiple regression model this matter
leads to a mistake in one of the essential conditions of the multiple
regression model and getting incorrect res
ults.
At the beginning we have introduced documented theoretical study
of the kinds of the multicollinearity and of the reasons of the
problem of the multiple regression model and some methods to
discover them.
In addition to this we mentioned some methods that treat the cases of
multiple regression model then we introduced a new method to treat
multicollineartiy and apply it to an example .
In this method we have dealt with multicollinearity on the hand and
solved the problem of discrepancy between the significant of the
regression model and the non-significant of one or more coefficient.
In this paper, we presents a solution for those problems by using (CAN)
protocol in ATM networks due to many features such as the priority of
access and lose-free bus arbitration. We designed a new application layer
for using (CAN) in ATM network.
Then we compared this proposal
pattern with the current ATM network by using MATLAB.
n this research, we are studying the possibility of contribution in solving the Vehicle Routing Problem (VRP), which is one of the optimization problems that, because of its Real Life applications, has attracted a lot of attention at the present tim
e. It is a problem of the NP-hard type. However, because of the complication of polynomial time there is still no algorithm providing us with the optimal solution of this problem. All the used algorithms give solutions that are close to the optimal one .
In this research, we will present the Hybrid Algorithm (HA) in two phases .In the first phase the Sweep Algorithm (SW) is applied, and in the second one the Ant Colony Algorithm and the local search 3-opt are applied. we will then compare the quality of the solution resulted from this hybrid approach with the results of well-known standard tests to determine the effectiveness of the presented approach .
This study was conducted at the farm of Faculty of Agricultural-Kharabo as
an intensive planting during 2011 and 2012 growth seasons. Using RCB design
with two replications to study some genetic indices and simple linear
correlation between yield
and quality traits of 79 families selected from Sh
population, improved by Full-sib selection. Results revealed that traits, silking
days, protein percentage and oil percentage were affected by additive gene
action while plant height and starch percentage were affected by non-additive
gene action. Results also revealed that grain yield showed positive significant
correlation with starch percentage (r=0.94*) and negative significant
correlation with plant height (r=-0.95*) and protein percentage (r=-0.52*)
indicating that less selection cycles are needed to improve families with high
yield and starch percentage contents with early silking days (intensive planting)
and medium plant height (machining cropper).
The actual effect of unplanned transition of rural environment with its different
components towards urban areas had played a big role in giving the gray tincture on the
housing reality of Syrian cities in general, which in turn released a problem
that faced
planners to solve as one of the most important priorities through concentrating on the
possibility of selective elevating of positive specifications of the rural environment as a
large effect contributing factor in solving the housing problem through suggesting a group
of helping solutions by implementing them as a developing type with a rural quality in
actual stopping of housing problem.
