تعطي أنظمة البث التلفزيوني التي تستطيع إعادة انتاج الصورة ثلاثية الأبعاد فكرة أفضل عن المناظر المتلفزة و تحسن الانطباع الفني و تجعل عملة استعادة الصور أكثر واقعية، و يشعر المشاهد بأنه موجود في موقع التصوير، و تتزايد الحاجة في أنظمة التلفزة إلى إعادة انتاج الصور ذات البعد الثالث. و من أجل تحقيق التآلف بين النظامين ثنائي و ثلاثي الأبعاد، يجب أن يكون عرض حزمة القناة أكبر مرتين من عرض القناة المستخدمة في أنظمة البث التقليدية. يهدف البحث إلى إيجاد وسائل و طرائق تسمح بتخفيض عرض الحزمة المطلوب لمثل هذه الأنظمة ثلاثية الأبعاد الملونة دون الإضرار بنوعية الصورة.
Stereoscopic broadcast Tv systems,That is,Those capable of reproducing a Three-dimensional picture,give a better idea about The televised scene,enhance artistic impression,and make The reproduction more realistic so That The observer has The sensation of being actually present at The scene of action. For a compatible 2-d/3-d colour Tv system The channel bandwidth should be twice That of The standard broadcast Tv channel. The search for ways and means of reducing The required bandwidth without an impairment in The quality of The colour 3-d picture is a major direction in work or such systems.

As oil spells, it is important to act as quickly as possible in order to minimize
damages that can affect people and natural life. Thus, for the necessary operations to be
done on time following an accident, numerical simulation of oil spell is an
essential tool.
The purpose of this paper is to develop a 2-D numerical model for the main operations
that control and affect the trajectory and fate of an oil spill. Two additional operations had
been considered, those are evaporation and dissolution which lead to lose some of the
spilled oil even in air or water column. Afterwards, oil spill scenarios had been created and
spreading of an oil spill, whose density and initial position are known, had been examined.
Using MATLAB, flow simulations had been made and results had been discussed.
In this paper we study some classes of partially pseudo symmetric contact
three-manifolds .
In sections 3 −1 and 3 − 2 we find necessary and sufficient conditions for
a contact metric three-manifolds to be partially pseudo symmetric of the first
and second type respectively .

In this article we study two classes of contact metric three manifolds,
where first we investigate the necessary and sufficient condition for the contact
metric three manifold to be partially pseudo- Ricci-symmmetric manifold of
constant type.
We
find also two relations that the 3-dimensional (k,m,n ) _ contact
metric manifold has to satisfy to be partially pseudo- Ricci-symmetric manifold
of constant type.
In this article we study the contact metric three-manifolds M 3 satisfying
certain curvature conditions especially ξ (λ ) = const.
