تم في هذا البحث اجراء دراسة نظرية لسماحية العازل الكهربائية للمستحلب ، و تم وضع برنامج بلغة Matlab لدراسة سلوك سماحية المستحلب مقابل النسبة بين سماكة الطبقات المتشكّلة حول القطرة و نصف قطرها R. و لاحظنا من الرسم البياني أن مساهمة حد عدم التجانس في السماحية الكهربائية للمزيج تأخذ قيما في المجال المقابل لحجم الجسيمة في المجال عند قيمة ثابتة للتركيز C=0.01 ، كما تبيّن أن مساهمة عدم التجانس في السماحية تتناسب طرداً مع سماكة الطبقات المتشكلة، و عكساً مع أبعاد الجسيمات. يمكن تطبيق هذه الدراسة في مجالات متعددة كالمشتقات النفطية ، و المواد الصيدلانية ،و المواد الغذائية ، و المواد التجميلية و غيرها.
In this research, the relation which describes the electric permittivity of emulsion was theoretically found. After that, a Matlab code was used to study the behavior of mixed permittivity changes versus the ratio between forming layer thickness around particle to its radius. We noticed from the graph that the contribution of heterogeneous term in electrical permittivity take values in the range corresponding to particle size in the range at definite value of concentration C =0.01. In addition, the contribution of heterogeneous term in electrical permittivity is proportional with the forming layer and inversely with particle radius. This study has multi-field application as: oil products, pharmacy materials, nutrients and cosmetic materials

Research over the past years has focused on electromagnetic waves and meta-materials. These structures are designed to give electromagnetic properties that cannot be produced by traditional, well known natural structures. Meta-materials obtain their
electromagnetic properties from their structures, not from their components. Meta-materials have new properties that define different mechanisms for electromagnetic wave propagation. These materials have been studied theoretically and have been used in many applications, especially microwaves and photonic fields. This research depends on these kinds of material, explains them, and analyzes the electromagnetic properties that yield from putting columns from these slabs with negative permittivity and permeability coefficient (MMs) in a fractal distribution of a natural medium. This research also compares the resulting properties with the electromagnetic properties that yield natural materials distributed the same way. We use the HFSS simulator which depends on the finite element method for calculating transmission and reflection coefficient for these structures.
Electric energy is very important for sustaining the good life on the planet's surface, especially since civilization has become associated with this type of energy. Solar photovoltaic (PV) is one of the most suitable applications for converting sunl
ight into electrical energy. The appropriate use of solar energy is an important topic for reducing dependence on fossil energy sources that are used to generate electricity, and thus reducing the emissions of greenhouse gases on the planet's surface. Globally, because of environmental conditions, other methods of generating energy being searched for that are less harmful than traditional methods, which rely on a large percentage of them on generating stations that run on fossil fuels. This research discusses electrical power generation using solar energy cells and the effect of these cells on the Syrian electrical grid so that a study of a solar energy farm project provides the data required when working on implementing such a project, and these data are voltage control, load flow, total harmonic distortion coefficient levels. To implement such a project, the model must be designed and we chose the ETAP program for that.
Operating the electrical power systems at normal conditions is our goal always. This
is what represents the ideal state of electrical power system work. Hence, the electrical
power system work in case of insufficient electrical power requires avoid
ing since it leads
to big losses in national economy.
These losses could be huge when we talk about connection borders between systems
as per overload frame, because of lack of electrical power request. The impact of these
conditions could be noticeably decreased at a reasonable limit of electrical power request.
When we find out the optimal solution of electrical power systems operation and the
communication lines between them while considering the losses of consumers
disconnecting that guarantee the stability of loads. Finally, it is so at full use of maneuver
(available cases) spare power properties when applying the instant correction of regime.
This paper studies the basic approach to solve these issues which imply the reliability
definitions.
After that automation electrical power transfer stations towards to
use intelligent electronic devices that are performing multiple
functions : process protection, monitoring, control and use
private companies manufacturers of equipment communicat
ion
protocols, so that need to build electrical smart grid that coordinate his parameters and support his devices.
Search begins definition electrical smart grid and its importance,
and includes the benefit of this electrical smart grid, the requirements and the careers then the specifications of electrical
smart grid, at the end of the search: we compare between the
electrical power transfer stations in electrical traditional grid and
electrical smart grid.
A reliable and continuous supply of electrical energy is necessary for the functioning
of today’s complex society. Because of the increasing consumption and the extension of
existing electrical transmission networks and these power systems are oper
ated closer and
closer to their limits accordingly the possibilities of overloading, equipment failures and
blackout are also increasing, furthermore, we have an additional obstacle which is that
electrical energy cannot be stored efficiently, so, electrical energy should be generated only
when it's needed.
Due to the fact that world is facing a lack of oil reserves and the difficulties related to
have alternative sources to generate electrical power, then, electrical load forecasting is
considered as a crucial factor in electrical power system either from economical or
technical point of view on both planning and operating levels.
This research introduces a short term electrical load forecasting system by using
artificial neural networks with a simulation in Matlab environment in addition to an
interface for the system and all that is depending on previous load data and weather
parameters in Tartous province.
