يقدم هذا البحث دراسة تفصيلية و تصميما عمليا لبناء و برمجة و تنفيذ منظومة لاستقبال الرسائل القصيرة المرسلة من هاتف خلوي أو أكثر إلى شريحة SIMالموضوعة ضمن دارة GSM-MODULE المتصل بدوره مع متحكم أصغري يقوم بترجمة هذه الرسالة و إظهارها على مصفوفة ضوئية.
This Research presents a detailed study and practical design for the
construction, programming and implementation of the system to
receive SMS messages sent from a mobile phone or more to the
SIM card placed with in the circuit (GSM-MODULE) connected in
turn with a microcontroller which translates and shows this message
on the optical matrix.

The main goal of this search is to design maximum solar power batteries charging
system, Maximum power point tracking (MPPT) system is used in the photovoltaic (PV)
system consisting of a buck-boost Direct Current DC/DC converter, which is controll
The DC sources like fuel cells, solar cells, storage units need to
raise its output voltage in order to match load requirements. So often these systems are equipped with Power Electronics
techniques in general and DC-DC booster converters in partic
The paper begins with an introduction that describes the concept and
importance of power system security. The mathematical model is built
depending on both the linear load flow technique and the sensitivity
factors for line and generation outages.
A reactor was designed to produce and rise the productivity of biogas
during anaerobic treatment of cattle dung.
It had a size of 32 cubic meters, constructed and installed. The material used
was a sheet of metal, the unit was put over the land.
This research is centered on design of a serial industrial manipulator with 4 degrees
of freedom(4-DOF) in order to manipulation on production linesand packaging tasks of
