One of the principal applications of fuzzy logic is in control
system design. Fuzzy logic controllers (FLC) can be used to control
systems where the use of conventional control Techniques may be
Problematic .in this paper Fuzzy logic controller is
fabricated on
modern Field Programmable Gate Array (FPGA)Card to track the
sun to increase the energy generation efficiency of solar cells. Sun
Tracking Controller is tested using model designed by
Matlab/Simulink program. Finally we have compared with a
conventional perturbation and observation controller. Simulation
and experimental results show that performance of the fuzzy
controller with FPGA is better than the perturbation and observation
controller.
Sun movement considered one of the effective factor in human life, it should be studied in order to use or protect from it. sun path and its angles can be specified in hims city any time all year long, That can be done with Computer-assisted Architec
tural Design and Building Performance Simulator. Reaching for schedules, printed diagrams and digital files that can help architects in solar design process.
This study tries to know the rate of the deficiency of vitamin D experienced by Lattakian women as well as its accompanying diseases. It is conducted at a specific clinic in Lattakia in the period (2012-2013).
The study included a sample of 127 w
omen randomly chosen. It depended on laboratory results of the levels of vitamin D: normal rate, moderate deficiency, acute deficiency. It also depended on age group: Group1(20-50 years old): Group 2: (more than50 years old).
The study concludes that the rate levels are as follows: very high (84.26%), normal (15.74%), moderate deficiency (55.15)%, and acute deficiency (44.85%).
Symptoms based on age were as follows:
Group 1: clinical symptoms were more visible than diseases. The clinical symptoms were: 1-the muscular vatic (93.70%); 2 anxiety and depression (77.05%). Diseases were: 1-thyroied failure (12.5%), 2-hypertesion(6.25%).
Group 2: Diseases were more visible: The clinical symptoms were :1-anxiety (85.18%), 2-the muscular vatic (74.07%). Diseases were :1-cardiovasculardiseases (44.44%), 2-hypertension(37,03%).
