In this paper, we will design a Fuzzy Smith Predictor (FSP),
then we will model, simulate and analyze it using colored Fuzzy Petri
networks, then we will compare it with a conventional proportional
integral controller.
The main objective of this
research is to reduce the delay time
of the wind turbine system and to increase its reliability, in the other
side, to improve the response and stability of the operating point of
the mechanical energy and reduce vibration caused by the delay time
in the system.
The contribution of our research include building an artificial neural
network in MATLAB program environment and improvement of
maximum loading point algorithm, to compute the most critical
voltage stability margin, for on-line voltage stability a
ssessment,
and a method to approximate the most critical voltage stability
margin accurately. a method to create a (ARTIFICIAL NEURAL
NETWORK) approach.
This study was conducted at AL Assad University Hospital in Latakia in 2012. It was a prospective study of pregnant patients admitted Department of Obstetrics and Gynecology during the period between 1\9\2012 and 1\9\2013. These patients had regular
menstrual information and were in 37th week or more of gestation and did not have any disease in the mother or fetus affecting the growth of the fetus.
The study included 122 patients regardless of the mode of delivery. Each patient's information was documented: estimated gestational age by LMP (last menstrual period) and estimated gestational age by ECHO using (BPD : biparietal diameter, FL: femur length) during the 24-hour from delivery, presentation and amount of liquid by ECHO. Gestational age ranged between 37 and 41.5 weeks "with an average of 38.6 weeks" and a standard deviation of 1.1 weeks" by LMP.
Results showed almost convergent values based on all BPD and FL. There was also a stronger correlation between the ages of pregnancy estimated FL, LMP than BPD, LMP. Moreover, there was presence of a strong correlation between the ages of pregnancy estimated using BPD, FL and LMP when the presentation was breech. It was also observed that the presence of a good amount of liquid is necessary to estimate the age pregnancy ultrasound.
