The research was made at particular cow's station in near Safita city
at Tartous, in the period between May 2012 and October 2014.
of the dairy cows in two experiences at 48 The study took place at
Summer and Winter, each experiment included / 24

converged in the weights and the expected date of calving in tow

This research includes a simulation of optical code division multiple access system
transceiver (OCDMA) of the spectral amplitude coding (SAC). The study investigates the
effect of the pulse generator type used in the transmitter SAC-OCDMA of direc
t detection
technique and the effect of the length of the optical fiber on the signal quality factor (Q)
and on the bit error ratio( BER) . In addition a comparison is made between the SACOCDMA
system of direct detection technique and another one of complementary
subtraction technique in terms of signal quality factor and the bit error ratio when using
the same parameters for both systems.
Scientists nowadays increased their interest in artificial intelligence because
of the rapid development in the modern age. This development increased
the complexity of systems in order to consent society rapid needs in getting
systems of better r
eliability and high performance.
Artificial Intelligence solved many difficult and sticky problems.
We are going to define the genetic algorithms(GA) which is one of the
artificial intelligence branch because of its ability to solve many complex
problems in Different scientific aspects either in computer science[8] or
operational research and image processing[7] or social science[9].
In this essay, we used GA to find the maximum value of continuous function
within a limited rang to study the effect of some of the most important GA
parameters on the performance and accuracy of the results. We noticed the
effects of probability of mutation, population size and the number of the
repeated operations on the results accuracy and execution time in choosing
the Roulette Wheel Selection procedure. After that, we compare
between the Roulette Wheel procedure and the Elitism Selection procedure.
