The development of gas turbine needs to studying and development each of its components. In this paper we will focus on the study of the compressor used in gas turbines. So we can study it we will be using mathematical modeling, which aims to find a mathematical description of the system studied and study the dynamic behavior of it in order to improve his performance, and use mathematical modeling to save time and cost at the improvement and development of products or in the case of the creation of new products through simulation that enrich us all costly and timeconsuming testing stations. Also it helps us to clarify the physical phenomena or unwanted effects and enable us to determine the full parameters required in accurate design.

Gas turbines are used as main engines to convert fuel energy into mechanical energy used to move the generator and thus produce electrical power at the power plants. When you use a gas turbine in the power plants, it must maintain a constant speed of the turbine and thus fixed frequency output of the current also must maintain the parameters of the turbine such as pressures and temperatures at the limits and thus extend the life of the turbine components and increased efficiency. there was a need for the design of control systems maintain a constant speed of the turbine and to avoid operating at others and allowed values. In this research, we modeled the gas turbine and solving the model using MATLAB/ SIMULINK program, and then design a proportional integral differential controller for gas turbine operating In Gandar Station
This research includes a set of mathematical models for simulating the financial activities. Worked models are determined to approve the form of inflows to the bank and outflows. We tried to study different types of banks, and performed some condi tions to make sure that the bank is working in stabilized situation. Furthermore, we identified the factors affecting the achievement of stability. These models allow more flexibility in the discussion and analysis of banking operations, helping to discern periods approaching the crisis and draw attention to the overall status of the bank. Analyzing these models gives additional time to control withdrawal and take the necessary decision at the time.
This study aims to find the best indicators representing higher education components using the method of multivariate statistical analysis represented in a manner factor analysis, and create a mathematical model that connects the principal componen ts representing higher education and the rate of economic activity in Syria using multi- linear regression analysis. A descriptive analytical approach is used in this study. The most important results obtained state that the principal components that belong to higher studies and intermediate institutes have a positive impact on the rate of economic activity of manpower, whereas principal components that belong to students of state universities and higher institutes have a negative impact on the rate of economic activity.
Due to the importance of water, and the increasing of demand at the present time due to the tremendous development in all spheres of economic and social life, and as the evaluation, planning and management of water sources, one of the important top ics in human life, especially in areas with scarce rainfall or where rainfall distribution is poor or irregular so cannot be used for different purposes. From here, the importance of the research in forecasting rainfall in the Husn Suleiman station, comes, and to achieve this goal the data of time series for the average annual rainfall precipitation been used in Husn Suleiman station which located in the province of Tartous on longitude 36 ° 15 ' andlatitude 34 ° 56', for the period between 1959-2011, The methodology of "Box – Jenkins" been used in the study, this methodology relies on finding future forecasts from original data series. Also,the applications “MINITAB, EXCEL” have been used in the statistical side and the preparation of the study results. As a result, the study found that rainfall value in the 'Husn Suleiman station' decreasing, this decline amounted to 3.7 mm per year during the monitoring period. Also, the appropriate (ARIMA) model for the series was build after it passed the various statistical tests are required, and founded that ARIMA(1,0,0) model is a good representation of the data and the ARIMA(4,1,5) model is the right model to forecast future rainfall.
This study aims to find the best social and economic factors that affect the number of students in higher education using the descriptive analysis approach, and find the mathematical model that connects the principal components representing the socia l and economic factors and the number of students in higher education in Syria. The most important results that have reached were the principal components representing the social and economic factors, after doing the orthogonal rotation and was representing the first component (number of members the labor force that are gainfully) employed, the number of population per health doctor, number of members, the labor force that are self-employed, number of members the labor force that are unmarried, number of population per dentist, higher education budget, and number of nurses. And the four thcomponent (number of members the labor force that are married), both components affected positively on the number of students in higher education, the second component (economic activity rate of the human power, average number of people per pharmacist, number of members the labor force that are gainfully unemployed, the third component (number of members the labor force that are divorced and widowed) affected negatively on the number of students in higher education.
