Phase Shifting Transformer has played an important role in electrical networks to improve their efficiency because it has the ability to control power flow in electrical transmission network that can lead to power loss minimization. PST technology is considered as mature technology which is used by transmission system operators. These transformers provide an integrated solution to control power due to the advantages of low economic and high reliability. In this research an exposure to the classification of phase shifting transformers and their application then a simple model for Phase shifting transformer is suggested without seeking in the details of transformer, this model presents the result for using PST via modeling phase shifting voltage, this model is performed using Matlab/Simulink program according to differential equation. Depending on the mathematical model which has been built in an Matlab environment we have a model shows the impact of this transformer through the representation of output voltage , results are verified using Neplan program via a case study demonstrated the role of this type of transformers in controlling power flow in transmission system achieving remarkable power loss reduction and improving voltage profile

Induction motors are the most widely used electrical motors due to their reliability, low cost and robustness. However, induction motors do not inherently have the capability of variable speed operation. Due to this reason, earlier dc motors were a pplied in most of the electrical drives. But the recent developments in speed control methods of the induction motor have led to their large scale use in almost all electrical drives. Out of the several methods of speed control of an induction such as pole changing, frequency variation, variable rotor resistance, variable stator voltage, constant V/f control, slip recovery method etc, the closed loop constant V/f speed control method is most widely used. In this method, the V/f ratio is kept constant which in turn maintains the magnetizing flux constant so that the maximum torque remains unchanged. Thus, the motor is completely utilized in this method.
This paper focus on studying the elastic of modified cement mortar by polyethylene (stress-strain) curve in order to have Young's elastic modulus, this made by tri-phases modeling that allow to determination the property of this item depending on t he property of it's three components individual. The validation of the proposed model has been studied extensively depending on a sample of cement mortar divided into two groups, the first one patterning normal cement mortar, second patterning modified cement mortar by Polyethylene witch substitute five percentage ratio of weight of sand by the same ratio of Polyethylene. Modified cement mortar is treated as composite of three components, Sand, Paste cement and Polyethylene. It's will be proposed models involving series, parallel and series-parallel coupling. This composite action is described by series-parallel model in which a portion of paste acts in parallel with sand and polyethylene and the remaining portion in series with this parallel coupling. Then according to the model we get Young's elastic modulus theoretically, reliance basic modulus factors of components. The proposed model is calibrated and verified by means of data set by experiment modulus results perform on cast samples in laboratory. It was found quite agreement of measured modulus factors experimentally versus theoretically.

Decision making process have to be much more accurate and careful. Therefore, decision makers depend on what-if analysis systems to predict an impact of a specific scenario. Usually, previous what-if analysis models in the literature have been direc ted just to predict an impact of a specific scenario. Therefore, our main goal in this approach is to enhance what-if analysis to suggest the best scenarios, in addition to predict their impacts. Affordable offers are one of the best ways to increase the revenue in telecom companies. Decision makers can predict a potential revenue before launching an offer, depending on what-if analysis system. This research depends on enhanced k-means algorithm to categorize customers into segments of the same behavior or usage.
