The E ect of an Interline Power Flow Controller (IPFC) on Damping Interarea Oscillations in Interconnected Power Systems
(Sharif University of Technology, 20080401)The e ect of an Interline Power Flow Controller (IPFC) on damping low frequency oscillations has been implied in some papers, but has not been investigated in detail. This paper investigates the damping control function ...

E ect of anisotropy and piezoelectricity on the forcefrequency coe cient of ATcut quartz crystals
(Sharif University of Technology, 20161001)A clear understanding of forcefrequency e ect is essential for enhancing the accuracy of quartz crystal resonators and sensors. Several analytical models have been developed to predict the frequency change of piezoelectric ...

E ect of AntiVortex Plates on Critical Submergence at a Vertical Intake
(Sharif University of Technology, 20100401)One of the sources of disturbance at intakes is the occurrence of freesurface vortices with an air core. The most common solution for avoiding airentrainment is the use of antivortex devices and, especially, plates ...

E ect of Different Configurations on 3D Analysis of Flow Through Stay Vanes and Guide Vanes of a Francis Turbine
(Sharif University of Technology, 20101201)Stay and guide vanes (distributor) are essential parts of a turbine. They are used to control the ow rate and to appropriately transfer the ow momentum to the runner. In this work, ow through the distributor is ...

The E ect of Geosynthetic Reinforcement on the Damage Propagation Rate of Asphalt Pavements
(Sharif University of Technology, 20090201)Abstract. There are several approaches for modeling the fatigue life and damage of asphalt pavements, such as stressstrain and damage mechanics. In this research, a simple mechanistic approach is used to explain the ...

The E ect of Heavy Fermion or FSemiconductor Systems on GdIntermetallic Systems
(Sharif University of Technology, 20090201)Abstract. Based on the instability of magnetic behavior through the concept of local exchange and hybridization, a new class of heavy fermion is constructed with a stable local magnetic ion, Gd". The lattice constant, ...

The e ect of indicial equations in solving inconsistent singular linear system of equations
(Islamic Azad University of Arak, 20120101)The index of matrix A in Cn. n is equivalent to the dimension of largest Jordan block corresponding to the zero eigenvalue of A. In this paper, indicialequations and normal equations for solving ...

E ect of Payload Variation on the Residual Vibration of Flexible Manipulators at the End of a Given Path
(Sharif University of Technology, 20090701)Abstract. In resttorest motion, the gripper of the exible manipulators vibrates not only in the duration of the tracking but also after reaching the goal point. This vibration, which is called residual vibration, ...

E ect of Permeable Contacts on the Performance of a GasOil Gravity Drainage Mechanism in a Stack of Matrix Blocks
(Sharif University of Technology, 20080701)In the gas invaded zone of a well fractured carbonate reservoir, gravity drainage mechanism plays the main role in expelling oil from dense, low permeability matrix blocks. Whenever the active mechanism is gravity drainage, ...

E ect of Reduced Frequency on the Aerodynamic Behavior of an Airfoil Oscillating in a Plunging Motion
