—This paper presents a modeling technique for output signal prediction of a waveguide probe when scanning a tilted long crack. The modeling technique establishes a cavity by placing a hypothetical conductive plane within the waveguide at some distance away from the probe–crack mouth. The position of the plane is iteratively changed until the appropriate(More)
A fractional order PID (FOPID) for a load frequency control (LFC) is presented in a three-area power system. FOPID controllers are designed the same way as PID controllers are, with the difference that FOPID controllers have five parameters in the controller that should be determined. That is why they have two more degrees of freedom for better tuning the(More)
—A great number of existing power transmission lines have aged throughout the world. A considerable proportion of them are located in the environments that exacerbate their corrosion and erosion process. In-time detection of defects necessitates the use of nondestructive testing (NDT) techniques. Scanning the lines with robots and helicopters are the(More)
A hybrid method is presented for modeling realistic ground penetrating radar systems to detect multiple underground conducting or dielectric targets. The model combines the method of momentpsilas solution of the frequency domain thin-wire electric field integral equation to treat the dipole antennas and the finite difference time domain technique to handle(More)
