We present an investigation of the environment (≈ 600 kpc radius) of a pair of luminous z = 4.25 quasars, SDSS J1439−0034 A,B, separated by 33. An analysis of high-quality Subaru spectra of the quasars suggests that this configuration is indeed a physical pair and not a gravitational lens; the redshifts are slightly different (although marginally consistent with being the same), and the two spe...

In this article, a novel and accurate scheme for fault detection, classification and fault distance estimation for a fixed series compensated transmission line is proposed. The proposed scheme is based on artificial neural network (ANN) and metal oxide varistor (MOV) energy, employing Levenberg-Marquardt training algorithm. The novelty of this scheme is the use of MOV energy signals of fixed se...

Pixmotor is an image-based technique developed by Rhythm & Hues for adding realistic motion blur to a statically rendered image, using a pixel motion and a depth image, which are inexpensively generated by the renderer. The resulting motion blur is of sufficiently high quality to have seen extensive use in recent motion pictures, including Garfield: A Tale of Two Kitties and Night at the Museum...

This paper analyses two different approaches of fault distance location in a double circuit transmission lines, using artificial neural networks. The single and modular artificial neural networks were developed for determining the fault distance location under varying types of faults in both the circuits. The proposed method uses the voltages and currents signals available at only the local end...

Precise factors controlling the coevolution of deformation and topography in tectonically active landscapes remain poorly understood due to complex feedbacks between numerous possible variables. Here we examine the links between fault kinematics, emergent topography, and environmental factors on a global data set of active fault-driven mountain ranges (n = 41). Using simple regressions between ...

A method for determining the earth fault distance in high impedance grounded networks is presented here. With the transient processes having decayed in case of an earth fault, the grid tunes into a steady state error condition in which it can be operated initially. Starting out from the stationary earth fault condition a line model of a unilaterally powered feeder with one load based on a PI-el...
