    The phenomenon of scintillation of radio waves propagating through the ionosphere is reviewed in this paper. The emphasis is on propagational aspects, including both theoretical and experimental results. The review opens with a discussion of the motivation for stochastic formulation of the problem. Based on measurements from in-situ, radar, and propagation experiments, ionospheric irregularities a... View full abstract»

    Starting with post World War II studies of fading of radio star sources and continuing with fading of satellite signals of Sputnik, vast quantities of data have built up on the effect of ionospheric irregularities on signals from beyond the F layer. The review attempts to organize the available amplitude and phase scintillation data into equatorial, middle-, and high-latitude morphologies. The eff... View full abstract»

    Following an outline of electromagnetic transients in high-voltage power networks, together with their principal implications in relation to system overvoltages and the switching duty imposed on circuit-breakers, the paper develops a broad review of the now numerous analysis formulations and computer solution methods in this area of applied analysis in power systems. The perspective is one which e... View full abstract»

  • On minimum step response rise time of linear low-pass systems under the constraint of a given noise bandwidth

    Publication Year: 1982, Page(s):404 - 406

    If the step-response rise time of a linear low-pass system is to be a minimum under the constraint of a given noise bandwidth, the systems parameters should be so tuned that the step response is strictly free from overshoot. This conclusion is also true when the system bandwidth is defined as its 3-dB bandwidth. View full abstract»

  • Efficient algorithms for solving modified matrix equations of linear systems

    Multiparameter change in linear algebraic systems is investigated systematically by a parameter matrix decomposition of the modified system interaction matrix. Transformation of the corresponding modified response matrix to a parameter representation considerably reduces the computation of system response. Three highly efficient response change algorithms are formulated and critically compared. View full abstract»

    A new method of calculation of chain matrix for tapered ladder network is presented. This network is a special case of inhomogeneous ladder network. The theory of homogeneous ladder network is a starting point for the calculation of a chain matrix for a tapered ladder network. View full abstract»

    A few simple approximations are derived for erfc (x) by method of least squares (MLS). The detailed error profiles are presented. It is shown how these approximations are useful in extracting the inverse of erfc(x). Finally a simple approximation with overall relative root mean square error (RRMS) of less than one percent is presented. View full abstract»
