Nonlinear propagation of light pulses can excite dispersive waves anchored at frequencies determined by the chromatic dispersion curve. In this work, conditions enabling dispersive-wave self-frequency shift over distance are analytically derived in normal regime. Importantly, novel, to best our knowledge, scenario is not found solving complex dynamics pulse, but studying evolution nonlinear and...

in this survey, asbestos fiber levels within the breathing zone of employers and in the environment of an asbestos-cement factory were monitored on membrane filter and counted by phase contrast optical microscope considering length/diameter>3:i (asbestos international associational method). the plant was fairly old and utilized both white (chrysotile) and blue (chrocidolite) asbestos. in each w...

In this paper, a comparative study of performance of some parametric and nonparametric EWMA control charts for detecting the process mean shift is considered. In section 2, we briefly describe each of the various EWMA models that are taken into account in our present study, Viz. the Parametric X -EWMA and Nonparametric Grouped Signed Rank (GSR)-EWMA, for the purpose of comparative study. In Sec...

and conjectured that F I 12.32, for all binary sequences, with the exception of the Barker sequence of length 13, for which F = 14.08. In a recent paper Golay [5] argued that the merit factor of Legendre sequences, shifted by one quarter of their lengths, has the highly probable asymptotic value 6, but he did not prove this. For maximal-length shift register sequences, one can see from [6] that...
