PIPELINES' STUDIES -- NEW PROBLEM FOR GEOPHYSICS. ... From the century's beginning many thousand kilometers of various pipes and cables were stacked in ground on depth up to 5-6 meters. ... On our opinion to these methods resistivity sounding (fig.2) and profiling, potential of cathodic protection study and pipe tracing with magnetic antenna should be added. ... At studies of horizontal magnetic field's component with the help of magnetic antenna, directed normally to a pipe axis, maximum Fig.3. ...
... Three representative parameters characterizing the solar activity are sunspot number (W), 10.7cm radio solar flux (F10.7) and mean solar magnetic field value (SF). ... Practically persistent time series of these parameters are appropriate data sets for modelling and forecasting by means of Artificial Neural Networks (ANN). Methods of optimization of ANN input data sets and selection of training, testing and examination sets are discussed in the paper. ...

The beamer class Manual for version 3.06. \begin{frame} \frametitle{There Is No Largest Prime Number} \framesubtitle{The proof uses \textit{reductio ad absurdum}.} \begin{theorem} There is no largest prime number. \end{theorem} \begin{proof} \begin{enumerate} \item<1-| alert@1> Suppose $p$ were the largest prime number. \item<2-> Let $q$ be the product of the first $p$ numbers. \item<3-> Then $q+1$ is not divisible by any of them. \item<1-> Thus $q+1$ is also prime and greater than $p$.\qedhere
