The possibility to apply long-term regional series to reconstruct the Earth's global temperature in the past is considered. It is shown using symbolic analysis methods that significant (on the so-called order patterns) are relations of time series of St. Petersburg temperature with certain regional and global series. New sets of global temperature reconstructions, starting from the mid-18th century, are constructed on the basis of the previously proposed MSR and DPS methods. © 2013 Pleiades Publishing, Ltd.

This paper proposes an algorithm that creates a digital signature in a nonpositional polynomial notation and forms three surplus residues modulo one extension polynomial base number. Such a signature allows for single-error detection and correction (which is shown to be a unique procedure) and multiple error detection. A formula of cryptographic security is obtained for such a digital signature. © 2012 Springer Science+Business Media, Inc.
