Analysis of transport flows in a megapolis road network from the data of a mobile network operator

Fundamentals of a method for the analysis of transport flows in a megapolis vehicle network from the data of a mobile network operator are considered. A model allowing an approximate calculation of the motion velocity in sections of a megapolis road network and estimation of the congestion of these sections is proposed. The method is implemented on the GIS GeoTime 3 platform. Experimental results for the road network of Moscow city and Moscow region are discussed.

Radiation of a travelling-wave antenna in plasma in the whistler frequency band

The far field, the radiation pattern, and the radiation impedance of a traveling-wave antenna oriented in plasma along the external magnetic field in the resonance region of the whistler frequency band are studied. It is shown how the main characteristics of the antenna depend on its length and the current propagation constant along the antenna wire.     

An approach to the automatic prediction of earthquakes

A new approach to automatic prediction of earthquakes is considered. The seismotectonic processes are represented using spatio-temporal fields. The parameters of prediction by several fields are the linear predictive function, the value of the alarm decision threshold, as well as the size of the spatio-temporal alarm domain. The considered approach is not bound to a specific data type. Simulation results show that the automatic prediction is available with the use of the Internet catalogues of earthquakes, feasible and rather efficient.
