Аннотация: The classic approach to calculate the electrostatic field penetration, from the Earth's surface into the ionosphere, is to consider the following equation del. ((sigma) over cap del Phi) =0 where (sigma) over cap and Phi are the electric conductivity and the potential of the electric field, respectively. The penetration characteristics strongly depend on the conductivities of atmosphere and ionosphere. To estimate the electrostatic field penetration up to the orbital height of DEMETER satellite (about 700 km) the role of the ionosphere must be analyzed. It is done with help of a special upper boundary condition for the atmospheric electric field. In this paper, we investigate the influence of the ionospheric conductivity on the electrostatic field penetration from the Earth's surface into the ionosphere. We show that the magnitude of the ionospheric electric field penetrated from the ground is inverse proportional to the value of the ionospheric Pedersen conductance. So its typical value in day-time is about hundred times less than in night-time.

Аннотация: It was shown the technique of seismic hazard assessment based on comprehensive use of methods of seismic microzonation. This technique consists of four steps. The first step is to collect geological, seismological, geophysical and topographic information. Each layer according to geological engineering survey and geophysical work are assigned physical and mechanical properties (density, limit shear stress) and the P-And S- wave velocity. Next (step 2) after visualization and examination input data using GIS technologies 3D modelling of the geological environment is performed (it is created a grid each point of which is referred to coordinates of the site). The number and depth of soil are set in each point based on geological drilling data. Then (step 3) at each point seismic intensity are calculated using instrumental methods including the method of acoustic impedance and computer simulation (GRUNT program). At the last stage according to the analysis of the results of theoretical and instrumental methods seismic microzonation map are created using GIS technologies. The procedure of constructing maps uses different methods of selection areas with the same seismic hazard (kriging, spline interpolation).

Аннотация: Исследование посвящено разработке алгоритмов для аппроксимации данных наблюдений сложных природных процессов и включает в себя несколько подходов, сочетание которых позволяет аппроксимировать сигналы различной сложности и находить в них скрытые закономерности. Рассматриваемые данные представляют собой данные специ ального вида: наблюдения систем геомониторинга и результаты экспериментальных исследований опасных явлений сейсмической природы. Использование полученной информации о скрытых закономерностях позволяет более эффективно решать задачи восстановления пробелов в данных, экстраполяции сигналов и локального прогноза.
The study focused on the development of algorithms for approximation of observational data of complex natural processes and includes several approaches. The combination of approaches allows to approximate the signals of different complexity and find hidden patterns. The considered data are the data of a special kind: observation of geomonitoring systems and results of experimental studies of natural seismic hazards. The use of the information about the hidden patterns allows you to more effectively solve the problem of recovering gaps in the data, extrapolation of signals and local forecast.

Аннотация: Почему технологии безопасности не всегда успевают за развитием прогресса? И что чаще становится причиной аварий - неисправность техники или безалаберность человека? На эти и многие другие вопросы корреспондента газеты «Наш Красноярский край» Бауэр И. отвечает Лепихин А.М., ведущий специалист в области теории безопасности и риск-анализа сложных систем, эксперт в области промышленной безопасности и оценки риска аварий и чрезвычайных ситуаций природного и техногенного характера.
Why do not safety technologies always catch up with progressive development? And what does more frequently become the reason of accident: faulty equipment or human negligence? These and many other questions are answered by Mr. Lepikhin A. M., leading expert in the fi eld of safety theory and complex systems risks analysis, expert in the fi eld of occupational safety and risk assessment in emergency situations of natural and man-caused nature, in his interview to Bauer I., correspondent of newspaper “Our Krasnoiarsk Region”.
