A Probabilistic Approach to Quantify the Value of Information of 4D Seismic Projects

To solve the problem of information security management the method was proposed that allows determining the degree of importance of confidential documents of the organization. The urgency of the proposed algorithm was substantiated taking into account the requirements of the legislation of the Russian Federation in the sphere of information security. The stages prior to the formation of the list of confidential documents of the organization were described. A review of the main documents of the legal and regulatory framework was carried out including documents relating to the state regulation of relations in the sphere of information security. The classes of protected information for the accessing categories were considered. The criteria changes of the value of information in the process of time were represented. The algorithm of formation of the list of confidential documents of the organization based on the properties of information was offered. The algorithm is based on an expert method of pair comparison of alternatives. The result of the use of this method is a number of confidential documents, ranked in descending order of importance. For each document the weighting factor of importance can be calculated. The verification stage of the degree of expert consistency was included in the methodology to eliminate the use of erroneous expert data. The application of the methodology is illustrated by a calculated example.

Real Performance

The assessment of the service life of concrete structures using the durability design approach is widely accepted nowadays. It is really encouraged that a simulation model can resemble the real performance of concrete during the service life. This paper investigates the concrete carbonation through probabilistic analysis. Data regarding Indonesian construction practice were taken from Indonesian National Standard (SNI). Meanwhile, data related to Indonesian weather condition for instance humidity and temperature are taken from local Meteorological, Climatological, and Geophysical Agency from 2004 until 2016. Hopefully the results can be a starting point for durability of concrete research in Indonesia.

AbstractIn this work we analyze the behavior of a nonlinear dynamical system using a probabilistic approach. We focus on the coexistence of solutions and we check how the changes in the parameters of excitation influence the dynamics of the system. For the demonstration we use the Duffing oscillator with the tuned mass absorber. We mention the numerous attractors present in such a system and describe how they were found with the method based on the basin stability concept.
