Аннотация: In this paper an original approach to analytical decision making support based on on-line analytical processing of multidimensional data is suggested. According to Dr. Codd's rules, the effectiveness of data analysis significantly depends on the data accessibility and transparency of an analytical model of domain. The method of constructing a conceptual OLAP-model as an integral analytical model of the domain is proposed. The method is illustrated by the example of the scientific activities domain. The integral analytical model includes all possible combinations of analyzed objects and gives them the opportunity to be manipulated ad-hoc. The suggested method consists in a formal concept analysis of measures and dimensions based on an expert knowledge about the structure of analyzing objects and their comparability. As a result, conceptual OLAP-model is represented as a concept lattice of multidimensional cubes. Concept lattice features allow the decision maker to discover the nonstandard analytical dependencies on the set of all actual measures and dimensions of the scientific activities domain. Conceptual OLAP-model implementation allows user makes better decisions based on on-line analytical processing of the scientific activity indicators. В© 2013 Springer-Verlag.

Аннотация: In this paper a new approach to analytical decision making support based on on-line analytical processing of multidimensional data is suggested. The effectiveness of data analysis depends largely on the data accessibility and transparency of an analytical model of domain. As usual, analytical model of domain is a set of OLAP-models for solving particular problems. The method of constructing a conceptual OLAP-model as an integral analytical model of the domain is proposed. The integral analytical model includes all possible combinations of analyzed objects and gives them the opportunity to be manipulated ad-hoc. The suggested method consists in a formal concept analysis of measures and dimensions based on an expert knowledge about the structure of analyzing objects and their comparability. As a result, conceptual OLAP-model is represented as a concept lattice of multidimensional cubes. Concept lattice features allow the decision maker to discover the nonstandard analytical dependencies on the set of all actual analyzing objects. Conceptual OLAP-model implementation improves the effectiveness of decision making support based on on-line analytical processing of multidimensional data. В© 2012 The authors and IOS Press.

Аннотация: The problem of ionisation of atomic sodium in the field of resonance laser radiation is numerically solved taking radiative transfer into account. Seed electrons are produced due to the mechanism of associative ionisation, then they gain energy in superelastic processes (collisions of the second kind) and initiate the avalanche ionisation of the medium by electron impact. We studied the effect of secondary radiation on the laser pulse propagation upon competition between the ionising and quenching electron collisions with excited atoms, on the kinetics of ionisation-induced vapour bleaching, and the plasma channel expansion in the form of a halo.

Аннотация: The propagation of the resonance electromagnetic wave accompanied by gas ionization is considered. Plasma is formed through initial associative processes followed by the action of electrons which gain energy when colliding with the excited atoms. The change in the nature of the radiation propagation results from both a decrease in the ground state atom density and an increase in the probability of the upper state atom de-excitation. Concrete estimates are made for cesium. The degree of gas ionization and the wave propagation velocity of transparency are calculated. В© 1981.
