Efficiency investigation of virtual particles and experts command algorithms for cluster architecture
# 2, February 2007
“Experts command” and “virtual particles” algorithms used for artificial neuron network training, as well as their concurrent implementation at cluster architecture with the use MPI functions library are examined in the article. Outcomes of the experiment carried out on the basis of Krasnoyarsk State Technical University cluster are set out.
Requirements task to the output impedance of the independent object power-supply system
# 2, February 2007
     Definition method of output impedance admissible values of the independent object power-supply system at early design stages in different making conditions of electric consumption channels is described. Way of lowering of the requirements to the output impedance of the power-supply system is offered.
About the task of development of the logical-linguistic model of carbonizing column
# 2, February 2007
In this article on basis of fuzzy logic stages of development of a model of a carbonizing column being used in producing soda ash by ammoniac method are considered.
Completed tables conversion to the second normal form
# 2, February 2007
There is made an example of the relation not satisfying the third normal form in the article. Informal and then formal algorithms of functional dependency detection are proposed. The informal algorithm of functional dependency exclusion is proposed. Manipulation sequence with the relation for its cast to the 3rd normal form is demonstrated by way of an example. Application features of legacy database design tool for not great dimension relations cast to the 3rd normal form are considered.
Completed tables conversion to the first normal form
# 2, February 2007
The algorithm of deliverance from complex attributes is proposed in the article. Application features of legacy database design tool for not great dimension relations cast to the 1st normal form are considered. The algorithm of subheadings exclusion inside a table is demonstrated by way of an example. The algorithm of internal subheadings exclusion is proposed. Application features of legacy database design tool for internal subheadings exclusion in not great dimension relations are considered.
Formation of system of insurance protection at industrial enterprises
# 2, February 2007
There are considered problems of creation of the system of insurance protection of industrial enterprises in the article. The positive and negative aspects of using insurance as a mechanism of risk management are disclosed. The purposes and principles of functioning of the system, features of strategy of the industrial company in the field of maintenance of insurance protection, practical experience of “Lukoil" company are analyzed.
