Theoretical lattice structural model
# 09, September 2011
A.N. Bojko
This article continues the series of the author's works on mechanical systems modeling during process design. It is proposed to use a lattice model describing the product’s mechanical constraints. This model is defined as a partial order on the set of contractible subgraphs. It is shown that many design and technological solutions are described in lattice terms. A set of components that are coordinated relative to each other can be described as an act of a closure operator defined on the set of parts. The images also form a lattice operator which is defined as an algebraic structure.

Fuzzy-multiple modeling of regional labor market needs for human resources
# 09, September 2011
I.V. Ivanov, E.A. Lazebnaya
The article covers the approach to modeling indicators that characterize the need for human resources both at an individual enterprise and a regional labor market (RLM) as a whole, with the use of fuzzy sets. RLM need for human resources is based on criteria values aggregation received for each individual RLM enterprise participating in the study. For this the following were used: a criterion to assess the degree of using human resources on the basis of employment analysis of employees, and a criterion describing human resources motion at an enterprise. Analysis of the received values can be used to forecast future need for human resources.
Software For Optimum Design Based on SolidWorks API

M.V. Chugunov, Ju.A. Nebaykina
The work covers a method and its software implementation for the optimum design based on API SolidWorks. Optimization functions are approximated step by step by simplified analytical functions the analysis of which does not demand greater computing expenses. The application is realized as the AddIn DLL-module with COM-interface to SolidWorks. Thus SolidWorks is used by the program as a processor to define current parameters of the model and also as pre- and the postprocessor. To illustrate the work gif-animations are included in the paper.
Composition GLOTEON: glossary + thesaurus + ontology
# 09, September 2011
V.E. Klyukin
We consider the extension of an ontological model of knowledge representation in intelligent systems of computer text recognition. For the proposed extension a special term is introduced (GLOTEON): glossary +  thesaurus + ontology. Use of GLOTEON would increase the efficiency of text recognition both on the basis of an ontological model and on the basis of a domain model. The proposed extension would also extend the "ontological" approach to intelligent systems beyond computer linguistics.
Management of knowledge derived from text documents.
# 09, September 2011
I.P. Norenkov
Growing attention paid to methods of knowledge management tasks is caused by rapid growth of document databases and by difficulties connected with searching for the necessary information and its online processing. There appeared a lot of publications dedicated to automation of solving semantic search problems and information analysis. Nevertheless, approaches to automated solving the knowledge management tasks require further development and study. The paper includes a short review of recent approaches. An approach based on ontology clasterization is suggested.

# 08, August 2011
V.N. Hloponin, A.N. Tinigin
Hot rolling wide-strip mill (h.r. WSM) continue to reserve the leadership in the production of hot rolled strips. Transfer table between roughing and finishing trains the problematic place in the technological line of h.r. WSM where essential uneven cooling along the length of transfer bar. Passive methods heat insulating or reflecting are widely applied at continuous (3/4 continuous) h.r. WSM for cooling reduction of transfer bar don’t eliminate the mentioned phenomenon totally. Last years active methods of influence upon transfer bar temperature at transfer table began to appear in industry: active tunnel furnace Techint (Italy), pseudo-active panel Istok ML JSC (Russia). Heat and energy efficiency of these methods for holding transfer bar temperature are analyzed below.
