Lagrangian Systems with non-smooth constraints

The Lagrange-d'Alembert equations with constraints belonging to $H^{1,\infty}$ have been considered. A concept of weak solutions to these equations has been built. Global existence theorem for Cauchy problem has been obtained

AbstractThis article contain comprehensive data of completing the functional, complementary unified information model, based on the technology of building information modelling for creation city environment through the whole lifecycle of the building. Each stage of lifecycle contains its own functional information as a part of unify complementary information model. Complementary unified information model for the executive stage of engineering to complete the documentation are also describe. Complementary unified information model for the stage of facility management presented within the model of life support systems including processes of utility management

BIM-Technology in Tasks of the Designing Complex Systems of Alternative Energy Supply

AbstractArticle is devoted to the use of alternative energy, the development of which in recent years has been to acquire innovative. The authors investigate the existing methods of calculating automated supply systems for individual low building based on solar panels, wind power stations, geothermal systems separately and in combination, are considering Building Information Model (BIM) technologies that can be used in automation engineering design of such systems

MATHEMATICAL MODELING OF EXPERIMENT ON BERKOVICH NANOINDENTATION OF ZRN COATING ON STEEL SUBSTRATE

In the present paper the experiment on Berkovich nanoindentation of ZrN coating on steel substrate is modelled using the proposed effective mathematical model. The model is intended for describing the experiments on indentation of samples with coatings (layered or functionally graded). The model is based on approximated analytical solution of the contact problem on indentation of an elastic half-space with a coating by a punch. It is shown that the results of the model and the experiment are in good agreement

Extracting information from sequences of financial ratios with Markov for discrimination : an application to bankruptcy prediction

In this paper, we propose a method that extracts information from sequences of financial ratios and investigate the usefulness of this information for bankruptcy prediction, which constitutes an important class of financial services. We use the annual financial reports available from an external financial information services provider to extract predictors based on the Markov for Discrimination (MFD) methodology. These predictors are used as inputs in a binary classification model, which applies logistic regression to estimate the odds of bankruptcy. The results suggest that MFD-based predictors can achieve substantial predictive performance in terms of the AUC and the 5-percent predictive lift, which are two relevant performance metrics in our case

Minimization of the competitive risk of the tax system for improving public administration at national and regional levels

The article is devoted to the problem of tax risks of the state, which are described from three standpoints: as damage; through a combination of factors that define them; and from the standpoint of the probabilistic nature of their implementation. It is underlined that the competitive risk of the tax system is closely related to the process of tax competition. The country tax competition is illustrated by the experience of the European Union member states in reducing corporate income tax rates during the period of the European Union expansion in 2004 and 2007. The statistical data are provided to confirm the trend of the reduction of tax rates by the EU member states in the context of economic integration. The experience of the regions of the Russian Federation is described as an example of tax competition at the regional level. The option of assessing the scale of regions’ introduction of tax competition tools available in the conditions of modern Russian model of tax federalism is proposed. The comparative analysis of introduction of tax competition tools by regions and advance of the tax revenue growth over the growth of the regional economy is carried out. The absence of an unambiguous relationship between the scale of the introduction of the tax competition tools and the growth of tax revenues is shown by the example of the regions of the Central Federal District. The absence of such dependence is determined by similar taxation conditions in the regions of the Russian Federation, which describe broad prospects for the development of tax competition.peer-reviewe

FINANCIAL CONTROL AS A CATEGORY

The article reveals the basics of “financial control” as a category. The main attention is concentrated on the “control” itself (asa term), multiplicity of interpretation of“financial control” term and its juristic-practical matching. The duality of financial control category is detected. The identity of terms “financial control” and “state financial control” is justified. The article also offers ways of development of financial control juristical regulation

INDEPENDENT AUDITING OF PUBLIC EXPENDITURE AS A TOOL TO IMPROVE THE STATE FINANCIAL CONTROL

El control financiero estatal (SFC) es una parte integral de la administración pública. Su objetivo principal es identificar las desviaciones de las normas, las violaciones de los principios de legalidad, eficiencia y ahorro de recursos lo antes posible. Esto permite la adopción oportuna de medidas correctivas y, en algunos casos, la reparación financiera y la rendición de cuentas de los perpetradores, además de prevenir tales violaciones en el futuro. Sin embargo, si el control interno lo llevan a cabo los empleados, directamente subordinados al jefe de la organización controlada, no puede haber objetividad. En este sentido, los autores proponen utilizar la experiencia y las habilidades profesionales de los auditores independientes en la implementación del presupuesto de auditoría.State financial control (SFC) is an integral part of public administration. Its main goal is to identify deviations from standards, violations of the principles of legality, efficiency and resource saving as early as possible. This allows timely adoption of remedial measures, and, in some cases, financial reparation and accountability for perpetrators, as well as preventing such violations in the future. However, if the internal control is carried out by employees, directly subordinate to the head of controlled organization, there can be no question of objectivity. In this regard, the authors propose to use the experience and professional skills of independent auditors in auditing budget implementation.O controle financeiro estatal (SFC) é parte integrante da administração pública.

Solution of a dual integral equation arising in the contact problems of elasticity theory with the full Fourier series as the right-hand side

A class of dual integral equations is analyzed which arises in solution of a wide range of plane and antiplane contact problems of elasticity theory for a half-plane with functionally graded coating. In particular, a similar equation arises in solution of the contact problem on indentation in the presence of tangential stresses on a surface. The solution of the dual integral equation is sought in the form of a sum of even and odd functions. It makes possible to reduce the problem to independent solution of two dual integral equations over odd and even functions. Kernel transform of these equations is approximated by a product of fractional quadratic functions. The solution of dual integral equations is constructed in approximated analytical form by the bilateral asymptotic method. The expressions obtained are asymptotically exact for small and large values of a characteristic geometrical parameter
