In this paper, we address the challenges of applying three-dimensional virtual worlds for learning. Despite the numerous positive conclusions, this technology is far from becoming mainstream in education. The most common problems with applying it in everyday teaching and learning are steep learning curve and demand for computational and network resources. In order to address these problems, we developed a stream processors texture generation model for displaying educational content in 3D virtual worlds. The model suggests conducting image-processing tasks on stream processors in order to reduce the load on CPU. It allows designing convenient and sophisticated tools for collaborative work with graphics inside a 3D environment. Such tools simplify the use of a 3D virtual environment, and therefore, improve the negative learning curve effect. We present the methods of generating images based on the suggested model, the design and implementation of a set of tools for collaborative work with 2D graphical content in vAcademia virtual world. In addition, we provide the evaluation of the suggested model based on a series of tests which we applied to the whole system and specific algorithms. We also present the initial result of user evaluation. © 2013 IEEE.

In this paper, we suggest a method for collaborative work with large amount of graphical content in 3D virtual worlds. We argue that applying this method will benefit educational and other professional use of this technology. The most common problems with applying 3D virtual worlds in everyday teaching and learning are steep learning curve and demand for computational and networking resources. The suggested method allows reducing the load on CPU, and therefore, designing convenient and sophisticated tools for collaborative work with graphics inside a 3D environment. We present the methods of generating images, the design, and implementation of tools we developed for vAcademia virtual world based on this method. We discuss the educational value of the possibilities to work with large amount of graphical content in a 3D virtual world, which were limited before. We provide performance evaluation of the suggested method based on a series of tests which we applied to the whole system and specific algorithms. In addition, we present the initial result of user evaluation. © 2013 IEEE.

The author proposes the «neuron-synapse model of institutional environment» of natural resource-based multi cluster as a development of methods for design institutional environment of industrial clusters. This model allows to expand the methodological approaches to the identification of multi cluster formations at the regional level. The proposed algorithm for development a comprehensive economic-mathematical model of clustering processes allow to monitor the effectiveness of the regional cluster policy in the long term. The study shows methodological advantages of combination of micro and macro approach to research natural resource-based multi clusters due to a two-component composition of the multi cluster «core».

The article offers the technique of choice of rational variants of placing the main skid roads in the forest compartment. This technique allows to reduce the cost of construction of loading points, skid roads and skidding of timber. The method is characterized by complex analysis of the process of logging from multiple disparate cutting areas within boundaries of the forest compartment with existing network of forest roads. The algorithmic graph theory is used in the calculations for solving this problem. The proposed method is recommended for low-volume logging companies who rent plots in limited operational forest areas.

During operation of hydrosystems, a number of environmental problems, associated with the water-race conjugation by the transition from a protected part of the apron to the loose erodible bed, appears. By significant flow velocities, an erosion pool develops which can lead to loss of the hydrosystem stability. For the environmental protection of the tailrace facilities by the operation of hydrosystems, devices characterized by deployment and installation mobility are required. Effective hydrodynamic controllers of the near-bottom flow rate can be developed based on the theory of a profile, flowed round by fluid. The constructive design of such devices may be fulfilled based on the profiles made of flexible materials. To determine the parameters of the flexible profiles, it is necessary to determine experimentally the regularities of the flow distribution in the tailrace in different operating modes of gates and its influence on the depth of erosion. Experimental research of the tailrace bed erosion was performed on a scale model of the overflow weir of Cheboksary hydropower station in the hydraulic flume. For the open flows having non-deformable bed, a basic criterion of dynamic similarity is the Froude number. Work of the stream, by erosion of the bed formed with viscoplastic soil, was investigated on the basis of the dimensional theory. The regression dependence of the model diameter on the value of the soil adhesion was obtained. To measure the flow velocity in the model flume, a measuring system was developed based on heat-loss anemometers with an analog-digital converter and computer data logging. During the homing experiment we tested representativeness, accuracy, reliability, uniformity, variability, distribution of the recorded data. Check of the reproducibility of the experiment results was carried out by the Cochran criterion. Adequacy of the received data was evaluated by Fisher’s fitting criterion. Comparison of experimental measurements of kinematic characteristics obtained on a laboratory model, with actual values, showed good convergence. The nature of erosion in different operating modes of gates was studied. On the basis of measurements, we constructed lines of equal depths and isotachs for each flow rate and set the maximum depth of erosion. The model device for controlling the bed erosion in the hydrosystem tailraces based on the down-dropped airfoil was tested. The tested airfoils were installed in the hydraulic flume in the place of the flow descent from the model weir apron. The test of the model device was carried out with the most unfavourable operation mode for gates in relation to erosion and extreme water flow. A reduction of the maximum depth of the erosion pool during work of the airfoil was established. © SGEM2014..

A new hole-filling method for morphological image reconstruction is proposed in this article. The approach is based on a combination of methods of contour analysis and morphological image processing. For the hole parameters to be estimated, they are described analytically as contours. Then, parameters of the contours, namely the area or the length, are estimated, followed by the decision as to the filling of the contour-bounded hole. © 2015, Computer Optics. All Rights Reserved.

Purpose: This study aims to investigate the prospects for cluster modeling of ethno-tourism development in Russian regions. Design/methodology/approach: This study uses the methods of system and comparative analysis, mathematical statistics, managerial diagnostics, expert estimates, in-depth interview, cluster method and social and psychological testing. Findings: A significant number of Russian and international researchers study the problem of cluster and network interaction in economics using different perspectives. Special attention should be paid to the theory of cluster and network interaction in the field of tourism. This theory establishes the framework for the formulation of the concept of regional tourism development. The author believes that the concept should be developed using network forms of interaction in the field. Practical implications: The government should support cluster initiatives to improve the competitiveness of the country in the field of tourism. Further, this cluster policy should include tourist centers with the best prospects, as they are capable of stimulating the country’s economy, and develop a legal framework to provide cluster initiatives support. Otherwise, cluster and network modeling is likely to fail. Another limitation is the negative attitude of local and conventional religious communities toward the ideas of ethno-tourism issues; the best example is the included case study from Mari El Republic, Russia. Originality/value: Given the wide ethic, cultural and geographical differences within the Russian Federation, it is helpful to develop a spatial model of cluster and network organization for tourism based on selection of the areas that feature unique natural and recreational potential in addition to historical and cultural attractiveness. These areas can be viewed as places where various cluster tourist initiatives and local tourist clusters can be implemented. The use of ethno-tourism as a base concept for local tourism development in the region is bound to make the region more attractive for investors and, thus, support and promote interest in the unique culture of the indigenous peoples. © 2016, © Emerald Group Publishing Limited.

The aim of this work is to determine the capacity of forest areas, suburban and urban parks. Evaluation of the maximum allowable recreational pressure in the places of mass recreation from the negative influence of the anthropogenic factor taking into account the digression was found. In this regard, the results of our study indicate the necessity of applying for calculating attendance and recreational load on the territory of the Volga Federal district of Russia “all-Union standards for forest inventory”.. For calculations, you should use the developed indicators maximum allowable recreational pressure on 1 ha of forest land. Which in different forest conditions and in a certain sequence allows to calculate the maximum number of visitors. That is used for settlements for the places of mass rest, as districts, and individual parts of recreation objects or objects in General, without violating the environmental balance. For example, forests operational purposes, i.e., the fourth class of recreational suitability. In the end, was developed a unified approach to the definition of non-recurring and extreme loads on forest objects of mass recreation that allows you to set the number of visitors type of forest recreation. The proposed method of analysis allows to determine the stage of recreational digression and to provide more detailed information about recreational load. In all cases, after the higher stages of digression data will be the basis for assigning measures to protect the environment. To exclude the presence of degraded areas, apply the calculated coefficients по stages digression OST 56-100-95. and data researchers. The calculated allowable recreational load will more accurately determine the attendance of urban forests and parks, taking into account the category of recreational forests. Can be planned in the organization of recreational monitoring. Will be undertaken certain measures on the protection of forests. © SGEM2015.

Conjugation of the hydrosystem tailraces leads to the formation of a jet stream, causing scour of the unprotected part of the tailrace behind the end apron structures. In the tailrace, a plunge basin is formed, the parameters of which depend on cohesion of the foundation soil. Prediction of local scours shall be carried out depending on the soil cohesion, with a glance to the hydraulic size of particles making up the tailrace foundation. © SGEM2015. All rights reserved.

When determining the stages of evaluation of forests for recreational purposes and the presentation of the measurement results from exposure to recreational use, developed a phased differential principle. He includes the use of common indicators and industry standards. All proposed stages allow us to determine the stage of recreational digression and to provide additional information about the state of forest landscapes. In all cases, the third and higher stages of digression load will be the basis for assignment of forestry and environmental activities. Developed methodologically - consistent approach to the definition of non-recurring and extreme loads on forest objects mass leisure enables to set the number of visitors by type of forest recreation. The results of the research are as follows: - clarified the permissible recreational pressure in the zone of southern taiga and mixed coniferous-deciduous forests will more accurately determine the operating conditions of forest recreation; - stages identify the stages of recreational digression is characterized by flexibility, which will allow you to organize the monitoring of natural forest complexes for specific forest conditions; - based on the developed model, the proposed factors for the regulation of recreational pressure on forest areas with a critical number of visitors will help to solve the question of where to apply a more timely response to the impact of recreational purpose and carrying out forestry work. © SGEM2015.
