Ensuring Operational Reliability of Overpass on "Almaty-Kapshagai" Highway Section in Kazakhstan

The article presents results of the overpass condition survey, technical survey, static tests and assessment of the structure operational reliability, a doubledecker overpass on Almaty-Kapshagai highway section in Kazakhstan. Technical survey determined the dimensions of the overpass, the camber of reinforced concrete superstructures main beams and checked the values of the overpass roadway actual transverse and longitudinal slopes. The calculation and analytical assessment of the overpass load-bearing structures, for the strength of the bending moment, are performed. Static tests of the overpass split beam superstructure of a length of 33.0m were conducted. Trucks loaded with ballast were accepted as a test load.

Analytical assessment of sunflower production in ukraine

The article considers the current state of sunflower production in Ukraine. The main indicators of the industry, the dynamics of changes in the area of sunflower crops, yield and profitability are analyzed. The main factors influencing the production of sunflower using index analysis have been studied. The regional structure of sunflower production is considered with the separation of groups of enterprises by organizational form. Ukrainian enterprises are provided with proposals to increase the level of industry development and production.

Economic Availability of Forest Resources in Russia: An Analytical Assessment

The topic of the availability of forest resources is especially relevant for Russia, given the volume of the existing potential of these resources, distributed over a huge area of the country. The purpose of the article is to substantiate the possibilities of using the economic availability of forest resources in the practice of forestry in the Russian Federation. The article presents an analysis of the application of tools based on the economic availability of forest resources. It presents the classification of the forms of forest resources availability and analysis of possible situations that may occur assessing the economic availability of forest resources. The authors analyzed various methods of assessing the economic availability of forest wood resources, formed a criterion of economic availability and considered various conditions of economic availability. The results of calculations of economic availability assessments for the Vilegodskoe forestry located in the southeastern part of the Arkhangelsk region, according to which 19.1% of the analyzed plots were recognized as economically unavailable, are presented. The analysis of the characteristics of economically unavailable forest wood resources in the studied object has been carried out. Proposals have been developed on the spheres of the possible use of the toolkit for the economic availability of forest wood resources. The economic availability of forest resources can be widely used in the forestry practice of the Russian Federation in the areas of pricing and forest exploitation optimization. Its application will increase the level of payments for forest resources, due to the withdrawal of excess profits of loggers, and will also ensure the formation of more realistic forest plans.

Integrated Pedal System for Data Driven Rehabilitation

We present a system capable of providing visual feedback for ergometer training, allowing detailed analysis and gamification. The presented solution can easily upgrade any existing ergometer device. The system consists of a set of pedals with embedded sensors, readout electronics and wireless communication modules and a tablet device for interaction with the users, which can be mounted on any ergometer, transforming it into a full analytical assessment tool with interactive training capabilities. The methods to capture the forces and moments applied to the pedal, as well as the pedal’s angular position, were validated using reference sensors and high-speed video capture systems. The mean-absolute error (MAE) for load is found to be 18.82 N, 25.35 N, 0.153 Nm for Fx, Fz and Mx respectively and the MAE for the pedal angle is 13.2°. A fully gamified experience of ergometer training has been demonstrated with the presented system to enhance the rehabilitation experience with audio visual feedback, based on measured cycling parameters.
