Introduction. The development of robotics in many advanced countries has raised various industries to a high level. The demand for robots increases the share of their use in production tasks, mainly in the motor-vehicle and electronics industries. Advanced robotics can increase productivity in many industries by 30%, while reducing labor costs. Automation of technological processes of electronics production has a positive impact on the use of robots. Robots are used in construction, logistics, oil and gas, aerospace, plant engineering and construction, mining, healthcare, etc. The authors consider robots from the point of view of their application in medicine for the rehabilitation of musculoskeletal patients. This paper describes the mechanisms for controlling the feet and the center of mass of a humanoid robot.Materials and Methods. The authors chose the simplest algorithm for searching for the law of motion control of a humanoid robot. The robot movement was presented as a reverse pendulum. Using the large kinematic redundancy of walking robots, we have developed a way to control the robot in such a way as to bring the dynamics of its movement to the reverse pendulum as close as possible. At the same time, the problem of determining the generalized coordinates is considered, at which a given position and orientation of the transferred foot and a given position of the projection of the center of mass (CM) of the robot onto the reference surface are provided.Results. The authors have developed a digitalized automatic control scheme for the movement of the feet and the center of mass of the human exoskeleton, which will largely reduce the load on a sick person.Discussion and Conclusions. When discussing the results, comparing the data of the tables obtained during the calculation, the following conclusion was made. The scheme for controlling the feet movement of a human exoskeleton developed by the authors is most effective when designing an automatic scheme for controlling the movement of the feet and the center of mass of a human exoskeleton using digital technology, which will largely reduce the load on a sick person.

The paper analyses methodological features and results of the first Russian oil and gas companies environmental rating. This rating is relevant because Russian oil and gas industry plays a key role in the national economy and at the same time it is unfavorable and nontransparent from an environmental point of view. Our study aims to provide a comparative assessment of environmental responsibility of oil and gas companies operating in Russia. The study is based on a comprehensive analysis of qualitative and quantitative corporate indicators in three areas: environmental management, environmental impact and disclosure. Results of the rating indicate a high differentiation among Russian oil and gas companies in terms of environmental responsibility and transparency. Public listing of shares as well as linkages between shareholders and regional communities are among factors that have positive impact on the level of environmental responsibility of oil and gas companies.

Ensuring the safety of oil and gas facilities and increasing their facility life are today one of the most important tasks. Emergencies related to rupture and damage of steel pipelines because of their wear and tear and external factors are still the most frequent cases of emergencies during the transportation of hydrocarbons. To expand the fuel and energy complex in the north, in the direction of the Arctic, alternative types of pipelines are needed that solve the problems of reducing energy and labor costs in oil and gas companies, reducing the risk of environmental disasters and depressurization of pipelines during hydrocarbon production. Fiber-reinforced thermoplastic pipes can be such an alternative. This article is devoted to a comparative analysis of the materials of a composite system consisting of a thermoplastic pipe (inner layer) and reinforcing fibers (outer layer); we are discussing the design of the structural system consisting of polyethylene (inner layer) and aramid fibers (outer reinforcing layer).

For more than half a century bicycle transport demonstrates its effectiveness as one of the elements of the transport network of the city. Currently, vehicles with low-power motors such as electric bicycle, electric scooter, gyrometer, segway, wheelbarrow, scooter motor and others are gaining people's attention. These vehicles can be combined into a group of low-speed individual vehicles (hereinafter - NITS) with similar re-quirements for the operational parameters of urban infrastructure. From the urban point of view, the interest in NITC is that the number of its users has increased significantly in recent years. The article presents the results of a sociological survey of residents of Serpukhov, allowing to assess the current and potential readi-ness of the population to use NITC. The growing popularity of NITC has led to an increase in the environmen-tal and economic effect, which is manifested at a particular level of development of the movement on NITC. The ecological and economic effect of the use of NITC has an extremely positive impact on the improvement of the urban environment. This article provides a list of indicators that reflect the growth in the standards of living of society from movement by the NITC, and the calculation of one of them - the increase in entrepre-neurial activity on the streets with increased traffic to the NITC. Indicators are necessary for calculation of complex criterion of efficiency and safety of street network due to development of the movement by NITC. The result will allow public authorities authorized to make decisions on the strategy of transport policy of cities to quantify the ratio of economic benefits from the development of infrastructure of the NITC with the cost of its construction and operation.

On January 4th 2007 TIGF published the following invitation for tenders: “Development and Provision of a Pipeline Integrity Management System”. The project was awarded to Bureau Veritas (BV), who proposed to meet the requirements of TIGF with the Threats and Mitigations module of the PiMSlider® suite extended with some customized components. The key features of the PiMSlider® suite are: • More than only IT: a real integrity philosophy, • A simple intuitive tool to store, display and update pipeline data, • Intelligent search utilities to locate specific information about the pipeline and its surrounding, • A scalable application, with a potentially unlimited number of users, • Supervision (during and after implementation) by experienced people from the oil and gas industry. This paper first introduces TIGF and the consortium BV – ATP. It explains in a few words the PIMS philosophy captured in the PiMSlider® suite and focuses on the added value of the pipeline Threats and Mitigations module. Using this module allows the integrity analyst to: • Prioritize pipeline segments for integrity surveillance purposes, • Determine most effective corrective actions, • Assess the benefits of corrective actions by means of what-if scenarios, • Produce a qualitative threats assessment for further use in the integrity management plan, • Optimize integrity aspects from a design, maintenance and operational point of view, • Investigate the influence of different design criteria for pipeline segments. To conclude, TIGF presents the benefits of the tool for their Integrity Management department and for planning inspection and for better knowledge of their gas transmission grid.

Integral Indicator

One of the main causes of accidents at hazardous production facilities of oil and gas production is the inefficient work of production control over compliance with industrial safety requirements. At present there are no criteria for its assessment in the Russian legislation. It is established in the study that that production control in the industrial safety management system performs the role of «control» in accordance with the Shewhart-Deming cycle PDCA, and its main function is to work with nonconformities. In connection with the above, it is proposed to approach production control not only from the point of view of the process, but also from the system approach. To assess the system functioning, the criteria of «effectiveness», «efficiency», «integral indicator» are considered. It is established that from the point of view of proactivity in achieving the goals of production control, the most preferable is the assessment of the integral indicator of the production control system functioning. The considered existing and possible approaches to the assessment of the production control system and the statistical processing of the results of the expert assessment of nineteen parameters confirmed the need for a systematic approach. Based on this, the hypothesis of the production control system functioning is proposed and statistically substantiated, and four main parameters for calculating the integral indicator of the production control system functioning are considered. The built mathematical model based on the fuzzy logic clearly demonstrates the dependence of the integral indicator of the production control system functioning on the considered input parameters. The proposed proactive approach to the assessment of the production control system through nonconformity management is universal and applicable to the «control» function of any control system. It can also be used in the work of Rostechnadzor and be an incentive for enterprises to improve the quality, efficiency, and effectiveness of the production control system.

Abstract As other companies registered in the US stock market, the company reports oil and gas reserves, in compliance with the definitions of the Securities and Exchange Commission (SEC). In addition, it complies internally with the guidelines established by the Petroleum Resources Management System to certify its resources. The PRMS focuses on supporting consistent evaluation of oil resources based on technically sound industry practices, providing fundamental principles for the assessment and classification of oil reserves and resources, but does not provide specific guidance for the classification and categorization of quantities associated with IOR projects. Recently, the company has implemented EOR pilot projects, and their results seem to show commerciality for future development or expansion to new areas, displaying multiple opportunities and proposals to incorporate reserves and resources. So far, the pilot projects and their expansions have been addressed only from the point of view of incremental projects, as an improvement over the previous secondary recovery. The company does not have sufficient track record in booking reserves or resources from EOR projects, their quantities have been incorporated following bibliographic references and results of EOR projects with proven commerciality around the world. For this reason, the need arose to have a tool that provides the company with methodological criteria to evaluate the resources and reserves inherent in this type of project, that incorporate the "best practices" of the industry and that respect the guidelines and definitions of PRMS for incremental projects. That was how, the need to meet this challenging goal led company to develop its "EOR Resources and Reserves Assessment Guide" with the advice of a renowned consulting company. Although the Guide is not intended to be a review of the large body of existing IOR literature, it contains several useful references that serve as a starting point for understanding the IOR project for assessment process of resources and reserves. This document shows the process of development and implementation of the EOR guide, complementing the existing guides within the corporation and providing the company with a positive result within the internal processes of Audit, reserves and resources for this type of projects.

The Impact

Purpose The purpose of this paper is to investigate how within-industry diversification affects the financial performance of small- and medium-sized enterprises (SMEs) in emerging markets (EMs). The authors draw on both the resource-based view and the institutional perspective and argue that within-industry diversification can enhance the financial performance of SMEs in EMs. Due to institutional voids in emerging economies, SMEs can gain additional benefits from scope economies, as well as from market returns, by filling product market voids and gaps in business ecosystems, while also enjoying low input and labor costs that reduce the coordination costs of diversification. This, in turn, enhances benefits of within-industry diversification, thereby resulting in higher financial profitability. Design/methodology/approach This study employs panel data econometrics to estimate the model. The authors test hypotheses on 195 firms, originating from five countries in Southeast Asia, during the period of 2009–2014. Findings The empirical results support the arguments. Within-industry diversification has a positive impact on the performance of SMEs in EMs. These effects become weaker when the institutional contexts are more developed. Nevertheless, such effects become stronger when SMEs in EMs are more efficient. Research limitations/implications The relationship between within-industry diversification and performance is a positive linear pattern, which differs from the pattern in advanced economies. In addition to unrelated diversification, the related diversification is preferable for firms in EMs. Practical implications The paper provides implications for SMEs that aim to enhance their performance by engaging in single product lines and within-industry diversification. Originality/value This paper examines the different ways within-industry diversification can enhance SMEs performance in EM contexts.

AbstractBackgroundIn 2006 the country of Georgia implemented Article 45 of the Administrative code and Article 273 of the Criminal Code of Georgia, a public policy that enable police to detain any individual, anywhere, at any time on grounds of suspicion of drug use; and require them to submit to urine screening to test for the presence of illegal drugs and their metabolites. This policy is referred to as the street drug testing policy. Positive drug screening results in fines and potential jail time. The purpose of this paper is to conduct a cost analysis of this policy and assess the execution of the policy and the extent to which the policy meets its stated aims.MethodsThis study employed cost analysis methodology to calculate annual direct material and labor costs associated with carrying out Georgia’s street level drug testing policy. These costs encompassed law enforcement, drug testing, associated judicial processes, imprisonment and income offset through fines collected during the two years covered in this study (2008 and 2014). In addition, we measured: fidelity of the execution of the policy measured by the accuracy of the percentage of people detained who were found to actually have used drugs; and the policy’s effectiveness in deterring drug use among those who tested positive. Impact on drug use behavior was measured through impact analysis interviews conducted with a national sample of 500 detainees who tested positive for drugs under Article 45 and Article 273.ResultsUsing conservative financial estimates the cost of carrying out the policy offset by fine revenues broke even in 2008 (−111,889 GEL); however, by 2014 the costs increased 20 % in conjunction with an 18 % increase in the number of people detained for testing. However, the percentage of people who tested positive for drugs declined 39 % indicating decreased fidelity in the execution of the policy; accompanied by a financial imbalance of −10,277,909 GEL. Moreover, effectiveness analysis revealed that within one month of being detained and having tested positive for drug use, over 90 % of individuals had returned to pre-detention drug use levels, and within 12 months 100 % of detainees had resumed prior drug use behaviors.ConclusionThe financial costs associated with Georgia’s street level drug screening policy has rapidly increased while becoming decreasingly accurate and efficient in its execution. Moreover, data indicates that the policy is not effective in reducing or stopping drug use among those who tested positive. In conclusion, it is fiscally unsustainable to continue the policy as it is being executed and the policy is ineffective in changing drug use behavior among people who use illegal substances.
