The article analyzes the aspects of the development of innovation engineering as a tool for maximizing the profit of an enterprise, including through the implementation of diversification measures (the use of various types of engineering in the design of innovative solutions). The feasibility of developing engineering services as an optimal solution to minimize losses from the COVID-19 pandemic has been determined. An overview of key indicators of Russian engineering is presented, the characteristic specifics of the integration of innovations in the project format in the context of engineering are substantiated. Aspects of engineering activities lie in the field of innovative characteristics of the project, in this connection, it is logical to consider engineering as "engineering innovations" - as a set of works performed and / or services provided within the framework of the formation of a project, of an innovative nature (including creation, execution, promotion of a project regarding the object of innovation). The article schematically presents the structural elements of the complex of works performed (services provided). Innovative design as a product of innovation engineering appears to be a significant tool in achieving high production rates and increasing the economic performance of a business entity. Given the nature of the negative impact of the COVID 19 pandemic on the economic environment in all sectors of the economy, innovative design, as meeting the need for innovative solutions (within the framework of engineering as a format for implementation), is seen as a promising option to increase production growth rates.

Abstract This study examines the role of financial inclusion on the environment-economic performance in the top five Asian emerging economies. The data used for empirical investigation covers the time period from 1995 to 2019. Financial inclusion is measured through bank branches, bank credit, and insurance premiums. To check long-run associations, the panel-ARDL approach has been employed for empirical analysis. The empirical evidence confirms the significant associations between financial inclusion-GDP nexus and financial inclusion-CO2 nexus. The findings show that bank branches and bank credit have a significantly positive impact on economic growth and CO2 emissions in the long-run. However, insurance premium has no impact on economic growth but it exerts a significant negative impact on carbon emissions in the long-run. Furthermore, energy consumption is highly sensitive to economic growth and carbon emissions. The study delivers imperative points for pollution eradication and attaining sustained economic growth. There is a need for government-level efforts to align the targets of financial inclusion with economic growth and environmental policies.

The extraction of china clay in the South West of the UK generates waste in a mass ratio of 1:9 for china clay: waste. Currently, part of the coarser waste, “stent” and sand named “china clay sand” (CCS) in this study, is used as building stone or secondary aggregate in concrete and asphalt but the finest waste fraction, called “mica” waste, is used only for the restoration of old quarries. Looking for innovative solutions for the needs of a new Eco-town in the UK, and with regard to uses commercially applicable to construction and of low environmental impact, the china clay waste is being studied as an aggregate in alkali-activated cements (AAC). Aiming to replace primary aggregates with wastes in low risk construction materials, a series of AAC concrete based on a 50% GGBS and 50% fly ash (FA) blend and an equivalent Portland concrete series were produced. In the mixes the primary aggregate was steadily replaced by forms of the waste and tests in compression showed a decreasing trend in strength accordingly. The two series of concrete follow approximately the same ratios of decrease although in absolute values the AAC series reached higher range of strengths on the 28 day compared to the Portland series. While the use of CCS did not have any negative impact, the addition of mica decreased the strength up to 25% more.

Purpose Corporate environmental expenditure has been a growing concern in recent years, yet mixed findings exist regarding its economic impact. The purpose of this paper is to explain the mixed relationship between environmental expenditure and economic performance from the natural-resource-based view. Design/methodology/approach Using Global Reporting Initiative survey data from 120 firms in 30 countries, this study uses PROCESS, a path-based analysis software, to test the moderation and mediation hypotheses in an integrated analytical model. Findings The findings show that environmental expenditure has a negative impact on economic performance through pollution prevention capability. In contrast, environmental expenditure has a positive impact on economic performance through product stewardship capability. Both effects are significantly strengthened when the firm is located in an environmentally munificent country. Practical implications This study intends to inform firm managers, especially those in environmentally munificent countries, to relocate their environmental expenditure to enhance firms’ economic performance. In particular, firms should focus more on the reduction of input, such as raw materials, energy, and water, instead of output, including emissions, effluents, and wastes. Originality/value The contrasting indirect effects of pollution prevention and product stewardship offer a viable explanation for the mixed findings in the existent literature on environmental expenditure from a new perspective.

The BP West Sole gas field is located in Block 48/6 in the UK sector of the southern North Sea, about 70 km off the Holderness coast. Production from the gas field is exported to a shore terminal at Easington by two pipelines. Both pipelines were trenched at installation. Pipeline surveys over the last few years show that both pipelines are substantially exposed at the shore approach and inshore sections. This has occurred in part due to the retreat of the cliffs in Easington and subsequent lowering of the sea bed level and also the migration of sand from around the pipelines leaving them largely unburied and sitting on the local clay abrasion platform. It has been concluded that both pipelines require stabilisation sooner rather than later to reduce the risk of pipeline failure. Pipeline stabilisation options need to take account of the environment in which they have been placed. Easington is at a critical position along the Holderness coast. All net sediment transport from the Holderness coastline passes through this section. Any interruption to this movement could result in a change to the adjacent coast. Maintenance of the sediment budget is important to a wider area of the East coast of England. Stabilisation options must not reduce the net amount of sediment moving southwards past Dimlington and must not result in any long term negative impact on the coastal evolution. This paper outlines consultancy required and problems process regarding the geomorphological issues in getting acceptance from government and non-government bodies. A methodology has been developed that allows quantification of impacts of different options on the sediment budget and on the long-term coastal evolution (see also Chen et al 1998, 2001 and 2002). Application of this method aimed at providing understanding and information which is considered to be important in the process of selecting an optimal solution for the pipeline stabilisation in such an environmental sensitive coast.

Iteration Algorithm

This paper considers satellite communication networks where each satellite terminal is equipped with energy harvesting (EH) devices to supply energy continuously, and randomly transmits bursty packets to a geostationary satellite over a shared wireless channel. Packet replicas combined with a successive iteration cancellation scheme can reduce the negative impact of packet collisions but consume more energy. Hence, appropriate energy management policies are required to mitigate the adverse effect of energy outages. Although centralized access schemes can provide better performance on the networks’ throughput, they expend extra signallings to allocate the resources, which leads to non-negligible communication latencies, especially for the satellite communication networks. In order to reduce the communication overhead and delay, a distributed random access (RA) scheme considering the energy constraints is studied. Each EH satellite terminal (EH-ST) decides whether to transmit the packet and how many replicas are transmitted according to its local energy and EH rates to maximize the average long-term network throughput. Owing to the nonconvexity of this problem, we adopted a game theoretic method to approximate the optimal solution. By forcing all the EH-STs to employ the same policy, we characterized and proved the existence and uniqueness of the symmetric Nash equilibrium (NE) of the game. Moreover, an efficient algorithm is proposed to calculate the symmetric NE by combining a policy iteration algorithm and the bisection method. The performance of the proposed RA scheme was investigated via numerous simulations. Simulation results showed that the proposed RA scheme is applicable to the EH devices in the future low-cost interactive satellite communication system.

Damping Treatments

The chief tool for design of viscoelastic-based damping treatments over the past 20 years has been the modal strain energy (MSE) approach. This approach to damping design traditionally has involved a practitioner to vary placement and stiffness of add-on elements using experience and trial and error so as to maximize the add-on element share of system MSE in modes of interest. In this paper we develop a new technique for maximizing strain energy as a function of stiffness for add-on structural elements modeled as rank r perturbations to the original stiffness matrix. The technique is based on a constrained substructure approach allowing us to parameterize strain energy in terms of the eigenvalues of the perturbed structure. An optimality condition is derived that relates the input-output response at the attachment location of the add-on elements to the maximum achievable strain energy. A realizability condition is also derived which indicates whether or not the optimal solution is achievable with passive structural elements. This method has applications in the design of structural treatments for controlling sound and vibration and promises an efficient means of determining the limits of performance of passive structural treatments. An advantage of our approach over existing methods is that the maximum achievable strain energy fraction in the add-on elements is directly computable with the realizability condition then indicating whether the optimal solution is achievable.
