This paper aims to examine the impact of information and telecommunication technologies (ICT-proxied by mobile phone subscription and Internet usage) on carbon dioxide (CO2) emissions in the Organization for Economic Cooperation and Development (OECD) countries from 1990 to 2018.

The Cross-section Autoregressive Distributed Lag (CS-ARDL) model is employed to address the potential cross-section dependence problem. Common Correlated Effects Mean Group (CCEMG) and Augmented Mean Group (AMG) estimators are used to test for robustness of results.

Results reveal contrasting effects of mobile phone subscription and Internet usage on CO2 emissions. While mobile phone penetration helps mitigate CO2 emissions, Internet usage tends to increase the emissions. Findings show that renewable energy is beneficial to the environment while economic growth is harmful to the environment. The effects of financial development and trade openness seem negligible.

This study offers practical implications for policymakers. As different proxies of ICT could have contradictory impact on CO2, governments should be cautious against utilizing ICT to mitigate CO2. Findings point to the benefits of renewable energy in alleviating CO2 emissions. Therefore, governments are strongly advised to implement policies facilitating renewable energy consumption.

Previous studies ignored the problem of cross-section dependence which could lead to biased results and cause misleading inferences. This study aims to fill this void in the literature.

In the traffic monitoring system, the detection of stirring vehicles is monitored by fitting static cameras in the traffic scenarios. Background subtraction a commonly used method detaches poignant objects in the foreground from the background. The method applies a Gaussian Mixture Model, which can effortlessly be contaminated through slow-moving or momentarily stopped vehicles.

This paper proposes the Enhanced Gaussian Mixture Model to overcome the addressed issue, efficiently detecting vehicles in complex traffic scenarios.

The model was evaluated with experiments conducted using real-world on-road travel videos. The evidence intimates that the proposed model excels with other approaches showing the accuracy of 0.9759 when compared with the existing Gaussian mixture model (GMM) model and avoids contamination of slow-moving or momentarily stopped vehicles.

The proposed method effectively combines, tracks and classifies the traffic vehicles, resolving the contamination problem that occurred by slow-moving or momentarily stopped vehicles.

To reveal the impact of the development of technology parks and innovative networks on the national digital economies.

The following methods are utilised: the complex method, statistical analysis, comparative method, correlation analysis and linear programming (method of the game approach category).

We reveal the impact of the development of technology parks and innovative networks on the national digital economies. Analysis of the formation of the digital economy includes the assessment of its components (Rank Knowledge, Rank Technology, Rank Future readiness) in the context of the development of the analysed developed countries (Belgium, France, Iceland, Spain and Hong Kong). It is discovered that Hong Kong and Iceland have high indicators of digital technologies implementation. We prove that these results are connected to investments in this sphere made by integration structures, including the sphere of business, sciences and government agents (in the case of Hong Kong). We perform an analysis of the clustering of the given countries and describe the main forms of integration that ensure the innovative development of the economy. Based on the study of analytical and statistical materials, we determine the perspective model of the impact of these integration mechanisms on the state of innovative development of the digital economy, which could be applied to developing countries.

The originality and value of this research are due to the development of a model of the impact of implementing the integration mechanisms on the state of innovative development of the digital economy, which could be used in the case of developing countries.

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming and powder metallurgy are briefly discussed. The range of applications of finite elements on the subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for the last five years, and more than 1100 references are listed.

Presents theoretical results regarding the computational estimation of the critical rotational speed in smooth or of negligible roughness and waviness hydrodynamically lubricated journal bearings. Results were provided using a developed calculational simulation code adapted to modelling of hydrodynamic lubrication regime encountered in the operation of various conventional or unconventional configuration finite journal bearings (j‐b). It is concluded that empirical formulae of general character used to determine j‐b rotational speed critical domain may either considerably underestimate or overestimate operational magnitudes. This fact leads to the necessity of use of high values for rotational speed safety factors in order to assure liquid lubrication and to avoid j‐b contacts during operation. Relevant diagrams resulting from the present investigation show a direct estimation of critical j‐b operational magnitudes.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The purpose of this research is to substantiate the processes of implementing the electronic forms of business integration under the conditions of digital transformation by market players.

The methods used in this research include cooperative game theory, systemic analysis and statistical analysis.

This research presents the substantiation of the processes of implementing the electronic forms of business integration under the conditions of digital transformation by market players. The proprietary methodology of evaluation of the set problems includes three procedures: analysis of the electronic forms of business integration that are used in the digital economy in the world, which envisages their systematisation; evaluation of the effectiveness of implementing the processes of business integration with the use of such forms and their forecast estimation under the condition of individual development of the market environment's players, as well as determination of advantages; and development of the practical implications for managing the electronic forms of business integration for the national companies of developing countries (with forecasting based on the cooperative game theory). The modern electronic forms of business integration include electronic cash (e-cash), electronic data interchange, electronic banking (e-banking), electronic marketing (e-marketing), electronic insurance (e-insurance) and electronic trade (e-trade). Analysis of the effectiveness of implementing the processes of business integration with the use of the electronic forms is performed based on electronic trade, which is used under the conditions of the functioning of digital trade platforms (Internet stores). Such digital trade platforms, as the forms of business strategies, are Amazon and eBay Inc. These two American companies were selected because the United States has the leading position in this sphere. The comparative analysis showed the advantages of participation of players in partnership with the use of electronic trade within two digital platforms, connected to cost saving on advertising and organisation of trade. The practical implications of implementing the electronic forms of business integration for the national companies of developing countries are also presented; they are formed based on the practice of implementing the advantages revealed in the activities of the digital trade platforms Amazon and eBay Inc.

The originality and value of this research are due to the further development of provisions on the specifics of the process of implementing the electronic forms of business integration under the conditions of digital transformation by market players.
