To protect environmental sustainability, organizations are moving their focus towards greening the business process. Similarly to any other business function, financial management has also turned to environmentally friendly activities. Green finance is a new financial pattern that integrates environmental protection and economic profits. This paper analyses the publications on green finance, and their intellectual structure and networking. The bibliometric data on green finance research have been extracted from the Scopus database. This study finds the most productive countries, universities, authors, journals, and most prolific publications in green finance, through examining the published works. Also, the study visualizes the intellectual network by mapping bibliographic coupling (BC) and co-citation. The study’s essential contribution is the analysis of green finance developments and trajectories that can help scholars and practitioners to appreciate the trend and future studies.
Based on 5G wireless communication technology, this paper proposes a secure online banking payment scheme using a password algorithm and identity authentication+SMS verification code. We use the lightweight block cipher algorithm to construct a numeric permutation table. Then, we use the digital permutation table to perform the permutation encryption operation to obtain the digital ciphertext data. Finally, we connect 5G radiofrequency identification, identity authentication, and other modules to the trusted computing platform. The research found that the online banking security encryption algorithm proposed in the paper has the characteristics of high security and high efficiency.
The paper starts with calculating the share of heat of condensate in thermal
power plants in the total heat of steam, expounds the purpose, significance,
and principle requirements of condensate recovery. Introduces the
composition and classification of condensate recovery system, proposes
technical and economic indicators for condensate recovery, and derives them
a simple algorithm for the benefit of condensate recovery is presented.
Finally, two calculation examples are used to illustrate the considerable
benefits of condensate recovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
