Optimal strategy for maximizing energy efficiency of 4G and 5G coexistence network by Yahui XUE, Zecai SHAO, Chunfeng CUI, Jing JIN, Hanning WANG

“…The energy efficiency of wireless networks has gradually become an important indicator for evaluating network performance.It’s very important to improve the energy efficiency of the coexisting 4G and 5G networks as there are differences in energy efficiency of them.Firstly, the energy consumption composition of base station was analyzed, energy consumption models for 4G and 5G base stations through measured data were established, and then its energy efficiency was evaluated through simulations.The results show that 4G and 5G have their own optimal energy-efficiency areas separated by the critical point of 500 Mbit/s, above which the 5G energy efficiency is better.When dual networks operate simultaneously under the proposed-solution where only 4G is used when the throughput is less than 500 Mbit/s and only 5G is used otherwise, the power consumption of a single station can be reduced by 53.4% and the energy efficiency can be improved by 116.4%.…”

Low-Cost Air Gap Metasurface Structure for High Absorption Efficiency Energy Harvesting by Wei Hu, Zhao Yang, Fading Zhao, Guangjun Wen, Jian Li, Yongjun Huang, Daniele Inserra, Zhizhang (David) Chen

“…Differently from the previously presented structures which require the use of thicker and low-loss (and for this reason high cost) dielectric substrates, the presented work employs a dual-layer structure with a thin low-loss material and an air gap; they allow for the design of very high absorption efficiency metamaterial-based surfaces, with noticeably reduced costs. …”

Impact of using metallized iron ore pellets to increase the efficiency of electric arc furnace by Ludmila N. Krakht, Edward E. Merker, Alexander Y. Kem, Victor A. Stepanov

“…It is found that the microstructure invariance of fluxed pellets including the bonded phase composition is determined by the level of fluxing and the difference of the iron valent states. Improvement in the efficiency of IMP melting is achieved by feeding pellets with improved physicochemical and technological properties, as well as supplementary materials, into the slag-metal bath through the axial passages of the electrodes.…”

Mechanism and spatial spillover effect of the digital economy on carbon emission efficiency in Chinese provinces by Yifen Xia, Yuanzhuo Wu, Yilin Qin, Chun Fu

“…Five findings are elicited: (1) Spatiotemporal distribution differences exist between digital economy level and carbon emission efficiency. (2) The digital economy effectively enhances carbon emission efficiency, a result that remains robust after endogenous and robustness tests. (3) Significant spatial spillover effects are observed, where improvements in the digital economy enhance carbon emission efficiency in neighboring areas. (4) The impact of the digital economy is more pronounced in eastern and high digital development regions but weaker in the northeastern and low digital development areas. (5) The main pathways through which the digital economy influences carbon emission efficiency are industrial structure upgrading, energy structure optimization, and green technological innovation. …”

EFFICIENCY OF ACID TREATMENT OF THE BOTTOM BOREHOLE ZONE OF THE WELL FOR SEDIMENTS WITH HARD-TO-REMOVE RESERVES by A. Kopytov, S. Levkovich, E. Levitina, I. Kovalev

“…The article discusses various methods of acidizing the bottomhole zone of wells operating deposits with hard-to-recover reserves The main criteria to be met by the acid composition used are given Results and Discussion The results of acid treatments in the wells of the Bazhenov and Tyumen deposits are presented For the Bazhenov deposits, in order to restore and improve the permeability of the bottomhole zone of formations composed of terrigenous reservoirs with high carbonate content, it is recommended to carry out acidizing at the stage of well development For the Tyumen deposits, the efficiency of treatment of the bottomhole zone of the well for individual fields differs significantly and depends on the treatment method and the concentration of reagents Conclusion For sediments of the Bazhenov formation at the Salym field, the success rate of operations is 20-30%, which is associated with the complex mineralogical composition of the rocks, and with low values of reservoir parameters, as well as temperature and pressure conditions of occurrence For the deposits of the Tyumen suite at the Lovinskoye field, the effectiveness of acid treatments varies from 30 to 100%, At the Russkinskoye field, the success of the measures is estimated at 95%.…”
