Earth and Space Science, 2019 AbstractConcept of fractals and power law in statistical and geometrical data sets is rather matured. However, the application part of the fractal theory is not yet commensurate with the theoretical literature available. In this invited review, we take a dig at the range of data sets to demonstrate their fractal/scaling behavior for instance well logs ...

Geology prediction based on operation data of TBM: comparison between deep neural network and statistical learning methods [PDF]
2019 1st International Conference on Industrial Artificial
Intelligence (IAI), 2018 Tunnel boring machine (TBM) is a complex engineering system widely used for tunnel construction. In view of the complicated construction environments, it is necessary to predict geology conditions prior to excavation. In recent years, massive operation data of TBM has been recorded, and mining these data can provide important references and useful ...

On the Determination of the Solar Rotation Elements i, Ω and Period using Sunspot Observations by Ruđer Bošković in 1777 [PDF]
The Mining-Geology-Petroleum Engineering Bulletin, 2021, 36, 3,
pp. 77-98, 2022 In September 1777, Ru{\dj}er Bo\v{s}kovi\'c observed sunspots for six days. Based on these measurements, he used his own methods to calculate the elements of the solar rotation, the longitude of the node, the inclination of the solar equator and the period.

Snowball Earth climate dynamics and Cryogenian geology-geobiology
Science Advances, 2017 We review recent observations and models concerning the dynamics of Cryogenian global glaciation and their biological consequences. Geological evidence indicates that grounded ice sheets reached sea level at all latitudes during two long-lived Cryogenian
