Gradient boosting to boost the efficiency of hydraulic fracturing [PDF]
Journal of Petroleum Exploration and Production Technology, 2019 In this paper, we present a data-driven model for forecasting the production increase after hydraulic fracturing (HF). We use data from fracturing jobs performed at one of the Siberian oilfields. The data includes features, characterizing the jobs, and geological information.

Interleaved, Switched Inductor and High-Gain Wide Bandgap Based Boost Converter Proposal
Energies, 2021 Many applications (electric vehicles, renewable energies, low-voltage DC grids) require simple, high-power density and low-current ripple-boost converters. Traditional step-up converters are limited when large transformation ratios are involved.
