User privacy prevention model using supervised federated learning‐based block chain approach for internet of Medical Things

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract This research focuses on addressing the privacy issues in healthcare advancement monitoring with the rapid establishment of the decentralised communication system in the Internet of Medical Things (IoMT). An integrated blockchain homomorphic encryption standard with an in‐build supervised learning‐based smart contract is designed to improvise ...

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Underground Storage of Natural Gas

, 1989
The total global primary energy consumption for the year 1986 amounted to 322 000 PJ = 10 989 million tonnes HCE (hard coal equivalent). The percentage share of the various energy sources is shown in Fig. 1. Assuming a global population of 5 billion people this represents an average annual per capita consumption of about 2 t HCE.

Numerical investigation of natural fracture activation and leakage risk during CO2 sequestration in depleted sandstone reservoirs

Deep Underground Science and Engineering, EarlyView.
This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Analysis of lining force transmission coefficient and surrounding rock displacement in lined rock caverns for underground gas storage

Deep Underground Science and Engineering, EarlyView.
This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

Experimental study on the influence of shale content in fault zone on fault friction coefficient based on circular shear test

Ain Shams Engineering Journal
Water injection in fault block oil and gas reservoirs can trigger fault activity, leading to leakage and potential earthquakes, which may cause significant natural and economic losses.
