Identification of Ground Deformation Patterns in Coal Mining Areas via Rapid Topographical Analysis

Land, 2023
Coal mining inevitably brings some negative impacts, such as surface subsidence, aquifer breakage, and land degradation, to the eco-geological environment in the mining area. Among these impacts, coal mining-induced ground deformation is the most serious

Numerical Renormalization Approach to Two-Dimensional Quantum Antiferromagnets with Valence-Bond-Solid Type Ground State [PDF]

, 1999
We study the ground-state properties of the two-dimensional quantum spin systems having the valence-bond-solid (VBS) type ground states. The ``product-of-tensors'' form of the ground-state wavefunction of the system is utilized to associate it with an ...

Ground-Based Deformation Monitoring

, 2014
The observation and analysis of movements of large structures, man-made as well as natural ones, such as high-rise buildings, dams or rock slides and earthquake zones, is a highly responsible task in engineering. Deformation monitoring is essential to public safety by reducing the risk of structural failure.

Deformation information system for facilitating studies of mining ground deformations – development and applications [PDF]

Natural Hazards and Earth System Sciences, 2013
Abstract. The paper presents the concept of the Deformation Information System (DIS) to support and facilitate studies of mining ground deformations. The proposed modular structure of the system includes data collection and data visualisation components, as well as spatial data mining, modelling and classification modules.

Evaluating a Pragmatic Strength Alternative for Frailty Measurement and Assessing Its Predictive Capacity Against Established Frailty Instruments in Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Objective Frailty occurs prematurely in rheumatoid arthritis (RA) and is associated with poor health outcomes. We compared the performance of four frailty instruments, including a pragmatic alternative measure using chair sit‐to‐stand (STS), and evaluated their abilities to predict poor health outcomes.

Characteristics of deformation and defect of shield tunnel in coastal structured soil in China

Underground Space
Shield tunnel is a type of linear underground structure assembled by lining segments, characterized with long joint, weak stiffness, and strict deformation control requirement. The situation of the long-term deformation and defect of the shield tunnel in

Decoherence induced deformation of the ground state in adiabatic quantum computation

, 2013
Despite more than a decade of research on adiabatic quantum computation (AQC), its decoherence properties are still poorly understood. Many theoretical works have suggested that AQC is more robust against decoherence, but a quantitative relation between ...

Wheel rolling on deformable ground with slippage

IOP Conference Series: Materials Science and Engineering, 2021
Abstract A characteristic feature of wheeled earth-moving machines and tractors is their operation on deformable soils. This makes it necessary to consider the features of the interaction of elastic wheels with the ground, including such issues as the depth of the track and power losses for rutting, wheel movement along the laid track ...
