A Comprehensive Review of Transformer Winding Diagnostics: Integrating Frequency Response Analysis with Machine Learning Approaches

Energies
Frequency Response Analysis (FRA) is a proven method for detecting mechanical faults in transformers, such as winding deformations and short circuits. However, traditional FRA interpretation relies heavily on visual and subjective comparison of frequency

Determination of HSS Model Parameters for Soft Clays in Hangzhou: Statistical Analysis and Engineering Validation

Buildings
The hardening soil model with small-strain stiffness (HSS model), capturing nonlinear stiffness of soils at small strains, offers advantages for deformation analysis of tunnels or deep excavations in soft clay areas such as Hangzhou City.

Laser Scanner–Based Deformation Analysis Using Approximating B-Spline Surfaces

Remote Sensing, 2021
Due to the increased use of areal measurement techniques, such as laser scanning in geodetic monitoring tasks, areal analysis strategies have considerably gained in importance over the last decade. Although a variety of approaches that quasi-continuously

VIBRATION ANALYSIS AND DEFORMATION MEASUREMENT [PDF]

, 1978
It appears that speckle techniques for deformation measurement and vibration analysis will be developed further. The results obtained are generally easy to interpret, compared with those from holographic interferometry, and the mathematics involved is not difficult.

Understanding creep in sandstone reservoirs – theoretical deformation mechanism maps for pressure solution in granular materials [PDF]

, 2014
Subsurface exploitation of the Earth’s natural resources removes the natural system from its chemical and physical equilibrium. As such, groundwater extraction and hydrocarbon production from subsurface reservoirs frequently causes surface subsidence and

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A Monitoring Method Integrating Terrestrial Laser Scanning and Unmanned Aerial Vehicles for Different Landslide Deformation Patterns

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The three-dimensional deformation monitoring of landslides is very complex due to the uncertainty of movement direction and the difficulty in searching the corresponding points before and after deformation.
