Recent Crustal Deformation in West-Central South America [PDF]

, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

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

Identifying Individual Rocks Within Laser Scans for a Rigorous Deformation Analysis of Water Dams [PDF]

, 2022
[EN] Water dams are an important infrastructure component for energy generation, water supply and flood control. Regular inspections of the structures for damage and deformation are necessary for safe operation and to ensure stability. In addition to the

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.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
