Surfaces From Deformation of Parameters
We construct surfaces from modified Korteweg-de Vries (mKdV) and sine-Gordon (SG) soliton solutions by the use of parametric deforma- tions. For each case there are two types of deformations. The first one gives surfaces on spheres and the second one gives highly complicated surfaces in three dimensional Euclidean space (R 3 ).

Buildings are vulnerable to collapse incidents. We adopt a workflow to detect unusual vertical surface motions before building collapses based on PS-InSAR time series analysis and spatiotemporal data mining techniques. Sentinel-1 ascending and descending

This study aimed to map and analyze the spatial pattern of the surface deformation associated with the 2024 Noto Peninsula earthquake (Mw7.5) using structure-from-motion/multi-view-stereo (SfM–MVS), an advanced photogrammetric technique. The analysis was

Deformations of weierstra� elliptic surfaces
Let \(f: X\to C\) be a Weierstraß elliptic surface, that is an elliptic surface with a section and with at most rational double points as singularities, whose fibers over the nonsingular curve C of genus \(g\) are all irreducible. The base field is algebraically closed and has characteristic different from two or three.

Data on Time-series Observation of Ground Subsidence in South Korea Using Sentinel-1 SAR Observations [PDF]
Ground subsidence is a phenomenon where surface materials sink due to a combination of natural and anthropogenic factors. South Korea has experienced human casualties and economic losses due to ground subsidence, such as sinkholes.

A Deformable Surface Model for Vascular Segmentation [PDF]
Inspired by the motion of a solid surface under liquid pressure, this paper proposes a novel deformable surface model to segment blood vessels in medical images. In the proposed model, the segmented region and the background region are respectively considered as liquid and an elastic solid.

Wrinkling of fluid deformable surfaces
Wrinkling instabilities of thin elastic sheets can be used to generate periodic structures over a wide range of length scales. Viscosity of the thin elastic sheet or its surrounding medium has been shown to be responsible for dynamic processes. We here consider wrinkling of fluid deformable surfaces.
