CONCRETE DEFORMATION MODEL FOR RECONSTRUCTED REINFORCED CONCRETE

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2022
During the reconstruction, or upon expiration of the service life, as well as after external impact, reinforced concrete structures require examination and verification calculations. Existing diagrams of concrete deformation are focused on designing new

Two-Step Calibration Method for Inverse Finite Element with Small Sample Features

open access: yesSensors, 2020
When the inverse finite element method (inverse FEM) is used to reconstruct the deformation field of a multi-element structure with strain measurements, strain measurement errors can lower the reconstruction accuracy of the deformation field. Furthermore,

Reflection of Multiple Loading in The Deformation Model for Reconstructed Reinforced Concrete

open access: yesЖелезобетонные конструкции, 2023
During the reconstruction, or upon expiration of the service life, as well as after external impact, reinforced concrete structures require examination and verification calculations.

Automatic 3D facial model and texture reconstruction from range scans [PDF]

open access: yes, 2010
This paper presents a fully automatic approach to fitting a generic facial model to detailed range scans of human faces to reconstruct 3D facial models and textures with no manual intervention (such as specifying landmarks).

Detection of Pipeline Deformation Induced by Frost Heave Using OFDR Technology

open access: yesFrontiers in Physics, 2021
Oil and gas pipelines are critical structures. For pipelines in the seasonal frozen soil area, frost heave of the ground will result in deformation of the pipeline. If the deformation continually increases, it will seriously threaten the pipeline safety.

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

open access: yes, 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,

Three-Dimensional Curve Reconstruction Based on Material Frame and Twisted Multicore Fiber

open access: yesIEEE Photonics Journal, 2022
We propose a curve reconstruction model based on material frame and twisted multicore fiber (MCF), which can reconstruct the position and orientation of MCF simultaneously.

Deformable Ultrasound Registration without Reconstruction [PDF]

open access: yes, 2008
Ultrasound (US) imaging is often proposed as an interoperative imaging modality. This use nearly always requires that the collected data be registered to preoperative data of another modality. Existing intensity-based registration approaches all begin by reconstructing a 3D US volume from the collected 2D slices. We propose to directly register the set
