Research on Human Exposure to Transport-Induced Vibration in Buildings

Applied Sciences
The analysis of human perception of vibrations in buildings is a critical aspect of structural engineering, particularly as urbanization intensifies and the proximity of vibration sources to buildings increases.

Analysis and Numerical Simulation on the Reduction Effect of Stress Waves Caused by Water Jet Slotting Near Blasting Source

Shock and Vibration, 2016
As one of the most serious “side effects” of blast excavation, blast-induced vibration must be controlled for existing buildings and human beings. This paper proposes a method for blast-induced vibration reduction with water jet assistance according to ...

Assessment of vibration modulated regional cerebral blood flow with MRI

NeuroImage, 2023
Human brain experiences vibration of certain magnitude and frequency during various physical activities such as vehicle transportation and machine operation, which may cause traumatic brain injury or other brain diseases. However, the mechanisms of brain

Human-induced vibration of steel–concrete composite floors [PDF]

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2018
Long-span composite floors have many desirable properties and have been increasingly employed in building construction. However, these long-span structures are prone to excessive and complex vibration under human rhythmic activities such as walking, running, jumping and aerobics, which may result in people's discomfort and complaints. A finite-element

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Performance of Deltabeam–CLT Composite Floors Under Human-Induced Vibration

Buildings
In this study, the human-induced vibration performance of an innovative Deltabeam–CLT composite floor system was investigated. The Deltabeam–CLT composite floors were modelled using the finite element software package ABAQUS 6.14, the dynamic performance

Surface modification of 3D‐printed polycaprolactone scaffolds with silk fibroin for bone tissue engineering

FEBS Open Bio, EarlyView.
Coating 3D‐printed PCL scaffolds with silk fibroin can improve biocompatibility and bone cell adhesion. One innovative design for tissue‐engineering scaffolds uses 3D printing technology. Here, we used polycaprolactone (PCL) filament as a biocompatible material to design a porous 3D scaffold for bone tissue engineering.

An Estimation of Pedestrian Action on Footbridges Using Computer Vision Approaches

Frontiers in Built Environment, 2019
Vibration serviceability of footbridges is important in terms of fitness for purpose. Human-induced dynamic loading is the primary excitation of footbridges and has been researched with traditional sensors, such as inertial sensors and force plates ...

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design
