Analysis of In Situ Optical Signals during Laser Metal Deposition of Aluminum Alloys

Crystals, 2021
During laser metal deposition (LMD) of thin-walled aluminum alloy structures, the deposition height and width is hard to keep stable because of the special properties of aluminum alloys, such as high reflectivity to laser beams, low viscosity, and high ...

Large Air-to-Water Heat Pumps for Fuel-Boiler Substitution in Non-Retrofitted Multi-Family Buildings—Energy Performance, CO₂ Savings, and Lessons Learned in Actual Conditions of Use

Energies, 2022
The use of air source heat pumps (ASHP) in the specific context of existing multi-family buildings (MFB) represents an important challenge, especially in terms of performance and technical constraints in real conditions of use.

A mini-microscope for in situ monitoring of cells [PDF]

Lab on a Chip, 2012
A mini-microscope was developed for in situ monitoring of cells by modifying off-the-shelf components of a commercial webcam. The mini-microscope consists of a CMOS imaging module, a small plastic lens and a white LED illumination source. The CMOS imaging module was connected to a laptop computer through a USB port for image acquisition and analysis ...

Shear-Induced Unfolding of Lysozyme Monitored In Situ [PDF]

Biophysical Journal, 2009
Conformational changes due to externally applied physiochemical parameters, including pH, temperature, solvent composition, and mechanical forces, have been extensively reported for numerous proteins. However, investigations on the effect of fluid shear flow on protein conformation remain inconclusive despite its importance not only in the research of ...

In-situ interferometric monitoring of optical coatings

Optics Express, 2020
We present a new method for the in situ measurement of the amplitude and phase of the reflection coefficient of a plane substrate installed in a mechanical holder rotating at high speed (120 turns per minute) during the deposition of optical thin films. Our method is based on digital holography and uses a self-referenced scheme to cancel the effects of

A Practical Structural Health Monitoring System for High-Speed Train Car-Body

IEEE Access, 2019
A practical structural health monitoring (SHM) system based on Lamb wave for high-speed train car-body structures is presented. The system can detect the occurrence and report the location and probabilistic size of structural damage in real-time.
