Tip-timing data analysis for mistuned bladed discs assemblies

, 2008
International audienceIn turbomachine industry, bladed assembly vibration measurements are very important for blades behaviour estimation. These measurements are generally obtained from strain gauges.

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs

Advanced Intelligent Discovery, EarlyView.
A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.

Identification of Asynchronous Blade Vibration Parameters by Linear Regression of Blade Tip Timing Data

, 2018
Fracture of blades is usually catastrophic and creates serious damages in the turbomachines. Blades are subjected to high centrifugal force, oscillating stresses, and high temperature which makes their life limited.

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Iteratively Learning Reconstruction of Blade Tip-Timing Signals and Cointegration-Based Damage Detection Under Variable Conditions

IEEE Access
Blade tip-timing (BTT) is a direct blade vibration monitoring technique and how to use under-sampled BTT signals for blade damage detection is still challenging under variable conditions. Compressed sensing (CS) has been introduced for reconstructing BTT

Influence of Fat Oil Binding Capacity on Shelf‐Life and Consumer Acceptance of a Chocolate‐Based Model System

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In chocolate‐coated products, oil migration can lead to chocolate softening and discoloration, filling hardening, and reduced consumer acceptance. This study examined three fats (soy‐, palm‐, and palm‐kernel (PK) based), crystallized under different conditions (cooling rate and high intensity ultrasound (HIU)) with differing oil binding ...

Vibrations measurements for shrouded blades of steam turbines based oneddy current sensors with high frequency response

Journal of Measurement Science and Instrumentation, 2019
With the development of power plants towards high power and intelligent operation direction, the vibrations or failures of blades, especially the last stage blades in steam turbines, happen more frequently due to the unstable operating conditions brought

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.
