Natural frequencies are important dynamic characteristics of a structure where they are required for the forced vibration analysis and solution of resonant response. Therefore, the exact solution to ...
Reflected electron beams at quasi-perpendicular shocks generate a cascade of instabilities, contributing to their self-confinement and acceleration.
Long-established in accelerator physics, bent crystals are now being explored as tools to measure the fundamental properties of short-lived charm baryons. Halo extraction The first bent crystal of the ...
Enhancing the Accuracy and Range of Cantilever-Based Measurements in Optical Beam Deflection Systems
Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...
While working on validation examples for a material model, I encountered a behaviour I was not expecting. The setup involves a beam aligned with the x-axis that gets deflected in the y-direction due ...

Understanding the Deflection of Beams
In this video I take a look at five methods that can be used to predict how a beam will deform when loads are applied to it. These are the double integration method, Macaulay's method, the principle ...

'Planetary defense is knowing what's out there and what could do harm to us.' Meet the scientist who helped build NASA's asteroid response plan
A Q&A with Lindley Johnson, a pioneer in blueprinting warning and response scenarios to any potential impact of Earth by an ...
Abstract: Position measurement methods based on optical beam deflection (OBD) require sensing of the displacement of a cantilever's tip. When the cantilever is scanned over a surface, the tip is ...

NASA’s Double Asteroid Redirection Test mission struck the 160-m moonlet asteroid Dimorphos (shown) in September 2022, changing its orbital period but generating a trail of debris called a surface ...
These optical scanners comprise two separate, perpendicular planar mirrors that rotate independently. They are positioned in a manner wherein laser light bouncing off the first mirror (axis 1) ...
