When looking at power stones and crystal bracelets,8mm.10mm.12mm.There are items where the size of the beads differs even for ...

What is modal analysis? Evaluating vibration sensor enclosures and their natural frequencies. Determining the most important modes and frequencies with the mode participation factor. A close look at ...

Shearing a dusty plasma with a laser shows how vibrational modes lead to weak points in an amorphous active system. Drop a wine glass on a concrete floor, and it’s easy to predict what will happen.

Experiments disprove the general assumption that more than one wave mode is needed to produce a spectral pattern called a frequency comb. Frequency combs—sets of sharp, equally spaced spectral ...
