Scientists engineered a nanostring that cascades energy through five vibration modes from a single push, opening new paths for ultrasensitive nanoscale sensors. (Nanowerk News) Scientists at TU Delft ...

A new control approach based on fuzzy sliding mode control (FSMC) is proposed to regulate the chaotic vibration of an axial string. Hamilton’s principle is used to formulate the nonlinear equation of ...

In this example we considered the free response of a fixed-fixed string to a set of initial conditions that resulted from pulling the string at its midpoint and releasing it from rest. We found that ...
