The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...

The study of stochastic differential equations (SDEs) has long been a cornerstone in the modelling of complex systems affected by randomness. In recent years, the extension to G-Brownian motion has ...

A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

Linear motors have earned a reputation as highly precise and efficient alternatives to conventional rotary-to-linear transmission systems. Find out why, plus learn about the ultra-precise and ...

There are nuances to particle movement and energy at tiny scales that one of Einstein's equations did not capture, according to a paper published in Science this week. Researchers were able to measure ...

Macromolecular diffusion in homogeneous fluid at length scales greater than the size of the molecule is regarded as a random process. The mean-squared displacement (MSD) of molecules in this regime ...
