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 ...

Customization of rotary and linear motion systems improves performance, reduces costs and simplifies complex applications in manufacturing and medical devices. Advances in smart, compact and ...

A rack and pinion steering system consists of a pinion (a circular gear) with a rack (a linear gear). The system works by converting a revolving motion into linear motion. Most cars, small trucks, and ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

The 2013 Linear Motion Catalog and Design Guide contains new product sections, including Idea encoder-ready stepper motor controllers, BGS linear rail systems, and a linear-rail application checklist.
