In the gaseous phase, vibrational-, rotational- and translational-energy transfer between small molecules can be observed experimentally from time-dependent optical spectra. Populations in the ...

The term “system modeling” encompasses various techniques and methodologies which involve the coupling or uncoupling of models comprised of at least two components. Originally developed as a method of ...

Machine-vision and optical-inspection systems demand precise motion control, and this requires precision components. One often overlooked but important component is the zerobacklash coupling that ...

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

When an 8,000 MW coal plant upgraded its scrubbers, a coupling developed especially for use in wet flue gas desulfurization (FGD) systems was used for the nozzle-to-header pipe connections, instead of ...
