Multiple scales analysis confirms that, although the energy E, the angular frequency ω and the modal structure of the waves evolve, the wave action E/ω is conserved in the absence of forcing and ...

The LIDA 500 Series 20-µm incremental linear scale offers measuring steps of 1 to 0.1 µm.

In this paper, we investigate the various relationships among the linear programming solutions of data envelopment analysis (DEA) models under a constant returns to scale technology. We derive the ...

An upgrade to linear scales eliminated motion errors and improved the accuracy of a vertical machining center at Votaw Precision Technologies. Votaw Precision Technologies in Santa Fe Springs, Calif., ...
