material, such as appliances and lengths of steel cable. Soil Separation (Screening) A trommel (i.e., a revolving cylindrical sieve) or vibrating screens separate soil (including the cover material) from solid waste in the excavated material. The size and type of screen used depends on the end use of the recovered material.

In other cases, the objective is to control, maximize, or optimize system vibrations (e.g., atomic force microscopes or vibrating screens used in raw material processing or drilling operations). Testing Services: Shock and vibration testing; Design of experiments (DOE) and selection of appropriate sensing technologies
