THREE DIMENSIONAL ATTRIBUTE MODELING AND DEEP MINERALIZATION

Twin screw air compressor modeling dimensions and specifications

Twin screw air compressor modeling dimensions and specifications

In this paper, an integral methodology for the modeling of a twin-screw compressor is presented. Starting from a known rotor profile, all the algorithms to calculate the second rotor profile, the size of the control volume, and the compressor's performance are presented. [pdf]

Deep foundation drill rigs

Deep foundation drill rigs

Drilled shafts are high-capacity deep foundation systems, also known as drilled piers, caissons, bored piles, or cast-in-drilled-hole piles (CIDH). Drilled shafts for structural support can be installed by the dry (open hole), stabilizing polymer slurry, or steel-cased methods. [pdf]
