Class III / short line system inventory to determine 286,000 lb (129,844 kg) railcar operational status in Kansas and determination of ballast fouling using ground penetrating radar
… of measuring ballast fouling nondestructively. A 48 x 48 x 48 in (1.2 x 1.2 x 1.2 m) test box was built. The test box was filled with 48 in (1.2 m) of clean and ballast. Tests were run on dry and partially saturated material, wetted using 6 gallons (22.7 L). GPR data were collected hourly for the …

Design, Fabrication, and Experimental Investigation of an Additively Manufactured Flat Plate Heat Pipe
… fabricate a fully operational compact (78 mm x 48 mm x 8 mm) flat plate heat pipe. Rectangular grooves with converging cross section along the length act as the wicking structure. A converging cross section was designed to enhance the capillary force and to demonstrate the capability of additive …

A Study of the Macroinvertebrate Drift in the Des Moines River
… later. Samples were taken in a Wildco, 33 cm X 48 cm, 491 micron mesh drift net. Findings. Thirty-one taxa were sampled above the reservoir, while twenty-three were sampled below the reservoir. Total number of organisms per cubic meter were calculated. A decrease in the total number per cubic …

L1 adaptive control augmentation system for the X-48B Aircraft
… adaptive control methodology to a model of the X-48B Blended Wing Body aircraft. We explicitly verify the performance bounds of the adaptive flight control system at various flight conditions. We demonstrate that the resulting L1 adaptive controller does not require tuning or redesign from one …
