To level the X- and Y-axes of the Model 520-W Geodetic Platform Tiltmeter, the user turns a knob that raises or lowers an invar screw by means of a worm gear assembly. One complete 360° turn of the knob turns the screw by 6°, or 1/60 of a revolution. The ½-inch diameter screw has a pitch of 40...
The Carnegie Institution of Washington has installed two Jewell Instruments Model 510 Geodetic Borehole Tiltmeters in the sea floor east of Japan. The scientists are attempting to establish long-term sea floor observatories in one of the world's most active earthquake zones. Each observatory...
...in its development, this technology may one day enable water treatment plants to purify water with ceramic membrane filters instead of harsh chemicals. , both assistant professors of civil and environmental engineering and geodetic science, and doctoral students Dong Chen and Mikko Lamminen described...

Carolyn Merry As algae flourishes in the five freshwater lakes every summer, satellite images show the water changing color from blue to green, explained Carolyn Merry, professor of civil and environmental engineering and geodetic science. When algae levels are too high, water takes on a foul taste...
...and environmental engineering and geodetic science at Ohio State University. That would mean that the interior Antarctic ice sheet does not seem to be contributing to sea level rise more than 1 millimeter per year. Shum said that a one-centimeter (0.4 inch) decrease in Antarctic ice sheet volume...
...scientists on the project include Toni Schenk, professor of civil and environmental engineering and geodetic sciences; Catherine Tremper, a former graduate student in geological sciences, and now an image processing consultant to the university; Sung Woong Shin, a postdoctoral researcher at BPRC...
...and geodetic science, first developed the software that fuses lidar data and aerial imagery to automatically map areas of complex shape and elevation, such as roads or cities. Impeyong Lee, a postdoctoral researcher at BPRC, is helping Schenk adapt the software code for ICESat. Tests in Ocean City in 2001...
Pump curve. A centrifugal pump's performance may be graphically shown in a characteristic curve which usually shows data relative to the total geodetic height, to the actual motor power (BHP), to the efficiency, to the NPSHr and to the positive head, information indicated in relation to the pump...
