Solid Waste Disposal Site Characterization Using Non-Intrusive Electromagnetic Survey Techniques And Geostatistics, Gary N. Kuhn, Wayne E. Woldt, David D. Jones, Dennis D. Schulte

Department of Biological Systems Engineering: Papers and Publications

Prior to the research reported in this paper, a site-specific hydrogeologic investigation was developed for a closed solid waste facility in Eastern Nebraska using phased subsurface characterizations. Based on the findings of this prior investigation, a surface based geoelectric survey using electromagnetic induction to measure subsurface conductivity was implemented to delineate the vertical and horizontal extent of buffed waste and subsurface contamination. This technique proved to be a key non-intrusive, cost-effective element in the refinement of the second phase of the hydrogeologic investigation.

Three-dimensional ordinary kriging was used to estimate conductivity values at unsampled locations. These estimates were utilized to …

Method And Apparatus For Objective Evaluation Of Patent Ambulation, Balance And Weight Bearng Status, Eric B. Lancaster, Michael F. Kocher

Department of Biological Systems Engineering: Papers and Publications

A walker is provided which is equipped with detectors for measuring various loads and torques placed thereon by a user including right side and left side loads as well as torque loads on the handles of the walker and having time and distance detectors to allow the ambulation status of a user to be progressively monitored by medical personnel.

Sol Probe And Method Of Obtaining Moisture,Temperature And Root Distribution Of A Soil Profile, Marvin Twersky, William E. Splinter, Bruce C. Sandhorst

Department of Biological Systems Engineering: Papers and Publications

To provide a profile of simultaneous moisture, temperature and root density characteristics at different depths of soil, a soil probe is inserted in the soil with a viewing and camera section extending above the soil. Similarly, the probe provides a profile of simultaneous moisture, temperature and presence of molds, insects or other foreign matter in grain or similar media including liquid as well as solid granulated material. The portion of the probe that is in the soil or other media includes a source of light or light conveyance and windows which transmit an image of the soil at various depths …
