Investigation of RFID Readability for License Plates in Static and Motion Testing Srinivasan Venkatesan, University of Nebraska, 2011 Adviser: Robert E. Williams The most important function of RFID in vehicle tracking is to store information concerning tagged elements in order to improve the overall performance of movable asset management.

Upon the Client's request, the site investigation program included the exploration of site subsurface conditions at the construction area through the drilling of four boreholes: two to a depth of m each and two to a depth of m each below the existing ground level.

Jul 30, 2013· Despite this favourable situation for geophysics, exploration for coal in many countries mainly relies on drilling. The main reason for this is that when compared to petroleum exploration, coal exploration is concerned with much shallower targets (typically less than 2–300 m for open pit mining and less than about 1000 m for underground mining).

Purpose of the Geotechnical Investigation and Recommendations Manual The "Geotechnical Investigation and Recommendations Manual" has been prepared by the NCDOT Geotechnical Engineering Unit to provide investigators and designers with documentation for, and a reference to, the requirements for subsurface investigations and recommendations.

What methods are utilized in Phase 2 Environmental reports? AAI conducts Phase 2 ESAs at sites where there is known or significantlypotential soil and/or groundwater contamination. These reports are typically limited in nature and are usually the result of a Recognized Environmental Condition being found in a Phase I report during a real estate transaction, or prior to an owner listing a ...

Sinkhole location or void detection surveys are conducted most often in karst limestone areas. However, sinkhole detection and void location investigations may also be recommended in areas with soft soil, in areas where water or sewer pipes have broken, after a flood to check for flood damage, or where mining or other surface or subsurface ...

Site investigation should be organized to obtain all possible information toward a thorough understanding of the subsurface condition and probably foundation behavior. Background Information before Subsurface Investigation. Before actual field investigation is started, the information should, whenever possible, be collected on:

Jun 17, 2019· Lithium mining typically involves dissolving and reprecipitating either surficial salts from salt pans or solution mining of subsurface salt deposits. Instead of big holes in the ground, the impact is the construction of large surface area evaporation ponds.
