The research is to develop a sheet flow sampler to collect highway washoff and to operate in a highway roadside environment. The proposed sampler is expendable, simple, and cost effective. It will collect a predetermined depth of runoff (most commonly the first 1/2 inch of "first flush"), store it, and be removed and replaced by maintenance workers following rain events. The sampler will be its ...

In this proposal, the Viggen Project Team presents an elegant approach to developing a truly portable Graphical User Interface (GUI) for the Highway Capacity Software (HCS). Our approach is based on the emerging Internet-driven computing technology and will be totally platform-independent. The prototype will be developed using a programming language called Java and users will be able to execute ...

THERE IS A NEED FOR A RAPID, NON-DESTRUCTIVE METHOD TO TEST FOR PROPER STEEL PLACEMENT IN PORTLAND CEMENT PAVEMENTS. ISTHE GOAL OF THIS PROPOSED PROGRAM TO DEMONSTRATE THE FEASIBILITY OF USING SHORT-PULSE, GROUND-PENETRATING RADAR AS A MEANS OF RAPID STEEL LOCATION IN CONCRETE PAVEMENT. A GENERAL BACKGROUND IN GROUND-PENETRATING RADAR THEORY IS PRESENTED. LABORATORY AND FIELD MEASUREMENTS USING A ...

FOR CATHODIC PROTECTION SYSTEMS TO BE SUCCESSFUL IN MITIGATING CORROSION WITHOUT CAUSING HYDROGEN EMBRITTLEMENT OF PRESTRESSING STEEL, THE AMOUNT OF POLARIZATION OF THE EMBEDDED STEEL MUST BE VERY ACCURATELY CONTROLLED. PRESENTLY AVAILABLE EMBEDDED REFERENCE ELECTRODES DO NOT HAVE THE LONG TERM STABILITY OR RELIABILITY RE@UIRED TO MONITOR AND CONTROL THE AMOUNT OF POLARIZATION WITH THE ACCURACY RE ...

THIS PROJECT WILL RESEARCH AND DEVELOP A FLOOR MONITOR FOR QUICK DETERMINATION OF RADIOACTIVE CONTAMINATION. THE MONITOR WILL UTILIZE A NEW PORTABLE TECHNOLOGY (INCLUDING SUPPORT ELECTRONICS). IT WILL HAVE THE CAPABILITY TO MEASURE BETA CONTAMINATION BELOW 5000 DPM/100 CM SQUARED WHEN AVERAGED OVER ONE SQUARE METER AND COVER AN AREA AS LARGE AS SEVERAL SQUARE FEET PER SECOND. IT WILL ALSO BE CAPAB ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

We propose here to evaluate a variety of inorganic scintillators, including sodium iodide and bismuth germanate, for use in energy-sensitive neutron detectors. We will couple these crystals to photomultiplier tubes and measure the prompt response to inelastic neutron reactions with the scintillator atoms. To unfold the incident neutron energy distribution from the resulting signal pulse heights, ...
