Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...

Behaviour of Plutonium, Rare Earth Elements and Elements of the Platinum Group in Vitreous Phosphate Composites During Liquid HLW Vitrification
The methods of γ-spectrometry, γ-scanning, α-radiography, optical microscopy, x-ray phase and x-ray fluorescent analyses were used to study the behaviour of Pu, La, Ce, Nd, Sm, Ru, Rh,...

The Application of Computerized Tomography for Determining Material Properties
X-ray computerized tomography (CT) is an imaging technique that has been used by the medical community for a number of years and is well documented. However, the adaption of this technique...

The Application of Vertical Seismic Profiling and Cross-Hole Tomographic Imaging for Fracture Characterization at Yucca Mountain
In order to obtain the necessary characterization for the storage of nuclear waste, much higher resolution of the features likely to affect the transport of radionuclides will be required...

Sounding Out Buried Waste
Geophysical diffraction tomography (GDT) is a new remote sensing technique for quantitative high-resolution subsurface imaging. It is similar to optical holography where long wavelength...

Vertical Transport in the Vadose Zone by Fingering
Water containing contaminants may infiltrate through the vadose zone as a series of fingers which result from a hydrodynamic instability initiated at an interface in which a fine textured...

Applications of X-Ray Imaging in Soil Mechanics
This paper presents a summary of the principles of methods to observe the detailed patterns of local deformation within a soil mass: stereophotogrammetry, polaroscopy, infrared tomography...

Demands and Means for Construction Innovation
Increasing complexity of the facilities owners need, increasing concern by owners regarding the cost effectiveness of investments in constructed facilities, and growing capability and...

Probing Concrete with Radio Waves
Electromagnetic probing can be used to assess the integrity of concrete cofferdam seals. Data are taken using high-frequency transmitter and receiver antennas installed in separate boreholes...

Three-Dimensional Analysis of Spinal Deformities
Present methods of obtaining quantitative measurements of spinal deformities for the clinical assessment of scoliosis from routine spine radiographs are inaccurate and inadequate. Two-dimensional...

Inspection and Tests of Welding of Highway Bridges
Inspection techniques developed by California Division of Highways for control of fabrication of welded highway bridges; management of inspection as well as step-by-step procedure followed;...
