On the use of nonlinear soil models On the use of nonlinear soil models

The basic definitions of, and the differences between, currently available soil models are reviewed. These models are applied to site response analyses where two depths and two levels of base input motion are considered. Computational results are presented and compared with regard to the effects of using different soil models on computed site response. Other implications resulting from...

Image enhancement through film recorder response contouring Image enhancement through film recorder response contouring

In contrast to the traditional recording from high-altitude aircraft of Earth images directly onto film in their inherently continuous analog form, a Landsat Earth resources satellite samples the ground image brightness and records it on a digital, electronic medium. Although digitization incurs several extra steps in the reproduction of the imagery, it permits manipulation or...

The development and application of a county-level geographic database The development and application of a county-level geographic database

The purpose of this paper us to describe the collection of land use data by remote sensing techniques, the incorporation of land use, soils and slope data into a geographic database, and an application of geographic database techniques to a county planning problem. Land use data were successfully interpreted from aerial photographs and incorporated in a geographic database along with...

Synchrotron radiation and its application to digital subtraction angiography Synchrotron radiation and its application to digital subtraction angiography

The intense synchrotron radiation produced at electron storage rings provides a new source of X-rays highly suited to iodine K-edge digital subtraction angiography. The high intensity and small angular divergence permit the radiation to be monochromatized by Bragg diffraction and made available in beams of small vertical size, of arbitrary horizontal width, and of tunable energy. The use...
