Contact Pressure Distribution on Subgrade Soil Underlying Geocell Reinforced Foundation Beds

Spatial Correlation of Mechanical Properties of subgrade Soil for Foundation Characterization

A pressure-sensitive mat for measuring contact pressure distributions of patients lying on hospital beds.

The authors describe a novel system for sensing and displaying the distribution of contact pressure caused by a patient's lying on a hospital bed. The system includes a flexible, pressure-sensitive mat, electronics to activate the mat, a small computer to process data, and a color video display. The present prototypes can sense pressure at 1,536 discrete locations in a rectangular grid of 24 x ...

Geocell-Reinforced Crushed Stone Base for Low-Volume Roads

Crushed stone bases are widely used for low-volume roads. However, shear strength of the crushed stone materials can be vastly improved by confining the material in geocellular confinement systems or geocells. Geocells are 3-dimensional honeycomb-like structures. The objective of this study was to test a geocell design with crushed stone (AB-3) in-fill and a thin hot-mix asphalt (HMA) surface l...

Multiscale probability distribution of pressure fluctuations in fluidized beds

Analysis of flow in fluidized beds, a common chemical reactor, is of much current interest due to its fundamental as well as industrial importance. Experimental data for the successive increments of the pressure fluctuations time series in a fluidized bed are analyzed by computing a multiscale probability density function (PDF) of the increments. The results demonstrate the evolution of the sha...

Influence of Soil-industrial Effluents Interaction on Subgrade Strength of an Expansive Soil-a Comparative Study

The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a v...
