Automatic Steam Gathering Reduces Emissions at The Geysers
At the site of The Geysers, America's only geothermal power plant and the largest such plant in the world, the first completely computerized steam gathering system has been...

Estimated Magnitude of Acoustic Emissions in Soil
This paper presents a basic, phenomenological treatment of acoustic emission signal strength in soils. Using estimated values for soils, the approach does account for the order-of-magnitude...

Air Pollutants from Sewage Sludge Incineration
The disposal of sewage sludges is one of the unsolved chronic municipal problems. Further complications are added to the current trend of increasing construction of sewage treatment facilities...

Selection of Air-Quality Models
The basic question still exists as to what type of model to use and the validity of the predictions. Some of the data that affect the credibility of model predictions are dependent upon...

Acoustic Emission of Fiber Reinforced Plastics
Because most nondestructive test methods are not suitable for use with plastics, and in light of the poor performance record of FRP structures, a practical nondestructive test could be...
