The North American rail system requires billions of dollars annually to be maintained in proper working order. Therefore, it is critical that maintenance is performed on the right components, at the right time, and in the ...

A method is presented for evaluating the effect of soil-structure interaction on the dynamic response of nonlinear building-foundation syste~s subjected to random seismic excitations. Uncertainties in the building-foundation ...

A number of destructive earthquakes have occurred in the central United States on the New Madrid Fault at the beginning of the 19th century. In the eight central U.S. states included in this investigation, rivers intersect ...

Determination of the in situ shear strength of granular materials is an expensive and time consuming endeavor using traditional "detailed" evaluation techniques. The development of several "rapid" evaluation devices has ...

The reaction of organic compounds with aqueous chlorine was examined before and after adsorption on an activated carbon bed. An extract of humic acid from peat soil was used as the organic compound in the first part of the ...

Wireless smart sensor networks have become an attractive alternative to traditional wired sensor systems in order to reduce implementation costs of structural health monitoring systems. The onboard sensing, computation, ...

While the state of Illinois has been recycling Reclaimed Asphalt Pavement (RAP) material into hot-mix asphalt (HMA) since 1980, there continues to be questions regarding the correct approach to design HMA with RAP. The ...

Biological hydrogen production is considered one reasonable alternative for generating H2 as a fuel that can be linked to electricity production in standard fuel cells. However, the molar yields are currently too low to ...
