It was concluded that the acoustic emission technique may provide a positive solution to the existing problem of detecting small fatigue cracks in highway bridge structures.Vannoy, D. W.Maryland Univ.Ghorbanpoor, A.White, E. JVannoy, D. W., Ghorbanpoor, A., and White, E. J., Acoustic...
wavelengths. All light curves show a sudden decrease in flux around the 1,336th integration, simultaneous to a tilt event from one of the segments of the primary mirror20,21. In the NIRISS data, this can be independently identified through a small but detectable morphological change in the s...
For instance, Maryland Department of the Environment (MDE), Texas Commission on Environmental Quality (TCEQ), Virginia Department of Environmental Quality (VA DEQ), CARB of USA implement their own I/M programs on a regular basis to ensure desired air quality in designated urban areas. Evaluation...
This device can be used both in a laboratory environment with conventional batch sampling systems or for on-road testing as a compact emission measurement system. If this information was acquired during conventional laboratory emissions tests... X Tang,MB Dan - Sae International Powertrains, Fuels ...
This paper employs two approaches of causality testing in panels to examine the causal relationship between the CO2 emission and its impact factor. The first is to treat the panel data as one large stacked set of data, and then perform the Granger Causality test in the standard way, with ...
