Particulate matter emitted from two direct injection engines has been characterized by morphology, volatility, mass-mobility exponent, effective density, and size distribution using tandem measurements from a centrifugal particle mass analyzer (CPMA) and differential mobility analyzers (DMA). The...
Each individual chromatogram is typically very sparse, especially when coupled with a technique such as mass spectrometry. Only a small portion of the recorded data actually contains potentially useful information. Since the inclusion of irrelevant information will have detrimental effects upon...
Predicting the time for which a petroleum mixture has been exposed to weathering effects could have many applications. Historically, research on the evaporation rates of hydrocarbon mixtures has focused on forensic oil spill identification. Relatively little attention has focused on estimating...
