1. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction
Sammanfattning : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases. LÄS MER
2. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis
Sammanfattning : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. LÄS MER
3. A cryogradient sampling system for chemical analysis of polycyclic aromatic compounds (PAC) : studies of the gas phase-emitted PAC from automobiles
Sammanfattning : .... LÄS MER
4. Magnetic properties studied by perturbed angular correlations : fast timing circuits and a computer system for PAC
Sammanfattning : .... LÄS MER
5. Information-Theoretic Generalization Bounds: Tightness and Expressiveness
Sammanfattning : Machine learning has achieved impressive feats in numerous domains, largely driven by the emergence of deep neural networks. Due to the high complexity of these models, classical bounds on the generalization error---that is, the difference between training and test performance---fail to explain this success. LÄS MER
