Application of chemometric and experimental tools for monitoring processes of industrial importance
DownloadFall 2019
The common theme of this work was to investigate the relationships between multi-dimensional experimental data and the physical and chemical properties of certain reacting systems that have industrial relevance. Three particular systems of increasing complexity in terms of composition of the...

de la Mata, A. P., Harynuk, J. J., Sinkov, N.A.
Interesting real-world samples are almost always present as mixtures containing the analyte(s) of interest and a matrix of components that are irrelevant to answering the analytical question at hand. Additionally, the compounds comprising the matrix are usually present in far greater...

On the impact of drought-induced abiotic stress on the composition of Douglas-fir lignin for valorization
DownloadFall 2022
Rising interest in the transition to renewable energy, materials, and chemicals ushers biorefining strategies that effectively utilize all components of lignocellulosic biomass feedstocks. Concurrently, more frequent and severe drought brought on by accelerating climate change pose questions...

Simulation of Fire Debris for the Training of Chemometric Models for the Identification of Ignitable Liquids
DownloadSpring 2015
Arson is one of the most challenging crimes for forensic scientists to investigate. The variability in the composition of ignitable liquids, including changes in chemical composition during and after the fire, and the presence of pyrolysis products generated from burning substrates yields a very...

Understanding the Chemistry of Conversion of Model Compounds and Biomass by Hydrous Pyrolysis Based on Spectroscopic Data Using Data Fusion, Data Mining, and Chemometrics
DownloadFall 2019
Encoding the presence of multispecies in a complex system, difficulty in characterizing the physical constituents of the products with analytical instruments along with developing the causality or modeling between these groups are some major challenges in a complex system such as biomass...

Zalta, Edward N. , Linsky, Bernard
Logicism is a thesis about the foundations of mathematics, roughly, that mathematics is derivable from logic alone. It is now widely accepted that the thesis is false and that the logicist program of the early 20th century was unsuccessful. Frege's [1893/1903] system was inconsistent and the...
