Sequential alkylation of Hagemann's ester with methyl and
methallyl halides has been studied. Treatment of Hagemann's ester
with methyl iodide and sodium ethoxide gave a mixture of 21 and 25
in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium
t-butoxide afforded a mixture of 37 and...
This dissertation addresses object recognition in challenging settings, where distinct object classes are visually very similar (e.g., species of birds and insects) and/or access to training examples of object classes is limited (e.g., due to the associated high costs of data annotation). In this dissertation, we present a variety of...
Cordyceps is a genus of perithecial ascomycetes. It includes over 400 species
that are pathogens of arthropods and parasites of the truffle genus Elaphomyces. Based
on the morphology of cylindrical asci, thickened ascus apices and filiform ascospores,
it is classified in the Clavicipitaceae (Hypocreales), which also includes endophytes
and epiphytes...
An Invasive Plant Management Plan developed for Big Sur Land Trust, a non-profit conservation organization located on California's Central Coast, to guide its vegetation management activities and serve as a decision-support tool. The effort included the creation of a digital field data collection tool through Survey123 Connect, survey and data...
Both transportation costs and market values of woody biomass are strongly linked to the amount of moisture in the woody biomass. Therefore, managing moisture in the woody biomass well can lead to significant advantages in the woody biomass energy business. In this study, two prediction models were developed to estimate...
A detailed mechanism for the four-component RD387 gasoline surrogate developed by Lawrence Livermore National Laboratory has shown good agreement with experiments in engine-relevant conditions. However, with 1388 species and 5933 reversible reactions, this detailed mechanism is far too large to use in practical engine simulations. Therefore, reduction of the detailed...
This thesis examines the influence of Christian missions on Yung Wing (1828-1912) during the nineteenth century, when China was beginning to encounter the West. Yung was the first Chinese graduate student to enter an American institution of higher education (Yale College, 1854). As a Westernized Christian intellectual, he strove to...
Classification based on metathoracic wing venation does not
coincide with the existing higher classification of the family Scutelleridae.
The wings of the genera in the Scutellerinae possess a
similar general pattern of venation which is quite distinct from that
of Eurygasterinae, Odontoscelinae, Odontotarsinae, and Pachycorinae.
The Scutellerinae wings possess three...
Accurately predicting key combustion phenomena in reactive-flow simulations, e.g., lean blow-out, extinction/ignition limits and pollutant formation, necessitates the use of detailed chemical kinetics. The large size and high levels of numerical stiffness typically present in chemical kinetic models relevant to transportation/power-generation applications make the efficient evaluation/factorization of the chemical kinetic...
