Alkylation of phenol with methanol over H-ZSM-5, H-Beta, H-Mordenite, H-USY and H-MCM-22
Alkylphenols are intermediates used in the synthesis of many important substances. The most significant of the commercially important lower alkylphenols are cresols (methyl phenols) and xylenols (dimethyl phenols). The main markets for alkylphenol products are nonionic detergents, phenolic resins, …

Robust regulation with H(2) or H(infinity) performance
In this thesis, three performance problems in linear control systems are studied. Robust regulation against steps and sinusoids is the first. Major results on this classic problem are rederived using only basic state-space ideas.

Homotopy algorithms for the H² and the combined H²/H<sup>∞</sup> model order reduction problems
The problem of finding a reduced order model, optimal in the H² sense, to a given system model is a fundamental one in control system analysis and design. The addition of a H<sup>∞</sup> constraint to the H² optimal model reduction problem results in a more practical yet computationally more …

Oxidative addition of N-H and O-H bonds to iridium: developing active catalysts for N-H and O-H additions to unsaturates
The oxidative addition of the N-H bond of both heterocyclic and acyclic amines and the O-H bond of phenols, water and carboxylic acids to iridium(I) trimethylphosphines complexes was studied and the reactivity of the resulting hydrido amido-, aryloxo- and carboxylato iridium(III) complexes was …

H and I
<p>This manuscript is an attempt to connect the personal myth I’ve fashioned out of a relationship with my dog with the larger role that dogs play in our consciousness and how this role alters our relationships with other humans. It is about my inability to comprehend, to see the truth behind these …

Vibrational Energies of the Hydrogen Bonds of H₃O₂⁻ and H₅O₂⁺
We approximate the vibrational energies of the symmetric and asymmetric stretches of the hydrogen bonds of the molecules H_3O_2^- and H_5O_2^+ by applying an improvement to the standard time-independent Born-Oppenheimer approximation. These two molecules are symmetric around a central hydrogen …
