1. A Natural Interpretation of Classical Proofs
Abstract : In this thesis we use the syntactic-semantic method of constructive type theory to give meaning to classical logic, in particular Gentzen's LK.We interpret a derivation of a classical sequent as a derivation of a contradiction from the assumptions that the antecedent formulas are true and that the succedent formulas are false, where the concepts of truth and falsity are taken to conform to the corresponding constructive concepts, using function types to encode falsity.

2. Quantum Chemical Studies of Aromatic Substitution Reactions
Abstract : In this thesis, density functional theory (DFT) is used to investigate the mechanisms and reactivities of electrophilic and nucleophilic aromatic substitution reactions (SEAr and SNAr respectively). For SEAr, the σ-complex intermediate is preceded by one (halogenation) or two (nitration) π-complex intermediates. READ MORE

3. Quantum Chemical Studies of Chemotherapeutic Drug Cisplatin : Activation and Binding to DNA
Abstract : The serendipitous discovery of the potent cytotoxic properties of cisplatin brought about a revolution in the treatment of certain types of cancer, but almost fifty years later, there still remain unknown areas in the chemistry of cisplatin. There are questions regarding which form of the drug reaches its DNA target, or why certain DNA sequences are more preferred than others for reaction with cisplatin. READ MORE

4. Logic program synthesis using schema instantiation in an interactive environment
Abstract : The research presented herein proposes a method of program synthesis based on a recursive program schema and performed with an explicit incremental plan as the core of the synthesis. A partial prototype has been built in order to be able to actually perform syntheses according to the method. READ MORE

5. Structure and Dynamics in Transition Metal Perovskites — An Optical Spectroscopy Study
Abstract : Transition metal oxides with the perovskite structure exhibit a vast number of exotic properties due to the large number of competing degrees of freedom at the Fermi surface. Together with couplings between and correlations within these degrees of freedom, this class of materials is of high interest from both a practical and theoretical point of view. READ MORE
