1. Achievement tests and optimal design for pretesting of questions
Abstract : Achievement tests are used to measure the students' proficiency in a particular knowledge. Computerized achievement tests (e.g. GRE and SAT) are usually based on questions available in an item bank to measure the proficiency of students. READ MORE

2. Formal Languages and Automata in Computational Algebra
Abstract : This thesis is a collection of six papers in computational algebra. In particular, we study noncommutative Gröb- ner bases, SAGBI bases and similar algebraic objects which can be represented as a graph or an automaton. READ MORE

3. Skew-symmetric matrix pencils : stratification theory and tools
Abstract : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

4. Representation matters in cyclic proof theory
Abstract : Cyclic proof systems allowderivations whose underlying structure is a finite graph, rather than a well-founded tree. The soundness of cyclic proofs is usually ensured by imposing additional conditions beyond well-formedness. READ MORE

5. Extensions of the kernel method of test score equating
Abstract : This thesis makes contributions within the area of test score equating and specifically kernel equating. The first paper of this thesis studies the estimation of the test score distributions needed in kernel equating. READ MORE
