A psychometric analysis of the Statistics Concept Inventory.
(2006)
A clearer picture of student understanding emerges when the item analyses are combined with analyses obtained using IRT methods. In particular, the nominal response model appears to be able to shed light on persistent ...
A comparison of solutions of a Boussinesq system and the Benjamin-Bona-Mahony equation.
(2000)
We compare solutions of a regularized Boussinesq model system for water waves to solutions of the Benjamin-Bona-Mahony equation. Both the system and the equation are obtained as formal approximations to the Euler equations ...
Digital signal processing on the unit sphere via a Ramanujan set of rotations and planar wavelets.
(2000)
We give a sufficient condition for a zonal function to be a strictly positive definite. A major result of this thesis is that we have proven Shreiner's result as a consequence of a more general representation-theoretic ...
