Minimising wave drag for free surface flow past a two-dimensional stern

Free surface flow past a two-dimensional semi-infinite curved plate is considered, with emphasis given to solving for the shape of the resulting wave train that appears downstream on the surface of the fluid. This flow configuration can be interpreted as applying near the stern of a wide blunt ship. For steady flow in a fluid of finite depth, we apply the Wiener-Hopf technique to solve a linearised problem, valid for small perturbations of the uniform stream. Weakly nonlinear results found using a forced KdV equation are also presented, as are numerical solutions to the fully nonlinear problem, computed using a conformal mapping and a boundary integral technique. By considering different families of shapes for the semi-infinite plate, it is shown how the amplitude of the waves can be minimised. For plates that increase in height as a function of the direction of flow, reach a local maximum, and then point slightly downwards at the point at which the free surface detaches, it appears the downstream wavetrain can be eliminated entirely.

Henry Roth collection, 1959, 1992-1999.

The bulk of the collection consists of manuscripts by Roth of the first two volumes in his Mercy of a Rude Stream series. The manuscripts include editing notes by Roth and others. Several items of memorabilia are also included in the collection.

Henry Roth papers undated, 1918-1995

Papers include a large number of journals and notebooks, hundreds of fan letters, general correspondence, manuscripts by and about Roth, and publications by and about Roth. Papers also include various editions of his works and several annotated volumes of his personal reference library. Topical files contain photographs and items reflecting his interests and personal history.

Edgar Rice Burroughs' Martian Novels as an Early Paradigm of Racial Toleration

The Martian novels of Edgar Rice Burroughs (ERB) provide an early paradigm of racial toleration by displacing the heterogeneous race conflicts of the U. S. to an interplanetary location. There, the protagonist John Carter, representing Burroughs himself, introduces a level of racial acceptance and integration almost unheard of on the Earth of that era (the early twentieth century).
