We present experimental force and power measurements demonstrating that the power
required to propel an actively swimming, streamlined, fish-like body is significantly
smaller than the power needed to tow the body straight and rigid at the same speed
U. The…

Thin wires are attached on the outer surface and parallel to the axis of a smooth
circular cylinder in a steady cross-stream, modelling the effect of protrusions and
attachments. The impact of the wires on wake properties, and vortex-induced loads

We employ a three-dimensional, nonlinear inviscid numerical method, in conjunction
with experimental data from live fish and from a fish-like robotic mechanism, to
establish the three-dimensional features of the flow around a fish-like body swimming
in a straight line, and…

Direct numerical simulation is used to study the turbulent flow over a smooth wavy
wall undergoing transverse motion in the form of a streamwise travelling wave. The
Reynolds number based on the mean velocity U of the external flow and…

The design and construction of a biomimetic flapping
foil autonomous underwater vehicle is detailed. The vehicle was
designed as a proof of concept for the use of oscillating foils as
the sole source of motive power for a cruising and…

This dissertation is an historical inquiry into the concomitant transformations of architectural discourse and the discipline of architecture in America. It proceeds on the theoretical assumption that the documents produced and used in architecture not only reflect but constitute architecture…

This thesis traces the development of American bacteriology during the first quarter of the twentieth century. While bacteriology experienced a period of rapid growth, an enduring disciplinary anxiety equally characterized the field. In particular, bacteriologists feared increasing specialization and conceptual…
