Energy Performance and Radial Force of Vertical Axis Darrieus Turbine for Ocean Energy
Energies, 2020 Vertical axis Darrieus turbine is the key component for ocean energy conversion and utilization. In the present work, the energy performance, flow pattern, and radial force for a vertical axis Darrieus turbine were investigated.

The Steady Motion of a Symmetric, Finite Core Size, Counterrotating Vortex Pair [PDF]
, 1994 The steady motion of a symmetric, finite core size, counterrotating vortex pair is characterized by circulation r, a velocity V, and a spacing 2x_∞. In the classical limit of a point vortex, the normalized velocity, vx_∞/r, is 1/(4π).

Breast Cancer Research, 2019 Background Circulating tumor cells (CTCs) represent a temporal “snapshot” of a patient’s cancer and changes that occur during disease evolution. There is an extensive literature studying CTCs in breast cancer patients, and particularly in those with ...

Physical Review E, 2009 A particle diffusing around a point of stable mechanical equilibrium in a static but non-conservative force field enters into a steady state characterized by circulation in the probability flux. Circulation in such a Brownian vortex is not simply a deterministic response to the solenoidal component of the force, but rather reflects an interplay between

Towards a Serious Game to Help Students Learn Computer Programming
International Journal of Computer Games Technology, 2009 Video games are part of our culture like TV, movies, and books. We believe that this kind of software can be used to increase students' interest in computer science.

From Vortex Layers to Vortex Sheets
SIAM Journal on Applied Mathematics, 1992 Summary: This paper shows that the solution of the Birkhoff-Rott equation for the vortex sheet can be approximated, for short times, by the solutions of the Euler equation for a thin vortex layer of vorticity, when its thickness vanishes and its verticity intensity diverges suitably.

Profiling protein expression in circulating tumour cells using microfluidic western blotting
Nature Communications, 2017 Circulating tumour cells (CTCs) are rare cells found in the blood of certain cancer patients. Here, the authors develop a cytometry tool that appends a microfluidic western blot to a CTC isolation workflow and apply it to profile a panel of proteins in ...

Inventions, 2022 Floating offshore structures (FOS) must be designed to be stable, to float, and to be able to support other structures for which they were designed. These FOS are needed for different transfer operations in oil terminals.

Interface Focus, 2015 Marine propellers display several forms of cavitation. Of these, propeller-tip vortex cavitation is one of the important factors in propeller design. The dynamic behaviour of the tip vortex is responsible for hull vibration and noise. Thus, cavitation in the vortices trailing from tips of propeller blades has been studied extensively.
