, 2005 We present a new method for computing an optimal deformation between two arbitrary surfaces embedded in Euclidean 3-dimensional space. Our main contribution is in building a norm on the space of surfaces via representation by currents of geometric measure theory.

Current developments in surface electromyography
Turkish Journal of Medical Sciences, 2023 Background/aim: Surface electromyography (surface EMG) is a primary technique to detect the electrical activities of muscles through surface electrodes. In recent years, surface EMG applications have grown from conventional fields into new fields. However, there is a gap between the progress in the research of surface EMG and its clinical acceptance ...

Wave–current interaction on a free surface [PDF]
Studies in Applied Mathematics, 2021 AbstractThe classical water wave equations (CWWEs) comprise two boundary conditions for the two‐dimensional flow on the free surface of a bulk three‐dimensional (3D) incompressible potential flow in the volume bounded by the free surface, which itself moves under the restoring force of gravity.

A novel drifter designed for use with a mounted Acoustic Doppler Current Profiler in shallow environments [PDF]
, 2013 We present a novel design for a surface drifter, mounted with a pulse-coherent Acoustic Doppler Current Profiler (ADCP) for measuring near-surface (depths 0.18-1 m) flows.

Rotating gravity currents: small-scale and large-scale laboratory experiments and a geostrophic model [PDF]
, 2007 Laboratory experiments simulating gravity-driven coastal surface currents produced by estuarine fresh-water discharges into the ocean are discussed. The currents are generated inside a rotating tank filled with salt water by the continuous release of ...
