We seek to conduct a comprehensive investigation of the dynamical mechanisms of vertical coupling over topography. • To construct a realistic model of the potential vorticity (PV) distribution on density layers across the Gulf Stream, generated from high-resolution density and velocity observations. • To demonstrate evidence of vertical coupling between the upper and lower layers in a hypothesi...

MilkyWay@home is a volunteer computing project that allows people from every country in the world to volunteer their otherwise idle processors to Milky Way research. Currently, more than 25,000 people (150,000 since November 9, 2007) contribute about half a PetaFLOPS of computing power to our project. We currently run two types of applications: one application fits the spatial density profile o...

Thalweg profiles are longitudinal profiles of the streambed elevation measured along the deepest portion of the stream. This technique has recently been advocated as a tool to monitor fish habitat in streams because profiles can provide useful information on such habitat, and measurements are both repeatable and independent of stream flow. However, a relation between fish abundance and metrics ...

We present an integrable solution for detection of defective sensor elements using sigma-delta-(Σ∆)modulation and a matched filter. The sensor element is stimulated using a pseudo random binary sequence (PRBS). The sensor signal is read out and the analog output is digitized using a Σ∆-modulator. The binary pulse density stream of the Σ∆-modulator is the output of the sensor system and thus sho...

Abstract Tidal and wind energy projects almost exclusively adopt horizontal axis turbines (HATs) due to their maturity. In contrast, vertical (VATs) have received limited consideration for large-scale deployment, partly because of earlier technology readiness level. This paper analyses the power density turbine arrays comprising aligned staggered configurations with decreasing spacing HATs VATs...
