Process-based numerical models are a useful tool for studying marine ecosystems and associated biogeochemical processes in ice-covered regions where observations are scarce. To this end, CSIB v1 (Canadian Sea-ice Biogeochemistry version 1), a new sea-ice biogeochemical model, has been developed...

A set of numerical simulations (with horizontal resolutions of 1/4 degrees and 1/12 degrees ) is conducted to study the Pacific Water pathway in the Arctic Ocean and the freshwater content in Beaufort Gyre. Passive tracer tags the Pacific Water entering through Bering Strait into the Arctic Ocean...

Surface geostrophic velocity fields derived from satellite altimetry between January 1993 and April 2014 are used to detect and investigate eddies in the North Atlantic between 40°N–55°N and 60°W–10°W. Focus is on a zonal section along 47°N, roughly at the boundary between the subpolar and the...

The amount of cross‐isobath freshwater exchange within the North Atlantic subpolar gyre is estimated from numerical modelling simulations. A regional configuration of the Nucleus for European Modelling of the Ocean model is used to carry out three simulations with horizontal resolutions of 1/4°,...

A high-resolution coupled ocean–sea ice model is set up within the Labrador Sea. With a horizontal resolution of 1/60◦ , this simulation is capable of resolving the multitude of eddies that transport heat and freshwater into the interior of the Labrador Sea. These fluxes strongly govern the...

High-resolution imaging of deformation processes in materials under load requires controllable and stable loading conditions and the ability to vary sample orientation relative to the imaging source. A novel tensile testing apparatus has been designed, developed, and characterized for...

This paper presents a model-free adaptive steering control algorithm for path tracking of autonomous vehicles. To design steering controllers for autonomous vehicle path tracking, a mathematical model is needed, but it may have high nonlinearity and complexity that increases computation time and...

Archimedes screw generators are a small-scale, eco-friendly hydropower technology that are commonly implemented in diversion schemes. The technology has been in use for thousands of years for pumping fluids and granular solids and so its design is largely influenced by Archimedes screw pump...

A numerical and experimental comparison of a fully-passive oscillating-foil turbine operating in different confinement levels is conducted to assert how well CFD-based FSI simulations can predict the performances of the turbine. It is found the present 3D URANS simulations match reasonably well...
