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...
Pennelly, Clark, Hu, Xianmin, Myers, Paul G.
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°,...
Pennelly, Clark, Myers, Paul G.
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...
Design and Development of a Novel Tensile Testing Apparatus for Time-Resolved Betatron X-Ray Tomographic ImagingDownload
Arce-Borkent, Alvaro R., Richards, Tait, Senthilkumaran, Vigneshvar, Beier, Nicholas F., Zhou, Le, Moore, John A., Knudsen, K. Steven, Hussein, Amina E., Lipsett, Michael G.
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...

With the advent of IoT and trends toward intelligent manufacturing, having mechanical systems with integrated sensors is becoming more popular. Bearings are one of the components that have attracted more attention toward being integrated with sensors. Therefore, in this research, the design and...
Development Of A Model-Free Adaptive Steering Control For Autonomous Vehicles Path Tracking Using Cost-Based Gain Adaptation With Integral ActionDownload
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...
Numerical and experimental comparison of confinement effects on a Fully-Passive Oscillating-Foil TurbineDownload
Gunther, K., Mann, S., Dumas, G., Oshkai, P.
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...

Individuals in streams are constantly subject to predominantly unidirectional flow. The question of how these populations can persist in upper stream reaches is known as the “drift paradox.” We employ a general mechanistic movement-model framework and derive dispersal kernels for this situation....

We construct a continuum model for biological aggregations in which individuals experience long-range social attraction and short range dispersal. For the case of one spatial dimension, we study the steady states analytically and numerically. There exist strongly nonlinear states with compact...
