11. Nonlinear dynamics of strongly-bound magnetic vortex pairs
Sammanfattning : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. LÄS MER
12. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition
Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER
13. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors
Sammanfattning : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. LÄS MER
14. Developing Computational Methods for Moored Floating Wave Energy Devices
Sammanfattning : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. LÄS MER
15. Hydrodynamics and heat convection in channels with vibrating walls
Sammanfattning : In this work a combined analytical and numerical study of the non-linear effects of transverse wall vibrations on fluid flows are presented. Streaming motions and their effect on heat and mass transfer are investigated for a viscous fluid confined in an infinite channel with flexible walls. LÄS MER
