Currents that Puncture
Currents That Puncture is a poetic response to my personal experiences and study of literature over the past two years. My writing of poetry began as a means of understanding my childhood, adolescence and adult self. Thus, the persona of each poem is experiencing a process of self discovery. While …

Currents through the Golden Gate
… structure and two dimensional hodographs. Tidal currents appear to be hydraulically driven. Mean flow and transport were directed at 110 deg T at 23 cm/s and 45 cu.m/s; indicative of the two dimensional structure of the Golden Gate. Mean energy fluxes at the site were 30,000 W for kinetic energy …

Spin Currents in Organic Semiconductors
Organic semiconductors have recently been found to have a comparably large spin diffusion time and length. This makes them ideal candidates for spintronic devices. However, spin injection, transport and detection properties in organic materials have yet to be fully understood. This work studies …

Radiating instability of nonzonal ocean currents
… of the ocean away from the swift boundary currents. The energy radiation due to the temporal growth of non-trapped (radiating) disturbances in such a boundary current is thought to be one of the main sources for the described variability. The problem of stability of an energetic current, …

Harmonic analysis of transformer excitation currents
Transformer core nonlinearity has been a subject of research in electrical power engineering for many decades. An accurate and simple transformer model that takes into account its iron saturation appears to be lacKing The objective of this thesis is to propose a voltage-dependent model of …

Pullback of currents by meromorphic maps
… establish the existence of appropriate invariant currents (a generalization of measures), and then use them to construct invariant measures. To this end, it is important to know what currents can be pulled back or pushed forward by a map $f$. In my dissertation, based upon a regularization theorem …

Viscous fingering instabilities and gravity currents.–—
… viscosity. For single-layer viscous gravity currents with constant volumes, an analytical solution is available, which is known to be stable. By means of a numerical linear stability analysis, it is shown here that more general currents, with volumes growing as power laws in time, are stable …

Interface pinning of CO₂ gravity currents
Carbon capture and storage (CCS) is widely regarded as a promising tool for reducing global atmospheric carbon dioxide (CO₂) emissions, while allowing continued use of fossil fuels in the 21st century. In CCS, CO₂ is captured at point sources such as coal power plants and injected deep underground …

Aquatic gravity currents through emergent vegetation
… effects of aquatic vegetation on these currents. This study investigates the dynamics of lock-exchange flows, a particular class of density currents, propagating through rigid emergent vegetation. First, previous mathematical formulation is extended to develop theoretical models of …

Sheath currents, sheath losses, induced sheath voltages and apparent conductor impedances of metal sheathed cables carrying alternating currents
… it is proposed to consider sheath voltages, currents and losses and line constants for one or two circuits of single conductor cables with non-magnetic metallic sheaths. Residual earth currents, abnormal sheath voltages during failures, sheath proximity losses, and the results of special …

Dynamics of North Atlantic western boundary currents
… probe the dynamics of these two western boundary currents. First, to diagnose the dynamical balance of the Gulf Stream, a depth-averaged vorticity budget framework is developed. This framework is applied to observations and a state estimate in the subtropical North Atlantic. Budget terms indicate …
