Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulation
Download2016
Chambers, Don, Dixon, Timothy H., Bonin, Jennifer, van den Broeke, M. R., Yang, Qian, Ribergaard, Mads H., Mortensen, John, Myers, Paul G.
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland’s ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW),...

Crack Growth Behavior of Pipeline Steels under Variable Pressure Fluctuations in a Near-Neutral pH Environment
DownloadFall 2015
This research aims at understanding the crack propagation behavior of pipeline steels under variable pressure fluctuations in a near-neutral pH environment. Although pressure fluctuations have been recognized as the driving force for crack growth for more than two decades, the mechanisms...

Calibration of Fatigue Design Factors and Fatigue Life Reliability of Steel Highway Bridges Using WIM Databases
DownloadSpring 2015
Fatigue life assessment of steel highway bridges is crucial to maintain their safety. Researches are required to quantify uncertainties in loading, resistance, fatigue life prediction and improvement techniques. This study calibrates some fatigue code parameters and models fatigue loading...

Multi-Agent Simulation (MAS) is a widely used paradigm for modeling and simulating real world complex system, ranging from ant colony foraging to online trading. MAS describes a complex system by representing it as a collection of interactive and concurrent objects following a set of predefined...

The process of magnetospheric radiation belt electron transport driven by ULF waves is studied using a 2-D ideal MHD model for ULF waves in the equatorial plane including day/night asymmetry and a magnetopause boundary, and a test kinetic model for equatorially mirroring electrons. We find that...

Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Le, G. M., Wang, J. S., Lei, J., Rae, I. Johnathan
A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

Kabin, Konstantin, Rankin, Robert, Ozeke, Louis G., Degeling, Alex W., Mann, Ian R.
The adiabatic drift-resonant interaction between relativistic, equatorially mirroring electrons and narrowband, Pc 5 ultra low frequency (ULF) waves in the magnetosphere is investigated using a time-dependent magnetohydrodynamic (MHD) wave model. Attention is focused on the effect of a ULF wave...

Rankin, Robert, Trichtchenko, Larisa, Yuan, Xingqiu, Cairns, Iver H.
Recent simulation results have revealed that energetic electron bursts are produced cyclically at the shock reformation period upstream of reforming shocks and are qualitatively very different from the continuous beam expected from time-stationary shocks (Yuan et al., 2007a). This paper extends...

Resonant drift echoes in electron phase space density produced by dayside Pc5 waves following a geomagnetic storm
Download2008
Rankin, Robert, Degeling, Alex W.
The interaction between relativistic, equatorially mirroring electrons and Pc5 Ultra Low Frequency (ULF) waves in the magnetosphere is investigated using a numerical MagnetoHydroDynamic (MHD) model for waves and a test-kinetic model for electron phase space density (PSD). The temporal and spatial...
