and is providing both visible and infrared imaging observations of the martian surface at two scales (18 m/p and 100 m/p respectively). IR observations are being conducted during both day and night. IR imagery records temperature variations, which are primarily due to differences in abundances of rocks, indurated materials , sand, and dust on the surface.(More)
We describe how we plan to convert a traditional data collection sensor and ocean model into a DDDAS enabled system for identifying contaminants and then reacting with different models, simulations, and sensing strategies in a symbiotic manner. The sensor is just as useful in water as it would be on Mars for material identification. A successful terrestrial(More)
1 Hippocampal synaptic activity is probabilistic and because synaptic plasticity depends on its history, the amount of information that can be stored at a synapse is limited. The strong correlation between the size and efficacy of a synapse allowed us to estimate the precision of synaptic plasticity. In an electron microscopic reconstruction of hippocampal(More)
We report on further developments of a hybrid numerical model to simulate wave-induced sediment transport. A 2D numerical wavetank (NWT) based on fully nonlinear potential flow (FNPF) equations is used to simulate fully nonlinear wave generation and propagation. A 3D Navier-Stokes model with large eddy simulation (LES) is coupled to the NWT to simulate(More)
We perform numerical simulations of wave generation by the potential flank collapse of the Cumbre Vieja Volcano (CVV; La Palma ,Canary Islands, Spain). Subaerial slide scenarios are first defined based on recent slope stability studies of CVV; the identified scenarios have smaller volumes than those proposed by Ward and Day (2001), in the pioneering work(More)
As demonstrated in the pioneering (but still controversial) work by Ward and Day (2001), the potential flank collapse of the Cumbre Vieja Volcano (CVV) on La Palma (Canary Islands) could result in a large tsunami having effects throughout the North Atlantic Ocean. While recent studies have suggested that such a collapse would likely result in more moderate(More)
We present the validation and application of a numerical model for the simulation of wave-induced sediment transport. Our approach is a one-way coupling of an inviscid flow model (i.e., a Numerical Wave Tank based on potential flow theory; NWT) to a Navier-Stokes solver, to simulate near bottom wave-induced turbulent boundary layer flows. Only(More)
Introduction: The Thermal Emission Imaging System (THEMIS) onboard the 2001 Mars Odyssey Orbiter began its Primary Mapping Mission in February, 2002; public access to the THEMIS standard data archive began in October, 2002. The archive includes the raw, calibrated, and derived images generated from the infrared and visible observations. THEMIS standard data(More)
Tsunami hazard assessment for future megathrust earthquakes requires that we understand the source mechanisms and tsunami generation processes for large historical events, such as the devastating Tohoku-oki tsunami of March 11 th 2011. Although associated with a Magnitude 9 earthquake, simulations of the tsunami based solely on this co-seismic source do not(More)
