Simulations of Rover Based Neutron Remote Sensing of Periglacial Features on Mars
Introduction: Results from Mars Odyssey's highenergy neutron spectrometer, and gamma ray spectrometer have shown that there is 15 to 20% ice in the top meter of Martian regolith at latitudes of +/-55 degrees [1,2,3]. This observation has been critical in understanding the nature of patterned ground on Mars [4]. The resolution of the ground ice maps generated from these instruments, however, is ...
متن کاملPunctual Coalescing
Compilers use register coalescing to avoid generating code for copy instructions. For architectures with register aliasing such as x86, Smith, Ramsey, and Holloway (2004) presented a polynomial-time approach, while Scholz and Eckstein (2002) presented an optimal, exponential-time approach together with a near-optimal, quadratic-time heuristic. Both methods scale poorly after aggressive live ran...
متن کاملPermafrost and Periglacial Processes
The microbial process of methane (CH4) production during the back-freezing of permafrost soils in autumn and the future fate of produced CH4 in the thawing phase of the following spring are not well understood. Long-term CH4 flux studies in the Lena Delta (Siberia) indicate that back-stored CH4 adds to the emission of newly-produced CH4 at the beginning of the vegetation period. Further field a...
متن کاملPermafrost and Periglacial Processes
Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant, in general terms, to permafrost thaw (therrnokarst). In this study, we test and calibrate seve...
