Recently, biomass has become an increasingly widely used energy resource. The problem with the use of is its variable composition. most important property that determines content and thus performance fuels such as heating value (HHV). This paper focuses on selecting optimal number input variables using linear regression (LR) multivariate adaptive splines approach (MARS) to create artificial neu...

The entry, descent, and landing (EDL) sequence of NASA's Mars 2020 Perseverance Rover will act as a seismic source known temporal spatial localization. We evaluate whether the signals produced by this event be detectable InSight lander (3,452 km away), comparing expected signal amplitudes to noise levels at instrument. Modeling is undertaken predict propagation acoustic (purely in atmosphere), ...

[1] We use the Mars Regional Atmospheric Modeling System (MRAMS) to simulate lake storms onMars, finding that intense localized precipitation will occur for lake size ≥10 km. Mars has a low‐density atmosphere, so deep convection can be triggered by small amounts of latent heat release. In our reference simulation, the buoyant plume lifts vapor above condensation level, forming a 20 km high opti...

[1] The Panoramic Camera (Pancam) investigation is part of the Athena science payload launched to Mars in 2003 on NASA’s twin Mars Exploration Rover (MER) missions. The scientific goals of the Pancam investigation are to assess the high-resolution morphology, topography, and geologic context of each MER landing site, to obtain color images to constrain the mineralogic, photometric, and physical...

High-resolution mapping by visible and near-infrared orbital spectrometers has revealed a diversity of hydrated mineral deposits on the surface of Mars. Quantitative analysis of mineral abundances within these deposits has the potential to distinguish depositional and diagenetic processes. Such analysis can also provide important constraints on the nature of putative global and local-scale mine...

Background: Orbital remote sensing observations over the past decade have shown Mars to host a great diversity of hydrous minerals, including clays, sulfates, zeolites, and opaline silica [1-3]. Though certain regions of Mars contain vast exposures of these minerals (e.g., clay minerals in Mawrth Vallis and Nili Fossae and sul-fates in the interior layered deposits of Valles Mari-neris), many o...

Introduction: The latitude dependent distribution [1-3] and non-uniform orientations [4-8] of young gullies on Mars suggest that their formation and modification are controlled by the activity of volatiles at or near the surface. Given the relative abundance of gullies and Mars' current thermal environment, CO 2 and H 2 O are the most likely candidates for contributing to gully evolution. Conte...
