Researchers seek to identify dry lake bed deposits on Mars, if present. Primary tools in this search include the 1996 Mars Global Surveyor Thermal Emission Spectrometer (TES) and the 2001 Mars Odyssey multi-channel radiometer THEMIS. Interpretations are based on a comparison of the recorded signatures to laboratory spectra. Texture affects both the shape and contrast of the spectral signatures ...

-Increasing returns to scale (RTS) is frequently postulated as affecting productivity in surface coal mining. However, it is not clear whether increased capital intensity or increased output is the relevant phenomenon. A ray-homothetic production function that incorporates the capital-labor mix and fixed site geology into the scale elasticity is presented and estimated with a micro (mine level)...
