A Discrete Geometric Optimal Control Framework for Systems with Symmetries [PDF]
, 2007 This paper studies the optimal motion control of mechanical systems through a discrete geometric approach. At the core of our formulation is a discrete Lagrange-d’Alembert- Pontryagin variational principle, from which are derived discrete equations ...

Statistical representation of mountain shading [PDF]
, 2004 International audienceShadows cast by the mountains themselves have a strong influence on the surface energy balance of mountainous regions. If the influence of shadows is to be included on sub-grid scales in a surface energy balance model, a statistical

Experimental results of a terrain relative navigation algorithm using a simulated lunar scenario [PDF]
, 2015 This paper deals with the problem of the navigation of a lunar lander based on the Terrain Relative Navigation approach. An algorithm is developed and tested on a scaled simulated lunar scenario, over which a tri-axial moving frame has been built to ...

Comparative analysis of the differences between using LiDAR and contour-based DEMs for hydrological modeling of runoff generating debris flows in the Dolomites [PDF]
, 2015 Present work aims to explore the differences in hydrological modeling when using digital elevation models (DEMs) generated by points from LiDAR surveys and those digitized on the contour lines of the regional technical map (RTM) and their relevance for ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

DEVELOPMENT OF A DIGITAL ELEVATION MODEL OF KARA-BOGAZ-GOL BAY
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020 The article presents the results of the efforts to create a digital elevation model of Kara-Bogaz-Gol Bay. The informational background for the digital elevation model was maps of 1:200 000 and 1:100 000 scales. The digital elevation model was created by

Mapping Terrestrial Impact Craters with the TanDEM-X Digital Elevation Model [PDF]
, 2013 The TanDEM-X mission generates a global digital elevation model (DEM) with unprecedented properties. We use it for mapping confirmed terrestrial impact craters as listed in the Earth Impact Database.
