A Discrete Geometric Optimal Control Framework for Systems with Symmetries [PDF]

open access: yes, 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 ...

A Method of Optimizing Terrain Rendering Using Digital Terrain Analysis

open access: yesISPRS International Journal of Geo-Information, 2021
Terrain rendering is an important issue in Geographic Information Systems and other fields. During large-scale, real-time terrain rendering, complex terrain structure and an increasing amount of data decrease the smoothness of terrain rendering. Existing

Application of Digital Terrain Model to volcanology

open access: yesAnnals of Geophysics, 2006
Three-dimensional reconstruction of the ground surface (Digital Terrain Model, DTM), derived by airborne GPS photogrammetric surveys, is a powerful tool for implementing morphological analysis in remote areas.

MODELING OF THE "PLAN DA MATTUN" ARCHAEOLOGICAL SITE USING A COMBINATION OF DIFFERENT SENSORS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Plan da Mattun is located at ~2200 metre above sea level in the Tasna valley in alpine south-eastern Switzerland. In this remote location, finds dating back to the time of Ötzi (3000 B.C.) were discovered by archaeologists from the University of Zurich.

Cellular-Automata model for dense-snow avalanches [PDF]

open access: yes, 2007
This paper introduces a three-dimensional model for simulating dense-snow avalanches, based on the numerical method of cellular automata. This method allows one to study the complex behavior of the avalanche by dividing it into small elements, whose ...
