Individually, ground-based, in situ observations, remote sensing, and regional climate modeling cannot provide the high-quality precipitation data required for hydrological prediction, especially over complex terrains. Data assimilation techniques can be used to bridge the gap between observations and models by assimilating ground observations and remote sensing products into models to improve ...
Bio-inspired legged robots have demonstrated the capability to walk and run across a wide variety of terrains, such as those found after a natural disaster. However, the survival of victims of natural disasters depends on the speed at which these robots can travel. This paper describes the need for adaptive gait tuning on an eight-legged robot, which will enable it to adjust its gait parameters...
In this paper, we present a simple and efficient method to represent terrains as elevation functions built from linear combinations of landform features (atoms). These features can be extracted either from real world data-sets or procedural primitives, or from any combination of multiple terrain models. Our approach consists in representing the elevation function as a sparse combination of prim...
We describe two (1 + ε)-approximation algorithms for computing the Fréchet distance between two homeomorphic piecewise linear surfaces R and S of genus zero and total complexity n, with Fréchet distance δ. 1. A 2 (( n+ Area(R)+Area(S) (εδ)2 )2) time algorithm if R and S are composed of fat triangles (triangles with angles larger than a constant). 2. An O(D/(εδ)2) · n + 2O(D/(εδ)) time algorithm...
Prior to the arrival of the Dawn spacecraft at Ceres, the dwarf planet was anticipated to be ice-rich. Searches for morphological features related to ice have been ongoing during Dawn's mission at Ceres. Here we report the identification of pitted terrains associated with fresh Cerean impact craters. The Cerean pitted terrains exhibit strong morphological similarities to pitted materials previo...
Robots’ visual perception is a field that is gaining increasing attention from researchers. This is partly due to emerging trends in the commercial availability of 3D scanning systems or devices that produce a high information accuracy level for a variety of applications. In the history of mining, the mortality rate of mine workers has been alarming and robots exhibit a great deal of potentials...
Mapping Textures on 3D Terrains: A Hybrid Cellular Automata Approach. (December 2005) Swapnil Sinvhal, B.Arch., Indian Institute of Technology, Roorkee, India Chair of Advisory Committee: Dr. John Keyser It is a time consuming task to generate textures for large 3D terrain surfaces in computer games, flight simulations and computer animations. This work explores the use of cellular automata in ...
Control of legged locomotion across uneven terrain is poorly understood from a theoretical perspective, despite strong relevance to clinical and robotic applications. Gait research has typically examined locomotion on smooth and level surfaces with uniform steps. Identifying key gait parameters that permit agile locomotion across uneven surfaces could lead to a clearer understanding of control ...
