Terrain modelling of the complex volcanic terrain of Ischia Island, Italy

Canadian Journal of Remote Sensing, 2009
A high-resolution digital elevation model (DEM) (2 m spacing) is used in an attempt to model the volcanic terrain of Ischia Island (~150 ka ≥ age ≥ AD 1302). Ischia Island consists of a high-relief, resurgent central-western sector, a western sector affected by landslides related to the resurgence, and an eastern, lowland sector in which a volcanic ...

Terrain Modelling from Feature Primitives

, 2015
We introduce a compact hierarchical procedural model that combines feature‐based primitives to describe complex terrains with varying level of detail. Our model is inspired by skeletal implicit surfaces and defines the terrain elevation function by using

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Mean gust factors in complex terrain

Meteorologische Zeitschrift, 2004
Gust factors are analyzed for wind speeds greater than 10 m/s in a large set of data from automatic weather stations in the complex terrain of Iceland. The mean gust factors appear to be independent of the static and dynamic stability of the atmosphere ...
