Characterizing wind gusts in complex terrain [PDF]
Atmospheric Chemistry and Physics, 2019 Wind gusts are a key driver of aerodynamic loading, especially for tall structures such a bridges and wind turbines. However, gust characteristics in complex terrain are not well understood and common approximations used to describe wind gust behavior ...

An Optimization Framework for Wind Farm Design in Complex Terrain
Applied Sciences, 2018 Designing wind farms in complex terrain is an important task, especially for countries with a large portion of complex terrain territory. To tackle this task, an optimization framework is developed in this study, which combines the solution from a wind ...

TSIE: Robust Blind Locomotion Learning for Bipedal Robots via Terrain and State Implicit-Explicit Estimation [PDF]
BiomimeticsRobust blind locomotion over complex unstructured terrains relies on accurate estimation of robot states and surrounding terrain geometry. However, under real-world deployment conditions without exteroceptive perception, it remains challenging to ...

On the Expected Complexity of Voronoi Diagrams on Terrains [PDF]
ACM Transactions on Algorithms, 2012 We investigate the combinatorial complexity of geodesic Voronoi diagrams on polyhedral terrains using a probabilistic analysis. Aronov et al. [2008] prove that, if one makes certain realistic input assumptions on the terrain, this complexity is Θ( n + m √ n ) in the ...

Arches: a Framework for Modeling Complex Terrains [PDF]
Computer Graphics Forum, 2009 AbstractIn this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric discrete data structure that stores the different materials and an implicit representation for sculpting and reconstructing the

Advice complexity of treasure hunt in geometric terrains [PDF]
Information and Computation, 2021 Treasure hunt is the task of finding an inert target by a mobile agent in an unknown environment. We consider treasure hunt in geometric terrains with obstacles. Both the terrain and the obstacles are modeled as polygons and both the agent and the treasure are modeled as points.
