CLUSTERING OF WALL GEOMETRY FROM UNSTRUCTURED POINT CLOUDS
Building Information Modeling Clustering Wall Building Point Clouds
2019/3/1
The automated reconstruction of Building Information Modeling (BIM) objects from point cloud data is still ongoing research. A key aspect is retrieving the proper observations for each object. After s...
An Unstructured Grid, Finite-Volume Coastal Ocean Model (FVCOM) System
Ocean Model (FVCOM) System Unstructured Gri
2015/7/23
The coastal ocean extends from the land-sea interface where freshwater enters the ocean through rivers and estuaries to beyond the continental shelf. Due in part to its shallow and complex bathymetry ...
An unstructured-grid, finite-volume, nonhydrostatic, parallel coastal ocean simulator
Nonhydrostatic Unstructured grid Parallel Internal gravity wave
2015/6/30
A finite-volume formulation is presented that solves the three-dimensional, nonhydrostatic Navier–Stokes equations with the Boussinesq approximation on an unstructured, staggered, z-level grid, with t...
Reconstruction of vector fields for semi-Lagrangian advection on unstructured, staggered grids
Interpolation Vector fields Unstructured Staggered grids Semi-Lagrangian advection
2015/6/30
Applying the semi-Lagrangian method to discretize the advection of momentum eliminates the Courant number constraint associated with explicit Eulerian momentum advection in coastal ocean models. Key s...
Numerical diffusion for flow-aligned unstructured grids with application to estuarine modeling
unstructured grid numerical diffusion grid generation grid alignment
2015/6/30
The benefits of unstructured grids in hydrodynamic models are well understood but in many cases lead to greater numerical diffusion compared with methods available on structured grids. The flexible na...

2015/6/23
This report presents a three-dimensional high-order Spectral Dierence solver suitable
for Large Eddy Simulation. The solver is based on the formulation of Sun et al. (2007)
implemented on unstructu...
Implications of mountain shading on calculating energy for snowmelt using unstructured triangular meshes
solar radiation shading mountains triangulated irregular networks unstructured mesh radiation modelling Canadian Rockies
2014/4/3
In many parts of the world, snowmelt energetics is dominated by solar irradiance. This is particularly the case in the Canadian
Rocky Mountains, where clear skies dominate the winter and spring. In m...
Unstructured Randomness, Small Gaps and Localization
Unstructured Randomness Small Gaps Localization
2010/10/29
We study the Hamiltonian associated with the quantum adiabatic algorithm with a random cost function. Because the cost function lacks structure we can prove results about the ground state. We find th...
