In this talk, time-dependent free surface problem for the incompressible Navier-Stokes equations which describes the motion of viscous incompressible fluid nearly half-space are considered. We will di...
3D BUILDING GENERALIZATION BASED ON HALF-SPACE MODELING
Generalization Algorithms Building Three-dimensional GIS Visualization
2015/8/17
This article presents a novel approach for the automatic generalization of 3D building models with regard to a cartographic 3D visualization. Here, the goal is not to render realistic, but rather visu...
On Security of RASP Data Perturbation for Secure Half-Space Queries in the Cloud
half-space query data perturbation cloud computing
2012/6/14
Secure data intensive computing in the cloud is challenging, involving a complicated tradeoff among security, performance, extra costs, and cloud economics. Although fully homomorphic encryption is co...
Asymptotic description of solutions of the exterior Navier Stokes problem in a half space
Asymptotic description exterior Navier Stokes problem a half space
2011/8/25
Abstract: We consider the problem of a body moving within an incompressible fluid at constant speed parallel to a wall, in an otherwise unbounded domain. This situation is modeled by the incompressibl...

Propagation of torsional surface waves in heterogeneous half-space with irregular free surface
Torsional surface waves Irregularity Heterogeneous medium
2010/9/15
The effect of irregularity on the propagation of torsional surface waves in a heterogeneous, elastic half-space has been studied. The velocity equation has been derived. The velocities have been calcu...
Deformation due to a pressurized horizontal circular crack in an elastic half-space, with applications to volcano geodesy
displacement intrusion magma modelling sill theory
2014/4/9
We consider deformation due to sill-like magma intrusions using a model of a horizontal circular crack in a semi-infinite elastic solid. We present exact expressions for vertical and horizontal displa...
