Seventh-graders learn astrophysics through mixed-reality computer simulation
Seventh-graders astrophysics mixed-reality computer simulation
2016/4/13
Had the “learn’d astronomer’s” charts and theorems inspired the 19th-century writer Walt Whitman as much as strolling under the nighttime sky, Whitman might have become an astrophysicist instead of a ...
When certain massive stars use up all of their fuel and collapse onto their cores, explosions 10 to 100 times brighter than the average supernova occur. Exactly how this happens is not well understood...
A comparative study of a stochastic and deterministic simulation of strong ground motion applied to the Kozani-Grevena (NW Greece) 1995 sequence
simulation ground motion earthquake EGF-Kozani
2015/9/30
We present the results of a comparative study of two intrinsically different methodologies, a stochastic one and a deterministic one, performed to simulate strong ground motion in the Kozani area (NW ...
Three-dimensional interpretation of MT data in volcanic environments (computer simulation)
3D interpretation magnetotelluric data imaging monitorinc volcanoes magma chamber remote sounding
2015/9/28
The research is aimed, first, to find components of MT-fields and their transforms, which facilitate the imaging of the internal structure of volcanoes and, second, to study the detectability of condu...
Accelerometric radiation simulation for the September 26,1997 Umbria-Marche (Central Italy) main shocks
kinematic source model strong motion simulation Umbria-Marche main shocks
2015/9/28
We applied a hybrid stochastic-deterministic method to simulate the strong ground motion characteristics associated with the September 26, 1997 Umbria-Marche main shocks. One hundred different rupture...
A 1000-year simulation with the IPSL ocean-atmosphere coupled model
coupled climate model long-termclimate simulation oceanic overturning circulation model drift
2015/9/17
A 1000-year climate simulation is run with the ocean-atmosphere coupled model developed at the Institute Pierre-Simon Laplace (IPSL, Paris). No flux adjustment is used. The drift of the model is analy...
Numerical simulation of explosive volcanic eruptions from the conduit flow to global atmospheric scales
numerical modeling explosive volcanic eruptions conduit flow multiphase flow simulation stratospheric sulfate aerosol
2015/9/10
Volcanic eruptions are unsteady multiphase phenomena, which encompass many inter-related processes across the
whole range of scales from molecular and microscopic to macroscopic, synoptic and global....
A new chemistry option in WRF-Chem v. 3.4 for the simulation of direct and indirect aerosol effects using VBS:evaluation against IMPACT-EUCAARI data
WRF-Chem v. 3.4 direct and indirect aerosol VBS IMPACT-EUCAARI data
2015/9/10
A parameterization for secondary organic aerosol (SOA) production based on the volatility basis set (VBS) approach has been coupled with microphysics and radiative schemes in the Weather Research and ...
FEMSA: a finite element simulation tool for quasi-static seismic deformation modeling
faulting sources coseismic deformation finite element method PACS
2015/9/2
We set up a computational tool to numerically model static and quasi-static deformation generated by faulting
sources embedded in plane or spherical domains. We use a Finite Element (FE) approach to ...
Simulation of ionospheric error on GPS signals due to changes in the direction of mobile station positions in differential GPS
Ionosphere Ray-tracing dGPS Baseline
2015/8/27
Ionospheric propagation delay is one of the major sources of error in global positioning system (GPS) precision. Therefore, accurate estimation of the ionospheric delay is required to correct GPS posi...
Numerical simulation of lava flow using a GPU SPH model
GPGPU modeling HPC SPH hazard lava
2015/8/27
A smoothed particle hydrodynamics (SPH) method for lava-flow modeling was implemented on a graphical processing unit (GPU) using the compute unified device architecture (CUDA) developed by NVIDIA. Thi...
Computers have a remarkable ability to simulate natural and arti cial
phenomena. Industry, science, economic a airs and national security have
come to rely upon simulation as an essential technology...
We give an algorithm that computes the final state of certain growth models without computing all intermediate states. Our technique is based on a “least action principle” which characterizes the odom...
Stochastic simulation of soil water status on reclaimed land in northern Alber
E. geostatistics spatial variability semi-variogram uncertainty
2015/8/11
Studies of spatial variability and simulation of available soil water and extractable soil water are scarce and yet such data are essential in hydrologic and solute transport modeling. A study was con...
