by numerical simulations of matter distribution in the universe at different times through the age of the universe.

improve numerical simulations of many - body systems.
We are talking about very
coarse numerical simulations with largely guessed inputs and a lot of missing physics, not blanket - bans of all poor models everywhere.
Their work often
entails numerical simulations of the growth of the universe, handling extremely large sets of data, or the design of next - generation instruments.
An international team, including in particular a French researcher at the Lagrange Laboratory, now proposes a completely different scenario,
using numerical simulations partly run at the Mésocentre Sigamm at the Observatoire de la Côte d'Azur.
Recent numerical simulations suggested the lake formation is due to the cold - trapped methane accumulated in the polar region, and predicted prominent clouds will form within about two (Earth) years while lake levels will rise over the next fifteen years due to the seasonally varying solar radiation on Titan.
The GPI imaging furthermore clearly resolve the disk gap, allowing us to measure its width (~ 5 AU) and depth (~ 50 %) and thereby facilitating direct comparison with
detailed numerical simulations of planets forming in circumstellar disks.
The team
performed numerical simulations of planetary migration that generated the Kepler - 223 system's current architecture, which is similar to the migration suspected for planets of our outer solar system, Jupiter, Saturn, Uranus, and Neptune.
Recent
numerical simulations suggest the coupling between the stratospheric and tropospheric circulations has practical applications for weather forecasting and also implications for tropospheric climate change (see text on Climate Change, below).
«The explanation that we came up with — which people who
do numerical simulations have been suggesting for a long time — is that whatever this reservoir is with primitive helium, it must be really dense so that only the hottest, most buoyant plumes can entrain some of it to the surface,» Jackson said.
«It is the existence of Majoranas that gives rise to this quantized differential conductance,» says Liu, who
ran numerical simulations to predict the results of the experiments on UMD's Deepthought2 supercomputer cluster.
For these comparative studies I applied both simple model calculations and massive three - dimensional
direct numerical simulations on supercomputers.
These
expensive numerical simulations used state - of - the - art codes and took several months on the Institute's supercomputer LOEWE,» says Dr. Yosuke Mizuno, lead author of the study.
«But now, armed with new and better data, more
sophisticated numerical simulations, and highly integrated investigations in the lab and the field, Earth's oxygenation history seems much longer and more dynamic than envisioned before, and we are getting closer to understanding the mechanisms behind such change.»
The researchers compared the results of small -
scale numerical simulations of colliding rock and dust particles to the composition of meteorites.
Traditional, bottom - up detector characterization methods provide one way to model underlying detector physics, and generate ever more
faithful numerical simulations, but this approach... ▽ More As astronomical observations from space benefit from improved sensitivity, the effectiveness of scientific programs is becoming limited by systematics that often originate in poorly understood image sensor behavior.
In addition, data analysis techniques and instrument concepts are critically assessed so that high - resolution data can serve as a benchmark
for numerical simulations of granulation and sunspots.
«It is the first
time numerical simulations of binary black holes are used directly to estimate the parameters of a binary and, in this paper, it is proved that this can be done to the highest accuracy,» Lousto said.
Namely, it is hard to fingerprint when
different numerical simulations give different responses... Just seeing for example that the troposphere warms up more than the stratosphere, doesn't mean much.
In an open access paper just published in the Physics of Plasmas journal, we investigate the beam quality for such a micro accelerator, by running
complex numerical simulations.
Another paper published earlier this year presented the results of
numerical simulations providing a range of possibilities for the mass and orbit for such a hypothetical planet, that could account for the observed clustering of eKBO orbits.
The researchers are now working with other collaborators to benchmark their experimental results
against numerical simulations of the plating process in simple model systems.
(2) A
complete numerical simulation of the motions taking place in the outer core would make it necessary to cover a wide range of scales with a very small time step, which is out of reach with current capabilities.
To create a high - resolution CT of Earth, French used very
accurate numerical simulations of how seismic waves travel through the mantle, and compared their predictions to the ground motion actually measured by detectors around the globe.
«By combining experimental measurements and
theoretical numerical simulations, we established guidelines for controlling the charge of nanoparticles and obtaining catalysts having maximum efficiency,» explains Stefano Fabris (CNR - IOM / SISSA), one of the study authors.
Engineers at the University of California, San Diego, have completed the first
comprehensive numerical simulation of skeletal muscle tissue using a method that uses the pixels in an image as data points for the computer simulation — a method known as mesh - free simulation.
Soon Thor Lim and colleagues from the A * STAR Institute of High Performance Computing found a way to combine electronic and optical effects into a
single numerical simulation model.
Their method directly compares data from the Laser Interferometer Gravitational - wave Observatory to cutting -
edge numerical simulations of binary black holes, including simulations performed at RIT.
Looking for a predictive parameter, the astrophysicists based their work on
3D numerical simulations, which use computers to reproduce the behavior of the magnetic field in the Sun's atmosphere as well as the formation of sunspots, where eruptions take place.
Previously he has
written numerical simulations to represent a wide variety of systems ranging from the microscopic deformation in the cogs and gears of machinery to the evolution of jellyfish.
The trouble is that
devising numerical simulations of such collision is particularly difficult due to the presence of two centres for the occurrence: the atomic level with the proton and at the positronium level.
Since this was first predicted in 1988, many research groups in the field have confirmed and
refined numerical simulations, while others used static compression techniques to explore the phase diagram of water at high pressure.
