"Theoretical calculations" refers to using mathematical models and formulas to predict or figure out something without actually conducting real-world experiments or observations. It involves using logical reasoning and assumptions to come up with an understanding or explanation for a particular phenomenon or situation.
Full definition
New theoretical calculations are required to match the experimental accuracy, especially in view of planned upgrades and new experiments at even higher energy levels.
PNNL's Ping Yang at EMSL, DOE's Environmental Molecular Sciences Laboratory on the PNNL campus, took to EMSL's supercomputer Chinook to perform
theoretical calculations on the orange and blue structures.
The outstanding agreement of the synchrotron diffraction data with
theoretical calculations in describing the intralayer Ti - S interactions, supports the validity of these new - found differences for the long - range interactions across the interlayer gaps.
They corroborated their experimental spectra
with theoretical calculations of the amount of energy associated with argon entering and leaving the cages.
The reason for this —
as theoretical calculations of the Sinova group have shown — lies in the existence of certain valleys in the conduction band of the semiconductor material.
The device, described in the June 10 Nano Letters, can hold one trillion bits per square inch, and
theoretical calculations suggest that the system could remain thermodynamically stable for one billion years.
In the United States at the Nevada test site, radioactive elements moved 1.3 kilometers from their source in just 30 years: significantly more than what was predicted
from theoretical calculations.
Previously, the most precise measurement of the constant was indirect, relying on a measurement of the electron's magnetic properties and using
complex theoretical calculations to infer the constant's value.
Spectroscopy, for example, infers these changes from the way laser light interacts with electron clouds around atomic nuclei, and
requires theoretical calculations to turn these data into a picture of the nuclear geometry.
Theoretical calculations show that by harvesting the hot electrons, the maximum efficiency for hybrid - perovskite solar cells could increase from 33 to 66 percent.
Because presolar supernova graphite grains are isotopically similar in many ways to the SiC grains, the team also argues that the delayed formation timing applies generally to carbon - rich supernova dust, in line with some
recent theoretical calculations.
«In fact, this project is part of a larger effort by the Fermilab Lattice and MILC Collaborations to produce
precise theoretical calculations of the strong interaction effects for a range of important processes relevant to precision frontier experiments.
For instance, in simulations of how a drug couples to its target protein in the body, the computer performs
quantum theoretical calculations on those atoms in the target protein that interact with the drug.
The theoretical investigations also confirmed a result shown by
previous theoretical calculations that 2D Fe membranes should have a significantly enhanced magnetic moment.
Advanced theoretical calculations performed by the team provided detailed explanations of the transition paths from coesite to the four crystalline phases to post-stishovite.
In the 1960s, chemists also became interested in this peculiar topology
because theoretical calculations had predicted properties, which would violate one of the most important laws of chemistry concerning the stability of molecules.
Naumov and Hemley's study also indicates that hydrogen initially becomes a dark poorly conducting metal like graphite instead of a conventional shiny metal and a good conductor, as was originally suggested in
theoretical calculations going back to the 1930's using early quantum mechanical models for solids.
To further that goal, Misak Sargsian, a lead coauthor and professor at Florida International University, said he's extending this work into his
own theoretical calculations of neutron stars.
This research conducted a enormous survey of gravitationally lensed quasars and adopted much more
sophisticated theoretical calculations to build a very convincing case for the accelerated cosmic expansion.»
He was awarded a National Science Foundation (NSF) Central Europe Summer Research Institute fellowship in 2006 to
study theoretical calculations with Professor Vlasta Bonacic - Koutecky at the Humboldt University in Berlin, Germany.
«We used much higher -
level theoretical calculations to look deeper than the level of the atom to understand the response and role of the electrons.»
«Our measurements did not support the conventional electron - phonon mediated superconductivity,» McQueeney said, adding that
theoretical calculations matched up fairly well with measurements obtained with ARCS.
Your post here refines this answer with
theoretical calculations sowing that — even with optimistic considerations on the radiative and spatial properties of a» natural» surface temperature change — the fraction of temperature change resulting from natural variability can not exceed ~ 25 % in order to remain consistent with the observed positive sign of ocean heat content change (only the sign, no even the absolute value).
