When combined with robust electronic structure methods, such as the equation-of-motion coupled-cluster approach, these techniques enable first-principle description of electronic resonances.
QCD is a highly non-linear theory, giving a first principles description of the strong interactions between quarks and many of the consequences of this theory are only available through large scale simulations.
Table 1 Inventive principles in terms of the first coupling Inventive principles Description of inventive principles 1. Cheap short-living Replace an expensive object with a multitude of inexpensive objects, compromising certain qualities 2. The other way around Invert the action used to solve a problem.
The tests are performed both on one dimensional models of atomic chains, and on first-principles descriptions of molecules.
In 'Abd al-Latif's opinion, the medicine of his age must rediscover and apply Greek medicine with its principles, descriptions of diseases, and therapies.
Mathematical models of such catalytic systems involve in principle the description of coupled reaction/diffusion processes in both SCR and PGM catalytic layers, resulting in computationally demanding modeling tools.
In his talk, "Places for Learning: New Functions and New Forms," he illustrated each principle by description and contrast, showing historic slides of classrooms at MIT and elsewhere to emphasize how ideas about education and learning spaces have evolved in the past century.
As for the organization of this review paper, each imaging technique is profiled with its respective underlying principle, a description of selected current applications, and a discussion of advantages and known limitations.
The paper covers main design principles and description of optimization algorithms for cutting steel at continuous casting plant.
The pertinence and validity of the entered data is governed by the general theoretical principles for description.
