Factors Governing the Chemical Stability and NMR Parameters of Uracil Tautomers and Its 5-Halogen Derivatives

open access: yesMolecules, 2020
We report on the density functional theory (DFT) modelling of structural, energetic and NMR parameters of uracil and its derivatives (5-halogenouracil (5XU), X = F, Cl, Br and I) in vacuum and in water using the polarizable continuum model (PCM) and the ...

On physical web models

open access: yes2016 International Siberian Conference on Control and Communications (SIBCON), 2016
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could be implemented with the help of mobile devices.

Models in physics [PDF]

open access: yes, 2018
In its most common use, the term ‘model’ refers to a simplified and stylised version of the so-called target system, the part or aspect of the world that we are interested in. For instance, in order to determine the orbit of a planet moving around the sun we model the planet and the sun as perfect homogenous spheres that gravitationally interact with ...

Application of the material point method in the modeling of arching effects behind retaining walls with active movements [PDF]

open access: yesNumerical Methods in Civil Engineering, 2023
Numerical modeling of problems with large deformations is one of the main challenges in computational mechanics. Conventional numerical approaches cannot accurately model large deformations.
