P. 215-218.
Kofanov Y. N., Sotnikova S.
Virtual simulation method is developed in the work. It based on virtual 3D-models of the structures of on-board electronic means designs with superimposed heterogeneous fields of electrical, thermal, mechanical and other processes caused by united impacts of external factors. A distinctive feature of this method is the account of the close relationship of the flowing physical processes between themselves during the simulation.

One-state and two-state lasing is investigated experimentally and through numerical simulation
as a function of temperature in microdisk lasers with Stranski–Krastanow InAs/InGaAs/GaAs
quantum dots. Near room temperature, the temperature-induced increment of the ground-state
threshold current density is relatively weak and can be described by a characteristic temperature
of about 150 K. At elevated temperatures, a faster (super-exponential) increase in ...

This paper is an analysis of lexical categorisation of the temperature domain in modern Eastern Armenian. Compared to the vast research outline proposed in (Koptjevskaja-Tamm 2011), this paper has several important limitations. First, it is focused on non-derived, primary temperature terms (most of which happen to be adjectives or nouns, or both). Derived lexical items, ...

Estimating how uncertain an AI system is in its predictions is important to improve the safety of such systems. Uncertainty in predictive can result from uncertainty in model parameters, irreducible \emph{data uncertainty} and uncertainty due to distributional mismatch between the test and training data distributions.
