Statistical link between the structure of molecular clouds and their density distribution
Sava Donkov, Todor V. Veltchev, Ralf S. Klessen
We introduce the concept of a class of equivalence of molecular clouds represented by an abstract spherically symmetric, isotropic object. This object is described by use of abstra…
Adiabatic Interactions of Manakov Solitons -- Effects of Cross-modulation
V. S. Gerdjikov, M. D. Todorov, A. V. Kyuldjiev
We investigate the asymptotic behavior of the Manakov soliton trains perturbed by cross-modulation in the adiabatic approximation. The multisoliton interactions in the adiabatic ap…
Line shapes and time dynamics of the Förster resonances between two Rydberg atoms in a time-varying electric field
E. A. Yakshina, D. B. Tretyakov, I. I. Beterov +7
The observation of the Stark-tuned Förster resonances between Rydberg atoms excited by narrowband cw laser radiation requires usage of a Stark-switching technique in order to excit…
Stark broadening of B IV spectral lines
Milan S. Dimitrijevic, Magdalena Christova, Zoran Simic +2
Stark broadening parameters for 157 multiplets of helium like boron (B IV) have been calculated using the impact semiclassical perturbation formalism. Obtained results have been us…
Modelling the structure of molecular clouds: I. A multi-scale energy equipartition
Todor V. Veltchev, Sava Donkov, Ralf S. Klessen
We present a model for describing the general structure of molecular clouds (MCs) at early evolutionary stages in terms of their mass-size relationship. Sizes are defined through t…
Power, Delay and Area Comparisons of Majority Voters relevant to TMR Architectures
P Balasubramanian, N E Mastorakis
N-modular redundancy (NMR) is commonly used to enhance the fault tolerance of a circuit/system, when subject to a fault-inducing environment such as in space or military systems, w…
