An invisible flow watermarking QIM scheme based on linear error-correcting subcodes for channels with substitution and deletion errors is proposed in this paper. The evaluation of scheme demonstrates similar to known scheme performance but with lower complexity as soon as its implementation is mainly based on linear decoding operations. © IFIP International Federation for Information Processing 2013.

The study of the magnetic properties of glass-covered amorphous microwires is reported. This study is focused on the influence of a high frequency electric current and of temperature upon the surface magnetic domain structure. Investigations are performed using the magneto-optical Kerr effect technique, and it is found that the high frequency current and heating process have a great and essential influence upon the surface magnetization reversal and surface domain structure. The induced formation and transformation of the surface magnetic structure are key processes that determine the stable operation of giant magneto-impedance devices. © 2015 Elsevier B.V.

We consider methods for finding expected incomes in systems of Markov queueing networks with incomes and unreliable servicing systems. We study the cases when incomes from network state transitions are either deterministic functions of state and time or random values with known first two moments. © 2015, Pleiades Publishing, Ltd.

The specifics of photochromic transformations of spirocyclic molecules at the nanostructured metal surface were studied by hyper-Raman spectroscopy (HRS) and spectrophotometry. Unique nanostructured systems were prepared, and their surface morphology and optical properties were examined. Enhancement of the photochromic transformations near the nanostructured metal surface was revealed. HRS spectra for various classes of spirocyclic compounds adsorbed on nanostructured systems of different types (granular silver films, AgCl-Ag films) were measured. The bands due to in-plane vibrations have the highest intensity, thereby indicating preferred planar geometry of adsorption of the test molecules. © Pleiades Publishing, Ltd., 2009. Source

By means of fluorescence spectroscopy, it has been found that the oscillator strength of the electronic transition in CdSe/ZnS nanoparticles increases when the hydrophilic fluorescent CdSe/ZnS nanoparticles form complexes with cationic and anionic polyelectrolytes. However, an increase in the relative quantum yield and photostability is possible only in the complexes of the anionic shell-covered CdSe/ZnS nanoparticles with polycations. The mechanisms of the effect of ionic interactions on the probabilities and channels of electronic transitions in the nanoparticles are discussed. © Pleiades Publishing, Ltd., 2009. Source
