The article is dedicated to the elements of Byzantine influence in the Caucasian architectural monuments of 9th–10th c. Its greatest extent shows from the end of 9th c. Abkhazia and Alania, where a local version of the provincial (Pontic) Byzantine architecture was created. In Kakheti several groups of Byzantine master-builders participated in the 10th c. in construction of churches in Vachnadziani, Sanagire, Bodbe etc., and also brought here the tradition of brick architecture. In Klarjeti and Tao the Byzantine builders, who used opus mixtum technique, were involved in different way in the 950-960’s in the construction of the churches in Opiza, Doliskhana, Dört-Kilise, Sinkoti and Ezbeki. Finally, in Armenia Byzantine influence was manifested from the middle of 10th c. in the brick architecture of Vaspurakan.
The book is the collection of papers on history, archaeology and art critics of North-West Russia and Baltic area.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
