The article presents findings of distribution patterns of Russian grammatical categories computed with the help of MyStem.3 tagger and a proprietary Russian language processor, ETAP-3. The corpus of ...over 1.1 mln tokens compiled for the study comprises two types of academic textbooks used in Russian schools: Science and Humanities. We computed descriptive metrics of each textbooks with the help of the text analyzer RusAC (http://tykau.pythonanywhere.com/) and pursued the contrastive analysis of Science and Humanities textbook features. Significant differences of two types of the texts were found in distribution patterns of noun cases and verbs tenses, while morphological categories of nouns, adjectives, verbs, and adverbs demonstrate similarities. The specifics of grammatical patterns defined for classroom textbooks can be used in further studies on distribution of morphological patterns and text complexity of Russian academic texts.
The paper treats a problem of propagation of electromagnetic wave in a plane shielded dielectric waveguide. The waveguide is characterised by an isotropic inhomogeneous permittivity and constant ...permeability. Considered symmetric guided waves are characterized by a pair of (coupled) propagation constants. The physical problem is reduced to an eigenvalue problem for an operator pencil. A discreteness property for the sought eigenvalues is proved.
The architecture of high-performance data storage and processing systems has changed considerably. Modern cloud computing systems are often not just a hybrid but also supports hardware acceleration. ...The paper describes the scope of information security protocols based on PRNG in industrial systems. The work provides a method for implementing GOST R 34.12-2015 Based Pseudo-Random Number Generator in hybrid systems. The description and results of studies parallel CUDA and FPGA versions of the algorithm for use in hybrid data centers are presented.
