In approaches to quantum gravity, where smooth spacetime is an emergent approximation of a discrete Planckian fundamental structure, any effective field theoretical description would miss part the degrees freedom and thus break unitarity. This applicable also trivial gravitational (low energy) idealizations realized by use Minkowski background geometry which, as with other geometry, corresponds...

The transmission of binary information using chaotic switching, also called chaos shift keying i s used. On the receiver side the information i s extracted using a method that is not based on synchronization, but that directly tries to detect which chaotic system of the two can have produced the received signal, provided the channel noise i s bounded by a known value. The results obtained are n...

The results of a long-term research on the variety study 70 pear varieties from genetic collection State Scientific Institution NCFSCHVW summer, autumn and winter ripening periods, grown in south Russia, are presented. Winter-hardy, late-flowering have been identified, which make it possible to reduce crop losses frosts late spring frosts. Highlighted pears with high yield, valuable for commerc...

in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic f...

Abstract Field Programmable Gate Arrays (FPGAs) have become a widely available computational resource for real-time image processing and can be used in time-critical optical process measurements. In this study, we investigate the applicability of spatial filtering technique time-resolved velocity field determination, on example simple water tunnel flow. For this, was implemented custom FPGA pla...
