In this paper it is shown, that the digital filtration of result of variable-filed Hall measurements by weighting digital-data filter with Blackman window lead to error suppression for densities and mobilities of charge carriers, determined by mobility spectrum analysis with multicarrier fitting. © 2014 IEEE.

In this paper, we report the possibilities to apply photon sieve principle to binary diffractive lens in millimeter wave band. The FDTD simulation showing the idea of the photon sieve application to millimeter wave optics does not allow increasing resolution power, due to the small number of holes in the FZP aperture. But such simulation results may be used in simple computational experiments in millimeter wave which allows obtaining insight into physical systems characterized by nanometric objects because D/f and Dλ are almost the same. © 2010 EMW Publishing.

Contemporary tendencies in developing computing and communication systems are, more than ever, pointing out the necessity of transfer from computer and information systems to the optic and even quantum ones [1–4]. Saturation of microelectronics potencies can be seen in the simple and obvious facts, i.e. slowdown of effectiveness increase rates for the classical Turing computing systems and transfer to multicore parallel computations in electronics, as well as greater attention is paid to the optical communication channels, memory and data transmission systems, which is due to high density of information pack in the optical spectrum of electromagnetic waves [5–7].Taking into account the classical Shannon’s understanding of the information quantity and specific characteristics of an optical communication channel, in this work, we are trying to draw a parallel between the classical communication channel and the quantum one, which enables us, in some simple cases, to consider the approximate dependence of maximum information transmission rate on the key characteristics of laser emitter, including the average transmission power, bandwidth, and polarization. © 2014, Allerton Press, Inc.

In this article described application of holograms of Denisyuk executed in special technology, for advertizing. High advertizing influence is noted at a simultaneous combination of two factors-high diffraction efficiency and taken out before the hologram orthoscopic, or pseudoscopic images. © 2013 Allerton Press, Inc.

Similarity was quantified for the ecosystems of the West Siberian Plain based on the masses of plant cover, dead organic matter, and underground organic matter (including soil humus) and the resultant matrix was subjected to cluster analysis. The results showed that the differentiation in the vegetation was nearly equally attributable to zonal gradients of thermal and moisture conditions (waterlogging), while the differentiation in the underground part of the ecosystems was predominantly under control of waterlogging. Intratypical differences in the underground part were due to zonal-subzonal heterogeneity in the gradients of thermal and moisture conditions, composition of vegetation, and flooding during snow-melt period. Such division did not entirely agree with subzonal division. The ecosystems were rather aggregated on the basis of the three abovementioned characteristics, with flooding and forest-forming species being the same. © 2011 Pleiades Publishing, Ltd.

Similarity coefficients were quantified for the ecosystems of the West Siberian Plain on the basis of the air-dry masses of dominant and subdominant plant species in five life forms (mosses, lichens, grasses, dwarf shrubs, shrubs, and trees) indicated in the formation ranges of the phytogeographic map of the West Siberian Plain. The resultant matrix was studied with cluster analysis and two classifications were made: one averaged over the formation ranges and the other over groups of the formation ranges. Expected informativity of the proposed classifications expressed in explained variance was 11-16% higher than that of the vegetation-based division used in the original phytogeographic map. © 2011 Pleiades Publishing, Ltd.
