The problem of rational placement of optoelectronic surveillance system towers has been formulated in the article, efficiency of the existing system of opto-electronic surveillance has been assessed, the approach to rational choosing of the towers location based on cluster analysis has been proposed, the surveillance efficiency increasing when using the proposed approach has been shown.
The study deals with a hardware and software implementation of a system for measurement of complex electric signals by quadrature sampling method with filtering using Altera cyclone III FPGA. Ther FIR filters are computed by weighting method with window functions.
The models of problems of statistical radiophysics concerning optimization of radio networks creation of the State Border Guard Service of Ukraine and methodology of their application option selection at the border protection sector have been proposed. Statistical and probabilistic approaches to accounting of radio propagation peculiarities for the different laws of terrain heights description, the...
Temperature-sensitive thick-film systems based on spinel-type NiMn2O4-CuMn2O4-MnCo2O4 manganites with p-and p+-types of electrical conductivity were obtained. All elements are shown good electrophysical characteristics before and after long-term ageing test at 170 °C. It is shown that in two-layer p-p+ systems are typical increases of electrical resistance during ageing test, while three-layer type...
