The wireless sensor network with rectangular grating structure with from 20 to 260 numbers of clusters of smart sensors has been studied. The probability of non-failure operation, a cycle of survey duration have been estimated.
Approach to processing the output information of a spectrometer on diamond detectors used on board the space apparatus is considered. The spectrometer on diamond detectors forms 24 output signals containing integrated quantitative characteristics of the streams of space radiation in the environment (electrons, protons and the heavy charged particles) in the power range from 0 to 10000 MeV. The mathematical apparatus allowing to receive differentiable information on a stream of electrons, on a stream of protons and on a stream heavy charged particles stream in the 21 power range is offered.
Demonstrated singleton UV photodetector based on diamond, which is used in spectrophotometric equipment. This photodetector has spectral photosensitivity characteristic depending on the magnitude of the applied bias voltage. Presents the spectral characteristics of photosensitivity of the photodetector obtained experimentally. The possibility of using such photodetectors for systems analysis of the composition of multi-component mixtures and the use of photodetectors in spectrometry.
The elements and structure of a distributed wireless monitoring system to detect gas leaks in real time, providing safe and reliable operation of the gas transmission network.
The results of development experimental sample of mesure with relief elements size less than 100 nm for calibration of optical, near-field and electron microscopy are presented.
The transformer analog-digital converter of temporal type angular displacements without the stage of displacement phase conversion and with the direct transformation of displacement to temporal interval and then to digital code is developed. The device functional scheme and mathematical description are considered, the maximal relative error is estimated.
А connection between the State metrology and economics is considered. The existence of direct relation between the level of metrology development and the competitiveness of goods and services in the global market is shown. Various sections of the uniformity of measurements assurance should be effectively supported by the State to allow the development of science intensive technologies and the manufacturing of high-tech products. On the base of analysis of the leading foreign and national metrological institutes activity, of the published results of various research works, of scientific analyses and annual reports the authors prove that economic success depends, inter alia, on the ability to produce and sell precisely measured and reliably tested products and services where the metrology plays a central role for manufacturers, suppliers and consumers.
The problems of creation of a low intensity optical radiation signal standard sources based on the nanosized apertures and semiconductor quantum dots are considered. The use of technology of the focused ionic beam technology for isolation of a single quantum dot is offered suggested.
