The metrological possibilities of the Kinect controller for direct measurement of objects are considered in this review. The principal components of the controller, the principle of its operation and the main technologies compiling Kinect are considered.
The article is devoted to the analysis of errors matrix balun. The method of indirect measurements by used for determine the error matrix transformation and an analytical dependence of the standard deviation of the technological parameters of such a device was obtained, which can easily be used in different CAD systems.
The article deals with the issues of processing of results of activity of educational institutions in relation to FSAI FPE “Academy of standardization, metrology and certification (educational)” the Novosibirsk branch.
This paper seeks an analysis of high-precisions standards of the microwave used by calibration of meters parameters transfer in coaxial paths, and methods for their calibration.
From the very beginning of commissioning of fiber-optical cables of scientists in the field of optics and communication the question began to excite: “Whether this new environment of signaling is ideal? What external factors influence for this environment, by what laws they are described?” Now many factors of influence of environment on a fiber-optical cable are studied. Nevertheless, researches in...
A brief literature review of the foundations of the theory of dielectrophoresis and electrorotation of a cell in an electric field, and the extent of their practical application in the field of medicine, microbiology, virology, biophysics are provided. Primary concerns of metrological provision of traceability of measurements in the field of dielectrophoresis and rotation of the cell as per Federal...
In the article the collective name «theory just as the theory of scalar elds of dynamical systems or the problem of adaptive control by initial state replaced» by a more informative (in the title of the article). New concepts of dynamical systems theory (scalar field, the center offset of the scalar field) to a single unified space of dimension (3n+2), where 1) n+1 - dimensionality of the state space;...
The error of positioning in the angular direction is rather specific and typical only for laser pattern generators with a circular scanning containing a mechatronic rotation unit with a built in angle encoder. The error of this encoder is particularly important for formation of topology of angle measuring structures, such as angular rasters, limbs, scales, or multibit code disks, and for synthesis...
It is offers to use the sorption-capacitance method to measure the humidity of benzene. It also gives the description of the most widespread method of measurement of humidity of organic liquids by K. Fisher, and points out its peculiarities of use that re-strict its universal application. The research was carried out by sorption-capacitive sensors of Honeywell. These sensors nowadays are used to measure...
When transmitting information and control signals to electrical, electromechanical and mechatronic systems are require reduction to the lowest possible levels of noise interference. For this is substantiated in the general formulation of the one-dimensional problem of determining the sensitivity of a linear stationary optimal Wiener filtration. It is proposed to use the method of local approximation...
Progress in the advanced branches of technology has caused the need to manufacture parts of highly complex shapes that are often found through experimenting and only later is described with mathematical models. Most coordinate-measuring machines (CMM) now available have their capability based on implementation of the Cartesian coordinate system. This feature has become a bottleneck on the way to creating...
This paper describes measuring converters with frequency output signal for cryogenic temperature based on electron-hole plasma absolute helical instability of specimen placed in longitudinal electric and magnetic fields. Sensitivity of strength measuring converters reached 15 kHz/N at temperature 77K. Sensitivity of angular displacement measuring converters reached 50 kHz/deg. The experimental results...
The article gives the circuit design results of the of radia-tion-hardened charge-sensitive amplifier (CSA) MH2XA010-04, intended for the capacitance sensor signal processing. The main equations for optimal design of CSA are given, taking into account a new circuit (2016) of structured array MH2XA010. The variants of construction of multichannel CSAs for the tasks of tool engineering based on the...
An improved estimation method of electrochemical impedance equivalent circuits' parameters is proposed. The method allows to decrease estimation errors of an electrolyte resistance in up to 6.5 times, a double layer capacitance - up to 5.8 times, and a charge transfer resistance - up to twice. The accuracy of Warburg constant estimation remains unchanged. To obtain electrolyte resistance estimation,...
The quantitative control of dissolved humidity in organic liquids is the most important task. The most common method for testing dissolved humidity is the method of K. Fischer. But, this method has a number of peculiarities that prevent its widespread use. The authors of this article propose the number of features to measure the humidity of organic liquids. They are: 1) the sorption-frequency method...
In article features of an assessment of legibility of the speech when using formant approach are considered, in particular, influence of effect of forcing of the speech on a range a formant is considered. Earlier the assumption that a range the formant at forcing changes also as well as a speech range has been made. As a result of researches influence of effect of forcing on a range a formant has...
A method for simulation of classic substitution ciphers for the purpose of their study in the learning process is considered. The method is based on the decomposition of the alphabets of the plain and encrypted texts. Implementation of the method has a two-level structure: the basic components are implemented using software, variation is part of the settlement. This allows user to simulate a wide...
this paper proposes a method of reconstruction of digital holograms with small angles between the interfering wave fields. The proposed approach is based on a combination of methods of digital holography and step-by-step method of phase shifts and allows to obtain not only the amplitude but also the phase information of the measured object.
We consider the theoretical background to the justification of new approaches to obtaining and analysis, interferograms. The proposed approach is based on a combination of methods for the analysis of interferograms obtained by the intensity change of the interfering beams and the phase shift.
