  • Diphenyl-2,2',4,4'-tetraamine molecular structure and its thin film pyroelectric properties

    The quantum and chemical simulation (HF/MP2, cc-pVDZ basis) of diphenyl-2,2',4,4'-tetraamine (DPTA) molecule properties allows to determine the its thin film pyroelectric properties since hydrogen bonds between molecules in the film are weaker than intramolecular bonds. The study of a DPTA photosensitive pyroelectric film microstructure enables one to assume that the dipole moment of the needle-shaped crystallines densely stacked and extended along a film surface is aligned perpendicularly to the surface. The possibility of the reproduced control for DPTA properties may be used when producing the most effective pyroelectric film for photodetectors in infrared wavelength range.

  • To the theory of dispensing of seeds the pneumatic sowing apparatus of an overpressure

    The basic virtue of the sowing apparatus of an overpressure is possibility of conducting of sowing on the big speeds and with high uniformity of dispensing of seeds. But the processes occurring in the sowing apparatus of an overpressure at dispensing of seeds, are insufficiently studied. In the article one of stages of process of dispensing by the overpressure sowing apparatus - transportation of a unit seed by dosing elements of a seed disc is observed. The forces acting on a seed in the course of transportation with a dosing element of a seed disc are defined. The gravity, centrifugal force, force of air drag and pressure force of air refers to to them. The scheme of forces is presented. As a consequence of theoretical research dependence of magnitude of an overpressure in the seed vessel from key parameters of work of the sowing apparatus of an overpressure has been defined. Graphs of theoretical dependence of pressure in the seed vessel from diameter of holes and a seed disc angle of rotation are built. The analysis of the gained results allows to draw following conclusions. The increase in diameter of holes of dosing elements of a seed disc leads to considerable decrease of the pressure necessary for transportation of a seed. At increase in an angular velocity of a seed disc pressure necessary for the secured transportation of a seed is augmented. The increase in an angle of rotation of a seed disc puts insignificant agency on pressure in the apparatus seed vessel.

  • «Relative orientation of the aerial views with the new combination of the corner piece within the stereo mate»

    Relative orientation of the aerial views is the fundamental task of the photogrammetry. The final results depends on the accuracy and reliability of its solving, characterizing the spatial position of the photographed object (area).
    Two groups of the elements of the relative orientation found their industrial application in our country (then ERO). However they don’t use up all the possible combinations of the corner pieces res ipsa loquitur and also between the photogrammes. Moreover it is known that in both systems of the relative orientation of the aerial views (base and linear-angular) visible correlation of the mistakes of the ERO are found, which leads to the additional of the route trough model within the coordinate space XY and XZ.
    One of the possible alternative variants of the application within the group ERO of another corner piece is examined in this article. Five elements of the relative orientation of the aerial views are presented on the left view of the stereo mate as two angles: transverse inclination angle ω1 and longitudinal slope α1, and two angles (α1 and χ2) on the right and the azimuth of the direction of the basis of the design τ. Such a diviosn of the ERO has reduced much the correlation between the mistakes of the angle elements. However other variants are possible (e.g., τ, υ, χ1, α2 and ω2).
    To calculate the photogrammetry co-ordinates of the general formula of the straight photogrammetry mark is proposed, which can be used both for the aerial shots in any direction and for the shooting from the points of the earth surface.

  • Methods of multirate signal processing in distributed sensor networks

    A problem of signal estimation (or estimation of some parameters of the signal) based on measurement results obtained by means of distributed sensor network is considered. The system formed by spaced sensors called nodes (or motes) obtains information about a stochastic process. It is supposed that there is a single source of the information and the distortions are linear.
    Every node gets incomplete and distorted knowledge about the observed process and operates on the low sampling rate. Combined processing of the information obtained from the different sensors makes possible to perform the integrated estimation which is usually much more accurate.
    The application of the information performance criterion provides high robustness in the presence of the noise and the measurement uncertainty and, theoretically, gives the most complete information, while the measurements have severe constraints.
    Due to the multirate signal processing it is possible to decrease requirements on sensor’s sampling frequencies, to reduce the channel loading and the current consumption of sensors. Furthermore, the computational load falls in real-time applications.
