Allocation of object borders is the one of the most important tasks at pavement damages recognition. They contain exhaustive information on it's form, for the subsequent analysis. The method of binarization of the initial image copes with this task. But this process is characterized by existence of a large number of distortions: washing out, gaps and loss of objects integrity, emergence of noise in homogeneous areas. Demand of the mistakes elimination has led to emergence of a large count of binarization methods. The choice of a binarization method and search of the optimum (for some set of parameters) algorithm influences the algorithms applied further to the image analysis. In this article we consider the most popular and modern binarization methods concerning problems of recognition of pavement damages.

In this paper two implementations of the ring amplifier for the low-power ADCs are discussed. Requirements for the DC gain of the operational amplifier depend on the resolution of the ADCs are determined. Estimated power consumption and main characteristics of the proposed ring amplifiers are evaluated. Schematic and topology of both self-biased and latch-based ring-amplifiers are presented.

In the work, the study of dynamics of single molecules by means of total internal reflection fluorescence microscopy is suggested. The fluorescence microscopy is directed to detect the single molecules in different fluids. We developed a new experimental scheme of fluorescence microscopy. The developed system based on total internal regime allows studying movements of single chlorophyll particles in the aquatic environment and opens a great prospect for single molecules investigation.

A new BiJFet array chip (AC) MH2XA030 designed to accelerate the creation of analog integrated circuits (ICs) that retain their performance under the influence of penetrating radiation (the flux of neutrons and fast electrons, the accumulated dose of radiation, the single effects from heavy charged particles) and extremely low temperatures (up to −197°C) is considered. The topology of the array chip and its macro cell is described. The schematic design features of radiation-hardened and cryogenic analog ICs based on the AC are indicated. The circuit simulation results of the main analog components of the AC - voltage comparator, two operational amplifiers and two differential difference operational amplifiers are given.

To measure the active power in a given frequency band, a method based on low-pass filtration of the instantaneous power signal can be applied. For active power digital meters, the low-pass filter is implemented digitally. At the same time, infinite impulse response (IIR) digital filters, finite impulse response (FIR) digital filters can be used to perform low-frequency filtering. The article shows that the parameters of the applied digital filter are significantly affected to the measurement error. The application of cascaded integrator-comb (CIC) filters plays an important role. The article shows that when using a complex circuit containing a CIC-filter and a IIR-filter, the smallest measurement error (among the considered digital filters) is shown. Analytical expressions are obtained, which allows to contact the measurement error of active power and the parameters of the applied digital filter. To verify the reliability of the obtained analytical expressions, simulations were performed in the Simulink software package.

The surface properties of Eu(III)-activated yttrium vanadate, yttrium phosphate and mixed yttrium vanadate-phosphate phosphors with different europium content synthesized via self-propagating high temperature synthesis are studied by low temperature nitrogen adsorption, scanning electron microscopy, aqueous slurry pH measurements and adsorption of acid-base indicators. Among the materials synthesized under similar conditions, phosphate based phosphors possess with a significantly more acidic surface (due to the presence of Lewis acidic centers probably corresponding to phosphorous atoms) and coarse dispersity compared with vanadate analogs, while mixed vanadate-phosphate compounds feature with the most fine dispersity.

In this work an improved mathematical model for a metal ablation by femtosecond laser pulses is proposed. This model is constructed relying on two-temperature hydrodynamic model for electrons and ions and wide-range equation of state for metals. Results of the simulation for several metals are compared with experimental data at different laser fluence and duration of pulses for ablation depth. A good agreement with them and the experiment is received.
