This paper describes a method applicable for measuring arrival time (PAT) of the pulse of pulsar radio emission, using a wideband optoelectronic processor (OEP). The OEP includes an acousto-optic spectrum analyzer and a digital signal processor. A distinctive feature of the OE-processor is connected with a special time delay operation mode of the use of a multielement CCD protector and an integration mode. In this mode the OE-processor fulfils dispersion compensation for the radio emission received by the photodetector. In PAT measurement the time delay caused by the signal pass through the CCD photodetector is taken into account. The components of the PAT measuring instrument error are considered. The results of the application of optoelectronic processor in a radio telescope are presented.

Evaluation is made of thermal influence of the electron probe in the low-voltage x-ray nanoanalysis. It is shown that despite significant increase in volumetric power density, due to electron irradiation, for most inorganic materials thermal effects are of no significance. For orogenic materials, these effects can significantly affect the results, causing destruction of a sample.

Method and the experimental setup ITZhM for measurement with high accuracy permeability and barrier properties of the membranes and film materials by determining the kinetics of the change of pressure in the liquid above the membrane were developed.

This paper discusses the implementation of simultaneous localization and mapping algorithms in industrial television system. A description of a probabilistic model of the SLAM task is presented based on the FastSLAM algorithm. The article also discusses the possibility of using the unscented Kalman filter to estimate the movement of spatial landmarks. These points are the key features of the camera images that can be consistently detected and recognized within the video stream. The work contains a general model of camera movement and the method of assessing the pose in a space using a particle filter.

It is shown that as a result of changes in mass and elastic properties of the film based on latex and activated carbon, under the influence of acetone vapor, the resonance frequency of the quartz resonator increases by an order greater than usually in quartz microbalances. It is found that the sensitivity of the same sensors to vapors of water and ethyl alcohol is significantly less than the sensitivity to acetone.
