A new achievements in hydrogensource

The work is devoted to a new class hydro sensor sensors based on sorbitol hydro sensor cables (SGK), which allows to implement 3D spatial-time monitoring of water leaks and breakthroughs pair. The design of stable gas condensate and experimental data, demonstrating its ability to respond not only to traditional water bays, and the appearance near the surface of droplets, the condensate, moisture – the first harbingers of emergencies. The possibility of building on the basis of SGC is highly sensitive systems for the early detection of water leaks and blowouts and a couple other conductive liquids.

Keywords: sorption hydro sensor cable, detection of water leaks, detection of water vapour breakthrough.

Simulation models traffic column robotic vehicles extreme and nonstationary environ

The article is devoted to the development of smart technologies used for the automatic movement of the column of unmanned trucks (avtorobotov) for leading, controlled by the driver of the vehicle.
When developing a robotic control system must convoys represent avtorobotov movement process in the column as if they actually moved under control of the system. One approach that can cope with this task – a simulation used in the article to describe the motion of robotic convoys processes in extreme environments and unsteady.
The article presents the results on the development of the functions and structure of the simulation model of the robotic movement of the column of vehicles in extreme environments and unsteady.
The tasks and requirements defined for the input parameters of the simulation model.
Powered research approaches to the construction of a simulation model. Selected agent-based approach.
Grounded types of agents to process control commands avtorobotov and decision management solutions for the entire convoy using intelligent methods based on agent-based reporting on the situations set parameters.

Keywords: avtorobot, robotised column agent-based approach, simulation, extreme environment.

Dielectric studies of the structure of composite materials on the basis of liquid crystals

The results of dielectric investigation allows to get information about the phase transition temperature of liquid crystals and their orientation structures inside the pores. Currently the most interesting point is obtaining information about the structure of liquid crystals in porous films depends on pores radius. Previously it was noted that orientational structures of LC depends on pore radius. Hence, researches of porous dielectric membranes with pore radius from 50 to 500 nm were conducted where a different orientation of the liquid crystal structure may be seen. The developed model allows us to estimate the angle of liquid crystal molecules in relation to the pore walls.

Keywords: liquid crystal, dielectric measurements, porous film, PET, orientation LCD structure.
