The problem of identification of defects in the construction in the form of a wall element is considered. Numerical simulation of the structure is carried out in the Ansys finite element complex. The investigated model of a wall structure has a defect in the form of a through crack, of a certain length. The edges of the cracks do not interact with each other. The excitation of the structure under pulsed loading is considered. Wave field displacements at control points are analyzed. Identified signs of identification of crack-like defect.

In article traffic safety in intensive transport streams on bridge crossings is considered. In a case when the bridge crossing has on one lane in each direction, at repair of a half of width of the carriageway - density of a transport stream sharply increases. The increase in density of a transport stream leads to change of speed of the movement of vehicles and to reduction of minimum safe distance between the cars moving in the passing direction on the bridge crossing during its repair or reconstruction. At the movement of vehicles with minimum safe distance specified in the table the maximum capacity of the bridge crossing at its repair or reconstruction will be provided.

Keywords: traffic safety, bridge crossing, intensity of the movement, repair of the carriageway, minimum safe distance

The investigation provides the complex approach for optical properties study of the cobalt octaephylporphyrin. The complex shows the magnetic moment of the central ions. The strength and sign of anisotropy and optical transparency within the visible range can be changed by variation of an environment of the central metal atom (the ligand field) or its replacement. As a result, these materials can be used as stable qubits and nanoelements for spintronics and quantum computing. It is well-known that devices for spintronics and quantum computing require materials with femtosecond time resolution. The insights into the relations between geometry structure and optical and magnetic properties allow to design the tailor-made materials. In this work, we have investigated the optical properties of the cobalt octaephylporphyrin. We have calculated the theoretical spectra of the extinction coefficient, refraction index, and absorption index. These spectra provide us the additional information about optical transitions within the visible range. The design of the stable nanoelements with femtosecond time resolution is hardly-probable without understanding the nature of processes.
