The park is located in the scientific campus of the Siberian Branch of the Academy of Sciences in Irkutsk. The territory has the properties of a landscape park. At the same time, it is actively used as a walking area and for sports activities. There are risks of using the land for housing construction because the park is surrounded by intensive urban development. The research proves its recreational and architectural landscape value. The basis of the spatial structure is the particular combination of glades and forest plantations of the park. The system of footpaths, which took shape over 60 years, is a picturesque network that at first glance seems random. The study of the territory allows to identify patterns in the organization of the network. A highway dissects the forest area. A bicycle bridge is proposed in the project for crossing the road by pedestrians and cyclists. The design and architectural form of the bridge minimize the impact on the landscape of this structure. The bridge is designed as two spirals suspended from two high masts. Its length of 210 m, it covers an area with a radius of less than 20 meters. The microrelief on the hillside, represented by micro-watersheds and hollows, makes it possible to differentiate new plantings in the park according to the landscape properties due to this microrelief.","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.

It allows distributing traction forces without changing the trajectory and velocity of the system. In this way, it is possible to define additional traffic quality criteria which the traction control system should strive to achieve. In addition, efficient distribution will allow the robots to move without wheel slip at a higher speed than classical control methods. Robots and cargo combined into one system mechanically and informationally, form a variable configuration transport cell (VCTC). The following transportation quality criteria are considered: no wheel slippage, maintaining a given speed, no soft bumps, minimizing work in the generator mode, maintaining the desired final charge levels of the robot batteries after transportation. The proposed methods for the efficient distribution of traction forces are based on the finding local minimum and on the Hebbian learning principle. Tests are carried out in the Simulink using the dynamic mathematical model of the VCTC. In the case under consideration, new distribution methods made it possible to increase the maximum allowable turn entry speed by 27% compared with classical control approaches. At a lower speed new method of distribution showed good results on additional transportation quality criteria. The presented material can also be used for multi-wheeled robots with steerable drive wheels.","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.

Defects in flat rolled roofs, as well as defects in building structures in general, are in close organizational and technological relationship, in which the life cycle of an individual defect can be a synergistic multiplication or subtraction in defects life cycle parameters. \u0000The key flaw of modern methods for assessing physical deterioration are the initial and predominantly manual instrumental studies, in connection with which the methods are overly simplified, templated, subjective in natural assessment of life cycle resource intensity.

In preparation for the simulation, the original solid model is idealized by removing small chamfers, fillets, and small diameter holes. Movable joints with linear rolling guides and ball bearings are replaced by rigid joints, since vibration damping in these units is not considered. During the first simulation, ten natural frequencies with the largest values of the oscillation amplitude are obtained. The second simulation shows, the influence of the spindle drive layout (coaxial installation of the electric motor with the spindle through a cam clutch or connection using a toothed belt transmission) and additional devices for dissipating vibration energy (mass and structural dampers in the form of structural elements articulated through plastic bushings) is revealed by the magnitude of forced steady-state oscillations that may occur during the processing of the part.","PeriodicalId":9367,"journal":{"name":"Bulletin of Belgorod State Technological University named after.
