This paper studies the differential equation of the second order in the segment [0, π] with varying delays. Construct a characteristic function of the operator generated by this equation and the boundary conditions at the ends of space, studying certain generalization of these operators, which naturally imposed....

Robot manipulators are usually used in many industrial apllications where a number of practical tasks should be executed. The very important part of that execution is interaction between robot and environment. Control of the interaction is crucial for successful execution of industrial processes. Typical applications include deburring, machining, a...

Repairing technologies for pipelines still require attention due to large extent of distribution network containing different construction parts including elbows, branch connections and others. Repairing of the defects in the branch connection area without interruption of the gas supply is very difficult. Such defects mostly require replacing of th...
