The paper presents a method of synthesis of manipulation robot motion trajectory according to mobility degrees. The configuration of the manipulator parts and obstacles are approximated by semiinfinite spaces limited by planes. The fact of robot collision with obstacles is reduced to the problem of determining the compatibility of systems of linear inequalities. The authors developed an algorithm...
In the paper the two-dimensional numerical modelling of heat transfer in crystalline solids is considered. In the mathematical description the relaxation time and the boundary conditions are given as interval numbers. The problem formulated has been solved by means of the interval lattice Boltzmann method using the rules of directed interval arithmetic.
The article constitutes an introduction to IPv6 protocol and is a review of the existing approaches to ensure the coexistence of IPv6 and IPv4, on the example of homogeneous Cisco network infrastructure. In the first paragraph, the IPv6 protocol has been characterized and compared to the IPv4. Then, concepts connected with IPv6 addressing have been described. As the main part, it has been discussed...
In the following work the authors implement mathematical representation of a control system of complex dynamic system. An example of such system is a group of unmanned aerial vehicles.
