An analytical solution is obtained for the problem of determining the optimal initial thickness of a spherical member exploited under the conditions of double-sided mechanochemical corrosion. The optimal thickness is meant to provide the required service life of the vessel with a given capacity and the economical consumption of the material. The corrosion rates are supposed to be linearly dependent on maximum stress and exponentially decaying with time.

The multi-impulse and multi-criteria optimal trajectories of the spacecraft transfer between orbits of various types are considered. A practical goal is the inspection or service of a number of space objects moving along these orbits at the initial data set. It is required to define a set of the admissible solutions taking into account priorities and possible restrictions on time or on expenses of energy, and to choose the best of possible routes for successively visiting every object in the desired group.

Network games - is new and important part of modern game theory. Networks illustrate the interaction of both individual players and groups. Pairwise interaction is characterized by the ability of players to interact one by one with neighbors in a network. In the paper the analytic expression for the characteristic function is derived. And for special classes of network games the Shapley value is computed.

Changes in the stress-strain state of the cornea and in the intraocular pressure (IOP) readings obtained by Goldmann (GAT) and Maklakov (MAT) applanation tonometers after hyperopia correction surgery are discussed. Two types of refractive correction procedures (LASIK and IntraLASIK) are considered. In the ANSYS software package the corneasclera elastic system is presented as two conjugate transversely isotropic spherical segments loaded with internal pressure. The cornea is simulated as a multi-layered transversely isotropic elastic shell and the sclera is modelled by a transversely isotropic homogeneous elastic shell. In order to estimate changes of the IOP readings obtained by GAT and MAT after hyperopia surgery the problem of deformation of the cornea under the load with a flat base is considered. The IOP readings before and after the surgeries for two types of tonometers are compared for the same value of true IOP.

Problem of electron beam dynamics simulations for triode type cylindrical source is considered. The source produces intensive radial converging electron flow for irradiation of cylindrical targets. The angular spread of initial electron velocities, controlling grid defocusing effect, ions flow from the target and electron backscattering effect are taken into account.
