AbstractWe consider some general aspects of dependence of magneto-conductivity on a magnetic field in metals having complicated Fermi surfaces. As it is well known, a nontrivial behavior of conductivity in metals in strong magnetic fields is connected usually with appearance of non-closed quasiclassical electron trajectories on the Fermi surface in...

We consider the problem of exact experimental determination of the boundaries of Stability Zones for magneto-conductivity in normal metals in the space of directions of magnetic field B. As can be shown, this problem turns out to be nontrivial since the exact boundaries of Stability Zones are in fact unobservable in direct measurements of conductiv...

AbstractThermofrictional cutting with pulsed cooling is investigated by the finite-element method, using Deform 3D Machining software. On that basis, the cutting mechanism proposed earlier is confirmed.

AbstractA design procedure for nonstationary production systems is outlined. On the basis of the generalized mathematical model, specific models for components of nonstationary systems are developed. In particular, a model for slipway finishing of a part prior to welding in submarine hulls is proposed.

Abstract We consider the dimer model on a hexagonal lattice. This model can be represented as a “pile of cubes in a box.” The energy of a configuration is given by the volume of the pile. The partition function is computed by the classical MacMahon formula or as the determinant of the Kasteleyn matrix. We use the MacMahon formula to derive the scal...

AbstractModels based on regression analysis for predicting the operational efficiency of high-pressure roller crushers are considered. A systematized and structured production database is created and statistically analyzed. The consistency of the data is verified. The parameters with the greatest influence on the productivity are identified. The ba...
