This article presents the results of a study technological parameters and material consumption new structures two-layer knitted fabric. To variants fabric on Long Xing 252 SC flat-fanged machine, five were developed, which differed from each other in weave structure.

Purpose is to identify a dependence of basalt raw material fine screening upon the operating and structural parameters sieving equipment. Methods. The research results have been obtained relying comparative analysis In this regard, analyzed grading efficiency characteristics were defined for three densities rock mass mined in open pits. They are γ = 1.4 g/сm3 tuff; 2.2 lava-breccia; 2.6 basalt....

Transformer model; Load flow analysis; Symmetrical components; Distribution systems Abstract This paper presents an efficient approach for developing three-phase transformer admittance matrices in the radial power-flow analysis. The proposed transformer model overcomes the singularity problem of the nodal admittance submatrices of ungrounded transformer configurations. This has been achieved by...

This paper develops a least-squares approach to the solution of the incompressible Navier–Stokes equations in primitive variables. As with our earlier work on Stokes equations, we recast the Navier–Stokes equations as a first-order system by introducing a velocity-flux variable and associated curl and trace equations. We show that a least-squares principle based on L norms applied to this syste...

The Bethe-Brueckner-Goldstone many-body theory of the Nuclear Equation of State is reviewed in some details. In the theory, one performs an expansion in terms of the Brueckner two-body scattering matrix and an ordering of the corresponding many-body diagrams according to the number of their hole-lines. Recent results are reported, both for symmetric and for pure neutron matter, based on realist...
