Analysis of energy demandingness of metallurgical production

The article suggests the possibility of using methods of structural analysis to calculate the direct and complex consumption and, on the basis of this calculation, are can determine the energy demandingness of the individual metallurgical technologies

Numerical model of a pine in a wind

summary:Steady-state nonlinear differential equations govering the stem curve of a wind-loaded pine are derived and solved numerically. Comparison is made between the results computed and the data from photographs of a pine stem during strong wind. The pine breaking is solved at the end
