ЭКОЛОГИЧЕСКОЕ СОСТОЯНИЕ ВОДНОЙ И ВОЗДУШНОЙ СРЕДЫ ГОРОДА САМАРКАНДА
Get PDFAn analysis of the dynamics of air pollution in the city in recent years shows that the content of ammonia and formaldehyde in the air tends to remain unchanged. Samarkand belongs to the category of cities with a predominant contribution of vehicle emissions into the atmosphere. Which currently accounts for about 90% of all emissions. The imperfection of the city\u27s transport network and the high level of motorization lead to significant congestion of transport routes and pollution of the adjacent territories

Solving the problem of stationary heat distribution in a complex cylindrical structure by the finite element method: Solving the problem of stationary heat distribution in a complex cylindrical structure by the finite element method
No full textThe distribution of the temperature field of elements of three-dimensional structures is examined in the article and the effect of non-homogeneities on the temperature field in three-dimensional axisymmetric structures is studied. Based on the variational statement of the problem, a finite elementmodel for solving axisymmetric problems of heat distribution in three-dimensional bodies was built basedon the finite element method (FEM); a computational algorithm of the solution and the software wereimplemented
