in this paper, first a sensitivity analysis of parameters affecting the performance of the steam generator is performed. this process includes the pinch temperature difference and the gas velocity (width of the hrsg) as the operating parameter and geometrical parameters (fin’s thickness, fin’s height, number of fins in each inch, tube transverse pitch) for each pressure parts is carried out, an...

This paper is focused on the suitability of selection parameters supporting structure bridge crane for needs cross-section optimization. The cross section beam analysed in terms its rigidity and dimensions with respect to span crane. When optimizing reduce overall weight, recommendations are given address issue cross-sectional stability. An iterative procedure design at specified load capacity ...

Abstract The study substantiates the need to apply methods of economic and mathematical modelling optimization production process enterprises agrarian complex. key elements various stages development construction an model agricultural enterprises’ resources that optimizes resource reserves for identification, judicious use, enhancement activity efficiency are taken into consideration. proposed ...

rainfall-runoff modeling is most important component in the water resource management of river basins. the successful application of a conceptual rainfall-runoff model depends on how well it is calibrated. the degree of difficulty in solving the global optimization method is generally dependent on the dimensionality of the model and certain of the characteristics of object function. the purpose...
