The effects of bed-load movement on mean flow characteristics were experimentally investigated using particle image velocimetry (PIV). The gravel beds associated with open-channel flow are hydraulically rough, and two types of grain with different median diameters were used. The flow field and...

This paper aims to contribute to the ongoing research on tree-shaped flow structures. Here, we focuses on porous-walled tree-shaped networks, namely the laminar fluid flow. Analytical models are developed for pressure distribution along the porous tree-network and for the hydraulic resistance...

Constructal theory is invoked to optimize a dendritic path flow structure for minimizing overall flow and thermal resistances. Convective cooling of a ring-shaped body is the aim of this investigation. The construct of flow paths is Y-tree shaped; while the body has heat generation over the area,...

В статье обоснованы актуальность структурной модернизации промышленности на современном этапе ее развития и необходимость усовершенствования для этого...

В данной статье рассматриваются вопросы формирования оптимальной структуры собственных и заемных средств предприятия, направленных на модернизацию основных...

We characterize the optimal structure of prizes in contests, when the contest designer is interested in the maximization of either the expected total e¢çort or the expected highest e¢çort. The all-pay auction framework in the present paper makes it possible to derive all the results in Benny...

The urgency of structural modernization of the industry on the present stage of its development and the need of improvement of the state industrial policy are justified in the paper. Contents of the terms \"industrial structure\", \"optimal structure\", and \"industrial structure\" are...
