Downstream (metaphoric) Occurring later than something else; (also, usually, especially) influenced by something else; being a consequence of something else. Input validation is downstream of input entry in the runtime process. Upstream In a direction against the flow of a current or stream of ...

In this paper we investigate the TCP upstream/downstream unfairness issue over the 802.11 wireless LAN with per-flow queueing employed at the access point. The interactions between 802.11 MAC protocol and TCP are evaluated through analysis and simulation. Based on the derived analytical model, an ...

“Downstream” in a supply chain refers to activities post-manufacturing associated with distributing the product to the final customer. In many ways, Upstream is the “supply” and Downstream is related to “demand,” and supply chain managers are responsible for coordinating and managing both ...
Nine exhaust fans (1.22 or 1.32 m diameter) in laying hen and turkey houses were tested with the FANS device placed upstream and downstream for a building static pressure range of 10 to 40 Pa. The results revealed that downstream placement of the FANS device yielded 0.6% 卤 0.4% to 4.0%...
Five upstream steps and four downstream steps with different curvature radii were studied. The curvature radii of these steps of R = 1.64D, 2D, 3D, 4D, and 5D were used. The film cooling effectiveness (η) of these steps was investigated and compared with experiment. The near-field flow ...
However, the fact is that head loss and flow in the upstream system do affect the performance of the downstream system. Over the years, engineers have evolved approaches to deal with the complexities of connecting two systems. There is no single “best way” to simplify the...
