چکیده
A ow-directed inlining strategy uses information derived from control-ow analysis to specialize and inline procedures for functional and object-oriented languages. Since it uses control-ow analysis to identify candidate call sites, ow-directed inlining can inline procedures whose relationships to their call sites are not apparent. For instance, procedures deened in other modules, passed as arguments, returned as values, or extracted from data structures can all be inlined. Flow-directed inlining specializes procedures for particular call sites, and can selectively inline a particular procedure at some call sites but not at others. Finally, ow-directed inlining encourages modular implementations: control-ow analysis, inlining, and post-inlining optimizations are all orthogonal components. Results from a prototype implementation indicate that this strategy eeectively reduces procedure call overhead and leads to signiicant reduction in execution time.

Constriction Scour In Pressurized Flow Condition (RESEARCH NOTE)
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...

Bottom intake is an intake structure which can be considered as an alternative for regular intakes in mountain streams Water in in taking from river are very vast and complicated issues, each project has special characteristics which should be considered. Water intake from riveris generally based on Pump and gravity method. The gravity method is more useful and common because of continuity and ...
متن کاملDirected and Almost-Directed Flow Loops in Real Networks
Directed flow loops are highly undesirable because they are associated with wastage of energy for maintaining them and entail big losses to the world economy. It is shown that directed flow loops may appear in networks even if the dispatched commodity does not physically travel along a closed contour. Consequently, a theorem giving the necessary and sufficient condition of a directed flow loop ...
متن کاملReducing Directed Max Flow to Undirected Max Flow
In this paper, we show that the directed maximum flow problem can be reduced to the undirected maximum flow problem. Our result yields a new algorithm for finding maximum flows in directed graphs, by reducing any directed maximum flow instance into an undirected maximum flow instance and running the Karger-Levine algorithm to find a maximum flow in the resulting undirected graph. Given a direct...
متن کاملReducing Directed Max Flow to Undirected Max Flow and Bipartite Matching
In this paper, we prove two new results related to finding maximum flows in directed graphs and finding maximum matchings in bipartite graphs. In our first result, we derive a new algorithm for finding maximum flows in directed graphs. Our algorithm works by reducing a maximum flow problem on a directed graph to a maximum flow problem on an undirected graph, and running the Karger-Levine algori...
