Investigation of purge time in cathodic dead-end mode PEMFC
Recently, special type of fuel cells has been developed that operates in a Dead End mode. Working in this condition, the Dead-End fuel cell is supplied withhydrogen almost at the same rate of consumption. It is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.Water accumulation that is directly proportional to the cell current is of a grea...
متن کاملDead-End Driven Learning
The paper evaluates the e ectiveness of learning for speeding up the solution of constraint satisfaction problems. It extends previous work (Dechter 1990) by introducing a new and powerful variant of learning and by presenting an extensive empirical study on much larger and more di cult problem instances. Our results show that learning can speed up backjumping when using either a xed or dynamic...
متن کاملA Dead End for MicroRNAs
Dead end (Dnd1) is an RNA-binding protein that mediates germ-cell viability and suppresses the formation of germ-cell tumors. Kedde et al. (2007) now provide evidence that Dnd1 mediates these effects by counteracting microRNA-mediated silencing of mRNAs.

متن کاملDead-End Elimination for Weighted CSP
Soft neighborhood substitutability (SNS) is a powerful technique to automatically detect and prune dominated solutions in combinatorial optimization. Recently, it has been shown in [26] that enforcing partial SNS (PSNS) during search can be worthwhile in the context of Weighted Constraint Satisfaction Problems (WCSP). However, for some problems, especially with large domains, PSNS is still too ...
