Stack-based languages (e.g. Forth (Moore 1974), Postscript (Inc. 1999)) have been around for nearly four decades. They are particularly popular today for use as intermediate languages (e.g. CIL (ECMA 2002), JVML (Lindholm and Yellin 1999), (Morrisett et al. 1998)). This is for several reasons: they have good run-time performance characteristics, they resemble the machine level instructions on m...

Incremental stack-copying was used to implement OR-parallel Prolog efficiently in the MUSE system. The idea of incremental stack-copying is to only copy the difference between the WAM data areas of two processors, instead of copying them entirely. In order to further reduce the communication during stack-copying and make its implementation efficient on distributed memory machines, a new techniq...

We introduce and investigate input-driven stack automata, which are a generalization of input-driven pushdown automata that recently became popular under the name visibly pushdown automata. Basically, the idea is that the input letters uniquely determine the operations on the pushdown store. This can nicely be generalized to stack automata by further types of input letters which are responsible...

In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...

results in terms of radon and thoron emissions, travertine and plaster were found to be the most appropriate and inappropriate covering for walls, respectively. furthermore, granite and travertine were discovered to be inappropriate materials for flooring, while plastic floor covering was found suitable. natural ventilation performed better for radon, while artificial ventilation worked better ...

SUMMARY This paper presents a method for comparing and detecting clones of Java programs by analyzing program stack flows. A stack flow denotes an operational behavior of a program by describing individual instructions and stack movements for performing specific operations. We analyze stack flows by simulating the operand stack movements during execution of a Java program. Two programs for dete...

administration of endotracheal surfactant is potentially the main treatment for neonates suffering from rds (respiratory distress syndrome), which is followed by mechanical ventilation. late and severe complications may develop as a consequence of using mechanical ventilation. in this study, conventional methods for treatment of rds are compared with surfactant administration, use of mechanical...
