Controller automata, adopting an unbounded stack, provide sequential execution of a group of timed automata according to various priority policies. When a preemption between two processes is considered, a time lag function is used to transform a timed automaton into one that waits a certain time when preempted by another timed automaton. This paper proposes a static algorithm for timed lag by cloning...
Exchange protocols are an important theoretic basis to make secure electronic commerce and electronic business transactions possible, in which the fairness is a crucial property. To ensure and verify the property, a specific model is proposed, based on the extensive game with imperfect information. Fairness is built in the protocol game and the corresponding game tree. To verify the property, a tree...
Effectiveness forecast of especial vehicle is important in vehicle development and compare research. This paper establishes forecast model of vehicle effectiveness by factors analysis with interpretability, and RBF (radial basis function) neural networks with short training time and precise function. Secondly, the result of forecasted and original is contrasted together, then the quality and creditability...
Interrupts are important aspects of real-time embedded systems to handle events in time. When there exist nested interrupts in a real-time system, and an urgent interrupt is allowed to preempt the current interrupt handling, the design and analysis of the system become difficult due to the lack of appropriate behavioral models. This paper proposes a compositional model for nested interrupts and an...
