[HTML][HTML] Timed recursive state machines: Expressiveness and complexity

M Benerecetti, A Peron - Theoretical Computer Science, 2016 - Elsevier
The paper proposes a temporal extension of Recursive State Machines (RSMs), called
Timed RSMs (TRSMs), which consists of an indexed collection of Timed Automata, called …

Nested timed automata with frozen clocks

G Li, M Ogawa, S Yuen - Formal Modeling and Analysis of Timed Systems …, 2015 - Springer
A nested timed automaton (NeTA) is a pushdown system whose control locations and stack
alphabet are timed automata (TAs). A control location describes a working TA, and the stack …

X Cai, M Ogawa - International Symposium on Functional and Logic …, 2014 - Springer
This paper investigates a general framework of a pushdown system with well-quasi-ordered
states and stack alphabet to show decidability of reachability, which is an extension of our …

On timed scope-bounded context-sensitive languages

D Bhave, SN Krishna, R Phawade, A Trivedi - Developments in Language …, 2019 - Springer
Perfect languages, characterized by closure under Boolean operations and decidable
emptiness problem, form the basis for decidable automata-theoretic model-checking for the …

Towards an efficient tree automata based technique for timed systems

S Akshay, P Gastin, SN Krishna, I Sarkar - arXiv preprint arXiv:1707.02297, 2017 - arxiv.org

Schedulability analysis of timed regular tasks by under-approximation on WCET

B Fang, G Li, D Sun, H Cai - International Symposium on Dependable …, 2016 - Springer
Schedulability analysis is one of the most important issues in developing and analyzing real-
time systems. Given a task system where each task is characterized by a worst-case …

Reachability relations of timed pushdown automata

L Clemente, S Lasota - Journal of Computer and System Sciences, 2021 - Elsevier
Timed pushdown automata (tpda) are an expressive formalism combining recursion with a
rich logic of timing constraints. We prove that reachability relations of tpda are expressible in …

On reachability analysis of pushdown systems with transductions: Application to Boolean programs with call-by-reference

F Song, W Miao, G Pu, M Zhang - 26th International Conference …, 2015 - drops.dagstuhl.de
Pushdown systems with transductions (TrPDSs) are an extension of pushdown systems
(PDSs) by associating each transition rule with a transduction, which allows to inspect and …

Adding dense-timed stack to integer reset timed automata

D Bhave, S Guha - International Workshop on Reachability Problems, 2017 - Springer
Integer reset timed automata (IRTA) are known to be a determinizable subclass of timed
automata, but it is not known whether they are input-determined, ie, the clock values are …

Y Wen, G Li, S Yuen - Structured Object-Oriented Formal Language and …, 2016 - Springer
As an extension of Timed Automata (TAs), Updatable Timed Automata (UTAs) proposed by
