  abstract = {Timed automata are among the 
	most widely studied models for real-time 
	systems. Silent transitions (or 
	\(\epsilon\)-transitions) have already been 
	proposed in the original paper on timed 
	automata by Alur and~Dill. We show that the 
	class of timed languages recognized by 
	automata with \(\epsilon\)-transitions, is more 
	robust and more expressive than the 
	corresponding class without 
	\(\epsilon\)-transitions. \par
	We then focus on \(\epsilon\)-transitions which do 
	not reset clocks. We propose an algorithm to 
	construct, given a timed automaton, an 
	equivalent one without such transitions. This 
	algorithm is in two steps, it first suppresses 
	the cycles of \(\epsilon\)-transitions without 
	reset and then the remaining ones.\par
	Then, we prove that a timed automaton such 
	that no \(\epsilon\)-transition which resets clocks 
	lies on any directed cycle, can be effectively 
	transformed into a timed automaton without 
	\(\epsilon\)-transitions. Interestingly, this main 
	result holds under the assumption of 
	non-Zenoness and it is false otherwise.\par
	To complete the picture, we exhibit a simple 
	timed automaton with an \(\epsilon\)-transition, 
	which resets some clock, on a cycle and which 
	is not equivalent to any \(\epsilon\)-free timed 
	automaton. To show this, we develop a 
	promising new technique based on the notion of 
	precise action.}

  abstract = {Thiagarajan and Walukiewicz have defined a
                  temporal logic~LTrL on Mazurkiewicz
                  traces, patterned on the famous
                  propositional temporal logic of linear
                  time~LTL defined by Pnueli. They have
                  shown that this logic is equal in
                  expressive power to the first order theory
                  of finite and infinite traces.\par 
                  The hopes to get an {"}easy{"} decision
                  procedure for~LTrL, as it is the case 
                  for~LTL, vanished very recently due to a
                  result of Walukiewicz who showed that the
                  decision procedure for~LTrL is
                  non-elementary. However, tools like Mona
                  or Mosel show that it is possible to
                  handle non-elementary logics on
                  significant examples. Therefore, it
                  appears worthwhile to have a direct
                  decision procedure for LTrL.\par 
                  In this paper we propose such a decision
                  procedure, in a modular way. Since the
                  logic~LTrL is not pure future, our
                  algorithm constructs by induction a finite
                  family of B{\"u}chi automata for each
                  LTrL-formula. As expected by the results
                  of Walukiewicz, the main difficulty comes
                  from the {"}Until{"} operator.}

                 the decidability of Termination, Coverability,
                 Boundedness and place-Boundedness. In particular, we
                 show counter-intuitive separations between seemingly
                 related problems. Our main theorem is the very
                 surprising fact that boundedness is undecidable for
                 Petri nets with Reset arcs.}

  abstract = "In a one-counter automaton (OCA), one can read a letter
    from some finite alphabet, increment and decrement the counter by
    one, or test it for zero. It is well-known that universality and
    language inclusion for OCAs are undecidable. We consider here OCAs
    with counter visibility: Whenever the automaton produces a letter,
    it outputs the current counter value along with~it. Hence, its
    language is now a set of words over an infinite alphabet. We show
    that universality and inclusion for that model are in PSPACE, thus
    no harder than the corresponding problems for finite automata, which
    can actually be considered as a special case. In fact, we show that
    OCAs with counter visibility are effectively determinizable and
    closed under all boolean operations. As~a~strict generalization, we
    subsequently extend our model by registers. The general nonemptiness
    problem being undecidable, we impose a bound on the number of
    register comparisons and show that the corresponding nonemptiness
    problem is NP-complete.",
