In this paper we study the issue of progress for distributed timed systems modeled as the parallel composition of timed automata. We clarify the requirements of discrete progress (...
To perform veri cation of digital systems with time bounded delays, it is essential to characterize the space of all possible system behaviors. In this paper, we describe our analy...
In this paper we firstly analysis the chaotic characters of three sets of the financial time series (Hang Sheng Index (HIS), Shanghai Stock Index and US gold price) based on the ph...
A crucial problem in non-linear time series forecasting is to determine its auto-regressive order, in particular when the prediction method is non-linear. We show in this paper tha...
The Ravenscar profile for Ada enforces several restrictions on the usage of general-purpose tasking constructs, thereby facilitating most analysis tasks and in particular functiona...
