The hybrid architecture analysis and design language (AADL) has been proposed to model the interactions between embedded control systems and continuous physical environment. However, the worst-case performance analysis of hybrid AADL designs often leads to overly pessimistic estimations, and is not suitable for accurate reasoning about overall system performance, in particular when the system closely...
Unified Modeling Language (UML) activity diagrams are widely used in modeling the dynamic aspects of system designs. However, due to frequent interactions between systems and external uncertain environment, the current version of UML activity diagrams cannot be used to accurately capture and quantify the overall timing behaviors of complex systems. To address this issue, this paper extends the UML...
Under the increasing complexity and time-to-market pressures, functional validation is becoming a major bottleneck of smartphone applications running on mobile platforms (e.g., Android, iOS). Due to the GUI (Graphical User Interface) intensive nature, the execution of smartphone applications heavily relies on the interactions with users. Manual GUI testing is extremely slow and unacceptably expensive...
