This paper introduces an online precision spindle rotation error measurement system based on three point method. In this measurement system, the connection of software and hardware, data acquisition and processing, results displaying and saving and other functions have been realized. The feasibility and reliability of the measurement system have been proved by the measurement of a machining center...
In the context of product line engineering (PLE), providing immediate feedback on the correctness of a manual configuration step to users has a practical impact on whether a configuration process with tool support can be successfully adopted in practice. Model-based PLE has brought opportunities to enable automated product configuration and derivation for large-scale systems/software, in which models...
It is well acknowledged that environment plays an important role in requirement derivation. However, at present the time-continuous properties of the environment are of little concern. Our previous work modeled the time-continuous environment by constructing a software environment ontology. This paper further presents an approach for deriving software requirements specification with time using software...
The PSL-to-Verilog (P2V) compiler can translate a set of assertions about a block-structured software program into a hardware design to be executed concurrently with the program. The assertions validate the correctness of the software program without altering the program's temporal behavior in any way, a result never previously achieved by any online model-checking system. Additionally, the techniques...
