This paper presents a modular designed dynamic positioning (DP) experiment system. Three modules are designed for the DP experiment system, which are onboard computer module, position sensing module and onshore control computer module. The hardware system and software are introduced. A PC/104 computer is used as the main controller of the onboard computer system, and an ARM microcontroller is used...
Based on the basic concept of the goal lay of the requirement meta-modeling frame for network software(RGPS-G), this paper advanced a new formal method to guarantee its correctness. The importance of introducing the formal method into RGPS-G was discussed based on the characters of RGPS-G. Theorem proving and model checking had merged in this formal method. Simple formal normative language was used...
Formal methods have been widely used in computer science and being improved day by day. Towards finite relation models, this paper advances a new formal method used by sextuple based on symbolic logic. It can use simple formal normative language to depict the relation between the modules in model exactly. With logical reasoning, it can analyse the models with theorem proving and model checking. In...
Methodology of automatic generation of test cases based on Model Driven Architecture is proposed, and its design and implementation have be done. The process of generating test cases is that a platform-independent model is converted into a platform-independent test model through level conversion, and the platform-independent test model is converted into the corresponding test cases through vertical...
Isolation between antennas is one of the most important indexes for electromagnetic compatibility (EMC) problem on airborne platform. Take the Rooivalk helicopter for example, as the electrically size of the airborne platform is large, the structure is complex, the simulation results are usually not accurate enough. Due to the inaccuracy of the former modeling method which used the simple typical...
