As a theoretical basis of computerized adaptive test, item response theory (IRT) has been the focus point of research on test theory of education at present and broken through the limitation of the classical test theory. The ability of examinee is related with his response in examination, and all of them are parameterized by IRT. At present, the research on computerized adaptive testing (CAT) based...
At present, several feature meta-models have been come up with. However, they can't meet the requirements of dynamic Internet environment or software reuse. This paper proposes a feature meta-model based on ontology. In particular, it can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Finally, we give out...
The disadvantages of the current architectures of the Ad hoc were analyzed. After that, an adaptive hiberarchy of the formation C4ISR system was given. The system based on both the plane architecture and the adaptive hiberarchy was simulated. The control spending of the two architectures were compared under the all kinds of the system scope. The simulation shows that the adaptive hiberarchy is better...
