In this paper, to study rum or spreading model for the web forum of which the topological structure has a strong heterogeneity, we propose a novel susceptible-exposed-infected-removed (SEIR) model by introducing the importance and fuzziness of the content of the rum or. We derive mean-field equations characterizing the dynamics of the SEIR model on heterogeneous network. Then a steady-state analysis...
Adaptive networks are common in real world, describing networks whose links change adaptively with respect to its states, resulting in a dynamical interplay between the state and the topology of the network. Recently, it is demonstrated that the diversity in the interaction intensity is also the crucial feature that reflects the complexity. In fact, when topology alters, the strengths of the connections...
Education quality assessment of primary and secondary school teachers is an important part of teacher education. In this paper, a fuzzy comprehensive assessment model for the education quality of primary and secondary school teachers, which combines the experience of experts with quantitative analysis, is proposed. It reduces the influence of human arbitrariness on the assessment, and then enhances...
Web applications are widely used in people's everyday life and are inherent interactive applications since their emergence. The structures of web applications are complex. Furthermore, the interaction features exacerbate their complexity. How to ensure their reliability and quality presents a challenge to software testers. In this paper, according to the features of web applications, we have formally...
On the basis of the maglev spindle structure design, the PID control system is designed and its mathematical model is established. The influence of the PID control parameters on the response performance of the system is studied by using the MATLAB SISO. The global optimization design of the PID control system is achieved by using SRO (Simulink Response Optimization) module, and the system response...
