Identifying propagation source in large-scale networks

© Springer Nature Switzerland AG 2019. The global diffusion of epidemics, rumors and computer viruses causes great damage to our society. It is critical to identify the diffusion sources and promptly quarantine them. However, one critical issue of current methods is that they are far are unsuitable for large-scale networks due to the computational cost and the complex spatiotemporal diffusion processes. In this chapter, we introduce a community structure based approach to efficiently identify diffusion sources in large networks

Program of Research and Development on the THORIUM UTILIZATION IN PWRS : Final Report (1979-1988)

Detailed investigations performed for a standard 1,300 MW$_{e}$ PWR show that (Th,U)O$_{2}$ and (Th,Pu)O$_{2}$ fuels can be inserted in 3 and 4 cycle operating schemes without modifications in the fuel assembly or core design. The most important aspects of the fuel cycle have been covered. Ex-gel pelletizing of (Th,U)O$_{2}$ fuel making use of available LWR and HTR fuel manufacturing technology was demonstrated. The most promising applicationfor Th-based fuels at present was proved to be the use of recycle plutonium in extended burnup once-through fuel cycle. The program was performed in a cooperative way between Brazilian and German partners
