We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS3 with a sevendimensional internal space. In one duality frame the only other nonvanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to globally well-defined solutions of type IIB string theory, with the int...

Dempster-Shafer (D-S) evidence theory is regarded as an effective method of dealing with the uncertainty information but still suffers from conflict problem among evidence. Despite that various techniques were presented in plenty publications, currently, there no convincing and firm conclusion about optimum solution. This study presents Belief Coulomb Force (BCF) into D-S theory, where Zhou et ...
