We further investigate the dimensional duality (D-duality) proposed in arXiv:0705.0550 by mainly focusing on the properties of D-branes in this background. We derive the world-sheet correspondence of static D-branes, and discuss the fate of non-static D-branes from the world-sheet viewpoint. The quantum string production with or without D-branes is also studied from the time-like Liouville theo...

Long term defence planning is a complex undertaking involving many separate analytical steps and with non-trivial transitions from one step to the next. Many nations struggle with the challenge of establishing analytical rigour, structure and traceability in their defence planning processes. In this paper we will present a tool that has been developed not only to support defence planning, but w...
