TBB (Thread Building Blocking) is currently a representative parallel computing platform of multi-core processors. The ant colony algorithm is used to solve combinatorial optimization problem of discrete-time systems. With the expansion of the problem scale, it often results in rapid increase of calculation. Based on TBB a parallel ant colony algorithm was(More)
A subliminal channel is a covert communication chsnnel to send a message to an authorised receiver; this message cannot be discovered by any unauthorised receiver. There are some applications that can take advantage of this by hiding secr1:t messages in this subliminal channel. For example, a credit card provider can hide the card holder's credit history(More)
We give an up-to-date survey on techniques and methods for fire simulation in computer graphics. Physically-based method prevails over traditional non-physical methods for realistic visual effect. In this paper, we explore visual simulation of fire-related phenomena in terms of physically modeling, numerical simulation and visual rendering. Firstly, we(More)
