A defender protects a target from being attacked. It can carry out two kinds of strategies. One is passive defense strategy. The other is active defense strategy. When the defender executes the passive defense strategy, it can deploy camouflage to misinform the attacker. When the defender runs the active defense strategy, it strikes the attacker preventively. Then, the defender will reveals itself...
Novel advanced game techniques provide us with new possibilities to mimic a complicated training process, with the benefit of safety enhancement. In this paper, we design and implement a 3D game which imitates the lifeboat launching process. Lifeboat launching is such a complex but vital process which can on one side saving people's life on sea and on the other side associating many potential hazards...
We study the novel problem of finding new, prominent situational facts, which are emerging statements about objects that stand out within certain contexts. Many such facts are newsworthy—e.g., an athlete's outstanding performance in a game, or a viral video's impressive popularity. Effective and efficient identification of these facts assists journalists in reporting, one of the main goals of computational...
Deploying false targets is an effective measure to increase the survivability of genuine object when it encounters intentional attacks. Existing researches have mainly assumed that the false target is perfect or can be detected with a constant detection probability. In this paper, it is assumed that both genuine object and false target are possible to be detected. The detection probability of the...
The paper first constructs two different third-party B2B e-commerce platforms according to the different ways of charging methods, and then analyses of the dynamic game between the two platforms. In the dynamic game, I establish a triangular model to describe the distribution of the seller, and on this basis, I construct a nine-cell matrix of the dynamic game to measure the results of the game accurately,...
Traffic-aware dynamic spectrum access (TDSA) can improve spectrum usage efficiency through demand driven spectrum allocation with the aid of cognitive radios. However, selfish behaviors of participants, such as deviation for more spectrum, can decrease the efficiency of TDSA a lot. In this paper, we prevent APs' deviation in FLEX with trigger punishment in the repeated game. The new TDSA solution...
Traffic-aware dynamic spectrum access (TDSA), in which demand-driven spectrum allocation is employed with the aid of cognitive radios, can improve the performance of the wireless network with increasing and dynamic user demands. However, selfish behaviors of participants, such as cheating and deviation for more spectrum, can decrease the efficiency of TDSA a lot. In this paper, with the help of game...
We consider the problem of efficiently computing weighted proximity best-joins over multiple lists, with applications in information retrieval and extraction. We are given a multi-term query, and for each query term, a list of all its matches with scores, sorted by locations. The problem is to find the overall best matchset, consisting of one match from each list, such that the combined score according...
