The Multitarget Multi-Bernoulli (MeMBer) filter has been proposed as a computationally tractable approximation of the multitarget Bayes filter, but with significant bias in the cardinality estimates. In this paper, a new improved MeMBer filter is proposed as a solution to address these limitations, with stable and accurate cardinality estimates achieved. The biases derived from the two approximations...
The Orthogonal Frequency Division Multiplexing (OFDM) is one of the key technologies for new moblie communication. Multipath interference to send and receive signals. In the China Mobile Multimedia Broadcasting (CMMB) system will cause serious SNR loss, influence on the reliability of the system and timing accuracy. Through the research of OFDM technology of anti-jamming, understand many advantages...
With the increasing number of subway stations, more and more attention has been paid to their emergency evacuation, as it plays an important part in urban emergency management. The present paper puts forward a method of crowd evacuation simulation for bioterrorism in subway station environment using the basic theory of the Social Force Model combined with the Gaussian Puff Model. A Combined Social...
In this paper, we investigate the vehicle scheduling problem for rescuing victims under the context of multi-location chemical and biological terrorist attacks (CBTAs). A mathematical model is proposed to choose available hospitals for each victim point according to the prime rescue time and dispatch vehicles to transport victims to hospitals depending on the hospitals' treatment capacity. An ant...
As a new general-purpose heuristic algorithm, Ant Colony Optimization Algorithm(ACO) has been applied to combinatorial optimization problems. The main characteristics of ACO are positive feedback, distributed computation and the use of constructive greedy heuristic. This paper presents the principle and the hierarchy model of the ACO with small-perturbation. This algorithm is applied to the optimization...
Congestion control is an important strategy to switches and routers, this paper proposes a novel congestion control algorithm based on active queue management, which control the buffer queue size by delay jitter. Simulation results show that the proposed algorithm outperforms these popular algorithms in quality of service and fairness.
