With the market-oriented reform in power industry, the research on the optimal distribution of load in thermal power plant has highlighted the importance. This paper established a model of the optimal load distribution about turbine, which take the constraints of thermal power plant with the valve point effect. A practical example analysis has verified that this improved algorithm in particle swarm...
To cope with time-attribute and variations of event distribution in dynamic evolving process, an streaming process mining based on time series prediction and hybrid heuristic miner is proposed. A heuristic miner is improved based on post-task of activity in event logs to optimize the initial particle distribution for Particle Swarm Optimization. Furthermore, “aging factor” based on time series attribute...
Reasonable network structure can obviously improve the learning speed and generalization ability of BP network. In this paper, an improved method to determine the number of hidden layer neurons is proposed. The method mainly takes the theory of linear correlation analysis to delete the redundant nodes and assign the weights related to others. What's more, genetic algorithm is used to optimize the...
Due to the facts of wireless data usage being increasing faster now than ever before and more multimedia content being generated by users and uploaded to the network, multi-user MIMO (MU-MIMO) technology would be crucial to improve the LTE-A uplink spectral efficiency for meeting the service demands. On the other side, adopting clustered SC-FDMA technology as the uplink multiple access scheme of LTE-A...
TCP Vegas congestion algorithm was designed for wired networks, but has poor performance when used in mobile ad hoc network. This paper analyses the impact of hops changing in mobile ad hoc network on the performance of TCP Vegas, and presents a new algorithm named TCP Vegas-HA (TCP Vegas — Hops Adaptive) to improve the performance of TCP Vegas in mobile ad hoc network. As the minimum round-trip time...
Batch verification is a method devised to verify multiple signatures as a whole simultaneously. In literatures, we can see that some conventional batch verification schemes cannot effectively and efficiently identity bad signatures. Small Exponent test, a popular batch verification method, has its own problems, e.g., after a test, bad signatures still exist with some escape probabilities. In this...
Gene expression programming is presented here for two stage evolutionary modeling. It uses character linear chromosomes composed of genes which encode expression trees. This feature which is different from existing algorithms allows the algorithm to perform with high efficiency when dealing with the same problem. And then, the analysis of convergence of this algorithm is mentioned. Finally, a numeric...
According to the logic chip design feature, divides the chip work's time signal into 4 kinds: Clock signal, input signal, combination output signal and register output signal. Has analyzed each kind of signal characteristic, proposed and has designed the signal type recognition algorithm in the logic chip restructuring design. The algorithm principle is based on the input-output signal's time delay...
The IEEE 802.1 le standard allows an admission control (AC) criteria based on medium time calculation for contention-based wireless access. In this standard, medium time is derived from minimum physical layer (PHY) rate and static surplus bandwidth allocation (SBA) parameters. However, a pessimistic minimum PHY rate and fixed SBA would result in channel underutilization. Therefore, we propose an efficient...
