The application of evolutionary algorithms to CDMA multiuser detection has been studied for more than a decade. But not all variants of these algorithms can be directly applied to binary sequence detection. In this paper, we proposed a novel Particle Swarm Optimization (PSO) method. PSO is transformed into a completely binary algorithm, which is ideal for hardware to run. The new approach is successfully...
Gene chip as a key point research field of bioscience, it's a fast way to analyse the heredity information and diagnose the disease with high efficience. For the filter is the pro-processing of the image segmentation that influenced the outcome of segmentation directly. In this paper a specical filter called Edge Enhance Diffuse. is used to remove the noise and protect the edge. It has a better effect...
The central pattern generator(CPG) is used to control robot very well. But the adjustment of CPG parameters and it's interaction with the external inputs are still open problems. Based on biological knowledge, the central nervous system rules the switch of the CPG modes. In this paper we focus on the coupling relationship between the cerebral cortex and the CPG and establish the mathematical model...
Image recognition is very key importance for image process. Thus, the novel image recognition method based on the hybrid model of support vector machine and artificial life is presented in the paper. The artificial life is the important research method for the traditional biology and the ecology, and the research of artificial life contributes to indicate the most essential feature that life needs...
Lung disease is often performed as nodules. Pulmonary nodule is one of important symbols of lung disease. Characteristics of pulmonary nodules always indicate the nature of lung disease. Detection of pulmonary nodules has great significance in diagnosing lung cancer. Study of pulmonary nodules is now a hot research. CT is a new type of medical imaging equipment with a high density resolution and adequate...
In order to optimize the human-computer interaction technology of 3D interface, and solve the problem of realizing the three-dimensional moving operations via two-dimensional plane by controlling the mouse, after achieving the target of model can move freely in 3D space, it has researched the algorithm of models move intelligently in 3D space, by introducing the thought of bounding box and using improved...
This paper proposes a modified version of opinion communication based on naming game to simulate the formation of opinion in real society. In the version, freshness is brought in to measure memory level of one opinion for each agent, when various opinions exist in social population. Main researches are devoted to new opinion replacing old opinion after system already convergences to an opinion, revealing...
This paper introduces an evolutionary model for complex networks on public goods game, which is a dynamical simulation for the real society. The degree distribution of this network is similar to the real society which is closed to Poisson distribution in the first part of process and in accordance with power law distribution in the second. The clustering coefficient of network is enhanced by the cooperator...
With the continuous development of network, the damage of the public opinions spreading is expanding. It is researched that under the effect of the herd instinct, how does the process of the individuals in the network cognize the public opinions evolve, uses the coordination game with the factor of non-rational to building the model of interaction among the neighbors. It has been studied that individuals'...
A brain-computer interface (BCI) is a system for direct communication between brain and computer. The P300 BCI system relies on an oddball paradigm to elicit the P300. With the aim to extract different P300 feature information from different subjects and reduce the data amount of electroencephalogram (EEG) in P300 classification, a P300 feature extraction algorithm is proposed, which is based on independent...
