A novel model of grid cells (GCs) to place cells (PCs) based on radial basis function network (RBFN) is proposed. The connection between multi-scale GCs and a PC is established through RBFN. For each PC, it is associated with a learned RBFN. During vehicle's space exploration, PCs and RBFNs are recruited flexibly after analysing the firing status of the existing PCs, and the transformation from GCs...
Video processing considering human visual perception attracts more attention in recent years. Based on characteristic of visual perception, a guided preprocessing method for multiview coding is proposed in this paper. Texture preprocessing is fulfilled by Gaussian filtering on the background, which led by the mask determined by depth map. And guided filtering is adopted for depth preprocessing, where...
This study primarily focuses on solving the vehicle routing problem with soft time windows (VRPSTW) by applying an improved double-population genetic algorithm (DPGA). The traditional single-population genetic algorithm (SPGA) in solving vehicle routing problem usually traps in local optimum or consumes considerable time. In this paper two different initialization methods - random initialization method...
The protein synthesised from the C/EBPβ gene interacts specifically with a C/EBP-recognition sequence and acts as a transcriptional activator. It plays a key role in lipometabolism and therefore is considered as a candidate gene for goose fat liver forming. In order to get the sequence, four pairs specificity primers were designed for amplification of C/EBPβ gene in Landes geese. The fragments of...
