A study on the combination of singular cancellation and AIM

Ming-Xuan Zheng, Hui-Ling Zhao, Zhong-hui Zhao
Near-singularity and far-filed storage in impedance matrix were two difficulties in MoM. In this paper, some simple methods, based on the Duffy transformation, were effectively used in dealing with the near-singularity. For the far part, AIM(Adaptive Integration Method) was used to reduce not only the...

Crowd flow forecast based on SOM neural network in application of energy-saving lighting

Jun-Feng Xu, Li-Xin Ma
Generally the common lights-control is set in the mode of preset time control, which cannot be adjusted and would not meet the requirements of fine and smart control, so the plug-in of Artificial intelligence algorithms can make a big change of common made. SOM (self-organizing feature map network) is...

Jamming method based on dynamical convolution against ISAR

Zhong-Gan Bai, Xing-Song Deng, Wen-Jun Xu, Kun Shu
A new active jamming method based on dynamical convolution against Inverse Synthetic Aperture Radar (ISAR) is set up in this paper. The traditional scatter jammer is non-cooperative with the dispenser's gesture, which makes ISAR easy to identify it. The new jamming strategy improves it in two steps....

Network Optimization for Distributed Memory File System on High Performance Computers

Chun-Jia Wu, Guang-Ming Liu, Xin Liu
On high performance computers, each compute node's demand for memory may be different. Building a distributed file system in idle memory can improve the memory utilization of the whole system. When memory takes place of disk, the Socket-based communication becomes the main bottleneck. As most of current...
