Systems Science and Systems Engineering 1998年第4期8卷 432-437页

作者： XIA Guoping liu silong Wang Zhonghua(Management School, Beijing University of Aeronautics & Astronautics,Beijing 100083, P.R.Chjna)

Recently we develop a new conceptual model for group decision support Systems. Themodel is based on the information communication theory, minority ducting theory and human physicaland mental limited theory described by Srinvasan & Sirkkal(1991)[1]. The new model tells how to reducethe noise and enhance the information communication and then enhance GDSS function; it tells howto provide the minority effect to enhance GDSS function; it tells how to reduce knowledge resourceconsumption and enhance knowledge resource and enhance GDSS ability. The authors developed thenew GDSS system in LAN and WAN environment.

Chinese Journal of Electronics 2019年第5期28卷 1008-1017页

This paper proposes a flexible design scheme for H.265/HEVC encoding based on FPGA, which allows an easy incorporation of a variety of algorithms applied to different scenarios. In particular, we present an H.265/HEVC intra encoder as an instantiation of our proposed scheme. The key idea is to develop an encoder system by configuring basic Processing elements(PEs) of fundamental algorithms. Our intra encoder using the flexible framework is structured with fourstage CTU based pipeline. Pixel-level PEs are designed to unify the intra prediction of 35 modes and a multiscale compatible transform array is proposed to process variable size transform. 32 PEs are paralleled for intra mode decision to support 35 combinations of modes and partitions. In the reconstruction stage, 16 PEs are paralleled for intra prediction and a 16 × 16 multiplier array is configured for transforms of variable sizes with a constant 16 pixels/cycle throughput. Implementation results show that our proposed architecture costs about63 K Lookup tables and 62 KB on-chip memories on Xilinx Kintex-7 platform with the maximum working frequency at 175 MHz, which is sufficient for real-time encoding of 1920 × 1080 @60 fps video at 160 MHz. The flexibility and extension capability of our framework provides a great potential for future FPGA solutions serving for different purposes.

三维地质雷达技术在城市地下病害体探测领域发挥了重要作用,长期以来保障了城市公共设施的运营维护安全,极大地降低了地面塌陷的发生概率。但目前海量实测三维地质雷达数据解译缺乏标准化、定量化的异常解译标志,主要依赖工作经验,这导致解释过程中存在对病害异常的错判和漏判问题。为统一异常判别标准,本文针对空洞、脱空与疏松体三种地下病害体进行了三维地质雷达数值模拟研究,采用时域有限差分方法实现了正演模拟数据的三维成像,总结归纳了反褶积与偏移处理前后不同地下病害体的典型二维、三维异常特征,并准确估算了地下病害体边界分布与发育规模信息。经与实测数据对照分析得出,地下病害体理论模型异常特征具有普适性,相关成果能够推广,为实际工作提供指导。
