摘要：There is a sharp decline in the network performance when the wireless link fails as a data path in the Wireless Network-on-Chip(WiNoC).To counteract this problem,we propose a fault-tolerance mechanism for the efficient retransmission of data in the *** an error is detected in the data transmission process,this mechanism works to feed back the fault information to the source node in real time via fault signal *** the source node,the highest transmission priority is assigned to the backup retransmitted data,and the corresponding direct link is positioned to enable the data packet for its efficient retransmission to the destination node,thereby ensuring efficiency in fault ***,we have improved the receiving port of the wireless router,added the corresponding redundant buffers and mux,and dynamically selected the retransmitted non-faulty data packets to be written to the local router in order to avoid the disorderly retransmission of the data *** evaluation results of this paper demonstrate that compared with the methods which are under different fault conditions,this fault-tolerant method drastically improves the data throughput rate,reduces the delay,effectively guarantees the reliability of the network,and improves the system performance.

摘要：针对遭受稀疏恶意攻击的离散时间线性系统,本文研究其安全控制问题.假设恶意攻击者受有限资源的约束,仅能操控远程控制器和执行器之间的若干通信通道.对于设计者来说,并不知道哪些通道受到攻击,哪些通道没有受到攻击.本文提出了一种新的安全的远程控制方法,它由控制律、切换函数和选择机制构成.选择机制为控制律提供合适的反馈增益,并产生一个切换函数,用以阻止攻击信号进入被控对象.理论分析表明,在基本的和必要的假设条件下,本文考虑的安全控制问题可转化为求解状态反馈镇定问题.本文所提控制方法,能保证闭环系统的稳定性且使其具有"PID"型性能的抗攻击能力.最后,通过对某无人地面车辆系统的仿真实验,验证了理论结果的正确性.

摘要：In this paper, we discuss some fundamental properties of two idealized typical networks, namely, grid type and radial-circular type. The discussion is based on SPCP （Shortest Path Counting Problem）, which reflects the traffic density of a road segment. Furthermore, we compare their effectiveness based on the obtained results of the above two road networks, and suggest some proposals on the design of car lanes by considering the direction of a road segment in relation to these road networks.

摘要：随着采油技术的发展,注空气采油技术受到国内外很多油田的重视,但空气中氧的存在,会给油田管线及其他设备带来严重的腐蚀问题。为了明确注空气驱的腐蚀主导因素、腐蚀规律及腐蚀机理,利用高温高压反应釜模拟工况条件对油田所提供的20#与L360两种材质进行腐蚀试验,通过金相显微镜与X射线衍射仪对腐蚀后试样的形貌与产物进行表征分析,研究不同氧含量、压力与温度条件下材质的腐蚀规律与机理。通过分析得出:腐蚀速率随着氧含量、压力与温度的升高而升高;从金相显微镜观察可知,腐蚀类型为点蚀与溃疡腐蚀;XRD分析得到腐蚀产物的主要成分为铁的氧化物。腐蚀的主导因素为氧含量,油田在生产作业中应适当控制所注空气的氧含量。
