random bit generators are critical for information security,cryptography,stochastic modeling,and *** and scalability are key challenges faced by current physical random bit ***,we propose a massively parallel scheme for ultrafast random bit generation towards rates of order 100 terabit per second based on a single micro-ring resonator.A modulation-instability-driven chaotic comb in a micro-ring resonator enables the simultaneous generation of hundreds of independent and unbiased random bit streams.A proof-of-concept experiment demonstrates that using our method,random bit streams beyond 2 terabit per second can be successfully generated with only 7 comb *** bit rate can be easily enhanced by further increasing the number of comb lines *** approach provides a chip-scale solution to random bit generation for secure communication and high-performance computation,and offers superhigh speed and large scalability.

作者： qin Xiao & pang Liping(department of Computer Science, Huazhong university of Science and Technology,Wuhan 430074, p. r. china) department of Computer Science H azhong University of Science and Technology Wuhan 430074 P. R. China

This paper introduces a multi-granularity locking model (MGL) for concurrency control in object-oriented database system briefiy, and presents a MGL model formally. Four lockingscheduling algorithms for MGL are proposed in the paper. The ideas of single queue scheduling(SQS) and dual queue scheduling (DQS) are proposed and the algorithm and the performance evaluation for these two scheduling are presented in some paper. This paper describes a new idea of thescheduling for MGL, compatible requests first (CrF). Combining the new idea with SQS and DQS,we propose two new scheduling algorithms called CrFS and CrFD. After describing the simulationmodel, this paper illustrates the comparisons of the performance among these four algorithms. Asshown in the experiments, DQS has better performance than SQS, CrFD is better than DQS, CrFSperforms better than SQS, and CrFS is the best one of these four scheduling algorithms.

首先对无线个域网(WpAN)应用环境下的干扰模型进行了分析,在此基础上提出了在WpAN工作的系统中引入速率自适应控制算法以提高诸系统的抗干扰性能,并减小对系统内其它设备及不同系统间设备的相互干扰.文章对自适应速率控制算法进行了分析,然后以蓝牙系统为例,给出了自适应速率控制算法对蓝牙系统性能改善的程度,重点讨论了对系统误比特率的影响.仿真结果显示,在理想反馈信道条件下,随着单信道信噪比的改善,自适应速率控制系统的最佳误比特率比固定速率传输系统有1～3个数量级的改善;即使采用简单的双速率自适应控制系统,也可以得到1～2个数量级的改善.由此得到的结果同样可应用于其它工作于无线个域网的系统.
