A rate-based flow control mechanism for avoiding congestion

The rate-based flow control mechanisms for the Available Bit Rate(ABR)service are used to share the available badwidth of a bottleneck switch connected to a bottleneck link fairly and reasonably among many competitive users,and to maintain the buffer queue length of the witch at a desired level in order to avoid congestion in Asynchronous Transfer Mode(ATM)networks.In this Paper,a control theoretic approach that uses a Deadbeat-Response(DR) controller to the desing of a rate-based flow control mechanism is presented.The mehanism has a simple structure and is robust in the sense that its stability is not sensitive to the change of the number of active Virtual Connections(VCs),Simulation results show that this mechanism not only ensures fair share of the bandwidth for all active VCs regardless of the nmuber of hops they traverse but also has the advantages of fast convergence ,no oscillation,and high link bandwidth utilization.

气动工具的噪声防治

气动工具在我国机械制造等各行业广泛应用的同时,工作时的排气噪声对周围环境也造成了一定的污染。介绍了治理噪声所采用的消声装置及设计方法,通过消声后的试验数据及噪声频譜对比分析,用正交试验法解决功率与噪声的矛盾,通过这种方法使噪音降低最大,功率损耗最小,这种消声装置原理治理噪声效果显著。     

A practical, evidence-based approach for means-restriction counseling with suicidal patients.

Assessing a patient's access to potentially lethal means for suicide and taking steps to restrict access to means are common expectations for reasonable outpatient management of suicidal patients. Although scientific evidence supports means restriction as a suicide prevention strategy, means restriction continues to be infrequently utilized by clinicians, in large part because of the general lack of available training and guidance. The present article reviews the conceptual basis and empirical evidence for means restriction, discusses common barriers to means-restriction counseling, and provides practical procedures and tools (e.g., the means receipt, the crisis support plan) for accomplishing means-restriction counseling in routine clinical practice.
