针对医疗保健领域人体生理监护需要,提出基于IEEE 802.15.4的人体生理信号监测无线个域网(Physio- logical Monitoring-Wireless Personal Area Netwlork,PM-WPAN),在人体范围内采集、传输各种基本生理信号。该低速、低复杂度无线网络具有高可靠性、低成本和低功耗的特点。设计了PM-WPAN传感节点部署、工作频段、拓扑结构、媒体访问模式等相关网络通信机制。通过网络仿真对其吞吐量、延迟和丢包等性能进行了研究,证明该PM- WPAN能够满足生理监护需要。
This paper discusses the design of the queue for DNA-based computer on the point view of data structure. The nucleotide encodings for all components of the queue are given out formally. The linear double-stranded DNA molecules are used as the storage structure of the queue, and the basic bio-operations over the queue are described. Furthermore, the comparison between the queue of the electronic computer and that of DNA-based computer are elucidated. To prove the feasibility of our work, nucleotide encodings for an instance of queue are given out. All the biological technology mentioned in this paper can be practically implemented in the laboratory. Based on this work, other data structures could be developed in DNA-based computer.
