We discuss a new concept in lightning location system (LLS). Specitically,it is anoptimum method of lightning signal strength and a parameterization method of the site gaincurve estimation in LLS. Site gain correction curves for all DFs for 1989 were found byusing the data observed in an LLS of three direction finders (DFs) in Beijing region. Theresult shows that the curves, as a function of measured bearing, only include the one- andtwo-cycle sinusoidal components. It also indicates that the larger the site errors which DFhas, the larger the amplitude of the site gain curve. In this LLS, the ranges of site gainare 0.9--1.2, 0.85--1.05, 0.9--1.1 for DF1, DF2 and DF3 respectively. For discussion, we suggested a model for site gains due to dipole radiation. This modelcan be used to reasonably explain the characteristics of structure of site gain curves.

重力辅助惯性导航系统gains(Gravity Aided Inertial Navigation System)是利用地球物理特征信息──重力来完成水下运动载体的辅助惯性导航与定位。为实现重力匹配以校正惯性导航随时间累积的误差,首先必须对重力传感器输出信息进行扰动改正。分析了水下运动状态下重力传感器受到的各种重力扰动,如垂直扰动加速度、水平扰动加速度以及厄特弗斯效应影响所产生的原因,研究了扰动误差模型与INS导航精度之间的关系,并通过计算,提出了可直接以INS输出数据而无需其它外部有源导航信息进行扰动分离的方法。

Sustained clinical improvement is unlikely without appropriate measuring and reporting techniques. Clinical indicators are tools to help assess whether a standard of care is being met. They are used to evaluate the potential to improve the care provided by healthcare organisations(HCOs). The analysis and reporting of these indicators for the Australian Council on Healthcare Standards have used a methodology which estimates, for each of the 338 clinical indicators, the gains in the system that would result from shifting the mean proportion to the 20 th centile. The results are used to provide a relative measure to help prioritise quality improvement activity within clinical areas, rather than simply focus on "poorer performing" HCOs. The method draws attention to clinical areas exhibiting larger between-HCO variation and affecting larger numbers of patients. HCOs report data in six-month periods, resulting in estimated clinical indicator proportions which may be affected by small samples and sampling variation. Failing to address such issues would result in HCOs exhibiting extremely small and large estimated proportions and inflated estimates of the potential gains in the system. This paper describes the 20 th centile method of calculating potential gains for the healthcare system by using Bayesian hierarchical models and shrinkage estimators to correct for the effects of sampling variation, and provides an example case in Emergency Medicine as well as example expert commentary from colleges based upon the reports. The application of these Bayesian methods enables all collated data to be used, irrespective of an HCO's size, and facilitates more realistic estimates of potential system gains.

Wireless sensor networks have already enabled numerous embedded wireless applications such as military, environmental monitoring, intelligent building, etc. Because micro-sensor nodes are supposed to operate for months or even years with very limited battery power source, it is a challenge for researchers to obtain long operating hour without scarifying original system performances. In this paper, the energy consumption sources of the wireless sensor networks are firstly analyzed, with the digital processing and radio transceiver units being emphasized. Then, we introduce the design scheme of our energy-aware wireless sensor network (gains). In gains, techniques to conserve the energy are exploited including the energy optimization node, software and energy-efficient communication protocol. The design architecture of our ultra low power wireless sensor network (WO-LPP) is specially presented.

首先介绍了工业现场控制对无线通信网络WICN的具体要求,针对其要求分析比较了目前几种常用的无线网络MAC协议的特点,提出了一种基于令牌且能利用目前被普遍使用的CSMA协议的数据链路层控制机制,简称WICN-Z协议。详细叙述了WICN-Z的通信协议栈的结构、主站的定义、令牌环的动态建立和复原过程、各个移动站点的动态加入与离开过程等,定义了几种用到的帧的结构。最后利用OMNet++平台对WICN-Z和CSMA/CA性能进行了仿真比较,并且在基于gains的硬件平台上实现了该协议,且在一个工厂车间现场建立了包括9个移动1个固定站点的一个网络系统,针对数据吞吐量和响应时间指标作了初步的测试。仿真结果和实际测试显示,WICN-Z确保了无线信道接入的公平性,其数据吞吐量大于CSMA/CA,且减少了数据的传输延迟。
