摘要：在医学科研中，研究者常根据研究目的和试验条件选择试验设计方案，如完全随机设计、随机区组设计、析因设计等。在这些试验设计中，各处理因素同时作用于同一级别的受试对象，且处理因素间没有主次之分。因此在方差分析时，往往用标准误差结构（standard error structure），即以模型的误差项作为分析各处理因素的误差项。然而在实际工作中，根据研究目的，各处理因素可能有隶属关系或主次之分，如系统分组(嵌套)设计；或由于试验的特性各处理因素先后作用于不同级别的受试对象，如裂区设计；或对同一受试对象先后多次测量同一观察指标，如重复测量设计等等。这类资料在方差分析时需要考虑非标准误差结构(nonstandard error structure)，即分析不同处理因素作用时要用到不同层次的误差项。本文通过实例分析上述三种具有非标准误差结构的试验设计的变异分解规律及其相应的SAS程序，以便更深入地理解几种常用试验设计方差分析的基本思想及其相互关系。

The scanning sound intensity method can get the convergent feature of sound power. The convergent feature is studied. The error analysis of scanning sound intensity as objective function, the design variable which made up of the sizeof scanning measuring surfaces of isosceles triangle, the distance between measuring surface and sound source, and the density of scanning line, all of which optimized by GA. This optimization determines the geometry parameters of measuring surface, ensures the measuring accuracy, also improves the measuring efficiency .

摘要：In this paper a trial has been made to design a simple self-tuning LabVIEW-based PID controller. The controller uses an open-loop relay test, calculates the tuned parameters in an open loop mode of operation before it updates controller parameters and runs the process as a closed-loop system. The controller reacts on a persistent offset error value as a result of load disturbance or a set point change. Practical results show that such a controller may be recommended to control a variety of industrial processes. A GUI was developed to facilitate control-mode selection, the setting of controller parameters, and the display of control system variables. GUI makes it possible to put the controller in manual or self-tuning mode.

摘要：The downlink minimum bit error rate (MBER) transmit beamforming is directly designed based on the uplink MBER receive beamforming solution for time division duplex (TDD) space-division multiple-access (SDMA) induced multiple-input multiple-output (MIMO) systems, where the base station (BS) is equipped with multiple antennas to support multiple single-antenna mobile terminals (MTs). It is shown that the dual relationship between multiuser detection and multiuser transmission can be extended to the rank-deficient system where the number of users supported is more than the number of transmit antennas available at the BS, if the MBER design is adopted. The proposed MBER transmit beamforming scheme is capable of achieving better performance over the standard minimum mean square error transmit beamforming solution with the support of low-complexity and high power-efficient MTs, particularly for rank-deficient TDD-SDMA MIMO systems. The robustness of the proposed MBER transmit beamforming design to the downlink and uplink noise or channel mismatch is investigated using simulation.

摘要：电子制造业生产成本的剧烈竞争，对于以委托代工（OEM）为主的现代SMT工厂，传统的手工及口头的资讯传递与管理方式，令生产现场与管理层之间无法实时畅通，这不仅难以满足当今自动化生产和先进工艺管理要求，而且导致企业竞争力下降。因此，大家迫切地需要寻找一种全新的现场控制与智能化管理系统（参考图1），以便解决生产现场与管理层信息的滞后或脱节问题。在众多的企业管理软件系统中.

摘要：A novel kind of multidimension symbol/sequence trellis coded modulation (TCM) based on TCM of lower coding rate has been constructed. The redundancy of this new kind of TCM is provided not only by the modulated symbol sequence but also by the PN sequences for spreading spectrum as well. The performance of direct sequence spread spectrum multiple access (DS/SSMA) system with this symbol/sequence TCM over flat Rayleigh fading channel has been investigated by theoretical analysis and numerical simulation. The results obtained in this research demonstrate the performance improvements of this system in comparison with that of the DS/SSMA system with conventional TCM under the same conditions.
