哈尔滨工程大学word格式论文，基于差分演进算法的TDOA定位技术。提出了三种新的定位算法：基于TDOA的Chan-GA算法、Chan-DE算法和Chan-IDE算法。并在相同的仿真环境下进行比较，仿真结果表明，在保证种群数量的情况下，所提的算法性能稳定，能找到逼近全局最优点的解，相对于Chan算法精度更高,相对于以前的算法在保证收敛性能的前提下有更快的收敛速度。(Harbin Engineering University, word format papers, based on differential evolution algorithm TDOA positioning technology. Proposed three new localization algorithm: Based on TDOA Chan-GA algorithm, Chan-DE algorithm and Chan-IDE algorithms. And in the same simulation environment to compare simulation results show that, in the case of populations to ensure that the proposed algorithm performance and stability, can be found close to the global optimal solution, Chan algorithm with respect to higher accuracy compared to the previous algorithm convergence performance guarantee under the premise of a faster convergence.)

医学信息学是一个新兴的领域，医疗信息系统是医学信息学的一个重要分支。虽然也不乏很多在临床上已经应用的系统，但由于缺乏一个理论的指导，发展呈无序状态。各开发商在进行医疗信息系统建设时往往直接套用其它领域的信息系统开发理论，以满足医疗机构的暂时需求为主要目的，造成开发出来的产品各自为政，重复开发，而且彼此之间很难互连。我国在医疗信息系统领域的起步较晚，最近几年才开始进行系统的研究和开发。 建立并完善医疗信息系统的理论体系是目前医疗信息系统领域十分迫切的要求。本论文以建立整套理论体系为长远目标，以分布式异构系统集成为主要问题对象，从理论和实践两个方面对医疗信息系统的体系结构进行了深入的研究；构建了针对系统集成的医疗信息系统体系结构；设计并实现了医疗信息系统的开发平台。具体来说，本文主要包含以下内容： 从医学信息和医疗信息系统两个方面对医疗信息系统理论体系所涵盖的内容进行了分类总结和综述，为从事医疗信息系统研究、开发、维护、使用的工作人员提供了一个理论基础。 在分析了目前流行的信息系统体系结构的基础上，基于中间件理论提出了医疗信息系统体系结构的设计，从技术平台和医疗模型两个层...(Medical Informatics is a rising field of research with Medical Information System as one of its important branches. Although many information systems have been applied in clinical practice, since they are in lack of theoretical guidance, the development has been a disorderly one. The developers mechanically copy the development of information system from other fields to temporarily meet the demand in healthcare institutes, hence the products ever developed are either irrelative or repetitive and can not be )

说明：  3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的，但由于Windows系统与其他系统如Linux等的文档结构不同，项目的可移植性将会受到限制，因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的，我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本，基础代码部分不变，只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月，包括平台的移植，接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)
