  • 简介:监视任何结构的表演要求批评的点的位置的变化的即时大小。不同技术能被用于这个目的,一个出现优点和劣势。这种技术基于放系统(GPS,GLONASS和未来伽利略)的卫星似乎为长时期结构至少很有希望。GPS特别地提供能与高精确性追踪动态排水量的采样率。它的服务能力独立于大气的条件,温度变化和监视目标的可见性。这篇论文调查双频率GPS接收装置的大小的可靠性和精确性。一台线性电磁的马达沿着一个给定的方向移动一个目标。位置的变化与他们由GPS接收装置记录了的估计相比,其天线位于参考书目标。比较基于足够地长的记录。

  • 简介:AbstractElectronic health (medical) records, which are also considered as patients’ information that are routinely collected, provide a great chance for researchers to develop an epidemiological understanding of disease. Electronic health records systems cannot develop without the advance of computer industries. While conducting clinical trials that are always costly, feasible and reasonable analysis of routine patients’ information is more cost-effective and reflective of clinical practice, which is also called real world study. Real world studies can be well supported by big data in healthcare industry. Real world studies become more and more focused and important with the development of evidence-based medicine. These big data will definitely help in making decisions, making policies and guidelines, monitoring of effectiveness and safety on new drugs or technologies. Extracting, cleaning, and analyzing such big data will be a great challenge for clinical researchers. Successful applications and developments of electronic health record in western countries (eg, disease registries, health insurance claims, etc) have provided a clear direction for Chinese researchers. However, it is still at primary stages in China. This review tries to provide a full perspective on how to translate the electronic health records into scientific achievements, for example, among patients with diabetes. As a summary in the end, resource sharing and collaborations are highly recommended among hospitals and healthcare groups.
