基于Matlab R2011b的卫星轨道计算

文章阐述了计算卫星在地心坐标系中的位置,利用开普勒方程,根据广播星历的21个参数计算出开普勒轨道参数,再结合卫星运动学方程计算出卫星的坐标。在此基础上,利用MALABR2011b软件读取卫星导航(O,N)文件,在MALABR2011b环境中编写计算卫星坐标的程序过程及其重要函数说明和重要代码标注。     

Consumer involvement in research using oral history: ‘What are people's experiences of health and well‐being in Halton?’

The purpose of this paper is to describe a qualitative oral history case study that involved consumers in research and followed a collaborative approach in the north‐west of England. This study had two aims: (1) to increase local voluntary groups research capacity through active involvement in research; and (2) to explore the community's historical perceptions of health and well‐being. The research team included four lay researchers from local voluntary groups supported by an academic researcher. Data collection used semi‐structured interviews based on oral history life stories that focused on health and well‐being. Thematic data analysis and mind maps were used to create a collective narrative. This paper will provide a brief synopsis of the findings from the main themes of health and well‐being, and reflect on the process of consumer involvement in research using oral history. Outputs have included dissemination at a local and national level, increased knowledge and confidence in the research process, and involvement in other related initiatives, such as Local Involvement Networks, partnership working with local libraries and collaboration with the regional archivist.

Comparison of differences in medical costs when new oral anticoagulants are used for the treatment of patients with non-valvular atrial fibrillation and venous thromboembolism vs warfarin or placebo in the US

Abstract

Objective:

Medical costs that may be avoided when any of the four new oral anticoagulants (NOACs), dabigatran, rivaroxaban, apixaban, and edoxaban, are used instead of warfarin for the treatment of non-valvular atrial fibrillation (NVAF) were estimated and compared. Additionally, the overall differences in medical costs were estimated for NVAF and venous thromboembolism (VTE) patient populations combined.     

基于ADAMS的四足机器人运动仿真研究

作为工业机器人的一个主要研究分支,多足机器人具有很强的环境适应性和运动灵活性,正在日益受到重视。应用三维建模软件UG建立了四足机器人的模型,导入到虚拟样机分析软件ADAMS中生成虚拟样机模型,并对四足机器人进行了步态规划,利用MATLAB计算得到机器人关节运动轨迹,导入到ADAMS中,模拟了机器人的实际运动状态,得到其爬行轨迹。利用虚拟样机进行仿真为多足机器人步态规划的研究提供了一种良好的试验方法。
