工业大数据与服务大数据及其检测要点对比研究

当前,大数据已成为社会各个领域热议的问题,然而面对新概念、新技术,大众往往一概而论,专业人员也容易忽略新技术在不同应用领域的不同之处.工业大数据与服务大数据的不同,就是这样容易被忽略的一对关系.从技术框架体系和数据生命周期各个环节对工业领域大数据和服务领域大数据进行了对比分析,分析了工业大数据检测与服务大数据检测要点的异同.对于认知工业大数据和服务大数据的不同及其相应的检测技术具有一定的参考意义.     

软件密集型装备软硬件故障模式研究

针对软件密集型装备的故障特征,采用文本聚类的方法对收集的软硬件故障数据进行聚类分析,并根据软件密集型装备中软件与硬件、 环境相互作用的故障特点,提出了"环境特征类型-硬件故障模式-软件故障模式"的软硬件故障模式表示方式,最终提炼并形成了软件密集型装备软硬件故障模式,为装备故障的定位、分析和诊断提供了有益的参考.     

The test pulse line ion accelerator in Lanzhou

To accelerate intense, short pulsed heavy ion beams to the energies of interest for studies of high energy density physics and warm dense matter, the Pulse Line Ion Accelerator (PLIA), of which the axial acceleration gradient can achieve several MeV per meter with realistic helix parameters at very low cost, was developed in recent years. A simple prototype of PLIA for a proof-of-principle experiment called the Lanzhou Test PLIA was designed and constructed at the Institute of Modern Physics in Lanzhou, and the test result matches the calculated result well. The pattern of the axial electric field Ez and the velocity of the traveling wave were simulated by CST.
