大体积混凝土施工温度应力分析与控制

文章采用有限元结构分析软件对某拱座进行了混凝土施工期间的温度应力计算分析,计算过程考虑了混凝土的弹性模量、徐变等参数随龄期变化和分层浇筑对拱座温度应力产生的影响,提出了防止施工过程中由于外界温度变化及水泥水化热等因素引起裂缝的措施,并通过部分监控数据对拱座温度变化规律进行了分析。

Multiple MIPS 4Kc cores based interrupt controller design and its implementation on HDTV SoC platform

A multiple MIPS 4Kc processor cores based interrupt processing system is introduced. The interrupt controller plays a key role in the high definition television （HDTV） system-on-a-chip （SoC） platform, especially when it is a multiple processor system. Based on a general introduction to the whole HDTV SoC platform, a layered interrupt controller and its implementation are discussed in detail. The proposed scheme was implemented in our FPGA verification board. The results indicate that our scheme is reliable and efficient. Meanwhile, as a functional intellectual property （IP）, the interrupt controller has reusability and expandability with the layered structure.     

米索前列醇预防产后出血临床观察

目的探讨产妇舌下含服米索前列醇预防产后出血的效果.方法实验组100例产妇于胎头着冠时舌下含服米索前列醇600μg,对照组90例产妇于胎肩娩出后立即静脉注射缩宫素20IU.用容积法和称重法测量两组产妇的产后出血量.结果实验组产妇产后失血量平均为(116.43±94.32)ml,对照组产妇产后失血量平均为(296.52±79.41)ml,两组产妇产后失血量差异显著(P《0.01).结论舌下含服米索前列醇可有效减少产妇的产后失血量.     

An algorithm for three-way data analysis that alternatively minimizes coupled vector (COV) resolution error and PARAFAC error.

A novel algorithm, alternatively minimizing coupled vector (COV) resolution error and PARAFAC error algorithm, is proposed in this paper. This algorithm can overcome the problem of slow convergence and is insensitive to the estimation of component number, such problems are unavoidable while using the traditional parallel factors analysis (PARAFAC) algorithm. In other words, this algorithm is capable of improving the computing speed and providing accurate resolutions provided that the number of factors used in the computation is no less than that of the actual underlying ones. The characteristic performances were demonstrated with a novel fluorescence data array.
