Toward Energy-Efficient and Trustworthy eHealth Monitoring System

The rapid technological convergence between Internet of Things(IoT),Wireless Body Area Networks(WBANs)and cloud computing has made e-healthcare emerge as a promising application domain,which has significant potential to improve the quality of medical care.In particular,patient-centric health monitoring plays a vital role in e-healthcare service,involving a set of important operations ranging from medical data collection and aggregation,data transmission and segregation,to data analytics.This survey paper firstly presents an architectural framework to describe the entire monitoring life cycle and highlight the essential service components.More detailed discussions are then devoted to {\em data collection} at patient side,which we argue that it serves as fundamental basis in achieving robust,efficient,and secure health monitoring.Subsequently,a profound discussion of the security threats targeting eHealth monitoring systems is presented,and the major limitations of the existing solutions are analyzed and extensively discussed.Finally,a set of design challenges is identified in order to achieve high quality and secure patient-centric monitoring schemes,along with some potential solutions.     

热连轧磨辊间地坪局部裂陷的分析及处理

裂缝与局部塌陷，是冶金工厂厂房地坪最常见的质量通病，这是由于此类厂房格局多变，务块分割的布局争荷载分布的不均匀性等特点所决定的。因此，通过热连轧车间磨辊间厂房典型的地坪局部塌陷分析与处理，探求避免上述缺陷产生的途径与方法。     

圩区排涝模数计算方法研究

合理确定圩区排涝模数对于降低涝灾损失有重要意义。圩区内土地利用性质的不同,会导致产汇流机制和排涝标准的不同,但排涝模数的计算方法基本一致。本文根据圩区下垫面条件进行产汇流计算,入河流量扣除滞蓄量得到排涝模数,充分考虑到圩内河道的调蓄作用。以常熟市为例,对城镇圩区、农业圩区排涝模数进行计算,并分析了两种圩区不同的排涝要求对排涝模数计算方法的影响。     

美“问题奶粉”引发乳业震动

面对中国媒体的猜测和指责,美国“问题奶粉”的主角Darigold日前首次表示：称该企业生产奶粉里的亚硝酸盐没有超标。据报道,这批“问题奶粉”是由国内一家乳业公司进口。但各方面都表示不便透露这一公司的名字。业内表示,一旦该进口公司的名单被披露,很可能引发行乳业一场震动。
