Inter-clouds services build information bridges over computing clouds so as to provide the convenience for electronic commerce and other information services. However, the interactions between clouds have challenges in information disclosure, services spoofing and information inconsistent. This paper proposes a secure interaction and control method for inter-clouds services, which uses information encryption, digital signature,time logic control means, to protect users' privacy and keep the integrity and consistency of cloud customers' request information, and prevent the spoofing of information requests. The results show that the method could prevent the spoofing well in a stable network environment and improve the security of clouds sessions.

研究目的:斜拉桥因跨度大,可能在车辆通过时发生较大的变形,致使结构几何非线性效应变得显著。对斜拉桥进行非线性动力分析可以为桥梁结构设计提供更精确的理论依据。针对大跨度斜拉桥的几何非线性特征及铁路桥的特点,建立结构空间动力分析模型.通过模拟机车过桥的全过程,计算在机车通过时斜拉桥的动力响应.研究结论:求出了主跨300m铁路斜拉桥方案在机车通过时线性分析与非线性分析的动力响应结果,给出了结构位移时程曲线。对于大跨度铁路斜拉桥,非线性分析结果与线性分析结果相比,具有明显差别。在大跨度铁路斜拉桥车激振动分析中,考虑结构几何非线性效应是必要的。

The uplink achievable rate of massive multiple-input-multiple-output(MIMO) systems, where the low-resolution analog-to-digital converters(ADCs) are assumed to equip at the base station(BS), is investigated in this paper. We assume that only imperfect channel station information is known at the BS. Then a new MMSE receiver is designed by taking not only the Gaussian noise, but also the channel estimation error and quantizer noise into account. By using the Stieltjes transform of random matrix, we further derive a tight asymptotic equivalent for the uplink achievable rate with proposed MMSE receiver. We present a detailed analysis for the number of BS antennas through the expression of the achievable rates and validate the results using numerical simulations. It is also shown that we can compensate the performance loss due to the low-resolution quantization by increasing the number of antennas at the BS.

＜正＞ This research examines the affect of five soil matric potential （SMP） treatments （F1 （-15kPa）, F2.（-2.kPa）, F3 （-35kPa）, F4 （-45kPa）, F5 （-55kPa）） under drip irrigation conditions conducted in the North china Plain. The temporal and spatial SMP changes observed in the soil profile along with changes in potato root growth suggest that tensiometers placed immediately beneath the emitter （at 2. cm） can be effectively used in scheduling the drip
