ABFKS: Attribute-Based Encryption with Functional Keyword Search in Fog Computing
Attribute-based encryption Keyword search Fog computing
2019/8/2
We provide a new frame in this paper, the ciphertext-policy attribute-based encryption with functional keyword search (ABFKS) in fog computing. The ABFKS achieves functional keyword search and peer-pe...
RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Fog detection, Radiative Transfer Model SBDART Indo-Gangetic plain Brightness temperature difference threshold Middle Infrared Thermal Infrared
2019/2/28
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...

2018/5/15
In view of that difficulty of distinguish between sea fog and low cloud by optical remote sensing mean, the research on spectral characteristics of sea fog is focused and carried out。The satellite las...
针对动态Allan方差运用固定长度的分析窗截取信号导致样本数据量减少，长相关时间下方差估计值置信度降低，首先，针对动态信号跟踪能力与置信度的提高不能兼顾的问题提出了一种改进算法。引入截断窗内峭度值作为表征信号短时稳定度的参数，并建立以峭度为变量的窗宽函数，该函数可以使截断窗长随着信号的平稳程度自动变化。其次，再用窗宽自适应的滑动窗分段截取陀螺随机误差，分别对每个截断窗内样本进行总方差计算以增加方差...
