A non-linear, yet simple, multiplicative human-control model is developed by studying the statistical properties of human subjects' motor response to a visual input; statistical analysis of the magnitude of the steering angle, from subjects performing a tracking task with a steering wheel, shows that the data is consistent with a log-normal distribution. Thus the possibility of modelling human-control...
Heavy-tailed distributions are present in the characterization of different modern systems such as high-resolution imaging, cloud computing, and cognitive radio networks. Commonly, the cumulants of these distributions cannot be defined from a certain order, and this restricts the applicability of traditional methods. To fill this gap, the present letter extends the traditional Edgeworth and Cornish–Fisher...
Power system operation risk assessment can comprehensively take into account the occurrence possibility and severity of disturbances, and it is an effective complement to traditional deterministic security analysis. Calculating transient state probability of components in future short time duration is one of the key issues in power system operation risk assessment. In this paper, a novel probability...
In the Basel II Accord, banks are encouraged to use the Advanced Measurement Approach (AMA), which is suitable for banks to assess operational risk capital, but banks are required to demonstrate their ability to capture severe tail loss events. In this paper, based on the 860 operational risk loss data of Chinese commercial banks collected from public reports from 1995 to 2006, we found that the sample...
This paper developed a hypothesis to overcome the disadvantage of the binary logit model used in resident trip generation. It proposed that random parameters beta' obeyed some distribution firstly. Combined the characters of trip generation and observable variables, it then put forward that beta' followed log normal distribution. The hypothesis was validated by demarcating the parameters in SAS software...
We define a 0Day vulnerability to be any vulnerability, in deployed software, that has been discovered by at least one person but has not yet been publicly announced or patched. These 0Day vulnerabilities are of particular interest when assessing the risk to a system from exploit of vulnerabilities which are not generally known to the public or, most importantly, to the owners of the system. Using...
