Computer forensics is the crucial technology against computer crimes. However, existing forensics methods or technology are inefficient and their stringencies are poor. This paper proposed a novel dynamic computer forensics model (DAIP) based on artificial immune and real-time network fatalness, which can vivify the crime scene. The definitions of self, non-self, and immunocyte in the network transactions...
Previous research on facial expression recognition mainly focuses on near frontal face images, while in realistic interactive scenarios, the interested subjects may appear in arbitrary non-frontal poses. In this paper, we propose a framework to recognize six prototypical facial expressions, namely, anger, disgust, fear, joy, sadness and surprise, in an arbitrary head pose. We build a multi-pose training...
In this paper, a silicon matrix detector is described and the results of the cosmic ray test are given. The silicon matrix is composed by the 180 silicon PIN detectors, which covers an area of 32 * 20cm2. The data of whole detectors is read out by the ASIC chips, and suppressed by an FPGA. In the test system, the trigger is given by two plastic scintillators, which are placed above and beneath the...
