The frequent emergencies have inflicted the huge casualties and property losses. In the recent years, the casualty prediction models which some domestic scholars have established are mostly consist of a single factor or a small number of factors. In this paper, multi-output support vector regression is applied to respectively predict personnel mortality and injury rates on the former and the basis...
Sealed storage and access control are the characteristics of USB KEY integrated with smart card, a kind of USB KEY-based approach for virtual assets protection is presented. Virtual assets of users are stored in the hidden partition of USB KEY which is not able to read out, it would be displayed on the screen of USB KEY after user's PIN verified. If a PIN is blocked, it must be reloaded, it is designed...
Autonomous navigation in cross-country environments presents many new challenges including obstacle perception for Unmanned Ground Vehicle. This paper proposes new method that is suitable for distributing Basic Probability Assignment (BPA), based on which D-S theory of evidence is employed to integrate sensors information and recognize the obstacle. Firstly, select the experiment formula, then by...
Efficiently and accurately detecting pedestrian plays a very important role in many computer vision applications such as Intelligent Transportation System and Safety Driving Assistant. This paper puts forwards a two-stage pedestrian detection method based on machine vision. Firstly, the expanded Haar-like characteristic is selected and calculated using integral map and the pedestrian detection cascaded...
Intelligent vehicle navigation in complex cross-country terrain can benefit from accurate obstacle avoidance path-planning. The paper presents an obstacle avoidance path-planning algorithm based on stereo vision system. Firstly, Multi-feature extraction based stereo matching techniques is proposed on a corner and edge extracted image pair to accomplish environmental perception, which can provide robust...
The structures of multi-wall carbon nanotubes (MWNTs) were modified by H 2 SO 4 –HNO 3 and H 2 SO 4 –H 2 O 2 , respectively. The corresponding products were water-soluble MWNTs-A and MWNTs-B. According to the experiment, it was found that MWNTs-B could emit stable solid substrate-room temperature phosphorescence (RTP) on the surface of paper...
