The highway infrastructure traffic safety performance evaluation is unstable and unreliable based on the traffic accident number or rate directly as well as other non-accident method. The principle of traffic accident spatial distribution along a highway and correlation between highway traffic safety performance and accidents positions for a period of time were researched. An accident aggregation...
With China's rapid economic development, the strong electricity demand, power shortages have become a major economic and social development factors, so that sustainable economic development of China's power has increasingly become the focus of attention. Sustainable development of circular economy is in line with the strategic situation requires the product of human society and economic system structure...
Improving safety on the road is one of the most challenging goals of recent investigations in VANETs (Vehicular Ad-hoc Networks). CCA (Chain Collision Avoidance) applications are a new emerging means of reducing the number of accidents on the road by providing cars with collaborative communication capabilities, thus allowing them to react against the real risk of accident which may occur in different...
High ratio adverse events in surgery of interlocking intramedullary nails (IINs), especially in the distal locking operation have been the major issues troubling the surgeons. An ergonomics method which is the HTA method based on the SRK mode is proposed to improve the performance of IINs, and a seven-step procedure of this method is adopt to carry out the analysis. Two parameters which are the requirements...
It is often difficult to estimate exact probabilities of occurrence of fault events for the use in the conventional fault tree analysis (FTA) when failure data are insufficient or fault events are vague such as human error. A hybrid approach utilizing fuzzy sets and possibility theory is presented to overcome this problem. In the approach, failure possibilities of imprecise events are characterized...
The challenge of this work is to study the design and development of human-robot collaboration (HRC) in cellular manufacturing. Based on the concept of human collaborative design, four main design factors are being identified and developed in an active HRC prototype production cell for cable harness assembly. Human collaborative design aims to optimize the system design for the advantage of collaboration...
A direct teaching system emphasizing safety and operability for SP02, an upper-body humanoid that cooperates with a human in a cell-production workspace has been described. The system has a direct teaching device, which enables an operator to teach a multi-D.O.F manipulator at comfortable posture despite large changes in the pose of an end-effector. The double-checked safety-related part (SRP/CS)...
The purpose of this study was to develop a robotic endoscope that is low invasive, easy to operate and capable of locomotion from the rectum to the appendix in the human body. We believe that it would contribute to relieving pain in patients. We therefore developed a robotic endoscope that consists of a front and rear body with clockwise and anticlockwise helical fins, respectively. The front and...
