BACKGROUND The decreasing suicide rate in China has been regarded as a major contributor to the decline of global suicide rate in the past decade. However, previous estimations on China's suicide rates might not be accurate, since often they were based on the data from the Ministry of Health's Vital Registration ("MOH-VR") System, which is biased towards the better-off population. This study ai...

Product disassembly and recycling are important issues in green design. Disassembly sequence planning (DSP) is an problem the product process. The core idea to generate best or approximately optimal reduce costs time. According characteristics of DSP problem, a new algorithm solve proposed. Firstly, hybrid graph introduced, constraint matrix established. Secondly, disassembling time, replacemen...

This paper introduces a reference-pulse interpolator motion control system, which can be applied for computer numerical control (CNC) machine tools. The interpolation is calculated in DSP and the independent pulse generator modules are performed in FPGA, which can generate precise reference velocity profile and eliminate the path error of reference pulse interpolation. The proposed methodology ...
