Myoelectric pattern-recognition techniques have been developed to infer user's intention of performing different functional movements. Thus electromyogram (EMG) can be used as control signals assisted devices for people with disabilities. Pattern-recognition-based myoelectric systems rarely designed stroke survivors. Aiming at developing such a system improved rehabilitation, this study assessed detection the affected limb's movement using high-density surface EMG recording and techniques....
Anaerobic and aerobic treatment of high-strength pharmaceutical wastewater was evaluated in this study. A batch test performed to study the biodegradability wastewater, result indicated that a combination anaerobic-aerobic system effective removing organic matter from wastewater. Based on test, pilot-scale composed an anaerobic baffled reactor followed by biofilm airlift suspension designed. At stable operational period, effluent chemical oxygen demand (COD) ranged 1,432 2,397mg∕L at...
Abstract Background The number grain per panicle of rice is an important phenotypic trait and a significant index for variety screening cultivation management. methods that are currently used to count the grains manually conducted, making them labor intensive time consuming. Existing image-based counting had difficulty in separating overlapped grains. Results In this study, we aimed develop image analysis-based method quickly quantify panicle. We compared accuracy several among different...
ZiYuan-3 (ZY-3) surveying satellite is China's first civilian high-resolution stereo mapping satellite. The satellite's objective oriented towards plotting 1:50,000 and 1:25,000 topographic maps. Compared with using foreign commercial imagery, establishment of the image geometry model core technical problem for different products various applications ZY-3 This article analyses key problems high-precision processing based on overall design, proposes technology virtual CCD line-array imaging....
ABSTRACT The development philosophy of water resources spatial equilibrium (WRSE) is a crucial aspect China's conservancy strategy. To quantitatively evaluate the WRSE in Chongqing and diagnose obstacle indicators, evaluation diagnostic model was proposed based on coupling coordination degree subtraction set pair potential (SSPP) from both supply demand perspectives. results showed that economically developed regions were suffering scarcity disequilibrium. state excellent to poor city...
The Ziyuan-3 (ZY-3) satellite was designed to satisfy 1:50000 scale mapping requirements. This study uses 556 images obtained by ZY-3, from June 1 October 31, 2013, covering an area of 3 500 000 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in midwestern China. A total 900 check points measured a global positioning system were also used conduct the planar accuracy verification. experimental results show that ZY-3 nadir sensor...
The Luojia 1-01 Satellite (LJ1-01) is the first professional night-light remote-sensing satellite in China, and thus, it of pioneering significance for development remote sensing satellites China application social economic fields.
