Background Sufficient decompression of the nerve root canal is still regarded as the method of choice when operating on patients with lumbar disc herniation (LDH) with lumbar lateral recess stenosis; however, tissue-sparing procedures are becoming more popular. Endoscopic techniques offer advantages and the benefits of rehabilitation, which have become the standard in many surgical operations when...
Adjustable autonomy is an important mechanism in advanced robotic system. With this mechanism, robot can cooperate with operators, and the efficiency of mission is improved. In order to evaluate the advantages of the adjustable autonomy mechanism, a method of evaluating autonomous performance of Unmanned Surface Vehicle (USV) is proposed. This method considers two aspects in navigation task: the effectiveness...
Nanoporous carbonaceous materials with high surface area were prepared by the pyrolysis of polymethyl (phenyl) siloxane resin (SR249) under vacuum at a controlled temperature (1250–1350°C) followed by leaching in hydrofluoric acid (HF). Their compositions and structures at different pyrolysis temperatures were investigated by X-ray diffraction, Raman spectroscopy, elemental analysis, transmission...
Nanoporous carbonaceous materials with high surface area were prepared by the pyrolysis of polymethyl(phenyl)siloxane resin (SR249) under vacuum at a controlled temperature (1 250 °C–1 350 °C) followed by leaching in hydrofluoric acid (HF). Their compositions and structures at different pyrolysis temperatures were investigated by X-ray diffraction, Raman spectroscopy, elemental analysis, transmission...
