Platycodon grandiflorum (PG) is extensively used for treating cough, excessive phlegm, sore throat, bronchitis and asthma, whereas Adenophora stricta (AS) is commonly used to reduce phlegm, clear lung and tonify stomach. Due to similar appearances, PG is sometimes adulterated with cheap AS so as to gain profits. And this will inevitably result in different(More)
The Multiple Field-of-view Navigation System (MFNS) is a spacecraft subsystem built to realize the autonomous navigation of the Spacecraft Inside Tiangong Space Station. This paper introduces the basics of the MFNS, including its architecture, mathematical model and analysis, and numerical simulation of system errors. According to the performance(More)
Robust and automatic diagnosis of the mechanical dyssynchrony for the left ventricle is essential for the cardiac resynchronization therapy. However, no existing method could meet the desired accuracy yet. In this paper, a new approach is proposed for auto-diagnosis of the intraventricular mechanical dyssynchrony of the left ventricle based on a series of(More)
Stripe extraction methods are a fundamental step for the structured light three-dimensional measurement systems. This work proposes an efficient and robust stripe extraction method for structured light measurement system. In this paper, a novel method for extracting the stripes from structured laser lights is presented which is based on the Steger stripe(More)
3D measurement technology is one of the important research fields in computer vision. 3D measurement based on binocular stereo vision is a typical measurement technique. In this paper, the structured light technology is combined with binocular stereo technology. The structured light can increase the feature of object's surface, so we can reconstruct the(More)
A mesophilic, Gram-negative, arsenite[As(III)]-oxidizing and arsenate[As(V)]-reducing bacterial strain, Pseudomonas sp. HN-2, was isolated from an As-contaminated soil. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that the strain was closely related to Pseudomonas stutzeri. Under aerobic conditions, this strain oxidized 92.0%(More)
