The analysis on the online finger gesture recognition using multi-channel sEMG signals was explored in this paper. Nine types of gestures were applied to be identified, involving six kinds of numerical finger gestures and three kinds of hand gestures. The time domain parameters were extracted to be the features. And then, the probabilistic neural network was utilized to classify the proposed gestures with the extracted features. The experimental results showed that most of gestures could acquire the acceptable classification performance and a few elaborate gestures were hard to acquire the effective identification.
In this paper, Let R is
a ring, G be a finite
group of ring automorphisms of R. R*G denote the skew group ring of R under G. We
investigate the right p.q.-Baer property of skew group rings under finite group
action, Assume that R is
a semiprime ring with a finite group G of X-outer ring automorphisms of R, then 1) R*G is p.q.-Baer if and only if R is G-p.q.-Baer; 2) if R is
p.q.-Baer, then R*G is p.q.-Baer.
This study is aimed to validate the extraction process of Isatis Radix.
Using near infrared spectroscopy and high performance liquid chromatography to
determine the uridine, adenosine, guanosine contents in Isatis Radix Solution,
as well as NIR to monitor the extraction process. The results indicate that the
existing extraction is optimized to extract thoroughly.
This paper studies the method for measuring
the loop resistance of GIS conductor pole based on the super capacitor
producing impulse current up to several thousand amperes. This method overcomes
the limitations of conventional diagnostic method. Typical GIS conductor poles
are chosen. Based on FEA and lab tests, the effect of different forms of
current and contact condition, relationship between the temperature of contact
and the loop resistance is researched. In full- scale testing under realistic
operating conditions on the new 220 kV GIS using prototype instrumentation a very
good sensitivity in an early stage was obtained.
