Depression is a mental disorder characterized by persistent occurrences of lower mood states in the affected person. According to the study of World Health Organization (WHO), depression will become the second largest cause of illness threatening the life of human beings in 2020, so early detection, early diagnosis and early treatment of depression is very important to save the health and life of...
Recently, Electroencephalogram (EEG) has become increasingly important in the role of psychiatric diagnosis and emotion recognition. However, many irrelevant features make it difficult to identify patterns accurately. Obtaining valid features from electroencephalogram can improve the classification and generalization performance. In this paper, an improved normalized mutual information feature selection...
Ejected plasma used in gas spark switch has been proved efficient as a trigger method. However, the development and trigger mechanism are still to be revealed. In this paper, an experimental platform was built to investigate the influence of trigger pulse energy and polarity on the space-time shape evolution characteristics and the ejecting characteristic of ejected plasma. The results indicate that...
In this paper, a dual-electrode gas switch triggered by ejected plasma is proposed to ensure the switch to be triggered reliably under extremely low switching coefficient. The switch has the configuration of dual electrodes, in one of which a microincentive chamber is embedded to develop ejected plasma into the switch gap, leading to the breakdown of the switch. Both the features of ejected plasma...
Digital microfluidic biochip (DMFB) is an attractive platform for immunoassays, point-of-care clinical diagnostics, DNA sequencing, and other laboratory procedures in laboratory experiments due to its flexible application and low fabrication cost and further for the development of instruments. As being applied for these safe-critical applications, on-line testing methods are required to ensure robust...
