In this paper, we propose a novel patient-specific electrocardiogram (ECG) classification algorithm based on the recurrent neural networks (RNN) and density based clustering technique. We use RNN to learn time correlation among ECG signal points and to classify ECG beats with different heart rates. Morphology information including the present beat and the T wave of former beat is fed into RNN to learn...
Over the last 20 years, China has successfully established a modern biotechnology industry from almost nothing. Presently, China is a major producer of a vast array of products involving bioprocesses, for some China is even the world’s top producer. The ever-increasing list of products includes organic acids, amino acids, antibiotics, solvents, chiral chemicals, biopesticides, and biopolymers. Herein,...
Indoor environment is tightly related to the life of human beings. Urban residents spend over 90% of their daily time in indoor environments, among which over 50% is in residential environment. Therefore, the indoor air quality (IAQ) in residential environment will influence residents' health and safety directly. How to appraise the risk of residential indoor environment quality and to create a comfortable...
Application of hot stamping technology of advanced high strength steel is one of the effective approaches for automotive light-weighting. It is important to investigate the effects of hot stamping process parameters on forming quality for the application of hot stamping technology. A kind of hot stamping tool system for process tests of U-shape sample is introduced. It includes cooling system and...
The material parameters of Chaboche nonlinear isotropic/kinematic hardening rule were identified based on the stress-stain curve of DP600 and Hill'48 yielding criterion. A FEM model was established in ABAQUS to investigate effect of different hardening rules on springback prediction for an open-channel shaped part. According to the FEM results, the prediction based on Chaboche nonlinear isotropic/kinematic...
