Emotion influences human health significantly. In this pilot study, a movie clips method has been designed to induce 5 kinds of emotion states. 90-sec corresponding ECG signal have measured in the end video stimulus. Heart rate variability (HRV) features were extracted from by using time-domain, frequency-domain, Poincare, and statistic analysis. Then these HRV used classify different states support vectors machine (SVM). Also, we principal component analysis (PCA) reduce number features....

Changing the whole network into a software defined (SDN) is impractical due to high replacement cost. Therefore, there exist SDN hybrid networks, where switches and legacy coexist at same time. In this paper, we propose an architecture which can discover existence of by using Spanning Tree Protocol thus have global view network. We also enable OpenFlow cooperate with Learning Bridge without requiring any modification on switches. By utilizing characteristics SDN, applications dynamically...
