This study was an attempt to recognize the effect of a humorous audio-visual stimulus on the autonomic nervous system (ANS) and the heart physiology of females. Electrocardiogram (ECG) signals were acquired from eleven female volunteers under pre- and post-stimulus conditions. Heart rate variability (HRV) and time-domain ECG analyses were performed to non-invasively realize the effect of the humorous...
In recent years, the development of EMG-based assistive technologies has received special attention of the researchers. This can be attributed to the advantages of EMG signal over other biosignals. The present study proposes the development of a dual-channel EMG biopotential amplifier. The biopotential amplifier was designed using INA128 instrumentation amplifier and was used for acquiring EMG signals...
The proposed research focuses on designing a low-cost electromyogram (EMG) data acquisition system (DAQ). The developed system acquires EMG signals from the sub-vocal region and suitable features are extracted using time-frequency transform such as Wavelet Transform. Once the features are extracted, the final classification is carried out using ensemble decision trees called Random Forests (RF). Giving...
In the present study, attempts were made to classify menstrual phases of young healthy female (21–25 years) based on the features obtained from ECG signals. Statistical features were extracted from the heart rate variability (HRV) and the ECG signals and were used for pattern recognition during the different menstrual phases. The pattern recognition studies using HRV features suggested that the menstrual...
