An Efficient Approach to EEG-Based Emotion Recognition using LSTM Network

Abstract: This work aims to investigate the performance of the Long Short-Term Memory (LSTM) Model for EEG-Based Emotion Recognition. For the experimentation, we use the publicly available DEAP dataset, which consists of preprocessed EEG and physiological signals. Our work limits itself to the study of only the EEG signals to have a scope for developing an efficient headgear model for real-time monitoring of emotions. In this study, we extract the band power, a frequency-domain feature, from the EEG signals and compare the classification accuracies for Valence and Arousal domain for different classifiers. The proposed Long Short-Term Memory (LSTM) model achieves the best classification accuracy of 94.69% and 93.13% for Valence and Arousal scales, respectively, illustrating a significant average increment of 16% in valence and 18% in arousal in comparison to other classifiers.

Mechanical and wear performance of Al/SiC surface composite prepared through friction stir processing

Abstract: In the present research work, AA7075 composite reinforced with silicon carbide particles has been fabricated using Friction stir processing (FSP). The silicon carbide particles having a size of 40 μm were placed in grooves of length 160 mm, width 2 mm, depth 3.5 mm, that were generated on the AA7075 plate. The square pin tool is utilized for fabricating the composite at two different rotational speed i.e. 700 and 1000 rpm. Effect of processing, particle addition and tool rotational speed is analyzed on mechanical and wear properties of the material. On friction stir processing the microhardness value and elongation of the material increased. Reinforcement addition contributed to decrease in ductility and tensile strength while on the contrary microhardness and wear resistance of the material improved. Tool rotational speed showed a direct relation with the tested mechanical and wear properties. Adhesive wear was the prominent wear mechanism and Fe layer formation was observed on the worn surface, contributing to increased wear resistance. These fabricated composites can find vast application in industries like automotive, defence and aerospace.
