Using the Muse II headband, we obtained EEG data across 5 channels from 34 participants aged 16-25, comprising 32 males and 2 females, with backgrounds as high school students, undergraduates, and employees. EEG data collection took place in a suitable environment, characterized by a comfortable and interference-free setting optimized for interviews. The research contribution is the creation of a lie detection dataset and the development of an autoencoder model for feature extraction and a deep neural network for classification. Data preparation involved several pre-processing steps: converting microvolts to volts, filtering with a band-pass filter (3-30Hz), STFT transformation with a 256 data window and 128 overlap, data normalization using z-score, and generating spectrograms from power density spectra below 60Hz. Feature extraction was performed using an autoencoder, followed by classification with a deep neural network. Methods included testing three autoencoder models with varying latent space sizes and two types of classifiers: three new deep neural network models, including LSTM, and six models using pre-trained ResNet50 and EfficientNetV2-S, some with attention layers. Data was split into 75% for training, 10% for validation, and 15% for testing. Results showed that the best model, using autoencoder with latent space size of 64x10x51 and classifier using the pre-trained EfficientNetV2-S, achieved 97% accuracy on the training set, 72% on the validation set, and 71% on the testing set. Testing data resulted in an F1-score of 0.73, accuracy of 0.71, precision of 0.68, and recall of 0.78. The novelty of this research includes the use of a cost-effective EEG reader with minimal electrodes, exploration of single and 3-dimensional autoencoders, and both non-pretrained classifiers (LSTM, 2D convolution, and fully connected layers) and pretrained models incorporating attention layers

Theoretical and Experimental Investigation of the Effect of Linear Fluid Power Control System Design on its Static and Dynamic Performance
Get PDFFluid power control systems are widely used in automated systems like manufacturing, biomedical treatments, and food handling, as well as in optimizing aircraft wing design, mobile applications, and thermal management in electronic devices, energy transformation, and aerospace applications. This study investigated the static and dynamic characteristics of a linear fluid power control system utilizing either a servo control valve (SV) or a proportional directional flow control valve (PV). The study focused on evaluating performance differences between these two valve types while maintaining a constant oil temperature at 30°C. Experimental tests were conducted under varying supply pressures, loads, and valve types. A system was built to conduct real-time experiments. In this paper we studied the effect of valve flow rate at full opening, the actual supply pressure-decay, and studied the effect of the loading system on the performance. The aim of this paper is to find out which control valve is better in static and dynamic performance in real-world. Through comparing two hydraulic control valves designs, the experiment results show that the servo control valve (SV) offers a clear advantage over the proportional directional flow control valve (PV) in linear fluid power control systems operating at a constant temperature. The SV designs demonstrated superior performance in terms of flow rate, pressure retention, and dynamic response. This makes SV an optimal choice for applications requiring high flow rates, consistent pressure, and precise, rapid adjustments, especially in high-speed operations
Exploring the impact of English song listening habits on listening proficiency
Get PDFThis study examines the correlation between the listening proficiency of third-semester English Education students at a private university in Indonesia and their habits of listening to English songs. Data collection involved a questionnaire designed to gauge students' frequency and genre preferences in listening to English music alongside Mid-Term Examination (UTS) scores used to indicate their listening proficiency. A Lilliefors normality test was conducted on the data related to students' listening skills and their song-listening habits, yielding significant values of 0.020 and 0.200, respectively. The null hypothesis (H0), which assumes that the data follows a normal distribution, was considered in this context. The Spearman’s rho correlation test, a non-parametric measure for determining the direction and strength of the association between two variables, revealed a correlation coefficient of -0.125 between students' listening proficiency and their English song-listening habits. The negative coefficient suggests a weak negative correlation between these variables. However, careful interpretation of this coefficient, including its associated two-tailed p-value, is necessary to determine the statistical significance of the observed relationship. The weak negative correlation observed indicates that listening to English songs as a habit may not substantially enhance listening proficiency in academic contexts. This finding suggests that while exposure to English music may offer informal language exposure, it may not directly translate into improved academic listening skills. Consequently, educators and curriculum developers should consider supplementing informal listening practices with structured listening exercises specifically tailored to students' linguistic and comprehension needs. This study underscores the need for a more comprehensive approach to developing listening skills within English language education
