Most developments of the sequential probability ratio test (SPRT) control chart assume that the underlying process comes from a Normal distribution with known mean and standard deviation. Nevertheless, the true values of the process parameters are usually inaccessible in production settings, and they must be approximated from a set of Phase-I data. In certain areas, the process data can be positively skewed, which in turn affect the performance of control charts designed under the Normal distribution. In this paper, we provide a thorough analysis on the performances of the SPRT chart with estimated process parameters under the influence of Weibull distributed data. The unconditional properties of the expected value and standard deviation of the time to signal are evaluated using Monte Carlo simulation to facilitate comparisons between the Normal and Weibull distributions. Results show that both the in-control and out-of-control performances of the SPRT chart deteriorate when Weibull data are used. However, the optimal design of the SPRT chart with estimated process parameters seems to reverse the effect for large process mean shifts.

This study presents an emotion detection system utilizing Electroencephalogram (EEG) data, integrated into the home robot's human-robot interaction model. With advancements in affective computing technology, the demand for home robots has been on the rise, offering emotional support and companionship through emotion recognition and responses, significantly enhancing the user experience. Leveraging the DEAP dataset, this study achieved real-time recognition of users' emotional stales through preprocessing, feature extraction, and classification model training. We downsampled, removed artifacts from, and filtered the raw EEG signals, extracting features from the frequency, time, spatial domains, and brain networks. LASSO regression was employed for feature selection, followed by the application of various machine learning algorithms for emotion classification. The experimental results showed that the KNN classifier performed best in emotion recognition, achieving an average accuracy of 90.3%. Further human-robot interaction tests validated the system's practical applicability, with participants rating highly the precision of emotion detection, the timeliness of interactive responses, and the overall experience. The proposed EEG-based emotion recognition system shows significant potential in enhancing the human-robot interaction experience for home robots, while also suggesting directions for further improvements in real-time performance and personalized models.

In this study,a frequency-reconfigurable microstrip patch antenna that has a central slot and RF MEMS shunt switches is optimized and improved. The substrate material for the investigation was chosen to be FR4 epoxy, with dimensions of 40 mm by 65 mm and 1.6 mm for height. The measurements of the microstrip patch were found to be 19.5 mm by 31 mm, and the feed dimension was 16.4 mm by 1.3 mm. After preliminary research, a center slot was added and slots were added on both sides of the patch to accommodate RF MEMS switches. In order to maximize the antenna's performance, parametric analysis was carried out, which involved making iterative changes to the patch dimensions and slot characteristics. Notably, the improved antenna configuration produced a gain of 5.1 dBi and a VSWR of 1, making it appropriate for 3.5 GHz applications such as wireless local area networks (WLANs), mobile phones, and radar systems. The outcomes show how well the suggested design strategy works to improve antenna performance for real-world implementation in modern communication systems.

Autonomous navigation of a robot in agricultural fields is essential for every task from crop monitoring to weed management and fertilizer application. Many current approaches rely on accurate GPS, however, such technology is expensive and can be impacted by lack of coverage. As such, autonomous navigation through sensors that can interpret their environment (such as cameras) is important to achieve the goal of autonomy in agriculture. In this paper, we introduce a purely vision-based navigation scheme that is able to reliably guide the robot through row-crop fields using computer vision and signalprocessing techniques without manual intervention. Independent of any global localization or mapping, this approach is able to accurately follow the crop-rows and switch between the rows, only using onboard cameras. The proposed navigation scheme can be deployed in a wide range of fields with different canopy shapes in various growth stages, creating a crop agnostic navigation approach. This was completed under various illumination conditions using simulated and real fields where we achieve an average navigation accuracy of 3.82cm with minimal human intervention (hyper-parameter tuning) on BonnBot-I.
