Child safety and well-being in daycare settings are important, thus it is vital that the persons in charge be attentive to them. This research tries to solve the problem by introducing a smart and detailed monitoring system that utilizes new technology to enhance safety and support caretakers. The system has various innovative features, such as child missing detection, behavior and facial expression analysis, cry analysis and categorization, and fall detection. Using high-resolution cameras and on-device Edge AI capabilities, it ensures real-time surveillance of children's activities while protecting privacy. The approach integrates behavior and facial expression analysis to assess emotional states, cry recognition to discover childcare needs, as well as a useful fall detection system that can tell the difference between falls and other movements. All these parts synergize to hand over the necessary information to the caregivers on time and in a way that they can act upon. The quantitative experiments in real-time childcare centers show high accuracy through all the components, attesting to the system's reliability and durability. This research has important significance in improving the safety and the frequency response in daycare centers because it gives caregivers automated tools to quickly address the needs of children. While promising, the system has drawbacks, such as potential biases in data models and a reliance on ideal environmental circumstances. Future work intends to improve flexibility across varied daycare situations, improve accuracy through larger datasets, and investigate ethical frameworks for wider application. © 2024 IEEE.

Bidirectional user interfaces serve more than half a billion users worldwide. Despite increasing diversity-driven approaches to interface development, bidirectional interfaces still use UI items' directionality inconsistently and incorrectly. Designers should pay special attention to UI items containing ambiguous information that can be processed both from right to left and from left to right by bidirectional users. Such items are susceptible to ineffective use. This paper reports preliminary results from a study with 1705 Arabic and Hebrew users. We investigated the directional interpretation of 16 UI items, empirically demonstrating the ambiguity problem in bidirectional interfaces and the potential influence of UI factors on how users interpret the items' directionality. While the study indicates that preventing all interpretation errors is unlikely, a large portion of those errors can be addressed by proper design. © 2023 Owner/Author.

Graph clustering is a powerful technique used to identify and group similar nodes within a complex network structure. This procedure involves segmenting the graph into distinct groups, with the nodes in each group having strong interconnections or similar characteristics. In this survey, we will highlight a variety of existing approaches of graph clustering, including spectral clustering, modularity optimization and hierarchical clustering, to efficiently discover meaningful clusters, facilitating analysis and decision-making in diverse fields ranging from data science and network analysis to social sciences and bioinformatics. © 2023 IEEE.

With the rapid development of computer vision and deep learning technologies, object detection plays a crucial role in various fields. Due to the complexity and diversity of underwater environments, underwater vision tasks face great challenges. In this paper, we improved the YOLOv8 detection model for the fish detection task in complex environments. Specifically, we proposed a multi-scale feature fusion method (MFANet) that combines multiscale weighted feature fusion with multiscale attention to efficiently capture multilevel features of fishes in complex environments. We designed a multiscale weighted feature fusion module that combines feature maps at different scales to enhance the model's representation of the target. By introducing a multi-scale attention mechanism, the model is able to pay more attention to important feature regions. We conducted experiments on real underwater complex environment datasets. The results show that our proposed improved method significantly enhances the performance of the YOLOv8 model in fish detection tasks and lays a good foundation for subsequent underwater detection tasks. © 2024 IEEE.

Nowadays face recognition methods are in great interest of computer vision area. The development of a face recognition method that provides a high level of reliability of the solution in the absence of restrictions on the source image is a very crucial task. The paper deals with analysis of existing algorithms for recognizing the geometric characteristics of the face. As a result a combined method for identifying the face was developed. The main goal of this paper is to develop methods for recognizing and detecting faces that increase the reliability of identification of objects of analysis, reduce the level of false recognition, reduce the training time of the classifier and the time of preliminary processing and recognition of the image. © 2023 IEEE.

This research concentrates on author profiling using transfer learning models for classifying age and gender. The investigation encompassed a diverse set of transfer learning techniques, including Roberta, BERT, ALBERT, Distil BERT, Distil Roberta, ELECTRA, and XLNet. Through meticulous evaluation using metrics such as the Matthews Correlation Coefficient, Accuracy, Precision, Recall, and F1 Score, the study examined the efficacy of these models. The curated dataset was divided for gender and age tasks, resulting in robust gender prediction with the XLNet model and age prediction with the BERT model. Notably, the XLNet model achieved the highest MCC (0.7946), Accuracy (0.8957), Precision (0.8992), Recall (0.8957), and F1 Score (0.8958) values in gender classification, while the BERT model excelled in age prediction with an MCC of (0.7338), Accuracy of (0.8220), Precision of (0.8324), Recall of (0.8220), and F1 Score of (0.8243). Visualized outcomes provide valuable insights into the model’s performance nuances, paving the way for their practical implementation. This research offers novel contributions to author profiling tasks, bridging the gap between theory and real-world applications. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

In the present era, e-government portals are viewed as an effective means of providing online services to citizens. It is imperative for everyone to guarantee equitable access to these services, irrespective of their abilities or limitations. Hence, accessibility is vital for those with disabilities and advantageous for everyone. Web Content Accessibility Guidelines (WCAG) provide a comprehensive set of guidelines, in terms of success criteria, that are widely utilized in various tools to assess the accessibility of websites or portals. By following these guidelines, developers can ensure that their websites are accessible to everyone. This paper reports on a study of the accessibility evaluation of five Moroccan e-government portals using the AChecker tool with respect to WCAG. The aim was to prepare recommendations to improve the overall user experience across Moroccan e-government portals. The evaluation results analysis showed that the portals have some common as well as different failed success criteria with different numbers of errors per WCAG principle and conformance level. In particular, all the portals exhibited varying degrees of adherence to the four principles, and most of the portals struggled to meet levels A and AA, and none of them achieve perfect conformance across all levels. To address this issue, a set of recommendations is provided for each portal to enhance accessibility. The lessons learned from this study can contribute to more inclusive e-government portals and provide insights for governments and designers to prioritize accessibility enhancements. © 2024 Copyright for this paper by its authors.
