The advancement of intelligent car systems in recent years has been significantly influenced by developments in information technology. Driver fatigue is a dominant problem in car accidents. The goal of advanced driving assistance is to develop an advanced driving assistance system (ADAS) a eco-friendly model which focuses on the detection of drowsy driver, to notify drivers of their fatigued condition to prevent accidents on the roads. With relation to driving, the driver mustn’t be distracted by alarms when they are not tired. The answer to this unanswered question is provided by 60- second photograph sequences that were taken when the subject’s face was visible. To reduce false positives, two alternative solutions for determining whether the driver is drowsy have been developed. To extract numerical data from photos and feed it into a fuzzy logic-based system, convolutional network is applied initially; later deep learning technique is followed. The fuzzy logic-based solution avoids the false alarm of the system.

Black box testing plays a crucial role in software development, ensuring system reliability and functionality. However, its effectiveness is often hindered by the sheer volume and complexity of big data, making it difficult to prioritize critical test cases efficiently. Traditional testing methods struggle with scalability, leading to excessive resource consumption and prolonged testing cycles. This study presents an AI-driven test case prioritization (TCP) approach, integrating decision trees and genetic algorithms (GA) to optimize selection, eliminate redundancy, and enhance computational efficiency. Experimental results demonstrate a 96% accuracy rate and a 90% success rate in identifying relevant test cases, significantly improving testing efficiency. These findings contribute to advancing automated software testing methodologies, offering a scalable and efficient solution for handling large-scale, data-intensive testing environments.

Autonomous reconstruction of strip-shredded documents via self-supervised deep learning and global optimization

10.11591/ijra.v15i1.pp107-121
Yi-Chang Wu , Pei-Shan Chiang , Yao-Cheng Liu
Autonomous reconstruction of mechanically shredded documents is a labor-intensive challenge in forensic and archival workflows, particularly for scripts with complex structures such as Simplified Chinese. While traditional manual reassembly is tedious, existing digital tools typically rely on extensive human intervention. This paper presents an automated reassembly framework that integrates a lightweight convolutional feature extractor with global combinatorial optimization. By adapting the established SqueezeNet v1.1 backbone, we employ a task-specific self-supervised learning strategy trained on synthetically shredded samples, enabling the adapted model to capture local stroke continuity and edge-geometry cues without manual annotation. The framework infers pairwise relationships from calibrated edge-region inputs, organizing compatibility scores into an asymmetric traveling salesman problem (ATSP) formulation. The optimal fragment sequence is solved deterministically using the Concorde TSP solver, yielding a globally consistent reconstruction. Experimental results on physically shredded documents demonstrate reconstruction accuracies of 86.5% for Simplified Chinese and 94.8% for Western scripts. These results indicate that the proposed pipeline effectively generalizes from synthetic training data to real-world scenarios, providing a practical, high-throughput foundation for automated document recovery under computational constraints typical of robotic or embedded systems.

10.11591/ijra.v15i1.pp181-189
Pandiyarajan Rajendran , Srinivasan Alavandar
This research presents the conception and building of an inexpensive remotely operated vehicle (ROV) system to ease the tasks of underwater inspection and environmental monitoring in areas where the global positioning system (GPS) signal is not available. A Raspberry Pi-based control unit, an inertial measurement unit (IMU), and depth sensors are merged in the system so that simple data acquisition and remote operation can be carried out. ROV hydrodynamic drag and stability for a state of ideal balance and maneuverability were assessed through tests based on preliminary simulations in Fusion 360 and empirical calculations. The ROV is confirmed to be behaving as expected in terms of stability, imaging capabilities, and responsiveness to operator control in the testing that was done in controlled water environments. This paper, the work, and the testing, in fact, present the initial design, but it is a significant step towards the consideration of the possible further embedding of autonomous features “simultaneous localization and mapping (SLAM)-based navigation, doppler velocity log (DVL), light detection and ranging (LiDAR) systems” for completely autonomous underwater guided missions.

Sentiment aware interactive Chatbot AI using multi agent processing model

10.11591/ijra.v15i1.pp200-209
Vinod Kumar Shukla , Sumithra Alagarsamy , Vijaylakshmi Nagarajan , Gavaskar Shanmugam
Understanding user sentiment has become more important for organizations and consumers due to the rapid growth of social media platforms such as marketplaces, platforms for connecting brands and consumers, and public discussion platforms. Emotions that are based on aspects, nuanced within context, and multifaceted often require complex sentiment analysis algorithms to interpret properly. Furthermore, these systems do not provide real-time information to help companies make better decisions and enhance consumer satisfaction. To tackle these challenges, a novel Interactive Chatbot artificial intelligence (IChat-AI) approach has been proposed in this paper for sentiment-aware chatbot interaction. The word to vector (W2V), term frequency-inverse document frequency (TF-IDF), and bag of words (BoW) are utilized to effectively extract essential features. The deep Kronecker neural network (DKNN) is utilized to predict and classify the emotions into five classes, such as sad, happy, neutral, angry, and fearful. Python has been used to simulate the suggested model. The efficacy of the suggested system is examined employing parameters including recall, execution time, F1-score, complexity, precision, scalability, accuracy, and response time. The developed IChat-AI strategy performs better regarding accuracy than the existing methods, including RoBERTa, TLSA, and multimodal transformers fusion for desire, emotion, and SA (MMTF-DES) approaches, by 5.33%, 4.73%, and 14.39%.

Robotic process automation (RPA) has been deployed in a plethora of industries, including the banking and insurance sectors. However, the key challenge of handling unexpected situations manifests either as an inadequacy of programming (since all situations cannot possibly be foreseen) or incongruous inputs. In parallel, deep learning models, including large language models (LLMs) and visual language models (VLMs), have shown human-like cognitive capabilities in real-world tasks, germinating the field of agentic LLMs. However, their computational expense, slow inference times, and massive energy consumption impede large-scale usage. We propose a framework that combines the two approaches to enable expedient invocation of LLMs for handling exceptions and supervising RPA bots. It aims to minimize the need for human supervision by “meta” automation, while also reducing energy usage and processing time. The automation workflow is presented as a graph, and our pipeline uses the GraphRAG framework to analyze and fix errors. We demonstrate the potential of our pipeline through two real-world examples in the banking and insurance sectors, provide our GitHub repository for reproducibility, and conclude with future research directions.

Diabetic retinopathy (DR) is a major cause of preventable blindness, particularly in areas with limited medical resources where access to ophthalmologists is critical. Existing automated solutions struggle to balance clinical performance, cost-effectiveness, and robustness in the face of fundus image variability—including lighting differences, artifacts, and uneven capture quality. To address this challenge, we propose EdgeRetina, an integrated solution for diabetic retinopathy screening on low-cost mobiles. Our approach combines lightweight preprocessing (128×128 resizing, intensity normalization, and targeted augmentations simulating real-world conditions) with a hybrid SqueezeNet-MobileViT architecture (1.4 million parameters), optimized by dynamic threshold calibration (median: 0.3), maximizing clinical utility. Clinically calibrated INT8 quantization reduces the model to 8.27 MB (-92%) without altering diagnostic performance (sensitivity of 90.7% for referable diabetic retinopathies), while preserving compatibility with floating point 32 (FP32)-based gradient-weighted class activation mapping (Grad-CAM) visualizations. Evaluated on the APTOS 2019 dataset, this solution achieves an AUC of 0.96 with a latency (inference time) of 15.43 ms, reducing CPU consumption by 43% compared to FP32. The dynamic threshold/INT8 coupling decreases false positives by 71.4%. This pipeline thus enables accurate, accessible, and early screening of diabetic retinopathy on low-cost mobile devices, combining operational efficiency and diagnostic reliability in constrained environments, which is crucial to prevent avoidable blindness.

Power system deregulation has made significant changes to the power grid through various technologies, privatization of entities, and improved efficiency and reliability. This work mainly focuses on different combinations of distributed generation (DG) and capacitor banks (CBs) integration to cater to multiple technical, economic, environmental, and reliable concerns. A new optimal planning framework is proposed for optimally allocating the DG units and CBs to achieve multiple objectives. In this work, an augmented objective function is formulated by considering active power losses, voltage deviation, and voltage stability index objectives. This objective function is solved considering various equality and inequality constraints. This work proposes a novel approach for allocation of DGs and CBs in the radial distribution systems (RDSs) using an evolutionary-based self-adaptive firefly algorithm (SAFA). The effectiveness of the developed planning approach is demonstrated on IEEE 33 bus RDS in MATLAB software. The obtained results indicate that proposed planning approach resulted in reduced power losses, voltage deviations, and improved voltage stability.

Motivation could be the greatest currency to succeed in a student’s academic life. This study analyzed academic motivation after students were affected by the pandemic or after their two-year hiatus from active academic face-to-face activities. Moreover, this research examined whether students have influenced academic motivation in terms of gender and degree of program. Using a descriptive-sequential research design, 652 college students at St. Dominic College of Asia, Cavite, Philippines, took part in this study. A survey questionnaire adapted from the academic motivation scale (AMS-C 28) college version was used to determine the level of academic motivation of students. Open-ended questions were provided to the students relating to what motivates them to study and to which students are motivated through techniques during online learning. Findings revealed that the degree of program has a positive effect on student motivation, whereas gender does not significantly associate with motivation. Students showed appreciation for a greater convenience to study because of the technology; however, lack of interaction makes it more challenging for some. Helping students as teachers to keep track of their tasks can make them become great learners and succeed with confidence and determination through their personal and scholarly lives.

Religious commitment, particularly within Islamic contexts, is often viewed as a guiding framework for promoting values such as tolerance, respect, and social harmony; however, differing interpretations and personal expressions of religiosity can sometimes challenge these ideals, necessitating deeper exploration of how religiosity influences social interactions. The study investigates the relationship between religious commitment and respect for others regarding the levels of tolerance behavior among university students. The study employed a descriptive quantitative cross-sectional survey from June 16 to August 16, 2023, with a sample of 334 enrolled in the College of Sharia at Yarmouk University in Jordan. The survey consists of three main scales: religious commitment, respect for others, and tolerance. Students’ demographic data, including gender, nationality, age group, academic department, and the year of study, were also collected via the questionnaire. The findings highlight significant gender differences in religious commitment, with males demonstrating higher levels than females. While no significant age differences were observed in religious commitment, tolerance varied notably, particularly among the 24-26 age group. The study participants represented a diverse range of countries of origin. A country-wise analysis revealed that students from Thailand have the highest religious commitment, underscoring the influence of cultural contexts. Departmental comparisons showed no significant differences, although the findings highlight that respect for others impacts tolerance, religious commitment and demography have almost no effect as predicted. The findings emphasize the primary role of respect in fostering social harmony, suggesting that future interventions should focus on promoting respect as a fundamental value in Islamic culture to enhance tolerance.

This study was conducted to address the critical gaps in financial management practices within Thai public schools, where inefficiencies and mismanagement persist despite available guidelines and funding. The relevance of this research lies in its potential to enhance financial governance, ensuring optimal resource allocation and accountability, which are vital for improving educational outcomes. Employing a mixed-methods approach, the study combined descriptive questionnaires administered to 396 school administrators with structured interviews involving 36 participants to evaluate funding sources, allocation processes, and adherence to financial guidelines. The findings revealed that while schools received funding from diverse sources, namely government, parents, and donors, 85% of administrators reported insufficient budgets. Notably, 82% acknowledged non-compliance with financial guidelines despite submitting utilization reports, highlighting systemic inefficiencies. The study concluded that inadequate financial management skills and inconsistent policy implementation hinder effective resource use. To address these challenges, the study proposes targeted interventions, including specialized training programs, the establishment of dedicated financial departments, and updated management guidelines. These measures aim to strengthen financial accountability and operational efficiency in public schools, offering actionable insights for policymakers and administrators. Future research should compare public and private sector practices to refine standardized financial management frameworks.

This study explores how educators and students in Philippine secondary schools conceptualize global citizenship education (GCE) and understand their roles in advancing the sustainable development goals (SDGs). Despite its prominence in global education agendas, GCE remains inconsistently understood across local contexts. Using a qualitative research design, in-depth interviews were conducted with 21 teachers and students in Surigao del Sur. Thematic analysis revealed seven interconnected themes: i) holistic education: framing global citizenship beyond academics; ii) cultural sensitivity and respect for diversity; iii) active engagement and global awareness; iv) education as a channel for sustainable development; v) becoming a global citizen as a personal journey; vi) technology and global connectivity; and vii) teaching values for global responsibility. Findings indicate that while both groups support GCE, their interpretations are shaped by lived experiences, institutional conditions, and cultural environments. Teachers highlighted intentional instruction and moral formation, whereas students emphasized identity development, participation, and global awareness. However, gaps remain in critical reflection and structural understanding. In response, this study introduces the contextualized empowerment framework, a strategic model that integrates civic action, values, identity, and digital literacy to guide localized and ethical implementation of GCE. The framework offers actionable insights for curriculum development, teacher training, and educational policy reforms.

This study investigates the relationship between student motivation and self-regulated learning strategies among Malaysian boarding school students, using self-determination theory (SDT) as its theoretical foundation. A total of 328 form four students from four northern Malaysian boarding schools participated. Using a validated version of the motivated strategies for learning questionnaire (MSLQ) and analyzed through second-order partial least squares structural equation modeling (PLS-SEM), results revealed a significant positive relationship between motivational beliefs, especially self-efficacy and intrinsic value, and self-regulated learning strategies. The study’s novelty lies in validating a culturally adapted, second-order motivation model tailored to Malaysian boarding schools. Notably, the research isolates the mediating effect of intrinsic motivation on self-regulation within a high-pressure, collectivist setting, extending SDT’s applicability. However, limitations lie in the use of a cross-sectional design and dependence on self-reported data, and regional focus. Future studies should adopt longitudinal designs, consider diverse school types, and integrate perspectives from teachers or parents to strengthen validity. Including objective academic performance metrics may offer deeper insight. This research affirms the relevance of SDT in Malaysia’s education system and provides a validated framework linking motivation to strategic learning. The findings support evidence-based pedagogical strategies and align with sustainable development goal (SDG) 4 on quality education and goal 10 on reduced inequalities, promoting for fair and motivation-enhancing environments of learning.
