Abstract: Stone crusher sites commonly depend on manual supervision, physical registers and reactive security measures, which can lead to theft of equipment or raw material, delayed response to unauthorized movement, incomplete operational records and avoidable downtime. The Automation of Stone Crusher Management System (ASCMS) presented in the attached study is an intelligent automation framework designed to address these problems through integrated IoT sensing, AI-enabled surveillance, real-time dashboards and centralized software control. This professional research paper reorganizes the supplied work into a structured manuscript and presents the system objective, methodology, architecture, implementation process and reported results in a clear academic format. The system uses multiple input sources, including surveillance cameras, RFID and motion sensors, and manual operational inputs. These inputs are processed through a centralized software layer that performs data integration, analytics, machine-learning-based anomaly detection, decision support and alert generation. The output layer provides live dashboards, automated notifications, reports and optimization recommendations. The source results indicate that ASCMS improves security, reduces unauthorized incidents, automates operational logging, supports real-time monitoring and remains scalable for broader industrial applications. The incident comparison reported in the source shows a reduction from 18 theft or intrusion events before implementation to 4 events after ASCMS deployment. Overall, the work demonstrates that a layered AI-IoT architecture can improve safety, accountability and operational efficiency in stone crusher management when it is supported by careful hardware integration, software validation, security testing and continuous feedback-based optimization.

Abstract: Background: Artificial intelligence (AI) technologies are increasingly integrated into educational settings to enhance student engagement and classroom interaction. However, the evidence base regarding their effectiveness remains fragmented. This systematic review synthesizes empirical evidence on the role of AI in improving student engagement and classroom interaction in K-12 and higher education contexts. Methods: Following PRISMA 2020 guidelines, we conducted a comprehensive literature search across multiple databases (SciSpace, Google Scholar, PubMed) from January 2016 to March 2026. Studies were included if they reported empirical evidence on AI interventions targeting student engagement or classroom interaction outcomes in educational settings. Two independent reviewers screened 267 unique records, assessed 204 full-text articles, and included 142 studies in the final synthesis. Risk of bias was assessed using the ROBINS-I tool for six representative studies. Results: From 267 unique records identified, 142 studies met inclusion criteria after title/abstract screening and full-text assessment. Six representative studies (N=50–20,000+ participants) demonstrated that AI interventions—including personalized recommendation systems, intelligent tutoring systems, conversational agents, and adaptive learning platforms—consistently improved student engagement metrics. Two randomized controlled trials showed low risk of bias, while four quasi-experimental studies showed moderate risk. AI-driven interfaces increased engagement by up to 25.13% in large-scale field tests. Personalized AI recommendations significantly improved learning performance and engagement, particularly for students with moderate motivation levels. AI tutors enabled students to learn more than twice as much in less time compared to traditional active learning approaches. Conclusions: The evidence demonstrates that AI technologies can effectively enhance student engagement and classroom interaction across diverse educational contexts. Randomized controlled trials provide the strongest evidence, while quasi-experimental studies show consistent positive effects despite moderate methodological limitations. Future research should prioritize rigorous experimental designs with preregistration, comprehensive reporting of missing data, and investigation of long-term effects and equity considerations.

Abstract: In modern days, getting his first job is a very hard process for newly graduated students. Several factors contribute to this issue: no experience, poor resume qualities, few knowledge of job market and required skills for a given job title, no real exposure to job interview (phone, virtual, physical). In the past 30 to 50 years, structured human resources agencies played great role helping young graduates to be well prepared for job readiness. Techniques as how to write a good resume, determining job title and job profile in a particular domain, how to handle a phone, virtual and physical interview were taught to a candidate. Traditional advisory systems are often insufficient in addressing these structural issues at scale. This paper presents an AI-powered web-based career development platform designed to enhance employability among students and job seekers in Côte d'Ivoire. The built application is called DIJOB (Digitalized Job), DIJOB integrates Groq’s LLaMA 3.3-70B large language model to provide four core services: intelligent job search with AI-based CV matching, automated résumé quality assessment, skill compatibility scoring against job descriptions, and a personalized eleven-module career coaching system. The coaching module includes salary estimation in FCFA, LinkedIn profile optimization, and interview preparation guidance. The system is implemented using Jakarta EE 10, GlassFish 7, MySQL 8, and a responsive XHTML frontend, following a three-tier architecture with a RESTful API layer. Results indicate that the platform provides real-time, actionable career insights, including résumé scoring, skill gap analysis, and personalized career recommendations. DIJOB shows strong potential in improving alignment between job seekers and employer expectations, thereby contributing to reduced skills mismatch and improved employability outcomes.

Abstract: Inflation is one of the most significant macroeconomic indicators influencing the stability and sustainable growth of an economy. During periods of economic uncertainty, particularly the COVID-19 pandemic, inflation exhibited substantial fluctuations characterized by extreme observations and increased volatility, indicating the presence of fat-tailed behaviour. Such characteristics often reduce the effectiveness of conventional statistical measures, making robust estimation techniques essential for reliable analysis. This study investigates the behaviour of inflation in India and examines its relationship with the Reserve Bank of India's (RBI) monetary policy, represented by the repo rate, over the period from 2014 to 2022. Monthly data obtained from the Reserve Bank of India (RBI) Database on Indian Economy (DBIE) are used for the empirical analysis. To obtain a robust measure of central tendency in the presence of extreme observations, a 25% trimmed mean is employed and compared with the conventional arithmetic mean. Furthermore, a simple linear regression model is developed to examine the relationship between inflation and the repo rate, and the model parameters are estimated using the Maximum Likelihood Estimation (MLE) method. The empirical findings indicate that inflation exhibited noticeable fat-tailed characteristics during the pandemic period, while the trimmed mean provided a more stable and representative estimate than the conventional mean. The regression analysis further demonstrates a significant association between inflation and the repo rate, highlighting the effectiveness of monetary policy interventions in maintaining price stability during periods of economic uncertainty. The study concludes that robust statistical techniques, such as trimmed mean estimation combined with maximum likelihood methods, provide valuable tools for analysing inflation dynamics and supporting evidence-based monetary policy decisions.

Abstract: The rapid advancement of digital technologies has significantly transformed the education sector by introducing intelligent learning environments, online learning platforms, Learning Management Systems (LMS), Massive Open Online Courses (MOOCs), and virtual classrooms. These technological developments generate enormous volumes of educational data that capture students' learning activities, academic performance, attendance, assignment submissions, examination scores, participation in online discussions, and interaction with digital learning resources. The availability of such educational data has created new opportunities for educational institutions to improve teaching strategies, personalize learning experiences, and enhance academic outcomes through data-driven decision-making. Learning Analytics has emerged as a multidisciplinary research field that combines Artificial Intelligence (AI), Educational Data Mining (EDM), Machine Learning (ML), Data Analytics, and statistical techniques to analyze educational data and predict student performance with greater accuracy. By identifying learning patterns and behavioral characteristics, learning analytics enables educators to provide timely interventions that support student success and reduce academic failure. Student performance prediction has become one of the most important applications of learning analytics because academic achievement directly influences educational quality, institutional effectiveness, and workforce development. Traditional evaluation methods primarily depend on periodic examinations and manual assessment, which often identify learning difficulties only after students experience poor academic performance. Such delayed identification limits the opportunity for educators to provide timely academic support. In contrast, learning analytics continuously monitors students' learning behavior throughout the educational process, enabling early detection of students who may be at risk of poor performance, course failure, or dropout. This proactive approach allows instructors to implement personalized learning strategies and academic interventions before significant learning problems occur. This research investigates the application of learning analytics for predicting student academic performance using multiple educational indicators collected from both traditional and digital learning environments. The proposed study considers a comprehensive set of predictive variables, including attendance records, assignment completion rates, quiz performance, laboratory activities, examination marks, participation in online learning platforms, classroom engagement, discussion forum activities, learning duration, assessment consistency, and demographic information.

Abstract: Research on composite materials has gradually replaced traditional materials and alloys in an effort to create effective and cost-effective solutions for a range of applications. Metal Matrix Composites (MMCs) offer several benefits over traditional composites, including a lower thermal expansion coefficient, improved resistance to wear and abrasion, a higher strength-to-weight ratio, and reduced density. This review focuses on MMCs based on aluminium, magnesium, copper, titanium, and zinc as well as their alloys. It examines their physical and mechanical properties, manufacturing techniques (such as in-situ, liquid-phase, and solid-phase manufacture), and recent advancements. The properties of MMCs have been enhanced. As a result, they are suitable for critical applications in electronics, autos, and aerospace. Significant findings show how they can overcome the shortcomings of conventional materials by improving a range of mechanical properties. Their tensile characteristics, density, thermal expansion coefficient, elasticity modulus, hardness and fracture resistance, fatigue resistance, creep stiffness, and electrical conductivity can all be enhanced by using reinforcing techniques. The text also emphasises how important it is to select the right production processes to obtain the necessary characteristics while lowering costs and defects. This evaluation is a comprehensive resource for researchers and business professionals. It highlights current advancements, challenges, and the vast potential of MMCs as future resources.

Abstract: Coconut is an economically important plantation crop whose productivity is significantly affected by leaf diseases such as Leaf Rot, Grey Leaf Spot, and Bud Rot. Early detection of these diseases is essential to reduce crop losses and improve yield. Conventional disease diagnosis through manual inspection is time-consuming, subjective, and unsuitable for large-scale plantations. This paper proposes an Attention-Based Deep Learning Framework for the early detection and classification of coconut leaf diseases. The proposed framework integrates image preprocessing, data augmentation, transfer learning, and a Convolutional Block Attention Module (CBAM) to enhance feature extraction. The attention mechanism enables the model to focus on disease-affected regions while suppressing irrelevant background information. A convolutional neural network is used to classify healthy and diseased leaf images with improved accuracy. The model is evaluated using standard performance metrics, including accuracy, precision, recall, F1-score, and confusion matrix. Experimental results demonstrate that the attention-based framework outperforms conventional CNN models in detecting early-stage disease symptoms. The proposed approach is computationally efficient and suitable for real-time deployment on mobile and edge devices. It provides an effective decision-support tool for farmers and agricultural experts, contributing to improved disease management and sustainable coconut cultivation.

Abstract: The increasing demand for sustainable energy resources, along with growing environmental concerns related to fossil fuel consumption, has accelerated research into alternative fuels for internal combustion engines. This study focuses on the experimental investigation and performance analysis of an internal combustion engine operated with alternative fuel as a potential replacement for conventional diesel fuel. The experimental investigation was conducted to evaluate the effects of alternative fuel usage on engine performance and exhaust emission characteristics under different operating conditions. The performance evaluation was carried out based on key parameters, including brake power, torque, brake thermal efficiency (BTE), and brake-specific fuel consumption (BSFC). In addition, the emission characteristics were analyzed by measuring exhaust gases such as carbon monoxide (CO), unburned hydrocarbons (HC), oxides of nitrogen (NOx), carbon dioxide (CO₂), and smoke opacity. The results demonstrated that alternative fuel operation produced comparable engine performance with conventional diesel fuel. Variations in brake power, torque, thermal efficiency, and fuel consumption were observed due to differences in fuel properties, combustion behavior, and energy content. The alternative fuel showed a slight increase in fuel consumption due to its lower calorific value; however, it provided improved emission characteristics by reducing CO, HC, and smoke opacity emissions. A minor change in NOx emissions was observed, which was mainly associated with variations in combustion temperature and oxygen availability during the combustion process. Overall, the experimental findings indicate that alternative fuels can be effectively utilized in internal combustion engines while maintaining satisfactory performance and reducing harmful exhaust emissions. The study highlights the potential of alternative fuels as sustainable energy solutions for cleaner and more efficient engine operation.
