Abstract: This bibliographic analytical paper systematically evaluates the theoretical and empirical literature surrounding the integration of Information and Communication Technology (ICT) in secondary school systems, with specific reference to the Indian classroom context. Positioned within the scholarly mandates of the National Education Policy (NEP) 2020 and institutional research criteria at Sabarmati University, this analysis explores the structural mechanisms through which technological treatments influence cognitive academic outcomes and learner dispositions. Historically, educational technology research has been limited by a reliance on un-moderated, direct-effect correlational models, leaving an empirical gap regarding the unique, conditional variables that determine localized instructional success. This paper traces the evolution of educational technology literature from early psychological frameworks to contemporary digital-age learning models, culminating in a thematic assessment of the "no significant difference phenomenon." By synthesizing global meta-analyses alongside domestic quasi-experimental trials, this paper maps the research gaps that justify an experimental investigation into the moderating role of student attitudes within an Aptitude-Treatment Interaction (ATI) framework. The analysis concludes that sustainable technology implementation requires moving past simple device provisioning to prioritize the psychological readiness and attitudinal architecture of the individual learner.

Abstract: Denial of Service (DoS) attacks are one of the most common cyber threats that disrupt network services by overwhelming systems with malicious traffic. Traditional cloud-based detection methods often experience higher latency and increased bandwidth usage, making them less effective for real-time protection. The DoS Attack Detection System Using Edge Machine Learning introduces an intelligent approach that detects malicious network traffic directly at edge devices before it reaches the central server. By leveraging Edge Computing, Machine Learning, and real-time traffic analysis, the system identifies abnormal network behavior with low latency and improved accuracy. This approach reduces server overload, enhances network security, and ensures continuous availability of services while providing a scalable and efficient solution for modern IoT and edge-enabled environments.

Abstract: Synthetic Aperture Radar is vital remote sensing technology, offering all-weather, day-and- night imaging ca-pabilities. However, its inherent grayscale nature, along with speckle noise, presents significant challenges for interpretation by non-specialists. This review addresses recent advancements in applying deep learning to SAR colorization, a technique aimed at enhancing visual interpretability of these images while preserving unique radiometric properties. The primary motivation is to bridge the gap between complex radar data, intuitive visual analysis, thereby broadening its application in fields like disaster management, environmental monitoring. Major themes covered include critical distinction between grayscale colorization, SAR-tooptical translation, evolution of methodologies from tradi-tional regression to advanced deep learning models, lack of standardized evaluation protocols that has hindered progress. Existing technologies often involve convolutional neural networks, Generative Adversarial Networks (GANs). This review high-lights a proposed methodology centered on conditional GAN within a complete benchmarking protocol utilizing synthetically generated ground truth via intensity-high saturation (IHS) fusion. Key features of this approach include an end-to-end supervised learning framework, use of domain-specific evaluation metrics (Q4, NRMSE, SAM). This advancement holds significant impli-cations for real-time disaster response, contributes to Sustainable Development Goals (SDGs) such as ”Sustainable Cities and Com-munities”, ”Climate Action” by making critical environmental data more accessible, actionable.

Abstract: Short-term electric price prediction is important in deregulated power markets and operations as well as planning processes as it aids in the bidding process, risk management and demand response programs. The growing infiltration of renewable energy sources, as well as switching variability of the loads, and market uncertainties, has brought about high nonlinearity and volatility in the electricity price dynamics, which restrain the applicability of traditional forecasting techniques. In solving such challenges, this paper suggests a hybrid deep learning forecasting structure combined with efficient feature selection mechanism to predict short-term price of electricity. The advanced feature selection methods are used in the proposed approach to determine the most informative market, demand, and generation-related variables and to lower the dimensions, as well as to remove redundant information. A hybrid deep learning model, which is a combination of the positive attributes of sequential and nonlinear learning structures, is subsequently trained exploiting the chosen features to absorb intricate temporal variations and price surges. An evaluation of the model by real-world data of the electricity market and a comparison with the traditional statistical methods and individual machine learning are conducted. The simulation outcomes prove that the suggested hybrid structure is more accurate in predictions, more robust, and converges faster, which is indicated by the lower error indicators like MAE, RMSE, and MAPE. In addition, the feature selection step will increase the interpretability and the computational efficiency of models without affecting prediction accuracy. The results attest to the fact that the suggested approach is highly applicable when it comes to short-term electricity price prediction in highly volatile and renewable-based power markets.

Abstract: Background: Chronic cigarette smoking induces systemic pathophysiological changes, leading to respiratory muscle deconditioning, impaired pulmonary ventilation, and peripheral muscle fatigue. While Inspiratory Muscle Training (IMT) targets central ventilatory drive, progressive resistance training addresses systemic deconditioning. Aim: To evaluate the combined effectiveness of Inspiratory Muscle Training and DeLorme progressive resistance exercise on respiratory muscle strength, pulmonary function, and functional capacity in active smokers. Methods: This pre-post experimental study enrolled 30 active young adult smokers (aged 20–40 years; mean smoking history: 5.4 ± 1.8 pack-years). Participants underwent a structured 6-week intervention consisting of targeted IMT using a threshold resistance device (40–60% of Maximal Inspiratory Pressure [MIP], 20 min/day, 5 days/week) and DeLorme progressive resistance exercise focused on the bilateral quadriceps femoris muscle groups (3 sets of 10 repetitions at 50%, 75%, and 100% of 10-Repetition Maximum [10RM], 5 days/week). Outcome measures included MIP, spirometric parameters (FEV1, FVC, MVV), functional capacity via the Six-Minute Walk Test (6MWT), and exertional dyspnea via the Borg CR10 Scale. Pre- and post-intervention data were analyzed using a paired t-test. Results: Following the 6-week training protocol, participants demonstrated statistically significant improvements across all primary and secondary parameters (p < 0.001). MIP increased from 68.4 ± 7.2 cmH2O to 84.6 ± 6.8 cmH2O, and 6MWT distance improved by a mean of 74.2 meters. Exertional dyspnea on the Borg scale decreased significantly from 5.8 ± 1.1 to 3.2 ± 0.9. Conclusion: Integrating IMT with DeLorme progressive peripheral resistance exercise significantly enhances respiratory muscle strength, functional exercise tolerance, and ventilatory efficiency in active smokers. This dual-component approach addresses both central respiratory limitations and peripheral skeletal muscle deconditioning.

Abstract: The transition from junior to senior school under Kenya's Competency-Based Education (CBE) requires learners to select academic pathways that align with their competencies and interests. This transition presents a challenge because pathway selection requires personalized guidance while ensuring the privacy of sensitive student information. Existing educational recommender systems predominantly rely on centralized data processing, exposing learner data to privacy risks and limiting the secure exchange of information across institutions. This study proposes a privacy-preserving personalized pathway recommender system that integrates federated learning, cosine similarity, and Random Forest to support academic pathway recommendation without sharing raw student data. Cosine similarity was employed to model learner competency profiles and measure their alignment with predefined pathway requirements. The resulting similarity scores were incorporated into a Random Forest classifier through feature engineering to improve pathway prediction accuracy. A horizontal federated learning framework enabled multiple schools to collaboratively train the recommendation model by exchanging only model updates while retaining student records locally. The proposed model was evaluated using accuracy, precision, recall, and F1-score. Experimental results showed that integrating cosine similarity with Random Forest improved pathway classification performance, while the federated recommender system achieved an accuracy of 86.54%, outperforming the centralized recommender approach while preserving student privacy. The proposed framework provides an effective and privacy-preserving decision-support tool for personalized academic pathway recommendation within Kenya's Competency-Based Education. The study demonstrates that integrating federated learning with content-based filtering and machine learning can simultaneously enhance recommendation accuracy, personalization, and data privacy in educational environments.

Abstract: The increasing demand for lightweight, safe, and fuel-efficient vehicles has driven structural optimisation of automotive body frames. A passenger vehicle body shell was designed in SolidWorks and analysed in ANSYS Workbench 2024 R1 under frontal and rear impact at 60, 80, and 100 km/h using five material configurations: ABS, structural steel, Carbon Fiber Reinforced Polymer (CFRP), Glass Fiber Reinforced Polymer (GFRP), and a hybrid CFRP+GFRP laminate. Performance metrics — total deformation, equivalent stress, equivalent strain, and factor of safety (FOS) were extracted for each scenario. Modal analysis extracted the first six natural frequencies and mode shapes. Results show CFRP achieves superior crashworthiness (FOS > 2.40 at all speeds) and highest natural frequencies (86.38–153.62 Hz), while the hybrid composite nearly replicates CFRP performance at reduced cost. ABS is structurally unsuitable and steel approaches failure at 100 km/h. The hybrid CFRP+GFRP laminate is the optimal lightweight alternative to conventional steel for passenger car body shell applications.

Abstract: Artificial Intelligence (AI) systems have become essential across industries, supporting decision-making, automation, healthcare, finance, and cybersecurity. However, the increasing complexity of AI pipelines introduces significant risks related to data integrity, model drift, security vulnerabilities, regulatory compliance, and operational failures. Embedding governance within AI pipelines provides a structured framework to ensure accountability, transparency, recoverability, and resilience. This paper examines governance mechanisms integrated throughout the AI lifecycle and demonstrates how embedding governance enhances system recovery while minimizing operational, ethical, and security risks. The study proposes a governance-driven AI pipeline architecture incorporating continuous monitoring, version control, audit trails, explainability, and automated rollback mechanisms. The findings indicate that governance significantly improves reliability, trustworthiness, and regulatory compliance while reducing downtime and model-related failures.

Abstract: Calcium deficiency is a major but underrecognized nutritional concern among Indian women, particularly during the premenopausal transition. Emerging evidence indicates that bone mineral loss and biochemical deficiencies begin before menopause. This review synthesizes recent literature (2020–2025) on calcium intake, associated symptoms, and risk factors among Indian women aged 35–50 years. Available data suggest that a large proportion of women consume inadequate calcium, often compounded by widespread vitamin D deficiency. Clinical manifestations during premenopause are frequently subtle, including musculoskeletal discomfort, fatigue, and mood disturbances, contributing to underdiagnosis. Early screening and preventive interventions are critical to reduce long-term skeletal morbidity.

Abstract: This Paper analyzed the effects of the cosmological constantΛ in the context of the Bianchi Type I cosmological model. The Bianchi Type I model represents an anisotropic but spatially flat universe, where expansion rates can differ along three spatial directions.This study analyzes the effects of the spatial directions with respect to axes . The cosmological, plays a significant role in the universe expansion. This work aims to understand how influences the expansion, energy density, and anisotropy of the universe. Einstein's field equations with variable cosmological constant if considered in the presence of a perfect fluid for a Bianchi type I universe by assuming that the cosmological term is proportional to the square of the Hubble parameter. The variation law for vacuum density was recently proposed by many researches on the basis of the quantum field estimation in a curved expanding background. The cosmological term tends asymptotically to a genuine cosmological constant and the model tends to a de-Sitter universe. More obtained some new results by using a slightly different method from that of other researchers obtained the result that the present universe is accelerating with a large fraction of cosmological density in the form of a cosmological term.
