Abstract: With an increasingly large number of online services and secure access applications, trusted identity authentication has become an important issue. Although biometric authentication has higher security assurance than traditional security methods, single biometric mode authentication systems have performance issues in terms of degradation due to environmental factors, occlusions, lighting, and spoofing attacks. In this respect, this study proposes an original multimodal biometric authentication approach that combines ear contour biometric recognition with palmprint biometric recognition using the Enhanced and Discriminative Competitive Code (EDCC) method. The proposed multimodal biometric authentication method has the synergistic ability of two biometric modes. The ear contour-based biometric recognition technique extracts the helix and conchal curvatures of the human ear, providing geometric information that is less affected by illumination conditions. Simultaneously, the EDCC-based palmprint recognition technique extracts the prevalent orientation patterns of the lines and ridges on the human palm, providing robustness to noise and minute geometric distortions. These two biometric modalities provide complementary information about the user’s biometric traits and can thus be fused through feature-level fusion to provide a single and robust biometric representation.The performance of the proposed multimodal biometric authentication technique is evaluated on two challenging and widely available biometric datasets, namely the PolyU-IITD contactless palmprint database and the EarVN1.0 unconstrained ear image database. The performance evaluation of the proposed multimodal biometric authentication technique clearly reveals its superior performance compared to other state-of-the-art biometric authentication approaches, including unimodal and hybrid biometric authentication schemes, as it provides a recognition accuracy of 99.01% and an extremely low EER of 0.11% for the PolyU-IITD contactless palmprint database and EarVN1.0 unconstrained ear image database, respectively.

Abstract: Drosophila melanogaster serves as an indispensable in vivo model system for mapping how external environmental variations and nutritional inputs dictate physiological adaptations and behavioural choices. This study presents a multi-generational evaluation of how dietary variance (standard cornmeal vs. banana-enriched vs. orange-enriched media) pairs with photoperiodic conditions to modulate ontogeny, locomotor agility, and larval chemotaxis. Across three successive generations (F1–F3), cohorts reared on a nutrient-dense banana medium exhibited accelerated metamorphic transitions and robust pupation rates. Conversely, an orange-supplemented diet delayed developmental milestones and reduced total yield compared to uniform controls. Photoperiodic restrictions (sustained dark phases) consistently decelerated growth metrics and decreased motor output across all dietary groups. Quantifiable behavioural deficits under low-light regimes were verified via negative geotaxis assays, where light-exposed flies displayed markedly superior vertical climbing performance. Furthermore, larval olfactory assays revealed a stark chemotactic bias toward volatile food-derived attractants (ethyl acetate) over aversive ionic stimuli (sodium chloride). Taken together, these data illuminate the complex interplay between systemic metabolic programming and sensory-driven behavioural phenotypes in response to immediate ecosystem shifts.

Abstract: Motor impairments such as ALS, locked-in syndrome, and cerebral palsy severely limit an individual's ability to interact with digital systems using conventional input devices. This paper presents GazeSpeak, an AI-powered Eye Gaze Communication System that enables motor-impaired users to communicate through voluntary eye movements alone. The system extracts real-time gaze coordinates using OpenCV and MediaPipe, maps them onto interactive screen elements via a TensorFlow regression model, and integrates a transformer based NLP module for context-aware word prediction. A dwell-based selection mechanism activates interface targets without any physical input. Experimental evaluation across twenty participants demonstrates a gaze detection accuracy of 94.2%, end-to-end latency of 38ms, top-3 word prediction accuracy of 87.6%, and communication throughput of 10.6 WPM, with a System Usability Scale score of 84.4 confirming excellent user acceptance. The results establish GazeSpeak as an effective, open-source, and cost-accessible assistive communication platform for real-world deployment.

Abstract: In the digital banking era, effective marketing lead generation depends on leveraging hetero-geneous, multimodal customer data. Traditional predictive models primarily rely on tabular attributes, overlooking the relational and contextual information inherent in customer networks. This paper proposes a Graph Neural Network (GNN)-based framework that integrates multi-modal data—including structured CRM attributes, transactional records, and unstructured call transcript text—to predict customer lead conversion in banking. The proposed system models customers as nodes in a heterogeneous graph with relationships based on transactional similarity and communication patterns. Using a multimodal embedding strategy, the model learns customer representations via Graph Convolutional and Attention layers. Empirical results on the UCI Bank Marketing dataset demonstrate an ROC-AUC of 0.87 and accuracy of 0.886, with significant improvements over logistic regression and XGBoost baselines. Extended experiments using a heterogeneous multi-source graph (MovieLens, Last.FM, Amazon co-purchase, OGB-MAG) further confirm the framework’s superiority: accuracy 0.893 and F1-score 0.596 versus a logistic regression baseline that degenerates to F1= 0.000, AUC= 0.500. The paper details system design, dataset structure, implementation, graph construction methodology, and performance evaluation.

Abstract: In the modern digital banking era, effective marketing lead generation depends on leveraging heterogeneous, multimodal customer data. Traditional predictive models primarily rely on static, flat tabular attributes, overlooking the relational and temporal information inherent in customer transaction histories and support networks. This paper proposes MTHGT, a Multimodal Temporal Heterogeneous Graph Transformer framework that integrates multimodal data—including structured CRM attributes, sequential transactional records, and unstructured call transcripts—to predict customer lead conversion in banking. The proposed system models customers, transactions, locations, and events as nodes in a heterogeneous graph with relationships based on transactional similarity, campaign logs, and temporal history. Using a multimodal embedding strategy, the model learns customer representations via Graph Transformer layers with type-aware, distance, and temporal bias encodings. Empirical results on the Multimodal Banking Dataset (MBD; 85,620 client-month nodes, 2.26% positive rate) demonstrate that graph-based models outperform tabular baselines on ranking (HGT ROC-AUC of 0.7809 ± 0.0092 and MTHGT ROC-AUC of 0.7763 ± 0.0160 vs. Logistic Regression ROC-AUC of 0.7397 ± 0.0002). Furthermore, MTHGT improves F1-score over HGT (0.0778 ± 0.0225 vs. 0.0651 ± 0.0050) and exposes dynamic modality attributions (CRM features: 25%, dialogue text: 36%, temporal transactions: 39%), enabling explainable CRM lead scoring. The paper details system design, dataset structure, implementation, graph construction methodology, performance evaluation, and outlines a roadmap to bridge the tabular baseline gap using Focal Loss and behavioral k-NN edges.

Abstract: Cloud-based applications increasingly rely on multiple database systems to handle diverse data models and workloads, yet managing these heterogeneous environments remains complex and resource-intensive. Traditional Database-as-a-Service platforms often introduce vendor lock-in, limited flexibility, and high costs, restricting their suitability for academic and research use. To address these challenges, this research proposes an open-source, AI-powered Cloud Database-as-a-Service platform that unifies the management of SQL, NoSQL, and in-memory databases using Kubernetes-based container orchestration. The system integrates AI-driven natural language assistance for schema generation and query formulation, along with real-time monitoring using Prometheus and Grafana. By combining automation, intelligent interaction, and cost-effective deployment, the platform aims to improve accessibility, efficiency, and scalability in cloud-native database management.

Abstract: This research paper investigates the effect of data-driven personalization on customer engagement and brand loyalty within the digital marketing ecosystem. As organisations accumulate unprecedented volumes of consumer data through digital touchpoints—spanning e-commerce platforms, mobile applications, social media, and connected devices—the capacity to deliver highly individualised marketing experiences has grown substantially. Yet the relationship between personalization, engagement, and loyalty is complex, non-linear, and moderated by a range of consumer, contextual, and technological variables that existing literature has not yet fully integrated into a unified framework. Drawing on the Elaboration Likelihood Model (ELM), Self-Determination Theory (SDT), Relationship Marketing Theory, and the Stimulus-Organism-Response (S-O-R) framework, this paper develops a comprehensive conceptual model that traces the pathway from data-driven personalization through customer engagement to brand loyalty, incorporating personalization relevance, perceived autonomy, privacy concern, and algorithmic transparency as key moderating and mediating constructs. The paper reviews the theoretical foundations of these relationships, analyses six real-world case studies from diverse sectors including streaming, e-commerce, food delivery, and retail, and proposes a research agenda for advancing understanding of personalization dynamics in contemporary digital marketing. Key findings indicate that data-driven personalization significantly enhances customer engagement when it is perceived as relevant and non-intrusive, and that sustained engagement is the primary pathway through which personalization generates brand loyalty. However, the study also identifies critical conditions under which personalization can undermine trust and loyalty—specifically when personalisation becomes too precise, violates contextual norms, or operates without transparency. The paper concludes with strategic implications for marketers, recommendations for ethical personalization design, and directions for future empirical research.

Abstract: Chenopodium album (Linn.), commonly known as lamb's quarters or bathua, is a fast-growing annual plant of the family Amaranthaceae with a long history of traditional medicinal use. This study investigates the antimicrobial potential of methanol and acetone leaf extracts of C. album against six pathogenic bacteria and six fungal strains using disc diffusion, well diffusion, and poisoned food techniques. Extraction was performed using the Soxhlet method with 25 g of powdered dried leaf material in 50 ml of methanol and acetone solvent mixture. Results demonstrated notable antibacterial activity against both Gram-positive and Gram-negative organisms, with acetone extract producing the largest inhibition zones against Escherichia coli (19.5 mm) by disc diffusion and 20.1 mm by well diffusion. Antifungal assays revealed that a mixture of methanolic and acetone extracts achieved up to 99% mycelial inhibition against Aspergillus niger at 7 days incubation. These findings suggest that C. album harbors broad-spectrum antimicrobial compounds with significant pharmaceutical potential.

Abstract: Concrete is one of the most widely used construction materials, and its compressive strength is a key parameter that determines its structural performance and durability. Traditionally, determining the compressive strength of concrete requires laboratory testing, which is time-consuming, costly, and dependent on curing conditions and sample preparation. In this study, a data-driven approach is applied to predict the compressive strength of concrete using regression analysis in Microsoft Excel. A dataset containing input variables such as cement content, water-cement ratio, fine and coarse aggregate proportions, and curing age is analysed. Various regression techniques—such as linear, multiple linear, and polynomial regression—are implemented to develop predictive models. The correlation between experimental and predicted results is evaluated using statistical indicators like R², standard error, and residual analysis. The study demonstrates that regression models can effectively predict concrete compressive strength with reasonab le accuracy, thereby reducing the need for extensive experimental trials. This approach highlights the potential of Excel as a simple yet powerful tool for engineers and researchers to perform predictive modelling and optimise concrete mix design. The compressive strength of concrete is a crucial property that determines its quality and load-bearing capacity. Conventionally, this strength is obtained through laboratory testing after curing, which can be time-consuming and resource-intensive. This project focuses on predicting the compressive strength of concrete using regression analysis in Microsoft Excel. By utilising input parameters such as cement content, water-cement ratio, fine and coarse aggregates, and curing age, a regression model is developed to estimate strength values. Multiple linear regression is applied to establish a relationship between these variables and the compressive strength. The accuracy of the model is evaluated through statistical measures like the coefficient of determination (R²) and error analysis. The results indicate that regression-based prediction provides a reliable and cost-effective alternative to traditional testing methods. This approach demonstrates the usefulness of Excel as an accessible tool for data analysis and decision-making in civil engineering applications.

Abstract: The adoption of Industry 4.0 technologies has increased the need for seamless integration between Manufacturing Execution Systems (MES) and Enterprise Resource Planning (ERP) platforms. SAP Digital Manufacturing (SAP DM), built on the SAP Business Technology Platform (BTP), provides a cloud-based solution for managing and optimizing manufacturing operations. While integration with SAP S/4HANA is supported through standardized mechanisms such as IDocs, APIs, and SAP Cloud Integration, integrating SAP DM with non-SAP ERP systems, including Oracle ERP Cloud, Microsoft Dynamics 365, and Infor CloudSuite, presents additional challenges related to data exchange, interoperability, and process synchronization. This paper proposes a unified four-layer integration framework for connecting SAP Digital Manufacturing with both SAP and non-SAP ERP systems. The framework focuses on master data synchronization, production order management, middleware architecture, security governance, and implementation strategy. By analyzing industry practices and documented integration approaches, the study demonstrates how organizations can establish a scalable and standardized manufacturing integration landscape. The paper also discusses future opportunities in event-driven architectures, artificial intelligence-based production planning, and digital twin technologies.
