Ant Colony Optimization with Capacity-Aware Pheromone Models for Load-Balanced Service Placement in Fog Infrastructures
type: item
description: Fog computing extends cloud capabilities toward the network edge to support latency-sensitive and bandwidth-intensive services arising from the proliferation of Internet of Things devices. In such infrastructures, services must be placed on heterogeneous fog nodes with limited capacity, while traffic demands vary over time and space. Unbalanced placement can lead to resource hot-spots, increased response times, and degraded quality of service. Traditional deterministic optimization methods often become intractable at the scale and dynamism of realistic fog deployments, motivating heuristic and metaheuristic approaches. This paper investigates ant colony optimization strategies for load-balanced service placement in fog infrastructures, focusing on capacity-aware pheromone models. The study considers a generic fog topology with constrained compute and bandwidth resources, a set of multi-tenant services with heterogeneous demands, and a traffic matrix describing the association between end-user regions and services. The placement problem is formulated as a linear mixed-integer model that jointly captures capacity constraints, routing decisions, and load-balance objectives. Upon this model, a family of ant colony algorithms is constructed in which pheromone values explicitly encode residual capacities, congestion indicators, and marginal load-balancing costs. Evaporation and reinforcement rules are designed to avoid convergence to placements that violate capacity limits or create persistent hot-spots. The resulting algorithms are discussed in terms of convergence behavior, structural properties of produced placements, and computational complexity. Numerical experiments on synthetic fog topologies illustrate how capacity-aware pheromone designs influence load distribution, path selection, and robustness under changing workload conditions.

Evaluation of Probabilistic Conflict Detection and Resolution for BVLOS UAS Under Surveillance and Communication Constraints
type: item
description: Beyond visual line-of-sight unmanned aircraft systems are being deployed in low-altitude airspace for inspection, logistics, and monitoring, where heterogeneity of platforms and infrastructures intensifies the need for systematic conflict management. Existing separation assurance concepts often assume reliable cooperative surveillance and continuous communication, conditions that are not guaranteed in fragmented coverage, mixed equipage, or contested environments. Under such conditions, deterministic conflict detection and rule-based resolution may be either too conservative or operationally fragile, motivating explicit treatment of probabilistic uncertainty, delayed state information, and intermittent command and control links. This paper examines probabilistic conflict detection and resolution strategies for multiple vehicles operating beyond visual line-of-sight subject to surveillance errors, correlated track losses, communication latency, packet loss, and asynchronous decision making. A unified modeling framework is constructed in which navigation, sensing, and communication artifacts contribute to stochastic relative state estimates used to trigger conflict alerts and synthesize resolution maneuvers. Several algorithmic variants are evaluated, including prediction-based alerting with bounded risk, decentralized chance-constrained trajectory adjustment, and policies that adapt to context-dependent loss-of-link probabilities. The study quantifies how surveillance quality, communication availability, and algorithm design interact to influence conflict probability, alert volume, trajectory deviation, and residual mid-air collision risk across representative operational scenarios. The analysis aims to describe performance and trade-offs without assuming idealized infrastructures, providing a basis for parameterizing risk-based separation requirements and for assessing the feasibility of scalable beyond visual line-of-sight operations under realistic technical const…

Examining the Long-Term Economic Returns from Investments in Mental Health Interventions Within Corporate and Public Sectors
type: item
description: Mental disorders have persistent effects on productivity, earnings, and social participation, and they impose costs that accumulate across life cycles and generations. Organizations and governments increasingly fund interventions that range from brief psychosocial programs to digitally enabled care pathways deployed at scale. This study synthesizes economic mechanisms and long-horizon valuation methods to examine the long-term returns from investments in mental health interventions spanning corporate and public sectors. The analysis integrates firm-level productivity, labor market dynamics, healthcare utilization, education and justice externalities, and intergenerational transmission channels into a unified perspective on durable value creation. A cross-sector lens clarifies how corporate investments primarily monetize private benefits through absenteeism and presenteeism reductions, retention gains, and occupational safety, while public investments realize broader fiscal and societal payoffs through tax bases, transfer offsets, and avoided downstream costs. To evaluate persistence, we embed transition dynamics of mental health states, depreciation of intervention effects, and capital deepening responses that jointly shape macroeconomic spillovers. We discuss estimation strategies, measurement risks, and heterogeneity by age, job task, and disorder severity, emphasizing generalizability and incentive compatibility. The results provide decision rules for portfolio design under uncertainty, guidance on contracting structures that align private and social returns, and sensitivity to discounting and equity goals. Strategic implications include the use of outcome-linked finance, demand-side reinforcement through procurement, and governance that internalizes spillovers. The paper offers implementable valuation heuristics and modelling templates that enable firms and governments to compare, prioritize, and sequence investments in mental health with transparent, long-run e…

Evaluation of Instrumental Variable Estimators in the Presence of Weak Instruments and Heteroskedastic Errors in Panel Data Models
type: item
description: Instrumental variable (IV) estimation is widely used technique in econometric analysis, especially for tackling problems of endogeneity that can compromise the validity of regression results. When explanatory variables are correlated with the error term, traditional methods such as ordinary least squares (OLS) produce biased and inconsistent parameter estimates. This paper provides a comprehensive evaluation of various instrumental variable estimators when applied to panel data models characterized by weak instruments and heteroskedastic error structures. We examine the finite sample properties of two-stage least squares, limited information maximum likelihood, and generalized method of moments estimators through extensive Monte Carlo simulations. Our analysis reveals that the performance of these estimators deteriorates significantly when instruments are weak, with the degree of deterioration being approximately 15\% to 30\% higher in the presence of heteroskedasticity compared to homoskedastic settings. We develop a robust testing framework for instrument strength that accounts for both cross-sectional and time-series heteroskedasticity patterns commonly observed in panel data. The proposed methodology demonstrates superior finite sample performance, reducing mean squared error by up to 25\% compared to conventional approaches. Additionally, we establish theoretical bounds for the bias and variance of these estimators under weak instrument asymptotics. Our findings suggest that practitioners should exercise considerable caution when employing instrumental variable techniques in panel data contexts, particularly when instrument strength is questionable and error structures exhibit heteroskedastic patterns.

Information Assurance in Distributed Systems: Addressing Integrity and Availability Through Network and System Design
type: item
description: Information assurance in distributed systems has become increasingly critical as organizations migrate their operations to cloud-based and networked environments where data integrity and system availability face unprecedented challenges. This paper examines the fundamental principles and advanced methodologies for ensuring information assurance in distributed computing environments, with particular emphasis on maintaining data integrity and system availability through strategic network and system design approaches. The research investigates how distributed architectures introduce unique vulnerabilities that traditional centralized security models cannot adequately address, including Byzantine fault tolerance, consensus protocol failures, and cascading system degradation. Through comprehensive analysis of fault-tolerant mechanisms, redundancy strategies, and mathematical modeling of system reliability, this study presents a framework for designing resilient distributed systems that can withstand various attack vectors and operational failures. The paper explores advanced techniques including Byzantine agreement protocols, distributed consensus algorithms, and probabilistic reliability models that form the theoretical foundation for robust distributed system design. Practical implementation strategies are examined through the lens of modern distributed architectures, including microservices, containerized environments, and edge computing platforms. The findings demonstrate that effective information assurance in distributed systems requires a multi-layered approach combining cryptographic integrity verification, redundant system architectures, and adaptive fault detection mechanisms. This research contributes to the growing body of knowledge on distributed system security by providing both theoretical foundations and practical implementation guidelines for organizations seeking to enhance their information assurance posture in distributed computing environments.

Evaluation of Safety-Centric Redundancy Architectures in Unmanned Aerial Vehicle Swarm Operations
type: item
description: Unmanned Aerial Vehicle (UAV) swarm technology has rapidly evolved over the past decade, presenting unprecedented capabilities and complex safety challenges for autonomous systems. This paper presents a comprehensive analysis of safety-centric redundancy architectures specifically designed for UAV swarm operations in mission-critical environments. We introduce a novel framework for hierarchical fault tolerance that dynamically adjusts redundancy requirements based on mission parameters, environmental conditions, and emergent behavior patterns. Our approach integrates distributed consensus protocols with Byzantine fault tolerance mechanisms to ensure operational continuity even when facing multiple simultaneous system failures within the swarm. Experimental results demonstrate that the proposed architecture achieves a 99.7\% mission completion rate under simulated cascading failure conditions, compared to 78.4\% for conventional redundancy approaches. Furthermore, the framework reduces computational overhead by 42.3\% through selective activation of redundancy protocols based on real-time risk assessment. These findings suggest that adaptive, context-aware redundancy mechanisms substantially enhance the resilience and operational safety of autonomous UAV swarms in high-stakes applications.

A Policy-Oriented Analysis of Insurance Broker Compensation Structures and Their Influence on Cost Distribution and Access to Healthcare Services
type: item
description: Insurance broker compensation mechanisms represent a critical determinant in healthcare access and cost distribution across diverse populations, yet their systemic impacts remain insufficiently analyzed within contemporary policy frameworks. This research examines the intricate relationship between broker compensation structures, healthcare service accessibility, and cost distribution patterns through comprehensive analysis of commission-based, fee-for-service, and hybrid compensation models. The investigation reveals that traditional commission-based structures create inherent conflicts of interest, leading to premium inflation of approximately 15\% to 23\% while simultaneously reducing coverage options for vulnerable populations. Fee-for-service models demonstrate improved cost transparency but exhibit implementation challenges in rural markets where broker density remains 40\% below urban concentrations. Hybrid compensation frameworks show promise in balancing cost efficiency with equitable access, though regulatory oversight mechanisms require substantial enhancement. The analysis incorporates advanced stochastic modeling to quantify risk distribution patterns and their correlation with compensation incentives. Results indicate that broker compensation structure modifications could potentially reduce healthcare cost disparities by 18\% to 31\% while maintaining service quality standards. Policy implications suggest that regulatory reforms targeting compensation transparency and performance-based incentives could significantly improve healthcare accessibility without compromising market efficiency. These findings contribute to ongoing debates regarding healthcare reform and provide empirical foundation for evidence-based policy development in insurance market regulation.

Artificial Intelligence for Risk Management and Compliance Monitoring in Healthcare Governance Structures
type: item
description: The integration of artificial intelligence (AI) into healthcare governance represents a transformative approach to risk management and compliance monitoring across complex healthcare delivery systems. Traditional healthcare governance frameworks have struggled with increasing regulatory complexity, data volume variability, and operational risk mitigation in rapidly evolving technological landscapes. This research presents a novel computational architecture for dynamic risk stratification and compliance monitoring in healthcare governance structures through the implementation of multi-layered neural networks coupled with reinforcement learning mechanisms. The proposed framework incorporates advanced probabilistic reasoning systems that continuously evaluate governance metrics against established compliance thresholds while simultaneously adapting to emerging regulatory requirements. Experimental validation across 17 healthcare systems demonstrates significant improvements in predictive accuracy of compliance violations (87.3\% sensitivity, 92.1\% specificity) compared to conventional monitoring approaches (64.5\% sensitivity, 71.8\% specificity). Implementation of the proposed system resulted in a 42.6\% reduction in governance-related adverse events and a 31.4\% decrease in regulatory penalties across participating institutions. These findings suggest that AI-augmented governance frameworks can substantially enhance risk management capabilities within healthcare organizations while promoting a more proactive approach to regulatory compliance and institutional oversight.

type: item
description: Rapid advancements in artificial intelligence have catalyzed a transformation in investment advisory services, manifesting through the proliferation of robo-advisors and algorithmic portfolio management platforms. This paper examines the systematic integration of machine learning algorithms, statistical modeling techniques, and real-time data processing architectures to automate asset allocation, risk assessment, and trading strategies. It presents a comprehensive analysis of system architectures, including microservices-based deployment paradigms, scalable cloud infrastructure, and API-driven data ingestion pipelines, underscoring the critical importance of latency optimization, fault tolerance, and data integrity.

Optimizing Healthcare Resource Allocation for Operational Efficiency and Cost Reduction Using Real-Time Analytics
type: item
description: Healthcare systems are constantly struggling to balance managing limited resources to achieve high levels of operational effectiveness and controlling costs. This research proposes a theoretical model for real-time optimization of resource allocation across a network of regional health facilities using real-time analytics. It fills the gap between rigid resource planning and the need for agile, data-driven reactions and provides a systematic approach for regional resource coordination. The model integrates hospital operations' real-time data streams into a dynamic decision space. A mathematical formulation based on optimization is built to assign critical resources – medical staff, hospital beds, and critical equipment – in line with instantaneous demand and projected short-term need. The objective is to minimize overall operating costs while satisfying service demands and reacting to fluctuations in patient volume and acuity. The proposed framework is supported by a real-time analytics architecture that captures and processes real-time data on patient flow, resource usage, and system constraints. An optimization engine uses this data to update allocation decisions in real-time, enabling an adaptive and responsive approach to managing resources. The approach is notionally modest, with emphasis placed on structural integration of analytics and optimisation rather than exaggerated claims of performance. Potential uses are outlined to illustrate how the model can enhance efficiency, reduce waiting times, and restrict wasteful expenditure in theory. As a purely theoretical piece of work, this research highlights the opportunity and the limits of real-time data-driven optimization to control healthcare resources.

Intelligent Control Systems for Renewable Energy Microgrid Management and Sustainable Power Distribution in Urban Environments
type: item
description: This paper presents a comprehensive framework for intelligent control systems designed to optimize the management of renewable energy microgrids in urban environments. We propose a novel hierarchical control architecture that integrates distributed optimization algorithms with adaptive learning mechanisms to address the complex challenges of power distribution in increasingly decentralized energy networks. The framework encompasses demand forecasting, resource allocation, stability analysis, and fault tolerance across heterogeneous renewable energy sources including solar, wind, and energy storage systems. Our approach leverages stochastic optimization techniques to handle the inherent uncertainties in renewable generation while maintaining system robustness. Simulation results demonstrate that the proposed control system achieves 23.7% improvement in energy utilization efficiency and 42.3% reduction in distribution losses compared to conventional methods. Furthermore, the framework accommodates dynamic user preferences and varying grid conditions through a reinforcement learning mechanism that continually refines control parameters. The system architecture supports scalable implementation across diverse urban settings, from individual buildings to neighborhood-scale microgrids, with minimal reconfiguration requirements. This research contributes to the advancement of sustainable energy infrastructure by providing a mathematically rigorous and computationally efficient approach to microgrid management that balances economic considerations with reliability constraints while supporting the integration of an increasing proportion of renewable resources into modern power distribution networks.

Multi-Sensor Data Fusion and Management Strategies for Robust Perception in Autonomous Vehicles
type: item
description: Multi-sensor data fusion has emerged as a critical enabler for robust perception in autonomous vehicles, where the reliability and accuracy of environmental understanding directly impact operational safety and efficiency. This paper presents a comprehensive investigation of cutting-edge data fusion approaches and management strategies that address the challenges of sensor heterogeneity, dynamic driving conditions, and computational constraints. We examine various sensor modalities, including LiDAR, radar, and camera systems, and discuss the advantages of combining their complementary strengths to enhance perception and situational awareness. By exploring state-of-the-art algorithms that integrate machine learning models with probabilistic filtering techniques, we illustrate how high-fidelity maps and real-time sensing can be synchronized to form a unified representation of the environment. Detailed mathematical formulations highlight the role of complex transformations and linear algebraic structures in the data alignment and calibration process. Furthermore, we analyze methods for mitigating sensor uncertainties and propose strategies to handle data overload and synchronization issues under real-time constraints. We present approaches for robust machine learning model design, where domain adaptation and multi-task learning methods enable flexible perception pipelines that generalize to diverse traffic and weather conditions. Ultimately, we identify open research directions and highlight the significance of scalable, secure, and adaptive data management in propelling autonomous vehicle perception forward.

Assessing Monte Carlo Approaches for Silica Gel Network Formation: A Critical Evaluation of Current Methods and Emerging Trends
type: item
description: Silica-based network formation processes underpin numerous technologies, from adsorption systems to catalytic supports, yet the underlying mechanisms of gelation remain challenging to capture in computational models. Stochastic methods have long been considered valuable for exploring these processes due to their flexibility in addressing multi-scale phenomena and intrinsic randomness in reaction pathways. Monte Carlo techniques in particular can incorporate a range of energy barriers, site-specific reactivities, and spatiotemporal fluctuations that drive gelation. Recent studies highlight the effectiveness of evolving Monte Carlo frameworks to examine hydrolysis, condensation, and network restructuring steps, offering new insights into cluster formation dynamics. Additionally, there is growing emphasis on capturing solvent-mediated transformations and catalytic effects, as these factors critically impact the final gel morphology and performance. Ongoing developments integrate large-scale parallelization, machine learning approximations, and enhanced sampling schemes to address the computational burdens associated with high-dimensional parameter spaces. At the same time, experimental validations inform rate constants and structural details, refining parameterization across broad pH regimes and temperature ranges. Despite these advances, open questions remain regarding the treatment of long-range interactions, rare-event kinetics, and the evolution of chemical equilibria over extended simulation times. This paper examines key achievements, limitations, and emerging trends in Monte Carlo investigations of silica gel networks, presenting a comprehensive and in-depth analysis of their current and future roles.

Development and Application of Refined Monte Carlo Algorithms for Understanding the Nucleation and Growth of Silicate Polymers under Varying Reaction Conditions
type: item
description: The exploration of silicate polymerization processes under diverse reaction conditions requires robust computational methods capable of capturing the intricacies of molecular association, oligomer formation, and extended network growth. Recent advances in stochastic algorithms, particularly those based on Monte Carlo principles, have enabled more predictive modeling of the nucleation and subsequent evolution of silicate-based frameworks. A refined treatment of monomer addition and oligomer reorganization steps—alongside an appropriate representation of reaction free energies and configurational states—provides deeper insight into emergent structural motifs. By incorporating systematic updates to conventional acceptance criteria and improving the sampling of intermediate chemical states, it is possible to more accurately monitor species size distributions and branching patterns during polymer growth. This paper presents an integrated approach that synthesizes established stochastic dynamics with new, condition-specific adaptions. Within this approach, the control of partial charge distributions, explicit tracking of steric constraints, and careful calibration of reaction probabilities allow for consistent agreement with experimentally inferred polymerization trends. The method is demonstrated across a range of supersaturation levels and pH values, leading to enhanced clarity on the mechanistic interplay of molecular assembling forces. Crucially, these results emphasize the necessity for algorithms that robustly adapt to the complexities inherent in inorganic polymerization, paving the way for targeted design and prediction of novel silicate materials.

Enhancing Data Security and Privacy in Cloud-based Big Data Systems: A Focus on Encryption and Access Control
type: item
description: Cloud-based big data systems offer vast storage and computational capabilities, yet they pose significant security and privacy risks. Encryption and access control mechanisms have emerged as key strategies for ensuring confidentiality, integrity, and availability within these environments. Implementing robust encryption approaches can protect data at rest, in transit, and during processing. Access control frameworks, on the other hand, enforce stringent rules governing data sharing and policy enforcement. The complexities introduced by large-scale data ingestion, geographically dispersed storage nodes, and dynamic real-time analytics necessitate advanced solutions that integrate seamlessly with the underlying cloud infrastructure. The blending of symmetric and asymmetric cryptographic algorithms, along with emergent techniques that allow computations on encrypted data, promises stronger protection without incurring excessive performance overhead. Fine-grained access control solutions, including dynamic role-based schemes and attribute-based systems, preserve data confidentiality while allowing data owners to share information in a flexible manner. This work explores mathematical approaches for modeling encryption schemes, formal definitions of security, and advanced key management techniques to fortify cloud-based platforms against a rapidly evolving threat landscape. It further discusses strategies for addressing scalability challenges, ensuring efficient computation, and aligning with stringent regulatory demands in diverse, multi-tenant environments. Emphasis is placed on proposing comprehensive methods that jointly integrate encryption and access control for sustainable, high-assurance cloud deployments.

Optimizing Collaborative Beamforming Strategies for Energy-Efficient Wireless Sensor Networks in Large-Scale IoT Deployments
type: item
description: This research presents a novel approach to collaborative beamforming optimization in large-scale Internet of Things (IoT) deployments, focusing on energy efficiency in wireless sensor networks (WSNs). We introduce a mathematical framework for analyzing the trade-offs between beamforming gain, energy consumption, and network lifetime in densely deployed sensor networks. Our methodology incorporates stochastic geometry to model random node distributions and develops closed-form expressions for expected beamforming gain under realistic channel conditions. We propose a distributed optimization algorithm that dynamically adjusts beamforming weights based on local energy constraints and global performance objectives. Extensive numerical simulations demonstrate that our approach achieves up to 43% improvement in energy efficiency compared to existing methods while maintaining comparable communication reliability. Field experiments conducted across three different environmental settings validate our theoretical findings, showing that the proposed collaborative beamforming strategy extends network lifetime by 37% while reducing transmission power requirements by 29% on average. We further analyze the scalability properties of our approach and characterize the fundamental limits of collaborative gain in the presence of synchronization errors and hardware imperfections. This work provides important insights for the design and deployment of energy-constrained IoT networks requiring long-term operation without human intervention.

Natural Language Processing Pipelines for Automated Knowledge Base Population: Applying Named Entity Recognition and Dependency Parsing
type: item
description: Natural language processing pipelines have become critical for automating knowledge base population, particularly through the integration of named entity recognition (NER) and dependency parsing. This paper presents a systematic framework for extracting structured knowledge from unstructured text by leveraging advances in sequence labeling, graph-based syntactic analysis, and probabilistic relational modeling. The proposed architecture combines bidirectional long short-term memory networks with conditional random fields to disambiguate entity boundaries and classify entities into predefined types under sparse and noisy textual conditions. Concurrently, a transition-based dependency parser augmented with attention mechanisms isolates grammatical relationships between entities, enabling the derivation of context-aware relational triples. A key innovation lies in the formulation of a joint optimization objective that aligns entity-relation pairs through tensor factorization, ensuring consistency between localized entity mentions and global knowledge graph semantics. Experiments demonstrate robustness to cross-domain syntactic variations and entity density fluctuations, achieving an F1 score of 92.3\% on entity typing and 88.7\% on relation extraction across multilingual benchmarks. The pipeline's computational complexity is analyzed through asymptotic bounds on graph traversal operations and entropy-regulated sampling strategies. This work establishes theoretical foundations for handling nested entity structures and discontinuous phrasal relations while maintaining linear time complexity relative to input sequence length, addressing critical scalability requirements for real-world knowledge base population systems.

Ontologies for Integrating and Querying Heterogeneous Data Sources in Semantic Web Applications: A Framework for Automated Knowledge Representation
type: item
description: This research paper presents a comprehensive framework for developing and implementing ontologies specifically designed to facilitate the integration and querying of heterogeneous data sources within Semantic Web applications. The proliferation of distributed data repositories with varying schemas, structures, and semantic contexts presents significant challenges for knowledge representation and access. Our approach introduces a novel three-tier ontological architecture that separates domain knowledge, schema mappings, and query interfaces into distinct but interconnected layers. We formalize the underlying theoretical foundations using Description Logic semantics (A LCH IQ) and demonstrate how this approach supports automated reasoning over disparate data sources while maintaining semantic consistency. Empirical evaluation across four domains (healthcare, financial services, geospatial systems, and scientific literature) demonstrates significant improvements in query completeness (27% average increase), precision (18% improvement), and computational efficiency (42% reduction in query execution time) compared to conventional single-ontology approaches. Additionally, we present a methodology for semi-automated ontology evolution to accommodate changing data sources and schemas. This framework provides a robust foundation for next-generation knowledge management systems that must operate across organizational and technological boundaries while preserving semantic integrity.

Big Data in Social Media Marketing: Analyzing Consumer Sentiment and Engagement Patterns
type: item
description: Big Data analytics has emerged as a critical tool in understanding consumer sentiment and engagement patterns, particularly within the fast-paced environment of social media marketing. Analyzing massive amounts of user-generated content—tweets, posts, comments, and reviews—enables businesses to capture nuanced insights into consumer preferences, intentions, and emotional states. This paper provides a technical exploration of how advanced data collection, preprocessing, and modeling methodologies can be leveraged to distill meaningful, actionable information from large-scale social media data streams. We address the complexities of processing heterogeneous data sources, including textual, visual, and behavioral signals, while discussing both classical and deep learning-based sentiment analysis frameworks. Moreover, we investigate how modeling engagement patterns—including likes, shares, and comments—can reveal network effects and viral propagation processes crucial to marketing success. Throughout, we integrate linear algebraic tools, such as matrix factorization and vector-based embeddings, highlighting their relevance in feature extraction and dimensionality reduction. The end goal is to outline a robust end-to-end pipeline—from data ingestion to interpretative modeling—that can guide the design of effective marketing strategies. By uniting statistical rigor with modern computational techniques, this paper underscores the pivotal role of Big Data in enabling precise targeting, real-time consumer feedback, and ultimately more effective social media marketing campaigns.

Optimizing Digital Advertising with Big Data: Analyzing Consumer Behavior for Real-Time Decision Making
type: item
description: Digital advertising has emerged as a pivotal driver of economic growth, catalyzed by the proliferation of big data technologies and evolving consumer engagement channels. Modern advertisers capitalize on real-time analytical tools to optimize campaigns, measure effectiveness, and predict consumer behavior with unprecedented precision. This paper explores an integrative framework that harnesses big data for digital advertising, emphasizing strategies to interpret and leverage consumer behavioral insights for adaptive, data-driven decision making. By combining granular user data from diverse online and offline sources with advanced machine learning models, advertisers can identify and act upon micro-level consumer trends. In particular, this research illustrates the utility of real-time bidding infrastructures and dynamic budget allocations tailored to multichannel environments. We evaluate various data modeling techniques that incorporate both latent and explicit consumer signals, offering a path to more efficient segmentation and personalization. Additionally, we discuss methods for mitigating computational bottlenecks that arise from large-scale data processing, focusing on distributed architectures and parallelizable algorithms. Ultimately, the paper highlights how data-driven optimization strategies can refine creative content, brand messaging, and campaign performance across digital platforms. The overarching aim is to demonstrate how big data can transform digital advertising into a predictive, reactive, and contextually-aware ecosystem, driving superior return on investment and enhanced consumer engagement.

Evaluation of Quantitative and Qualitative Metrics for Assessing Hallucination Phenomena in Large Language Models
type: item
description: Hallucination phenomena in large language models have drawn considerable attention due to their impact on reliability, trustworthiness, and interpretability. Recent advances in transformer-based architectures have demonstrated remarkable capabilities in tasks such as language generation, question answering, and dialogue systems. However, the incidence of fabricated details during inference raises concerns regarding the internal mechanisms that guide these models toward erroneous responses. Uncertainties inherent in model training and data representation create conditions in which hallucinated elements appear, often veiled by fluency and coherence that obscure their inaccuracy. Researchers have proposed numerous strategies to identify and evaluate these outputs, leading to the emergence of a broad array of quantitative and qualitative metrics. Quantitative measurements focus on numerical or probabilistic characterizations, reflecting the extent to which token distributions deviate from reference truths. Qualitative assessments emphasize the interpretive dimension, shedding light on user perceptions, contextual expectations, and semantic coherence. This paper provides a systematic evaluation of these methodologies by examining different metric families, highlighting the conditions under which each approach offers robust insights into generative behavior. The synthesis presented here reveals methodological distinctions, reveals synergies among multiple evaluation frameworks, and showcases promising analytical pathways for furthering the accurate interpretation of model outputs. An integrated perspective on hallucination assessment could guide principled development and deployment of reliable language models.

Distributed Sensor Integration for Drone-V2X Collaboration Aimed at Persistent Connectivity in Constrained Road Networks
type: item
description: Distributed sensor arrays harness multi-modal data from unmanned aerial vehicles (UAVs) and roadside units to facilitate collaborative vehicle-to-everything (V2X) communication in constrained transportation networks. Drone-based platforms with embedded imaging, acoustic, and environmental sensors enhance situational awareness for on-road vehicles, enabling proactive congestion management and optimized navigation under suboptimal connectivity conditions. Connectivity challenges on narrow or obstructed corridors are addressed by deploying UAVs as airborne relays that gather road traffic data, meteorological readings, and infrastructure status from multiple vantage points. This data is relayed to ground-based vehicles in near real-time, yielding continuous route planning updates and minimizing disruptions caused by blind spots and signal blockages. The integration of distributed sensor nodes with advanced communication protocols, including millimeter-wave and cellular vehicle-to-everything (C-V2X) technologies, permits more robust pathfinding and distributed decision-making. Machine learning-driven analytics further enrich situational intelligence by fusing information streams from heterogeneous sensors, thereby enabling predictive capacity for event detection such as accidents, extreme weather, or fluctuations in traffic density. This paper explores the architectural dimensions of drone-V2X sensor integration, network protocols for real-time data sharing, resource allocation for seamless connectivity, and a simulated experimental analysis of the approach on constrained road segments. Findings indicate improved service continuity, prompt event detection, and enhanced safety outcomes when drones and ground vehicles engage in tightly coordinated and sensor-augmented interactions.

Reinforced Navigation Protocols Using Aerial Surveillance and V2X Analytics for Complex Tunnel Systems
type: item
description: Reinforced navigation protocols in complex tunnel systems rely on robust data exchanges and real-time environmental interpretation. Implementation of aerial surveillance in tandem with vehicle-to-everything (V2X) analytics enhances situational awareness, especially where GPS signals are weak or interrupted. Deploying drone fleets, equipped with specialized sensors, supports dynamic mapping and identification of emerging obstructions, thereby enabling rapid adaptation of navigation pathways. Communication between vehicles, infrastructure, and aerial units relies on consistent data standards and unified access to cloud-based analytics platforms. Integration of environmental parameters, such as air quality and traffic density, fortifies decision-making processes for route optimization and safety. Incorporation of cooperative maneuvers among drones and ground vehicles facilitates timely responses to congestion, construction, or other unforeseen disruptions. V2X channels ensure immediate distribution of navigation updates, which mitigates hazards such as vehicle pileups and extended traffic delays. Predictive models built upon machine learning algorithms refine routing calculations, reflecting time-sensitive data streams collected across the entire tunnel environment. Reinforcement of these protocols through distributed and redundant sensing fosters reliability, as well as improved autonomy for advanced driver-assistance systems. The proposed framework thus expands the potential of intelligent transportation networks, linking aerial assets with terrestrial entities in order to streamline navigation, reduce travel times, and maintain high safety standards in complex tunnel corridors.

description: E-retail ecosystems rely on cloud-native technologies, continuous integration, and continuous delivery to maintain competitiveness and meet shifting consumer expectations. DevOps methodologies enhance collaboration between development and operations teams, but traditional approaches to security and compliance become difficult to sustain when release cycles accelerate. Integrating security measures and regulatory requirements into DevOps pipelines yields cohesive, proactive defenses that adapt to new threats. E-retail systems that manage high volumes of customer data, transactions, and third-party services face stringent obligations to protect privacy and financial information. Strong identity management, network segmentation, and automated policy enforcement reduce the risk of data breaches, while granular monitoring and observability enhance real-time threat detection. Compliance frameworks, such as payment security standards and data protection regulations, intersect with DevOps workflows, requiring thorough documentation, audit trails, and role-based access controls. This paper evaluates how Secure DevOps principles unify operational agility with mandatory compliance practices in public and hybrid cloud environments. Five sections detail the evolution of cloud e-retail, discuss unique compliance requirements, identify key DevOps security elements, explore the automation of security gates within pipelines, and examine strategies for sustainable, future-proofed e-retail solutions. The synthesis underscores that integrated security and compliance bolster confidence in e-retail platforms, allowing frequent releases that remain stable, user-centric, and impervious to malicious disruptions.

Tokenization Techniques and Their Effect on Risk Reduction for Payment Data in Serverless E-Commerce Frameworks
type: item
description: Tokenization significantly mitigates security and compliance challenges that arise when handling payment data in serverless e-commerce frameworks. Serverless architectures distribute functional responsibilities into ephemeral services, obviating the need for traditional server management while accelerating feature releases and scaling. Yet this decomposition increases potential attack surfaces, particularly for payment data traversing multiple microservices and vendor-provided functions. Tokenization replaces sensitive cardholder data with randomly generated substitutes, known as tokens, ensuring that external systems and internal components remain insulated from raw financial information. This methodology addresses privacy, regulatory, and reputational concerns, offering a streamlined strategy for payment integrity and data devaluation. Implementations rely on secure vaults or third-party tokenization providers, complemented by secure APIs that regulate token issuance, storage, and usage. Automated serverless workflows and event-driven triggers further amplify the benefits of tokenization by limiting direct exposures to sensitive inputs and outputs. High-velocity e-commerce pipelines benefit from consistent token generation and de-tokenization mechanisms, preventing raw data from ever persisting in logs or ephemeral storage. The ensuing sections examine the core principles of tokenization, elaborate on architectural implementations in serverless e-commerce scenarios, evaluate risk reduction and compliance strategies, and present forward-looking perspectives on how tokenization can unify payments security with modern, composable application designs. Five detailed sections highlight the synergy between token-based security models and the dynamic, scalable nature of serverless e-commerce, culminating in pragmatic recommendations for robust payment data protection.
