Event-Driven Architecture for Customer Engagement Automation and Secure Multi-Cloud Data Exchange in Salesforce.

Sathishkumar Periyasamy

Read Abstract

Event-driven architecture constitutes a software design paradigm through which systems establish communication channels and generate responses to modifications via event mechanisms, rather than depending upon direct synchronous request protocols such as Application Programming Interfaces. This architectural pattern possesses the capability to manage customer interaction activities at real-time scales and substantial operational volumes through the delivery of personalized, temporally appropriate, and contextually relevant engagements spanning multiple communication channels, including electronic mail, short message services, push notification systems, conversational interfaces, and social media platforms. Through decoupling of operational processes and enabling instantaneous communication pathways connecting Marketing Cloud, Sales Cloud, Service Cloud and other external cloud platforms like MuleSoft, Tableau, AWS, Azure, and Google Cloud Platform, organizations acquire the capacity to construct scalable workflow systems that generate automatic responses to customer behavioral actions, such as product viewing activities or shopping cart abandonment scenarios. The architectural framework produces measurable improvements in customer responsiveness metrics, diminishes requirements for manual follow-up procedures, and guarantees seamless coordination among organizational teams while avoiding the introduction of rigid coupling relationships between system components. When multiple systems, particularly cloud-based infrastructures, exchange information through Application Programming Interface channels involving sensitive customer information, payment transaction details, or critical business process data, securing these interfaces becomes paramount for protecting information assets, guaranteeing that exclusively authorized users and systems maintain access privileges, and preventing unauthorized exploitation. Secure multi-cloud exchange architectures can be designed employing OAuth 2.0 authentication frameworks, encryption protocol implementations, and event-based notification mechanisms while maintaining compliance with privacy regulatory frameworks such as the General Data Protection Regulation or the Health Insurance Portability and Accountability Act.

An Analytical Assessment of Transitioning Traditional Enterprise Computing Systems into On-Demand Digital Ecosystems

Jean-Baptiste Mbuyi Kalenga

Read Abstract

Digital The rapid evolution of digital technologies has transformed enterprise computing from static, infrastructure-centric environments into dynamic, service-oriented digital ecosystems. Organizations increasingly recognize that traditional enterprise computing systems, characterized by monolithic architectures, high capital expenditure, limited scalability, and complex maintenance requirements, are insufficient for supporting modern business innovation and digital transformation. The emergence of cloud computing, virtualization, Internet of Things (IoT), artificial intelligence, machine learning, and software-defined infrastructure has enabled organizations to transition toward on-demand digital ecosystems that provide scalable, flexible, and resilient computing capabilities. However, this transition presents numerous technical, organizational, economic, and cybersecurity challenges that require comprehensive analytical assessment before implementation.

This research paper critically examines the transition from traditional enterprise computing systems to on-demand digital ecosystems by synthesizing existing academic literature and analysing technological, operational, and security dimensions associated with digital transformation. The study adopts a qualitative review-based analytical methodology using the selected scholarly references to investigate migration drivers, enterprise architecture evolution, cloud-enabled service models, cybersecurity implications, machine learning-based intrusion detection mechanisms, and organizational transformation strategies. The paper further evaluates the relationship between digital ecosystem development and emerging intelligent security mechanisms capable of protecting distributed enterprise infrastructures from increasingly sophisticated cyber threats.

The findings indicate that successful enterprise transformation extends beyond technology migration and requires strategic alignment among business objectives, governance frameworks, security architecture, organizational readiness, and continuous innovation capabilities. Cloud computing significantly improves scalability, operational efficiency, service availability, and resource optimization, while machine learning-based intrusion detection enhances security resilience in distributed environments. Nevertheless, migration complexity, legacy system integration, regulatory compliance, vendor dependence, and organizational change management remain substantial implementation challenges. The study also demonstrates that effective migration strategies involve phased modernization approaches, hybrid deployment models, and intelligent security frameworks capable of adapting to evolving digital environments. Comparative insights regarding legacy-to-cloud migration further reinforce the importance of structured migration planning and enterprise readiness assessment (Joshi, 2025).

The paper contributes to contemporary enterprise computing literature by integrating technological, organizational, and cybersecurity perspectives into a unified analytical framework for digital ecosystem transition. The study provides practical guidance for organizations planning digital modernization while identifying future research opportunities involving autonomous cloud management, intelligent security orchestration, and AI-driven enterprise governance.

The Unclear Mandate: Managerial Tensions in Large Scale Agile Transformations — A Structured Literature Review

Yogesh Sabnis

Read Abstract

In many large enterprises, scaling agile has become a central part of broader digital transformation efforts. While the benefits of agile at the team level are well documented, the role of managers, particularly those in middle management, remains conceptually underdeveloped and practically ambiguous. This paper presents a structured review of 15 recent studies on large scale agile transformations published between 2019 and 2025. The synthesis identifies four recurring domains of managerial tension. These domains are leadership and authority, decision making and governance, coordination and integration, and performance and sustainability. The analysis interprets these tensions as paradoxes that require managers to reconcile autonomy with control, short term delivery with long term capability building, and local experimentation with enterprise stability. Drawing on paradox theory and dynamic capabilities, the paper develops a conceptual framework that positions middle managers as brokers of paradox across organizational levels. The framework contributes to scholarship by integrating fragmented evidence on managerial work in agile transformations and by extending paradox theory into the context of large scale agile. For practitioners, it offers a lens for redesigning leadership development, governance arrangements, and performance systems so that managers are better equipped to sustain agility over time.

Holistic Pricing: Going beyond elasticity models by merging datasets through data fusion and interoperability

Nathan Isaac Suchar Ponte

Read Abstract

This paper addresses the basic issues with using classical Price Elasticity of Demand (PED) models for commercial applications, particularly due to their inability to apply effective constraints under dynamic market conditions. Classical models usually lead to theoretically optimal, but impractical price recommendations (e.g. unlimited price increases for inelastic goods). This study proposes the Holistic Pricing Approach (HPA), a multi-variable method that unifies data inputs from multiple sources into a single recommendation engine that helps overcome the classical model shortcomings.

The HPA method employs a data fusion system linking three unique data sources: internal economics (e.g., product cost, target gross margins), competitive intelligence (competitor’s prices) and macroeconomic factors (e.g., inflation). These inputs are standardized with an interoperability layer to drive a four-step algorithmic heuristic. This includes a margin anchor price that is subject to adjustments by “competitive boundary checks” and “volume guardrails” to avoid excessive demand erosion.

The effectiveness of the HPA was validated through a theoretical simulation with truncation that was compared to a classic elasticity model. The results showed that the traditional approach maximized margin at the expense of significant volume (20% lost), while HPA successfully balanced preserving margins and market share (5% volume loss). Furthermore, the total profit dollar amount was greater for the HPA strategy, which confirms that the HPA methodology drives increasing economic value.

This study demonstrates that to protect revenue integrity, pricing must be approached as an interoperable ecosystem of constraints rather than a single dimensional elasticity calculation. This approach offers a roadmap for business leaders who, in the face of inflation, need to strike the right balance between increasing prices and preserving market share.

Dr. Neha Kulkarni

Read Abstract

Agricultural financing systems remain constrained by inefficiencies arising from fragmented data infrastructures, manual processing, and limited integration between stakeholders. These constraints impede timely credit delivery, increase operational risk, and restrict financial inclusion among agricultural enterprises. This study investigates the role of client management systems, particularly Customer Relationship Management (CRM) platforms, in transforming agricultural financing operations through process optimization, data integration, and intelligent decision support.

The research adopts a technical and analytical approach, synthesizing insights from existing literature on CRM systems, agricultural finance, risk modeling, and artificial intelligence. It develops a structured framework that integrates client management platforms with credit evaluation mechanisms, workflow automation, and predictive analytics. The study emphasizes how CRM-enabled architectures facilitate centralized data management, enhance customer profiling, and enable dynamic credit scoring aligned with agricultural risk variables such as climate conditions and seasonal fluctuations.

Findings indicate that CRM-driven financing operations significantly reduce processing time, improve credit risk assessment accuracy, and enhance customer engagement. The integration of machine learning models and decision-support algorithms enables financial institutions to evaluate borrower profiles more effectively, thereby reducing default risks and improving resource allocation. Furthermore, CRM systems support real-time monitoring and compliance management, ensuring regulatory adherence and operational transparency.

However, the implementation of client management systems in agricultural finance presents challenges, including infrastructure limitations, data quality issues, and resistance to technological adoption. The study highlights the importance of system customization, stakeholder alignment, and technological readiness in overcoming these barriers.

This research contributes to the field by proposing a comprehensive, technology-driven model for agricultural financing operations. It provides actionable insights for financial institutions, policymakers, and agribusiness stakeholders seeking to enhance efficiency and sustainability in agricultural credit systems. The study underscores the transformative potential of client management systems in bridging the gap between traditional financing practices and modern digital ecosystems.

MD NAD VI AL BONY

Read Abstract

Accurate forecasting and effective risk assessment are critical components of modern business decision-making. With the rapid growth of data availability and computational power, machine learning (ML) has emerged as a powerful tool for improving predictive accuracy across diverse business domains. This study presents a cross-domain analysis of commonly used machine learning models for business forecasting and risk assessment, focusing on their applicability, performance, and limitations in different contexts. The research examines supervised learning models—including linear regression, decision trees, random forests, support vector machines, and neural networks—across financial forecasting, credit risk assessment, demand prediction, and operational risk management. Using secondary datasets and prior empirical findings, the study compares model performance based on prediction accuracy, interpretability, scalability, and robustness. The analysis highlights that while complex models such as neural networks and ensemble methods often achieve higher predictive accuracy, simpler models retain importance due to their transparency and ease of implementation. Furthermore, the study emphasizes that no single machine learning model is universally optimal; rather, model effectiveness depends on domain characteristics, data quality, and business objectives. The findings contribute to the growing literature on applied machine learning by offering a structured framework for selecting appropriate models across business domains. This research provides practical insights for managers, analysts, and policymakers seeking to integrate machine learning into forecasting and risk assessment processes while balancing performance and interpretability.

Chaos Engineering as a Learning Framework: A Human-Centered Model for Developing High-Reliability Engineering Teams

Sagar Kesarpu

Read Abstract

Chaos Engineering has conventionally been seen as a technical field dedicated to introducing controlled errors into distributed systems to identify vulnerabilities and enhance system resilience. This system-centric perspective has yielded considerable progress in cloud-native reliability; however, insufficient focus has been directed towards the human aspect of resilience engineering—particularly, how chaos experimentation can enhance learning, bolster cognitive preparedness, and fortify the competencies of engineering teams functioning amidst uncertainty. This study presents a Human-Centered chaotic Engineering (HCCE) Model, an innovative framework that reconceptualizes chaotic experiments as organized learning interventions instead of merely system stressors. Utilizing concepts from resilience engineering, DevOps culture, Site Reliability Engineering (SRE), and experiential learning theory, the proposed model identifies chaos experiments as tools to improve mental frameworks regarding failure, decrease incident response time, cultivate an antifragile team culture, and strengthen rapid decision-making. This paper illustrates, via case studies from enterprise DevOps and SRE Dojo programs, how chaos-driven learning settings promote psychological safety, facilitate collaborative problem-solving, and cultivate engineers who are not merely system operators but practitioners of resilience. The research posits that the forthcoming advancement in Chaos Engineering is not solely in automating fault injection or enhancing observability, but in fostering high-reliability teams adept at anticipating, adapting to, and learning from disruptions. The findings present a distinct viewpoint that integrates sociotechnical systems theory with practical enterprise engineering, establishing Chaos Engineering as a transformative educational framework for contemporary software organizations.

Convergence of Industrial Risk Prevention and Cybersecurity Governance: A Multi-Dimensional Policy Framework for Systemic Resilience and Compliance

Dr. Julian Thorne

Read Abstract

This research article explores the critical intersections between industrial risk prevention and modern cybersecurity governance, arguing that the silos separating physical safety from digital security are increasingly obsolete in the face of systemic global threats. By examining the regulatory evolution following catastrophic industrial events-specifically the Lubrizol factory fire in France-and the surge in complex cybercrimes such as the Salt Typhoon and Medibank hacks, the study identifies a pervasive gap in integrated risk frameworks. The research synthesizes the French "major risk prevention" approach with international IT audit frameworks (ITAF) and strategic cybersecurity compliance models. It utilizes a comparative analysis of risk policy tools in Normandy, Piedmont, and Victoria to demonstrate that current methodologies remain overly hazards-focused rather than vulnerabilities-focused. Furthermore, the study investigates the role of third-party vendor risks and the necessity of multi-factor authentication (MFA) as fundamental pillars of organizational resilience. By proposing a "Strategic Cybersecurity Governance" model, this article provides a roadmap for aligning technological protection with legal compliance. The findings suggest that systemic resilience requires a shift from reactive post-accident regulation toward proactive, blockchain-enhanced financial privacy and comprehensive auditing strategies. This article contributes a deep theoretical elaboration on the "chronic crisis" of industrial safety and the emerging challenges of cyber-physical integration, providing a publication-ready synthesis for researchers and policymakers.

Intelligent Cloud Automation: A Framework for Enterprise-Scale Infrastructure Management

Suresh Kumar Maddali

Read Abstract

Modern enterprises face critical challenges in managing cloud infrastructure at scale, where traditional manual approaches create bottlenecks that impede innovation and introduce operational risks. This article presents a comprehensive examination of an intelligent operations framework designed to address these challenges through serverless orchestration, automated discovery, and integrated governance mechanisms. The framework leverages event-driven architectures and infrastructure as code principles to transform infrastructure management from error-prone manual processes into automated, self-managing systems that deliver consistent outcomes across hybrid and multi-cloud environments. By embedding security and compliance capabilities throughout the automation platform rather than treating them as afterthoughts, the framework establishes comprehensive governance while maintaining operational agility. The article explores architectural foundations built on serverless technologies that minimize infrastructure overhead while maximizing scalability, dynamic asset discovery engines that maintain real-time inventory across distributed cloud environments, and modular workflow implementations spanning provisioning, maintenance, and access management. Integration with enterprise authentication systems ensures all automated actions remain properly authorized and auditable, while continuous compliance monitoring enables proactive remediation of policy violations. The framework incorporates sophisticated observability capabilities encompassing metrics, logs, and distributed traces to provide comprehensive visibility into both infrastructure health and automation performance. Through rigorous testing practices and careful orchestration of deployment phases, the framework balances security responsiveness with operational stability while addressing persistent challenges in identity management, configuration drift detection, and policy enforcement across heterogeneous cloud platforms.

Governing Infrastructure as Code in Multi-Cloud Enterprises: Integrating Data Governance, MLOps, and Corporate Governance for Secure and Sustainable Digital Transformation

Alejandro M. Ríos

Read Abstract

The accelerating diffusion of multi-cloud strategies across large enterprises has radically transformed how digital infrastructures are designed, governed, and operated. At the heart of this transformation lies Infrastructure as Code (IaC), a paradigm that converts physical and virtual infrastructure into software-defined, version-controlled, and automatically deployed assets. While the technical efficiencies of IaC are now widely acknowledged, its governance, risk, compliance, and organizational implications remain theoretically underdeveloped and empirically fragmented. This article develops an integrated research framework that positions IaC as a central organizational control mechanism in multi-cloud ecosystems, linking it to data governance, MLOps, and corporate governance theory. Drawing on the best-practice architecture for enterprise multi-cloud deployments articulated by Dasari (2025), this study extends the concept of IaC beyond operational automation and situates it as a core instrument of institutional governance, risk mitigation, and strategic alignment.

The article synthesizes insights from contemporary data governance scholarship, MLOps pipeline research, and corporate governance theory to explain why IaC has become a pivotal governance technology in modern enterprises. From a data governance perspective, the article argues that IaC enables auditable, reproducible, and policy-enforced data infrastructures, thereby reducing data quality risks and legal exposure in highly regulated environments (Bernardo et al., 2024; Nag, 2024). From an MLOps perspective, IaC forms the infrastructural backbone of continuous machine learning pipelines, enabling controlled experimentation, reproducibility, and model lifecycle governance across heterogeneous cloud platforms (Google Cloud, 2024; Steidl et al., 2023). From a corporate governance perspective, IaC is theorized as a technological codification of organizational rules, analogous to governance codes that align managerial behavior with stakeholder interests (Aguilera & Cuervo-Cazurra, 2009; Larcker& Tayan, 2011).

Methodologically, this article adopts a theory-building design grounded in systematic literature integration and analytical synthesis. Rather than relying on statistical datasets, it constructs a conceptual model that connects multi-cloud complexity, infrastructural codification, and governance outcomes. The analysis demonstrates that enterprises adopting IaC in line with the architectural and procedural best practices identified by Dasari (2025) achieve superior transparency, reduced operational risk, and stronger alignment between IT execution and corporate governance objectives. The findings reveal that IaC does not merely automate infrastructure; it institutionalizes organizational intent into executable code, transforming governance from a human-centric compliance process into a continuous, machine-enforced system of control.

The discussion advances a new theoretical proposition: that IaC constitutes a form of “algorithmic governance” within the enterprise, bridging the gap between corporate governance codes and operational reality. This perspective explains why organizations with mature IaC capabilities are better positioned to manage regulatory compliance, data sovereignty, and ethical AI obligations in multi-cloud environments. The article concludes by outlining future research pathways for examining IaC as a governance institution, calling for empirical studies that link IaC maturity to financial performance, risk resilience, and organizational legitimacy.

High-Fidelity Speech Reconstruction Employing Quality Assessment Functions and Optimization Procedures

Dr. Somchit Phanthavong

Read Abstract

High-fidelity speech reconstruction has emerged as a fundamental requirement in modern communication systems, intelligent multimedia platforms, hearing assistance technologies, forensic audio analysis, and remote collaboration infrastructures. The increasing dependence on compressed and noisy speech transmission environments has intensified the demand for robust enhancement methodologies capable of preserving intelligibility, perceptual quality, and spectral fidelity. Conventional filtering approaches often suffer from residual noise amplification, spectral distortion, and inadequate adaptation to dynamic acoustic environments. Consequently, optimization-driven quality enhancement strategies have become increasingly significant in speech engineering research. This study proposes an integrated computational framework for high-fidelity speech reconstruction employing quality assessment functions and optimization procedures. The framework combines Linear Quality Estimation (LQE), adaptive spectral refinement, multi-objective particle swarm optimization, support vector data description, and statistical quality control mechanisms to improve speech enhancement performance under varying degradation conditions.

The proposed architecture incorporates feature-domain optimization and perceptual quality assessment into a unified reconstruction pipeline. Quality estimation metrics are used to evaluate spectral consistency, temporal smoothness, and perceptual speech clarity. Optimization procedures dynamically adjust enhancement parameters to minimize distortion while maximizing speech intelligibility. Multi-objective optimization strategies improve convergence stability and adaptive response across fluctuating noise profiles. Statistical process monitoring further ensures reconstruction reliability through anomaly detection and quality regulation. Deep-learning-assisted abnormal signal analysis is integrated to enhance robustness against unpredictable acoustic variations.

The study analytically evaluates the effectiveness of optimization-guided speech reconstruction using theoretical modeling, comparative algorithmic interpretation, and performance-oriented quality analysis derived exclusively from the provided literature. The framework demonstrates significant improvements in reconstructed speech consistency, adaptive filtering precision, and perceptual fidelity. Findings indicate that optimization-supported quality evaluation substantially reduces spectral degradation and enhances reconstruction stability compared with conventional enhancement methodologies. The proposed model also supports scalable deployment in telecommunications, medical communication systems, assistive speech technologies, and intelligent multimedia infrastructures.

The research contributes a comprehensive interdisciplinary framework that integrates speech enhancement theory, optimization intelligence, statistical quality control, and perceptual assessment methodologies. By synthesizing quality estimation functions with adaptive optimization mechanisms, the study establishes a scalable foundation for next-generation speech reconstruction systems operating within complex acoustic environments.

RAG for Smarter Resume Analysis: Beyond Basic LLMs

Igor Zuykov

Read Abstract

The article examines an architectural approach to resume analysis based on Retrieval-Augmented Generation (RAG), designed to overcome the systemic limitations of traditional keyword-matching algorithms (like TF-IDF and BM25) and the inherent constraints of large language models (LLMs) used in isolation under conditions of an overloaded and semantically heterogeneous hiring market. The relevance of the work is driven by the growth in the volume and variability of resumes, the need to capture latent semantic correspondences between experience phrasing and vacancy requirements, and the risks of algorithmic biases, as well as the plausible yet unreliable generation of personnel decisions. The study aims to formalize a dual-loop scheme for processing a resume corpus, in which dense semantic retrieval over vector representations of document fragments is coupled with answer generation strictly constrained by the retrieved context and complex refusal rules under insufficient grounds. The scientific novelty lies in interpreting the RAG approach as a mechanism of search-based non-parametric memory for a corporate resume array, where the chunking strategy (determined at the ingestion phase) and the retrieval parameters such as topK and similarity. Threshold, directly governing the scope and quality of information passed to the retrieval act as controllable regulators of the recall–noise–cost trade-off, and where requirements for explainability, traceability, and privacy are derived from HR-specific constraints rather than declared post factum. It is demonstrated that separating retrieval and generation functions, offloading compute-intensive corpus preparation into an asynchronous loop, and locally deploying models jointly reduce LLM load, decrease the incidence of hallucinations, and enable verifiable candidate ranking based on the semantic proximity of the experience to the recruiter’s query. It is concluded that the reliability of systems of this class is determined not by model strength, but by the architecture of source control and the discipline of context management. The article will be helpful for researchers and engineers developing intelligent talent selection systems, as well as for practicing recruiters and HR analysts implementing RAG solutions in corporate processes.

Integrated Thermal-Electrical Co-Optimization Architecture for Electric Vehicle Battery Systems: Advanced Refrigerant-Based Cooling, Active Cell Balancing, And Intelligent Distributed Management

Dr. Elena Markovic

Read Abstract

The rapid electrification of transportation has intensified research into high-performance battery systems capable of meeting stringent safety, durability, and efficiency requirements. Thermal instability, cell imbalance, and management complexity remain key constraints in lithium-ion battery packs for electric vehicles (EVs). This study proposes and analytically evaluates an integrated thermal-electrical co-optimization architecture that combines refrigerant-based direct battery cooling, advanced active cell balancing topologies, and distributed battery management system (BMS) communication strategies. Drawing strictly from prior foundational works in refrigerant-based thermal systems, switched-capacitor and resonant converter equalizers, modular BMS architectures, electrochemical safety modeling, grid-scale storage analysis, and intelligent cloud-enabled battery optimization frameworks, this research synthesizes a unified conceptual and operational model. The methodology integrates descriptive electro-thermal modeling, topology-based balancing performance assessment, and distributed communication reliability evaluation in large-scale battery strings. Results indicate that direct refrigerant cooling, when coordinated with resonant or switched-capacitor equalization and monitored via high-bandwidth distributed BMS protocols, significantly enhances thermal uniformity, reduces voltage dispersion, and mitigates safety risks. Furthermore, intelligent optimization layers leveraging cloud-based analytics demonstrate potential for predictive energy management and failure detection. The findings highlight the interdependence of thermal regulation, charge equalization dynamics, and communication latency in determining overall pack longevity and safety. Limitations related to implementation complexity and system cost are critically examined. The study concludes by outlining pathways for next-generation EV battery architectures that harmonize thermal control, electrical balancing, and digital intelligence within scalable and safety-oriented frameworks.

Numerical Analysis of Vibroacoustic Loads on Composite Payload Fairings of Launch Vehicles: A Review of Methods and Approaches

Khamlak Maryna

Read Abstract

The paper surveys numerical practices used to predict and mitigate vibroacoustic loads inside composite payload fairings across liftoff and early ascent. Novelty lies in a unified mapping between exterior-source solvers and interior structure–cavity models, linking unsteady RANS for launch-pad environments with FE–SEA backbones, transfer-matrix screening for multilayer curved shells, and FE–BEM spot checks. The review compares transmission-control options suitable for composite structures, including locally resonant liners, partial porous fills, micro-perforated hierarchical sandwiches, and high-intensity nonlinear stacks, against mass and manufacturability constraints.

Special attention is given to deflector-induced source shaping, coherence-preserving load transfer, and parameter identification for blanket and liner impedances. The objective is to distill a staged workflow that reconciles accuracy with design-cycle cost while sustaining qualification margins for avionics. Methods include comparative synthesis, model-taxonomy analysis, and normalization of reported vibroacoustic metrics to one-third-octave SPL and transmission loss.

Because vibroacoustic qualification margins are mission-critical for launch vehicles, and because composite fairings represent an area of engineering central to the aerospace sector, these modeling strategies support industry reliability in advanced structural–acoustic design.

Predictive Maintenance Framework for Electric Bus Braking Systems Based on Regenerative Braking Data Analytics

Asanov Seyran

Read Abstract

Electric buses use regenerative braking a lot to make them more energy-efficient and lower the amount of particles they release into the air. This means that friction braking parts are used less often. This change makes brake parts last longer, but it also changes the thermal cycles and wear patterns, which can cause corrosion, uneven wear, and problems with braking performance that regular maintenance schedules based on time or mileage can't fix. This paper suggests a way to use high-resolution telematics and machine-learning techniques to predict when friction brakes in electric buses will need maintenance. We process operational data like regenerative and hydraulic braking signals, deceleration behavior, thermal cycles, state-of-charge limits, and passenger load estimates to create a Brake Wear Index and train hybrid models that use both Random Forest and LSTM architectures with Weibull reliability estimation. Results show that wear prediction accuracy has improved and that there are up to 40% fewer unplanned maintenance events than with scheduled maintenance methods. The results show how important it is to use regenerative-aware diagnostic analytics to make sure that electric buses run safely, cheaply, and reliably in urban transport networks.

Reimagining Cloud Data Warehousing Through Serverless Orchestration: A Redshift-Centric Framework For Elastic, Cost-Optimized Analytics

Dr. Oscar Villareal

Read Abstract

Modern organizations increasingly confront a dual imperative: to extract high-value analytical insight from exponentially growing data volumes while simultaneously containing the spiraling operational and capital expenditures associated with cloud infrastructure. This tension has produced a new generation of data-intensive architectures that merge cloud data warehousing, serverless computing, and event-driven orchestration. Among these, Amazon Redshift–centered ecosystems have emerged as a dominant paradigm for large-scale analytics, yet their economic, architectural, and performance implications remain under-theorized when integrated with contemporary serverless platforms. Building on the design patterns, optimization strategies, and practical recipes documented in Amazon Redshift Cookbook (Worlikar, Patel, & Challa, 2025), this article develops a comprehensive analytical framework that situates Redshift within the broader scholarly discourse on cloud-native and function-as-a-service (FaaS) systems. By synthesizing insights from virtualization research, cost-optimization studies, auto-scaling theory, and stateful serverless architectures, the paper argues that Redshift is no longer merely a static analytical warehouse but a dynamic, programmable analytical substrate capable of being orchestrated through ephemeral compute units.

The results of this synthesis demonstrate that Redshift-based serverless analytics pipelines can significantly reduce idle resource costs and improve operational agility, but they also introduce new forms of architectural fragility related to orchestration complexity and state management. The discussion section situates these findings within longstanding debates on cloud efficiency, the limits of auto-scaling, and the future of data-centric computing. It concludes that Redshift’s evolution into a serverless-friendly analytical core represents a paradigmatic shift in how data warehouses are conceptualized, transforming them from monolithic systems into flexible participants in distributed, event-driven ecosystems. This shift has profound implications for both researchers and practitioners seeking to design sustainable, high-performance cloud data platforms.

Read Abstract

The rapid digital transformation of financial institutions has increased the demand for secure, scalable, and compliant platforms that can support advanced analytics and artificial intelligence (AI). Salesforce Hyperforce, a cloud-native re-architecture of the Salesforce platform, enables enterprises to leverage public cloud infrastructure while meeting regulatory and performance requirements. This paper examines how Hyperforce facilitates AI and analytics adoption in financial services by enabling elastic compute, real-time data integration, and seamless connections with data warehouses such as Snowflake and BigQuery. It evaluates architectural patterns, compliance considerations, and case studies where Hyperforce drives financial insights, fraud detection, and personalized banking experiences.

The increasing reliance on data-driven decision-making in financial services has intensified the demand for platforms that can seamlessly support advanced analytics and artificial intelligence (AI) while maintaining regulatory compliance and operational resilience. Salesforce Hyperforce, a cloud-native re-architecture of the Salesforce platform, addresses these needs by deploying Salesforce services on hyperscaler infrastructures such as AWS, Azure, and Google Cloud. By enabling data residency controls, elastic compute capabilities, and enhanced integration options, Hyperforce creates a robust foundation for financial institutions to harness AI and analytics at scale.

This paper explores how Hyperforce empowers banks and financial organizations to unlock real-time insights by integrating seamlessly with modern data ecosystems, including Snowflake, BigQuery, and AI/ML frameworks. It highlights use cases such as fraud detection, customer personalization, risk assessment, and regulatory reporting—areas where the convergence of Hyperforce infrastructure and AI-driven analytics generates measurable business value. Furthermore, the study evaluates architectural patterns, data governance models, and compliance strategies critical for adopting Hyperforce in highly regulated financial environments.

Through a combination of technical analysis and real-world case studies, this work demonstrates that Salesforce Hyperforce is not only an enabler of cloud-scale CRM but also a strategic platform for financial analytics innovation. By leveraging cloud-native infrastructure, institutions can achieve faster time-to-insight, enhanced scalability, and improved resilience while maintaining customer trust and adherence to stringent regulatory frameworks. The findings suggest that Hyperforce, when aligned with AI and analytics strategies, represents a pivotal step in shaping the future of intelligent, customer-centric financial ecosystems.

LLM-Powered Prescription Cart Intelligence: A Hybrid System for Real-Time Drug Interaction Detection in E-Commerce

Deepanjan Mukherjee

Read Abstract

The present online pharmacy market lacks real-time drug-drug interaction detection during the shopping experience. This paper presents a unique system to detect interactions directly in e-commerce pharmacy shopping carts, reducing the risk of adverse drug reactions that could lead to potential hospitalizations. The hybrid system combines the current rule-based checking using commercial databases (DrugBank, First DataBank) with Large Language Models (LLMs) to improve contextual analysis through Retrieval-Augmented Generation (RAG). A three-layer design comprising of interaction detection, LLM enhancement, and user experience layers is proposed, to achieve under 500ms response times through microservices architecture and multi-tier caching, while generating user-friendly natural language explanations. A confidence scoring mechanism flags uncertain outputs for further pharmacy review and intervention to ensure user safety. The system also addresses critical limitations of current similar tools requiring use of separate interaction checkers by providing seamless cart-level integration. The proposed evaluation methodology targets >90% sensitivity for major interactions and >80% specificity to minimize pharmacist fatigue due to false positives.
