Real-time data lakes, which aggregate and process both streaming and batch data, have emerged as key enablers of this capability. This paper explores the integration of Apache Flink, a powerful stream processing engine, and Apache Iceberg, an open table format, to build a high-performance real-time data lake. The combination of these technologies allows for seamless handling of both real-time and historical data, ensuring low-latency queries and efficient storage. We delve into the architectural design, key challenges, and optimizations required to implement a robust system capable of handling diverse workloads. Furthermore, the paper highlights best practices for managing schema evolution, optimizing data partitioning, and ensuring transactional consistency. The integration of Flink and Iceberg not only enhances data accessibility and reliability but also offers a scalable solution for organizations seeking to leverage real-time analytics. Our findings demonstrate the efficacy of this approach in improving data processing speed, accuracy, and overall system performance. In the era of big data, organizations increasingly rely on real-time analytics to gain timely insights and maintain competitive advantage. This paper presents a comprehensive approach to designing and implementing a high-performance real-time data lake using Apache Flink and Apache Iceberg. We explore how Flink, as a robust stream processing engine, can handle real-time data ingestion, processing, and analytics, while Iceberg provides an efficient and scalable data lake storage format. The integration of these technologies is examined to address key challenges such as data consistency, schema evolution, and system scalability. Through practical case studies and performance benchmarks, we demonstrate how this architecture supports low-latency querying, reliable data management, and seamless integration with existing data infrastructure. Our findings provide valuable insights into optimizing real-time data lakes for large-scale data operations and highlight best practices for leveraging Flink and Iceberg in a modern data ecosystem.

This study investigate the optimal conditions for variable SNR values and appropriate threshold values can be examined through concurrent analysis of Pf and Pm when employing energy detector techniques for spectrum sensing. As the proposed method demonstrates higher Pm and lower Pm at low SNR, it fulfills the EDSS optimality criteria for low SNR environments. Additionally, this approach enables threshold verification at high SNR values, and subsequent research could focus on primary user detection. Furthermore, diverse sensing techniques can be applied to contemporary wireless technologies. Additional investigation of various parameters utilizing different methodologies is strongly recommended to improve spectrum sensing outcomes in cognitive radio networks.

Counterfeit goods pose a significant threat to the product manufacturing industries, directly impacting sales and profits. To counteract this issue, blockchain technology is proposed as a means to prevent product counterfeiting across the supply chain. With blockchain, consumers no longer need to rely on trusted third parties to verify the source and authenticity of purchased goods. Blockchain technology ensures that data is tamper-resistant, as it employs a decentralized, distributed, and digital ledger that stores transactional records, known as blocks, across multiple networks. This immutable characteristic of blockchain ensures that no changes can be made to one block without altering subsequent blocks. In this paper, a counterfeit product detection system is proposed, leveraging barcode readers in conjunction with a Blockchain-Based Management (BCBM) system. The system stores product details and unique product codes in a blockchain database and verifies the authenticity of the product by matching the customer-provided code with the entries in the blockchain. If a match is found, the consumer is notified of the product’s authenticity; otherwise, the system collects information on the origin of the counterfeit product to identify the manufacturer.

The goal of the Clinical Laboratory Management Application is to improve the accuracy and efficiency of laboratory work in healthcare environments. Every clinical laboratory needs to maintain test records, and generating reports in the correct format can be quite complex. Additionally, managing the financial activities associated with patient tests poses challenges for lab technicians. This application addresses these issues, offering a user-friendly solution that simplifies record-keeping and report generation. This application will aim at creating advancement in manual keeping of clinical data records. This application streamlines processes such as sample tracking, result reporting, inventory management, and compliance with regulatory standards. Clinical Laboratory Management`s features, which include user-friendly interfaces, automated workflows, and strong security measures, not only support quality improvement initiatives but also increase operational efficiency, which ultimately improves patient outcomes and makes the healthcare delivery system more efficient.
