Throughout history, humanity has encountered numerous crises and pandemics. Yet, our resilience, innovation, and capacity for creative problem-solving have consistently guided us through these challenges. Presently, the world is confronted with the COVID-19 pandemic, stemming from a novel coronavirus originating in Wuhan, China, and swiftly spreading across the globe, infecting millions. However, in times of adversity, rigorous measures and inventive approaches become imperative. This study is dedicated to analyzing COVID-19 data using advanced visualization techniques to chart and juxtapose the outbreak's progression across various continents and territories, including the USA, China, India, Italy, and Taiwan. Employing metrics such as total confirmed cases, fatalities, and recoveries for each region, this analysis harnesses the power of data visualization to facilitate comparisons. Ultimately, this research endeavors to furnish a comprehensive insight into the global impact of COVID-19 through the integration of Data Visualization and Machine Learning methodologies.

Medication nonadherence is a tremendous health problem, especially in resource limited settings, where there are no explicit automation and real time tracking of medication with traditional methods of medication management. However, these methods are based on patient self-reporting, using which they can miss doses or make errors. An IoT enabled, smart medical dispenser, which automates prescription retrieval, medication dispensed and adherence monitoring is introduced in this paper. Real time prescription verification is used for dispensed medication to each patient via RFID technology. As such, a load cell sensor is incorporated to verify whether or not each tablet is dispensed to reduce the chances that doses could be missed. This system is in contrast to traditional methods that lead to real time location that reduces the chance of errors in dosing. The system has a cloud-based dashboard, which enables the remote monitoring of patient adherence by healthcare professionals or caregivers. This is especially beneficial for the underserved community and government hospital, where access to medical supervision is not as frequent as you would expect. It integrates IoT, RF ID authentication and cloud-based adherence tracking which helps in reducing human error, improve patient safety. Ultimately, it is a scalable and low-cost solution that will be equally simple to implement in both home and clinical settings making it an effective tool for improving medication adherence and resulting health outcomes in resource limited environments.

AUTOMATED TOLL COLLECTION SYSTEM WITH ZIGBEE COMMUNICATION

Toll collection systems have evolved over time, with the introduction of cloud computing. A proposed system combines contactless payment methods, cloud-based services, and real-time data processing to improve toll collection. The system's central control unit is a Raspberry Pi board, which connects parts and the cloud. The toll booth uses an RFID scanner to recognize RFID-tagged vehicles, and the sensor module captures real-time data from cars passing through stations. The system also features an LCD screen for user and toll booth manager information. Vehicle information and collected data are securely transmitted and stored in a centralized database for processing via cloud integration. This allows for real-time monitoring of toll transactions, automatic toll charge calculation, and seamless payment gateway integration. Contactless payment technology, such as electronic wallets and smartphone apps, enhances user comfort and facilitates a secure toll collection process. The system reports and analyzes data via cloud services, enhancing transportation planning, optimizing toll pricing strategies, and understanding traffic patterns.
