A Comprehensive Survey on Optimizing Storage Models, Data Layouts, and System Catalogs
Abstract: This survey compares four papers that propose solutions for optimizing the storage model, data layout, and system catalogs in data management systems for hybrid workloads, which consist of both analytical and transactional queries. These solutions include a main memory hybrid storage engine that separates the storage of analytical and transactional data and uses a sophisticated query optimizer, a hands-free adaptive store that adjusts the storage layout based on access patterns, …

General Health Check-up, Health Care Model using CNN and Internet-of-Medical Things
Abstract: Many people may believe that undergoing a comprehensive medical check-up is unnecessary when they feel perfectly healthy. However, this perception is mistaken. Regular health check-ups are essential to maintain overall well-being and to detect potential health issues early, enabling proactive steps to prevent them from worsening. Such check-ups are valuable for both individuals in good health and those with existing medical conditions, as they provide insight into the progress of …

RDTP: Reliable Delay Time Protocol with Duty Cycle Optimization in 6LoWPAN-WBAN
Abstract: Medium access control (MAC) protocols based on the adaptive duty cycle and the IEEE 802.15.4 standard have recently been proposed to address the Quality of Service (QoS) requirements of wireless body area sensor networks. These QoS requirements include time-bound data transmission services, data rate, reliability, and energy consumption. Providing a comprehensive set of QoS is difficult with the present protocols, though. Furthermore, these protocols adjust duty cycle values by considering …
