However, the storage subsystem has always been a prohibitive factor that slows down the pace of reaching even higher performance while maintaining good user experience. Despite today’s smartphones are equipped with larger-than-ever main memories, they...
A variety of applications (App) installed on mobile systems such as smartphones enrich our lives, but make it more difficult to the system management. For example, finding the specific Apps becomes more inconvenient due to more Apps installed on smartphones, and App response time could become longer because of the gap between more, larger Apps and limited memory capacity. Recent work has proposed...
For mobile devices, communication via cellular networks consumes more energy than via WiFi networks, and suffers an expensive limited data plan. On the other hand, as the coverage and the density of WiFI networks are smaller than those of the cellular networks, users cannot purely rely on WiFi to access the Internet.

This paper presents information on an autonomous fall detection and alerting system mainly consisting of a custom vest and a mobile smart phone. A 3-axial accelerator and gyroscope with a main board and Bluetooth are built into a custom vest worn by elderly. The vest can capture the data about the activities of daily living (ADLs) of elderly in real time. The data via Bluetooth is then sent to a mobile...
