Self-rated health (SRH) is considered a relevant and important predictor for major health outcomes in the older population. SRH status may interact with certain factors and change over a person's lifetime. In this study, we sought to characterize profiles of older people over time by constructing prototypical trajectories of the variable of interest, namely(More)
Recently, Cloud Computing is getting considerable attentions not only as the technology trend but also the new business model. Virtualization plays an extremely important role in Cloud Computing. Server virtualization has been achieved using virtualization hypervisor software such as VMware, Xen, and KVM,etc. Virtual Machines (VMs) created by hypervisors(More)
BACKGROUND To investigate changes over time in risk factors for the development of Activities of Daily Living (ADL) disabilities in older adults with arthritis. METHODS The data were obtained from the Longitudinal Survey of Health and Living Status of the Elderly in Taiwan (1989-1999). The major analytic cohort comprised 977 older adults (458 men and 519(More)
With the explosive growth of Internet, various applications are developed. Their common feature is the desire for higher network bandwidth than before. Network backbone has been upgraded from 155 Mbps with ATM technology to Gigabit Ethernet or 10 Gigabit Ethernet to meet this trend. Besides, some next-generation e-science applications such as video(More)
This study used community-based cohort data to explore the trajectory stability (tracking coefficient or stability coefficient) and its influencing factors on the longitudinal age-related change in physical performance among older populations. An integrated statistical method with generalized estimating equations was applied to study trajectory stability.(More)
Recently, Software Defined Network (SDN) technology has become widely used to take advantage of its features, including capabilities for optimization, flexibility, and customization. Many companies and organizations are applying this technology to build SDN networks for testbeds or production networks to address their requirements for optimization and(More)
Internet has played an important part in the success of information technologies. With growing and changing demands, there are many limitations faced by current Internet. A number of network test beds are created for solving a set of specific problems in Internet. Traditionally, these test beds are lacking of large scale network and flexibility. Therefore,(More)
