Access to Healthcare is significant especially to elderly people who are living independently. An Internet-based tele-healthcare system can decrease costs both in time and travel as for example, elderly people don't need to travel to the hospital for routine physical examinations. This research uses state-and-transition graph analysis to plan and design a tele-healthcare system. The state-and-transition graph makes the healthcare process clearer and ensures that correct care interventions are made at the right time. With the tele-healthcare system, elderly people can do physical examinations at home. The examination data are sent to the tele-healthcare server via the Internet and are analyzed and categorized into four alarm levels. The system then arranges correspondent care actions automatically. The system has been used by Care Centre of Elderly People in Taiwan.

The current study experimentally investigates the heat transfer augmentation on the novel axial corrugated heat exchanger tube in which the spring tape is introduced. Air (Pr = 0.707) is used as a working fluid. In order to augment the thermohydraulic performance, a corrugated tube with inserts is offered. The experimental study is further extended by varying the important parameters like spring ratio (y = 1.5, 2.0, 2.5) and Reynolds number (Re = 10 000–52 000). The angular pitch between the two neighboring corrugations and the angle of the corrugation is kept constant through the experiments at β = 1200 and α = 600 respectively, while two different corrugations heights (h) are analyzed. While increasing the corrugation height and decreasing the spring ratio, the impact of the swirling effect improves the thermal performance of the system. The maximum thermal performance is obtained when the corrugation height is h = 0.2 and spring ratio y = 1.5. Eventually, correlations for predicting friction factor (f) and Nusselt number (Nu) are developed.
