The ＂smartphone＂ availability has increased in both developed and developing counffies even among people in rural and remotes areas. Telebased services can be used for screening ophthalmic diseases and also monitoring patients with known diseases. Electronic ophthalmologic records of the patients including captured images by smartphones from anterior and posterior segments of the eye will be evaluated by ophthalmologists, and if patients require further evaluations, they will be referred to experts in the relevant field. Eye diseases such as cataract, glaucoma, age-related macular degeneration, diabetic retinopathy, and retinopathy of prematurity are the most common causes of blindness in many countries and beneficial use of teleophthalmology with smartphones will be a good way to achieve the aim of VISION 2020 all over the world. Numerous studies have shown that teleophthalmology is similar to the conventional eye care system in clinical outcomes and even provides more patient satisfaction as it saves time and cost, This review explains how teleophthalmology helps to improve patient outcomes through smartphones.展开更多

Different from the traditional event based control method, the new framework does not require every part of the system to be strictly event synchronized. Instead, it allows time referenced control components to be integrated into this framework, which makes it more convenient to develop Internet based control systems. Since there are two reference variables, time and event, in this architecture, how to coordinate these components with different references to keep the stability of the whole system is discussed in detail in this paper. To verify this new idea, an experiment was conducted to control the end effector of a PUMA robot tracking a continuous state trajectory given on-line by the remote operator. Ex-perimental results confirmed the stability of such systems being controlled through the Internet in real-time.展开更多

However, suita- ble transmissions of tele-protection services continues to be a challenging area in the electrical- supply sector since link stability as well as various performance tests suggest that link recurrence requirements still exhibit limitations when using Metroethernet networks in this context. At pre- sent, improvements have been achieved via proprietary protocols such as Mirrored Bits, which matches the performance of a tele-protection link transmission under normal operation conditions. However, this imposes commercial limitations on the Colombian electrical-supply sector since proprietary protocols hinder fair competition among manufacturers. This is the rationale behind conducting trials with precision time protocol as it is defined in IEEE 1588 standard. The main purpose is to validate whether, under real operation conditions, it is possible to substitute such tele-protection links via Metroethernet networks, yet considering a standard protocol that allows incorporating various pieces of equipment from different manufacturers into the system as well as providing common benefits derived from using this type of communication networks. The present work provides technical results obtained after conducting various simulated tele-trigger tests, including stress tests, where results-stability validation occurs through network-saturation simulations. These saturation conditions are achieved by incorporating additional traffic, which involves several switching events over link paths and permits validating tele-protection-response timing when specifically using IEEE 1588 precision time protocol. Based on the aforementioned reasons as well as on the resulting benefits, a series of laboratory tests have been defined in order to evaluate delay and availability on tele-protection services when transported over IP networks.展开更多

This study used TELES to simulate the earthquake scenario parameters, such as PGA distribution, casualty case, liquefaction potential index and the total number of occurring fires based on the Meinong fault seismic source. Finally, according to the most damaging areas of the simulation results, we propose to strengthen the important buildings and facilities such as the reservoir area, and the emergency responsive hospitals for a better seismic risk estimation and the earthquake disaster prevention and response. According to the simulation results analysis, we found the areas with the strongest magnitude were in Meinong Dist. in Kaohsiung city. Nevertheless, the areas suffering the serious disasters were in Tainan city. Due to the serious disasters occurring in Tainan city, it is crucial to discuss how to perform anti-earthquake practices in Tainan area and how to coordinate the support from different cities and counties.展开更多

The system consists of ECG recorders with network interface and the embedded web server, internet networks and computers, with the system operating on browser/server(B/S) mode. The ECG recorder was designed by ARM9 (S3C2410X) and embedded operating system (Linux). Once the ECG recorder has been connected to the internet network, medical experts can use the internet to access the server of the ECG recorder, monitor ECG signals, and diagnose patients by browsing the dynamic web pages in the embedded web server. The experimental results reveal that the designed system is stable, reliable, and suitable for the use in real-time ECG tele-monitoring for both family and community health care.展开更多
