In recent years, many electrical fires have occurred due to complex causes. Therefore, products are required to make with scientific design considering electrical, thermal, mechanical and environmental influences. Disasters can cause losses of life and property with fall in confidence of countries and companies. And demands for safe product have been increased by reason of recent deregulation followed by limitless competition. It is necessary to design safe product in order to improve corporate image and strengthen international competitive power. This paper addresses electrical fire case of air conditioner. The use of air conditioner have recently increased as a result of global warming. The aim of this study is to provide safety design and fire prevention measures of air conditioner through cause analysis and reappearance experiments.
Service mobility has become a new issue in the area of service convergence with the advent of versatile mobile devices. Hence, we propose an open service framework with support for service mobility that executes contents and applications in a dynamic environment. For the framework, the concept and role of a device and its application for a service are redefined into the new concepts of device, execution engine, and service. Mechanisms for device profiling, user preference learning, and profile-based service recommendation are designed to enable device-capability-aware service recommendation functionality. A prototype system integrates functionalities with proprietary protocol and a content transcoder to support multiple device platforms. The prototype shows the capability of the framework in service mobility support and its advancement into an open international application platform.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
