In this paper, we implement the ski jump visualization tool using the OpenGL graphics library. Among the evaluation elements of jump, the distance of jump is most important. Also, the distance of jump depends on Lift-to-Drag Ratio. In the previous studies, the visualization too according to the consequential changing of variety factors is insufficient. This study provides an easy style flying posture visualization tool to the user who using Lift-to-Drag Ratio. Furthermore, there is to implement an international standard jumping hill by virtue of entered five main data. The results of this study can be applied with reference data for better ski jump.
Recently, Elevator industry is pursuing new challenges to the model of the IT convergence. The core of the convergence technologies may be the effective control and maintenance of the machine. However, because current elevator management model provides each specific model for his elevator, the management models have a variety of heterogeneous configuration so that it makes management companies to manage the elevators with many overhead. In this paper, we propose the integration framework for the various elevator models. We use proposed system based on the Android framework that is rapidly expanding technology in the embedded environment, and we propose design approach for the integration of variety of lift devices so that it provide a more efficient and stable service environment. In this way, we could integrate various device models of an elevator for the management and maintenance effectively and quickly.
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.
