In this paper, we define a new measure to compute spatio-temporal similarity between two trajectories of moving objects on road networks, which is known as spatio-temporal distance (STDist). In addition, we propose a new spatio-temporal similar trajectory search algorithm to retrieve similar trajectories based on the spatio-temporal distance, a combination(More)
As a result of aging population, the incidence of pelvic insufficiency fracture has been increasing. Pain-related immobility caused by pelvic insufficiency fractures may result in a serious dependency and high mortality with preexisting comorbidities. We present two cases of pelvic insufficiency fracture in elderly patients which had good clinical outcome(More)
A cluster management tool is needed for monitoring and managing cluster systems or cluster DBMSs. The cluster system management tools have been extensively studied by a couple of research groups, whereas the design of cluster DBMS management tools is still in the early stages. In this paper, we design and implement a high-availability cluster management(More)
