Distributed data stream management systems (DDSMS) are usually composed of upper layer relational query systems (RQS) and lower layer stream processing systems (SPS). When users submit new queries to RQS, a query planner needs to be converted into a directed acyclic graph (DAG) consisting of tasks which are running on SPS. Based on different query requests and data stream properties, SPS need to configure...
Storm is a popular real-time processing system. However, our earlier experiment shows that the fixed configuration of Storm would lead to either significant resource waste or limited processing throughput. In this demonstration, we present AdaStorm, a system to dynamically adjust the Storm configuration according to current data stream properties. AdaStorm is designed to minimize the resource usage...
It becomes necessary to utilize electromagnetic/ electromechanical hybrid simulator to modern large HVAC and DC power system, where multiple HVDC links feed into concentrated load areas. In this paper, a practical real-time hybrid simulator is proposed. The simulator makes RTDS and external transient program running on a computer link together effectively and smoothly. The entire interface schemes...
