In this paper we present a novel framework based on multi-feature extraction for anomaly detection in video surveillance which global anomaly and local anomaly are detected separately. To detect global anomaly, we define kinetic energy Ek and compute the first derivative of Ek and then derive a global anomaly score of each test frame. As for local anomaly detection, three kinds of local anomaly are...
To study the transverse flow pressure and flow pressure torque generated by non-uniform flow that the ship encounters when it passes the entrance of breakwater in the process of driving away from the port, a ship model sailing at the end of breakwater and a digital basin were established by utilizing computational fluid dynamics. In this way, numerical calculation was conducted for the tide field...
For the purpose of engineering development for failure insert testing, a HiL model for automatic transmission was established and key boards of dSPACE system which contributed testing were set up. Aimed to simulate solenoid and sensor failure insert testing, the testing theory and method were introduced. Testing results showed that failure insert testing method can be used for solenoid and sensor...
In order to achieve the ability of primary frequency regulation better, the boiler-turbine coordinated control system for the large capacity unit has become an important research in thermal control field, using the mechanism mathematical model for reference, utilizing the method of pressure node, the dynamic simulation mathematic model of the coordinated control system for supercritical units is given,...
We developed a 3D parallel full band Monte Carlo simulator for semiconductor devices. This enables us to simulate 3D devices on high performance multiprocessor machines. By utilizing the JASMIN software package, parallel execution issues such as processors communication, grid partitioning and load balancing are handled easily and efficiently. The 3D MC simulator is validated by comparing its results...
