The collaborative nature of industrial wireless network system (IWNS) brings several advantages over traditional wired industrial monitoring and controlsystems, while commercial products and real-world deployments of IWNS are faced with harsh reliability and predictability issues, which are mainly attributed to the unreliable nature of individual wireless link. In this paper, we research Multi-Hop Multi-Channel wireless communication link (WCL). We model Multi-Hop Multi-Channel WCL at first, and then we present a optimal transmission scheduling policy based on join allocation of slots and channels problem. Following that, we relax the problem into a Subprime solution which is suitable for engineering application. At last, we developed testbed and achieved expectation result that Multi Hop Multi-Channel employing our transmission scheduling policy improved reliability obviously.

In this paper, clutter suppression and target detection in clutter edge is discussed. Firstly the statistical model of the clutter edge is established, based on which maximum likelihood estimation for the transition range bin of the clutter edge is derived. Simulations illustrate that by carefully choosing the secondary samples based on the estimation result of the transition range bin, the signal to inference plus noise ratio (SINR) can be improved significantly.
Because the structure and function of a high-rise building is complex and the density of occupants in it is high, fire safety is still a worldwide difficult problem. Safety and timely evacuation is an important issue ...

This paper established a failure criterion of frozen soil based on fracture mechanics considering various defects and destruction mechanism of frozen soil. The criterion fits for frozen soil under small scale yielding conditions or brittle fracture. It indicates that the failure criterion is valid by applying to the actual anti-frozen research of hydraulic structures destruction. It provides a new idea for the research on the anti-frozen damage to hydraulic structures in seasonal frozen soil area.

This paper deals with advanced control strategies for the Hybrid HVAC-HVDC interconnection of large power systems. The simulations use of a simplified model of the European ENTSO-E and the Russian IPS/UPS systems developed within the scope of the ICOEUR project (Intelligent Coordination of Operation and Emergency control of EU and Russian Power Grids). The plausibility of ENTSO-E - IPS/UPS interconnection using a hybrid HVAC-HVDC interface is discussed and the benefits of a newly developed control algorithm for advanced control of hybrid interface are presented. The simulation results demonstrate that the centralized control of the power flows on HVDC lines allows the performance and the security of the hybrid interconnections and the interconnected power systems to be greatly enhanced.
