This paper describes the power flow control of a triple active bridge (TAB) DC-DC converter for a DC power distribution system. The proposed phase shift control utilized in power distribution is based on varying the phase shift angle among three ports of the converter. First the simulation system is a prototype 200-V TAB converter with double loads for low-voltage DC power distribution systems using...
In this paper, the indirect method of finite element analysis was built for analyzing temperature and stress field of an H‐beam heating process via Ansys software. The convection and radioactive heat flux were calculated, respectively for the solutions of temperature field, the offspring of the Ansys software. The solutions of temperature field were the initial conditions for stress field calculation...
The required time of aircraft turnaround support activity directly affects the aircraft combat effectiveness. Aiming at the problem that the shortest time of support activity is hard to realize under the limited aircraft support resources conditions, the time optimization algorithm based on Branch and Cut Method (BCM) of the aircraft turnaround support activity is given in this paper. The purpose...
The physical-layer network coding (PNC) has become a hot research topic, since it can potentially reduce the transmission time slots and increase the channel capacity. However, current studies are mainly concentrated on three nodes (two users and one relay) network. This paper considers a specific multiuser network that includes M (M>2) users with one relay, and illustrates the transmission scheme...
It is necessary for a server oriented to the Internet of Things (IOT) applications to provide countless connections with efficient and reliable service. Meanwhile the communication layer should try to lower the overhead. Therefore a highly efficient design for a socket server with buffer pool and a thread pool for concurrent request on the IOT platform is presented. This reduces the system overhead...
