Input-series-output-parallel (ISOP) isolated bidirectional DC/DC converter (IBDC) become a preferred scheme connecting high-voltage and low-voltage bus in DC distribution network. Input-voltage-sharing (IVS) among modules is essential to realize the stable operation of ISOP system. Nowadays, with large-scale access distributed energy sources loads grids, fluctuations voltage connected load freq...

Reliability and efficiency become more important in data transmission application in wireless sensor networks (WSNs). Many studies have been proposed to improve the network reliability and energy efficiency, but most of them were complicated to implement in energy-limited WSNs. This paper is dedicated to research a high performance protocol named NCCM-DC, which is a N etwork C oding based C lus...

Software defined network is a new computer network architecture who separates controller and data layer in network devices such as switches and routers. By the emerge of software defined networks, a class of location problems, called controller placement problem, has attracted much more research attention. The task in the problem is to simultaneously find optimal number and location of controll...

Although there are many perceived benefits to Network Address Translation (NAT), its primary benefit of "amplifying" available address space is not needed in IPv6. In addition to NAT’s many serious disadvantages, there is a perception that other benefits exist, such as a variety of management and security attributes that could be useful for an Internet Protocol site. IPv6 was designed with the ...

DC distribution network consists of distributed generation, energy storage, load and AC network, With the rapid development increasing proportion load, operation mode is more flexible. Different from traditional has a single mode, while can operate in both parallel island mode. Therefore, control method suitable for different modes urgently needed. In this paper, about loop closing opening prop...

Most of intelligent control in movement control involves fuzzy logic and neural network systems. In this research, a neural network is used to detect and diagnose the faults that may occur in a DC motor system during robot operations. The DC motor system is constructed using the SIMULINK toolbox. This system provides the normal and faulty data that has been used for training purpose in the neur...

In this paper, using artificial neural network ANN for tracking of maximum power point is discussed. Error back propagation method is used in order to train neural network. Neural network has advantages of fast and precisely tracking of maximum power point. In this method neural network is used to specify the reference voltage of maximum power point under different atmospheric conditions. By pr...

We study the transport properties of a superconducting Nb film with a square lattice of artificial pinning centers (APCs) as a function of dc current, at a temperature close to the superconducting transition temperature of the film. We find that, at low dc currents, the differential resistance of the film shows the standard matching field anomaly, that is, the differential resistance has a loca...
