Prediction of essential proteins which are crucial to an organism survival is important for disease analysis and drug design, as well the understanding cellular life. The majority prediction methods infer possibility be by using network topology. However, these limited complementation available protein-protein interaction (PPI) data depend on accuracy. To overcome limitation, some computational have been proposed while seldom them solve this problem taking consideration protein domains. In...

Mobile computers and devices may operate in a variety of environments with different security schemes. In this paper, we present mobile agent based model.

After discussing possible threats, is explained at length analysis also given way collaboration requirements, mobility requirements execution requirements.

The grid-forming inverters have received much attention due to the great voltage and frequency support ability. However, a lot of transient instability phenomena been reported inverters. In order improve stability inverters, an asymmetric virtual impedance is proposed simulate reluctance torque synchronous generator increase power transfer Furthermore, design considered from dimensions d axis q respectively, effect on shown perspectives increasing margin providing larger deceleration area....

The intangible cultural heritage of China contains many different forms performing arts, which oral performance is an important branch. "Hua'er" the most popular folk sung in Hui ethnic area Ningxia. Based on technology virtual reality (VR) and gesture recognition, our work proposes three design methods: interactive narrative, metaphorical elements embodied cognition, applied to VR performance, "Flower Youth". can provide audience with a more immersed experience that contributes transmission...

In this paper, a kind of virtual synchronous generator control algorithm is proposed that can accurately simulate the external characteristic generator. This based on park mathematical model considers motor salient pole effect and influence damper windings. Using two-step Adams method to solve for current motor's port, converter controlled track so output status values have same port characteristics with actual motor. Simulation results verify in many typical working conditions such as...

Inverters controlled in virtual synchronous generator(VSG) method is able to operate both grid-connected mode and islanding mode. Due this characteristic, paper put forwards a low voltage ride-through(LVRT) strategy which based on VSG control. If the grid sags, can limit output current amplitude meanwhile inject reactive power grid. Once drop time exceeds maximum ride-through time, would smoothly switch continues carry loads independently. The proposed achieves control algorithm unity...

A grid-forming VSC control strategy when connected to a weak grid considering the ability of symmetrical and asymmetrical faults ride-through is studied in this paper.
