The load unbalance is one of inherent features of distribution systems which draws a negative sequence current from islanded synchronous generators. This leads to overheating of the stator and, in particular, the rotor core. In such a case, it is not possible to operate the generator at its associated rated power. Thus, implementing an inverter-based resource in parallel with the synchronous ge...

The current trend in Online Dispute Resolution focuses mostly on the development of technological tools that allow parties to solve conflicts through telecommunication means. However, this tendency leaves aside key issues, namely our concern with respect to context information that was previously available in traditional Alternative Dispute Resolution processes. The main weakness of this approa...

Testing TBM (Test Blanket Modules) is one of important engineering test objectives in ITER project. China is performing the TBM design and R&D based on Chinese development strategy of fusion DEMO. Helium-cooled test blanket module concept with ceramic breeder for testing on ITER will be one of the basic options in China. The current progress and status on design and R&D of CH HC-SB (Chinese Hel...

By minimizing the total potential energy function and deploying the virtual work principle, a higher-order stiffness matrix is achieved. This new tangent stiffness matrix is used to solve the frame with geometric nonlinear behavior. Since authors’ formulation takes into account the higher-order terms of the strain vector, the convergence speed of the solution process will increase. In fac...

This paper investigates the dynamic frame skipping strategy in video transcoding. To speed up the operation, a video transcoder usually reuses the decoded motion vectors to reencode the video sequences at a lower bit-rate. When frame skipping is allowed in a transcoder, those motion vectors can not be reused because the motion vectors of the current frame is no longer estimated from the immedia...

The three-phase four-leg inverter can produce balanced voltages even with unbalanced loads, yet its controller design is quite complicated. Based on the analysis on time domain equations, a decoupled sequence control strategy for the three-phase four-leg inverter in a low-voltage network is proposed. A negative sequence controller and a zero sequence controller are added to the control strategy...
