in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...

We show that light propagation in a group of degenerate modes of a multi-mode optical fiber in the presence of random mode coupling is described by a multi-component Manakov equation, thereby making multi-mode fibers the first reported physical system that admits true multi-component soliton solutions. The nonlinearity coefficient appearing in the equation is expressed rigorously in terms of th...

Transportation demand prediction is of great importance to urban governance and has become an essential function in many online applications. While efforts have been made for regional transportation prediction, predicting the diversified different communities (e.g., aged, juveniles) remains unexplored problem. However, this task challenging because joint influence spatio-temporal correlation am...

In the pilot provinces of China’s electricity spot market, power generation companies usually adopt separate bidding mode, which leads to a low willingness demand-side response and poor flexibility in interaction mechanism between supply demand. Based on analysis demand day-ahead market with participation sales companies, this paper abstracted game process “power grid-sales company-users” tripa...

This paper proposes the grid synchronization method of inverter using a quasi Proportional+Multi Resonant (P+MR) control-based voltage controller a stationary reference frame. The inverter supplies a non-linear load under the islanded mode. In islanded mode, the inverter is defined as a voltage source to supply the full local load demand without a connection to the grid. On the other hand, if t...
