The connection of business processes along the value chain and the integration of the production system with business process are two cornerstones of Industry 4.0. The Industry 4.0 Demonstration Production Line (DPL) located at Shenyang Institute of Automation (Shenyang) is a prototype smart factory that implements end-to-end customized production. It is also a testbed for intelligent manufacturing...
A bipolar dc microgrid features three voltage levels and is capable of transmitting power more efficiently than a unipolar system. This paper proposes a droop control to achieve load sharing and voltage balancing in such a microgrid system. Droop control is adopted to ensure that autonomous sharing of load power can be realized without communication. Moreover, the positive and negative pole voltages...
High voltage transmission line fault location algorithm without synchronization, which does not require sampling synchronization, reduces cost and has a higher practical engineering value. But the algorithm still needs to be improved in the false root identification of ranging equation, this paper makes a further research on this issue. Firstly, the false root problem of fault location algorithm without...
We consider a channel with N parallel sub-bands. There is a single user that can access exactly k channels, while maintaining some minimum rate at each accessed channel. The transmission takes place in the presence of a jammer which can access at most m channels. We cast the problem as an extensive-form game and derive the optimal power allocation strategies for both the user and the jammer. We present...

In order to analyze a five-degree-of-freedom (DOF) manipulator for special applications, this paper establishes its kinematics model firstly, and then analyzes its workspace and characteristics, and gets its inverse kinematics solution. Finally, its advantages and disadvantages are presented. On the basis of kinematics analysis, combining with the typical operating cases, we point out the existing...
Many historical structures now need to be retrofitted to meet the requirements of fast developing cities. To ensure the safety of a historical masonry building during its retrofitting, natural frequency of the structure was measured through ambient vibrating tests. A simulation model was established and used to evaluate the equivalent elastic modulus of the masonry based on the test results. The properties...
In the previous work, we proposed a generic method to analyze and reduce the bias in localization algorithms. The proposed method combines the Taylor series and Jacobian matrices to determine the bias and leads to an easily calculated analytical bias expression. However all the previous works focus on the terrestrial localization applications. In this paper we extend the method to underwater localization...
This paper analysis the sections of a Low temperature Co-fired Ceramic (LTCC) helical inductor, presents a new circuit model of LTCC helical inductor. Simulation of presented circuit model matches the result of full wave electromagnetic simulation until 9GHz.
This paper presents a new mathematical model of a solar module. Solar module temperature, solar radiation and its effect on series resistance are taken into account in the model. The experimental data of the solar module under natural environment condition have been obtained to determine the model parameters. Then, the developed model is used to simulate energy yield of the solar module. This energy...
