Many modern computer vision and machine learning applications rely on solving difficult optimization problems that involve non-differentiable objective functions and constraints. The alternating direction method of multipliers (ADMM) is a widely used approach to solve such problems. Relaxed ADMM is a generalization of ADMM that often achieves better performance, but its efficiency depends strongly...
In order to consider the uncertainty of DG and loads, the interval number is used to describe the uncertainty of the wind speed and loads. The optimal selection and configuration of distributed generators model is established for distribution systems. The largest investment income for independent power producer of DG is taken as the objective function, and interval power flow is introduced to determine...
<?Pub Dtl?>In this paper, it is shown that analyzing the subsynchronous oscillation (SSO) damping effectiveness of an induction machine damping unit (IMDU) only based on its torque-slip characteristic curve is not adequate. A method to directly calculate the electrical damping of an IMDU according to its parameters, which is fast and accurate, is developed. This direct calculation method makes...
This article studies a paper cutting platform in a comprehensive approach to folk art, folklore, communication, computer and information science focusing on paper-cut in Hebei China. The main content includes: 1) the data collecting and recording of the scattered Chinese folk paper-cut work in Hebei, 2) the digitization, optimization, compression, classification, icon and pattern extraction, vectorization...
The combined FEM-BEM method used to get the frequency response of the vibration and the noise radiation was applied on a gear-box which was the main noise source on the ZH1130 single engine diesel. Based on the prototype using the method, various optimization designs on the component were carried out. And the final design was got through the topology optimization method. The final design was manufactured...
