In this paper, we firstly study the partial least squares (PLS) and locally weighted project regression (LWPR) methods. As a result, we find out that both methods leave some space for improvement. Then we put forward a new method, called LWPR-MPLS, to improve the traditional statistics and their thresholds. Our method reduces the computation load significantly and therefore can deal with nonlinear...
Web social media has become one of the major channels for people to express their opinions, share their feelings and communicate with others. Public opinions often ebb and flow with time due to the occurrence of social events and mutual influence of people on certain topics.

The research object of this paper is negative control system in axial piston pump, which widely used in excavator. The control system changes the delivery of the pump by the complicated mechanism to realize the adjustment of the pump flow rate. This paper takes advantages of the AMESim and ADAMS to build the system hydraulic model and mechanical model separately, and lets them exchange data to complete...
