Nowadays, manufacturing enterprises provide custo-mers not only product but the integration solution of product and service i.e. Product Service Systems(PSS). So far, many scholars have studied the PSS, but few apply Information and Communication Technology(ICT) to PSS in the era of internet. We propose to apply Smart Interconnection Technology(SIT) to PSS in the present study and formulate a model and analyze this model in detail. As a tool, Smart Interconnection Technology will benefit manufacturer, service provider and customer. It can improve responsiveness of firms to service and aid to feedback to firms. There are some problems as well as benefits. Pros and Cons are discussed in detail with applying SIT to PSS. Finally, we conduct an application of applying SIT to PSS. In the future, more information technologies should be used in PSS.

In order to make the sprayer boom follow the ground undulation during the processing of work, we designed a controller based on electro-hydraulic servo system to keep the boom balance. As for the time variant of the parameters and highly nonlinear in the electro-hydraulic servo system, the fuzzy-PID control method has been designed. The position output can be controlled on a predicted track to fulfilled the standard of fast and accuracy via fuzzy-PID method. The establishment of the fuzzy-PID control system?realized the control of the nonlinear uncertain parameters in the electro-hydraulic servo system. After the simulation and verification, we compared with the traditional fuzzy logic method. The results indicated that the controller designed in the paper has a great ability to track and also has a favourable control results to the uncertain and external disturb of the system.

From the perspective of operational logic, machine learning essentially uses the way of function, transforms the problem of machine learning into a function problem, and then implements machine learning by solving the objective function. The most important tool in solving the objective function is the optimization algorithm. In order to speed up the training process, it is necessary to design a parallel and distributed optimization algorithm in the context of big data. In recent years, many researchers have carried out extensive research on this issue, and some research results have been widely applied to the practice of machine learning.

In view of the problems existing in the existing wireless charging technology, this paper focused on the anti-offset performance of the charging area and system. Based on the principle of electromagnetics, the current density formula which can generate the uniform axial magnetic field strength was calculated, and the current density of the coil surface was combined, A new coil structure and a primary transmitting coil design method capable of realizing large uniform magnetic field distribution were proposed. The transmitting coil was systematically modeled by the COMSOL5.3 RF module and its axial spatial magnetic field strength and uniformity were simulated and analyzed, and multiple coil stitching superposition methods were further determined. The multi-dimensional visual electromagnetic measuring device was used to scan the axial magnetic field intensity of the primary transmitting coil surface, and compared with the simulation data, it was proved that the magnetic field distribution of the large primary transmitting coil formed after the splicing and superposition met the uniformity requirement.

Combining 3D virtual scene rendering with forest sub-compartment boundary editing, a forest sub-compartment boundary editing method in the 3D virtual scene is proposed. First of all, the boundary nodes were calculated according to the sub-compartment vector boundary in the 2D, and the boundary nodes were represented by entities in the 3D scene. Secondly, the node entities that need to be edited were picked up by using the mouse, and then interactive editing operations could be done such as moving and building. Lastly, the sub-compartment boundary nodes sorting algorithms for the 3D visual editing such as moving, cutting and merging of the boundary were proposed. The sub-compartment 3D boundary was redrawn according to the order of reordering entities. Taking the 2D vector data and terrain data of the specific sub-compartment as an example, the 3D visualization method of editing the sub-compartment boundary in forestry was verified based on the MOGRE rendering engine. The results show that this method can restore the real 3D existence form of the sub-compartment, reflect its 3D spatial structure characteristics, and directly implement the interactive editing operations and simulation results of 3D visual moving, cutting and merging for any sub-compartment boundary. This method can be directly applied to forest resources investigation, planning to improve the management ability.

Conventional Doppler warping (DW) method has good suppression effect for space-air based bistatic radar (SABBR) non-stationary clutter. But if radar geometrical configuration relations are unknown and range ambiguity exists, conventional DW method cannot be used. Aiming at range ambiguity clutter suppression problem for SABBR, a non-stationary clutter suppression method is put forward based on the ideas of improved DW method and reconstructing clutter covariance matrix (IDW+RCCM). Firstly, clutter covariance matrix of specified range ring is estimated through improved DW method. Then, power spectrum of the range ring is calculated as the amplitude value, and the clutter data and covariance matrix of the ambiguous range rings are reconstructed. Finally, the reconstructed data is used to achieve space-time adaptive processing for the range ambiguity clutter. Simulation results demonstrate the effectiveness of the proposed method.

With regard to the reliability of weapons after long-term storage including torpedoes, mines and missiles, this paper analyzes the practical dilemma that it is difficult to accurately determine the storage life of equipment at present, and points out that the storage life of components is crucial to the storage life of equipment. For this reason, a method is proposed to estimate the storage life distribution parameters of exponential component and then accurately evaluate the storage effect by utilizing the test results during the actual storage period. As revealed in the example design and numerous results of simulation verification, this proposed estimation method brings satisfying results, and overcomes the shortcoming of conventional storage test in its demand for a large number of samples, so it is of very high value for practical application.

Accurate and reasonable evaluation of hearing aid speech performance is especially important for hearing-impaired patients. In this paper, an objective evaluation algorithm for speech quality based on MARS (Multivariate adaptive regression spline) is proposed. In the algorithm, several basic features of speech signals are extracted, and MARS is used to select the key features that have great influence on speech quality. Then the optimal objective prediction model is built up to map the distortion measure of the characteristic parameter onto the subjective evaluation scores, which is substituted by PESQ. Finally, experimental verification shows that the correlation between the objective evaluation by the algorithm and the subjective evaluation scores is high, which is 0.978 and 0.9333 for training samples and test samples respectively.
