Research on collaborative filtering based on user interest in the higher vocational e-commerce website development
Authors: Gong Songjie 
Published: August 2021

Abstract
E-commerce Recommender Systems suggest useful and interesting products to customers in order to increase user satisfaction and online conversion rates. They typically exploit explicit or implicit user feedback such as ratings, buying records or clickstream data and apply statistical methods to derive recommendations. Collaborative filtering is one of the most widely used approaches in recommender systems. However, the traditional collaborative filtering methods compute users’ similarities in the dimension of products, and they do not take the influence of neighbor users into consideration when computing such similarities. This paper focuses on explicitly formulated user requirements as the sole type of user feedback. The new collaborative filtering method based on user interests’ transmission. This method computes customers’ similarities in the dimension of interests, and takes the interests transmission between different customers into reflection. This method not only can cope with cold start problem and data sparse problem, but also have prediction precision.

Optimization and Implementation of H.264 Encoder Based on DSP Platform
Authors: Yikui He 
Published: August 2021

Abstract
Aiming at the problem of low precision and long running time of traditional H.264 encoder algorithm, this paper proposes two optimization methods. One is to propose a method suitable for DSP to carry the reference frame, which can reduce the waiting time of DSP operation unit. By using DMA to read the data stored in the external access device in advance, all the data involved in the operation are stored in the memory of DSP chip. This improves the operation efficiency of DSP. Second, the macroblock based loop filtering makes the access times of DSP external memory minimum, and enhances the DSP’s ability of processing data. The test results show that the average decoding speed of the decoder is increased by 60% by the two optimization methods. The test system can decode CIF image at 526 MHz, and the speed can reach 30 frames per second.

Authors: Liu Jinnan , Cheng Shouguo 
Published: August 2021

Abstract
Double-slit nozzles are widely used in meltblown equipment. During the production process, two streams of high speed, high temperature hot air are ejected from two slits on both sides of the spinneret and converge to stretch and refine the polymer melt extruded from the spinneret. If we know the changes of airflow temperature and velocity in the flow field, we can simulate the fiber stretching and refinement process and predict the fiber properties to understand the fiber stretching mechanism, so as to guide the optimization design of meltblown process and improve the product quality and cost saving. In this thesis, a new meltblown die nozzle flow field model is developed based on the existing meltblown double-slot nozzle structure, which was improved from the theoretical model of meltblown double-slot nozzle developed by Ting Chen et al. In this thesis, the calculation area is determined and divided into meshes, and the Reynolds stress model is selected to simulate the flow field numerically, and the velocity and temperature distribution of the flow field along the axis of the spinneret is obtained.

Published: August 2021

Abstract
In view of the shortcomings of structured networks that it is difficult to manage complex shapes and unstructured networks cannot calculate the boundary layer viscous flow, an implicit algorithm based on mixed network points is proposed to solve the problem of successful calculation and high viscosity. Comparing absolute values is a difficult NP problem. It is caused by the interval problem and has a wide range of applications in many practical problems, such as: situation problems, semi-monitored and unprotected classification problems, and bag feasibility problems. When solving linear programming, double matrix strategy, quadratic programming and other problems, they must be converted into linear complementarity problems for processing, and linear complementarity problems can be summarized as absolute value equations. This article mainly introduces the smoothing Newton method of absolute value equation and the conjugate gradient algorithm of absolute value equation. This paper uses a hybrid network to analyze the algorithm and convergence of the absolute value equation, and establishes a potential mathematical model. The model is solved by the smoothing Newton method of the absolute value equation and the conjugate gradient algorithm of the absolute value equation, and the algorithm and convergence analysis results of the absolute value equation based on the hybrid network are evaluated, and the model is revised using historical data to improve The algorithm of the absolute value equation and the accuracy of the assessment of convergence analysis results. The experimental results in this paper show that the smoothing Newton method of the absolute value equation and the conjugate gradient algorithm of the absolute value equation increase the efficiency of the algorithm and convergence analysis of the absolute value equation by 23%, and reduce the false alarm rate and the false alarm rate. Finally, by comparing the experimental data analysis of the management strategy of sports services and the analysis of the reconstruction of sports services, the system illustrates the influence of artificial intelligence on the analysis of sports services’ management strategies.
