The current teaching methods and the progress of education mode, to a large extent by computers and network technology push While the development of network multimedia technology, promote the development of the education theory and education system Along with the country to the attention of the digital campus construction, everyday teaching activities and teaching methods and teaching means increasingly update, in the field of education plays an extremely important role. In the course of daily music teaching, how to use multimedia technology to realize the visualization of music teaching; How to improve teaching quality and teaching efficiency; How to optimize and integrate the existing teaching resources, strengthen the management of daily business and teaching resources; How to establish effective teaching mode is the problem to be solved in the process of music teaching.

As an advanced detection technology in the industrial field, electrical capacitance tomography (ECT) can better reconstruct the material distribution state in the measured area by selecting the appropriate algorithm. In order to improve the reconstruction quality, this paper devises a novel objective function to model the ECT image reconstruction problem, in which L 1 -norm is deployed as data fidelity with the focus on weakening the influence of capacitance outliers on the reconstruction quality, L P regularization reinforces the sparseness of the phantom objects, and L 1 regularization applies to model deviation variables to increase the robustness of the system. Based on the fast-iterative shrinkage thresholding technique and the soft thresholding method as sub-solvers, the split Bregman iterative method is designed as an effective solver for the proposed objective function. Numerical simulation and experimental validate that the proposed algorithm has excellent imaging ability compared with other imaging algorithms, which provides a good choice for the practical application of ECT in the future.

With the rapid development of computer technology, the application of computer has penetrated into various fields, and the application of computer technology in art design has gradually increased. In order to improve the efficiency and overall level of art design, a computer-aided design system of art graphics was designed and developed based on a comprehensive analysis of the needs of art design. This article introduces the construction and implementation of computeraided design system for art graphics, including system architecture, functional structure, database design, and system function implementation. The function and performance analysis of the system shows that the computer-aided design system based on art graphics can shorten the development cycle of art design works, improve the efficiency of art design work, and facilitate the simulation and inspection of art works. Based on the requirements of art graphic design, the development of computer art graphic aided design system will not only help to improve the efficiency of art design, but also further improve the level of art design. We will conduct in-depth exploration of the development of China and provide theoretical and technical support.
