Authors: He Fengping 
Published: August 2021

Abstract
The switching on and switching off operation of some IOT devices is a complex physical, chemical and mechanical nonlinear transient process, which contains a lot of information. The information has distinction, stability and clear physical meaning. Due to the short time of transient process and the rapid change of waveform and characteristic parameters from time to time, it is difficult for traditional test instruments to capture the characteristics of voltage, current and power consumption in the transient process. Therefore, this paper develops a set of transient characteristic test system of IOT equipment by using the graphical programming software LabVIEW, which realizes the accurate measurement, automatic analysis and display of transient process waveform and characteristic parameters. Taking the operating coil of an electronic product as the test object, the transient characteristics in the whole process of on-off, closing process and breaking process are tested and verified by using the test system, which improves the efficiency of detection and analysis of the performance of IOT equipment.

Consider link bandwidth available and the node processing power of heterogeneity, the repair delay and repair traffic node of combinatorial optimization. Topology can be converted to Steiner tree model with constraints, and design the corresponding hybrid genetic algorithm to solve the approximate global optimal solution. Finally, a compromise between the two optimization objectives is achieved. Simulation results show that under the same MSR code size, the repair delay of this topology is only 60%-80% of that of the traditional tree topology and 30%-40% of that of the traditional star topology. While the repair traffic for this topology is 9% to 65% higher than for the traditional star topology, the repair traffic is only 40% to 55% higher than for the traditional tree topology.

Abstract
In this thesis, a real time singing scoring system based on virtual reality technology is proposed. When a user sings a song, the system will analyse and process the user’s audio, compare it with the standard audio, give the corresponding score and change the character animation in the scene in real time according to the score level. By giving the user a visually realistic experience, the system creates desensitisation, thus reducing the user’s fear of performing on stage and improving their ability to perform on stage.
