Talking about the Application of Computer Reverse Engineering Concept in Sculpture Practice
Authors: Yu Xiaobo 
Published: February 2021

AbstractIn the field of modern sculpture manufacturing, the process of processing and designing complex sculptures is very complicated. Moreover, if technicians want to replicate complex sculptures, traditional sculpture methods will not work. In order to better analyze the sculptural methods of forming sculptures and the methods to replicate them, scholars have proposed the integration of computer reverse engineering concepts. In the actual sculpture practice, reverse engineering technology can make up for the shortcomings of positive design. With perfect reverse engineering technology, technicians can use computers to reconstruct complex sculptures and improve models. It is for this reason that scholars have invested a lot of time and energy on the basis of the combination of reverse engineering and sculpture practice.

Authors: Shi Xiaogang , Wang Tian 
Published: February 2021

Abstract
According to architectural thinking and related theoretical research, in the process of the self-manufacturing cycle of the whole life of a prefabricated building, there are many contracts involved in each construction phase and step. During this period, the amount of information generated by prefabricated buildings is also the most[1]. However, these are not headaches. Unfortunately, the excessive amount of information has caused various unprepared problems in the choice of sharing channels. The difficulty of information sharing hinders the implementation and management of prefabricated buildings to a certain extent. At present, under the guidance of the core of BIM technology supported by computer technology, scholars have conducted in-depth research on how to choose the way to share prefabricated building information. Hope this article can help related scholars find some ideas.

Design of Simulated Magnetic Gun
Authors: Huang Jian 
Published: February 2021

Abstract
STM32F103 single-chip microcomputer is used as the control unit of the simulated electromagnetic squint. The single-chip microcomputer is used to control the function of launching shell and steering gear angle, and the steering gear is used to control the launching angle and direction of the electromagnetic squint. In the design of electromagnetic gun, coaxial coil gun is used as the main part, and two batteries are used as the energy supply device. Then the electromagnetic relay connected with the single-chip microcontroller controls the cycle charging. Firstly, 12V DC power is input into the circuit by the DC stabilized voltage power supply. After the current enters into the circuit, it is divided into two branches. One branch flows through the boosting circuit of electromagnetic relay to charge the thyristor capacitor. With the switch off, the instantaneous discharge of the capacitor generates an inverter magnetic field in the coil, which pushes the metal projectile out at a high speed. What the electromagnetic relay does is to boost the voltage. What the thyristor capacitor needs is high voltage current charging. Another branch supplies 5V DC power to the steering gear through the step-down electromagnetic relay to support the rotation of the steering gear. The system obtains the target position through openmv, and STM32 uses PWM wave to control the rotation angle and direction of the steering gear.
