Abstract

The precise measurements of the magnetic field are essential for particle accelerators, and the harmonic coil measurement system is especially suitable for the multipole field because of its unique advantages. The accurate placement of magnets is essential for accurate magnetic field measurements. The current positioning technique employed for harmonic coil measurement is inefficient due to its labor-intensive and time-consuming nature. The aim of this study is to automate the positioning of the quadrupole magnet. Therefore, a close-range photogrammetry system is utilized to monitor the position of the magnet due to its non-contact feature, and an electrically driven Stewart platform is utilized to manipulate the magnet. Meanwhile, a control system has been developed to regulate the automatic positioning. The system is capable of receiving measurements from the close-range photogrammetry system in order to ascertain the displacements of the magnet from its current position to the target. Subsequently, it can transmit commands to Stewart platform to regulate its movement. The experiments indicate that the efficiency of the quadrupole magnet positioning has increased significantly by at least 5 times, and the final positioning accuracy was verified by the laser tracker. The study also addresses the potential application of this technology in high radiation environments that are otherwise inaccessible. [ABSTRACT FROM AUTHOR]

Abstract

During the period of COVID-19, the number of residents infected in urban communities continued to rise, implying that most of the current building layouts can't effectively resist the spread of infectious diseases, and the outbreak of COVID-19 has led to the need of changes for the current building environment. Therefore, the epidemic prevention should be considered in the residential building design, and the health design of residential community should be carried out from the perspective of epidemic prevention. In order to improve the ability of epidemic prevention of residential buildings and deal with the sudden pandemic and influenza in the post-epidemic era, a Healthy Assessment System for Residential Building Epidemic Prevention (HASRBEP) was developed according to the epidemic impact on residential buildings, the design and measures of epidemic prevention for residential buildings and the Chinese Assessment standard for healthy building (T/ASC 02–2016). Both entropy weight method and expert scoring method were used to determine the specific weight of the index. The HASRBEP includes control item assessment, preliminary assessment and extension assessment. The newly developed HASRBEP was used to assess the residential buildings of the Yulongzhuang Building Community located in Quanzhou, Fujian Province, China. The results show that the HASRBEP can be used to guide the health and epidemic prevention design of residential buildings.
