An economical and effective method to measure displacement is to integrate the acceleration signal. Because of the zero drift in the acceleration sensor, there will be a trend term in the process of acceleration secondary integration, which will cause some errors in displacement measurement. In this paper, several methods of acceleration signal processing with zero drift are given, and the advantages and disadvantages of these methods as well as the applicable occasions are analysed, which have important reference value for selecting reasonable methods in dealing with engineering problems.
The COVID-19 outbreak has not only brought tremendous challenges but also significantly influenced all aspects of society. Because of its influence, it is essential to reconsider the educational advantages of studying in another country. The study covered education abroad, which has taken on a new form in the wake of the COVID-19 outbreak due to prior research. Additionally, several contemporary concerns have surfaced as a result of this paper. To begin, the change in pedagogical approaches has brought about a decline in the overall quality of the educational system. The third issue is that recurring tuition costs are assessed, and the second is that the school day has been shortened, leading to questions about students' academic credentials. To solve these problems, four different strategies can be implemented: improving teaching methods and elevating educational standards; preserving the legal and educational system and ensuring academic standards; standardizing tuition fees and eliminating the practice of selling academic credentials; and, lastly, combating opportunism and eliminating the environment of studying abroad.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
