Abstract. This paper introduces the constitution and working principle of a LabVIEW platform-based pressure detection system. Flexiforce transducer is engaged in the detection system for data acquisition of clothing pressure. Particularly, least square curve fitting algorithm principle and linear regression analysis technique are expounded in the system. Therefore, the proposed pressure detection system could analyze real-time data of pressure and conduct objective test dynamically. This scheme is not only suitable for the design of pressure detection system, but also has certain guiding significance for a wide range of sensor detection system design.
The rolling motion analysis of ships or other marine structures is of paramount importance. However, one of the thorniest issues in the analysis is the determination of roll damping. The main objective of this work is to apply the Partial Least-Squares regression into the Bass Energy Method and Roberts Method, which are used for the identification of non-linear roll damping parameters. When the number of sample points decreases due to limitations of the experimental conditions and other factors, the differences between the results obtained from Partial Least-Squares Regression and from traditional Least-Squares method demonstrate the applicability of the proposed method.
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.
