Design and Manufacture of Light String Electric Piano

Abstract

The laser harp is expensive, not suitable for public use, a light string electric piano has designed by using laser tube and SCM. The feasibility of the scheme is verified in a series of experiments, at the same time,the product has a large market in promoting the teaching instrument and toy design with very broad prospects through the market survey.

Digital resurrection of historical figures: A case study on Mary Sibley through customized ChatGPT

“…After obtaining a representative sample of sedan wheel hubs and a Kansei word, quantitative Ⅰ theory needs to be applied to match the two for the study. The main method is to construct a mathematical model between the independent and dependent variables through multiple linear regression [26,27,29]. This study conducted data analysis in four main stages.…”

“…Chen et al [26] proposed the main steps of constructing the mapping between perceptual imagery and product design elements based on Quantitative Theory I: firstly, get the perceptual imagery evaluation value of a representative sample of products through design research (dependent variable); secondly, extract the product design elements (independent variables); and thirdly, take the product design items as the items, Secondly, the product design elements (independent variables) are extracted; thirdly, a mathematical model is built by taking the product design items as items, the product design elements as categories, and the perceptual imagery evaluation values as dependent variables; then the mathematical model is solved by Matlab or SPSS software; finally, the data results are analyzed, in which the category scores indicate the influence of the product design elements on the perceptual vocabulary, the complex correlation coefficients are used to measure the model's precision, and the partial correlation coefficients represent the contribution value of the design items on perceptual vocabulary. Wang et al investigated the effects of different combinations of electric scooter components on user emotions based on quantitative-I theory analysis methods and constructed a prediction model for the mapping between the appearance of electric scooters and users' perceptual needs [27]. Chen et al applied quantitative class I to analyze the influence weights of perceptual factors, constructed a quantitative class I statistical table, and selected the perceptual factors in the table that have a greater influence on the shape of tea pets as a consideration for style adjustment before design [26].…”
