In general, impeller, difruser, and casing have an important role in a turbo-compressor, because the dynamic energy of the impeller transformed into the pressure energy in the diffuser and casing. The performance characteristics of the difruser are complicated with different geometric shapes. To im...
In this work, application of the fieldshaper has been proposed to concentrate the magnetic pressure at the desired location for effective wire crimping. Numerical analysis was carried out using LS-DYNA TM on three different types of field-shaper namely single-step, double-step and tapered. In ...
On the other hand, quantitative data, which includes numerical values, is suitable for statistical data analysis and can be represented using various graphs. Discrete data, which has whole numbers, and continuous data, which has fractional values, are subtypes of quantitative data. Knowing the type...
1. Types of Data Visualization Charts: Column Chart Column charts use vertical columns to show numerical comparisons between categories, and the number of columns should not be too large (the labels of the axis may appear incomplete if there are too many columns). ...
Also read “What is Data Analytics” to grasp the fundamentals of extracting value from data. 2.Quantitative Data Quantitative data is a type of data that can be expressed in numerical values, making it countable and including statistical data analysis. These kinds of data are also known as N...
Nonparametric statistics are easy to use but do not offer the pinpoint accuracy of other statistical models. This type of analysis is often best suited when considering the order of something, where even if the numerical data changes, the results will likely stay the same. ...
相关系数种类(Types of correlation coefficients) Types of correlation coefficients (I) Pearson product difference correlation (K. Pearson product-moment correlation; R) 1. X variables: isometry, ratio variables (continuous variables) 2. Y variables: isometry, ratio variables (continuous variables) 3. ...
Ordinal datarefers to categorical data that has a defined order, and can therefore support storage as numerical values. For example, we can define values ofbig,medium, andsmallas ordinal data because we can numerically rank thembig > medium > small. By contrast, the valuesapple,orange,...
