Surface Tension vs Interfacial Tension. Both surface tension and interfacial tension are effects based on liquids. Both these effects take place due to the unbalanced intermolecular forces between the liquid or solutions molecules.
Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps ensure the process operates efficiently, producing more specification-conforming product with less waste (rework or scrap).
Calculating Process Capability. When process data fails to produce a normal distribution, special indices are required to calculate process capability. This course teaches Black Belt candidates the indices for non-normal process capability, and discusses how to transform non-normal data for use in standard statistical tests.
