It is generally required to be able to extract the individual frequency components which are present in a signal – sometimes because the original signal generating the vibration contains many components (as is the case for periodic, random or transient types of excitation), and … These results from observational studies almost never replicate in randomized studies. The concept of spurious correlation was first introduced by Karl Pearson in 1897, 1 where he describes how one can obtain a significant value for a coefficient of correlation when the two variables in reality are absolutely uncorrelated. Note the low-level spurious signals (in red) between 1.0 and 10 MHz offset. Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment (e.g., a treatment group versus a control group) using randomization, such as by a chance procedure (e.g., flipping a coin) or a random number generator. Much progress has been made in the development of supported metal catalysts for CO 2 hydrogenation, such as Cu/ZnO/Al 2 O 3 (2–10), Cu/ZrO 2 (2–5, 11–13), and Pd/ZnO (2–5, 14, 15).Among these, the Cu/ZnO/Al 2 O 3 catalyst was the most efficient and has been extensively studied.
