If Xt is a wide-sense stationary process then the mean Î¼ and the variance Ï2 are time-independent, and further the autocorrelation depends only on the lag between t and s: the correlation depends only on the time-distance between the pair of values but not on their position in time.
Febreze is classified as an air freshner, created by Proctor & Gamble. It reports to work by trapping odor molecules in a donut-shaped chemical. The first thing that is really important to understand: the product does not remove odor molecules and it doesn't clean the item it comes into contact with.
Since finding non-toxic alternatives to use in my home is so important to me, I knew that I had to create an alternative to FebrezeÂ® spray. My homemade FebrezeÂ® spray is just a few ingredients and itâs totally effective at eliminating all kinds of odors; from pet urine and cigarette smoke to fish and mildew. And of course the best part is that itâs completely non-toxic!
