Australians spend a lot of time cooking outdoors. Public parks have barbeques for anyone to use, sausage sizzles are a ubiquitous way to fundraise money for local community groups, and practically every household has some form of cooking appliance in the backyard or on the balcony. Open fires, wok burners, barbeques, tandoors, pizza ovens, satay grills, rotisseries, seafood boilers, smoke houses and pit ovens are used across the country.
I’ve been characterising a high performance gyroscope at work recently by measuring the Allan variance of its rate output. From the Allan variance plot, it’s possible to visualise and calculate the various sources of noise that cause error, including quantisation noise, angular random walk, bias instability and rate random walk. Each of these noise sources is caused by a different physical process and can be differentiated by its colour. What is noise colour, you ask?
I’ve been building the foundations for this blog over the past few weeks and it seems fitting that the very first post should cover some of my experiences.
