Some simulation fun

Today is a day off, Liberation day. I was up to some scientific fun in the afternoon. It came in two kinds.

Science in question concerns the current in overheated transistor (http://yuli.weblog.tudelft.nl/2009/12/15/fully-overheated-sigle-electron-transist ) that we study with Matti Laakso. We have concentrated on current fluctuations and recently have found a regime where these fluctuations are really wild. The distribution of current values is of Patero type, and it so happends that the average current is parametrically bigger than its optimal value. This suggest that the time-line of these fluctuations must be rather amusing: most time current is low, but occasionally it gives a giganitic surge that drops quickly to the low level. The average current is determined by surges. I wanted to simulate stochastic dynamics giving rise to such a time-line.

Recently I fall in love with python programming language. Being invented by math student Guido van Rossum, it’s certainly a biggest contribution of the Netherlands to world culture for at least last thirty years. Too bad Guido could not find the job over here. I’ve made a draft simulator in python within an hour, and rather advanced and reliable one within another hour, and the prog text is still 48 lines ( six of them are blank). So I could see these miracluous surges, up to four orders of magnitude above the normal level.

I’ve thoroughly enjoyed.

Go Yuli! Kudos from a fellow Python afficionado …
