Otto Cycle of Internal Combustion Engines, Gamma vs Compression Ratio, Adiabatic Processes - Physics

This physics video tutorial provides a basic introduction into the otto cycle of an internal combustion engine. The first step is an adiabatic process when the gas undergoes compression. As the volume decreases, the temperature of the gas increases and the pressure greatly increases favo

Abstract : Recall that normality is a elementary form of randomness: an infinite word is normal to a given alphabet if all blocks of symbols of the same length occur in the word with the same asymptotic frequency. We consider a notion of independence on pairs of infinite words formalising
