Abstract: A piston for an internal combustion engine and a method for producing a piston are disclosed. The piston includes an upper piston part and a lower piston part that together delimit a circumferential cooling channel for receiving a cooling medium both radially inside and radially outside.

Abstract: Data characterizing a quantifiable outcome for each of a plurality of game trials can be accessed. Each game trial can be associated with one of a plurality of players and a game. The game can be a digital game played on a computing platform. Using the accessed data, a first variance measure of the quantifiable outcome for all game trials associated with the plurality of players can be computed. For one or more of the plurality of players and using the accessed data, a second variance measure of the quantifiable outcome for the game trials associated with the one or more of the plurality of players can be computed. Based on at least the first variance measure and the second variance measure, a skill factor for the game can be computed. Data characterizing the skill factor can be provided.
