From Classroom Experiments to Computer Code

Forno, Arianna Dal; Merlone, Ugo - In: Journal of Artificial Societies and Social Simulation 7 (2004) 3, pp. 2-2

A carefully designed experimental procedure may be an invaluable source for gathering empirical data and a key to grasping the heterogeneity of human behavior, which is of the utmost importance when modeling artificial agents. This paper proposes an alternative way of inferring models of...

Wind energy conversion with a variable-ratio gearbox: design and analysis

Hall, John F.; Mecklenborg, Christine A.; Chen, Dongmei; … - In: Renewable Energy 36 (2011) 3, pp. 1075-1080

Variable-speed wind turbines are able to adapt to low wind speeds and therefore have greater efficiency than fixed-speed turbines during partial-load operation. Unfortunately, the high cost and low reliability of the electronics that enable variation in speed have discouraged this mode of...
