An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
Nomos or Nomoi may refer to: from the Greek term for law (Î½ÏÎ¼Î¿Ï, nÃ³mos; pl. Î½ÏÎ¼Î¿Î¹, nÃ³moi). It is the origin of the suffix -onomy, as in astronomy, economy, or taxonomy.
The term nomological is derived from Greek and means lawful, so the nomological network can be thought of as the lawful network.. The nomological network was Cronbach and Meehl's view of construct validity. That is, in order to provide evidence that your measure has construct validity, Cronbach and Meehl argued that you had to develop a nomological network for your measure.
