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.
Nomophobia is the irrational fear of being without your mobile phone or being unable to use your phone for some reason, such as the absence of a signal or running out of minutes or battery power. A phobia is by definition an irrational fear. In the case of nomophobia, the events that the user fears are not terribly unlikely, so that part of it isn't irrational. What is irrational is the degree of discomfort the users feel at the thought of being, in effect, separated from their smartphones.
