This yields a coalgebraically defined notion of observational indistinguishability, as well as an algebraically defined notion of reachability under computations.
It is shown that the frequency domain approach yields a tool to fast and easily design friction control in practice with high detection sensitivity and orthogonal tuning of the controller parameters, while providing a well defined notion of optimal performance.
So in spite of the distinct Kantian flavor of a term like "respect for persons" in the bioethics literature, usually all that remains of the Kantian understanding of autonomy in this field is a broadly defined notion of self-rule or individual choice that is equally compatible with a Millian notion of liberty and with what Kant would have deemed heteronomous springs of action.
In the 1970s and 80s a more defined notion of "gayness" was emerging and pubs, bars and clubs opened to cater for individual tastes, such as the dark, testosterone-fuelled Coleherne in Earl's Court, west London and the cathedral of disco, Heaven, in Charing Cross.
Anomalies or outliers are patterns in data that do not conform to a well defined notion of normal behavior [ 13].
This is not a very well defined notion since it depends on the imaginative abilities of individuals, mostly in normal health, who have never personally experienced moderate or severe health problems.
Our ultimate concern, therefore - especially in times of difficulty - becomes a narrowly and erroneously defined notion of public health and personal wellbeing, and our prayers are most zealously offered to the real god of our communal devotion: the almighty market.
This coincides with the algebraically defined notion of a context given above.
In terms of the defined notion of satisfaction, Tarski introduces the notion of a model of a sentence.
And in terms of the defined notion of model Tarski proposes his defined notion of logical consequence.
Let us give an example which will illustrate the role of the above defined notions.
