A Categorical Manifesto - Goguen (1991)   (20 citations)  (Correct)

....argued that morphisms are more important than objects, because they reveal what the structure really is. Moreover, the category concept can be defined using only morphisms. Perhaps the bias of modern Western languages and cultures towards objects rather than relationships accounts for this (see [50, 64] for some related discussion) By way of notation, we use ; for composition, and 1 A for the identity morphism at an object A. Now some examples: 1.1 Sets. If we take sets to be objects, then their morphisms are clearly going to be functions. A set morphism, however, is not just a set of ordered ....

Navigational Behaviors Based on Optical Flow Using the Ground .. - Haider, Herwig (1994)   (Correct)

....its physical extension since it it not the camera which might collide with an obstacle but any corner of the vehicle. 4 Discussion Visuomotor control guideline The way in which an organism perceives its world is tailored by the ecological niche to which it adapted through its history of evolution [26]. Vision must be described in terms of the specific affordances [4] offered by the environment and the repertoire of behaviors an animal performs in order to reach certain goals. The robot and its behaviors should be designed specifically for certain tasks in the environment. It is misleading to ....

Tossing Algebraic Flowers down the Great Divide - Goguen (1999)   (2 citations)  (Correct)

....the components that: i) through their interactions and transformations continuously regenerate the network of processes that produced them; and (ii) constitute it as a concrete unity in the space in which they exist by specifying the topological domain of its realization as such a network. See [2, 167, 143, 145] for more on this area, and see [171, 112] for some possibly ill advised attempts to formalize this notion; also cf. footnote 4. Sorry for the confusing prose in this quote. The relevance of this to software engineering is discussed in [42] Anyone familiar with large software projects knows that ....
