Efficient problem-solving in any physical domain requires two main capabilities: the ability to ignore detail by reasoning at different levels of resolutio n (abstraction), and the ability to ignore irrelevant information by incorporatin g constraints and assumptions (simplification).

Qualitative Place Vocabularies for Mechanisms in Configuration Space. Jan ; B Faltings; Faltings, B. Qualitative Place Vocabularies for Mechanisms in Configuration Space. Configuration space is the appropriate basis for the place vocabulary because connectivity is central to kinematic state.

Faltings developed an elegant characterization of such places and algorithms for computing them (Faltings,). Instead of developing a single, massive high-dimensionality vocabulary, his algorithms created place.

construction of place vocabularies. Place vocabularies consist of places, contiguous regions of space where some important property (e.g., in contact with a gear, inside a well) is constant.

For exam­ ple, the kinematic topology of a pair of gears is one or several doubly connected regions, whose shape in configuration space indicates the rela­. Mechanism concepts and their kinematic behavi- from the configuration space to describe the oural characteristics are described and stored in a mechanism operating modes [ and an approach to computerised library using qualitative configuration generate place vocabulary from the configuration spaces accompanied by additional information such.

The place vocabulary is created from this information, and qualitative motion can be envisioned in terms of changes in state between these contact configurations. For example, the turning of a ratchet involves state transitions from contact between one gear tooth and the pawl, to a later state of contact with another gear tooth.

Then it divides the configuration space qualitatively (For example, CLOCK system uses "place Vocabulary" to represents the qualitative configuration space, [Forbus et a1,87, Forbus et, a1,91]) and envisions the qualitative behavior of the machine on the qualitative.

"This book presents the configuration space method. This paper presents a discussion of interview location in the context of nursing research with particular emphasis on the concepts of space and place. It draws on six research projects that were conducted between and in Canada, and is informed by key texts on the concepts of space and place.

He explains that “a place is the order (of whatever kind) in accord with which elements are distributed in relationships of coexistence”; a place is thus “an instantaneous configuration.

A significant amount of qualitative research takes place in the field. Yet the notion of analysing the place and material objects that contribute to the interactions and in situ behaviour of the participants is often overlooked.

This article shows. of the way people move, mostly along a line; (b) convex space where users see each other and in which interactions take place; (c) the visibility filed (isovist), which has a different shape depending on where the observer is located.

In a rectangular open field, the configuration space can be parametrized by the animal's position, indicated by the coordinates x and y, and by its head direction ϕ.

The total configuration space is then given by s = (x,y,ϕ) ∈ [0,L x] × [0,L y] × [0,2π[. L x and L y denote the size of the room in x- and y-direction, respectively. Language features, such as writing style and vocabulary, are the second important dimension of qualitative text complexity to consider.

Consequently, conformational sampling can be localized into key regions in configuration space, characterized by sub-ensembles. A multiscale approach deals with the process of coarse graining to reduce the number of dynamical variables in order to accurately describe a system within the most relevant sub-ensembles.

It seems to me that a good place to start would be the transition from the second to third density, then to investigate in detail the evolution of third-density entities of Earth, paying particular attention to the mechanisms which help or hinder that evolution.
