Achieving Circularity through Novel Product-Service Systems in the Mining Industry: An Opportunity for Circularity

Constructive Truth and Circularity

We propose a constructive interpretation of truth which resolves the standard semantic paradoxes. 1. Heuristic concepts In intuitionism the law of excluded middle (LEM) is not accepted because the assignment of truth values to sentences is seen as a kind of open-ended process. Although the validity of any purported proof is supposed to be decidable, the truth value of a given sentence may not b...

Discrete Circularity Measure

A new circularity measure for discrete objects is introduced and an algorithm to compute this measure is presented. This measure equals 0 for all discrete circles and is strictly positive for all discrete objects which are not discrete circles.

Circularity of Planar Graphs

A circular cover of a graph G is a cover {X0, · · · , Xn−1} of the topological space G by closed connected subsets, indexed over Zn, with the following properties: Each element in the cover contains a vertex of G, each vertex of G is contained in at most two elements of the cover, and Xa ∩ Xb 6= ∅ if and only if b − a ∈ {−1, 0, 1}. The circularity of G is the largest integer n for which there i...

Voodoo and circularity errors

We briefly describe the circularity/non-independence problem, and our perception of the impact the ensuing discussion has had on fMRI research.
