Comparative cognition of number and space: the case of geometry and of the mental number line
Evidence is discussed about the use of geometric information for spatial orientation and the association between space and numbers in non-human animals.

Impact of Fjord Geometry on Grounding Line Stability
Recent and past retreat of marine-terminating glaciers are broadly consistent with observed ocean warming, yet responses vary significantly within regions experiencing similar ocean conditions. We assess how fjord geometry modulates glacier response to a

Many methods are proposed to deal with the type synthesis of parallel kinematic mechanisms(PKMs), but most of them are less intuitive to some extent. Thus, to propose a concise and intuitive type synthesis method for engineering application is a very ...

Covariant Space-Time Line Elements in the Friedmann–Lemaitre–Robertson–Walker Geometry
Most quantum gravity theories quantize space-time on the order of Planck length (ℓp ). Some of these theories, such as loop quantum gravity (LQG), predict that this discreetness could be manifested through Lorentz invariance violations (LIV) over ...

Integral geometry of pairs of hyperplanes or lines
AbstractCrofton’s formula of integral geometry evaluates the total motion invariant measure of the set of k-dimensional planes having nonempty intersection with a given convex body. This note deals with motion invariant measures on sets of pairs of hyperplanes or lines meeting a convex body. Particularly simple results are obtained if, and only if, the

On-Line Reconstruction of CAD Geometry [PDF]
In reverse engineering and computer-aided design (CAD) applications point cloud data is usually manually scanned, reconstructed, and post-processed in separated steps. When point cloud data resulting from a scanning process do not satisfy certain necessary reconstruction requirements, one must perform scanning again to enable proper reconstruction.

Multicolored lines in a finite geometry
AbstractLet t>1, let P1,…,Pt be pairwise disjoint nonvoid subsets of a finite set P, and let L be a collection of subsets of P called lines. We say that (P1,…,Pt;L) is a colored incidence structure if (i) each line meets at least two blocks Pi and Pj, (ii) for arbitrary distinct xϵPi and yϵPj the pair {x, y} is a subset of exactly one line if i≠j and ...
