The sublexical structure of a sign language

Lucinda Ferreira Brito, Rémi Langevin (1994)

Mathématiques et Sciences Humaines

Similarity:

Analyzing and transcribing a sign language is a difficult task since the mode of expression - hand movements in a space located close to the body, complemented by attitudes and facial expressions - is a priori less sequential than speech. Our work aims to complete numerous previous attempts and uses in particular Stokoe’s system. Analysing the movement of a frame attached to the hand as the movement of a point in R 3 × S O ( 3 ) we manage to discretize in a natural way the most frequent gestures of...

Properties of space motions with two straight trajectories

Marie Kargerová (1990)

Aplikace matematiky

Similarity:

The paper is devoted to Euclidean space motions with two straight trajectories on two given skew straight lines. It describes all motions from this class which have one more planar trajectory in a plane not parallel to the given lines. In the conclusion it given conditions under which such motions have further planar trajectories in planes not parallel to the given skew straight lines.
