FREE AUGMENTED LD-SYSTEMS

Free augmented LD-systems

Define an augmented LD-system, or ALD-system, to be a set equipped with two binary operations, one satisfying the left self-distributivity law x ∗ (y ∗ z) = (x ∗ y) ∗ (x ∗ z) and the other satisfying the mixed laws (x ◦ y) ∗ z = x ∗ (y ∗ z) and x ∗ (y ◦ z) = (x ∗ y) ◦ (x ∗ z). We solve the word problem of the ALD laws, and prove that every element in the parenthesized braid group B• of [2, 3, 5...

Calibration-Free Augmented Reality

Camera calibration and the acquisition of Euclidean 3D measurements have so far been considered necessary requirements for overlaying three-dimensional graphical objects with live video. In this article we describe a new approach to video-based augmented reality that avoids both requirements: it does not use any metric information about the calibration parameters of the camera or the 3D locatio...

An augmented context free grammar

This paper presents an augmented context free grammar which describes important features of the surface structure and the semantics of discourse in a formal way, integrating new as well as previously existing insights into a unified framework. The structures covered include lists, narratives, subordinating and coordinating rhetorical relations, topic chains and interruptions. The paper discusse...

Artificial-intelligence-augmented systems.

Today, AI is an established and widely recognized field in its own right, that traversed the research and teaching circles of universities and eventually entered the production centers of industries. The field of AI is considered to have been born at a 2-month workshop held in Dartmouth College, Hanover, NH, USA, in the summer of 1956. The workshop was organized by Marvin Minsky and John McCart...
