Hypermedia systems are information tools that allow flexible navigation through several topics. This approach is being increasingly used in educational environments. However, these systems have disadvantages: if the hyperspace is big enough (and usually it is), the users become overwhelmed by the amount of paths and topics available, and get lost in the hyperspace losing even the benefits of li...

We propose a method to determine single hyperspace vectors (product strings of noisebits) by classical means with the same effectiveness as the results using time shifted noise-based logic. A system of binary linear equations based on the amplitudes of the hyperspace vector and the reference noise-bits is set up and solved after enough independent information is collected. The resulting error p...

We study the problem of when the hyperspace CL(A) of a subspace A of a space X is canonically representable as a subspace of the hyperspace CL(X), where both CL(A) and CL(X) are endowed with one of the following hypertopologies: Fell, Wijsman, d-proximal, Hausdorff, locally finite, proximal

With the advent of hypertext it has become widely accepted that the departure from the so-called " linear " structure of paper increases the likelihood of readers or users becoming lost. In this paper we will discuss this aspect of hypertext in terms of its validity, the lessons to be learned from the psychology of navigation and the applicability of the navigation metaphor to the hypertext dom...

Hyperspace theory has its beginnings in the early years of XX century with the work of Felix Hausdorff (1868-1942) and Leopold Vietoris (1891-2002). Given a topological space X, the hyperspace 2X of all nonempty closed subsets of X is equipped with the Vietoris topology, also called the exponential topology, see [37, p. 160] or the finite topology, see [48, p. 153], introduced in 1922 by Vietor...
