Schnyder Woods and Orthogonal Surfaces
In this paper we study connections between planar graphs, Schnyder woods, and orthogonal surfaces. Schnyder woods and the face counting approach have important applications in gra...

Analysis of Inconsistency in Graph-Based Viewpoints: A Category-Theoretic Approach
Eliciting the requirements for a proposed system typically involves different stakeholders with different expertise, responsibilities, and perspectives. Viewpoints-based approache...

A Topological Approach to Recognition
We propose a new approach to the notion of recognition, which departs from the classical definitions by three specific features. First, it does not rely on automata. Secondly, it...

Linkability estimation between subjects and message contents using formal concepts
In this paper, we examine how conclusions about linkability threats can be drawn by analyzing message contents and subject knowledge in arbitrary communication systems. At first, ...

A Gestural Interface to Free-Form Deformation
We present a gesture-based user interface to Free-Form Deformation (FFD). Traditional interfaces for FFD require the manipulation of individual points in a lattice of control vert...
