3 Visualization of Conway Polyhedron Notation

Authors: Hidetoshi Nonaka

Abstract:

This paper presents an interactive modeling system of polyhedra using the isomorphic graphs. Especially, Conway polyhedron notation is implemented. The notation can be observed as interactive animation.

Keywords: Visualization, Conway polyhedron notation, Polyhedral graph

2 Modeling of Kepler-Poinsot Solid Using Isomorphic Polyhedral Graph

Authors: Hidetoshi Nonaka

Abstract:

This paper presents an interactive modeling system of uniform polyhedra using the isomorphic graphs. Especially, Kepler-Poinsot solids are formed by modifications of dodecahedron and icosahedron.

Keywords: Shape modeling, Graph Drawing, Kepler-Poinsot solid, Polyhedralgraph

1 Sensing Pressure for Authentication System Using Keystroke Dynamics

Authors: Hidetoshi Nonaka, Masahito Kurihara

Abstract:

In this paper, an authentication system using keystroke dynamics is presented. We introduced pressure sensing for the improvement of the accuracy of measurement and durability against intrusion using key-logger, and so on, however additional instrument is needed. As the result, it has been found that the pressure sensing is also effective for estimation of real moment of keystroke.

Keywords: Biometric authentication, Time-Frequency Analysis, Pressure Sensing, keystroke dynamics
