Integrating Content Management with Digital Rights Management
This white paper, published in May 2003, explores the task of effectively managing digital content while incorporating and protecting the digital rights associated with the content. The authors begin by defining a content management system as it is discussed in their paper and outline the key components and capabilities of such a system. After touching on the foundations of digital rights, the paper then argues for the adoption of a "Rights Expression Language" to integrate digital rights inform

Manipula math with Java : Hyppocrates' lunar
This applet leads students through a proof of how the area of two lunar sections is equal to the area of a triangle inscribed in a semicircle. The illustration uses color-coded sections and gives students hints to help find the theorem. The proof uses the Pythagorean theorem to establish the relationship between the lunar sections and the triangle. A separate sequence of diagrams shows the outline of the proof to simplify it.

4.6 Conclusion to Section 4
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
