A templated System-Call Interface for OO/MPStuBS ,Christian Dietrich

We use OOStuBS/MPStuBS in our operating system course. In the first part of our two part lecture, we have no isolation, but still want to provide a "system-call interface" that differentiates between application and kernel space.

Testing Three-Valued Vectors for Compatibility ,Christian Dietrich

For a colleagues project, we had the problem to compare three-valued vectors for compatibility. The corresponding values are either set or undefined. An undefined value is compatible to everything; a set value is compatible to the same value.
