LEAP
LEAP, the Linux-Equipped Astronauts Project, is a project to port to Linux those applications that the astronauts use on their laptops, so that each astronaut has a choice of operating systems. We know that several of the astronauts already use Linux at home, and would appreciate being able to use […]

Low-Discrepancy Sampling This is the PhD work of Jonathan Quinn about creating low-discrepancy sampling sequwnces of surfaces utilising space-filling curves. This has been applied to point-based rendering, remeshing and robotic painting (in collaboration with Jonathan Corney and Finlay McPherson). Jonathan’s supervisors are Frank Langbein and Ralph Martin.

Monster Overview
Our approach is based on two ideas: (1) decomposing a model into suitable sub-parts simplifies finding regularities, which are less ambiguous compared to analysing the model as one part; and (2) detecting approximate symmetries and related regularities reveals a likely design intent description, but requires careful handling of tolerances to […]

Astarte is intended to become a general object oriented development and user environment specifically aimed for scientific applications. Many scientific projects require complex software. Usually software developed for a certain research project cannot easily be applied or used by other projects. An expandable and adaptable environment especially designed for scientific […]

DeLia intends to address those problems as a universal packaging, configuration and administration system. Instead of setting exact requirements for the configuration of a system the intention is to provide a flexible approach to the configuration within a fixed, but general framework of options. However, at this stage it does […]
