A Dirac all-electron basis and spin-orbit coupled projector implementation of the Projector Augmented Wave Method for atomic systems
The Projector Augmented Wave Method (PAW) [1] provides accurate numerical approximations to the exact eigenfunctions and eigenvalues of the Kohn-Sham equations for large-scale ab-initio electronic structure calculations of molecules and solids, for which exact calculations are impractical. …

Mindful navigation with guiding light : design considerations for projector based indoor navigation assistance system
People can easily become mindless in their decision-making and become disengaged from their surroundings when their actions depend on information and guidance from an assistive technology. Research has shown how automated navigation assistance systems lead users to be disengaged from the space …

Head Tracked Multi User Autostereoscopic 3D Display Investigations
… controlled by a multi-user head tracker. A laser projector was used in the first two versions and, although this projector operated on holographic principles in order to obtain the spot pattern required to produce the exit pupils, it should be noted that images seen by the viewers are not produced …
