This paper examines the development of adaptive hypermedia systems and proposes adaptive characteristics for third generation adaptive hypermedia systems. First generation adaptive hypermedia systems predated the World-Wide Web (WWW) and were primarily single user adaptive hypermedia systems. Second generation systems have exploited the distributed nature and ease of authoring of the WWW to dev...

We present new dispersion and hydrogen bond corrections to the PM6 method, PM6-D3H+, and its implementation in the GAMESS program. The method combines the DFT-D3 dispersion correction by Grimme et al. with a modified version of the H+ hydrogen bond correction by Korth. Overall, the interaction energy of PM6-D3H+ is very similar to PM6-DH2 and PM6-DH+, with RMSD and MAD values within 0.02 kcal/m...
