The international independent ranking organisation AD Scientific Index is more than an ordinary "Ranking". The "AD Scientific Index" analyses the academic work of scientists using the H-index, i10 index and number of citations, and provides results that can be used to evaluate the productivity and efficiency of individuals and institutions. In addition to ranking according to "total H-index" for individuals and institutions, you can also see the ranking and analyses according to "last 6 years H-index", "total i10 Productivity index", "last 6 years i10 Productivity index", "total citations" and "last 6 years citations" only in "AD Scientific Index". See also: Subject Rankings, University Subject Rankings and  Universities Rankings 2024 (Sort by: Last 6 years H Index).   Click here for individual or institutional registration.
