A university’s position within the ranking is determined by the sum of D-indexes (Discipline H-index) of all affiliated scholars whose primary publication area is Mechanical and Aerospace Engineering. The D-index is calculated exclusively from publications and citation data pertaining to the specific discipline under examination, ensuring an accurate and discipline-focused evaluation of institutional research strength.
Scope of Research and Selection Criteria
The scope of the ranking is extensive and precise. In total, 279,971 scientist profiles from various bibliometric sources were examined, with a focused analysis on 66,807 scientists who have a primary research focus in Mechanical and Aerospace Engineering. The inclusion criterion for individual researchers was set to a minimum D-index threshold of 30, along with the expectation that the majority of their tier publications be within the field of Mechanical and Aerospace Engineering.
Special consideration was given to scientists’ awards and professional achievements in the field as an additional qualitative factor. The qualifying D-index threshold for inclusion among top researchers increases in increments of 10, calibrated to the number of scholars estimated per discipline, with a guarantee that the top 1% of leading scholars are always represented. Importantly, to ensure discipline specificity, a proximity of 30% or less is maintained between a scientist’s general H-index and their Mechanical and Aerospace Engineering D-index. Awards and recognitions further support the assessment of individual contributions.
Verification Practices and Data Reliability
The Research.com ranking team recognizes that raw bibliometric data, while informative, should not be the sole criterion for evaluating scholarly output. As a result, all scientist profiles underwent rigorous manual verification and were cross-checked with publications indexed across widely recognized and trustworthy sources.
It is also noteworthy that, while the total number of publications in prestigious journals and conference proceedings is not a primary factor for ranking position, it is nonetheless regarded as a valuable secondary indicator of a scientist’s overall impact within the discipline. The final position of each researcher is established according to their H-index, as aggregated from OpenAlex and CrossRef—two of the most respected and widely used bibliometric databases accessible to the research community.
