A scientist’s position in this ranking is determined based on their D-index (Discipline H-index), a refined metric that exclusively considers publications and citations within the specific discipline under evaluation—in this case, Mechanical and Aerospace Engineering. This focused approach enables a discipline-centric assessment of research impact, filtering out contributions outside the field to accurately reflect domain-specific scholarly influence.
Scope and Eligibility Criteria
In developing the ranking, a comprehensive examination was conducted across 279,971 scientist profiles identified from a broad array of bibliometric sources spanning all scientific disciplines. From this broad survey, 7 scientists specializing in Mechanical and Aerospace Engineering in Vietnam were specifically identified and evaluated.
To qualify for inclusion, each scientist was required to have a minimum D-index of 30, reflecting a significant volume and citation impact in Mechanical and Aerospace Engineering publications. Additionally, a majority of an individual’s tier publications needed to be rooted in this discipline. Beyond quantitative metrics, consideration was also given to awards and other notable achievements within the Mechanical and Aerospace Engineering field.
The D-index threshold methodology is adaptive, set in increments of 10 based on the estimated total number of scholars in each discipline, thereby ensuring that the ranking captures the top 1% of leading experts in the area. An important quality control measure was to maintain a proximity of 30% or less between a scientist’s general H-index and their D-index, safeguarding against disproportionate disciplinary bias.
Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot fully encompass the scholarly contributions of researchers, the team behind this ranking conducted a thorough manual verification of all scientist profiles. Each profile was cross-correlated against publications documented in a wide range of trustworthy and recognized sources to ensure accuracy and reduce data anomalies.
While not directly influencing positional rank, the number of papers published in prominent journals and conference proceedings was also reviewed as an important secondary indicator of a scientist’s stature and contribution to Mechanical and Aerospace Engineering research.
The ranking positions ultimately reflect each researcher’s D-index based on data integration from OpenAlex and CrossRef—the foremost bibliometric databases widely utilized by the global research community for such analytical efforts.
