Data Sources and Methodology Overview
The 4th edition of the Research.com Best Mechanical and Aerospace Engineering Universities in Thailand Ranking has been meticulously developed using a robust suite of data sources, the foremost being OpenAlex and CrossRef, complemented by numerous other reputable bibliometric datasets. The core of the ranking’s citation-based metrics was constructed from comprehensive bibliometric data collected as of 2024-11-27. The primary metric determining each institution’s placement is the sum of D-indexes (Discipline H-index) attributed to all qualifying scholars affiliated with a university whose principal scholarly output lies within Mechanical and Aerospace Engineering. The D-index is uniquely rigorous in its focus, including only publications and citation data pertinent to the specific discipline under assessment.
Scope of Research and Scholar Selection Criteria
The ranking’s analytical breadth is substantial: 279,971 scientist profiles from diverse bibliometric sources were initially reviewed, from which 66,807 specialists in Mechanical and Aerospace Engineering were meticulously analyzed. Eligibility criteria for inclusion demanded a minimum D-index of 30, with the majority of a scientist’s top-tier publications grounded in the discipline of Mechanical and Aerospace Engineering. In conjunction with publication metrics, scholarly awards and field-specific achievements were integral to evaluation. To ensure accurate representation of the field’s foremost experts, the D-index threshold for top researchers was calibrated in increments of 10, tailored to the estimated scholar population per discipline, while always encompassing at least the top 1% of leading scholars in each field. For further precision, the proximity between a scientist's general H-index and their D-index was required to be within 30%. Additionally, the scientific distinction—reflected in awards and professional recognition—was a significant consideration within the selection process.
Additional Verification Practices and Data Integrity
Recognizing the inherent limitations of raw bibliometric data, Research.com undertook rigorous verification protocols. All profiles of scientists were manually reviewed and cross-referenced against publications in a broad spectrum of reputable and trustworthy sources. While the mere volume of papers published in top-tier journals and conference proceedings does not directly influence a researcher's position in the Research.com ranking, it remains a valuable supplementary indicator of scholarly impact within the field. Ultimately, the definitive ranking position was established via the sum of individual scientists’ D-index values, relying on data from OpenAlex and CrossRef—two of the most prominent and authoritative bibliometric databases available to the academic community.
