Best Mechanical and Aerospace Engineering Scientists in Pakistan

The 2nd edition of ranking of the best scientists in the discipline of Mechanical and Aerospace Engineering is based on data derived from a wide range of data sources including OpenAlex and CrossRef. The bibliometric data for devising the citation-based metrics were collected on 21-12-2022. Position in the ranking is based on a scholar’s D-index (Discipline H-index), which takes into account only papers and citation values for an examined discipline.

The focus of our Mechanical and Aerospace Engineering research’s best researchers ranking is a trustworthy lineup of leading scientists from the area of Mechanical and Aerospace Engineering, based on a meticulous examination of 166,880 scientists determined from multiple bibliometric data sources. For the discipline of Mechanical and Aerospace Engineering, as many as 5741 scholars were analysed.

What is D-index acceptance threshold for Mechanical and Aerospace Engineering
The D-index threshold for accepting a scientist to be examined is placed at 30 if the majority of of their publications are in the field of Mechanical and Aerospace Engineering. The inclusion criteria for scholars to be considered into the ranking of top researchers are based on the D-index, proportion of the contributions made within the given area plus the awards and achievements of the scholars. The D-index threshold for considering top scholars is set as an increment of 10 depending on the overall number of researchers projected for each scientific field whilst guaranteeing that the top 1% of best researchers are added into the list. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.

Additional verification practices
Since our leading aim is to guarantee that only actual scholars are listed in our ranking we realize that metrics are never meant to be an absolute tool to quantify the output of scientists. Because of that we manually inspect each profile and cross-correlate it against publications in a wide range of credible sources. While it’s not a factor impacting a researcher’s position in the ranking, the number of papers published in major journals and conference proceedings should be a credible secondary indication of their contribution to research in a specific field of study. Position in the ranking is determined by each researcher’s D-index with the help of data compiled from OpenAlex and CrossRef, which are the most prominent and well-known bibliometric databases of this kind accessible to the scientific community. A detailed explanation of our research process can be found on our methodology page.

Our goal
Our objective is to motivate scientists, businessmen and decision-makers around the world to explore where leading experts are heading and to give a way for the entire research community to find out who the leading experts in specific areas of study, in various countries, or even within research institutions are.
