Abstract 

This report examines the research output of the journal "Indian Journal of Engineering and 

Materials Sciences (IJEMS)" between the years 2001 and 2018, focusing on a subset of the total 

1215 papers published in the magazine. The year 2014 saw the greatest volume of published 

works. Researchers most often used journal articles as references in their work. There were 10,952 

papers published with two or more authors and just 120 published with a single author. The 

Relative Growth pace of academic communication is 1.99, which means it is growing at an 

average pace. This study indicates that IJEMS's research output and growth rate of scholarly 

communication are on the decline, and it also looks at the authorship pattern of this 

communication using the collaborative index, which is the collaborative coefficient. 

Keywords: Science, technology, engineering, and mathematics (STEM), and scientometrics 

 

 

 

 

Introduction 

Scientometrics is a field that uses the analysis 

of scientific papers to learn more about how 

science works and how it develops over time. 

The quantitative and qualitative features of a 

publication are dissected using bibliometric, 

scientometric, and informetric methods. 

Quantitative measures of scientific information, 

such as the number of scientific articles 

published in a given time period, the citation 

impact of those articles, etc., are used to 

examine the development of science in this 

discipline (Rajendran, 2011)."Scientometrics" 

is the "application of those quantitative 

methods dealing with the analysis of science 

viewed as information processes," as stated by 

Patra et al. (2006). The Indian Journal of 

Materials Science and Engineering Launched 

in 1994, the journal features articles from a 

wide range of engineering disciplines, 

including aerospace, mechanical, metallurgical, 

electrical/electronic, civil, fluid mechanics, 

instrumentation, and materials science. As of  

 

the year 2018, the IF of IJEMS was 0.794 

(JCR). 

(http://op.niscair.res.in/index.php/IJEMS/index

) The mission of the Indian Journal of 

Engineering & Materials Sciences is to 

disseminate significant new findings in the 

theory and application of all branches of 

engineering and materials science. Aerospace, 

mechanical, metallurgical, electrical, 

electronic, civil, and materials engineering are 

all subfields of engineering.

nst_auth.pdf). 

 

The objective of the Study 

 To study the growth of research 

productivity on during 2001-2018. 

 To examine the Relative growth 

rate of articles. 

 To find out the Doubling time of 

the articles. 



 

 

 To analyses the Author pattern and 

collaboration like CI, CC, DC, etc., 

 To know the ranking of the author. 

Scope and Methodology 

The paper represents 

the scientometric analysis of 

IJEMS publications in the field 

of engineering during the 

period 2001 to 2018. The data 

is confined to articles on 

IJEMS. A total number of 

1215 articles have been 

found and the same has been 

analyzed by   using the

 spreadsheet

 application.

 Computed growth rate and collaborative measures using a set of formulas. 

 

Analysis and Interpretation of Data 

 

Analysis of the data 

based on the publishing 

chronological order from the 

year 2001 to 2018. Using 

worldwide set of formulas i.e. 

Log formula and mean value 

the study analyzing the Author 

collaboration i.e Collaborative 

index (CI), Collaborative 

coefficient (CC), Degree of 

collaboration (DC) also 

Average Author per 

publication (AAPP) and 

Average publication per author 

(APPA) etc., also examines the 

Growth rate of scholarly 

communication through 

Relative growth rate (RGR) 

and Doubling time (Dt).

Table-1 show that the 

growth rate of research 

publication on IJEMS between 

2001 and 2018 in terms of 



 

 

Relative growth rate (RGR) and 

Doubling Time (DT). Mean 



 

 

value of Relative growth rate and 

doubling time is 2.14 and 0.39 

respectively. It is evidenced that 

the Relative growth rate increased 

whereas the Doubling Time (DT) 

slightly decreased.

Findings and Conclusion 

The Relative growth rate 

(RGR) has an increasing trend 

whereas the Doubling time (Dt) 

has increasing trend. Average 

doubling time was 0.37 years. The 

Mean number of authors (CI) was 

3.5 Highest author collaborative 

coefficient is 0.67 in the year 

2018. The average Degree of 

Collaboration (DC) was 0.90. 

Average author per publication 

(AAPP) is high i.e. 3.03, Average 

publication per author (APPA) is 

very less that is 0.33. There is 

collaborative research trend in 

IJEMS. 

Scientometrics analysis of 

a subject field helps in 

identifying the research status. It 

can be seen whether it is 

conducting more or fewer 

research works in a particular 

field. 

Through this analysis, one can 

found subject areas in which 

research trend is high and the areas 

where research trend is low; and 

subject areas where no significant 

change in research is seen world-

wide.
