Twenty-five years study (1995–2019) of Food and Bioproducts Processing: An overview of research trends

In the current study, we presented an overview of the publication profile of Food and Bioproducts Processing (FBP), a leading international journal on food processing. The detailed analysis was made to measure its scientific progress from 1995 to 2019 by identifying publication trends, most cited articles, leading institutes, and profolic countries. The publication dataset and citations information were retrieved from the Scopus bibliographic database hosted by Elsevier. Several scientific achievements were observed in publications (n=1548), impact factor 3.726 or CiteScore 6.10, and the citations (a total of 33,663) over the 25-year time frame. The factorial analysis revealed that the journal research focuses on two clusters. The first cluster focused on moisture determination, spray drying, mathematical models, thermal processing foods, food products and food processing, and the second cluster focuses on research areas of the dimension of surface properties, organic solvents, response surface methodology, antioxidant activities, flavonoids, solvent extraction and fermentation. Although citations have increased significantly need wider publicity of the work. The most cited articles were identified with the interdisciplinary research within food science and technology and added to reinforce science advancement within the field. Overall, these findings highlighted the evolution, progress, quality, and efficiency of the journal and provided early-profession researchers/specialists with an opportunity to lead more inventive studies in food science and technology (FST)

Fifty Years (1970-2019) Journey of \u27Journal of Documentation\u27: A Scientometric Analysis of Research Productivity and Publication Trends

Purpose In this study, we conducted quantitative analysis of 1706 scholarly literature published in Journal of Documentation during the period of 1970 to 2019 (fifty years) using a series of scientometric indicators. Annual scientific production, most local cited sources, the ranking of authors; profiles, contributions, correlation, collaboration and authorship pattern, most contributed countries, most cited articles, frequently used search terms/keywords, and the legend of historiographic mapping were analysed in detail to measure the impact of the source. Design/methodology/approach We used the Scopus database for retrieving the desired sample data. In total, 1,706 numbers of publications records were considered for the literature analysis considering their relevancy. Biblioshiny data visualization tool is used to create the various maps. Findings The present study found that annual scientific production and average citations constantly have had an uptrend. The journal\u27s had tremendous impact with an h-index of 80, with a g-index of 148, total citations of 37,161 within the studied period. Although Bawden D contributed the highest number of research papers (n=78), the work published by Hjørland B received the highest citations. Lotka\u27s Law reveals that about 75.04% of the authors (1319 authors) have one publication, and approximately 12.73% of the authors (225 authors) have two publications. The United Kingdom was the dominant country in terms of number of papers and citation count whereas University of Sheffield topped with 128 publications. The thematic map consists of eleven clusters and ‘information retrieval’ found to be the largest cluster comprehending 56 subthemes occurring 995 times. Co-citation network identified four clusters with revealing Wilson TD as the most cited authors. The study also indicates the most collaborative authors are from the United Kingdom. Research limitations/implications The study exclusively deals with 1732 published research literature indexed in the Scopus database covering a span of fifty years (from 1970 to 2019). Thus, documents which are not covered in Scopus are excluded from the purview of research. This study is significant in order to measure the impact of Journal of Documentation and useful to identify valuable research patterns from publications and of developments in the field of Information Science

Procjena prijelazne stabilnosti dvopodručnog energetskog sustava s CSC-STATCOM-om zasnovanom na LQR-u

A current source converter (CSC) based static synchronous compensator (STATCOM) is a shunt flexible AC transmission system (FACTS) device, which has a vital role as a stability support for small and large transient instability in an interconnected power network. A robust linear quadratic regulator (LQR) based controller for CSC-STATCOM is proposed. In this paper, LQR based CSC-STATCOM is designed to enhance the transient stability of two-area two-machine power system. First of all, modeling & LQR based controller design for CSC-STATCOM are described. After that, the impact of the proposed scheme on the test system with different disturbances is demonstrated. The feasibility of the proposed scheme is demonstrated through simulation in MATLAB and the simulation results show an improvement in the transient stability of power system with CSC-STATCOM. Also, the robustness and effectiveness of CSC-STATCOM are better rather than other shunt FACTS devices (SVC & VSC-STATCOM) in this paper.Statički sinkroni kompenzator (STATCOM) zasnovan na pretvaraču strujnog izvora (CSC) je uređaj za izmjenični prijenos s fleksibilnim "shuntom" (FACTS), koji značajno doprinosi stabilnosti malih i srednjih prijelaznih nestabilnosti u međusobno povezanoj energetskoj mreži. Ovdje je predložen robusni sustav upravljanja zasnovan na linearnom kvadratičnom regulatoru (LQR) za CSC-STATCOM. U ovom radu, CSC-STATCOM zasnovan na LQR-u dizajniran je za povećanje stabilnosti dvopodručnog energetskog sustava s dva motora. Prvo su opisani postupak modeliranja te upravljački sustav zasnovan na LQR-u za CSC-STATCOM. Nakon toga, prikazan je utjecaj predstavljene sheme na ispitni sustav uz prisutnost različitih poremećaja. Provedivost predstavljenog pristupa je prikazana kroz MATLAB simulacije čiji rezultati prikazuju poboljšanje u prijelaznoj stabilnosti energetskog sustava s CSC-STATCOM-om. Također, u ovom radu je prikazana veća robusnost i efikasnost CSC-STATCOM "shunt" FACTS uređaja u odnosu na SVC i VSC-STATCOM

Scientific publications originated from china received highest citations (55,688) followed by USA (13,996) and Hong Kong (9,501). Although ‘New England Journal of Medicine’ published the most papers (n=15) with the highest impact factor value of (74.699) but studies published in ‘The Lancet’ has received highest citations (n=18,431). The top five journals hold 44% of these influential studies. The Tongji medical college, Huazhong University of science & technology, Wuhan, China is the top institution with the most T100 articles in the field of Covid-19.
