From the Desk of the Editor-in-Chief

It is a great pleasure for me to have been asked to shoulder the responsibility of acting as the Editor-in-Chief of the IETE Journal of Education (IETEJE) yet again (my earlier stint being 2012-2017). From 2017 to 2022, Dr PV Ananda Mohan and his Editorial Board Members did this job with the utmost sincerity and dedication. I am very grateful to them on behalf of the IETE JE as well as on my personal behalf.

This year, the Editorial Board has been reconstituted and I have been fortunate to have received the concurrence and the support of a team of highly renowned academicians and researchers as Editors from across the world, who very generously and readily accepted my invitation to join as Editors to spearhead the journal in its onwards journey.

We shall put up our best efforts for ensuring the publication of high quality content in a time-bound manner so that the journal is able to achieve Scopus/SCI/SCIE indexing and a good impact factor in near future. With the help of the Editors and the goodwill, support, and blessings of everyone involved, I sincerely hope that the visibility and reputation of this journal can be raised further. Professor S C Dutta Roy, DFIETE, deserves special recognition and mention for his longstanding commitment to and support of this journal and for being the most frequent contributor to this journal. My deepest appreciation goes out to him.

I extend my warmest appreciation to all of the esteemed Editors and welcome them all to the Board.

Scanning the issue

In the first paper of this issue, Iqbal and Singh demonstrate a methodology for teaching synchronisation of synchronous generators using a virtual laboratory developed by using various Simulation tools.

In the next article, Dutta Roy highlights two less known facts about lossy transmission lines, namely, (i) it is impossible to achieve perfect matching, i.e. the reflection coefficient, Γ, cannot vanish at any frequency and secondly, (ii) for such lines, the magnitude of Γ may show maxima and minima, but the overall envelope will only decay monotonically with frequency.

Misra in his exposition, starting from the invention of the radio waves traces the changing face of Public Broadcasting in India.

In his article Ravikumar shows how the use of simpler programming tools can be used creatively to deal with the topics such as design verification, validation, and testing of digital circuits and how these ideas can lead to improvement in digital design laboratories.

In power system analysis of critical faults, the different type of simultaneous faults on transmission lines is a sensitives issue. To identify the accurate fault place during a simultaneous fault condition, all major algorithms fail to provide the desired results. Tailor and Makwana, in their paper, carry out the analysis of simultaneous faults. With the help of equivalent sequence components, network generalized impedance equations are derived to determine the accurate fault place on transmission line during the simultaneous broken and fallen to earth conductors fault condition.

Aniley in his article, presents a comprehensive review on exit examination strategies and its role for enhancement of quality assurance and employability opportunity in engineering and technology programs.

In the next article, Sinha presents online course content for undergraduate students on full-custom design of digital VLSI circuits using open-source software. The approach is claimed to have helped the students in understanding full custom CMOS logic function design, test, and validation, with less effort and time.

In the last article of this issue, Rathore presents a successive method of deriving the necklaces of higher lengths from the lower ones where the absolute difference of two adjacent beads belongs to a specified set of numbers. This paper, is a sequel to his other papers on number theory published in some earlier issues of this journal.

Raj Senani

Raj Senani received BSc Engineering from HBTI, Kanpur, ME (Honors) from MNNIT, Allahabad and PhD from University of Allahabad- all in electrical engineering. Dr Senani became a professor at the erstwhile Delhi Institute of Technology, later renamed as Netaji Subhas Institute of Technology (NSIT) in 1990. He has served as head and dean of various departments at NSIT, dean of the faculty of technology of Delhi University and the director of NSIT, New Delhi, a number of times since 1990. He is working as an honorary professor of electronics and communication engineering at Netaji Subhas University of Technology (formerly NSIT) since June 2020.

Professor Senani’s areas of research interest include analog filters and oscillators, current-mode techniques, trans-linear circuits and chaotic oscillators. He has published a number of research articles in these areas in IEEE, IEE/IET and other international journals. He has been functioning as editorial reviewer for a number of IEEE, IET and other international journals. He has been an associate editor for Circuits, Systems and Signal Processing since 2003 and an editor/member of the Editorial board for a number of other international journals.

Professor Senani is a Senior Member of IEEE, a Life Fellow of IETE and an elected Fellow of the National Academy of Sciences, India (NASI). In February, 2012, he was bestowed with the Second Laureate of the 25^th Khwarizmi International Award for Fundamental Research. In 2020, 2021 and 2022, he was ranked among the top 2% scientists of the world in a report published by the Stanford University and Elsevier researchers. He was ranked among the top 1% reviewers of the world for engineering and interdisciplinary areas, for three consecutive years, namely, 2017, 2018 and 2019 by Publon (Web of Science). In 2021, he was given Eminent Engineer of the Year 2021 Award and a scroll of honor by the Institution of Engineers, India. Email: [email protected]
