Manufacturing engineering education in India

Khare S., Chatterjee A., Bajpai S., Bharati P. K.

Management and Production Engineering Review

2016

Vol. 7, No. 1

40--44

Evolution of manufacturing technology has been a definitive indicator of human society’s development. From the wheels that started the spree to the world of machines that have revolutionized the manufacturing processes, manufacturing tools have been indicative of eras of development. In this paper, we have focused on the branch of engineering that deals with manufacturing - specifically its structure in India. In this study we investigate some premier government institutes with respect to Manufacturing Engineering Education. We have also included the technical education model at different education level.

Production engineering education in India

Khare S., Bajpai S., Bharati P. K.

Management and Production Engineering Review

2015

Vol. 6, No. 1

21--25

Present paper deals with the field of Production Engineering specifically its standard of education in India. This discipline of engineering focuses on the capability of an engineer not just as a technician but also as a manager. As a result industry is also favoring the development of this field. This paper reviews the educational structure followed in India for engineering education. It aims to give a clear idea of standard of this discipline’s courses being run in India at different levels of engineering, considering both centrally funded and private institutions. It also covers the necessary simulation tools used to train the students during these courses and inspects over available web-resources related to the subject. In the epilogue it discusses the future prospects for this field’s development as a discipline and concludes with a brief comparison of India’s status from other regions of world. In the end we have made some suggestions to decision-makers based on our findings to improve the existing model.

Enhancement in UV emission and band gap by Fe doping in ZnO thin films

Srivastava A., Kumar N., Khare S.

Opto-Electronics Review

2014

Vol. 22, No. 1

68-76

Enhancement of the optical band gap of ZnO from 3.14 to 3.29 eV has been obtained using Fe dopant. Undoped and doped ZnO films are deposited by sol-gel spin coating. XRD patterns indicate polycrystalline nature and hexagonal wurtzite structure of Zn₁₋xFexO films. EDX analysis confirms the presence of iron dopant. The photoluminescence spectra show an ultraviolet emission peak at 398 nm (NBE emission) and defect emission peak at 485 nm. Intensity of the NBE emission is much higher for the doped samples with its ratio to defect emission intensity highest for 2 at. %doping. The NBE emission shifts to higher energy with increasing dopant concentration in a manner similar to that exhibited by the band gap. Surface morphology has been studied using FESEM.
