To produce high quality engineering graduates
with the requisite theoretical and practical
knowledge and social awareness to be able to
contribute effectively to the progress of the
society through their chosen field of endeavor.
To undertake Research & Development, and
extension activities in the fields of Science and
Engineering in areas of relevance for immediate
application as well as for strengthening or
establishing fundamental knowledge.
F O R E W O R D
Two batches of students have successfully graduated from the M.Tech.
programmes under autonomous status, which gave us a lot of
satisfaction and encouragement. In the light of changing scenario of
accreditation process globally, to upkeep the quality of education
further, a major revision in the curriculum has been taken up with an
objective to provide outcome based education.
We could execute these changes through our dedicated faculty,
commendable academicians from institutions of repute, enthusiastic
representatives from Industry, affiliating University JNTU-K, and UGC
present in the Boards of Studies, Academic Council and Governing
Body.
It is hoped that the new regulations and curriculum will enhance the all-
round ability of students so that they can technically compete at global
level with native ethical standards.
