“There are times when silence speaks so much more loudly
than words of praise to only as good as belittle a person, whose
words do not express, but only put a veneer over true feelings,
which are of gratitude at this point of time.”
On the very outset of this project, I would like to extend my sincere & heartfelt obligation towards all
personages who have helped me in this endeavor. Without their active guidance and help, cooperation &
encouragement, I would not have made headway in the project. The success and final outcome of this
project required a lot of guidance and assistance from many people and I am extremely fortunate to have
got this all along the completion of my project work.
I am ineffably indebted and extremely thankful to Mr. Santosh Kumar for giving me the opportunity to
work on this project and for his conscientious guidance and encouragement to complete this project.
I owe my profound gratitude to our project guide Mr. Suman kumar & Mr. Deepak , who took keen
interest in my project work and guided me all along, till the completion of my project work by providing
all the necessary information and supervising me through all the processes involved. Working all along,
under their supervision brought me immense knowledge both practically and theoretically which would
be of great help to me ahead in my life.
I also acknowledge with a deep sense of reverence my gratitude towards my parents and member of
family, who have always supported me morally as well as economically.
At last but not least gratitude goes to my friends who directly or indirectly helped me to complete the
project. Any omission in this brief acknowledgement does not mean lack of gratitude.
THANKING YOU -Divyaansh Mehta
