MOSQUITO REPELLENT’-------A LITTLE ‘BIG’ THING.
Recently, I went to Guwahati to appear for an exam.
On my voyage, I came in contact with personal sellers of a certain type of repellant. She was neatly, officially dressed up, grin across her face, quite inspirational at the first look. She approached me and asked for a few minutes of my time. I was awaiting the due Network night-super schedule, so I agreed.
The next few minutes she took up all the efforts of explaining to me about the ‘mosquito repellent’ product she was selling. From our conversation, I came to know that she was not from the technical background, so she couldn’t explain about the internal principles of generation of the special ultrasonic wave which keeps the mosquitoes at bay.
I decided to carry the research myself and what I found out is a real simple laboratory principle…a basic electronics application. To know more about the working of these simple selling devices, download the pdf attached to this document. So that the next time you meet them, you should be explaining to them what they fail to explain to you.

FRONTIERS OF ECE WORKSHOP
The Electronics And Communication Engineering Department, NERIST is organising a Workshop on the fundamentals of Semiconductor Composition, fabrication and the internal architecture behind the modern nanoscale developments in fabrication processing.
It was a combined effort by the
"Institute of Radio Physics and Electronics"
University of Calcutta
(a diamond jubilee celebration program)
The workshop was on the "FRONTIERS OF ECE WORKSHOP".
The slides and the materials will be available on the blog within few days.
ANYONE INTERESTED IN ATTENDING THE SEMINAR CAN ATTEND IT TOMORROW FROM 9AM IN THE NEW SEMINAR HALL.

mY ConCept on "Perfection".
The essence of perfection is a novelty present within a human being.
The desire for success is a glamour which makes the essence.
The ability to see through simple equations make the simple desire alive.
The simple “ I CAN DO IT ” makes you doit, actuates your ability to do these things.
And it all happens if you give a simple try.
JUST GIVE A TRY ON SOMETHING YOU BELIEVE IN, BELIEVE IN YOUR THOUGHTS AND “SIMPLY DO IT”.
