Challenge of the Week

Hello Friends,

Sorry for not being in touch for so long....i know exams are coming up for the present students...and they are too busy with their preparations....ALL THE VERY BEST to all of you....

Continuing our trend of mind boggling puzzles....i am shooting you here with a small question...lets see which one among us answers it first....

The Question is:

Put two charged (one positive and the other negative)conducting plates facing each other at a distance of 10 cm. Assume the charge in each plate is 1 Coulomb and each plate has dimensions of 5 cm by 5 cm. If you discharge this capacitor certain amount of energy is released (the spark).

If, before discharging the plates, you pull them apart to reach 15 more centimeters, the energy released when discharged will be smaller or bigger than in the first case? Explain.

Waiting for the answer.........

Take Care....

Presentations

Hello Friends,

A great collection of presentations prepared by the electronics students including the prize winning presentation on Biometrics by Anmol and Migmar have been uploaded on the undermentioned link......

Another Prize for Us.......

Hello Friends,

I guess this year is fully loaded with achievements, achievements and more achievements....we had not been able to come out of the happiness and celebrations for VI MANTRA 2008 that another PRIZE came in to our arms......The Prize this time is for a 10 minutes paper presentation in a contest called......

CONVERGING VECTORS
Inter- College Paper Presentation Competition
Held on 13th December 2008
Organized by ARYABHATTA SCIENCE FORUM,
Deen Dayal Upadhyaya College, University of Delhi.

The event had participation from a lot of colleges in Delhi University and people had great topics to present. The event also included great participation from our own college in the field of electronics. 5 different papers were selected for participation after final scrutiny among the entries from the electronics department in ANDC.....The event also had two other categories....Physics and Computer Science.....both categories involved overwhelming participation from ANDC as well as other colleges....

The great news is that in the category of Physics and Electronics....ANDC beat all the other participants and stood first among the others thus winning a cash prize of 1000/- each apart from the certificate of prize.

Our heroes from Electronics are ANMOL BAGGA and MIGMAR DOLMA.....from B.Sc.(H) Electronics-III.........Both of them as a team made a presentation on BIOMETRICS. However, the topic was presented by ANMOL BAGGA which fetched us the first prize.......

3 Cheers for ANMOL and MIGMAR........Hip Hip Hurray!!! Hip Hip Hurray!!! Hip Hip Hurray!!!

Well done guys....keep rocking........ELECTRONICS ANDC ROCKS!!!!!!

Great News!!!!!!!!

Acharya Narendra Dev College is proud of our students and teachers of Electronics who have won the third prize at the very prestigious National Instrument's paper contest VI Mantra 2008 in the student category.

The work reported in the paper 'Study of Hall Effect using LABVIEW' emanates from the project done with our B.Sc. (H) Electronics-III^rd year students - Anshul Vinay Parmar, Migmar Dolma and Rohit Gambhir - with Dr. Amit Garg, Ms. Reena Sharma and Mr. Vishal Dhingra in the Department of Electronics. It was a tough competition where 107 entries were shortlisted in the student category from submissions received from about 800 reputed Engineering colleges in India. We then went on to win the third prize which is an accomplishment since we were competing with best engineering colleges in the country.

The students were taken to Bangalore and provided accommodation in a five star hotel to attend the Prize distribution ceremony on NI Educators Day 2008 in Bangalore by the organisers. Besides, the students will get a chance to present this paper to Industry Experts at the 7^th National Conference on Virtual Instrumentation in Engineering Education 2008 to be held in New Delhi. As part of the prize, we have also received the Student Version of LabVIEW and certificates from National Instruments to all the authors. They have also won 1000 USD from National Instruments for Lab up-gradation. We can proudly announce that its only the second time in 6 years that any team from North India has won any prize at this prestigious event. The earlier winner from this region was in 2002 and he is now working with National Instruments.

Congratulations & Celebrations!!!!!

Hello Friends,

This is celebration time for all us..........our friends have made us feel so so proud of them.....four of us, namely Ankit Dwivedi, Divya Bisht, Nazim Ali and Nidhi Saxena, Electronics-III were selected to give a poster presentation at a national conference MATEIT 2008, Second National Conference on Mathematical Techniques: Emerging Paradigms for Electronics and IT Industries. They presented their paper with the name of "Understanding L-I Characteristics of Light-Emitting Diodes and Laser Diodes". They got a very overwhelming response at the conference and their poster was considered among the best of all the posters displayed in the conference. The poster will soon be now put to display in the Electronics Lab for visitors. Three cheers for all of them.....Hip Hip Hurray...Hip Hip Hurray....HIP HIP HURRAY!!!!!!!!!!

Hey friends, do not stop your cheers right away, there is more news coming ahead.....a contest was organised by National Instruments in India by the name of VI Mantra 2008. Entries were invited from over 850 colleges in India and 50 were selected for publication. I proudly announce that three of us, Anshul Vinay Parmar, Rohit Gambhir and Migmar Dolma, Electronics-III submitted an entry to the contest which has now been selected among the best 50. Great going friends.....They are currently working on the development of the VI and its full paper to be sent by 25th Oct 2008 to National Instruments for publication......For those of you who are unaware of what a Vi is, it might be thought of as a software based data acquisition program which when interfaced with the external set up can be used for performing experiments and their analysis in the laboratory. We are eagerly awaiting the release of the VI which will then be used for experimentation by the Electronics-I students to study the Hall Effect.

We should now be looking forward to some more glory to the department as the second year students have tied up their belts and are working on some extremely interesting research based projects. All the best to all of them.

Keep blogging and visiting the blog for more of great news and please please do share your technical knowledge and experiences with all of us.....

Have a great time ahead....
