Teachers day 5 sept 2017

it was on 4th September 2017 when we had the onam celebration with my Kerala friends. the lunch was supposed to be start from the 2pm . and the planning was to go to the lunch and after that we had the nonlinear control class of bhasin sir which is the one of the best class in IIT delhi control and automation. but due to delay lunch started at 4.30pm and we had to miss the class of bhasin sir . and after that our phd seniors planned to celebrate teachers day and they told to shantak and sanjeev about it. so they called us and we reached the control lab by 5;30 pm. then they told me to make something for the teachers they were just telling me to make some invitation card for the faculties.

initially i was like i will not give my time in this but within half hour i decided that if these people are believing in me thats why they are telling me….and if i will not do it then who will??

i can bring a change here i will make it…then at 6 pm i told them that i will make e.invitation and we will take print out of it and give them as the invitation. and i left the lab by saying that i am going to start my work. and directly went to the library and spent 1 hour time to decide about the invitation card ..one thing was very clear that it will be a surprising for them all. i searched the youtube video and found some ideas but that was time taking .i really wanted to make all those but i had limited time to complete my task.

so i googled about the e invitation in google and found one website . where templates were there for various invitation. i just started making the templates there using the photos of the faculty and then i did all this till 12 o clock at night and i thought that if we will give just a printout of this then it will not be that good so why cant we frame it and give them as a memento. because this will stay with them for the lifetime. and in the night i tell about my plan to shantak than he told that it will be ok . but he was not knowing about the framing of the photo and all so he told me to do it by my own. but the problem was that next day i had swimming practice from morning 6 to 7 then i had 2 class then after that i had TA duty also so my entire day was pack. but i thought that i will make it happen no matter what,if i have to miss the class then i will miss it for teachers no problem at all.

next morning i went to ber sarai and munirka to find a frame for that and after some struggle i found a shop where i got 7 frame 100 rs each .then i took printout and made that all photos with my hand only i dont wanted for anybody to help me for that purpose,

i came to lab at 4.30 pm and everybody was very very happy with my work everybody told me that i have done an amazing work they were apprecited my throughout the event. and arnov sir who was a phd student was anchoring the event mentioned my name in front of the whole department and everybody including the faculty clapped for me. it was an awesome feeling that time . faculties also liked that gift very much because there were not any event like this before. i will remember this teacher day for my lifetime with lots of learning with me.

what i have learned from the day-

  1. if you have any talent then show this to the world, share it with the people around you.
  2. if you do something good then its satisfaction level is uncomparable
  3. everybody likes appreciation no matter what so appreciate others for there good work in unique way so that they will remember you for the lifetime
  4.  i will give thank you latter to some of the people in india for there good work in unique way,,may be in same way as the memento for this faculty because this will motivate them to do good work and ultimatelly it will benefits the society itself and with onky 120 rupees.

  6. take responsibility for something to do.
  7. people will try there best to take credit hence do it all with yourself only because you are very much capable of doing that
  8. photo frame size was 5*7 inches so make portrait according to that only.
  9. in next teachers day perform a song with the guitar and small emotional speech

Rally for rivers

a land is identified as a soil if it hase atleast 2% of organic content. we are farming sugarcane and that is using this organic content of the soil. many states including punjab and haryana has land which has less than 0.05% of organic content.

we are taking out the organic content but not giving it back to the soil. the process by which this organic contect can be increased is by the waste of the animals and the leaf of the trees. trees are gone and animals are being sold as the meat. so in near future all the land will become desert.

we must save the rivers because this are the way we can save the soil and organic content in it.

DFO interview experince

the reporting time was 9 am so i reached the dadar by 8.30 and did my breakfast there and went out from the dadar station and i was was being nevigated by the google map to the interview venue then there was flower market outside the dadar station which smell very good at the morning.

they gave a page to write down the resume in about 15 lines then the CPT started at 10 am and i wrote down whatever they have asked . i searched for the canteen there and found one but they were only giving full meal and that was beyond my capability so i went outside and searched for something to eat and i met up with one dabeli wala there and bought 2 dabeli and that was sufficint for that time . at the same time i talked to rupesh and he give me some advice and some latest news of current affairs that can be asked in the interview, that topic covers the doklam issue and about the new president of india ramnathkovind and some general issue. then we waited so long for the interview and they send back some of the candidates of mumbai because interview was not going to end in single day.

second trip to mumbai

it was 17 august 2017 in the iit Delhi campus . i have to go to the Mumbai to attend an interview for the post of deputy field officer in the cabinet secretariat govt of India. interview schedule was at morning 9 am at the dadar Mumbai.

i attended all the lecture except the nonlinear control in the evening because i had to make some correction in my resume , i made some mistake in that and last date for document verification was in 28 august so anyhow i had to give more priority to that resume part. hence i did that till evening and after that i came to the hostel and started packing the things which i wanted to take with me to the Mumbai. i did my dinner and went out to book some uber cab through my brother rupesh wallet so that i can get some 50 rupees off on the first ride and for this i wasted some important time .

at 8 o’clock i decided to go by the metro but it was too late and my train was at 9.30 from the hazarat nizamuddin. i got an auto that will drop me at the hauz khas metro station then i thought tha why cant i book this auto for the entire journey to the hazarat nizamuddin and i asked him if he will go the station and he agrees but he told that he will charge some 150 rupees and i told no problem because i did nit had any other option that time. but in between i got stucked in traffic and for a while i thought that it will not be possible for me to reach the station at 9.30 pm. i was very scared but somehow traffic jam gets clear and i started praying that please god for this time make it clear and believe me it was like a magic, god was with me always that time i rarely stuck at any signal that time and i reached to the station at 9 pm. i thanked the auto walas and started my journey .

and then next evening at 6 pm i reached the bandra terminus of Mumbai and from there i had to go to the dadar then thane and then rabale. i took ticket from the bandra terminus and followed the procedure and by 7 oclock i reached at the bhoomi palace flat number 203 ghansoli navi Mumbai. and after some time sumit and his roommates came after that we discussed about the future plans and about his ms, and by late night i slept and woke up early in the morning and got ready by 6.45 am. and i took local at 7 am from ghansoli to dadar and i reached the exam venue by the time 8.30 am. then there was CPT and after that i had given my interview that all happened by the evening 7 pm. and i did my dinner and took local for the dadar station and made a big mistake that time.

my train was from Mumbai central but i was so happy that i thought it is from the CST and i took local for the CST and by the 9 pm i reached the CST. then i realized my mistake and i was totally feeling stupid that time because my train was at 9.25 pm from the Mumbai central and i was at CST at 9 pm. i had only 25 minutes left in which i had t o go to the Mumbai central station. fortunately i got a fast local from the CST to dadar and i reached  dadar at 9.10 pm from there i got a local at 9.14 pm which landed me to the Mumbai central at 9.23 pm. i was in a rush because i dont wanted to miss my train second time . i was runing on the platform everybody was thinking that what happened to me but fortunately i reached the platform number 1 by 9.25 pm. i was running and train started and suddenly i jumped to the S5 as it was close to me that time and my seat was in the S7 67 then finally i reached my palace . i was very happy that time . that happiness i can not explain because i did not missed the train second time from the same palace, because one time mistake is allowed but if you do same mistake second time then it is stupidity nothing else.

banipali,population etc

farming what kind of forming you do

electronics and telecommunication

control and automation



bluetooth uses phase shift keying to exchange data.

combination of phase shift keying and amplitude shift keying is called QAM(quadrature amplitude key)


The Internet is a worldwide network of computers and computer networks that communicate with each other using the Internet Protocol.Any computer on the Internet has a unique IP address that can be used by other computers to route information to it. Hence, any computer on the Internet can send a message to any other computer using its IP address. These messages carry with them the originating computer’s IP address allowing for two-way communication. The Internet is thus an exchange of messages between computers.[85]

GSM==>global system for mobile

CDMA==>code division multiple access

voLTE==>voice over LTE, you can transmitt call in hd quality over 4G network. initially this voice improvement were not taken care by the improvment from 2G to 3G and then 4G.but here they have taken care of. to use it properly both transmitter and receiver should have voLTE. and your network provider should also give this service.

Electronics in defence==>electronics is always a important part in defence may be it enabling communication, information gathering and navigation.



  • radio detection and ranging
  • used for navigation, air traffic control,mapping and meterology
  • the time defference between the transmitted signal and received signal find the distance. and the orientation of the radar also determines the direction,it uses the doppler effect to do its job
  • DOppler effect==> if anyobject is producing and signal and if it is moving then based on the which direction it is moving the frequncy of the signal changes for the stationary observer. if it is comming towards the observer then its frequncy becomes high and if it it is going away from the observer then its frequency becomes low . for a sound wave frequency refers to the pitch hence we hear a sound of high pitch if it is coming towards us.
  • SONAR is used in the ships to detect either the mountain inside or either to detect the depth of the sea
  • application of doppler effect==>sonar, radar, to estimate eithers stars are moving towards the earth of going away from the earth. if it go away then called redshift and if it comes towards then called blueshift



  • carrier frequency=300kHz to 3MHz range
  • AM=100Hz to 5 kHz
  • effected by sunlight, electrical interference,lightning and buildings
  • FM==>
  • 88Mhz to 108Mhz
  • it is les effected by the EMF

in their area one or two are king and 1 or 2 are queen which are futile rest others are infurtile. when they produce new larva then they select some specific larva and feed them very well so that the can become the king and furtile bee. they dont do it for all the larva.


after bitting they die out.
