R&AW==>from 1923-1968 IB was responsible for the intelligence collection from the other country and its purpose was totally because of the countary security. this was created by the british but after second world war work load was incresed significantly on this aggency hence govrt needs to create a new aggency to look on this matter and then this RAW comes into the oicture.

form 1968 onwards RAW is active which has following objective=

  1. to monitor political,military,economic and scientific development which has the direct bearing from the national security.
  2. moulding international public opinion and influencing foreign government with the help of strong indian diaspora
  3. anti terror operation and neutralising terror elements
  4. to watch the development of international communism and schism between worls two biggest communist nation soviet union and china.
  5. to control and limit the supply of military hardware to pakistan from the europion countary, america nd most importantaly from china.Structure_of_Research_and_Analysis_Wing_RAW

It is claimed that Chhattisgarh takes its name from the 36 ancient forts in the area.

Another view, more popular with experts and historians, is that Chhattisgarh is the corrupted form of Chedisgarh which means Raj or “Empire of the Chedis“.In ancient times, Chhattisgarh region had been part of the Chedi dynasty of Kaling

banipali,population etc

farming what kind of forming you do

electronics and telecommunication

control and automation

telecommunication==>

transmitter,channel,receiver

bluetooth uses phase shift keying to exchange data.

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

INTERNET

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.

 

RADAR==>

  • 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

 

 

 

 

cabinet secretariat

it provides secretarial assistance to the cabinet ministers. when they go for a meeting they provide secretariat.

i meeting…the document should be presented.

cabinet secretary(CS) is head of cabinet secretariat.

CS is senior most IAS officer. he does not hold any particular department(unlike other secretary)

they suck the flower and eat them then this thing will mix with the engyme inside their stomach and finally they vomit them then when moisture is out then this become the honey. they also eat it but they produce it more than their requirements so othersa as human also use this things.

 

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.

 

unique species

 

wine==>>made of fruits, generally graps

28.07.2017 matlab differential equations

  1.  dsolve===>> to solve linear differential equation, just write the equation in inverted comma and initial condition also in inverted comma. to assign value of answer you can use variable name in big bracket in left hand side.
  2. solve==>>to solve any number of equation
  3. vdp1==> is vanderpol oscillator with mu=1. you can directly use this to solve
  4. to solve nonlinear differential equation you can use ode45, see the syntax

28.07.2017 matlab

feval==>it will evaluate a function and gives output depending upon the input. input may be in n numbers and output may also be in n numbers.

write a function then use this your function or function from library in inverted comma or with the @ symbol and follow the syntax.

to know the size of a matrix you dont have to use ‘r ‘and ‘c’ to store the row and column instead enter some any other variable.

‘find’ function will give the linear index of the matrix so use accordingly.

 

 

28.07.2017 matlab project

problem is that there are F matrix which has 12 elements and one S matrix which has 10 rows. and according to the maximum element of F, elements of S should be adjusted. means this number should be same for the both.

 

thats why there is index exceed matrix dimension is occuring.

F has more number of elements because initially it stored some numbers of elemnets then there should be elimination of elements in S. so dimension of S will decrease but F has same dimension. so solution for this problem is that every time reset the F variable. but when resetting, then we cant eneter the interval in to it bcz it again shows the error that conversion from interval to double is not possible. so any how i have to reset the F. then problem will be solved.

 

finally problem solved  🙂

according to the location found in I_elim i was removing the elements in S, but after removal of the elements, location of desired elements also changes. as if it was in 5th location then after removal of 1 element it will move to 4th location. this problem should be considered. after adjusting the elimination location also , i solved the problem

27.07.2017 programming

every day only one problem is enough. select one problem and try to solve it using the c++. this will be of great use in future.

make a flow chart first for any problem then start coding for that problem. it will make your work very easy.

recall all the knowledge you have gained till that and repeat them only, till you become master on that.

27.07.2017 control system

every practical system is a nonlinear system . so we have to understand the control of this systems . this systems can be approximated to a linear system and controlling of linear system we know very well, we can do pole placement according to our desired response criteria.

so nonlinear system can be approximated to linear system at the equilibrium point. equilibrium points are the points where all states are constant or not changing, find that point and linearize the system for that point and do the rest of the analysis same as the linear system.

stability can be BIBO stability or stability in terms of the equilibrium point, in BIBO stability for a bounded input there should be a bounded output but for stability in sense of equilibrium point there should be convergence of system should be present when we disturb the system means system should come back to the equilibrium point if we disturb the system. this is useful when we don’t know the input for the system then we can use this stability condition.

solution of the any LTI system we know that is the addition of the zero input response and zero state response. for the stability of the system this both response sound be bounded. if we solve this one then we can see the exponential term in that so if it decays then it will decay exponentially. that is called asymptotically stable, hence the exponential stability and asymptotically stability are same. either it will decay asymptotically or it will be unstable.
