Publish-Subscribe System:
- In the publish-subscribe system, an operation is persisted in a topic.
- In contrast to point-to-point system, the consumers may subscribe to many topics and then consume all the messages in those topics.
- The publishers are the message producers and subscribers are the message consumers.
Example:
A streaming service that publishes different channels such as movies, sports and music. People are able to subscribe to the set of channels that they want and get them whenever their subscribed channels are available.

using r language for integration theta = integral 0 to infinity (x^4)*e^(-x^2)/2 dx (1) use the density function of standard normal distribution N(0,1) f(x) = 1/sqrt(2pi) * e^(-x^2)/2 -infinity <x<infinity as importance function and obtain an estimate theta 1 for theta set m=100 for the estimate whatt is the estimate theta 1? (2)use the density function of gamma (r=5 λ=1/2)distribution f(x)=λ^r/Γ(r) x^(r-1)e^(-λx) x>=0 as importance function and obtain an estimate theta 2 for theta set m=1000 fir the estimate what is the estimate theta2? (3) use simulation (repeat 1000 times) to estimate the variance of the estimates theta1 and theta 2 which one has smaller variance?
using r language A continuous random variable X has density function f(x)=1/56(3x^2+4x^3+5x^4).0<=x<=2 (1) secify the density g of the random variable Y you find for the acceptance rejection method. (2) what is the value of c you choose to use for the acceptance rejection method (3) use the acceptance rejection method to generate a random sample of size 1000 from the distribution of X .graph the density histogram of the sample and compare it with the density function f(x)
using r language a continuous random variable X has density function f(x)=1/4x^3e^-(pi/2)^4,x>=0
