Question 1
A thermal engineer is studying a heat exchanger where the inlet temperature can vary randomly. How would they use stochastic PDEs and PDFs to model this uncertainty?
💡 Hint: Think about how randomness affects the equations governing the systems.
Question 2
In a communication system, the designer assumes that the noise follows a Laplace distribution instead of Gaussian. What impact could this have on bit error rate predictions?
💡 Hint: Consider the role of distribution type on the results.
