1. Let A[0..n-1] be an array containing a bitonic sequence of n distinct numbers. A sequence is called bitonic if it consists of a decreasing sequence followed by an increasing sequence. For example, 9, 5, 3, -1, -7, 1, 8, 10, 12, 15, 17, 20 is bitonic, while 8, 5, 3, 2, 1, 7, 6 is not. Describe a divide-and-conquer algorithm that finds the minimum element in a bitonic array in O(logn) time. Hint: you can use the bitonic sequence in the example to describe your algorithm. (10 points) 2. Using the substitution method in the Lecture Week 3 slides as an example, show that the solution of T(n) = T(n - 1) + n is O(n^2). (5 points) 3. Using MAX-HEAPIFY example in the Lecture Week 3 slides as a model, illustrate the operation of MAX-HEAPIFY(A, 3) on the array A = [36, 19, 2, 17, 14, 11, 1, 5, 7, 12, 3, 8, 9, 0]. (5 points)

An organic Rankine cycle using R134a operates between a high and a low pressure. The pressure at states 1 and 4s and 4a is 6.6525bar = 665.25kPa. The pressure at states 2 and 3 is 26.323bar = 2632.3kPa. A heat exchanger is responsible for transferring energy to the cycle from the engine exhaust gases. The temperature of the exhaust gases entering the heat exchanger is 900K. The specific heat capacity of the exhaust gases can be taken to be 1.244 kJ/kgK. The mass flow rate of the exhaust gases is 1.2 times the mass flow rate of the refrigerant. Note that the $T-s$ diagram shows that the refrigerant is a saturated vapor at state 3. The isentropic efficiency of the scroll expander is 0.50. Heat transfer from the refrigerant in the condensing heat exchanger enables the refrigerant to become a saturated liquid at state 1. The refrigerant is cooled by a stream of air whose mass flow rate is 40 times higher than the mass flow rate of refrigerant. The restricted dead-state is $T_0 = 20^\circ C = 293.15K$ and $P_0 = 84.35kPa = 0.8435bar$. Draw the exergy wheel for this cycle giving $e_{f_1}$, $e_{f_2}$, $e_{f_3}$ and $e_{f_4}$. Energy Input from Exhaust Pump Exhaust Heat Exchanger Scroll Expander work input Heat Exchanger to surroundings work output net work Answer: check that everything balances.
