Can using a separate mutex for each page in a buffer pool avoid deadlocks?  

In a slotted page structure, what happens when an update increases the size of a tuple beyond its original allocated space (assume that the updated tuple is still smaller than the slotted page)?  

2Q buffer replacement policy is managing a 3-frame buffer pool. The current state of the queues is: LRU Queue (ordered least recently used first → most recently used last): {1, 2} FIFO Queue (ordered oldest inserted first → newest inserted last): {9} The next page reference is 2.   What will be the new state of the queues after this access?  

std::rand() % user_ids.size()   What is the possible output range of the following C++ expression?  

Problem 1. (15 points total) What are the different types of faults that can occur in a power system?    Problem 2. (15 points total) Describe any three applications of a phasor measurement unit (PMU).    Problem 3. (20 points total) Suppose that there is a three-bus system. The voltage phasors of the three buses are V1 = 1∠0° V, V2 = 2∠30° V, and V3 = 3∠60° V. The network has a triangular structure (i.e., all three buses are connected to each other), and all the line impedances are equal to 1 + j Ω. What is the phasor representation of the three current phasors in Cartesian coordinates?
