Suppose you have one machine and a set of n tasks a1; a2; : : : ; an. each task aj has a processing time pj , a pro t pj , and a deadline dj . if you complete a task aj by deadline dj , you receive a pro t pj (otherwise, you receive no pro t). you wish to nd a schedule that completes all the tasks and derives the maximum pro t. (a) state the decision version of this problem. (b) show that it is np-complete by reducing the knapsack problem to it. (c) give a polynomial-time algorithm for the decision problem, assuming that all processing times are integers from 1 to n

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
