A) (1 pt) load the file steam. txt. this would create a 3 column matrix with the name steam that has all the data in the file. b) (3 pts) assign column 1, 2, and 3 of steam to variables t, vf, and vg, respectively. c) (3 pts) use vf and vg in equation (1) to create 3 more column vectors, which will be the specific volume at x = 0.25, 0.5, and 0.75. d) (2 pts) now your program must create a matrix steam_mod where the 1st column is the temperature, as before, while columns 2 to 6 will be the specific volume at x = 0, 0.25, 0.5, 0.75 and 1, respectively. e) (1 pt) save steam_mod in another ascii file steam_mod. dat. f) (2 pts) using the disp() function with format short g, display the 1st 30 rows of steam_mod as t v(x=0) v(x=0.25) v(x=0.5) v(x=0.75) v(x=1)

Write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removedproblems 1.1 write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removed 20 power system relaying from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0+j0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the stub-end fault í• figure 1.16 problem 1.1 system data for figure 1.16 from to positive sequence 0.0+j0.1 0.05j0.15 0.04 j0.2 0.01 jo.i 0.015 + j0.15 0.01 j0.19 0.01 +j0.19 0.03+j0.1 0.0+j0.08 6 6 6 from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0 + j 0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b1, and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the “stub-end” fault.

3. bob is arguing that if you use output feedback (ofb) mode twice in a row to encrypt a long message, m, using the same key each time, it will be more secure. explain why bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).
