Question

We have 4 periodical processes II₁, I₂, I3 and П4, that process a video. We know their
periods P, and their running times C; (in milliseconds). For:
(a) the rate monotonic scheduling (RMS) algorithm and
(b) the earliest deadline first (EDF) algorithm
draw diagrams that displays the schedule for those processes for a period of 150 ms. The
times are the following:
Process PC₁
II₁
45 10
II₂
40 10
II 3
35 5
II4 50 10
In the case of equal priorities the process that is already running has the priority. If this
is not the case then take the process with the lowest ID. Does any of the above algorithms
fail?

thermostat, which will turn the heat on when the room temperature drops h degrees below its set point, Ts, and cuts heat off at a temperature h degrees higher than Ts . The system heats at a constant rate Q (thermal units per time unit), and the volume of the room is V, so, if the room were perfectly insulated, the heating system would raise the temperature of the room at the rate KVQ (degrees per time unit), where K is a constant of proportionality giving the change in temperature per thermal unit per unit volume. However, there is a heat loss to the outside that is proportional to the difference in temperature between the room and the outside. Using the modified Euler method, write a FORTRAN program to simulate this system, if the room temperature at time is T(t), T(0) = To, and the outside temperature, Tout' is given by: Case (1) : Tout is constant < Ts Case (2) : Tout = A sin(wt + 4)| , %3D reflecting daily cycles.

A performance venue hosts many concerts a year. Performers perform several times a year for the concerts. Each concert has one or more performers and has a name and a specified seating arrangement. A concert is held in one (and only one) of several concert halls, each of which has a room number and the number of seats. Each concert generates revenues from the sales of tickets. Assume that the price of the ticket is the same for the same concert, but different prices for different concerts.Identify several attributes and a key field for each entity. Represent this situation of concerts and performers with an E-R diagram
The liquid-liquid extraction process carried out at the Electrochemical Materials Laboratory involves the extraction of nickel (Ni) from the liquid phase into an organic phase.

Ni phase cair, a (gr/l) 2 2,5 3 Ni phase organik, g (gr/l) 8,57 10 12 Assume that a is the amount of Ni in the liquid phase, and g is the amount of Ni in the organic phase. Quadratic interpolation is used to estimate the value of g, which is given by the following formula: g = x1a? + x2a + x3 a. Find three simultaneous equations based on the data given by the experimental results. b. Use the Gauss Elimination method to get the values of x1, x2 and x3 and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase. c. Use the LU Decomposition method to get the values of x1, x2 and x3. and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase.
