Answers

Answer 1

We'll use the loop function, if statement, and the compound operator for the code to modify an array's elements.

What is loop and compound operator?

Loop is function in all program language that iterates the statement under specific boundaries.

If statement is conditional statement that if the required condition are met then the program will execute.

Compound operator is combined two of operator to simplified code.

The code we will add to the given code is,

for (i = 0; i < dataPoints.length; ++i){

       if (dataPoints[i] < controlValue)

            dataPoints[i] *= 2;

}

This loop will running repeatedly until exceed dataPoints size.

The if statement will check dataPoints is less than controlValue or not, if yes then dataPoints will multiply it with compound operator *= 2.

Why the subnet above?

The appropriate host or subnet number and mask are used to determine the IP addresses in the subnet 15.119.44.128/26.

Note that the host formula is 2n -2, where n is the number of zeros on the place of the fourth octet and two is subtracted from the value signifying the network and broadcast addresses of the network address.

1. Design a DC power supply for the Fan which have a rating of 12V/1A

Answers

To design a DC power supply for a fan with a rating of 12V/1A, you would need to follow these steps:

1. Determine the power requirements: The fan has a rating of 12V/1A, which means it requires a voltage of 12V and a current of 1A to operate.

2. Choose a transformer: Start by selecting a transformer that can provide the desired output voltage of 12V. Look for a transformer with a suitable secondary voltage rating of 12V.

3. Select a rectifier: To convert the AC voltage from the transformer to DC voltage, you need a rectifier. A commonly used rectifier is a bridge rectifier, which converts AC to pulsating DC.

4. Add a smoothing capacitor: Connect a smoothing capacitor across the output of the rectifier to reduce the ripple voltage and obtain a more stable DC output.

5. Regulate the voltage: If necessary, add a voltage regulator to ensure a constant output voltage of 12V. A popular choice is a linear voltage regulator such as the LM7812, which regulates the voltage to a fixed 12V.

6. Include current limiting: To prevent excessive current draw and protect the fan, you can add a current-limiting circuit using a resistor or a current-limiting IC.

7. Assemble the circuit: Connect the transformer, rectifier, smoothing capacitor, voltage regulator, and current-limiting circuitry according to the chosen design.

8. Test and troubleshoot: Once the circuit is assembled, test it with appropriate load conditions to ensure it provides a stable 12V output at 1A. Troubleshoot any issues that may arise during testing.

Note: It is essential to consider safety precautions when designing and building a power supply. Ensure proper insulation, grounding, and protection against short circuits or overloads.

2. Consider a computer system called 3P2M in the following figure. The 3P2M system consists of three processors and two shared memories communicating over a shared bus, as shown in the following Figure. The system is operational as long as at least two processors can communicate with at least one of the two memories over the bus.

a) Construct the fault tree model of this system
b) Find all the minimal cut sets
c) Assume all the components fail exponentially with the following failure rates: processors (P1, P2, P3): 0.0001/hour; memories (M1, M2): 0.0001/hour; bus: 0.000001/hour. Find the system reliability at mission time t=100 hours.

Answers

1. The probability of the component surviving 200 hours is 0.9608 and still functioning after 400 hours is 0.8862.

2. Assuming all the components fail exponentially, the system's reliability at mission time t = 100 hours is 0.999985.

How to calculate system's reliability?

1) To determine the probability that the component survives 200 hours, we need to use the survival function, which is the complement of the cumulative distribution function (CDF).

The CDF gives the probability that the component fails before or at time t, and is given by:

F(t) = 1 - e^(-∫z(u)du), where the integral is taken from 0 to t.

In this case, the failure rate function is z(t) = 2.0 × 10⁻⁶ t/hour for t > 0, so the integral becomes:

∫z(u)du = ∫2.0 × 10⁻⁶ u du = 10⁻⁶ u² + C,

where C is a constant of integration. Evaluating this integral from 0 to 200 hours:

∫0²⁰⁰ z(u)du = 10⁻⁶ (200)² = 0.04

So the CDF at 200 hours is:

F(200) = 1 - e^(-0.04) ≈ 0.0392

Therefore, the probability that the component survives 200 hours is:

P(T > 200) = 1 - F(200) ≈ 0.9608

To determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, we need to use the conditional probability formula:

P(T > 400 | T > 200) = P(T > 400 and T > 200) / P(T > 200)

The numerator represents the probability that the component survives beyond 400 hours given that it has already survived 200 hours, while the denominator represents the probability that the component survives beyond 200 hours.

The joint probability of surviving beyond 400 and 200 hours is:

P(T > 400 and T > 200) = P(T > 400)

since if the component survives beyond 400 hours, it necessarily also survives beyond 200 hours.

The probability of surviving beyond 400 hours is:

P(T > 400) = 1 - F(400) = 1 - (1 - e^(-∫z(u)du)) = e^(-∫z(u)du)

Using the same integral as before:

∫0⁴⁰⁰ z(u)du = 10⁻⁶ (400)² = 0.16

So:

P(T > 400) = e^(-0.16) ≈ 0.8521

The probability of surviving beyond 200 hours was found to be approximately 0.9608 in part (1).

Therefore, the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours is:

P(T > 400 | T > 200) = P(T > 400 and T > 200) / P(T > 200)

= P(T > 400) / P(T > 200)

= (e^(-0.16)) / (0.9608)

≈ 0.8862

2) a) Fault tree model of the 3P2M system:

                  1

           /      |      \

        P1     P2     P3

         |         |         |

        1|        1|        1|

         |         |         |

         B       B       B

         |         |         |

        1|        1|        1|

         |         |         |

        M1     M2     M1

          \      /         /

            \  /       /

             1     1

where P1, P2, and P3 are the processors, M1 and M2 are the memories, B is the bus, and the numbers above the components represent their probabilities of not failing.

b) Minimal cut sets:

{P1, P2, M1}

{P1, P2, M2}

{P1, P3, M1}

{P1, P3, M2}

{P2, P3, M1}

{P2, P3, M2}

c) To calculate the system reliability, we can use the following formula:

R = e^(-λt)

where R is the system reliability, λ is the failure rate, and t is the mission time.

Using this formula, we can calculate the reliability of each component:

Processor: Rp = e^(-0.0001 × 100) = 0.9048

Memory: Rm = e^(-0.0001 × 100) = 0.9048

Bus: Rb = e^(-0.000001 × 100) = 0.9999

Next, use the minimal cut sets to calculate the system reliability. The minimal cut sets are:

{P1, M1, M2}

{P2, M1, M2}

{P3, M1, M2}

{P1, P2, M1}

{P1, P2, M2}

{P1, P3, M1}

{P1, P3, M2}

{P2, P3, M1}

{P2, P3, M2}

The system reliability can be calculated using the following formula:

Rsys = 1 - Σ(Ri × Π(Rj))

where Ri is the reliability of the i-th minimal cut set, and Π(Rj) is the product of the reliabilities of all components in the j-th minimal cut set.

Using this formula, calculate the system reliability:

Rsys = 1 - [(0.0952 × 0.0952 × 0.0952) + (0.0952 × 0.0952 × 0.0952) + (0.0952 × 0.0952 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952) + (0.9048 × 0.9048 × 0.0952)]

Rsys = 0.999985

Therefore, the system reliability at mission time t=100 hours is approximately 0.999985.
