Throwaway prototyping is effective for eliciting the 'true' user requirements, while prototyping as an evolutionary development method allows for iterative refinement and continuous improvement.

Throwaway prototyping involves creating a prototype quickly and then discarding it after gathering user feedback. This approach allows stakeholders to experience and interact with a tangible representation of the system early in the development process. By using the throwaway prototype as a communication tool, the development team can better understand the user requirements and make adjustments based on user feedback. It helps in discovering and refining the 'true' user requirements before proceeding to the actual development phase.

On the other hand, prototyping as an evolutionary development method focuses on building an initial prototype and then incrementally improving it through multiple iterations. This approach allows for continuous feedback and refinement, enabling the system to evolve gradually. As the prototype is refined and enhanced with each iteration, it becomes more aligned with the actual requirements and user expectations.

Both approaches have their merits. Throwaway prototyping is effective in the early stages of a project when there is a need to explore and validate user requirements. It allows for rapid feedback and helps uncover any misunderstandings or missing requirements. On the other hand, prototyping as an evolutionary development method is beneficial when the requirements are not fully known or may change over time. It provides flexibility and the ability to adapt and refine the system through iterative cycles.

In conclusion, throwaway prototyping is valuable for eliciting the 'true' user requirements, while prototyping as an evolutionary development method enables continuous improvement and adaptation. The choice between these approaches depends on the specific project context, time constraints, and the level of clarity in user requirements.

The control of a DC motor with the aid of PID control is of utmost importance in various engineering applications. The first step in developing a control system for a DC motor with the aid of PID control is to create a model of the system to be regulated. The control problem of a DC motor with the use of PID control is examined in the following lines.

The following are the system parameters:

[tex]Jm = 1.13 x 10^-2 kgm^2, b = 1.2 x 10^-3 Nms,[/tex]

[tex]Ke = 0.5 V/rad/sec, and Kt = 0.5 Nm/A.[/tex]

The armature circuit resistance and inductance are both negligible. The DC motor's transfer function can be derived from the equations of motion and Kirchhoff's voltage law. It is possible to derive the transfer function of the DC motor with the aid of Laplace transformation.

The transfer function of the DC motor is given by:

[tex]T(s) = 0.5/[(1.13 x 10^-2)s^2 + (1.2 x 10^-3)s + 0.5][/tex]

The control system of a DC motor with PID control can now be created based on this transfer function. To build a PID control system, the controller parameters Kp, Ki, and Kd must be selected. Kp, Ki, and Kd are the proportional, integral, and derivative coefficients, respectively.

The transfer function of the PID control system can be derived from the transfer function of the DC motor by adding the controller's transfer function. The transfer function of the PID control system is:

[tex]T(s) = Kp + Ki/s + Kd s[/tex]

This equation must be solved in order to get Kp, Ki, and Kd, the PID coefficients. To improve the DC motor control, the PID coefficients must be adjusted appropriately.

Apply the S-Boxes: [1011] [0110] → 11 6.

Apply the Permutation (P): 11 6 → 0101.

Repeat the above steps for rounds 3 to 16, using the same key.

c. After the 16th round, apply the Final Permutation (FP) to the result: 00011010 → 01101000.

The resulting decrypted 8-bit plaintext is 01101000, which corresponds to the ASCII character 'h'.

Therefore, the plaintext represented by the received ciphertext 11000111, assuming CBC mode and using the DES encryption algorithm with the given key, is 'h'.

The function "SortedSublist(A, B)" checks if every element in list A is present in list B in the same order. It returns True if this condition is met, and False otherwise.

To implement the "SortedSublist(A, B)" function, you need to iterate through both lists simultaneously. Compare each element in list A to the corresponding element in list B, ensuring that the order is maintained.

You can use a loop to iterate through the elements of both lists. At each iteration, compare the current elements from both lists. If they are equal, move to the next element in both lists. If they are not equal, continue comparing the next element in list A with the current element in list B.

If you reach the end of list A and have successfully matched all elements with their corresponding elements in list B, the function returns True. Otherwise, if any element in list A is not found in list B or the order is not maintained, the function returns False.

The function assumes that the input lists, A and B, are sorted and contain unique integer values.
