Consider a system with closed-loop transfer function. By using a Routh-Hurwitz stability criterion, determine K in order to make the system to operate in a stable condition. K H(s) = s(s² + s + 1)(s+ 2) + K

The Vin(t) has an amplitude range of 0 to 5 and 0 to 2.5 for a period of 1 millisecond (ms). The time increments of 10 microseconds (us) must be plotted between the values of 0 to 1ms. Consequently, there are 100,000 data points in 1ms, with 10us intervals between each data point.

Part 1 Recap and Analysis Part 1 was concerned with the following circuit as shown below.

Vin (t) is fed into the high-pass filter, and Vout (t) is produced at the other end. The output voltage of this high-pass filter was obtained and examined in the frequency domain. To begin, the following variables were used:

RC = 1 x 10-4 s, R = 1 x 103 Ω, and C = 1 x 10-7 F.

Then, using the function h(f), the frequency response was defined as follows: H (f) = h (f)/h (0) = (RCf)/(1 + RCf). The magnitude response, H (f), and phase response, (f), were derived from this expression. Using MATLAB, both the phase and magnitude response were plotted against the frequency of the input signal.

The cutoff frequency (fc) was determined to be 1000 Hz, and the bandwidth (B) was calculated to be 1 kHz. The filter is considered a high-pass filter since it has a 1st order response and is capable of passing signals at frequencies above its cutoff frequency while blocking signals below that frequency. The low frequencies and high frequencies are referred to as noise and signal, respectively.

Vin(t) Graphical RepresentationThe first step is to plot the function Vin(t) mathematically. Vout(t) is defined by the transfer function H(f), which is derived from Vin(t).

The first step is to plot Vin(t), which is given by:

Vin(t) = 5.0sin(wt + 0) + 1.0sin(wt + 0) + 2.5sin(w3t + 0) On the MATLAB Command Window, enter the following code: t = 0:0.00001:0.001; Vin = 5*sin(8000*pi*t)+ 1*sin(29000*pi*t)+ 2.5*sin(242000*pi*t); plot(t,Vin) xlabel('time (s)') ylabel('Amplitude (V)') title('Vin(t) Plot')

Output: The resultant Vin(t) is graphed below.

The initial part oscillates between 0 and 5, and the last section between 0 and 2.5. In other words, the function Vin(t) is made up of three components with different amplitudes and frequencies.

The EPR valve in the suction line at the evaporator outlet modulates the refrigerant vapor flow to the compressor, prevents the boiling point in the evaporator from dropping too low, and operates in conjunction with a TX valve to regulate the refrigerant flow and maintain proper system performance.

The EPR (Evaporator Pressure Regulator) valve is installed in the suction line at the evaporator outlet and serves multiple functions. It modulates the refrigerant vapor flow to the compressor, prevents the boiling point in the evaporator from dropping below a preset point, and operates like an AX (Automatic Expansion) valve when used in conjunction with a TX (Thermal Expansion) valve. The EPR valve plays a crucial role in regulating the pressure and temperature within the evaporator. By modulating the refrigerant vapor flow to the compressor, it helps maintain optimal system performance. This modulation ensures that the compressor receives a consistent and controlled flow of refrigerant, preventing it from being overloaded or underutilized. Additionally, the EPR valve acts as a safeguard against the evaporator's boiling point dropping below a predetermined threshold. This is important because if the boiling point decreases too much, it may lead to frost formation on the evaporator, reduced heat transfer efficiency, and potential damage to the compressor. When used alongside a TX valve, the EPR valve operates in a manner similar to an AX valve. An AX valve is an automatic expansion valve that regulates the refrigerant flow into the evaporator based on superheat measurements. By controlling the suction pressure, the EPR valve ensures proper superheat levels and assists in maintaining the optimal functioning of the TX valve.

To determine the blocks that must be read from and written to the disk for each operation in different disk block allocation schemes, we need to consider the characteristics of each scheme and analyze the given sequence of operations.

The disk block allocation schemes and their impact on the required read and write operations. In the contiguous allocation scheme, where files occupy consecutive blocks, the read operation for block D would require accessing block D directly. Similarly, the read operation for block F would require accessing block F directly. The delete operation of block E would entail modifying the file control information to skip block E. Finally, inserting a new block C' between C and D would involve shifting subsequent blocks and updating the file control information accordingly.

In the linked allocation scheme, where blocks are linked together via pointers, the read operation for block D would involve traversing the linked blocks until reaching block D. Similarly, the read operation for block F would involve traversing the linked blocks until reaching block F. The delete operation of block E would entail updating the pointers to bypass block E. Inserting a new block C' would require finding a free block and updating the pointers accordingly

Using the File Allocation Table (FAT) scheme, the read operation for block D would involve checking the FAT to find the location of block D. Similarly, the read operation for block F would involve checking the FAT to find the location of block F. The delete operation of block E would require updating the FAT to mark block E as free. Inserting a new block C' would involve finding a free block, updating the FAT to allocate it, and adjusting the pointers accordingly.

In the indexed allocation scheme, where each file has an index block containing pointers to its data blocks, the read operation for block D would involve accessing the index block to find the location of block D. Similarly, the read operation for block F would involve accessing the index block to find the location of block F. The delete operation of block E would require updating the index block to remove the pointer to block E. Inserting a new block C' would involve finding a free block, updating the index block to include a pointer to the new block, and adjusting the pointers accordingly.

This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.

The force exerted at the large piston will be double in magnitude in comparison with the force applied at the smaller piston.

We know, according to the pascal's law,

The pressure applied at any point in the incompressible fluid is equal in magnitude at each and every point.

So,

P = Force/Area

Where P is pressure,

If pressure is same, then we can write,

F₁/A₁ = F₂/A₂

Where,

F₁ is the force applied at the small piston,

A₁ is the area of the smaller piston,

F₂ is the force at the larger piston,

A₂ is the area of the larger piston,

It is also given that, area if the larger piston is two times the area of the smaller piston so,

A₂ = 2A₁

So, putting the values we get,

F₂/F₁ = 2

So, F₂ = 2F₁

It means that the force exerted by the larger piston will be double in magnitude.

Therefore, In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.

According to the Federal Aviation Administration (FAA) Instrument Procedures Handbook, the minimum descent altitude (MDA) for a straight-in localizer/distance measuring equipment (LOC/DME) runway 21 approach at Portland International Airport in a category B airplane would be 1,120 feet above mean sea level (MSL). The visibility requirement for this approach would be 1 statute mile (SM). Therefore, the correct answer to your question is: b. 1,120 ft. MSL; visibility 1 sm.

It's important to note that the MDA and visibility requirements for an approach can vary depending on the specific approach being flown and the equipment available at the airport. It's also worth mentioning that the MDA and visibility requirements must be met to fly the approach. If the actual conditions at the airport are below these minimums, the approach cannot be flown, and the pilot must either execute a missed approach or proceed to an alternate airport.

The minimum descent altitude (MDA) is the lowest altitude that an aircraft is allowed to descend to during an instrument approach. It is typically expressed in feet above mean sea level (MSL) and is established to provide the pilot with an apparent visual reference of the approach path and the surrounding terrain. The MDA is determined based on the type of approach being flown and the equipment available at the airport.

The MDA is not a decision altitude (DA), which is the altitude at which the pilot must decide to either land or execute a missed approach. The DA is typically higher than the MDA and is based on the height of obstacles in the approach path. It's important to note that the MDA is a minimum altitude, and the pilot is not required to descend to the MDA unless it is safe to do so. If the pilot cannot see the runway or the required visual references at the MDA, a missed approach must be executed. In other words, the MDA is the minimum altitude that must be maintained during an instrument approach unless the pilot can see the runway or the required visual references, in which case the pilot may continue the approach and land.
