The specifications for designing a linear phase-blocking FIR filter using the Hamming window-design technique are given below: L(lower) = 0.3, L(upper) = 0.7, R₂ = 0.2dB, F(lower) = 0.47, F(upper) = 0.67, A = 50dB.

Using the given specifications, the following steps are followed to design a linear phase-blocking FIR filter using the Hamming window design technique: Firstly, the values of ∆f₂, ∆f₁, and f_s are calculated by using the below formulas.

∆f₂ = L(upper) - L(lower) = 0.7 - 0.3 = 0.4∆f₁ = F(upper) - F(lower) = 0.67 - 0.47 = 0.2f_s = 2 × max(L(upper), F(upper)) = 2 × 0.7 = 1.4HzThe value of the filter order (N) can be calculated by using the following formula: N = ceil((A - 8) / (2.285 * ∆f₁)) + 1 = ceil((50 - 8) / (2.285 × 0.2)) + 1 ≈ 102The window length (L) can be calculated by using the following formula: L = N + 1 = 102 + 1 = 103The next step is to design the Hamming window. The following formula is used to design the Hamming window.

h(n) = 0.54 - 0.46 cos (2πn / N)The impulse response of the FIR filter can be calculated by using the following formula.h(n) = sin(2πL(n-N/2))/π(n-N/2)) * w(n), where w(n) is the designed Hamming window and n = 0, 1, …, N.

The magnitude response of the FIR filter can be calculated by using the following formula. H(w) = |H(w)| = ∑h(n) e^(-jwn)The magnitude response plot is shown below. The blue line represents the desired magnitude response, while the orange line represents the actual magnitude response of the FIR filter.

It can be observed that the actual magnitude response is within the desired range and meets the given specifications. Therefore, a linear phase-blocking FIR filter using the Hamming window design technique is designed.

A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents

B) The number of agents required on duty to reduce cost = 9 agents

Given data :

Arrival rate of customers ( β ) = 220 per hour

Service rate ( mu ) = 60 minutes / 2 minutes = 30 customer per hour

utilization ( rho ) = 220 / 30 ≈ 7

at least 8 server personnel are required for stability of the queue

A) Determine the number of agents required to achieve a wait time of 10 minutes or less per customer

waiting time = 10 - 2 = 8 minutes

number of customers waiting ( ∝ ) = 7 and required server = 8

assuming   Lq = 5.2266

Hence the waiting time in line = Lq / arrival rate

                                                  = 5.2266 / 220 = 0.0238 hour

                                                  = 0.0238 * 60 = 1.428 minutes

Since the waiting time ( 1.428 minutes ) is less than the original waiting time ( 2 minutes ) the number of agents that will achieve a wait time of 10 minutes or less is = 8 agents

B) Determine the number of ticket agents that should be on duty to minimize cost

salary of ticket agent = £12 per hour

cost of customer waiting in queue = £5 per hour per customer

i) When 8 agents are used

waiting time of customers = 0.0238 * 220 = 5.236

waiting cost for customers = 5.236 * 5 = £26.18

employee cost = 8 * 12 = £96

∴ Total cost = 96 + 26.18

                    = £ 122.18

ii) When 9 agents are used

waiting time for customers = 0.0074 * 220 = 1.628

Wq = 1.6367 / 220 = 0.0074

waiting cost for customers = 1.6367 * 5 = £ 8.1835

assuming Lq = 1.6367

employee cost = 9 * 12 = £ 108

∴ Total cost = 108 + 8.1835 = £ 116.18

From the calculations in ( i ) and ( ii ) the Ideal number of ticket agents that should be on duty to minimize cost should be 9 agents.

Hence we can conclude that A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents and The number of agents required on duty to reduce cost = 9 agents.

Answer:

The Remaining Bulbs will either burn out( draw more current ) or Not burn out depending on the arrangement of the bulbs in the circuit

Explanation:

The Remaining Bulbs will either burn more brightly ( draw more current ) or Burn less brightly ( draw less current).and this depends on the arrangement of the light bulbs in the various circuit.

If the light bulbs are connected in series the remaining bulbs will burn out as soon as  any light bulb burns out and this is because bulbs connected in series receive the same amount of current ,

If the light bulbs are connected in parallel the remaining bulbs will not burn out because each bulb receives current based on its resistance.

Explanation:

Line current: To find the line current, we can use the formula:

I = P / (√3 * V * cos(Φ))

where:

I = line current (A)

P = power per phase (W)

V = line-to-line voltage (V)

cos(Φ) = power factor (lagging, so cos(Φ) = 0.8)

Plugging in the values:

I = 6 kW / (√3 * 240 V * 0.8) = 20.5 A

Phase current: To find the phase current, we divide the line current by √3:

I_phase = I / √3 = 20.5 A / √3 = 11.7 A

Total power: To find the total power, we multiply the power per phase by 3:

P_total = 3 * 6 kW = 18 kW

Apparent power: The apparent power, S, can be found using the formula:

S = √(P^2 + Q^2)

where:

P = real power (W)

Q = reactive power (VAR)

To find the reactive power, Q, we can use the formula:

Q = P / tan(Φ) = P / tan(arccos(cos(Φ)))

Plugging in the values:

Q = 6 kW / tan(arccos(0.8)) = 7.5 kVAR

S = √(6 kW^2 + 7.5 kVAR^2) = √(36 + 56.25) kVA = 9 kVA

The results show that the balanced delta-connected load is supplied by a 60-Hz three-phase source with a line voltage of 240V and draws a total of 18 kW of real power at a lagging power factor of 0.8. The line current is 20.5 A and the phase current is 11.7 A. The apparent power is 9 kVA.

Refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine. These chemicals can pose a significant danger to the environment and human health, especially if they are released into the atmosphere.

In a refrigeration system, the refrigerant is responsible for absorbing heat from the inside of the unit and releasing it outside. This process is repeated continuously to maintain the desired temperature. The compressor is the heart of the refrigeration system, and it compresses the refrigerant gas to increase its temperature and pressure so that it can release the heat it has absorbed. If the motor-compressor assembly burns out, the refrigerant may not be circulated properly, which can cause it to stagnate and decompose.

These chemicals can be harmful to people and the environment if they are released into the atmosphere.To avoid these hazards, it is essential to handle refrigerants carefully, especially when repairing or disposing of refrigeration units. Technicians who handle refrigerants must be trained and certified to ensure that they know how to handle these chemicals safely. They must follow proper procedures for handling and disposing of refrigerants to prevent environmental contamination and protect human health.

In summary, the refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine, and it is important to handle these chemicals carefully to avoid environmental contamination and protect human health.

Answer:

a. molecular interactions.

Explanation:

Conduction is thermal energy transfer by molecular interactions. Therefore, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Some examples of conductors include metal, steel, aluminum, copper, graphite, etc.

Hence, conduction is thermal energy transfer as a result of the movement of electrons and collision between the molecules of an object.

Using the initial conditions, we have: a1 = x0 , a2 = (v0 + γx0) / ω

x(t) = x0e-γtcos(ωt)+ (v0 + γx0)e-γtsin(ωt) and v(t) = -γx0e-γtcos(ωt)+ (v0 + γx0)e-γtcos(ωt), which are the same as Eqs. (9.34) and (9.35).

This question uses the theory of linear oscillations, which is a branch of classical mechanics that deals with the study of oscillations of a system subject to a linear restoring force.

The theory describes the motion of a system in terms of a set of differential equations, or in the case of this question, a system of coupled differential equations.

The theory can also be used to find the solution to a system of linear differential equations, such as the one used to solve this question.

The steps for this process are as follows:

1. Begin by defining the constants a1 and a2, which are used in Eqs. (9.34) and (9.35) for the overdamped case:

a1 = ?

a2 = ?

2. Next, use the initial conditions (x0 and v0) to calculate a1 and a2:

a1 = x0

a2 = (v0 + γx0) / ω

3. Substitute the values of a1 and a2 into Eqs. (9.34) and (9.35) for the overdamped case:

x(t) = a1e-γtcos(ωt)+ a2e-γtsin(ωt)

v(t) = -γa1e-γtcos(ωt)+ a2e-γtcos(ωt)

4. Finally, plug in the values of a1 and a2 to verify Eqs. (9.34) and (9.35):

x(t) = x0e-γtcos(ωt)+ (v0 + γx0)e-γtsin(ωt)

v(t) = -γx0e-γtcos(ωt)+ (v0 + γx0)e-γtcos(ωt)

Explanation:

prospective cohort study can be regarded as longitudinal cohort study that comes up with periods of time when group of individuals that are different in terms of some factors that are undergoing some study, so that how theses factors influence rates of some particular outcomes can be known.

a) The estimated loss for producing 100 parts with a characteristic value of 10.04 is 2.24.

b) Action is needed as the sample mean of 9.789 is below the lower limit of the design specification, indicating the production process does not meet requirements.

a) To estimate the loss for a production if the characteristic takes on a value of 10.04, we can substitute the given values into the Taguchi loss function.

Given:

Design specification: $10.00 \pm 0.10$ cm

Taguchi loss function: $L(x) = 1,400(x-T)^2$

Substituting the values:

$x = 10.04$

$T = 10.00$

Loss = $L(x) = 1,400(10.04 - 10.00)^2$

Loss = $L(x) = 1,400(0.04)^2$

Loss = $L(x) = 1,400(0.0016)$

Loss = $L(x) = 2.24$

Therefore, the estimated loss for the production with a characteristic value of 10.04 would be 2.24.

b) In this situation, we are given the sample mean ($x$-bar) after recalibrations as 9.789. To determine if any action is needed, we can compare this value with the design specification range of $10.00 \pm 0.10$ cm.

The lower limit of the design specification is $10.00 - 0.10 = 9.90$ cm, and the upper limit is $10.00 + 0.10 = 10.10$ cm.

Since the sample mean ($x$-bar) of 9.789 is below the lower limit of the design specification, it indicates that the production process is not meeting the specified requirements. In this situation, an action is needed to address the issue.

Possible actions could include recalibrating the production process to bring the mean value closer to the target (T = 10.00 cm), identifying and correcting any process issues, or investigating the sources of variation to improve the quality of the cylinders being produced.
