When the process is in control but does not meet specification which type of error is it?

Answers

When the process is in control but does not meet specification, it is referred to as a special cause error.

What is the term for a process in control but not meeting specification?

In statistical process control, a process is considered to be in control when it operates within the defined limits and shows only random variations. However, when a process is in control but does not meet the desired specifications, it indicates the presence of a special cause error.

Special cause errors are attributed to specific factors or events that cause the process to deviate from the expected outcome. These errors are typically unpredictable and require investigation and corrective action to bring the process back within the desired specifications.

The acceleration of a particle is defined by the relation a = 9 − 3t2, where a and t are expressed in ft/s2 and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 5 ft. Determine (a) the time when the velocity is again zero, (b) the position and velocity when t = 4 s, (c) the total distance travelled by the particle from t = 0 to t = 4 s.

Answers

(a) To find the time when the velocity is again zero, we set the velocity equal to 0 and solve for t:

0 = v0 + at = 9t - 3t^3

Solving for t, we find that t = ±1.

(b) To find the position and velocity when t = 4 s, we first need to find the velocity equation by integrating the acceleration equation:

v = ∫a = ∫(9 - 3t^2)dt = 9t - t^3 + C

Using the initial condition v(0) = 0, we find C = 0 and

v(t) = 9t - t^3

Next, we integrate v(t) to find the position equation:

x = ∫v = ∫(9t - t^3)dt = 3t^2 - t^4 + C

Using the initial condition x(0) = 5, we find C = 5 and

x(t) = 3t^2 - t^4 + 5

Evaluating x(t) and v(t) at t = 4 s, we have:

x(4) = 3(4^2) - 4^4 + 5 = 51

v(4) = 9(4) - 4^3 = -36

(c) To find the total distance travelled by the particle from t = 0 to t = 4 s, we need to find the distance between the initial and final positions:

d = x(4) - x(0) = 51 - 5 = 46 ft

So the total distance travelled by the particle from t = 0 to t = 4 s is 46 ft.

Answers

Option A holds the correct answer. Because the statement given in option A truly reflects the radial load and axial load.

When the load pressure is perpendicular to the axis of the shaft, a radial load is applied and when the load pressure is parallel to the axis of the shaft, an axial load is applied. In other words, the radial load is applied when the pressure from the load is 'perpendicular to the axis of the shaft'. In contrast, the axial load is applied when the pressure from the load is 'parallel to the axis of the shaft'.

Unfortunately, when using turtle graphics, there is no built-in way to store and call on functions. This means that each time you want to use a particular set of commands, you have to rewrite them in your code.

However, there are some workarounds that you can use to achieve similar functionality. One option is to define a list of commands as a variable, and then iterate through that list using a for loop. Another option is to define a custom function that takes in parameters and then executes a set of turtle commands based on those parameters.

While these solutions may not be as elegant as having built-in function storage and calling, they can still be effective for simplifying your code and reducing repetition.

Discuss the exciton roles in silicon solar cell

Answers

Excitons play a crucial role in silicon solar cells and are involved in several processes that contribute to the generation of electricity. Here are some key roles of excitons in silicon solar cells:

1. Absorption of Photons: When photons from sunlight strike the silicon material of a solar cell, they can be absorbed by silicon atoms, promoting an electron from the valence band to the conduction band. This process creates an exciton—a bound electron-hole pair.

2. Exciton Diffusion: After absorption, excitons can diffuse through the silicon material, moving towards the region of the solar cell where charge separation occurs. This diffusion process allows excitons to reach the vicinity of the p-n junction, where the separation of charges takes place.

3. Exciton Dissociation: At the p-n junction of a silicon solar cell, excitons can undergo dissociation. The electric field created by the junction separates the electron and hole of the exciton, allowing them to move freely in opposite directions as charge carriers.

4. Electron and Hole Transport: Once the exciton is dissociated, the free electron and hole can move independently within the solar cell. They are transported through the silicon material to the respective electrodes, creating an electric current that can be harnessed for external use.

5. Recombination: Excitons can also undergo recombination, where the electron and hole recombine, releasing energy in the form of light or heat. Recombination is undesirable in solar cells as it reduces the overall efficiency of the device.

To enhance the efficiency of silicon solar cells, various strategies are employed to minimize exciton recombination and improve exciton dissociation and charge carrier transport. These include the use of anti-reflection coatings, surface passivation techniques, and optimization of the device structure.

Overall, excitons play a vital role in the absorption and conversion of sunlight into electrical energy in silicon solar cells. Understanding and controlling exciton dynamics are essential for improving the performance of solar cells and advancing the field of photovoltaics.

Example 2: a second class highway, slope change point survey point k2+360.00, elevation is 780m, i+=+6%,
i2=-4%, the radius of vertical curve is 2500m.
(1) calculate geometric element of vertical curve.
(2) design elevation for k2+300.00 and k2+400.

Answers

As per the details given, the design elevation for k2+300.00 is approximately 942.29 m and for k2+400.00 is approximately 941.84 m.

To calculate the geometric elements of the vertical curve, we'll use the given information:

(1) Geometric Elements of Vertical Curve:

(a) Elevation at the PVC (Point of Vertical Curvature):

Elevation at PVC (E_PVC) = Elevation at k2+360.00 = 780 m

(b) Elevation at the PVI

Elevation at PVI (E_PVI) = Elevation at PVC + (R * i1/100)

E_PVI = 780 + (2500 * 6/100)

E_PVI = 930 m

(c) Elevation at the PVT:

Elevation at PVT (E_PVT) = Elevation at PVI + (R * (i2 - i1)/100)

E_PVT = 930 + (2500 * (-4 - 6)/100)

E_PVT = 730 m

(2) Design Elevation for k2+300.00 and k2+400.00:

Elevation (E) = E_PVI + [(\(R^2\) / 2) * ((1 / X) - (1 / (L - X)))] + [(i1 / 100) * X * (L - X)]

(a) Design Elevation for k2+300.00:

Distance from PVI to k2+300.00 = 300.00 - 360.00 = -60.00 m

Elevation at k2+300.00:

E = E_PVI + [(\(R^2\) / 2) * ((1 / X) - (1 / (L - X)))] + [(i1 / 100) * X * (L - X)]

E = 930 + [(\(2500^2\) / 2) * ((1 / -60) - (1 / (2500 - (-60))))] + [(6 / 100) * (-60) * (2500 - (-60))]

E ≈ 942.29 m

(b) Design Elevation for k2+400.00:

Distance from PVI to k2+400.00 = 400.00 - 360.00 = 40.00 m

Elevation at k2+400.00:

E = E_PVI + [(\(R^2\) / 2) * ((1 / X) - (1 / (L - X)))] + [(i1 / 100) * X * (L - X)]

E = 930 + [(\(2500^2\) / 2) * ((1 / 40) - (1 / (2500 - 40)))] + [(6 / 100) * 40 * (2500 - 40)]

E ≈ 941.84 m

Therefore, the design elevation for k2+300.00 is approximately 942.29 m and for k2+400.00 is approximately 941.84 m.

A structural component is fabricated from an alloy that has a plane strain fracture toughness of 45 MPam.

What is the maximum allowable surface crack length (in mm) without fracture for this same component exposed to a stress of 300 MPa and made from another alloy with a plane strain fracture toughness of 67.5 MPam

Answers

Answer:

Explanation:

From the given information:

The first thing we need to do is to use the formula used in-plane strain fracture toughness to determine the geometry factor \(\gamma\)

i.e

\(K_1 = \gamma \sigma_{applied} \sqrt{Ra_1}\)

where;

a = crack length

\(\gamma =\) geometry factor

In the first scenario, where;

Plain fracture toughness \(K_1 = 45 \ MPa \sqrt{m}\)

\(\sigma _{applied} = 300 \ MPa \\ \\ a_1 = 6.95 \times 10^{-3} m\)

radius(R) = 3.142

Then, replacing it into the above equation, we have:

\(45 MPa = \gamma (300 \ MPa ) \sqrt{3.142 \times 0.95 \times 10^{-3}} \\ \\ 45 \ MPa = 16.3902715 \gamma \\ \\ \gamma = \dfrac{45 \ MPa}{16.3902715} \\ \\ \gamma \ (geometry factor)= 2.745\)

Now, since we've determined the geometry factor, it will be easier to estimate the max. allowable surface length.

\(K_2 = \gamma \sigma_{applied} \sqrt{Ra _2}\)

\(67.5= 2.745 \times 300 \times \sqrt{3.142 \times a _2}\)

\(67.5= 1459.710372 \sqrt{ a _2} \\ \\ \dfrac{67.5}{ 1459.710372}= \sqrt{ a _2} \\ \\ 0.0462420 = \sqrt{ a _2} \\\\ a_2 = 0.0462420^2 \\ \\ a _ 2 = 0.002138 \\ \\ a_2 = 2.138\times 10^{-3} \ m \\ \\ \mathbf{a_2 = 2.138\ mm}\)

Each fan must go through 3 hours of wiring and 2 hours of drilling. During the next production period, 200 hours of wiring time are available and up to 120 hours of drilling time may be used. Each air conditioner sold yields a profit of $30. Each fan assembled may be sold for a $10 profit. Formulate this LP production-mix situation. (You do not have to solve this problem mathematically or using any software.)

(a) What are the Decision Variables?

(b) What is the Objective Function?

(c) What are Constraint Equations including non-negativity constraints?

Answers

Decision variables are the number of fans and air conditioners, the objective function is to maximize the profit, and constraints are available wiring and drilling hours.

In this manufacturing problem, the Electrocomp Corporation produces two electrical products: air conditioners and large fans. The assembly process for each product requires a certain amount of wiring and drilling. To formulate the linear programming (LP) problem, we need to identify the decision variables, the objective function, and the constraint equations.

Decision variables: Decision variables represent the quantities of the products to be produced. In this case, we use x to represent the number of air conditioners produced and y to represent the number of large fans produced.

Objective function: The objective is to maximize the profit. The profit for each air conditioner sold is $30, and the profit for each fan assembled is $10. Thus, the objective function can be written as: Profit = 30x + 10y.

Constraint equations: The constraints are based on the available wiring and drilling hours. The problem states that there are 200 hours of wiring time available and up to 120 hours of drilling time. The wiring constraint equation is given by 5x + 3y ≤ 200, which represents the total wiring hours used by producing x air conditioners and y large fans. The drilling constraint equation is 6x + 2y ≤ 120, which represents the total drilling hours used. Additionally, the variables x and y should be non-negative, as we cannot produce negative quantities of products: x ≥ 0 and y ≥ 0.

By formulating the LP problem in this way, we have established the decision variables, objective function, and constraint equations that will guide the optimization process to determine the optimal production mix of air conditioners and large fans.

if gx is a polynomial with real coefficients and zeros of 7 (multiplicity 3), 3 (multiplicity 2), 4i, and 55i, what is the minimum degree of gx?

Answers

The minimum degree of the polynomial gx with zeros 7 (multiplicity 3), 3 (multiplicity 2), 4i, and 55i is 9, and this is determined by the total number of zeros including their multiplicities.

What is the minimum degree of the polynomial gx with given zeros and multiplicities?

To find the minimum degree of the polynomial gx with real coefficients and zeros of 7 (multiplicity 3), 3 (multiplicity 2), 4i, and 55i, we need to consider the following:

Since gx has real coefficients, complex zeros must occur in conjugate pairs. Therefore, if gx has zeros 4i and 55i, it must also have zeros -4i and -55i.
The total number of zeros of gx, including multiplicities, determines the minimum degree of the polynomial.

Now, let's count the zeros and their multiplicities:

- 7 (multiplicity 3): 3 zeros
- 3 (multiplicity 2): 2 zeros
- 4i and -4i: 2 zeros
- 55i and -55i: 2 zeros

The total number of zeros is 3 + 2 + 2 + 2 = 9. Therefore, the minimum degree of the polynomial gx is 9.

projective tests face the same drawbacks as other b-data tests, including that

Answers

Projective tests are a type of psychological assessment tool that involve presenting individuals with ambiguous stimuli, such as inkblots or drawings, and asking them to provide interpretations or responses.

While projective tests can provide useful insights into an individual's personality or thought processes, they are not without their drawbacks.

One of the main drawbacks of projective tests, as with other "b-data" tests (behavioral data), is that they are subjective in nature and rely heavily on the interpretation of the examiner. The responses and interpretations may be influenced by the examiner's biases, and there is no clear set of guidelines or criteria for scoring or evaluating the responses. This can lead to inconsistencies and inaccuracies in the results.

Another drawback of projective tests is that they are time-consuming and resource-intensive, requiring a trained examiner to administer and interpret the results. This can make them less practical for use in large-scale assessments or in settings where resources are limited.

Additionally, some individuals may feel uncomfortable or resistant to the ambiguous stimuli presented in projective tests, which can affect their responses and the accuracy of the results.

Percentage of cold work; W_c = 0.2

S_o = 90 kpsi

A) Let's calculate the strain(ε) from the formula;

A_o/A = 1/(1 - W_c)

A_o/A = 1/(1 - 0.2)

A_o/A = 1.25

Thus, strain is;

ε = In(A_o/A)

ε = In(1.25)

ε = 0.2231

Yield strength after the cold work operation is;

S'_y = S_o(ε)^(m)

Plugging in the relevant values;

S'_y = 90(0.2231)^(0.25)

S'_y = 61.854 kpsi

Percentage increase of yield strength = S'_y/(S'_y - S_u) × 100% = (61.854 - 32)/32 × 100% = 93.29%

Ultimate strength after the cold work operation is;

S'_u = S_u/(1 - W_c)

S'_u = 49.5/(1 - 0.2)

S'u = 61.875 kpsi

Percentage increase of ultimate strength = S'_u/(S'_u - S_u) × 100% = (61.875 - 49.5)/49.5 × 100% = 25%

B) Ratio of ultimate strength and yield strength before cold work operations is;

S_u/S_y = 49.5/32

S_u/S_y = 1.547

Ratio of ultimate strength and yield strength after cold work operations is;

S'_u/S'_y = 61.875/61.854 = 1

The ratio after the operation is less than before the operation, thus the ductility reduced.

An air-conditioning system involves the mixing of cold air and warm outdoor before the mixture is routed to the conditional room in steady operation. Cold air enters the mixing chamber at 7 C and 105kpa at a rate of 0. 55 m3/s while warm air enters at 34 C and 105 kpa. The air leaves the room at 24 C.

The ratio of the mass flow rates of the hot to cold air steams is 1. 6

using variable specific heats, determine

a) the mixture temperture at the inlet of the room

b) the rate of heat gain of the room

Answers

To solve this problem, we can use the principle of energy conservation and the equations for the specific heats of air. Let's go step by step:

a) To find the mixture temperature at the inlet of the room, we can use the equation:

(m_h * T_h + m_c * T_c) / (m_h + m_c) = T_m

where:
m_h = mass flow rate of hot air
T_h = temperature of hot air
m_c = mass flow rate of cold air
T_c = temperature of cold air
T_m = mixture temperature

Given that the ratio of the mass flow rates is 1.6, we can say m_h = 1.6 * m_c. Let's substitute the known values:

(1.6 * m_c * 34 + m_c * 7) / (1.6 * m_c + m_c) = T_m

Simplifying the equation:

(54.4 * m_c + 7 * m_c) / 2.6 * m_c = T_m

(61.4 * m_c) / (2.6 * m_c) = T_m

61.4 / 2.6 = T_m

T_m = 23.62°C

Therefore, the mixture temperature at the inlet of the room is approximately 23.62°C.

b) To calculate the rate of heat gain of the room, we can use the equation:

Q = m_c * c_c * (T_m - T_r)

where:
Q = rate of heat gain
m_c = mass flow rate of cold air
c_c = specific heat of cold air
T_m = mixture temperature
T_r = temperature of the room (leaving air temperature)

The specific heat of air can vary with temperature, but for simplicity, let's assume c_c is constant at room conditions.

Substituting the known values:

Q = 0.55 * c_c * (23.62 - 24)

Simplifying the equation:

Q = -0.55 * c_c

Therefore, the rate of heat gain of the room is -0.55 * c_c. Note that the negative sign indicates a heat loss from the room rather than a gain.

Please note that the specific heat values and units are not provided, so the result for the rate of heat gain is expressed relative to c_c. You would need to know the specific heat value and units to obtain an absolute value.

yun anserr hhehehe

primary u.s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. thus, i-405 services i-5, and i-290 services i-90. note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number. given a highway number, indicate whether it is a primary or auxiliary highway. if auxiliary, indicate what primary highway it serves. also indicate if the (primary) highway runs north/south or east/west.
