Post processing for selective laser sintering (SLS) refers to the steps taken after the actual printing process to improve the quality and finish of the final product.
This includes removing excess powder, smoothing and polishing the surface, and dyeing or coating the part for aesthetic or functional purposes. Removing excess powder is important for ensuring accuracy and reducing the risk of contamination. This can be done through a variety of methods, including compressed air or vacuuming. Smoothing and polishing can be achieved through sanding or tumbling, while dyeing or coating can be used to add color, protect the surface, or improve the part's mechanical properties. Post processing is an essential step in the SLS process as it can significantly impact the final product's quality and durability. By carefully considering the necessary post processing steps, designers and manufacturers can ensure that their SLS parts meet their specific needs and requirements.

What is the difference between a cost and a benefit?
Answer:
A cost is something you have to give up or sacrifice and a benefit is something that is gained or is helpful.
Explanation:
In a cost-benefit analysis of a system, an engineer is to simply look at the requirements for the system and determine the costs to build the system, both in financial value and energy value. Additionally, the engineer needs to determine the benefits that would come from choosing a particular path of cost. If the benefits outweigh the cost for the project, then the solution is accepted. Else, the cost outweighs the benefit and the solution is rejected.
Suppose we have two grippers G1 and G2. According to the ASP formalization, when A, B are on the table and Cis on B, can G1 move C onto the table at the same time G2 moves A onto B? Yes No 36 38 39 45 37
No, G1 cannot move C onto the table at the same time G2 moves A onto B according to the ASP formalization. This is because in the ASP formalization, there is a rule that states that only one gripper can move an object at a time. Therefore, it is not possible for G1 and G2 to move objects simultaneously.
This rule ensures that the system is deterministic and predictable, meaning that all of the objects in the system will always be in a known state. This is important for ensuring the safety of the system and its objects, as well as for ensuring efficiency and accuracy in its operations. Additionally, it prevents conflicts from occurring, as two objects cannot occupy the same space at the same time. This rule is also important for ensuring that the system is able to achieve its objectives in the most efficient and accurate way possible.

3. In Question 2, taking actual 2009 sales of $48,000 as the forecast for 2010, what sales would you forecast for 2011, 2012 and 2013 using exponential smoothing and a weigh α based on actual values of (a) 0.4; (b) 0.8?
Using α = 0.4, the forecasted sales for 2011, 2012, and 2013 would all be $48,000, which is the same as the actual sales in 2009.
Using α = 0.8, the forecasted sales for 2011, 2012, and 2013 would also be $48,000.
In both cases, the forecasts for 2011, 2012, and 2013 remain the same as the actual sales in 2009 due to the zero difference between the actual and forecasted sales values.
To forecast sales for 2011, 2012, and 2013 using exponential smoothing, we need to apply the formula:
Forecast for the next period = Previous period's forecast + α * (Actual value - Previous period's forecast)
Given that the actual 2009 sales are $48,000 and are considered the forecast for 2010, we can calculate the forecasts for subsequent years using different values of α.
(a) For α = 0.4:
- Forecast for 2011 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000
- Forecast for 2012 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000
- Forecast for 2013 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000
Using α = 0.4, the forecasted sales for 2011, 2012, and 2013 would all be $48,000, which is the same as the actual sales in 2009.
(b) For α = 0.8:
- Forecast for 2011 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000
- Forecast for 2012 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000
- Forecast for 2013 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000
Using α = 0.8, the forecasted sales for 2011, 2012, and 2013 would also be $48,000.
In both cases, the forecasts for 2011, 2012, and 2013 remain the same as the actual sales in 2009 due to the zero difference between the actual and forecasted sales values.

The following six jobs are to be scheduled on a single machine: Job 1 2 3 4 5 6 Processing time (min.) 80 140 230 100 120 110 Suppose the jobs are processed in numerical order. Compute the average flow time after each job is completed. Round your answer to two decimal places. Average Flow time: minutes In what order would the jobs be processed using the SPT rule? The SPT sequence is -Select- - -Select- - -Select- - -Select- - -Select- - -Select- . Compute the average flow time after each job is completed. Round your answer to two decimal places. The average flow time is equal to minutes. Compare this answer with your answer to part a. The -Select- minimizes flow time and gets the most work done in the least amount of time.
To compute the average flow time after each job is completed, we can use the following steps:1. Calculate the completion time for each job by summing up the processing times of all previously completed jobs.
2. Compute the average flow time by dividing the total completion time by the number of completed jobs.
Here are the calculations:
Job | Processing Time | Completion Time | Average Flow Time
--------------------------------------------------------------
1 80 80 80/1 = 80
2 140 220 220/2 = 110
3 230 450 450/3 = 150
4 100 550 550/4 = 137.5
5 120 670 670/5 = 134
6 110 780 780/6 = 130
The average flow time after each job is completed is as follows:
Job 1: Average flow time = 80 minutes
Job 2: Average flow time = 110 minutes
Job 3: Average flow time = 150 minutes
Job 4: Average flow time = 137.5 minutes
Job 5: Average flow time = 134 minutes
Job 6: Average flow time = 130 minutes
Using the SPT (Shortest Processing Time) rule, the jobs would be processed in the following order:
Job 1 -> Job 4 -> Job 6 -> Job 5 -> Job 2 -> Job 3
After each job is completed, the average flow time is recalculated as shown above.
Comparing the average flow times calculated using the original numerical order and the SPT rule, we can see that the SPT rule minimizes the average flow time and gets the most work done in the least amount of time.

Compute and plot the bending stress profile
along the cross-section y-axis. Show values at A,B,C and D
To plot the bending stress profile, create a simple graph with y as the horizontal axis and sigma as the vertical axis. The values at A, B, C, and D can be indicated on the graph.
What is the bending stress profile along the cross-section y-axis?To compute the bending stress profile, we need to determine the maximum moment of inertia and the distance of the extreme fibers from the neutral axis.
Assuming that the cross-section is symmetric and uniform, we can determine the moment of inertia as follows:
I = 2[(1/2)(1)^3(0.125) + (1/2)(1)^3(0.125)] + (1)(1)(0.5)^3
I = 0.21875 in^4
The distance from the neutral axis to the extreme fibers is half of the height of the cross-section, which is 0.5 inches.
Using the bending stress formula:
sigma = M*y/I
where M is the applied moment, y is the distance from the neutral axis, and I is the moment of inertia.
Computing the bending stress at each point of interest:
At point A (y = 0.5 inches), sigma = (-50 kip-in)(0.5 in)/(0.21875 in^4) = -228.57 psi
At point B (y = 0.25 inches), sigma = (-50 kip-in)(0.25 in)/(0.21875 in^4) = -457.14 psi
At point C (y = 0 inches), sigma = (-50 kip-in)(0 in)/(0.21875 in^4) = 0 psi
At point D (y = -0.25 inches), sigma = (-50 kip-in)(-0.25 in)/(0.21875 in^4) = 457.14 psi

A four-lane divided multilane highway (two lanes in each direction) in rolling terrain has five access points per mile and 11-ft lanes with a 4-ft shoulder on the right side and a 2-ft shoulder on the left. The peak-hour factor is 0.84 and the traffic stream consists of 6% trucks, 4% buses, and 3% recreational vehicles. The driver population adjustment factor is estimated at 0.90. If the analysis flow rate is 1250 pc/h/ln, what is the peak-hour volume
Answer:
peak-hour volume = 1890 veh/h
Explanation:
Determine the peak-hour Volume
Applying the equation below
Vp = v / ( PHF * N * Fg * Fdp ) -------------- ( 1 )
where :
Vp = 1250
v ( peak - hour volume ) = ?
PHF ( peak hour factor ) = 0.84
N = 2 lanes per direction
Fg ( grade adjustment for rolling terrain ) = 0.99 ≈ 1
Fdp = 0.90
Back to equation 1
v = Vp ( PHF * N * Fg * Fdp )
= 1250 ( 0.84 * 2 * 1 * 0.90 )
= 1890 veh/h

The appropriate answer is "0.0043".
Explanation:
The given values is:
Error probability,

Received digits,
n = 10
and,
\(x\sim Binomial\)
As we know,
⇒ \(P(x)=\binom{n}{x}p^xq^{n-x}\)
Now,
⇒ \(P(x >1) =1- \left \{ P(x=0)+P(x=1) \right \}\)
⇒ \(=1-\left \{\binom{10}{0}(0.01)^0(0.99)^{10-0}+\binom{10}{0}(0.01)^1(0.99)^{10-1} \right \}\)
⇒ \(=1-0.9957\)

what is the expected value of the difference between the strength of a cable and the weight of a light fixture
The expected value of the difference between the strength of a cable and the weight of a light fixture cannot be determined without specific information about their probability distributions.
The expected value is a measure of central tendency that represents the average value we would expect to obtain from a random variable. To calculate the expected value of the difference between the strength of a cable and the weight of a light fixture, we would need to consider the probability distribution associated with each variable.
If we have the probability distributions for the strength of the cable and the weight of the light fixture, we can calculate the expected value by taking the difference between the two variables and multiplying it by the corresponding probabilities. We would sum up these products for all possible values of the variables.
However, without specific information about the probability distributions or any assumptions made, we cannot calculate the expected value. The expected value would vary depending on factors such as the variability and correlation between the strength of the cable and the weight of the light fixture.
