FSE 100 Extra Credit (20 points) Instructions: Read the description below and work through the design process to build an automated waste sorting system. Turn in the following deliverables in one document, typed: 1. Problem Statement – 1 point 2. Technical System Requirements (at least 3 complete sentences using “shall”) – 3 points 3. Judging Criteria (at least 3, explain why you chose them) – 2 points 4. AHP – 2 points 5. Summaries of your 3 design options (paragraph minimum for each option) – 3 points 6. Design Decision Matrix – 3 points 7. Orthographic Drawing of your final design (3 projections required) – 3 points 8. Activity Diagram of how your sorter functions – 3 points Description: The city of Tempe waste management has notified ASU that due to the exceptional effort the Sundevil students have made in the sustainability area, ASU has been contributing three times the amount of recyclable materials than what was predicted on a monthly basis. Unfortunately, due to the immense amount of materials being delivered, the city of Tempe waste management has asked for assistance from ASU prior to picking up the recyclable waste. They have requested that ASU implement an automated waste sorting system that would pre-filter all the materials so the city of Tempe can collect the materials based on one of three types and process the waste much faster. ASU has hired you to design an automated sorter, but due to the unexpected nature of this request, ASU prefers that this design be as simple and inexpensive to build as possible. The city of Tempe would like to have the waste categorized as either glass, plastic, or metal. Paper will not be considered in this design. Any glass that is sorted in your device needs to stay intact, and not break. Very few people will be able to monitor this device as it sorts, so it must be able to sort the items with no input from a user, as quickly as possible. This design cannot exceed 2m in length, width, or height, but the weight is unlimited. ASU is not giving any guidance as to the materials you can use, so you are free to shop for whatever you’d like, but keep in mind, the final cost of this device must be as inexpensive as possible. Submit through Blackboard or print out your document and turn it in to me no later than the date shown on Blackboard.

Remember that the doubling time (in years) for an exponentially growing population is estimated by dividing 70 by the growth rate of the population (as a percentage): Doubling time (in years) = 70 / annual growth rate (%) Part A Drag the values on the left to the appropriate blanks on the right to complete the sentences. Not all values will be used. ANSWER: Concept Review: Calculating Population Growth Rates Populations grow larger from births and immigration and grow smaller from deaths and emigration. The growth rate for a population is determined by adding the birth rate and the immigration rate, and then subtracting the death rate and the emigration rate (all rates expressed as the number per 1,000 individuals per year): (birth rate + immigration rate) (death rate + emigration rate) = growth rate Positive population growth rates lead to population increases, and negative population growth rates lead to population declines. Part A Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,000/year Immigration rate = 5 per 1,000/year Emigration rate = 1 per 1,000/year What is the growth rate for this population?

ANSWER: Part C Suppose you are studying a population with the following characteristics: Birth rate = 10 per 1,000/year Death rate = 12 per 1,000/year Immigration rate = 2 per 1,000/year Emigration rate = 3 per 1,000/year What is the growth rate for this population?
