Computer Project Overview You are to perform a 2D heat transfer simulation of the thermal system shown in the schematic below. All items, including justification, plots, and code must be put WITHIN A SINGLE WORD DOCUMENT, USING THE FILENAME “lastname.firstname”. Your document must be submitted into Safeassign in bblearn (in the computer project folder) by the date/time listed above. You will have the option of doing either of 2 different geometries for your simulation. The first geometry is easier, but will have a maximum possible score of 80%. The other geometry is more complex and is the only way to get a full 100% on the project. Your code must be able to handle any mesh size that is a multiple of 10 (e.g. 10×10, 20×20, etc). Code that does not allow a variable mesh size will result in a zero grade for the project. This project may or may not be painful, but I assign it because this is the direction that engineering (not just heat transfer) is going. Additionally, many students have expressed appreciation for the project, although for most of them that was after the fact. I include a couple quotes below from previous students who emailed me after graduating: “My mentor, who is the Lead Engineer for the testing group at Orbital, was SUPER impressed when I told him about the MATLAB project I did for heat transfer. My tears and extra gray hairs were worth it. Tell that to the new seniors when they whine about the project next year. “ “side note, i learned A LOT. i knew very little about matlab prior to this. thank you” “I gotta say though, I think the main thing that pushed me into the realm of being qualified for this job is my capability in Matlab. Your HT project you had all of us do was paramount in kicking me into gear.” Deliverables Your submitted document must contain all of the following:  A one paragraph justification of how you know that your simulation is valid. Your justification must address EACH of the following tests: o Heat flows on each individual node should add up to 0 on every node (note: if done correctly, your sums should be something like 10-10) o Net heat flow summed over the boundaries of your simulation should match the heat generated in the system (again, if correct these sums should match within 10-10) o Your temperature profile should match what is physically expected given EACH of the prescribed boundary conditions (describe SPECIFICALLY what EACH boundary condition should do to the temperature profile, and verify that this is reflected in your 3D temperature map) o Doubling your mesh density should not affect your solution (i.e. your calculated heat flows) by more than 0.5% o If you do not get a reasonable answer, show how your solution is NOT valid and discuss HOW you would use these to check whether your code is valid  A table listing the quantity of heat transfer per unit depth along each of the non-insulated edges, using a positive value for heat transfer into the solid and negative for heat transfer out of the solid. This should be the TOTAL (summed) heat transfer along each edge.  A 3D projection of the temperature distribution (the ‘surf’ command may prove useful), arranged in a way that clearly shows the full temperature distribution, in the correct orientation.  Plots of the temperature profiles along each of the edges. Put these together into a single figure with a 3×2 subplot (not a single plot) using the subplot command. Begin with the bottom edge, then work your way clockwise around the geometry.  The code you wrote to complete the project Deadlines While there are no deliverables associated with the deadlines below other than the final submission, I will not provide assistance to you on the listed subtasks after their associated deadlines, unless it is during my normal office hours AND there is no one else waiting to ask questions. Also make use of the Finite Difference Overview, MATLAB primer, and tips document which are posted in bblearn.  Deadlines o Deadline 1: 11/11/2015. By this time, you should have done the following:  Make sure you understand how FD simulations work, by a) reviewing your lecture notes; b) reading Chapter 4 of your textbook; and c) reviewing the Finite Difference Overview posted in bblearn  Chosen a numbering scheme for your nodes (where is node ‘1’, how do the nodes increment, etc.)  Identified each of the ‘types’ of nodes present and determined the appropriate energy balance relation for each of them  Determined the LOGIC to identify the node ‘type’ for an arbitrary node number ‘i’ (based on your numbering scheme and the size of the mesh ‘n’)  For a given arbitrary node ‘i’, have a way of identifying the node numbers of all neighboring nodes using only ‘i’ and ‘n’.  Written pseudocode that shows the logic of your program. If you do not have pseudocode, I cannot help you with your coding. o Deadline 2: 11/18/2015. By this time, you should have done the following:  Have code that can identify the node numbers for all neighboring nodes for an arbitrary node ‘i’ (this will probably involve a series of ‘if’ statements)  Have code that can identify which energy balance equation should be applied for any arbitrary node ‘i’ (again, this will probably involve a series of ‘if’ statements) o Deadline 3: 11/20/2015. By this time, you should have done the following:  Have code that correctly populates the coefficient matrix and ‘b’ vector by:  Iterating through every node  Determining which energy balance equation should be applied for each node  Determining the appropriate columns for the coefficients of the energy balance equation (this comes from knowing the node numbers for all neighboring nodes)  Have code that calculates the temperature distribution from the coefficient matrix and ‘b’ vector o Deadline 4: 11/20/2015. FINAL SUBMISSION. This week should be dedicated to:  Creating the required plots  Calculating the required heat flows  Validating/verifying your simulation Plagiarism Note that this is an INDIVIDUAL project. While you may collaborate, you may NOT share code. Two people independently writing code will NEVER end up with the same code at the end of the day. Merely changing variable names or comments is not sufficient. I have been continuously impressed at how good the plagiarism checking software is at picking out copied code, both from other students and from internet sources. Plagiarized code from any class, past or present, will result in a severely reduced score (potentially a zero) and a report of academic dishonesty. Moreover, presenting results that were not obtained by your code will result in a zero grade and a report of academic dishonesty. Please do not test this – I derive no joy from catching people in plagiarism. Grading The grade breakdown will be as follows:  Report: 30 pts o 20 pts: Justification of the validity of your code o 5 pts: required plots shown in report o 5 pts: required heat transfer values shown in table  Code: 70 pts (50 pts max if you choose the easier geometry) o 45 pts (35 for easier geometry): coefficient matrix generation o 15 pts: (10 for easier geometry): calculation of heat transfer on edges o 10 pts (5 for easier geometry): temperature matrix and correct surface plot  Subtractions: o Up to -10 points for grammar and writing clarity o -5 points for using imaginary nodes (for the harder geometry) o -5 points for incorrect file name and file format o -5 points/day late (no more than 6 days allowed) o Up to 100% deduction for plagiarized code o 100% deduction for reporting results not generated by your submitted code o 100% deduction for submitting code that cannot handle a variable mesh size Skeleton Pseudocode The code listed below is intended to help you organize your thought process on this project. Feel free to use it or not as you see fit.

Solve for T values %rearrange T values into matrix to make surface plot %verify sum of qin to each node adds to 0 %calculate heat flows on edges, verify that it matches generation %make edge plots Project Geometries Easier Geometry (Max Score is 80/100) The overall size is 1mx1m. The geometry is designed to work with any mesh size that is a multiple of 10×10. Harder Geometry The overall size is 1mx1m. The geometry is designed to work with any mesh size that is a multiple of 10×10.

AUCS 340: Ethics in the Profession Written Video Presentation Response Paper As a component of this course you will have the opportunity to view the movie “My Sister’s Keeper” (2009) starring Cameron Diaz, Jason Patric and Abigail Breslin. This movie is an adaptation of the book of the same title written by Jodi Picoult. Your answers are to be based on the movie adaptation of the book. While this movie offers a profound family story it also reflects upon issues related to current technological advancements in medicine and it will also offer you the opportunity to identify and respond to some of ethical issues represented in the movie. After viewing this movie, respond to the following questions. Your answers should be insightful and reflective of the topics researched for class, in regards to the ethical treatment to be afforded all citizens. 1. Identify at least two ethical issues/situations portrayed in the movie. These issues must be separate from the issue of stem cell research which will be addressed in questions later in this assignment. 2. Discuss a solution or solutions to each of the ethical issues that you identified in question number one. If multiple solutions are offered, identify your solutions as to first preference, second preference and so on until concluded. 3. Are your solutions feasible? What cost would it take to implement your solutions: taxes, wholesale system changes, society as a whole? 4. This movie incorporates the topic of stem cell usage for the treatment of medical conditions. Discuss the difference between the acquisition of fetal stem cells and adult stem cells. List ethical arguments both for and against the concept of expanding stem cell research to have a more active role in the development of treatment options for patients. 5. List at least five medical conditions that have the potential to be treated with stem cells. 6. Discuss the attitude of former President George W. Bush and current President Barack Obama in their philosophical approach to the issue of stem cell research. (Do they accept or reject the idea of stem cell research? Is there legislation that supports their views?) 7. From your previous assignment on the administration of healthcare in the United States you should have a general view of some of the problems facing the distribution of healthcare services in the United States. Research the changes to the health care system as proposed by President Barack Obama, and passed into legislation as the Patient Protection and Affordable Care Act, and outline/list these changes for healthcare reform in the United States. What are the financial implications of this plan? What portions of this plan do you find feasible to solving the problem of inadequate healthcare coverage for all Americans? What portions of this plan do you find unacceptable? 8. Overall, do you feel that these proposed changes will benefit or cause harm to the distribution of healthcare in the United States? Explain the rationale behind your answer. 9. Discuss problems in implication of the Affordable Care Act (ACA) that have occurred since October 2013. Have theses issues been resolved? 10. To date, how many people have been enrolled in the Affordable Care Act? Is this number above expectations, below expectations or at the level of expectation for enrollment at this point in time? 11. How will future enrollment in Medicaid be affected by the passage of the Affordable Care Act? This assignment is due on the date posted in the syllabus. Grading: Content of responses: thought provoking, rationale defended = 70% of grade Correct use of sentence structure, grammar and spelling, stapled for presentation = 20% of grade Appropriate use of citations and references = 10% of grade (No www.Wikipedia.com) It is expected that the length of the computer generated responses to these questions will be presented in at least three – four pages of text. Use 12 font and double spacing for your responses. Format: you may either respond to the questions as a running essay or use the questions as a header for each individual answer.

Computer Project Overview You are to perform a 2D heat transfer simulation of the thermal system shown in the schematic below. All items, including justification, plots, and code must be put WITHIN A SINGLE WORD DOCUMENT, USING THE FILENAME “lastname.firstname”. Your document must be submitted into Safeassign in bblearn (in the computer project folder) by the date/time listed above. You will have the option of doing either of 2 different geometries for your simulation. The first geometry is easier, but will have a maximum possible score of 80%. The other geometry is more complex and is the only way to get a full 100% on the project. Your code must be able to handle any mesh size that is a multiple of 10 (e.g. 10×10, 20×20, etc). Code that does not allow a variable mesh size will result in a zero grade for the project. This project may or may not be painful, but I assign it because this is the direction that engineering (not just heat transfer) is going. Additionally, many students have expressed appreciation for the project, although for most of them that was after the fact. I include a couple quotes below from previous students who emailed me after graduating: “My mentor, who is the Lead Engineer for the testing group at Orbital, was SUPER impressed when I told him about the MATLAB project I did for heat transfer. My tears and extra gray hairs were worth it. Tell that to the new seniors when they whine about the project next year. “ “side note, i learned A LOT. i knew very little about matlab prior to this. thank you” “I gotta say though, I think the main thing that pushed me into the realm of being qualified for this job is my capability in Matlab. Your HT project you had all of us do was paramount in kicking me into gear.” Deliverables Your submitted document must contain all of the following:  A one paragraph justification of how you know that your simulation is valid. Your justification must address EACH of the following tests: o Heat flows on each individual node should add up to 0 on every node (note: if done correctly, your sums should be something like 10-10) o Net heat flow summed over the boundaries of your simulation should match the heat generated in the system (again, if correct these sums should match within 10-10) o Your temperature profile should match what is physically expected given EACH of the prescribed boundary conditions (describe SPECIFICALLY what EACH boundary condition should do to the temperature profile, and verify that this is reflected in your 3D temperature map) o Doubling your mesh density should not affect your solution (i.e. your calculated heat flows) by more than 0.5% o If you do not get a reasonable answer, show how your solution is NOT valid and discuss HOW you would use these to check whether your code is valid  A table listing the quantity of heat transfer per unit depth along each of the non-insulated edges, using a positive value for heat transfer into the solid and negative for heat transfer out of the solid. This should be the TOTAL (summed) heat transfer along each edge.  A 3D projection of the temperature distribution (the ‘surf’ command may prove useful), arranged in a way that clearly shows the full temperature distribution, in the correct orientation.  Plots of the temperature profiles along each of the edges. Put these together into a single figure with a 3×2 subplot (not a single plot) using the subplot command. Begin with the bottom edge, then work your way clockwise around the geometry.  The code you wrote to complete the project Deadlines While there are no deliverables associated with the deadlines below other than the final submission, I will not provide assistance to you on the listed subtasks after their associated deadlines, unless it is during my normal office hours AND there is no one else waiting to ask questions. Also make use of the Finite Difference Overview, MATLAB primer, and tips document which are posted in bblearn.  Deadlines o Deadline 1: 11/11/2015. By this time, you should have done the following:  Make sure you understand how FD simulations work, by a) reviewing your lecture notes; b) reading Chapter 4 of your textbook; and c) reviewing the Finite Difference Overview posted in bblearn  Chosen a numbering scheme for your nodes (where is node ‘1’, how do the nodes increment, etc.)  Identified each of the ‘types’ of nodes present and determined the appropriate energy balance relation for each of them  Determined the LOGIC to identify the node ‘type’ for an arbitrary node number ‘i’ (based on your numbering scheme and the size of the mesh ‘n’)  For a given arbitrary node ‘i’, have a way of identifying the node numbers of all neighboring nodes using only ‘i’ and ‘n’.  Written pseudocode that shows the logic of your program. If you do not have pseudocode, I cannot help you with your coding. o Deadline 2: 11/18/2015. By this time, you should have done the following:  Have code that can identify the node numbers for all neighboring nodes for an arbitrary node ‘i’ (this will probably involve a series of ‘if’ statements)  Have code that can identify which energy balance equation should be applied for any arbitrary node ‘i’ (again, this will probably involve a series of ‘if’ statements) o Deadline 3: 11/20/2015. By this time, you should have done the following:  Have code that correctly populates the coefficient matrix and ‘b’ vector by:  Iterating through every node  Determining which energy balance equation should be applied for each node  Determining the appropriate columns for the coefficients of the energy balance equation (this comes from knowing the node numbers for all neighboring nodes)  Have code that calculates the temperature distribution from the coefficient matrix and ‘b’ vector o Deadline 4: 11/20/2015. FINAL SUBMISSION. This week should be dedicated to:  Creating the required plots  Calculating the required heat flows  Validating/verifying your simulation Plagiarism Note that this is an INDIVIDUAL project. While you may collaborate, you may NOT share code. Two people independently writing code will NEVER end up with the same code at the end of the day. Merely changing variable names or comments is not sufficient. I have been continuously impressed at how good the plagiarism checking software is at picking out copied code, both from other students and from internet sources. Plagiarized code from any class, past or present, will result in a severely reduced score (potentially a zero) and a report of academic dishonesty. Moreover, presenting results that were not obtained by your code will result in a zero grade and a report of academic dishonesty. Please do not test this – I derive no joy from catching people in plagiarism. Grading The grade breakdown will be as follows:  Report: 30 pts o 20 pts: Justification of the validity of your code o 5 pts: required plots shown in report o 5 pts: required heat transfer values shown in table  Code: 70 pts (50 pts max if you choose the easier geometry) o 45 pts (35 for easier geometry): coefficient matrix generation o 15 pts: (10 for easier geometry): calculation of heat transfer on edges o 10 pts (5 for easier geometry): temperature matrix and correct surface plot  Subtractions: o Up to -10 points for grammar and writing clarity o -5 points for using imaginary nodes (for the harder geometry) o -5 points for incorrect file name and file format o -5 points/day late (no more than 6 days allowed) o Up to 100% deduction for plagiarized code o 100% deduction for reporting results not generated by your submitted code o 100% deduction for submitting code that cannot handle a variable mesh size Skeleton Pseudocode The code listed below is intended to help you organize your thought process on this project. Feel free to use it or not as you see fit. However, if you do not follow this general approach, I will be unable to help you. ****** %Choose mesh size (e.g. n=10 for 10×10, 20 for 20×20, etc.) %Calculate number of nodes (probably something related to n2) %Run a for loop to define all the nodetypes and put them in their proper location for i=1:allnodes if i == xxxxx %use if statements (may need more than one) to determine where node ‘i’ is %e.g. left boundary, bottom right corner, etc. Should be able to determine %using only i and n %Must be node type 1 (for example) Nodetype(i) = 1 elseif i==xxxxx %use if statements to determine where node ‘i’ is %must be node type 2 (for example) Nodetype(i) = 2 elseif i ==xxxx %continue for all node types end end %Run a single for loop to populate the coefficient matrix one row at a time for i =1:allnodes if nodetype (i) == 1 %use energy balance equation for node type 1 %put appropriate coefficients into the correct columns of row i for coefficient %matrix and b vector elseif nodetype(i) ==2 %use energy balance equation for node type 2 %etc., etc. end end %coefficient matrix and b vector should now be populated. Solve for T values %rearrange T values into matrix to make surface plot %verify sum of qin to each node adds to 0 %calculate heat flows on edges, verify that it matches generation %make edge plots Project Geometries Easier Geometry (Max Score is 80/100) The overall size is 1mx1m. The geometry is designed to work with any mesh size that is a multiple of 10×10. Harder Geometry The overall size is 1mx1m. The geometry is designed to work with any mesh size that is a multiple of 10×10.
