  1. Engineering Models I

  2. Course Objectives • To explore the application of algebra, trigonometry, and calculus to various engineering disciplines. • To learn the fundamentals of programming and good programming practices and utilize these skills to solve numerical problems and create numerical algorithms. • To develop good problem solving skills by applying problem solving strategies to a variety of engineering problems with MATLAB®. • To cultivate effective team-work and communication skills through lab work and a design project.

  3. Course Structure • Lecture: • Meets once per week for 55 minutes • Bring your laptops • Attendance is required (5% of grade) • Students are expected to view videos prior to attending lecture • Short Blackboard quizzes at start of lecture • Recitation: • Meets once per week for two hours • Bring your laptops • Attendance is required • Homework assignments and recitation work from the previous week are due at the beginning of recitation

  4. Expectations • Attendance is required for both lecture and recitation. • Students should prepare for lecture each week by viewing the videos prior to lecture and doing the suggested exercises. • Students should prepare for recitation each week by reading through the lab prior to recitation and completing any required pre-work. • Assignments must be turned in on time. Homework will not be accepted late and quizzes cannot be made up. • Working with other students is encouraged. However, all assignments that you turn in must be your own work! All students turning in duplicate documents will receive a zero on the assignment including the student that actually completed the work.

  6. Engineering Your World

  7. Engineers are Problem Solvers and Innovators • Engineers recognize needs or problems • Engineers create new products or systems and make existing products or systems faster, cheaper, more reliable, … • Engineers must be good problem solvers, understand their discipline, be adept at using design tools, be meticulous in checking designs, and be able to communicate and work well with other people (both technical and non-technical).

  8. Health Care • Prosthesis • Medical devices like hearing aids • Computer Diagnostic Tools • X-rays, MRIs, … • Surgical Robots

  9. Personal Electronic Devices • Computers • Cell Phones • Digital T.V. • DVDs • Digital Cameras • Kindle • iPods and MP3 players

  10. Structures • Buildings • Bridges • Canals • Dams

  11. Transportation • Cars • Planes • Trains • Boats

  12. Manufacturing • Robotics • Conveyer Systems • Packaging

  13. Infrastructure • Safe Water Supply • Sewage Disposal • Roads • Power

  14. Space Exploration The on-board program that allowed Curiosity to successfully land on Mars had over 500,000 lines of code.

  15. Impact of Computers

  16. Data Collection & Analysis New I-35W bridge in Minneapolis Old bridge collapsed August 1, 2007 killing 13 people and injuring 145 others. The bridge has 500 Smart Bridge sensors. “Some sensors record the bridge's response to vibration, corrosion and environmental conditions. Other sensors trigger an automated anti-icing system when wind, temperature and humidity reach certain levels. Others detect unauthorized activity on and around the bridge”. http://minnesota.publicradio.org/display/web/2012/08/01/news/high-tech-new-i-35w-bridge NASA’s Orbiting Carbon Observatory (OCO-2): Due to launch next July. Will take 200,000 samples of the Earth’s atmosphere per day to track atmospheric levels of CO2 (73 million data points per year). http://oco.jpl.nasa.gov/

  17. Data Collection & Analysis PillCam® video capsule An Israeli biomedical company, Given Imaging, has developed a minimally invasive tool for diagnosing diseases of the GI tract that substantially improves visual imaging of the small intestine. The capsule, which is swallowed by the patient, contains a tiny video camera that transmits 50,000 digital images from the GI tract to a receiver fitted in a belt around the patient’s body. All 50,000 images are downloaded to a PC for analysis. http://www.mathworks.com/company/user_stories/Given-Imaging-Develops-Camera-in-a-Capsule-Using-MATLAB-to-Improve-the-Diagnosis-of-Gastrointestinal-Disorders.html

  23. Problem Solving

  24. Engineers Solve Problems not Exercises Problem Solving Exercise Solving • Problem is poorly defined – all of the necessary information is not provided. • The path to a solution is not obvious. Information must be gathered, questions must be asked, and new knowledge may be needed. • Multiple solutions are possible and analysis is required to choose the optimal solution. • Problem solving requires synthesis or integration of knowledge from several areas • Exercise is well-defined with all the needed information provided in the problem statement. • All the background for solving the exercise has been provided (examples, appropriate formulas, …). • There is one right answer. • Solving an exercise typically only requires knowledge of the material being covered in class or closely related pre-requisite courses.

  25. Engineering Education • In an engineering education, exercise solving is important because it builds technical competence in your field – a necessary skill for effective problem solving in engineering. • In an engineering education, problem solving is important because it requires integration of knowledge, self-directed learning, creativity, good analytical skills, effective communication, and an ability to work productively on a team.

  26. DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT • DEFINE THE PROBLEM • What exactly is the problem? • What are the constraints?

  27. GATHER INFORMATION • Review any relevant available data • Gather more data if necessary • Talk to people involved and/or experts • Learn what you don’t know • Avoid information overload DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT

  28. DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT • GENERATE SOLUTIONS • Brainstorm – don’t evaluate! • Don’t get hooked on the first solution • that appears to work • Be creative and innovative – a diverse set • of solutions leads to a better final solution • Don’t create artificial constraints

  29. DECIDE ON BEST SOLUTION • Does the solution solve the problem? • Does the solution meet the constraints? • What is the cost of the solution? • Is implementation difficult and/or time consuming? • How does the solution impact users? DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT

  30. DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT IMPLEMENT THE SOLUTION If possible, test the solution first through simulation, prototype, and/or test market.

  31. EVALUATE THE SOLUTION Now that the solution has been implemented, does it indeed solve the problem? DECIDE EVALUATE GATHER DEFINE GENERATE IMPLEMENT

  32. Characteristics of Effective Problem Solvers • Take time to understand and define the problem. Draw sketches, charts, or figures, write equations, and/or re-describe the problem. • Take time to gather critical background information and data. • Able to draw on and apply pertinent subject knowledge. • Follow a systematic process, using a variety of tactics, to tackle the problem. • Do not give up easily – persevere when stuck – willing to deal with ambiguity and able to cope with frustration or stress. • Open to alternative viewpoints and opinions. • Emphasize accuracy over speed. Check and re-check.
