  • 13. Team T P-A-1-T: Cooler is better Cooler is better Curver® wants to put a children's beaker on the market that keeps a portion of juice nicely cool from home until morning break. They have a 0.5 L cup that serves as a starting point and they ask you to test this cup for its insulating qualities and give advice on the design of the beaker. The 0.5 L cup is obviously too big. They want to know the (dis)advantages of each of your improvements. Fiction case study Courtesy of Challenge the future 13

Gardena® needs to quantify their claim regarding the performance of their pressure sprayer (‘drukspuit’ in Dutch). They have asked you to help them do so and give advice on the design as well, especially on velocity of the flow and the ratio between water and air inside the barrel. 1.Release the largest possible quantity of water when the valve is completely open in one “full charge”; 2.Estimate the speed of water in the process.

  • 44. Planning & Evaluation The Experiment Assignment are not crystal clear Why should I do experiment? My model is right? t doesn't matter how beautiful your theory is, What is the right answer? t doesn't matter how smart you are. ? f it doesn't agree with experiment, it's wrong. Richard Phillips Feynman Nobel Prize in Physics (1965)
  • 45. Planning & Evaluation The purpose of models Assignment are not crystal clear Why should I do experiment? My model is right? he purpose of models is not to What is the right answer? t the data but to sharpen the uestions. Samuel Karlin National medal of science
  • 46. Planning & Evaluation Your model & Your design Assignment are not crystal clear Why should I do experiment? My model is right? on’t let the noise of others’ What is the right answer? inions drown out your own ner voice Steve Jobs
  • 47. Planning & Evaluation In short sign is not for philosophy, it's for life. Issey Miyake
  • 48. Planning & Evaluation Suggested schedule  Experiments  Verify / correct your model(s)  Fine-tuning: reports  Documentation Week  Fine-tuning: models  Prepare presentations Attention: We have very short weeks this year! Week Week Week 4.2 4.3 4.4 Time flies and four weeks are very short Understand the assignment  Evaluation and verification Think about the product, list cause-effect,  Finish reports Draft abstract mode, list assumptions Documentation Experiments 4.5
  • 49. Planning & Evaluation P-A-1: Thinking before doing Modelling Thinking Model ? ? ? System Cause-effect Relations Experiment Choices Laws What shall I get? How can I do? 1st & 2nd experiment
  • 50. Planning & Evaluation Steps: Chronological  Setup an experiment to:  Thought simulation, what do you need to model it?  You can find them thought research or measurements? 1 2  Find the unknown parameters;  Verify the draft abstract model; 3 4 Think – how does it work?  Draft a time-dependent abstract model Cause – effect; Either on paper or on Maple®
  • 51. Planning & Evaluation Steps: Chronological  Verify it with your own thoughts and verify it with another  Hand in reports experiment by different conditions; 5 6 7 8 h your abstract model in Maple® or any  Evaluate it (and advice on improvement of the design), which is necessary;  Point out the sources of errors between your models and the measurements.
  • 52. Planning & Evaluation A good schedule is a must: A rough example Think&Documenting Draft / Assumptions Exp. Guide lines Experiment 1 Verify the model Experiment 2 Fine-tuning, Re + Pre Reserved Upload 7:00PM Eva, Rec&Reporting
  • 53. Planning & Evaluation P-A-P Presentation 10% of your final grades of 10 minutes P-A-1 PPT or poster + Q&A
  • 54. Planning & Evaluation Report – Logical: Grading Criteria  Abstract Model with Maple® file (appendix?)  Experiment and its contribution in Modelling 1  Conclusions & recommendations 2 3 4 ntroduction  Evaluation Problem Definition  Optimization (possible new design, new models) Using < 15 pages Hardcopy specified is recommended @ cover page P-A-P
  • 55. Planning & Evaluation Question & Answers You may ask your workshop coach for Maple problems (not too much about the model), rovided that you finished that workshop and he/she also has time.
