OUR TEAMLAB 3 WRITE-UPOriginal System: PCR ResultsPCR Test Results
* Ave. INTDEN = Average of ImageJ integrated density values from three Fluorimeter images
Bayes Theorem equation: P(A|B) = P(B|A) * P(A) / P(B)
New System: Design StrategyWe concluded that a good system Must Have:
New System: Machine/ Device EngineeringSYSTEM DESIGN
KEY FEATURES We chose to include these new features
[OR] We chose keep the devices the same as the original system
INSTRUCTIONS
New System: ProtocolsDESIGN We chose to include these new approaches/ features
[OR] We chose keep the protocols the same as the original system
PROTOCOLS
New System: Research and DevelopmentBACKGROUND
DESIGN
New System: Software[THIS SECTION IS OPTIONAL. If your team has creative ideas for new software, and new software is a key component included in your new protocols, R&D, or machine design, you may describe it here. You will not receive bonus points, but a solid effort may raise your overall page layout points. If you decide not to propose new software, please delete this entire section, including the ==New System: Software== header.]
