Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Finish the assembly of hardware (Kimi)
Finish the draft of image processing code and test its robustness (Kimi)
Test the chamber and notice leaking issue (Kimi)
Accomplishments from Previous Week
Finish machining all parts and assembly (Kimi)
Finishing the draft of image processing code (Kimi)
Test and reprint the chamber (Kimi)
3D printed a new chamber and honeycombs of different configurations (Teng)
Improved the functionality of the pump control Matlab code (Teng)
Calibrated the actual flow rate versus the pump rpm speed (Damien, Yuling, and Teng)
Established that the design can only accommodate flow in one direction (Damien)
Created new design for tubing/nozzle system using quick disconnect valves that will allow the easy insertion of test objects (Damien)
Attempted to test actual plankton for imaging -- not successful (Damien)
Purchased a smaller tubing that will give us a better flow rate range and the tubing fitting. (Yuling)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish image process code (Kimi)
Resolve water leaking issue (Kimi and Yuling)
Resolve low volume rate issue (Yuling)
Determine whether the Matlab code can read the feedback from a text file that is written by the image processing code at the same time (Teng)
Determine the pump speed that can keep the object in the field of view and estimate the proportional gain based on that value (Teng）
Assemble new tubing/nozzles, change reservoir tank design/placement (Damien)
Create method and conduct test for measuring actual velocity profile (Damien)
Verify COMSOL since chamber design has changed
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
7 May 2015 meeting with Jules at SIO
Sponsor provided C++ code with openCV library for image process (5/7, in person with Ben)
Suggested to use real plankton for testing purpose.
Have done test with plankton from sponsors. However plankton are relatively small for observation in field of view.Also plankton can swim very fast in random direction which makes it hard for image processing.
Grease O-Rings (talk to Paul)
Only observe a single, sinking, object for now (plankton or otherwise)
Epoxy resin crumbles
Optimal to use less salt and decrease object density instead
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
6 May 2015
Double check on Parker for O-ring groove design (5/6, in person)
Use larger cross section tube (5/6, in person)
Use still tube except tube in the peristaltic pump.
Put water tank above chamber
Quick disconnect on top for putting in plankton (sealed on one side?)
Need water shut off
Salinity measurement
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Risks and Areas of Concern
Communication between C++ and MATLAB
Flow profile
Image processing for small size plankton
Resources or Information Required but not Available
ACMS remote access to 32GB Linux machine is still having issues, have met with ACMS support
needs to be fixed so we can do final simulation of flow to calculate velocity error
