<table border="1" cellpadding="1" cellspacing="1"> <tbody> <tr> <td>Name</td> <td>Today's Update</td> <td>Plans for Tomorrow</td> </tr> <tr> <td>Alex M.</td> <td> <p>Worked with Alex on finding the variables Amy suggested to us in AraSim. We found the Efield and max peak voltage variables and printed them, comparing three antennas: a small one with normal veffective (nonzero), a small on with 0 veffective, and the actual bicone. The electic field was the same for all antennas, but the peak voltages were all very low for the antenna with 0 veffective. <span style="color:#FF0000">Actually, after reinvestigating, it looks like the maximum peak voltages *were* the same between all the antennas.</span></p> <p>I've been looking into using the automatic grid spacing in XF. I think I need to get a better understanding of XF, so I started playing with it to design things in the GUI. I want to be able to make a model using the xmacros that I can look at in the GUI so I can understand all of the functions being used. Since we've checked AraSim pretty extensively, we think that the issue is with XF. I think the grid spacing might be allowing small antennas to appear better than they are.</p> </td> <td> <p>I think to investigate if the problem is in XF we should do a run of the same antenna with different grid spacing and look at the average gain plots. A preliminary test could be to try modeling a small antenna with a very large grid size--if that gives a very high gain, then it would suggest that the issue is with grid spacing being too large for small antennas.</p> <p>I think I'll also keep playing with Karoo. I've been reviewing some ML material to refamiliarize myself and see if I can write a few simple programs. I got Karoo running on OSC last week but I don't really understand the outputs (using the practice dataset).</p> </td> </tr> <tr> <td> <p>Alex P.</p> </td> <td>Worked through more with AraSim looking at Amy's suggestions she sent over the weekend. Was able to print the PeakV and the Electric Fields, the Electric Fields matched and were the same which is what should have happened and the PeakV varied depending on how well it detected the event. Also the trigger threshold is already printed so we looked at that too.</td> <td>We believe that AraSim is functioning properly so next we will look more into XF, and the grid spacing. ProGrid we think is the option from what we talked with Cade but we will continue to look further into it.</td> </tr> <tr> <td>Eliot & Leo</td> <td> <p> </p> </td> <td> <p> </p> </td> </tr> <tr> <td>Evelyn</td> <td> </td> <td> </td> </tr> <tr> <td>Ryan</td> <td>Was added as a collaborator to the paperclip repository on git hub and created a new dev branch and directory. Afterward, I started writing the new roulette algorithm. All changes have been pushed to the githhub repository. </td> <td>Continue writing the roulette algorithm and start work on the github classes on Codecademy. </td> </tr> </tbody> </table> <p> </p>
