The Graphical System Design Achievement Awards (GSDAA) is the National Instruments annual technical application contest, showcasing the most innovative projects based on NI software and hardware. Technical judges have whittled down more than 150 submissions to 18 finalists, two for each application category.
Now it’s your turn to vote.
This year’s Graphical System Design Achievement Awards ceremony, held during NIWeek at the Four Seasons Hotel Austin, will honor the Community Choice Award Winner: the submission selected by you, the people, the NI community of engineers and scientists. Voting closes on Monday, August 5, 2013 at 5 p.m. CT.
How to vote:
Read the brief description of each submission listed below. You can also read the full paper of each submission by clicking on its hyperlink and downloading the PDF attachment - and they are ALL worth reading in full!
When you are ready to cast your vote, click on the hyperlink for each paper that you like (yes, you can cast more than one vote). Once you’ve navigated to the specific community page for the finalist paper, be sure to click on the “Like” button at the bottom right corner of the page. Once you’ve “Liked” a finalist, you've cast your vote!
Note that while you can “Like” multiple submissions, you are only able to “Like” each finalist once. “Liking” the same document multiple times will not result in multiple votes for the same submission.
Tell your friends, family, co-workers, and anyone else in your online network to vote. Seriously, the more votes the better. But please be cool and don’t try to game the system. Let’s make sure the Community Choice Award is given to the coolest, most-deserving application.
Voting will close on Monday, August 5, 2013 at 5 p.m. CT. The finalist with the most "Likes" will be honored at the GSDAA ceremony on August 6, 2013.
Submit any questions or comments about the voting process in the comments section below.
