![]() ![]() What if I include both the starting and ending points to find the vertical acceleration? Using just these points, I get a vertical acceleration of -39.8 blocks/s 2 (leaving it in units of blocks just in case a block is not 1 meter). Now what about the vertical motion for these points? If this motion does indeed have a constant horizontal velocity, it should be around 40 blocks per second. I could clearly mark the start and the end of the motion along with some points right before it gets to the highest point. This is a little difficult since I can only see the projectile block (or what appears to be the block) for a few frames.įirst, here is a plot of the horizontal position of the block. Why else would he set the virtual camera perpendicular to the motion of the projectile? Perfect for – video analysis with Tracker. The robot creator of that video (I am guessing it was a robot based on the voice) clearly intended me to do this analysis. Video Analysisĭon't pretend like you didn't know this was coming. That is a bit closer, but really I am not satisfied. This would give a vertical acceleration of 8.5 m/s 2. If the length of the block was 0.5 meters, the starting position would just be 21.5 meters. I guess they used a time of 2.3 seconds instead of 2.25 seconds. For information and resources regarding posters, see the Poster Resources and Guides section of the AHA website.This is slightly different than the value from the video. For information about proposals, see the Submitting a Proposalpage. Would you like to submit a poster proposal for the 2016 annual meeting in Atlanta next January? The February 15 deadline for proposals is quickly approaching. The AHA looks forward to further refining the poster session and inviting scholars to enjoy this interactive forum for many annual meetings to come. While one might see the annual meeting as a fly-through based on how much happens so quickly, the poster sessions offer a change of pace from the traditional panel sessions. This range of communication is important in a field where scholars are always plagued with having to prove the significance of their work thus, poster presentations serve as useful development opportunities for emerging scholars. ![]() Rather than scrambling to ask something during the comment portion of a session, onlookers could get a presentation geared toward their own levels of topical expertise on their own time. Greenberg and Juarez’s poster is pictured on the left, with Fred Gibbs’ in the center, and Amy Absher’s on the right.Īccessibility proved to be another benefit I gathered from presenters. For those unfamiliar with the game, Minecraft allows outsiders to access created worlds, and Absher had the game-world replica of New York’s 1939 Flushing Meadows on a fly-through display at her poster. Meanwhile, Amy Absher, from Case Western Reserve University, tackled the computer game Minecraft as a space for history, using the game as the vehicle for students to reconstruct the 1939 New York World’s Fair. ![]() Rob Allen made the trek from Auckland University of Technology, in New Zealand, to display his Spreading the Light project, which offers background on labor figures and the web of organizations present in 1880s New York. The screens also proved useful in the untangling of history itself. For instance, the duo from The New School, Guy Greenberg and Norma Juarez, presented a remarkable digital history project on AIDS activism, which included transcripts, indexes, keywords-the whole nine yards. Computers and tablets allowed the meeting attendees to experience new resources firsthand. Several presenters took things a step further by making their posters interactive. Such visuals also prove very effective at drawing in and engaging passers-by. Even projects that did not rely on images to communicate their research benefitted from a less linear presentation everywhere, engaging mind maps and graphical presentations of textual content could be seen. The simple textual explanation of projects such as these could hardly do justice to the details and scope of the material at hand. Striking visuals, like the video Lisa Rand had on repeat that showed how much fresh space debris is created when Gravity-like scenarios play out, or Christine Axen’s use of GIS mapping to track and illustrate the ownership and use of space in 13th-century Avignon, France, bring projects to life in ways text or a fleeting image in a session PowerPoint fail to do. After getting the initial rundown of each project, a theme emerged around the visual elements each project involved. What led you to opt for a conference poster? I opened my barrage of inquiry with some form of this question. Candidate Lei Duan explains his research on gun ownership policies in early 20th-century China. ![]()
