Description

Mathematica package files (.wl) and aggregate data for the paper "In situ characterization of low-viscosity direct ink writing: stability, wetting, and rotational flows." Code describes image analysis techniques for analyzing stability, wetting, and rotational flows in videos of a direct ink writing process. An example video set is included. "gras" refers to the Grasshopper camera which was used to capture videos from the side (stability/wetting) "flea" refers to the Flea camera which was used to capture videos from the back (rotational flows). -------------------- VIDEO ANALYSIS WORKFLOW 1. calibration.wl describe the nozzle geometry and substrate position for a video 2. extrusionBehaviors.wl detect and analyze fluid surfaces for each frame in a video (or 40-80 frames, for stable flows) 3. aggregation.wl summarize data across many frames, describing average values and characterizing periodicity of droplets 4. displacements.wl analyze xz videos to find particle displacements -------------------- TOOLBOXES fileManagement.wl handling this file naming convention -------------------- DATA summaries4.csv list of aggregate video data thicknesstable.csv aggregate filament height data dispsSummary.csv aggregate particle displacements for rotational flows Example video flea_disps2_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.csv displacements flea_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.avi video from the back gras_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.avi video from the side grasGeoA_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.txt geometry stats about video grasHeights_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.csv table of stage heights in um grasHeights_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.tiff visual representation of tilt grasPositions3_linex_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.csv list of fluid surface measurements over time grasSummary4_T25_H150_FDTS_film_vF1.5_vSfast_171024165320.csv summarized fluid surface measurements over time
