University of Hohenheim, Faculty of Agricultural Sciences, Institute of Agricultural Engineering, Agricultural Engineering in the Tropics and Subtropics
Since March 2013, Matlab Geeks has worked with the University of Hohenheim to analyze bruised mangos (Figure 1) through the use of pulsed phased thermography (PPT) with an infrared video camera. The location, size, and depth of the bruises are to be determined by examining the phase of the Fourier transform of data recorded during the heating and cooling of mangos by heat lamps (Figure 2). Our software has assisted in the testing and analysis performed by a researcher at the university. The deliverables have included code that reads videos and formats them in Matlab, facilitates analysis of preliminary test data to determine optimal testing parameters, performs thermographic signal reconstruction, creates images of phases of mangos in the Fourier domain, assists in the selection of bruised areas, and shows differences between bruised and sound areas. Our code will help in the publication of research papers on this topic. Additionally, this research is intended for commercial application in the mango agricultural sector in Thailand.
NCAA March Madness
March Madness is upon us, and to get a taste for your brackets choices, play around with our Java applet to see the historical win percentages for each round of play. A “NaN” indicates that that matchup has never happened before (i.e. a 16 seed winning the first round will create a “NaN” for the 3rd round winner). For complete data see the post on NCAA tournament seedings.
Choice Reaction Time Task using Java Swing for Chiang Mai University, Department of Physical Therapy, Faculty of Associated Medical Science. We are posting a stripped down version of the application in applet form, with only 10 consecutive choices shown. Try to see how fast your reaction time is along with your accuracy when responding to different shapes.
