Talk with your hands – instructional time-wasting video link
It has been a while since posting about presentation techniques. This time the post remains short. If you are preparing for your SAS2012 or IUMRS-ICEM presentation, and you are looking for that little bit of additional zest to keep your audience awake… Talk with your hands! Italians are well-known for their gesturing during their presentations and [...]
Introducing Scientists: Videos
I have worked with ResearchSEA on getting some videos out there to promote the sciences. I have been interviewing some people, condensing their stories into a minute(-ish) of Youtubey goodness. The videos are available on the new ResearchSEA website here and here. They are the first two, there will be more at a rate of about one [...]
Movie: Monte-carlo fitting of anisotropic scattering
I have worked on monte-carlo procedures for a while now. Initially (while working for Aarhus University), I managed to make these work to extract the particle size distribution from isotropic scattering patterns, and it works fine and quick. Now though, I managed to get this trial-and-error procedure to work for whole 2D pattens as well! [...]
capillary self-absorption paper highlight, and new video
Dear scatterers, Those of you who have been reading this weblog for a while now, may remember the calculation of the sample self-absorption correction for plate-like samples. The result of this was a straightforward equation which could be used to correct the scattering of strongly absorbing samples (>30%) with a plate-like geometry. It was mentioned [...]
Presenting for Scientists – video
If you give bad presentations, you can kill people. If you want to find out why, and get some tips on presentation techniques (the ones I use, anyway), you can watch this video I recorded recently. ( http://www.youtube.com/watch?v=eVtL9NCXyEs ) Comments are always welcome!
Live FT video
A demonstration of the live Fourier Transform showing scattering patterns can be seen here:
More Youtube videos
So, I could not do what I promised last time, the Monte-Carlo fitting works on perfect simulated scattering patterns but is as of yet unable to deal with the addition of a flat background. So I will have to take a raincheck. In the mean time, I have made two videos (part 1 and part [...]
saxsfit software with documentation, fitting function examples and example data
Hi all, I have made some new software available on the “software” page. This is the saxsfit (yes, terrible name, I know) routine I normally use for fitting SAXS curves to model functions. Nothing special, except that it can also deal with (time)series quite nicely. Also there is documentation for some of the packages. I [...]
