Feedback: The simple and best solution 
by Prof. Sigurd Skogestad 

On 09 February 2006, the American Institute of Chemical Engineers CAST division
broadcast a talk by Sigurd on "Feedback: The simple and best solution".
People could view the transparencies and listen to Sigurd speak online.

Unfortunately, there is no recording of the broadcast itself, but you can
here find the transparencies, together with answers to questions which 
the listeners could type in interactively. There is also a video of
slugging which was used in the presentation (slug.wmv) plus a newer
video (not shown during the webcast) with anti-slug experiments from our lab
(labvideo_slugcontrol).
