Abstract: The disclosure notably relates to a computer-implemented method for analyzing the temporal evolution of a foam sample. The method comprises providing a time-series set of images of a foam sample subject to a shrinking process in a predetermined shrinking direction. The method also comprises generating a spatiotemporal diagram image from the time-series set of images. The spatiotemporal diagram image represents time evolution of a layout of the foam sample in the predetermined shrinking direction. The method also comprises segmenting the spatiotemporal diagram image into a set of segments. The method also comprises creating one or more curves that represent boundaries of the segments. This forms an improved solution for analyzing a foam sample.

Abstract: The invention relates to a method for determining the electrophoretic velocity of droplets of a first fluid in a second fluid, the method comprising: providing a first capillary (3?) having an outlet positioned in a first channel (3); providing a stream of the first fluid in the first capillary and providing a stream of the second fluid in the first channel external to the first capillary, so as to generate droplets of the first fluid in the second fluid at the outlet of the first capillary; transporting the droplets to an observation area (200) in a second channel (11); applying an electric field to the observation area of the second channel; and measuring the velocity of the droplets in the observation area. The invention also relates to a device for determining the electrophoretic velocity of droplets of a first fluid in a second fluid.
