Circle detection using isosceles triangles sampling
Hanqing Zhang, Krister Wiklund, Magnus Andersson
Detection of circular objects in digital images is an important problem in several vision applications. Circle detection using randomized sampling has been developed in recent year…
Investigation of force approximations in tethered cells simulations
Johan Zakrisson, Krister Wiklund, Ove Axner +1
Simulations of tethered cells in viscous sub-layers are frequently performed using the Stokes drag force, but without taking into account contributions from surface corrections, li…
Cell shape identification using digital holographic microscopy
Johan Zakrisson, Staffan Schedin, Magnus Andersson
We present a cost-effective, simple and fast digital holographic microscopy method based upon Rayleigh-Sommerfeld back propagation for identification of the geometrical shape of a…
The biomechanical and structural properties of CS2 fimbriae
Narges Mortezaei, Bhupender Singh, Johan Zakrisson +2
Enterotoxigenic Escherichia coli (ETEC) are a major cause of diarrhea worldwide, and infection of children in underdeveloped countries often leads to high mortality rates. Isolated…
Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles
Magnus Andersson
Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused l…
