Concurrent validity of a developed accelerometry-based device for postural sway assessment [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 Postural control is one factor related to falls. Many instruments are available to objectively evaluate postural control performance. However, feasibility and applicability is limited by setting and financial restraints.

Mapless Online Detection of Dynamic Objects in 3D Lidar
, 2018 This paper presents a model-free, setting-independent method for online detection of dynamic objects in 3D lidar data. We explicitly compensate for the moving-while-scanning operation (motion distortion) of present-day 3D spinning lidar sensors.

Particle Dynamics in Damped Nonlinear Quadrupole Ion Traps [PDF]
, 2014 We examine the motions of particles in quadrupole ion traps as a function of damping and trapping forces, including cases where nonlinear damping or nonlinearities in the electric field geometry play significant roles.

Mobility and transverse flow visualization using phase variance contrast with spectral domain optical coherence tomography [PDF]
, 2007 Phase variance-based motion contrast is demonstrated using two phase analysis methods in a spectral domain optical coherence tomography system. Mobility contrast is demonstrated for an intensity matched Intralipid solution placed without flow within ...

3D time series analysis of cell shape using Laplacian approaches [PDF]
, 2013 Background: Fundamental cellular processes such as cell movement, division or food uptake critically depend on cells being able to change shape. Fast acquisition of three-dimensional image time series has now become possible, but we lack efficient tools
