Robust Time-Difference-of-Arrival (TDOA) Localization Using Weighted Least Squares with Cone Tangent Plane Constraint [PDF]
Sensors, 2018 Finding the position of a radiative source based on time-difference-of-arrival (TDOA) measurements from spatially separated receivers has been widely applied in sonar, radar, mobile communications and sensor networks.

Non-rigid point cloud registration based lung motion estimation using tangent-plane distance. [PDF]
PLoS ONE, 2018 Accurate estimation of motion field in respiration-correlated 4DCT images, is a precondition for the analysis of patient-specific breathing dynamics and subsequent image-supported treatment planning. However, the lung motion estimation often suffers from

Some Geometric Characterizations of f-Curves Associated with a Plane Curve via Vector Fields
Advances in Mathematical Physics, 2022 The differential geometry of plane curves has many applications in physics especially in mechanics. The curvature of a plane curve plays a role in the centripetal acceleration and the centripetal force of a particle traversing a curved path in a plane ...

Tangents to a multiple plane curve [PDF]
Pacific Journal of Mathematics, 1986 The limiting behavior of the tangents and the flexes are computed as a reduced plane curve degenerates into a multiplicity n plane curve. The main result is that the limit of the flexes are the flexes of the reduced limit curve, the tangents to the reduced limit curve at the base points, and the tangents to the ''first derivative'' of the deformation ...
